Abstract

A control mechanism for a resectioning device, comprises a first actuator coupled to a flexible drive shaft for actuating a first mechanism when operated in a first direction and for actuating, when operated in a second direction, a second mechanism and a first lockout mechanism coupled to the first actuator for preventing actuation of the first actuator in the second direction before a predetermined amount of actuation in the first direction has been completed. Furthermore, mechanisms are provided to control the release during operation in a second direction of torsional energy stored in a flexible drive shaft during operation in a first direction.
