As introducing in United States Patent (USP) publicity 20080116244,20090308909 and 20110155787: known various surgical linear Endo-GIAs are comprised of nail bin groupware, nail-anvil assembly and clamp hook.Nail bin is arranged in nail bin groupware, the nail bin frame of nail bin is installed and is arranged on the interior firing lock of nail bin frame.It is linear that nail bin is, can be both rectilinear, also can be curved.Ejector pin piece and anastomosis staple are installed in nail bin.A plurality of anastomosis staples are staggered in nail bin more than two rows (comprising two rows).On the nail bin frame, briquetting is arranged.Firing lock is tiltedly carved with cutter by push button, slide block, push rod, ejector pin and is formed, and wherein cutter can be according to using needs to install.Nail anvil and nail anvil frame are arranged in nail-anvil assembly.Nail anvil can be made one with the nail anvil frame.It is linear that nail anvil is, can be both rectilinear, also can be curved.Be arranged with the anastomosis staple grooving corresponding with the anastomosis staple position in nail bin on the surface of nail anvil.A plurality of anastomosis staple groovings are being staggered on the surface of nail anvil more than two rows (comprising two rows).Middle part projection and nearside projection are arranged on the nail anvil frame.Clamp hook and nail bin frame are pivotally connected.After nail bin groupware and nail-anvil assembly close up mutually, clamp hook is rotated around nail bin frame pivot, make clamp hook hook middle part projection on the nail anvil frame, the briquetting that drives on the nail bin frame is pressed on the nearside projection of nail anvil frame, make the clamped hook of nail bin groupware and nail-anvil assembly clamp, will wait to coincide clamp tissue between nail anvil and nail bin.
As introducing in United States Patent (USP) publicity 20090308909: the push button of the firing lock of surgical linear Endo-GIA is positioned at the one-sided of nail bin groupware.When the push button promotion slide block of firing lock moves forward in the nail bin frame, the slipper push push rod moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.Anastomosis staple in nail bin takes the shape of the letter U.When the ejector pin piece is released anastomosis staple in nail bin, the nail tip of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, make two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, reach the operation purpose of will tissue coincideing.The accurate operation purpose of coincideing of tissue of coincideing will be waited in order to guarantee to reach, the push button of firing lock needs continuously the anastomosis staple of 80 left and right to be released in nail bin without a break when percussion, and making two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, the active force that surgical doctor is applied on push button is larger.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of this style is: when nail bin groupware and the clamped hook of nail-anvil assembly clamp will be when identical clamp tissue be between nail anvil and nail bin, treated the impact of the anatomical position of identical tissue, the position at the push button place of one-sided placement may be not easy to surgical doctor and apply active force at push button, the operation purpose that tissue accurately coincide thereby impact will be waited to coincide.As introducing in United States Patent (USP) publicity 20080116244: the pivot of the slide block that the push button of the firing lock of surgical linear Endo-GIA can be in being arranged on the nail bin frame rotates.After the pivot of slide block rotated, push button both can be outstanding to the left side of nail bin frame when push button, also can be outstanding to the right side of nail bin frame, be convenient to the position that the surgical doctor selection applies the push button of active force.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of above-mentioned two kinds of styles is: side-prominent to the nail bin frame all the time due to the push button of firing lock, rotate when making the clamped hook clamping of nail bin groupware and nail-anvil assembly around nail bin frame pivot at clamp hook, outstanding push button affects surgical doctor clamp hook is applied active force, thereby impact will be treated identical tissue and accurately be clamped in the operation between nail anvil and nail bin, or cause the operation fatigue of surgical doctor.As introducing in United States Patent (USP) publicity 20110155787: the pivot of the slide block that the push button of the firing lock of surgical linear Endo-GIA can be in being arranged on the nail bin frame rotates.After the pivot of slide block rotated, push button both can be outstanding to the left side of nail bin frame when push button, also can be outstanding to the right side of nail bin frame.Be positioned at the afterbody of nail bin frame due to push button, when the operation that is clamping wait the tissue that coincide, push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force; When push button percussion operation, be convenient to again the position that the surgical doctor selection applies the push button of active force.