ROTATION ASSEMBLY FOR A SURGICAL DEVICE A surgical device (10) comprising: an actuator assembly (12)； an adapter assembly (14) including a rotation assembly (26) and an elongated body portion (24), the rotation assembly (26) including an inner housing (62) and a rotation knob (60), the inner housing (62) defining a longitudinal axis and being releasably coupled to the actuator assembly (12), the rotation knob (60) being rotatably supported about the inner housing (62) and the elongated body portion (24) being supported on the rotation knob (60) such that rotation of the rotation knob (60) about the inner housing (62) causes corresponding rotation of the elongated body portion (3) about the longitudinal axis of the inner housing (62)； and a tool assembly (16) supported on a distal portion of the elongated body portion (24)； wherein the rotation knob (60) supports a stop and the inner housing (62) supports a stop member, the stop having first and second stop surfaces, each of the first and second stop surfaces being positioned to engage the stop member to limit a degree of rotation of the rotation knob (60) in relation to the inner housing (62).
