Abstract: An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

Abstract: A surgical instrument configured to facilitate access to interior components thereof for cleaning and refurbishment purposes includes a housing assembly, an elongated shaft assembly and an end effector. The housing assembly includes an actuator, and the elongated shaft assembly includes an interior control member operatively coupled to the actuator. The elongated shaft assembly also includes outer cover including first and second cover members and a hinge coupling the first and second cover members to one another such that the outer cover may be selectively moved between a closed configuration wherein the interior control member is enclosed within the outer cover and an open configuration wherein the interior control member is exposed. The end effector is supported at a distal end of the elongated shaft assembly, and is operatively associated with the interior control member.

Abstract: A method of treating bowel diseases includes introducing a fluid into a portion of a patient's colon and applying energy thereto from an external energy source such that the fluid and the energy cooperate to treat tissue of the portion of the patient's colon in contact with the fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patient's colon, introducing an electrically-conductive fluid thereto, and energizing an electrode disposed therein to treat tissue of the portion of the patient's colon in contact with the electrically-conductive fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patient's colon and introducing a heated fluid at a temperature equal to or above 60° C. to treat tissue of the portion of the patient's colon in contact with the heated fluid.

Abstract: A forceps includes a drive assembly and an end effector assembly having first and second jaw members movable between a spaced-apart position, a first approximated position, and a second approximated position. The drive assembly includes a drive housing and a drive bar. The proximal end of the drive bar is coupled to the drive housing, while the distal end of the drive bar is coupled to at least one of the jaw members. The drive housing and the drive bar are selectively movable in conjunction with one another between a first position and a second position to move the jaw members between the spaced-apart position and the first approximated position. The drive assembly is selectively activatable to move the drive bar independent of the drive housing from the second position to a third position to move the jaw members from the first approximated position to the second approximated position.

Abstract: An ultrasonic surgical instrument includes a transducer assembly having a distal engagement member and configured to supply ultrasonic energy. A waveguide defines a longitudinal axis and has a proximal engagement member configured to threadingly engage the distal engagement member. The waveguide is configured to transmit the ultrasonic energy therealong to a distal end thereof for treating tissue. A torque member is coupled to the transducer assembly and is disposed about the longitudinal axis. The torque member is selectively rotatable about the longitudinal axis and relative to the waveguide to threadingly engage the transducer assembly and the waveguide to one another. The torque member includes a plurality of fingers pivotably coupled thereto and movable between a closed position and an open position. In the open position, each finger extends substantially perpendicularly from the longitudinal axis to define a moment arm that facilitates the engagement of the transducer assembly and the waveguide.

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 provides a bipolar forceps. The bipolar forceps includes a housing having a handle assembly including a movable handle and one or more shafts. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. A solenoid is in operative communication with the movable handle and operatively couples to a drive rod operatively coupled to at least one of the first and second jaw members for causing movement thereof. One or both of the first and second jaw members includes one or more teeth configured to engage one or more teeth located on the drive rod such that rotation of the solenoid imparts one of longitudinal and rotational movement of the drive rod such that at least one of the first and second jaw members moves between the open and closed positions.

Abstract: An electrosurgical forceps is provided with a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly includes a pair of first and second jaw members pivotably coupled to one another via a pivot pin. One or both of the first and second jaw members may be movable from an open position for positioning tissue therebetween to a clamping position for grasping tissue. A detent is operably disposed proximal the pivot pin and extends radially outward from a proximal flange of one of the jaw members. The detent is configured to releasably engage a corresponding slot disposed on a proximal flange of the other jaw member. The detent and slot are configured to control a gap distance between the first and second jaw members when the first and second jaw members are in the clamping position.
