ELECTRO-MECHANICAL SURGICAL DEVICE WITH DATA MEMORY UNIT

摘要

An electro-mechanical surgical device includes: a housing; an elongated shaf t extending from the housing, a distal end of the elongated shaft being detachably coupleable to a surgical instrument; at least two axially rotatab le drive shafts disposed within the elongated shaft, a distal end of each of th e drive shafts being configured to couple with the surgical instrument; a steering cable arrangement, the steering cable arrangement being configured to steer the distal end of the elongated shaft; and a motor system disposed within the housing, the motor system being configured to drive the drive shafts and the steering cable arrangement. A control system may be provided for controlling the motor system. A remote control unit may also be provided for controlling the motor system via the control system. Sensors, such as optical of Hall-effect devices, may be provided for determining the position of the elements of the surgical instrument based on the detected rotation of the drive shafts. A memory unit stores a plurality of operating programs or algorithms, each corresponding to a type of surgical instrument attachable t o the electro-mechanical surgical device. The control system reads or selects from the plurality of operating programs or algorithms, the operating progra m or algorithm corresponding to the type of surgical instrument attached to th e electro-mechanical surgical device.
