Specific implementation mode
Embodiment 1：
An embodiment of the present invention provides a kind of stapler with aid in tissue positioning device, institutes as shown in Figure 1, Figure 2 and Figure 3
Show, above-mentioned aid in tissue positioning device includes cutter 1, cutter auxiliary piece 3 and cutter pin 15, above-mentioned cutter 1 with it is upper
It states cutter auxiliary piece 3 and knife assembly 10 is fixed as by above-mentioned cutter pin 15.Above-mentioned stapler further includes nail anvil 2, on
Knife assembly 10 is stated to be slidably connected with above-mentioned nail anvil 2 by above-mentioned cutter pin 15.
Above-mentioned cutter 1 as shown in Figure 4, Fig. 5 are the partial enlarged view of Fig. 4, and Fig. 6 is another variation of Fig. 5,
As shown in Figures 5 and 6, above-mentioned cutter 1 are equipped with blade 11 and raised arm, and the angle of above-mentioned blade 11 and above-mentioned raised arm is
Acute angle, above-mentioned protrusion arm includes convex cantilever lifting 13 and lower convexity arm 14, the angle 12 of above-mentioned blade 11 and above-mentioned convex cantilever lifting 13