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of this style is: the afterbody that is positioned at the nail bin frame due to push button, increase the entire length of surgical linear Endo-GIA, made the identical tissue for the treatment of at some anatomical position not have enough operative spaces to offer the operation of surgical linear Endo-GIA.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of above-mentioned three kinds of styles is: first, because push button is given prominence to the one-sided of nail bin frame, when push button is pulled the trigger, surgical doctor only can be at the one-sided active force that applies of surgical linear Endo-GIA, the surgical doctor less to strength, or to cutting the larger operative site of resistance that coincide, for example, identical thicker or harder the waiting of cutting coincide and organizes, or the anastomosis staple at cutting this tissue place that waits to coincide when coincideing last operation, just be difficult to reach and will wait to coincide the operation purpose that tissue accurately coincide; Second, because push button is given prominence to the one-sided of nail bin frame, the point of force application of the slide block of the outstanding position of push button in push button and the nail bin frame away from, therefore, the power that push button acts on slide block forms cutting coincide useful thrust and useless moment of torsion, frictional force between moment of torsion increase slide block and nail bin frame and the distortion of slide block, the resistance thereby the cutting of increase firing lock coincide; The 3rd, when push button begins to pull the trigger, or to complete when percussion when push button, or return when resetting when push button, firing lock is numbness, the also voiceless sound prompting operation technique personnel variation of pulling the trigger process both, thereby may cause the firing lock operate miss.Therefore the firing lock of surgical linear Endo-GIA also need improve.
Obviously can be found out by above-mentioned, a large amount of not in specie surgical linear Endo-GIAs have been designed now, and the development work of the firing lock of new surgical linear Endo-GIA is still continuing, so that the surgical linear Endo-GIA that used in a large number every year in the world is improved further, more convenient, more laborsaving, more reliable when reaching use, the surgical doctor of being more convenient for applies active force and does not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.
Summary of the invention
The object of the invention is to propose a kind of firing lock of surgical linear Endo-GIA, realize that two push buttons draw respectively the left and right sides at the nail bin frame in.Both can the nail bin frame push button in left side launch to the left side of nail bin frame, also can the nail bin frame push button on right side launch to the right side of nail bin frame, can also the nail bin frame two push buttons of both sides launch to the left and right sides of nail bin frame respectively.Thereby both reach when the operation that was clamping wait the tissue that coincide, push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force; When push button percussion operation, be convenient to the position that the surgical doctor selection applies the push button of active force again; Also do not increase the entire length of surgical linear Endo-GIA, do not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.
Another object of the present invention is to propose a kind of firing lock of surgical linear Endo-GIA, the point of force application of realizing the push button outstanding position slide block in push button and the nail bin frame close to, reduce as far as possible slide block and the frictional force between the nail bin frame and the distortion of slide block that moment of torsion produces, thereby reach the result of use of the identical resistance of cutting that reduces firing lock.
A further object of the present invention is to propose a kind of firing lock of surgical linear Endo-GIA, realize the flexible projection of nearside of slide block, when push button be in when pulling the trigger state or when push button be in when completing the percussion state, maybe when beginning to promote push button, the resistance that the change elastic projection moves is also sounded, and pulls the trigger the result of use of the variation of process thereby reach firing lock by feel and sound double-reminding operation technique personnel.
At present, known surgical linear Endo-GIA is comprised of nail bin groupware, nail-anvil assembly and clamp hook.
Nail bin is arranged in nail bin groupware, the nail bin frame of nail bin is installed and is arranged on the interior firing lock of nail bin frame.It is linear that nail bin is, can be both rectilinear, also can be curved.Ejector pin piece and anastomosis staple are installed in nail bin.A plurality of anastomosis staples are staggered in nail bin more than two rows (comprising two rows).On the nail bin frame, briquetting is arranged.
