A forceps includes first and second shafts each having a jaw disposed at a distal end thereof configured to rotate about a pivot to move the jaws between open and closed positions, the shafts defining a longitudinal axis therebetween. A knife deployment mechanism including a rack and pinion mechanism or a series of links is disposed within the first shaft and includes a trigger moveable along the longitudinal axis to deploy a knife between the jaws. A knife lockout is configured to move upon approximation of the first and second shafts between an engaged position preventing deployment of the knife and a disengaged position allowing deployment of the knife. A knife kickout mechanism is disposed within the first shaft in opposition to the second shaft and is configured to force the knife forward upon movement of the first and second shafts from an approximated position to a more open position.

A forceps includes shaft members each having a jaw member disposed at a distal end thereof and configured move the jaw members between open and closed position. A knife deployment mechanism includes a trigger moveable along a longitudinal axis to deploy a knife between retracted and extended positions between the jaw members, the knife deployment mechanism including links that cooperate to actuate the knife. A knife kickout mechanism is pivotably coupled to one link and is configured to engage a ramp disposed in a shaft member upon approximation of the shaft members, the knife kickout is configured to cooperate with the links to urge the knife back to an at rest position upon the opening of the shaft members.

An electrosurgical instrument includes a housing, a movable handle movable relative to the housing along an actuation path from an initial position to a grasping position to an activated position, an in-line activation switch disposed on the housing along the actuation path of the movable handle such that movement of the movable handle from the grasping position to the activated position activates the in-line activation switch, a trigger coupled the knife and movable relative to the housing from an un-actuated position to an actuated position, and a knife lockout operably associated with the movable handle and the trigger. The knife lockout is configured to inhibit actuation of the trigger from the un-actuated position to the actuated position until the movable handle reaches the activated position.

This disclosure is relative to the field of laparoscopic surgery and gynecologic surgery. Specifically disclosed is a surgical technique for laparoscopic hysterectomy and bilateral salpingectomy-oophorectomy which encompasses dissection and removal of the uterus, fallopian tubes, and ovaries. The technique utilizes a single-entry port located at the umbilicus in conjunction with access through the vaginal opening to access and manipulate the organs within the abdominal cavity.

A surgical clip applier comprising an electric motor system is disclosed. The electric motor system is configured to drive one or more drive systems of the surgical clip applier. The surgical clip applier comprises a control system configured to control the electric motor system. The control system is configured to monitor a parameter of the electric motor system to assess the operation of the one or more drive systems. In at least one instance, the control system monitors the electric current drawn by an electric motor and adapts the operation of the electric motor based on the electric current being drawn by the motor. The control system slows the electric motor down when the electric current drawn by the electric motor exceeds a threshold. The control system modulates the width, or duration, of voltage pulses applied to the electric motor to control the speed of the electric motor.

A surgical instrument includes an end effector and a housing mechanically coupled to the end effector. The end effector includes a first actuating device configured to perform a first surgical procedure and a second actuating device integrally associated with the first actuating device and configured to perform a second surgical procedure, the second surgical procedure being independently operable and different than the first surgical procedure. An outer portion of the first actuating device and an outer portion of the second actuating device form a portion of an outer housing of the end effector. The housing includes a first actuator, mechanically coupled to the first actuating device and configured to impart movement to the first actuating device and a second actuator, mechanically coupled to the second actuating device and configured to impart movement to the second actuating device.

Surgical tools are disclosed that include a first handle having a first recess, a second handle having a second recess, a first tip disposed in the first recess and extending distally, and a second tip disposed in the second recess and extending distally. The first tip has a first external surface and a first internal surface. The second tip has a second external surface and a second internal surface. The surgical tool has a first configuration wherein the surgical tool operates as forceps. The surgical tool has a second configuration wherein the surgical tool operates as scissors. The first internal surface can be moved adjacent to the second internal surface to permit rotation of the first tip relative to the first recess and permit rotation of the second tip relative to the second recess. The rotation of the first tip and the second tip transitions the surgical tool between the first configuration and the second configuration.

A surgical tool for performing telesurgical surgical operations such as cutting, shearing, grasping, engaging, or contacting tissue. The surgical tool comprises a pair of jaws cooperatively rotating open and close about an axis of rotation. The jaws further comprise one or more compliant electrodes electrically communicating with a conductor to deliver electrical energy to tissue engaged by the jaws. The electrodes formed of an elastomeric material impregnated with a conductive material or formed atop an elastomeric material allowing a certain amount of flexibility and thereby maintaining more consistent pressure on the tissue when the jaws engage the tissue.

A surgical instrument system is disclosed comprising a plurality of outputs driven by an input. The input is selectively engaged with the outputs by a shifting system.
