Below, the embodiment explanation the present invention shown in reference to the accompanying drawings.
As shown in Figure 1, the related front end of one embodiment of the present invention can be partial to operation conduit 2, for example is used for the diagnosis or the treatment of arrhythmia, dististyle 10 and a plurality of adapter ring 12 before the amphi position end of conduit pipe fitting (duct member) 4 is equipped with.Preceding dististyle 10 and adapter ring 12 as electrode performance function, for example are connected and fixed by the relative conduit pipe fitting 4 such as bonding grade with bonding agent.
Peri position end at conduit pipe fitting 4 is equipped with handle body 20.Inside in conduit pipe fitting 4 and handle body 20 is drawn the admittance line respectively, and the front end of lead is electrically connected with the preceding dististyle 10 and the adapter ring 12 that constitute electrode.In addition, the cardinal extremity of these leads is connected with the adapter 21 of the rearward end that is fixed on handle body shown in Figure 2 20.The action button 22 of the deflection move operation (yaw operation) of the amphi position end be used to carry out conduit pipe fitting 4 is installed on handle body 20 in addition.
Preceding dististyle 10 shown in Figure 1 and adapter ring 12, for example the metal by good conductivity such as aluminum, copper, rustless steel, gold, platinums constitutes.In addition, in order to have the radiography good to X ray, it is preferred that these preceding dististyles 10 and adapter ring 12 are made of platinum etc.Though before the external diameter of dististyle 10 and adapter ring 12 be not particularly limited, with the external diameter equal extent of conduit pipe fitting 4 be preferred, be generally the degree of 0.5～3mm.
The yaw parts are being accommodated near the amphi position end of conduit pipe fitting 4 inside.Do not limit especially as the yaw parts, for example constitute by leaf spring etc.On leaf spring, be connected and fixed as Fig. 2～operation shown in Figure 4 amphi position end of silk thread 30 as these yaw parts.
Though operation is not particularly limited with the external diameter of silk thread 30, is preferably 0.01～0.3mm, more preferably 0.03～0.08mm.This operation is that superelastic alloy constitutes by Ni-Ti for example with silk thread 30, but needn't be made of metal.Operation for example also can be made of high-intensity non-conductive silk thread etc. with silk thread 30.
Operation in the present embodiment, is adjusted operation with behind the tension force of silk thread 30 with the peri position end of silk thread 30, as shown in Figure 2, is fixed on the thread tension adjustor 32.Thread tension adjustor 32 is in the inside that moves axially the handle body 24 that is mounted freely on handle 20.By this thread tension adjustor 32 is fixed on the axial location of handle body 24 internal rules, can adjust the tension force of operation with silk thread 30.
As shown in Figure 2, the peri position end of conduit pipe fitting 4 is fixed on operation with on button 22 and the axis part 28 by sleeve pipe 26.Operation is corresponding with operating portion with button 22 and axis part 28.The inside that axis part 28 is inserted the axis hole 25 that is formed at handle body 24 inside, handle body moves axially free state for 24 one-tenth relatively.
The operator catches handle body 24 with one hand, with button 22, makes axis part 28 relative handle body 24 movable operation vertically with this singlehanded finger manipulation operation.Because axis part 28 is fastened on the peri position end of conduit pipe fitting 4, so when making axis part 28 when handle body 24 moves vertically, the peri position end of conduit pipe fitting 4 is operated relatively with silk thread 30 and relatively moved in the axial direction.In addition, operation is fixed on the front end of silk thread 30 near the amphi position end of being located at conduit pipe fitting 4 the yaw parts, and the peri position end of operating with silk thread 30 is fixed on the thread tension adjustor 32 that is fixed in handle 20.
When making axis part 28 to the amphi position end side shifting, then operation remains fixed in state on the thread tension adjustor 32 with the peri position end of silk thread 30 under, the peri position end of conduit pipe fitting 4 relatively moves to amphi position is distolateral.In this case,, operation is applied tension force with silk thread 30, conduit pipe fitting 4 is axially being applied compression stress by the operation of this axis part 28.In addition, because operation is almost constant with the axial length of silk thread 30 and conduit pipe fitting 4, so conduit pipe fitting 4 and operation will be crooked with silk thread 30.Its result, as shown in Figure 1, the amphi position end of conduit pipe fitting 4 is carried out the action of yaw deflection as shown by arrow A.
That is, the amphi position end of conduit 2 is by the operation button 22 of the handle 20 shown in Figure 1 of X operation vertically, and the A direction is tortuous to be moved thereby can be partial to.In addition,, then inserting under the endoceliac state, can freely set the direction of the A direction of relative conduit 2 if handle body 20 is rotated around axle.
