摘要： An end effector assembly of a forceps includes a first jaw with a tissue sealing surface and an electrode on the sealing surface, and a second jaw with a tissue sealing surface and an electrode on the sealing surface. The first jaw and the second jaw move between an open position and a closed position. The sealing surface of at least one of the first jaw and the second jaw has a rigid medial section and flexible lateral sections.

摘要： A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device

摘要： A surgical instrument includes an end effector, a shaft assembly, and an axial location feature. The end effector includes an ultrasonic blade and a clamp arm that can move between an open and closed position. The shaft assembly includes a proximal shaft portion, an acoustic waveguide extending proximally from the ultrasonic blade, a distal shaft portion extending along a distal axis, and an articulation section interposed between the proximal shaft portion and the distal shaft portion. The articulation section can deflect the distal shaft portion and the end effector relative to the longitudinal axis between a non-deflected position and a deflected position. The axial location feature can inhibit the ultrasonic blade from shifting relative to the clamp arm along the distal axis as the end effector is driven between the non-deflected position and the deflected position.

摘要： Forceps can include a drive pin, an outer tube, a first jaw, a second jaw, and an inner shaft. The outer tube can extend along a longitudinal axis. The first jaw can be pivotably connected to the outer tube. The first jaw can include a first flange that can be located at a proximal portion of the first jaw. The first flange can include a first chamfered edge configured to limit extension of the first flange laterally beyond an outer surface of the outer tube when the first jaw is in a closed position. The inner shaft can be located within the outer tube and can extend along the longitudinal axis.

摘要： A forceps having at least a first jaw with a longitudinal axis is disclosed. The first jaw can include a body portion, a first flange, a second flange and a cam pin. The first flange can define a first cam slot with a longitudinal extent along the longitudinal axis. The second flange can be spaced from the first flange a distance transverse to the longitudinal axis of the first jaw and can have a second cam slot. The cam pin, with a longitudinal axis, can be moveably secured within the first cam slot and the second cam slot. A diameter of the cam pin can be less than a width between a first longitudinal edge that defines a first side of each of the first cam slot and the second cam slot and a second longitudinal edge that defines a second opposing side of each of the first cam slot and the second cam slot so that the cam pin is moveably received by both the first cam slot and the second cam slot. With the first jaw pivoted to at least a first position, the cam pin and first flange can be configured such that the first longitudinal edge is contacted by the cam pin but the second longitudinal edge is spaced from the cam pin. The cam pin and second flange can be configured such that the first longitudinal edge is spaced from the cam pin but the second longitudinal edge is contacted by the cam pin.

摘要： An ultrasonic instrument comprises a body, a shaft assembly, an ultrasonic blade, and a pivoting member. The shaft assembly extends distally from the body. The ultrasonic blade is positioned distal to the shaft assembly. The pivoting member is pivotable with respect to the blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the blade. One or both of the shaft assembly or the pivoting member comprise a guide feature. The guide feature is configured to provide lateral alignment of the distal portion of the pivoting member with the blade as the pivoting member is pivoted to the closed position.

摘要： An instrument (10) that comprises a cartridge seat (24) for a knife cartridge (25). The knife cartridge (25) holds a knife (30), preferably in protected safe position in which the blade (32) of the knife (30) is reliably retained inside the housing (26) of the knife cartridge (25) during non-use, particularly if the knife cartridge (25) is not inserted in the sealing instrument (10). This concept leads to increased handling safety for the medical staff.
