Abstract

Bipolar coagulation forceps in which the forceps coagulate both the fallopian tube and the adjacent mesoslpinx.

Claims

1. Bipolar frequency coagulation forceps for the coagulation of the Fallopian tubes, said forceps including two insulated current conductors affording a pair of resiliently spreading forceps arms which are closed by relative longitudinal shifting of an actuating sleeve accomplished with the aid of a handle, portions of the forceps arms located proximally to free ends of the conductors being insulated and each having a first curvature for closing the forceps by means of said sleeve, and having insulation-free second curvatures of less diameter than said first curvature located between said first curvature and said free end for clamping a Fallopian tube, and the free ends of the conductors being straight and insulation-free, adapted during the closing of the forceps to be placed approximately parallel to one another on opposite sides of the adjacent mesosalpinx.

2. The coagulation forceps according to claim 1, characterized by the fact that at least the opposed surfaces of the insulation-free parts are flat.

3. The coagulation forceps according to claim 2, further characterized by the conductors being contained within a tubular housing from which the forceps arms protrude, said housing being connected to an outer support shaft which supports one leg of a shear handle, and an actuating sleeve positioned concentrically between the housing and the support shaft, said actuating sleeve being connected to the other shear handle leg and having a distal end engageable with the proximal side of the insulated second curvature of the forceps arms.

4. The coagulation forceps according to claim 3, further characterized in that said one shear handle leg is connected by a strut to a coupling removably attached to the housing.

5. The coagulation forceps according to claim 4, further characterized in that the actuating sleeve is removably connected to the other shear handle leg and that a seal is provided between the actuating sleeve and the housing.

6. The coagulation forceps according to claim 4, further characterized in that the coupling part consists of a cylindrical housing provided with a transverse opening for receiving the housing and in which a spring-biased slide is located, said slide having a protuberance engaged with a recess in the housing, and said slide being manually depressable to disengage said protuberance.

7. The coagulation forceps according to claim 5, further characterized in that a bushing is located at the proximal end of the actuating sleeve for supporting an apertured end of the one shear handle leg and that a retainer is screwed to the threaded end of the bushing.

8. The coagulation forceps according to claim 7, further characterized in that the actuating sleeve is flared at the distal end.