In present embodiment, as shown in Figure 2, on the outer peripheral face of axis part 28, form the conical surface 40.The conical surface 40 is conical surfaces that the distolateral external diameter of the amphi position of past more handle body 24 diminishes more.The axial length of the preferred conical surface 40 and operation usefulness button 22 relative handle body 24 are in the equal in length of axial relatively-movable scope or longer.Specifically, the length that the conical surface 40 is axial is preferably 5～20mm.The mutually countershaft core in awl angle of inclination of the conical surface 40 is preferably the angle of 0.1～2.0 degree.
The maximum outside diameter of the conical surface 40 is sizes little or more equal than the internal diameter of axis hole shown in Figure 2 25, with decision operation with cylindrical shell 28 vertically X move in the inside of axis hole 25.Operation is preferably grown 40～80mm with cylindrical shell 28 axial length than the axial length of the conical surface 40.
Peripheral shape at the amphi position end 24a of handle body 24 becomes outer screw section 51, pro-end shield 44 interior week form female thread portion 52.Outer screw section 51 and the 52 screw thread combinations of female thread portion.The internal diameter of the amphi position end 44a of preceding end shield 44 is littler than the internal diameter in the interior week of the preceding end shield 44 of female thread portion's 52 formation.Between the amphi position end 44a of the amphi position end 24a of handle body 24 and preceding end shield 44, between the periphery of interior week of female thread portion 52 and axis part 28, form O shape annular groove 46.
The O shape that is installed with in O shape annular groove 46 as the annular resilient parts is encircled 42, in its axial both sides packing ring 41 and 43 is installed.The female thread portion 52 of end shield 44 before being screwed into by the outer screw section 51 with handle body 24 regulates the axial length of O shape annular groove 46, O shape ring 42 distortion vertically, the fastening force change of the conical surface 40 of O shape ring 42 relative axis parts 28.
O shape ring 42 for example is made of rubber such as silicone rubber, acrylonitrile-butadiene rubber, fluorubber or synthetic resin etc.It is preferred that packing ring 41,43 for example is made of fluororesin, metal etc.
Fig. 3 is the cutaway view of the major part of presentation graphs 2.As shown in Figure 3, on interior week, utilize screw thread combination fixed ratchet wheel with ring 50 near the cylindrical portions may 44b of the peri position end of preceding end shield 44.That is, as shown in Figure 3, ratchet is the cyclic parts that have with the roughly the same external diameter of internal diameter of cylindrical portions may 44b with ring 50, its outer peripheral portion form can with the bonded pin thread of the female thread in the interior week that is located at cylindrical portions may 44b.In addition, ratchet also can be integrated with realizing on the inner peripheral surface of the means pro-end shield 44 beyond the screw thread combination with ring 50.For example, on the inner peripheral surface of end shield 44, perhaps integrally formed before ratchet can be bonded in ring 50 by injection moulding.
As shown in Figure 4, on the inner peripheral surface of ratchet usefulness ring 50, form and rotate the corresponding Zhou Fangxiang concavo-convex 52 of pitch angle θ.The rotation pitch angle θ of Zhou Fangxiang concavo-convex 52 is between adjacent concavo-convex 52 protuberance and the protuberance or the angle around the axle core between recess and the recess, is preferably 5～10 degree.
In addition, on the outer peripheral face of the handle body 24 of all sides that are positioned at this ring 50, form by the plural number interval doubly of rotating pitch angle θ along Zhou Fangxiang with protuberance 54 with the ratchet of concavo-convex 52 engagements of Zhou Fangxiang.In embodiment shown in Figure 4, the intervals of pressing 90 degree along the outer peripheral face of handle body 24 at Zhou Fangxiang are at integrally formed four ratchets protuberance 54 of the outer peripheral face of handle body 24.Ratchet is equivalent to ratchet sense imparting mechanism with ring 50 and ratchet with protuberance 54.
Then, can be partial to the using method of operating conduit 2 to the related front end of present embodiment describes.The operator catches handle body 24 with one hand,, as shown in Figure 2, operation is operated to being pulled away from direction with the amphi position end of 22 the past of button end shield 44 with button 22 with this singlehanded finger manipulation operation.In this case, because axis part 28 is fastened on the peri position end of conduit pipe fitting 4,, conduit pipe fitting 4 moves axially relatively with silk thread 30 so operating relatively.Its result, as shown in Figure 1, the amphi position end of conduit pipe fitting 4 becomes case of bending as shown by arrow A from linear state.
