Description
Technical field
The utility model belongs to the field of medical instrument technology, relates in particular to a kind of surgical linear cutting stapler, uses
In the progress hysteroscope cutting operation in surgical operation.
Background technology
Linear cutting anastomat is a kind of common medical instrument comprising nail bin, nail anvil, cutter and push-off device；
Nail hole is distributed in nail bin, titanium nail is provided in nail hole.Its course of work is as follows in practice：Clamped with nail bin and nail anvil need into
Row cutting tissue, with push-off device push cutter tissue is cut open, in the process push-off device by titanium follow closely from
Nail anvil is sequentially squeezed out and pushed in nail hole, and the tissue cut open is sutured within first time with titanium nail.It deposits in the prior art
The problem of be, with nail bin and nail anvil clamp tissue carry out operation stitching when, cutter are pushed ahead along cutting groove
When, tissue is under the forward cutting force effect by cutter, it is easy to which generation horizontally slips, and causes to influence suture effect
Fruit.Therefore, how a kind of novel surgical linear cutting stapler is provided, can ensure the process that tissue is sutured in cutting
In effectively overcome cutter generate cutting force, avoid generate human body sliding influence sewing effect be those skilled in the art need
The direction of research.
Utility model content
The purpose of this utility model is to provide a kind of linear cutting anastomat, can avoid human body during suture operation
Tissue generates sliding, ensures the sewing effect to cutting tissue.
A kind of surgical linear cutting stapler, including nail bin, nail anvil, cutter and cutting propeller；The nail bin and nail
Anvil is oppositely arranged, and the surface of the nail bin towards nail anvil side is equipped with cutting groove and nail hole, and the nail hole is distributed in cutting groove
Both sides；Titanium is equipped in the nail hole to follow closely；The cutter are set in cutting groove, and the cutting propeller connection cutter are used for
Cutter are pushed to be moved along cutting groove；Nail pushing plate is connected on the cutting propeller, the nail pushing plate is used in cutting propeller
Push cutter along cutting groove move during titanium nail ejected from nail hole；The nail bin is also set towards one side surface of nail anvil
There are the anti-slop serrations of protrusion.
By using this technical solution：When the human body cut is clamped with nail bin and nail anvil, it is raised in
The anti-slop serrations on nail bin surface increase the contact area of nail bin side and tissue, and anti-skidding fixed work is played to tissue
With, the motive force that cutter generate tissue in cutting process is thus counteracted, ensures that body positions fix, guarantor
Cutting effect is demonstrate,proved.
Preferably, in above-mentioned surgical linear cutting stapler：The anti-slop serrations are divided into two groups, are symmetrically distributed in nail bin court
To the two sides of one side surface of nail anvil, the cutting groove and nail hole are located between two groups of anti-slop serrations.
By using this technical solution：It is two groups that anti-slop serrations, which are symmetrical arranged, and anti-slop serrations is enabled to generate tissue
Stiction advanced optimizes the antiskid effect of anti-slop serrations relative to the symmetrical equal distribution of cutting track.
It is further preferred that in above-mentioned surgical linear cutting stapler：The anti-slop serrations are V word bending shape convex blocks, and its V word
Mouth is arranged towards cutting groove.
By using this technical solution：During cutter are cut, anti-slop serrations generate two to tissue
The oblique active force in a direction is prevented perpendicular to cutter active force and being parallel in the both direction of cutter active force
Tissue generates sliding.
It may further be preferable that the upper surgical linear cutting stapler, it is characterised in that：The end face ratio of the anti-slop serrations
The high 0.05-0.15cm in surface of nail bin towards nail anvil side.
By using this technical solution：It is that this product is mainly used in the shearing and suture for viscera tissue.Through
Repetition test can all reduce the anti-skidding fixed effect of nail bin and nail anvil to tissue if the setting of anti-slop serrations end face is too high or too low
Fruit.
It is even furthermore preferable that in above-mentioned surgical linear cutting stapler：The end face of the anti-slop serrations is equipped with irregular
Particle.
By using this technical solution：The roughness for increasing anti-slop serrations end face increases anti-slop serrations end face and human body
Stiction between tissue.
Compared with prior art, the utility model is simple in structure, easily prepared.People can be avoided during suture operation
Body tissue generates sliding, ensures the sewing effect to cutting tissue.
Description of the drawings
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
Fig. 1 is the structural schematic diagram of embodiment 1；
Fig. 2 is the overlooking structure diagram of nail bin in Fig. 1.
Each reference numeral and component names correspondence are as follows：
1, nail bin；2, nail anvil；3, cutter；4, propeller is cut；11, cutting groove；12, nail hole；13, titanium is followed closely；14, prevent
Slip teeth；41, nail pushing plate.
Specific implementation mode
In order to illustrate more clearly of the technical solution of the utility model, the utility model is made into one below in conjunction with attached drawing
Step description.
It is the structure of the prior art as shown in Figs. 1-2：
A kind of surgical linear cutting stapler, including nail bin 1, nail anvil 2, cutter 3 and cutting propeller 4；The nail bin 1
It is oppositely arranged with nail anvil 2, the surface of the nail bin 1 towards 2 side of nail anvil is equipped with cutting groove 11 and nail hole 12, and the nail hole 12 is divided
It is distributed in the both sides of cutting groove 11；It is equipped with titanium in the nail hole 12 and follows closely 13；The cutter 3 are set in cutting groove 11, the cutting
Propeller 4 connects cutter 3, for pushing cutter 3 to be moved along cutting groove 11；Nail pushing plate is connected on the cutting propeller 4
41, the nail pushing plate 41 is used to that titanium to be followed closely 13 from nail during cutting propeller 4 and cutter 3 is pushed to move along cutting groove 11
It is ejected in hole 12.Wherein, the nail bin 1 is additionally provided with anti-slop serrations 14 towards 2 one side surface of nail anvil.It is two that the anti-slop serrations 14, which are divided to,
Group, is symmetrically distributed in surface both sides of the nail bin 1 towards 2 side of nail anvil, and the cutting groove 11 and nail hole 12 are located at two groups of anti-slop serrations
