摘要： 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 6 mm. 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.

摘要： A composite end effector for an ultrasonic surgical instrument is provided and includes a first portion formed from a first material that exhibits a first characteristic value when excited by an ultrasonic energy input and a second portion formed from a second material that exhibits a second characteristic value when excited by the ultrasonic energy input. The composite end effector exhibits a composite characteristic value different from the first and second characteristic values when excited by the ultrasonic energy input.

摘要： An ultrasonic surgical shears has a bifurcated ultrasonic surgical blade, a clamping arm and a substantially “T”-shaped tissue pad. An alternate ultrasonic surgical shears has an ultrasonic surgical blade, a clamping arm, and a tissue pad having first and second transverse outer portions and a movable transverse central portion. An ultrasonic surgical instrument has an ultrasonic surgical clamp including an ultrasonic member adapted to ultrasonically vibrate and has a surgical cutter distinct from the ultrasonic member. A method for sealing a blood vessel of a patient includes obtaining an ultrasonic surgical clamp, sealing the blood vessel with the ultrasonic member, and transecting the sealed blood vessel using the surgical cutter. An alternate method similarly transects patient tissue and seals a blood vessel therein. An ultrasonic-surgical-shears tissue pad includes first and second transverse outer portions which are more resiliently flexible than is a transverse central portion.

摘要： An ultrasonic surgical blade, and an instrument, having a gain step. The blade body has, in any half wave length of the ultrasonic-surgical-blade body, a first vibration antinode, a vibration node, a second vibration antinode, and a gain step. The gain step is located between the second vibration antinode and the first vibration antinode. The gain step is spaced apart from the vibration node by a gain-step distance greater than 5% of the distance between the second vibration antinode and the first vibration antinode. The instrument includes the blade, a handpiece having an ultrasonic transducer, and an ultrasonic transmission rod whose proximal end is operatively connected to the ultrasonic transducer and whose distal end activates the blade. In one option, the first vibration antinode is the distal tip, and the gain step is located between the vibration node and the distal tip, resulting in an increased active length of the blade.

摘要： A reducer seal which fits within the cannula handle of the trocar. Contained on the reducer seal there is a seal retainer. Contained on the seal retainer there is a track and movable on the track there is a slide. The reducer track is attached to the trocar housing. The reducer seal retainer is attached to the slide and holds the reducer seal in place. The reducer slide then snaps onto the reducer track. In an "open" position the reducer slide is held away from an opening in the reducer. Detents on the reducer track hold the reducer in this position. Transverse motion moves the reducer into an active or "closed" position. The reducer seal slides into frictional engagement on the sealing surface of the reducer track. The reducer has a smaller diameter opening than the trocar cannula.
