EMERGENCY RETRACTION FOR ELECTRO-MECHANICAL SURGICAL DEVICES AND SYSTEMS

摘要

The present disclosure relates to an electromechanical surgical system including a surgical instrument having a controller, and an end effector selectively and removably connectable to the surgical instrument, wherein the controller is configured to enter an emergency retraction mode when at least one input element of the surgical system is incapable of providing control signals to the controller to operate a motor, wherein the emergency retraction mode activates the motor to withdraw a drive assembly from any advanced position thereof.

主权项

1. An electromechanical surgical system, comprising:
a hand-held surgical instrument including:
a handle housing;a motor disposed within the handle housing;a controller disposed within the handle housing and being in electrical communication with the motor;a battery selectively, removably insertable into the handle housing and being in electrical communication with at least one of the motor and the controller when disposed within the handle housing; andat least one input element supported on the handle housing and actuatable by a user to send control signals to the controller to operate the motor; an end effector selectively and removably connectable to the surgical instrument, the end effector including:
a jaw assembly having a staple cartridge containing a plurality of staples and an anvil to form the plurality of staples upon firing; anda drive assembly at least partially located within the jaw assembly and operatively connectable to the motor when the end effector is connected to the surgical instrument for actuation by the motor; wherein the controller is configured to enter an emergency retraction mode when the at least one input element is incapable of providing control signals to the controller to operate the motor, wherein the emergency refraction mode activates the motor to withdraw the drive assembly from any advanced position thereof.
