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.

An electrosurgical smoke evacuation pencil includes a handle housing having a proximal end portion and a distal end portion, the handle housing defining a first lumen therethrough. The electrosurgical pencil also includes a nozzle disposed within the first lumen and defining a second lumen, the nozzle being movable relative to and within the handle housing and extending proximally past the proximal end portion of the handle housing. The electrosurgical pencil may further include a swivel connector coupled to the distal end portion of the handle housing, the swivel connector configured to couple to a suction source. The electrosurgical pencil includes a hub assembly securedly disposed within the second lumen, the hub assembly including a conductive tube configured to couple to a source of electrosurgical energy, and an electrode slidably disposed within the conductive tube, the electrode being movable relative to and within the conductive tube.

A surgical instrument includes a housing having a shaft extending distally therefrom, an end effector assembly disposed at a distal end of the shaft, a handle assembly coupled to the housing for manipulating the end effector assembly, a deployable assembly, at least one actuator for deploying and retracting the deployable assembly, and a closure member. The closure member is keyed to the actuator(s) and operably positioned relative to the movable handle of the handle assembly such that, upon rotation of the actuator(s) relative to the housing from an un-actuated position to an actuated position, the closure member is urged into contact with the movable handle to urge the movable handle from an initial position to a compressed position, thereby moving the end effector assembly to an approximated position.

Gear assembly for surgical instruments

A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity. A gap-setting gauge is grasped between the first and second jaw members to define a gap-distance between the jaw members equivalent to a thickness of the gap-setting gauge. The first and second jaw members are set such that the jaw members are prevented from approximation beyond the gap-distance.

Surgical instrument having a bipolar end effector assembly and a deployable monopolar assembly

A deployment and retraction mechanism for a surgical instrument includes a gear box defining a longitudinal slot, a slider, a ring gear, and a planet gear. The slider is configured to engage a deployable component of the surgical instrument and is translatable along the longitudinal slot between a proximal end, corresponding to a storage condition of the deployable component, and a distal end, corresponding to a use condition of the deployable component. The planet gear is operably engaged with the ring gear and configured to orbit within the ring gear. The planet gear includes an off-center pin rotatably supporting the slider thereon. The planet gear and ring gear are configured such that a one-half orbit of the planet gear within the ring gear translates the slider from one end of the longitudinal slot to the other end of the longitudinal slot.

A surgical instrument includes a housing, a rotating assembly including a rotation wheel coupled to the housing, a shaft engaged with the rotation wheel within the housing and extending distally from the housing, an end effector assembly disposed at a distal end of the shaft, a drive assembly slidably disposed within the shaft and operably coupled to the end effector assembly for manipulating the end effector assembly, a knife assembly slidably disposed within the shaft translatable relative to the end effector assembly between a retracted position and an extended position, an elongated insulative sheath slidably disposed about the shaft, and an energizable member slidably disposed within the shaft. The instrument is configured such that rotation of the rotation wheel relative to the housing similarly rotates the shaft, end effector assembly, drive assembly, knife assembly, elongated insulative sheath, and energizable member relative to the housing.

A deployment and retraction mechanism for deploying and retracting a deployable component of a surgical instrument includes a gear assembly, a slider, and one or more actuators. The slider is translatable between a proximal position, corresponding to a storage condition of the deployable component, and a distal position, corresponding to a use condition of the deployable component. The actuator(s) is coupled to the gear assembly and is movable from an un-actuated position to an actuated position. The gear assembly is configured such that a full actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to the other of the proximal or distal positions while a partial actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to an intermediate position and back to the one of the proximal or distal positions.

An electrosurgical forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The forceps also includes a switch assembly that includes a supporting member, a flexible membrane circuit having snap dome switch contacts operably fixed thereto, and ergonomically-contoured keytops. The switch assembly provides at least one monopolar activation switch, and a bipolar activation switch. The forceps also include a drive mechanism which causes the jaw members to move relative to one another for manipulating tissue. A monopolar safety switch is incorporated into the switch assembly which cooperates with the drive mechanism to inhibit the monopolar activation switch when the jaw members are in an open position.

Switch assembly for electrosurgical instrument

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.
