    Abstract: A surgical instrument includes a housing, a handle, an elongated shaft, an end effector assembly, a drive assembly, and an extension depending from the handle. The extension includes a proximal surface having a first proximal cam portion defining a first angle with respect to the longitudinal axis and a second proximal cam portion defining a second angle with respect to the longitudinal axis. Initial actuation of the handle from a non-actuated position causes the first proximal cam portion to contact the first portion of the drive assembly causing a first movement of the at least one jaw member, and a subsequent actuation of the handle causes the second proximal cam portion to contact the first portion of the drive assembly causing a second movement of the at least one jaw member.

    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: 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 surgical instrument includes an end effector assembly having jaw members movable between spaced-apart, first approximated, and second approximated positions. A knife is selectively movable relative to the end effector assembly between a retracted position, a first extended position, and a second extended position. A trigger is selectively actuatable between a un-actuated position, a first actuated position, and a second actuated position for moving the knife between its respective positions. A control member prevents movement of the trigger when the jaw members are disposed in the spaced-apart position, permits movement of the trigger to the first actuated position but prevents movement beyond the first actuated position when the jaw members are disposed in the first approximated position, and permits movement of the trigger to the second actuated position but prevents movement beyond the second actuated position when the jaw members are disposed in the second approximated position.

    Abstract: A surgical forceps including an end effector assembly has first and second jaw members. At least one of the first or second jaw members has a jaw frame defining a channel therein, an insulative member disposed within the channel of the jaw frame, and an electrically-conductive plate having a tissue contacting surface and at least one folded side portion. The insulative member includes a top portion having a tissue facing surface. The tissue contacting surface of the electrically-conductive plate is disposed on the tissue facing surface of the insulative member. The at least one folded side portion of the electrically-conductive plate is folded over the top portion of the insulative member such that the electrically-conductive plate conforms to a shape of the top portion of the insulative member.

    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.
