description An end effector assembly of a tissue resecting device and a tissue resecting device including the end effector assembly and a handpiece assembly. The end effector assembly including a proximal hub housing, an inner drive core at least partially disposed within the proximal hub housing, a cutting member extending distally from the proximal hub housing and engaged with the inner drive core such that rotation of the inner drive core rotates the cutting member, and a lock and release mechanism operably coupled between the inner drive core and the proximal hub housing. The lock and release mechanism is transitionable between a locked condition rotationally fixing the inner drive core and the proximal hub housing relative to one another thereby rotationally locking the cutting member, and a release condition enabling relative rotation between the inner drive core and the proximal hub housing thereby enabling rotation of the cutting member.
