Abstract: A surgical instrument including housing having a shaft extending distally therefrom, an outer sleeve disposed about the shaft and selectively translatable relative to the shaft, a first drive shaft disposed within the shaft and translatable relative to the shaft independently of the outer sleeve, a second drive shaft disposed within the first drive shaft and coupled to the outer sleeve to translate in conjunction with the outer sleeve, and a rotatable nose wheel. The rotatable nose wheel is mounted about a distal end of the housing and is rotatably coupled to each of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft such that rotation of the rotatable nose wheel effects corresponding rotation of the outer sleeve, the shaft, the first drive shaft, and the second drive shaft in conjunction with one another and relative to the housing.

Abstract: A forceps includes an end effector assembly including first and second jaw members. One or both of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One or both of the jaw members is configured to conduct energy between the jaw members and through tissue grasped therebetween to treat tissue. An insulative tubular member is movable relative to the end effector assembly between a retracted position, wherein the insulative tubular member is positioned proximally of the end effector assembly, and an extended position, wherein the insulative tubular member is disposed about the end effector assembly. A monopolar member is configured to apply energy to tissue to treat tissue when the insulative tubular member is disposed in the extended 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: 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 sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.

Abstract: A surgical instrument includes a housing, an elongated shaft extending distally from the housing, an end effector assembly, and a trigger assembly. The trigger assembly is disposed in mechanical cooperation with the housing and is configured to longitudinally translate a drive member. The trigger assembly includes a trigger, a gear assembly, a spool, a slider, and a flexible drive member. The trigger is disposed in mechanical cooperation with the gear assembly. The flexible drive member is configured to engage the gear assembly, the spool, and the slider. Movement of the trigger with respect to the housing results in movement of the flexible drive member with respect to the housing and longitudinal movement of the slider with respect to the housing.

Abstract: A surgical instrument includes a housing, a handle, an elongated shaft, an end effector assembly, a drive assembly, a support, a roller, and an extension depending from the handle. The end effector assembly includes a first jaw member and a second jaw member. At least one of the jaw members is movable with respect to the other jaw member. The drive assembly includes a drive bar extending at least partially through the elongated shaft such that longitudinal translation of the drive bar causes movement of the jaw members. The extension includes a proximal surface and a channel defined therein. The proximal surface is configured to contact a portion of the drive assembly such that movement of the handle with respect to the housing causes longitudinal translation of the drive bar. The channel is positioned for mechanical engagement by the roller.
