Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
Expression position described in the present invention and the word in direction are all using exercises on apparatus author as reference, and be near-end near one end of operator, the one end away from operator is far-end.
As shown in Figure 1, for the sectional perspective schematic diagram of Endo-GIA 100 of the present invention, it comprises nail-anvil assembly 15, anastomat body 10, anastomat body 10 is pivotally provided with percussion handle 11, itself and anastomat body 10 are at an angle, when gripping percussion handle 11 when applying active force, percussion handle 11 is close to anastomat body 10, institute angularly 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 provided with nail barrel 12, nail barrel 12 one end has opening, and its inside is formed with certain space, only tube 13 is provided with in the inner space of nail barrel 12, one end of above-mentioned only tube 13 has and nail barrel 12 opening in the same way, preferably, the central axes of tube 13 and nail barrel 12 is stopped.
Further, anastomat body 10 also comprises the anvil pull rod 14 be arranged in above-mentioned only tube 13, the end face of its extended described nail barrel 12, described anvil pull rod 14 comprises the flexible part 141 be contained at least partly in described nail barrel 12, and is located at the connecting portion 142 of described flexible part 141 far-end.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 partial intensities between adjacent tube coupling 140 is less, and both can flexible motion relatively, has good retractility.Therefore, above-mentioned flexible pipe bendable is converted into arbitrarily angled.Setting like this, in operation, makes anvil pull rod 14 can bypass and stops its tissue moved ahead.In addition, the opening part of above-mentioned only tube 13 is provided with guide structure, and guide structure can be fillet structure or level and smooth ramp structure, so facilitates stretching out and contraction of above-mentioned flexible pipe.
More specifically, above-mentioned flexible pipe is corrugated metal flexible pipe, and metal hose, due to the plurality of advantages of himself, makes it be suitable for being applied in the present invention.Particularly, metal hose has good flexibility, corrosion resistance, high temperature resistant, wear-resistant, pull resistance; And, have good retractility between the tube coupling of metal hose flexibly, clog-free and stiff; Flexible pipe is lightweight, bore concordance is good; Its flexibility, repeated flex, flexible good; And resistance to bending, tensile property, lateral pressure resistant are strong.Further, the diameter of section of metal hose is minimum can be controlled in 3mm.
The near-end of above-mentioned anastomat body 10 is provided with adjustment structure, and it is for controlling advance or the retrogressing of anvil pull rod 14, and above-mentioned adjustment structure comprises adjusting knob 17.When rotation of adjustment knob 17 advances to control anvil pull rod 14, the hose segment of anvil pull rod 14 is due to the pliability of himself, when touching the tissue stopping its advance, its form can change, thus walk around this tissue, thus make together with the connecting portion 142 of anvil pull rod 14 cooperatively interacts with pin anvil shaft 15.In addition, the form of hose segment can also be changed by external force, the demand cooperatively interacted with pin anvil shaft 15 with the connecting portion 142 adapting to be convenient to anvil pull rod 14.
Coordinate with reference to shown in Fig. 2, preferably, the inside of above-mentioned flexible pipe is also 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 are wound around mutually or parallel arranged forms an entirety 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 " of reset, be convenient to anvil pull rod 14 in the process being returned to original position, flexible pipe 141 also can be returned to only in tube 13 smoothly.It is more superior that inside is provided with its performance of flexible pipe 141 wiry, more easily gets around barrier, is convenient to the position arriving at 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 for being fixedly connected with, such as, is firmly linked together by welding manner.
Below in conjunction with accompanying drawing, the work process of Endo-GIA of the present invention is set forth.
Shown in composition graphs 3 ~ 5, due to the restriction of operative space, state when wherein Fig. 3 represents that anvil pull rod 14 just starts bending, Endo-GIA 100 of the present invention in use, after its anvil pull rod 14 screws out under the control of adjusting knob 17, only need by very little external force, anvil pull rod 14 can be made to move according to the direction of pin anvil shaft 15 opening or all sides along barrier are moved, and then meet demand or the cut-through thing gradually of operative space.According to operative space demand or when the volume of barrier is larger time, anvil pull rod 14 may be moved perpendicular to the direction of nail barrel 12, and namely Fig. 4 represents that anvil pull rod 14 can be moved along the direction perpendicular to nail barrel 12, and can not be hindered.When anvil pull rod 14 need be moved towards the opposite direction of the opening of nail barrel 12, namely shown in Fig. 5, flexible pipe can continue to bend equally.
Finally, as shown in Figure 6, in limited in operation space, when anvil pull rod 14 walks around the tissue stopping it, the position of pin anvil shaft 152 can be arrived, pin anvil shaft 152 and anvil pull rod 14 can be linked together, now, control anvil pull rod 14 to reclaim, until complete identical.
The anvil pull rod of Endo-GIA of the present invention easily bends, and bending angle can regulate arbitrarily, and pliability is good, can meet compared with minor operation space demand or walk around stop its tissue moved ahead, complete 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 when not deviating from spirit of the present invention or basic feature, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
