Abstract

The utility model is related to manufacture technology field of medical appliance, and in particular to a kind of Medical stapler component is with cutting and stapler.A kind of Medical stapler component cutter, including:Cutter, cutter are made of upper cutter head, blade and lower tool apron, and upper cutter head is arranged on cutter top, and lower tool apron is arranged on cutter lower part, and there is blade blade part and knife spine portion and push plate, the knife spine portion of blade to be fixedly connected with push plate by way of two-sided welding;Lower tool apron top is provided with a protrusion, and protrusion is contacted with push broach slot point contact or line.The utility model provides a kind of Medical stapler component cutter and stapler, it solves since tool apron is square under cutter, it is that face contacts with push broach slot, this way of contact brings larger frictional force, the problem of cutter frictional force larger in sliding process causes cutting to have some setbacks very much, increase operation risk.

Description

A kind of Medical stapler component cutter and stapler
Technical field
The utility model belongs to manufacture technology field of medical appliance, and in particular to a kind of Medical stapler component cutter and Stapler.
Background technology
The application of hysteroscope and various imaging techniques makes surgeon without real in the case of huge wound is caused to patient It operates on, basic process is:After anesthesia of patient, doctor makes a call to the aperture of 3~4 0.5 centimetre or so of diameters in the stomach wall of patient, One of hole is put into microcam, is connected to by microcam on video screen, and other several stomach wall apertures The surgical instruments such as scissors, pliers are then put into, for surgical procedure substantially as abdominal, doctor looks at tissue of the screen to lesion Carry out the sequence of operations such as clamp, identical, cutting.
However when linear cutting anastomat is used, since tool apron is all square under cutter, it is with push broach slot Face contacts, and this way of contact brings larger frictional force, and cutter frictional force larger in sliding process causes cutting very not It is smooth, increase operation risk.
Utility model content
The technical problems to be solved in the utility model is:The design that tool apron is contacted with push broach groove face under cutter can bring larger Frictional force cutter sliding process pole is had some setbacks, increase operation risk.
Technical solution is used by the utility model solves its technical problem:A kind of Medical stapler component is provided with cutting Knife, including:Cutter, cutter are made of upper cutter head, blade and lower tool apron, and upper cutter head is arranged on cutter top, and lower tool apron is arranged on Cutter lower part, blade have blade part and knife spine portion and push plate, and the knife spine portion of blade is consolidated with push plate by way of two-sided welding Fixed connection;Lower tool apron top is provided with a protrusion, and protrusion uses line contact or point contact with push broach slot.
Preferably, the projecting parallel is arc in the section shape of push plate plane.
Preferably, the upper cutter head and/or lower tool apron are provided with through hole, the sliding surface in upper cutter head and/or lower tool apron Upper injection lubricant layer.
The utility model also provides a kind of Medical stapler component for including cutter as described above, including:By supporting nail portion With the resist-nailed seat of connecting portion composition, nail portion and the connecting portion junction supported has angle [alpha], and the α is 175 °~179 °.
The utility model also provides a kind of Medical stapler, including:Identical device assembly as described above.
The utility model also provides a kind of Medical stapler, including:Cutter as described above.
The beneficial effects of the utility model are:
The utility model provides a kind of Medical stapler component cutter, and lower tool apron top is provided with a protrusion, described Protrusion is contacted with the push broach line of rabbet joint, and it is excessive fundamentally to solve frictional force of the cutter in sliding process, makes cutting process very Slack problem.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is a kind of schematic diagram of Medical stapler component cutter of the utility model;
Fig. 2 is a kind of schematic diagram for resist-nailed seat of anastomat that the utility model also provides;
In figure:1. cutter, 11. upper cutter heads, 12. blades, 121. blade parts, 122. knife spine portions, 13. times tool aprons, 14. is convex It rises, 2. push plates, 3. resist-nailed seats, 31 support nail portion, 32. connecting portions.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of Medical stapler component cutter, including:Cutter 1, cutter 1 by Upper cutter head 11, blade 12 and lower tool apron 13 form, and upper cutter head 11 is arranged on 1 top of cutter, and lower tool apron 13 is arranged under cutter 1 Portion, blade 12 have blade part 121 and knife spine portion 122 and push plate 2, and knife spine portion 122 and the push plate 2 of blade 12 pass through welding by both sides The mode connect is fixedly connected;Lower 13 top of tool apron is provided with a protrusion 14, and protrusion 14 is contacted with push broach slot using point contact or line.
By the way of point contact or line contact, protrusion 14 has smaller contact portion to be contacted specific surface is obtained with push broach slot Small frictional force is wanted, frictional force of the cutter 1 in sliding process is reduced, makes cutting process more smoothly.
Embodiment 2
Other parts with embodiment 1, the difference is that:Protrusion 14 is arc parallel to the section shape of 2 plane of push plate.
Arc is a kind of preferred line way of contact, and the protrusion 14 of arc is contacted with having two lines at push broach channel opening, And stability is not ensured more while can reduce contact portion by the way of point contact.
Embodiment 3
Other parts with embodiment 2, the difference is that:Upper cutter head 11 and/or lower tool apron 13 are provided with through hole, in upper slitter In seat 11 and/or lower tool apron 13 lubricant layer is molded on sliding surface.
Injection lubricant layer can reduce frictional force, so as to reduce frictional force of the cutter in sliding process, make to cut through Journey is more smoothly.
Embodiment 4
