Abstract: A forceps includes an end effector assembly having first and second jaw members movable between a spaced-apart position and an approximated position for grasping tissue therebetween. A knife assembly having a cutting blade disposed at a distal end thereof is also provided. The knife assembly is translatable relative to the end effector assembly between a retracted position and an extended position, wherein the cutting blade extends between the jaw members to cut tissue grasped therebetween. The knife assembly includes a proximal component and a first distal component that includes the cutting blade. The proximal and first distal components are removably coupled to one another to facilitate replacement of the first distal component. Methods of preparing such forceps for reuse are also provided.

Abstract: A method of manufacturing a shaft of a surgical instrument including forming a proximal segment of the shaft to include one or more features for operably engaging the shaft to a first component of the surgical instrument, forming a distal segment of the shaft to include one or more features for operably engaging the shaft to a second component of the surgical instrument and forming an intermediate segment of the shaft. The proximal segment is welded to a proximal end of the intermediate segment; and the distal segment is welded to a distal end of the intermediate segment. The proximal and distal segments are welded to the intermediate segment such that the one or more features thereof are aligned in a pre-determined orientation relative to one another.

Abstract: A medical device may include one or more operable components and one or more limited-use portions. The limited-use portion(s) is configured to transition from a first state to a second state upon being subjected to sterilization above a sterilization threshold. In the second state, the limited-use portion(s) inhibit the operability of the one or more operable components.

Abstract: A forceps includes an end effector assembly having first and second jaw members. Each jaw member includes a bifurcated proximal flange extending therefrom defining first and second spaced-apart flange components. The first flange components are pivotably engaged to one another via a first engagement portion and the second flange components are pivotably engaged to one another via a second engagement portion. One or both of the jaw members is pivotable relative to the other about the first and second engagement portions between an open position and a closed position for grasping tissue therebetween. A guide member is configured for positioning between the proximal flanges of the jaw members. The guide member includes a tab extending transversely therefrom that is configured to operably engaged one of the first and second engagement portions to retain the jaw members in engagement with one another.

Abstract: A forceps includes an end effector assembly having first and second jaw members. Each of the jaw members includes a proximal flange extending therefrom. Each of the proximal flanges defines a bifurcated configuration having first and second spaced-apart flange components. The first flange component of the first jaw member is configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling. The first flange component of the second jaw member is configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling different from the first protrusion-aperture coupling. One or both of the jaw members is pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween.

Abstract: An electrosurgical instrument includes an end effector assembly including first and second jaw members. At least one of the first or second jaw members is movable about a pivot relative to the other from a spaced-apart position to an approximated position to grasp tissue between first and second opposed surfaces of the first and second jaw members, respectively. The electrosurgical instrument further includes an interface configured to provide a feedback related to a size of tissue grasped by the first and second jaw members. At least one of the first or second jaw members includes a touch sensor configured to sense a touch span where the tissue touches the at least one of the first or second opposed surfaces. The end effector assembly further includes an angle sensor configured to sense an angle α about the pivot between the first and second opposed surfaces.

Abstract: A forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to at least one of the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.
