Distal end end face and the first moving component 13 proximal face along the axial face of shell 15 and at a distance of certain interval, which is less than
Spacing between first moving component, 13 initial position and active position, the curved surfaces of stressed member 422 are resisted against shifting part 421
The groove of distal end, linkage part 41 is in the 4th position at this time.
After the anastomosis procedure for completing tissue, operator unclamps handle, and the first moving component 13 is in the first return unit 12
Position is returned to by active position under the action of first biasing force, while the first moving component 13 driving linkage part 41 is whole
Body moves in a second direction, and the distal end of the linkage part 41 is finally driven to be supported in the axial direction in the first moving component 13
Simultaneously further compress the 4th return unit 423 in proximal end；Second guide surface 413 and 2242 upper limit of mounting portion protrusion on linkage part 41
2243 the first arcwall face 2248 abuts and retention bead 2243 is driven to move towards far from 141 direction of resigning region, and then drives
Second part 2246 leaves resigning region 141, so that first part 2245 enters in first sliding groove 2231, the second moving component
21 are changed into moving condition by stationary state, i.e., the described lug boss 412 acts on the locking piece 224, so that the locking piece
224 are detached from second moving component 21 along far from axially direction, and accordingly, position-limit mechanism prevents that secondary firing lock opens
Dynamic, stapler is in percussion failure state as shown in figure 17.
The stapler can start automatically position-limit mechanism insurance function after operator carries out first time percussion, and stapler is certainly
It is dynamic to enter percussion failure state, it can completely avoid and stapler is fired again because accidentally touching handle after anastomosis procedure to cause
The case where anastomosis operation fails, it is highly reliable.
