The specific embodiment
The present invention is described in detail below in conjunction with each embodiment shown in the drawings; but should be noted that; these embodiments are not limitation of the present invention; the function that those of ordinary skills do according to these embodiments, method or structural equivalent transformation or alternative all belong within protection scope of the present invention.
The word of described expression position and direction in the present invention, all be with the exercises on apparatus author as reference, close operator's a end is near-end, is far-end away from operator's a end.
As shown in Figure 1, sectional perspective sketch map for Endo-GIA 100 of the present invention, it comprises nail-anvil assembly 15, anastomat body 10, percussion handle 11 pivotally is installed on the anastomat body 10, itself and anastomat body 10 are at an angle, when gripping percussion handle 11 and applying active force, percussion handle 11 is close to anastomat body 10, and institute is angle and diminishes gradually.
Above-mentioned nail-anvil assembly 15 comprises nail-anvil cap, nail anvil 151 and pin anvil shaft 152.
The far-end of anastomat body 10 is equipped with nail tube 12, nail tube 12 1 ends have opening, and its inside is formed with certain space, be provided with the pipe 13 that only rises in the inner space of nail tube 12, an above-mentioned end that only rises by pipe 13 has and nail tube 12 opening in the same way, preferably, the central axes that only rises by pipe 13 and follow closely tube 12.
Further, anastomat body 10 also comprises the anvil pull rod 14 that is arranged in the above-mentioned pipe 13 that only rises, the end face of its extended described nail tube 12, described anvil pull rod 14 comprise at least part of flexible part 141 that is contained in the described nail tube 12, and the connecting portion 142 of being located at described flexible part 141 far-ends.Above-mentioned connecting portion 142 is connected removably with above-mentioned nail-anvil assembly 15.
As a kind of embodiment, above-mentioned flexible part 141 can be the flexible pipe of shaping.Particularly, above-mentioned flexible pipe is made up of some tube couplings 140, and the part intensity between the adjacent tube coupling 140 is less, and both are flexible motion relatively, and retractility is preferably arranged.Therefore, above-mentioned flexible pipe bendable is converted into arbitrarily angled.So arrange, in operation, make anvil pull rod 14 can walk around the tissue that stops that it moves ahead.In addition, the above-mentioned opening part that only rises by pipe 13 is provided with guide structure, and guide structure can be fillet structure or level and smooth ramp structure, and so convenient above-mentioned flexible pipe stretches out and contraction.
More specifically, above-mentioned flexible pipe is the waveform metal hose, and metal hose is because the plurality of advantages of himself makes it suit to be applied among the present invention.Particularly, metal hose has good flexibility, corrosion resistance, high temperature resistant, wear-resistant, pull resistance; And flexibly, retractility is preferably arranged between the tube coupling of metal hose, clog-free and stiff; Flexible pipe is in light weight, the bore high conformity; Its flexibility, repeated flex, flexible good; And anti-bending, tensile property, lateral pressure resistant are strong.Further, the diameter of section minimum controllable of metal hose is built in 3mm.
The near-end of above-mentioned anastomat body 10 is provided with adjustment structure, and it is used for advancing of control anvil pull rod 14 or retreats, and above-mentioned adjustment structure comprises adjusting knob 17.When rotation adjusting knob 17 advances with control anvil pull rod 14, the flexible pipe part of anvil pull rod 14 is because the pliability of himself, when touching when stopping the tissue that it advances, its form can change, thereby walk around this tissue, thereby the connecting portion 142 of anvil pull rod 14 is cooperatively interacted together with pin anvil shaft 15.In addition, can also the form of flexible pipe part be changed by external force, to adapt to the demand that the connecting portion 142 of being convenient to anvil pull rod 14 and pin anvil shaft 15 cooperatively interact.
Cooperate with reference to shown in Figure 2, preferably, the inside of above-mentioned flexible pipe also is provided with plastic material and memory material, as a kind of embodiment, above-mentioned plastic material can be plastic metal silk 161, and memory material can be memory wire 162, and two kinds of tinsels twine mutually or parallel arranged forms an integral body together.Wherein, it is arbitrarily angled that above-mentioned plastic metal silk 161 can make flexible pipe 141 be folded into, and can not reply immediately.And memory wire 162 can allow flexible pipe 141 be folded into arbitrarily angled after, still have " trend " that resets, be convenient to anvil pull rod 14 in being returned to the process of original position, flexible pipe 141 also can be returned to smoothly only rise the pipe 13 in.It is more superior that inside is provided with flexible pipe 141 its performances wiry, and the easier barrier that gets around is convenient to arrive at the position of pin anvil shaft 15 in limited space.
In addition, at least part of junction of the connecting portion 142 of above-mentioned anvil pull rod 14, flexible pipe and plastic metal silk 161 and memory wire 162 is for fixedlying connected, for example by firm the linking together of welding manner.
Below in conjunction with accompanying drawing, the work process of Endo-GIA of the present invention is set forth.
Shown in Fig. 3 ~ 5, because the restriction of operative space, state when wherein Fig. 3 represents that anvil pull rod 14 has just begun bending, Endo-GIA 100 of the present invention in use, its anvil pull rod 14 is after screwing out under the control of adjusting knob 17, only need be by very little external force, anvil pull rod 14 is moved or along all side shiftings of barrier according to the direction of pin anvil shaft 15 openings, and then satisfy the demand of operative space or cut-through thing gradually.According to the operative space demand or when the volume of barrier is bigger, anvil pull rod 14 may be perpendicular to the direction motion of nail tube 12, and Fig. 4 represents that namely anvil pull rod 14 can be along moving perpendicular to the direction of nail tube 12, and can not be hindered.Need be when the opposite direction of the opening of following closely tube 12 be moved when anvil pull rod 14, namely shown in Figure 5, flexible pipe can continue bending equally.
At last, as shown in Figure 6, in operation in the limited space, when anvil pull rod 14 is walked around the tissue that stops it, can arrive the position of pin anvil shaft 152, pin anvil shaft 152 and anvil pull rod 14 can be linked together, at this moment, control anvil pull rod 14 reclaims, and is identical until finishing.
The anvil pull rod of Endo-GIA of the present invention easily bends, and bending angle can be regulated arbitrarily, and pliability is good, can satisfy the demand of less operative space or walk around the tissue that stops that it moves ahead, and finishes the identical work of operation smoothly.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and under the situation that does not deviate from spirit of the present invention or basic feature, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in the scope.Any Reference numeral in the claim should be considered as limit related claim.
In addition, be to be understood that, though this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description only is for clarity sake, those skilled in the art should make description as a whole, and the technical scheme among each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