Nail anvil and nail anvil frame are arranged in nail-anvil assembly.Nail anvil can be made one with the nail anvil frame.It is linear that nail anvil is, can be both rectilinear, also can be curved.Be arranged with the anastomosis staple grooving corresponding with the anastomosis staple position in nail bin on the surface of nail anvil.A plurality of anastomosis staple groovings are being staggered on the surface of nail anvil more than two rows (comprising two rows).Middle part projection and nearside projection are arranged on the nail anvil frame.
Clamp hook and nail bin frame are pivotally connected.After nail bin groupware and nail-anvil assembly close up mutually, clamp hook is rotated around nail bin frame pivot, make clamp hook hook middle part projection on the nail anvil frame, the briquetting that drives on the nail bin frame is pressed on the nearside projection of nail anvil frame, makes the clamped hook clamping of nail bin groupware and nail-anvil assembly.
Task of the present invention is achieved through the following technical solutions:
The firing lock of surgical linear Endo-GIA of the present invention is tiltedly carved with cutter by push button, slide block, push rod, ejector pin and is formed.Two push buttons lay respectively at the left and right sides of nail bin frame.Two push buttons have respectively pivot hole.Slide block slides before and after being constrained in the nail bin frame.There is a pivot at the slide block middle part.Be enclosed within on the same pivot of slide block by pivot hole after two push button overlapping placements in up and down.Two push buttons can be separately rotate around the pivot of slide block.After the pivot of slide block rotated, push button launched to the outside of nail bin frame when each push button.Both can the nail bin frame push button in left side launch to the left side of nail bin frame, also can the nail bin frame push button on right side launch to the right side of nail bin frame, can also the nail bin frame two push buttons of both sides launch to the left and right sides of nail bin frame respectively.When push button promotion slide block moves forward in the nail bin frame, the slipper push push rod moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.
Like this, two push buttons draw respectively the left and right sides at the nail bin frame in, both can the nail bin frame push button in left side launch to the left side of nail bin frame, also can the nail bin frame push button on right side launch to the right side of nail bin frame, can also the nail bin frame two push buttons of both sides launch to the left and right sides of nail bin frame respectively.When push button promotion slide block moves forward in the nail bin frame, the slipper push push rod moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.Firing lock is when the operation that is clamping wait the tissue that coincide, and push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force.Firing lock is when push button percussion operation, surgical doctor can coincide according to cutting and treat thickness and the soft or hard of identical tissue, or whether this tissue place of waiting to coincide has anastomosis staple when coincideing last operation according to cutting, or big or small according to the strength of surgical doctor, select one hand or both hands to apply the position of the push button of active force.Firing lock also reaches the entire length that does not increase the surgical linear Endo-GIA, does not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.
Two push buttons of surgical linear Endo-GIA of the present invention can have respectively pivot hole and arcuate groove, the wing that launch the left and right sides that the slide block far-end can oriented nail bin frame.When each push button after the pivot of slide block rotates, push button launches to the outside of nail bin frame, the arcuate groove of push button is inserted on the wing of slide block, push button makes slide block move forward in the nail bin frame by the wing that arcuate groove promotes slide block, slide block promotes push rod again and moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.
Like this, because push button makes slide block move forward in the nail bin frame by the wing that arcuate groove promotes slide block, therefore the point of force application of the slide block of the outstanding position of push button in push button and the nail bin frame close to, can reduce as far as possible slide block and the frictional force between the nail bin frame and the distortion of slide block that moment of torsion produces, thereby reach the result of use of the identical resistance of cutting that reduces firing lock.
The pivot nearside of slide block can have chute.Two push buttons can have respectively projection.The left and right sides of the near-end of nail bin frame can be jagged respectively.When each push button was drawn close the side of nail bin frame, the projection of push button was positioned at the chute of slide block.When each push button rotates when launching to the outside of nail bin frame around the pivot of slide block, the projection of push button shift out from the indentation, there of nail bin frame slide block the pivot nearside chute and lean against on the side of nail bin frame.When promoting to move forward to the push button that launch in the outside of nail bin frame, the push button that launches to the outside of nail bin frame promotes slide block and moves forward in the nail bin frame, and the projection of the push button that does not launch to the outside of nail bin frame is constrained in the chute of pivot nearside of slide block by the nail bin frame and moves forward.When the push button that launches to the outside of nail bin frame moves backward, the projection of the push button that launches to the outside of nail bin frame leans against on the side of nail bin frame, stop push button to rotate around the pivot of slide block, thereby make the push button band movable slider that launches to the outside of nail bin frame move backward in the nail bin frame.
