Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
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.
Claim 2
Dependent Claim
133 words
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.
Claim 3
Dependent Claim
23 words
The coagulation forceps according to claim 1, characterized by the fact that at least the opposed surfaces of the insulation-free parts are flat.
Claim 4
Dependent Claim
84 words
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.
Claim 5
Dependent Claim
29 words
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.
Claim 6
Dependent Claim
36 words
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.
Claim 7
Dependent Claim
58 words
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.
Claim 8
Dependent Claim
47 words
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.
Claim 9
Dependent Claim
20 words
The coagulation forceps according to claim 7, further characterized in that the actuating sleeve is flared at the distal end.
