Abstract
The utility model relates to an integral nail anvil of a linear cutting anastomat, which is suitable to the forming of an anastomosis nail of the linear cutting anastomat. The integral nail anvil comprises a nail anvil body, four rows of nail forming grooves are arranged on the upper part of the nail anvil body in parallel, a plurality of arc-shaped nail forming grooved holes are arranged on each row of nail forming grooves, semi nail forming grooved holes are staggered in parallel between the inner sides and the outer sides of the forming grooves, a cutter guide groove is arranged in the middle of the nail anvil body, a cutter protection rest avoiding through groove is arranged on the rear part of the nail anvil body, and a nail anvil mounting clamping groove is arranged on the rear end of the nail anvil body. Nail cabin positioning pin positioning holes are arranged on the front ends of the nail forming grooves, a mounting plane is arranged at the bottom of the nail anvil body, and a guide head mounting groove is arranged on the front end of the nail anvil body. The nail anvil body has a T-shaped cross section. The utility model is processed in an integral way, has simple structure, high processing precision, high positioning precision after assembled on an anastomat body, good nail forming effect after percussion and tissue closure and no local tissue bleeding phenomenon, and can alleviate patient pain.
Description
Technical field
The utility model relates to a kind of integral nail anvil of straight-line cutting anastomat, be applicable to linear cutting anastomat anastomosis staple molding usefulness.
Background technology
The nail anvil assembly is made up of nail anvil and nail anvil enhancing support in the linear cutting anastomat at present, and nail anvil and nail anvil strengthen support split processing, by the special fixture assembling, are welded on the corresponding fixed position of device on one's body again.Since change join with welding process in positioning accuracy is exerted an influence, cause locating datum offset, anastomosis staple molding imperfection, not even molding causes anastomosis operation local unsuccessful, organizes not closedly, can cause tissue local hemorrhage.
Summary of the invention
The purpose of this utility model is to provide a kind of integral nail anvil of straight-line cutting anastomat at above-mentioned weak point, nail anvil and enhancing support are arranged to one, integral body processes, simple in structure, the machining accuracy height is assemblied in device positioning accuracy height on one's body, percussion back nail good forming effect, tissue closure is good, the tissue local bleeding can not occur, alleviates the patient suffering.
Integral nail anvil of straight-line cutting anastomat is realized by the following technical solutions: integral nail anvil of straight-line cutting anastomat has the nail anvil body, is provided with four row's nail forming tank on nail anvil body top, and four row's nail forming tank be arranged in parallel.Every row follows closely forming tank and is provided with several circular arc staple forming tank holes, follows closely the molding slotted eye parallel staggered half between inboard and the outside forming tank.Nail forming tank front end is provided with nail bin alignment pin locating hole, is provided with mounting plane in nail anvil body bottom, is provided with the cutter gathering sill at the middle part.Be provided with guide head at nail anvil body front end groove is installed, be provided with cutter at nail anvil body rear portion and protect knife rest and dodge groove, be provided with the nail anvil body in nail anvil body rear end draw-in groove is installed.
Operation principle: be assemblied in the linear cutting anastomat front portion during the supporting use of integral nail anvil of straight-line cutting anastomat and linear cutting anastomat, be applicable to that the molding of linear cutting anastomat anastomosis staple uses.Promote the linear cutting anastomat push button towards device body the place ahead and drive the percussion push jack, promote left push jack in the nail bin mechanism, right push jack, finish tissue and coincide molding in a plurality of anastomosis staples propelling integral nail anvil forming tank; Push button drives the cutting tool rest in the firing lock simultaneously, and cutter are finished tissue is carried out from disconnected, excision in integral nail anvil cutter gathering sill in the drive nail bin mechanism.
Integral nail anvil of straight-line cutting anastomat is reasonable in design, nail anvil and enhancing support are arranged to one, integral body processes, simple in structure, the machining accuracy height is assemblied in device positioning accuracy height on one's body, percussion back nail good forming effect, tissue closure is good, the tissue local bleeding can not occur, alleviates the patient suffering.

The utility model is described in further detail below with reference to accompanying drawing:
Fig. 1 is the integral nail anvil of straight-line cutting anastomat front view.
Fig. 2 is the integral nail anvil of straight-line cutting anastomat right view.
Fig. 3 is the integral nail anvil of straight-line cutting anastomat upward view.
Fig. 4 is the nail forming tank partial enlarged drawing of integral nail anvil of straight-line cutting anastomat.
The specific embodiment
With reference to accompanying drawing 1～4, integral nail anvil of straight-line cutting anastomat has nail anvil body 1, is provided with four row's nail forming tank, 2, four row's forming tank 2 on nail anvil body 1 top and be arranged in parallel.Every row follows closely forming tank 2 and is provided with several circular arc staple forming tank holes 9, and inboard the nail between the forming tank 2 with the outside followed closely the molding slotted eye half parallel interlocking.Nail forming tank 2 front ends are provided with nail bin alignment pin locating hole 4, are provided with mounting plane 7 in nail anvil body 1 bottom, are provided with cutter gathering sill 3 at the middle part.Be provided with guide head at nail anvil body 1 front end groove 8 is installed, be provided with cutter at nail anvil body rear portion and protect knife rest and dodge groove 5, be provided with the nail anvil body in nail anvil body rear end draw-in groove 6 is installed.
Described nail anvil body 1 cross section is " T " font.