In the chute of the pivot of slide block, projection can be arranged.Can be fluted on the projection of push button.When push button was drawn close the side of nail bin frame, the groove on the projection of push button was stuck on the projection of chute of slide block, makes push button be constrained on slide block.Rotate when launching to the outside of nail bin frame when promoting the pivot of push button around slide block, the groove on the projection of push button breaks away from the constraint of the projection on the chute of slide block.
Can there be key the both sides of slide block.Can there be keyway the inboard of nail bin frame.The key of slide block is constrained on and in the keyway of nail bin frame inboard, slide block is constrained in the nail bin frame to move forward and backward.
The nearside of slide block can flexible projection.The near-end of the bottom of nail bin frame and middle part can be porose respectively.When push button is in when pulling the trigger state, the elastic projection of slide block springs in the proximal orifice of bottom of nail bin frame, slide block is constrained in the near-end of nail bin frame.When push button is in when completing the percussion state, the elastic projection of slide block springs in the mider hole of bottom of nail bin frame, slide block is constrained in the middle part of nail bin frame.When beginning to promote push button, act on the hole of bottom that making every effort to overcome on push button take the nail bin frame to the constraint of the elastic projection of slide block, make push button promote slide block and move forward and backward in the nail bin frame.
Like this, when push button be in when pulling the trigger state or when push button be in when completing the percussion state, maybe when beginning to promote push button, the firing lock of surgical linear Endo-GIA of the present invention is by the resistance that changes elastic projection and move and sound, and pulls the trigger the result of use of the variation of process thereby reach firing lock by feel and sound double-reminding operation technique personnel.
The near-end of the push rod of surgical linear Endo-GIA of the present invention can have the U-shaped fork, on slide block, U-lag can be arranged.In U-lag on the near-end U-shaped fork insertion slide block of push rod, make slide block can promote push rod and move forward and backward in the nail bin frame.
The far-end of push rod can have the U-shaped fork.Ejector pin is tiltedly carved can U-lag.The far-end U-shaped of push rod fork inserts in the U-lag that ejector pin tiltedly carves, and makes push rod can promote ejector pin and tiltedly carves in the nail bin frame and move forward and backward.
Can there be elongated slot at the middle part of push rod.Can there be alignment pin at the middle part of nail bin frame.The alignment pin at nail bin frame middle part inserts in the elongated slot of push rod.When push button was in until firing position, the alignment pin gear in the middle part of the nail bin frame was at the far-end of the elongated slot of push rod, and the constraint push rod only can move forward in the nail bin frame.When push button is in when completing firing position, the alignment pin gear at nail bin frame middle part is in the proximal end of the elongated slot of push rod, and the constraint push rod only can move in the nail bin frame backward.

