【発明の名称】超音波手術器具用クランプ凝固/切断システム
Document Type and Number:
Japanese Patent JPH08505801
Kind Code:
A
Abstract:
An ultrasonic surgical apparatus includes an ultrasonic surgical instrument (10) having a handpiece (14) with a transducer for converting an electrical signal into longitudinal vibratory motion of a blade (20) connected to the handpiece and an accessory (12) releasably connected to the handpiece to enable clamping of tissue against the vibrating blade to afford improved coagulating and cutting of tissue. Scissors-like grips (26) actuate a pivoted clamp jaw (24) along one side of the ultrasonically vibrating blade (20) to compress and bias tissue against the blade in a direction normal to the direction of longitudinal vibratory movement. The clamp jaw and blade are rotatable relative to one another to align a selected blade edge of a multi-edged blade with the clamp jaw for cutting and coagulating while clamping or to circumferentially space a selected blade edge from the clamp jaw for cutting and coagulating without clamping.
