The pain that people brings.
By taking stapler as an example, performed as shown in figure 1, stapler includes operation handle, slender bodies 01 and end
Device 04；Wherein, end effector 04 includes nail anvil 042 and nail kit 041, controls the action of actuator 03 to control by operation handle
Flexible percussion part 02 in shutoff device processed drives the nail anvil 042 of end effector 04 to be closed with nail kit 041, realizes to tissue
Clamp.
As shown in Fig. 2 flexible percussion part 02 distal side (close to the side of user be nearside during operation, remote user
Side be distal side) one end has nail anvil drive division 021 and nail kit limiting section 022, the drive of nearside one end and surgical operating instrument
Distal side one end connection of moving part 03；Wherein, there is bearing pin 023, nail anvil 042, which has, deviates from above-mentioned nail kit on nail anvil drive division 021
041 cambered surface 0421；Nail kit limiting section 022 towards nail kit 041 with nail kit away from nail anvil 042 while offset；With Fig. 2
Exemplified by shown orientation, when distal direction (i.e. to the left) is mobile under the driving of actuator 03 for flexibility percussion part 02, bearing pin 023 and
Cambered surface 0421 offsets, and then drives pivotal axis rotate counterclockwise of the nail anvil 042 between nail anvil 042 and nail kit 041, and then makes end
The nail anvil 042 of end actuator 04 closes with nail kit 041, and actuator 03 continues to drive flexible percussion part 02 distal direction movement
When, realize the driving to the action such as cutting suture in end effector 04.
Therefore, during surgical operating instrument use, the opening and closing of end effector 04 and cutting suture etc. are dynamic
Make to realize driving by flexibility percussion part 02.
But the flexible percussion part 02 in stapler is stacked by multi-disc rigid disk and is welded, and passes through flexibility
Percussion part 02 realizes the effect that flexible percussion part 02 is subject to during the actions such as opening and closing and the cutting suture of end effector 04
Power is very big, the multi-disc rigid disk of the flexible percussion part 02 of composition is scattered, or even causes flexible percussion part 02 to be distorted,
Cause to close between nail anvil 042 and nail kit 041 not in place, make the safety in utilization of stapler relatively low.