According to above-mentioned detailed introduction as can be known, compare with existing various surgical linear Endo-GIAs, the firing lock of surgical linear Endo-GIA of the present invention has following technique effect:
The push button of the firing lock of more existing surgical linear Endo-GIAs is positioned at the one-sided of nail bin groupware.When the push button promotion slide block of firing lock moves forward in the nail bin frame, the slipper push push rod moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.Anastomosis staple in nail bin takes the shape of the letter U.When the ejector pin piece is released anastomosis staple in nail bin, the nail tip of the anastomosis staple of U-shaped is pressed on the grooving of nail anvil, make two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, reach the operation purpose of will tissue coincideing.The accurate operation purpose of coincideing of tissue of coincideing will be waited in order to guarantee to reach, the push button of firing lock needs continuously the anastomosis staple of 80 left and right to be released in nail bin without a break when percussion, and making two nail lower limbs of the anastomosis staple of U-shaped bend to the anastomosis staple of B shape along grooving, the active force that surgical doctor is applied on push button is larger.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of this style is: when nail bin groupware and the clamped hook of nail-anvil assembly clamp will be when identical clamp tissue be between nail anvil and nail bin, treated the impact of the anatomical position of identical tissue, the position at the push button place of one-sided placement may be not easy to surgical doctor and apply active force at push button, the operation purpose that tissue accurately coincide thereby impact will be waited to coincide.The push button of the firing lock of existing other surgical linear Endo-GIAs can be in being arranged on the nail bin frame the pivot of slide block rotate.After the pivot of slide block rotated, push button both can be outstanding to the left side of nail bin frame when push button, also can be outstanding to the right side of nail bin frame, be convenient to the position that the surgical doctor selection applies the push button of active force.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of above-mentioned two kinds of styles is: side-prominent to the nail bin frame all the time due to the push button of firing lock, rotate when making the clamped hook clamping of nail bin groupware and nail-anvil assembly around nail bin frame pivot at clamp hook, outstanding push button affects surgical doctor clamp hook is applied active force, thereby impact will be treated identical tissue and accurately be clamped in the operation between nail anvil and nail bin, or cause the operation fatigue of surgical doctor.The push button of the existing firing lock that also has some surgical linear Endo-GIAs can be in being arranged on the nail bin frame the pivot of slide block rotate.After the pivot of slide block rotated, push button both can be outstanding to the left side of nail bin frame when push button, also can be outstanding to the right side of nail bin frame.Be positioned at the afterbody of nail bin frame due to push button, when the operation that is clamping wait the tissue that coincide, push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force; When push button percussion operation, be convenient to again the position that the surgical doctor selection applies the push button of active force.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of this style is: the afterbody that is positioned at the nail bin frame due to push button, increase the entire length of surgical linear Endo-GIA, made the identical tissue for the treatment of at some anatomical position not have enough operative spaces to offer the operation of surgical linear Endo-GIA.The unsatisfactory place of the firing lock of the surgical linear Endo-GIA of above-mentioned three kinds of styles is: first, because push button is given prominence to the one-sided of nail bin frame, when push button is pulled the trigger, surgical doctor only can be at the one-sided active force that applies of surgical linear Endo-GIA, the surgical doctor less to strength, or to cutting the larger operative site of resistance that coincide, for example, identical thicker or harder the waiting of cutting coincide and organizes, or the anastomosis staple at cutting this tissue place that waits to coincide when coincideing last operation, just be difficult to reach and will wait to coincide the operation purpose that tissue accurately coincide; Second, because push button is given prominence to the one-sided of nail bin frame, the point of force application of the slide block of the outstanding position of push button in push button and the nail bin frame away from, therefore, the power that push button acts on slide block forms cutting coincide useful thrust and useless moment of torsion, frictional force between moment of torsion increase slide block and nail bin frame and the distortion of slide block, the resistance thereby the cutting of increase firing lock coincide; The 3rd, when push button begins to pull the trigger, or to complete when percussion when push button, or return when resetting when push button, firing lock is numbness, the also voiceless sound prompting operation technique personnel variation of pulling the trigger process both, thereby may cause the firing lock operate miss.Therefore the firing lock of existing surgical linear Endo-GIA also need improve.
Two push buttons of the firing lock of surgical linear Endo-GIA of the present invention rotate around the pivot of slide block separately.After the pivot of slide block rotated, push button launched to the outside of nail bin frame when each push button.Both can the nail bin frame push button in left side launch to the left side of nail bin frame, also can the nail bin frame push button on right side launch to the right side of nail bin frame, can also the nail bin frame two push buttons of both sides launch to the left and right sides of nail bin frame respectively.When push button promotion slide block moves forward in the nail bin frame, the slipper push push rod moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.Compare with existing surgical linear Endo-GIA, the firing lock of surgical linear Endo-GIA of the present invention both reached and was clamping when coincideing the operation of organizing, push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force; Again when push button percussion operation, surgical doctor can also coincide according to cutting and treat thickness and the soft or hard of identical tissue, or whether this tissue place of waiting to coincide has anastomosis staple when coincideing last operation according to cutting, or big or small according to the strength of surgical doctor, select one hand or both hands to apply the position of the push button of active force; Also do not increase the entire length of surgical linear Endo-GIA, do not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.
