Abstract
The invention relates to an integral nail anvil of a straight-line cutting anastomat, which is suitable for molding anastomsis nails of the straight-line cutting anastomat and is provided with a nail anvil body, wherein the upper part of the nail anvil body is provided with four rows of nail molding grooves which are arranged in parallel, a plurality of arc-shaped nail molding groove holes are arranged on each row of nail molding grooves, a half nail molding groove hole is staggered in parallel between the inside molding groove and the outside molding groove, a cutter guiding groove is arranged in the middle part, the rear part of the nail anvil is provided with a cutter rest avoiding through groove, and the rear end of the nail anvil is provided with a nail anvil body arranging clamping groove. The front end of the nail forming groove is provided with a nail cabin positioning pin positioning hole, the bottom of the nail anvil body is provided with a mounting plane, and the front end of the nail anvil body is provided with a guiding head mounting groove. The cross section of the nail anvil body is in a T shape. The nail anvil is integrally fabricated, has simple structure, high machining precision, high positioning precision when being assembled on a device body, good nail molding effect after being struck and good tissue closure, does not have local bleeding phenomenon of the tissue, and relieves the pain of patients.
Description
Technical field
What the present invention relates to is a kind of integral nail anvil of straight-line cutting anastomat, is 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, through 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 the positioning reference skew, 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 objective of the invention is provides a kind of integral nail anvil of straight-line cutting anastomat to above-mentioned weak point, and nail anvil is arranged to one with strengthening support, and integral body processes; Simple in structure, machining accuracy is high, and positioning accuracy is high on one's body to be assemblied in device; Percussion back nail good forming effect; Tissue closure property is good, the tissue local bleeding can not occur, alleviates the patient suffering.
Integral nail anvil of straight-line cutting anastomat is to adopt following technical scheme to realize: 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 laterally arrange.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 the guide head mount grooves at nail anvil body front end, 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, accomplish 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 accomplished tissue is left 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, and nail anvil is arranged to one with strengthening support, and integral body processes; Simple in structure, machining accuracy is high, and positioning accuracy is high on one's body to be assemblied in device; Percussion back nail good forming effect; Tissue closure property is good, the tissue local bleeding can not occur, alleviates the patient suffering.
Description of drawings
Below will combine accompanying drawing that the present invention is described further:
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 laterally arranges.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 mount grooves 8 at nail anvil body 1 front end, 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.
Said nail anvil body 1 cross section is " T " font.
