Abstract
Bipolar forceps for grasping and coagulating tissue, are constructed so as not to damage the mesosalpinx fused with a fallopian tube, when carrying out uterine tube sterilisation by coagulation. To this end the forceps are provided with a first and a second jaw for gripping and holding the tissue to be coagulated, the first jaw having a recess at its distal end and a mandrel being provided on the second jaw, which mandrel protrudes into the recess in the first jaw with clearance, when the jaws are in a closed position. A region between the jaws, which accommodates the tissue to be coagulated is limited distally by the mandrel and proximally by a limb of a bar on the first jaw for engaging in the second jaw when the jaws are in their closed position.
Claims5
Bipolar forceps for grasping and coagulating tissue, the forceps having a proximal end and a distal end and comprising first and second jaws having at said distal end electrodes for gripping and holding tissue to be coagulated, the jaws being relatively movable between an open position and a closed tissue gripping position, the second jaw having a recess, the first jaw having an engaging bar extending toward and aligning with the recess of the second jaw, the recess permitting the engaging bar to engage the second jaw when the jaws are in their closed position, the first jaw having a distal recess and the second jaw having a mandrel extending toward and aligning with the distal recess of the first jaw, said distal recess permitting the mandrel to protrude therethrough and to engage the first jaw when the jaws are in their closed position, the jaws cooperating to define a region for receiving the tissue to be coagulated, said region being delimited distally by said mandrel and proximally by said bar.
