Abstract

A surgical, vascular coagulation forceps (1) comprising two mutually displaceable jaws (3, 4) bearing flat electrodes (12, 13) connected to different terminals of an hf source (16), or one of said jaws being fitted with an ultrasonic oscillator, characterized in that a coil unit (18) connected to an eddy current sensor (20) is mounted on at least one of the jaws (3, 4).

Claims

1. A surgical, vascular coagulation forceps (1) comprising:

two mutually displaceable jaws (3, 4) bearing flat electrodes (12, 13);

said flat electrodes (12, 13) being connected to different terminals of an hf source (16), or one of said jaws being fitted with an ultrasonic oscillator, and

wherein a coil unit (18) connected to an eddy current sensor (20) is mounted on at least one of the jaws (3, 4).

2. Forceps as claimed in claim 1, wherein the coil unit (18) is configured parallel to the gripping surface (8) of a jaw (3).

3. Forceps as claimed in claim 2, wherein the coil unit (18) encloses the electrode (12).