And in the present embodiment, move to the amphi position end direction relative to handle body 24 by axis part 28, O shape ring 42 relative these axis parts 28 move axially relatively from the big side of the little side direction of the external diameter of the conical surface 40.That is, in this case, answer, O shape ring 42 is increased to the power of the direction of circumferencial direction expansion with this mobile phase.In addition, because the internal diameter of cannelure 46 is constant, so move correspondingly with this, the interval of axis part 28 and O shape annular groove 46 narrows down, O shape ring 42 pushing axis parts 28 and before the power of end shield 44 strengthen, the frictional force of O shape ring 42 and axis part 28 increases.
In addition, make axis part 28 relative to handle body 24 when peri position extreme direction moves, O shape ring 42 relative axis parts 28 are located opposite from the position of the external diameter minimum of the conical surface 40.Therefore, in this case, because the interval of axis part 28 and O shape annular groove 46 is the wideest, so the power minimum of O shape ring 42 pushing axis parts 28 and preceding end shield 44, the frictional force of O shape ring 42 and axis part 28 reduces.Therefore, relatively handle body 24 is to leaving the mobile initial stage that axial direction moves with button 22 making operation, and operation usefulness button 22 is mobile vertically by very light power.
In addition, operate with button 22 even allow finger leave, because the big conical surface 40 of O shape ring 42 and external diameter contacts, therefore owing to its frictional force, operation moving axially with button 22.Therefore, even allow finger leave operation button 22, the amphi position end of conduit pipe fitting 4 as shown in Figure 1 also can keep crooked state.
In the amphi position end of conduit pipe fitting 4 shown in Figure 1 is under the straight condition, against the frictional force of the conical surface 40 and O shape ring 42, as long as it is just passable that operation is moved axially with button 22.At this moment, the O shape ring 42 big outer radius portion from the conical surface 40 move to little outer radius portion, so the frictional force of the conical surface 40 and O shape ring 42 diminishes gradually.
In the related catheter handle 20 of present embodiment, preceding end shield 44 screw threads are combined on the periphery of handle body 24, be screwed into the degree of depth by regulating its screw thread, can adjust the fastening force that O shape is encircled the periphery conical surface 40 of 42 centering shaft portions 28.And, at this moment,, give ratchet sense (snapping sound and sensation) relative to the pitch angle θ that rotates around the axle core of handle body 24 according to preceding end shield 44 by use the engagement of protuberance 54 and Zhou Fangxiang concavo-convex 52 as the ratchet of ratchet sense imparting mechanism.Therefore, the operator can rotate that the screw thread of end shield 44 is screwed into the degree of depth before the inching of pitch angle to each.That is, the operator can encircle 42 fastening force according to the number inching O shape of ratchet sense.
Therefore, the fastening force of O shape ring 42 can be suitably guaranteed, operation button 22 stop easily can be made at any axial location.In addition, the screw thread that can adjust the preceding end shield 44 of relative handle body 24 again is screwed into the degree of depth, the screw thread of end shield 44 was screwed into before the rotation pitch angle θ that can count in accordance with regulations stopped, and can inching O shape encircle 42 fastening force, i.e. the inching operation operating physical force of button 22.In addition, in case after the fastening force of O shape ring 42 is set, because by the engagement of ratchet, limit relative to the rotating of the preceding end shield 44 of handle body 24 with protuberance 54 and Zhou Fangxiang concavo-convex 52, so change few to the timeliness of the fastening force of the conical surface 40 of O shape ring 42.
In addition, the invention is not restricted to above-mentioned embodiment, can carry out various changes.For example, in the above-described embodiment, as shown in Figure 4, uniformly-spaced form four ratchets with protuberances 54 along Zhou Fangxiang in the periphery of handle body 24, but also can be as shown in Figure 5, along Zhou Fangxiang uniformly-spaced or the unequal interval ratchet that forms three or other quantity with protuberance 54.But uniformly-spaced forming three or more ratchets along Zhou Fangxiang on the outer peripheral face of handle body 24 is preferred with protuberance 54.When forming three or more ratchet with protuberance 54, can alleviate relative handle body 24 the rocking of axis part 28 (operating portion) (to the rocking of axial vertical direction).
Or as shown in Figure 6, on the outer peripheral face of handle body 24, form the concavo-convex 52a of Zhou Fangxiang accordingly with rotation pitch angle θ shown in Figure 4, on the inner peripheral surface of ratchet, also can press the plural number interval doubly of rotating the pitch angle and form the ratchet protuberance 54a that meshes with the concavo-convex 52a of Zhou Fangxiang along Zhou Fangxiang with ring 50.Ratchet is equivalent to ratchet sense imparting mechanism with ring 50 and ratchet with protuberance 54.
And then, catheter handle involved in the present invention, the front end that is not limited to illustrated embodiment can be partial to the operation conduit, also goes for other conduit.
