摘要： 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.

摘要： 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.

摘要： An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
