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.

21. A resectioning assembly for controlling operation of a full thickness resection device, comprising:
-
a flexible drive shaft;
a resection actuating mechanism coupled to the flexible drive shaft, the resection actuating mechanism configured to rotate the flexible drive shaft in a first direction; and
a controlling device engaging the flexible drive shaft to control, as the flexible drive shaft rotates in a second direction, a dissipation of torsional energy stored in the flexible drive shaft during rotation in the first direction. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
