Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Embodiment 1
As shown in figure 1, E is the right side, its opposite direction is a left side, and F is upper, and under its opposite direction is, the utility model provides one kind
Medical stapler component push broach, including：Cutting knife 1, steering linkage member 5, resist-nailed seat 3 and push blade 2, push blade 2 are solid with cutting knife 1
Fixed connection, steering linkage member 5 are fastened on the right-hand member of resist-nailed seat 3, it is characterised in that：The bottom of push blade 2 is provided with a groove 4, groove 4
Depth is more than push blade 2 and the existing interference width of steering linkage member 5.
In the case where not changing the run trace of knife, there is provided the gap between push blade 2 and steering linkage member 5, can be with
So that push broach run in resist-nailed seat it is smooth.If without corresponding concave surface, it will cause knife in operation, when running into corner, knife
Head is lifted up so that push blade 2 is offset downward, and push blade 2 is interfered seriously with steering linkage member 5, is increased frictional resistance, is made
Obtaining whole cutter can not move forward.So setting a groove 4 under push blade 2, such push blade 2 is in moving process
In would not with steering linkage member 5 have lap and influence the movement of push blade 2.
It is a kind of most preferred embodiment to be connected by way of card is set, and other, which are fixedly connected with mode such as bolt and welding, is also
Can with, but processing technology is all more complicated, and does not allow quick detachable.
Embodiment 2
With embodiment 1, difference is other parts：Push blade 2 is welded with cutting knife 1.
The mode of being fixedly connected has a lot, and from welding, technics comparing is simple and using also than stronger, more than welds