Two push buttons of the firing lock of surgical linear Endo-GIA of the present invention have respectively pivot hole and arcuate groove, the wing that launch the left and right sides of the oriented nail bin frame of slide block far-end.When each push button after the pivot of slide block rotates, push button launches to the outside of nail bin frame, the arcuate groove of push button is inserted on the wing of slide block, push button makes slide block move forward in the nail bin frame by the wing that arcuate groove promotes slide block, slide block promotes push rod again and moves forward in the nail bin frame, push rod promotes ejector pin again and tiltedly carves with cutter and move forward in the nail bin frame, and ejector pin is tiltedly carved and promoted successively each ejector pin piece again anastomosis staple is released in nail bin.Compare with existing surgical linear Endo-GIA, because the push button of the firing lock of surgical linear Endo-GIA of the present invention makes slide block move forward in the nail bin frame by the wing that arcuate groove promotes slide block, therefore the point of force application of the slide block of the outstanding position of push button in push button and the nail bin frame close to, can reduce as far as possible slide block and the frictional force between the nail bin frame and the distortion of slide block that moment of torsion produces, thereby reach the result of use of the identical resistance of cutting that reduces firing lock.
The firing lock of surgical linear Endo-GIA of the present invention, when push button is in when pulling the trigger state, the elastic projection of slide block springs in the proximal orifice of bottom of nail bin frame, slide block is constrained in the near-end of nail bin frame; When push button is in when completing the percussion state, the elastic projection of slide block springs in the mider hole of bottom of nail bin frame, slide block is constrained in the middle part of nail bin frame; When beginning to promote push button, act on the hole of bottom that making every effort to overcome on push button take the nail bin frame to the constraint of the elastic projection of slide block, make push button promote slide block and move forward and backward in the nail bin frame.Therefore, when push button be in when pulling the trigger state or when push button be in when completing the percussion state, maybe when beginning to promote push button, compare with existing surgical linear Endo-GIA, the firing lock of surgical linear Endo-GIA of the present invention is by the resistance that changes elastic projection and move and sound, and pulls the trigger the result of use of the variation of process thereby reach firing lock by feel and sound double-reminding operation technique personnel.
The surgeon is when using surgical linear Endo-GIA of the present invention, two push buttons of firing lock draw respectively the left and right sides at the nail bin frame in, both can the nail bin frame push button in left side launch to the left side of nail bin frame, also can the nail bin frame push button on right side launch to the right side of nail bin frame, can also the nail bin frame two push buttons of both sides launch to the left and right sides of nail bin frame respectively.Thereby reach when the operation that is clamping wait the tissue that coincide, push button is any side-prominent to the nail bin frame not, do not affect surgical doctor clamp hook is applied active force; When push button percussion operation, the resistance of firing lock is less, surgical doctor can also coincide according to cutting and treat thickness and the soft or hard of identical tissue, or whether this tissue place of waiting to coincide has anastomosis staple when coincideing last operation according to cutting, or big or small according to the strength of surgical doctor, select one hand or both hands to apply the position of the push button of active force; Also do not increase the entire length of surgical linear Endo-GIA, do not reduce the surgical effect of the operation subject range of surgical linear Endo-GIA.When push button be in when pulling the trigger state or when push button be in when completing the percussion state, maybe when beginning to promote push button, the firing lock of surgical linear Endo-GIA of the present invention is by the resistance that changes elastic projection and move and sound, and pulls the trigger the result of use of the variation of process thereby reach firing lock by feel and sound double-reminding operation technique personnel.
So can find out that the above-mentioned target of stating comprises by front those shown targets of explanation being effectively achieved.Described here is only the typical best form of implementation of the present patent application, can do some to said structure and change also without prejudice to the spirit and scope of the present invention.The present invention is not limited to the detail of stating here, is apparent any improvement or remodeling and should keep affiliated field secondary technology personnel as stating in the restriction of claim.
