摘要： An improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector is capable of different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a trigger mechanism contained within the handle. In some embodiments, the end effector includes a pair of curved jaw members and blade assembly having a cutting blade at its distal end. The trigger mechanism drives blade assembly longitudinally within the elongate shaft such that the cutting blade protrudes between the jaw members. To help the trigger mechanism push the blade assembly around the curved jaws, the distal end of blade has a graduated flexibility that easily bends to the shape of the jaw members. The distal end of the blade may also be provided with a low friction coating so that it can easily slide between the jaw members.

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： A switch mechanism includes a housing with a fenestration, a switch element held in the housing, and a first tab and a second tab each being pivotally attached to an opposite lateral edge of the fenestration. The tabs are constrained to rotational movement relative to the housing so that contact with the first tab or the second tab causes the respective tab to rotate to actuate the switch element.

摘要： An electrosurgical instrument includes a housing, a shaft extending from the housing, and an end effector assembly attached at a distal end of the shaft. A handle assembly is coupled to the housing and includes a movable handle for manipulating the end effector assembly. An outer sleeve is disposed about the shaft and selectively translatable relative thereto. An energizable member is operably coupled to the outer sleeve. A deployment mechanism is provided including a lever rotatably coupled to the housing and positioned proximally of the movable handle and at least one link member coupled between the lever and the outer sleeve. The link member(s) couple to the outer sleeve distally of the movable handle. Rotation of the lever translates the outer sleeve distally to move the outer sleeve over the end effector assembly and simultaneously deploy the energizable member distally past the end effector assembly.

摘要： The present disclosure is directed to electrode assemblies, and specifically to struts comprising electrode assemblies and electrodes contained on the struts. The electrode assembly struts are constructed to have a low profile and to have superior strength over the length of the strut such that an electrode assembly including the strut is highly resistant to radial compression. The electrodes included on the low profile, high strength strut also is designed to have a reduced profile such that electrode assemblies including the strut and electrode can easily be used with 6 French and smaller guide catheter assemblies.
