SURGICAL STAPLING STAPLING MACHINE CONTAINING A ONE-TIME LOCKING MECHANISM DRIVED BY ELECTROACTIVE POLYMER TO PREVENT OPERATION

摘要

1. A surgical apparatus comprising:! a handle section made with the functionality of creating a piercing / cutting movement; ! an elongated shaft attached to a portion of the handle; ! a piercing bar installed with the possibility of reciprocating longitudinal movement in an elongated shaft for transmitting piercing / cutting movement; ! an end effector connected to the elongated rod on the distal side and forming a portion of working devices, while the end effector responds to the piercing bar by performing a surgical operation; ! control circuits configured to generate a firmware / cut signal; and! an electric locking mechanism located on the site of working devices and responding to a firmware / cutting signal by changing the state between the locking position and the position without locking the firmware bar. ! 2. The surgical apparatus of claim 1, wherein the electrical interlock mechanism further comprises an electroactive polymer-based drive. ! 3. The surgical apparatus according to claim 2, wherein the piercing bar comprises a lateral surface inclined to overcome, during abduction, the resistance of the electrical locking mechanism in the locked position. ! 4. The surgical apparatus according to claim 2, wherein the drive based on an electroactive polymer comprises a multilayer drive located so as to operate transversely to the axis of movement of the piercing bar. ! 5. The surgical device according to claim 2, in which the drive based on an electroactive polymer contains a proximal directional locking finger, function
