Abstract: An end effector assembly having first and second jaw members is provided where one or both of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes an inwardly-facing surface having a slot defined therein and a wire having an insulative coating. A seal plate has at least one protrusion that is configured to be disposed in the slot. The at least one protrusion of the seal plate is configured to displace the insulative coating from the wire thereby forming an electrical connection therewith when the at least one protrusion is disposed in the slot.

Abstract: A surgical instrument includes a housing, an end effector and an elongated shaft extending therebetween. The end effector is movable between open and closed configurations. The elongated shaft includes a distal portion that is movable between aligned and articulated configurations. The surgical instrument further includes a driving assembly that induces motion in the end effector between open and closed configuration and maintains a closure pressure in the range of about 3 kg/cm2 to about 16 kg/cm2 between aligned and articulated configurations of the elongated shaft.

Abstract: A forceps 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 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.

Abstract: A surgical system includes a surgical instrument, a motion sensor, and a computing device. The surgical instrument includes a housing, an end effector assembly distally-spaced from the housing, and a movable component movable relative to the housing. The motion sensor is disposed on or within the housing and configured to sense a vibration signature associated with movement of the movable component relative to the housing. The computing device communicates with the motion sensor, is configured to receive the vibration signature therefrom, and is configured to determine a condition of the movable component based on the vibration signature. A method of monitoring a surgical instrument includes sensing a vibration signature generated from movement of a movable component of a surgical instrument relative to a housing of the surgical instrument, and determining, based on the sensed vibration signature, a condition of the movable component.

Abstract: An endoscopic instrument is provided and includes a housing including an elongated shaft assembly extending distally therefrom. The elongated shaft assembly includes inner and outer shaft members. The inner and outer shaft members are removably coupled to the housing and the outer shaft member is movable with respect to the inner shaft member. An end effector is operably supported at the distal end of the outer shaft member and includes a pair of jaw members configured for treating tissue. A bushing operably couples to the inner and outer shaft members of the shaft assembly and selectively and releasably couples to the housing. The bushing includes one or more mechanical interfaces configured to engage one or more slots defined through the inner shaft member and one or more slots defined through the outer shaft member to release the inner and outer shaft members from the housing.

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 forceps includes an end effector assembly having first and second jaw members. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes an opposed jaw surface having an electrically-conductive tissue sealing plate disposed thereon. The electrically-conductive tissue sealing plate includes a first portion configured to conduct energy through tissue grasped between the jaw members to create a main tissue seal and a second portion including a plurality of spaced-apart fingers extending from the first portion. The second portion is configured to conduct energy through tissue grasped between the jaw members to create an auxiliary tissue seal extending from the main tissue seal for reducing stress concentrations adjacent the main tissue seal.
