Device and method for controlling compression of tissue

摘要

A method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit.

主权项

1. A surgical device, comprising:
a first clamping member; a second clamping member; an electric motor configured to drive at least one of the first and second clamping members toward a predetermined tissue gap between the clamping members; and a control unit configured to monitor the electric motor and to control the motor to limit a mechanical energy applied to the tissue by the clamping members in response to monitoring of the electric motor.
