    摘要： The present disclosure relates to a forceps that includes a housing, a cutting assembly, and an actuator. The housing has a shaft attached thereto that extends therefrom and is configured to support a pair of jaw members at a distal end thereof. The jaw members are movable to grasp tissue therebetween. The cutting assembly includes a spring element that has proximal and distal ends. The proximal end of the spring element is fixed to a boss disposed within the housing and the distal end of the spring element includes a cutting edge. The spring element is coiled at a proximal end thereof to create a spring bias against the boss. The actuator is operably coupled to the spring element and is configured to selectively advance the cutting edge of the spring element into the jaw members against the spring bias to sever tissue disposed therebetween.

    摘要： A surgical instrument includes first and second shaft members each having a jaw member disposed at a distal end thereof. One (or both) of the shaft members is moveable with respect to the other from a spaced-apart position to an approximated position for grasping tissue between the jaw members. A first ratchet component is coupled to the first shaft member and defines an engagement plane. A second ratchet component is coupled to the second shaft member and is moveable between a retracted position, wherein the second ratchet component is displaced from the engagement plane, and a deployed position, wherein the second ratchet component is aligned with the engagement plane. When the second ratchet component is in the deployed position, the ratchet components are engageable with one another upon movement of the shaft member(s) to the approximated position to fix the position of the jaw members relative to one another.

    摘要： A forceps includes first and second shafts each having a jaw disposed at an end thereof. At least one jaw is moveable from an open to a closed position for grasping tissue therebetween. At least one jaw includes a blade slot defined therein and extending therealong for reciprocation of a blade therethrough. An actuation assembly is disposed within one of the shafts and is configured for translating the blade between a retracted and an extended position. The blade extends at least partially through the blade slot in the extended position. The actuation assembly includes an actuator extending from the shaft. A compliance member couples the actuator to a cable disposed within the shaft. A blade holder engages the cable and has the blade disposed at an end thereof. At least one pulley is coupled to the cable such that translating the actuator proximally translates the blade distally.

    摘要： A forceps includes a housing having a shaft extending therefrom. The shaft has an end effector assembly that defines a longitudinal axis therethrough. The end effector assembly includes first and second jaw members disposed in opposed relation and moveable from a first, open position to a second, closed position for grasping tissue therebetween and a knife. One or more jaw members include knife blade channels defined therein. Each knife blade channel includes a polygonal longitudinal cross-section defined therein. The knife includes a knife edge and a knife base. The knife base includes a corresponding polygonal longitudinal cross-section. The knife is configured to translate through the knife blade channels and the knife base is configured to slidingly engage the knife base channel having the polygonal cross section upon translation of the knife. In embodiments, the knife blade channel and the knife base have a T-shaped longitudinal cross-section.

    摘要： An electrosurgical pencil is provided and includes an elongated housing having an electrocautery blade supported therein and extending distally from the housing. The electrocautery blade is connected to a source of electrosurgical energy. The pencil further includes a plurality of activation switches supported on the housing for activating electrocautery blade. Each activation switch is configured and adapted to selectively complete a control loop extending from the source of electrosurgical energy upon actuation thereof. In use, actuation of at least one of the plurality of activation switches produces a dividing with hemostatic effect at the electrocautery blade. The electrosurgical pencil further includes at least one voltage divider network supported on the housing. The at least one voltage divider network is electrically connected to the source of electrosurgical energy and controls the intensity of electrosurgical energy being delivered to the electrosurgical pencil.

    摘要： 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.
