Abstract: A surgical instrument is provided and includes a housing having a shaft. An end effector assembly operatively connects to the shaft and has a pair of first and second jaw members. A jaw insert is operably associated with the first and second jaw members. The jaw insert includes one or more cam slots defined therein configured to receive a cam pin that upon movement thereof rotates the first and second jaw members from an open position to a clamping position and an opening defined therein configured to securely house a pivot pin that provides a point of pivot for the first and second jaw members. The jaw insert is manufactured from an insulative medium to dielectrically isolate the first and second jaw members.

Abstract: The present disclosure is directed to a fluid cooled ultrasonic surgical instrument and related systems and methods of use therefor. In some embodiments, the disclosed ultrasonic surgical instrument is adapted for used within an insufflated cavity or pneumoperitoneum of a patient. The instrument includes a housing having an elongate shaft, a waveguide disposed at a distal end of the shaft, a coolant inlet port defined in an outer surface of the housing, and a coolant pump disposed within the housing and configured to move coolant from the coolant inlet port to the waveguide. During use, insufflation gas from within the pneumoperitoneum is drawn into the instrument shaft by the coolant pump, and blown over the waveguide to provide cooling. The delivery of ultrasonic energy and activation of the pump may be controlled by a processor in response to user input and waveguide temperature.

Abstract: An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.

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 surgical forceps includes a housing having a movable handle coupled thereto and movable between an initial position and a compressed position. A drive bar is operably coupled to the movable handle such that movement of the movable handle between the initial and compressed positions effects longitudinal translation of the drive bar. The drive bar further includes a coupling member disposed at a distal end thereof. An end effector assembly includes first and second jaw members movable between spaced-apart and approximated positions. Each jaw member defines a cam slot. A cam pin is slidably disposed within the cam slot of each of the jaw members. The coupling member is configured to releasably engage the cam pin such that movement of the movable handle between the initial position and the compressed position effects movement of the jaw members between the spaced-apart position and the approximated position.

Abstract: A forceps includes an end effector assembly having first and second jaw members movable relative to one another between a spaced-apart position, a first approximated position, and a second approximated position. One or both of the jaw members including a first stop member coupled thereto and disposed between the jaw members. The first stop member is longitudinally translatable along a surface of the at least one jaw member from a first position, wherein the first stop member inhibits approximation of the jaw members beyond the first approximated position, and a second position, wherein the first stop member inhibits approximation of the jaw members beyond the second approximated position.

Abstract: A surgical instrument includes a reusable base component including a handle and an electrically activatable modular component removably coupled to the base component. The modular component includes an end effector operable from the handle to treat tissue. The end effector is responsive to manipulation of the handle. A first energy storage component is disposed onboard the base component and is electrically coupled to a source of electricity. A second energy storage component is disposed onboard the modular component and is electrically insulated from the first energy storage component. The second energy storage component is arranged such that a current may be selectively induced in the modular component by delivery of electrical energy to the first energy storage component.

An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.
