Abstract

An ultrasonic soft tissue cutting and coagulation system has a movable ultrasonic probe member connected to a stationary clamp jaw. The probe member is movable between an open position, spaced from a tissue engaging surface of the clamp jaw, to a clamped position in which the probe member is moved toward the tissue engaging surface so as to capture tissue therebetween.

Claims

1. An ultrasonic instrument for cutting tissue, comprising:

a. an ultrasonic transducer for generating ultrasonic vibrations;

b. a probe member connected to said ultrasonic transducer for receiving ultrasonic vibrations therefrom; and

c. a stationary clamp jaw having a tissue engaging surface;

wherein said probe member is movably connected to said clamp jaw; and

wherein said probe member includes a cutting surface movable between an open position spaced from the tissue engaging surface of the clamp jaw, to a clamped position in which the cutting surface is moved toward the tissue engaging surface so as to capture tissue therebetween.

2. An ultrasonic instrument for coagulating tissue, comprising:

a. an ultrasonic transducer for generating ultrasonic vibrations;

b. a probe member connected to said ultrasonic transducer for receiving ultrasonic vibrations therefrom; and

c. a stationary clamp jaw having a tissue engaging surface;

wherein said probe member is movably connected to said clamp jaw; and

wherein said probe member is movable between an open position spaced from the tissue engaging surface of the clamp jaw, to a clamped position in which the probe member is moved toward the tissue engaging surface so as to capture tissue therebetween.
