Zusammenfassung: | A forceps includes first and second shafts having a jaw connected thereto. At least one jaw is moveable from an open to a closed position and includes a blade slot extending therealong configured for reciprocation of a blade therethrough. An actuation assembly is disposed within one shaft and is configured for translating the blade between retracted and extended positions. The blade extends at least partially through the blade slot in the extended position. The actuation assembly includes an actuator engaged to a belt disposed within the shaft. The belt is configured for rotation about at least one pulley. A blade holder having the blade connected thereto is engaged to the belt. The blade holder defines a pre-determined load limit that, when exceeded, disengages the blade holder from the belt. Translating the actuator proximally translates the blade distally to the extended position when the blade holder is engaged to the belt. |
