摘要:
An ultrasonic-surgical-shears tissue pad has a tissue-pad body including a base material and at least one filler material. An alternate ultrasonic-surgical-shears tissue pad has a tissue-pad body having adjoining first and second regions, wherein the first region includes a first material and wherein the second region includes a second material. An ultrasonic surgical shears includes an ultrasonic surgical blade and a clamping arm which is operable to open and close toward the blade and which has a transversely and resiliently flexible distal tip. An alternate ultrasonic surgical shears includes an ultrasonic surgical blade, a clamping arm operable to open and close toward the blade, and a tissue pad attached to the clamping arm and having a clamping surface, wherein at least a portion of the tissue pad is resiliently flexible in a direction substantially perpendicular to the clamping surface.

Various embodiments are directed to surgical instruments for use in handheld applications or with robotic surgical systems. The surgical instruments may comprise an end effector to treat tissue and a shaft extending proximally from the end effector along a longitudinal axis. Some embodiments may be usable with an instrument mounting portion of a robotic surgical instrument. For example, the shaft may extend proximally to the instrument mounting portion. The device can comprise first and second articulation cables (1306, 1308) transitionable between locked and unlocked states.

An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clamping forces and a force limiting mechanism that effectively smooths out abusive tissue forces. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural swing of the surgeon's thumb, whether gripping the surgical instrument right-handed or left handed.

A nested trigger assembly for a surgical instrument may generally comprise a first trigger and a second trigger, wherein the first trigger and the second trigger are movable together on a first stroke of the nested trigger assembly, wherein the second trigger is configured to be biased away from the first trigger after the first stroke and before a second stroke, and wherein the second trigger is configured to be moved toward to the first trigger during the second stroke. A surgical instrument may generally comprise a shaft comprising a proximal end and a distal end, a handle extending from the proximal end, wherein the handle comprises a gripping portion, and a nested trigger assembly extending from the handle. The nested trigger assemble may comprise one of a separable trigger assembly and a divisible trigger assembly.
