Abstract
Abstract ABSTRACT OF THE DISCLOSURE A device is disclosed for use in a laparoscopic tubal cauterization for blocking the fallopian tubes of a patient and comprises a substantially tubular body member having a piston slidably mounted therein; a spring urges the piston to a first position relative to the body member; a button extends from one end of the body member for moving the piston to a second position against the urging of the spring; first and second electrodes are incorporated for either monopolar or bipolar treatment of the living tissue; the first and second electrodes are disposed to grasp the living tissue when the piston is in the first position and to release the living tissue when the piston is in the second position; the invention includes a circuit breaker for terminating continuity when the piston is disposed in the second position and means for disabling an activating switch when the piston is in the second position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
185 words
A device for treating living tissue with an electric current from an electrical power source, comprising in combination: a body member; a piston slidably mounted relative to said body member; urging means for urging said piston to a first position relative to said body member; means for moving said piston to a second position relative to said body member against said urging means; a first and a second electrode element; means for mounting said electrode elements for movement in accordance with the movement of said piston; said first and second electrode elements disposed to grasp the living tissue when said piston is in said first position and disposed to release the living tissue when the piston is in said second position; and means for connecting said first and second electrode elements to the electrical power source to provide an electrical current flow relative to the living tissue; said connecting means including switch means mounted on said body member and means mounted on said piston cooperating with said switch means to allow said electrical current to flow only when said piston is in said first position.
Claim 2
Independent Claim
185 words
A device for treating living tissue with an electric current from an electrical power source, comprising in combination: a body member; a piston slidably mounted relative to said body member; urging means for urging said piston to a first position relative to said body member; means for moving said piston to a second position relative to said body member against said urging means; a first and a second electrode element; means for mounting said electrode elements for movement in accordance with the movement of said piston; said first and second electrode elements disposed to grasp the living tissue when said piston is in said first position and disposed to release the living tissue when the piston is in said second position; and means for connecting said first and second electrode elements to the electrical power source to provide an electrical current flow relative to the living tissue; said connecting means including switch means mounted on said body member and means mounted on said piston cooperating with said switch means to allow said electrical current to flow only when said piston is in said first position.
Claim 3
Dependent Claim
27 words
A device as set forth in Claim 1, wherein said means for moving said piston includes a button extending from a first end of said body member.
Claim 4
Dependent Claim
24 words
A device as set forth in Claim 2, wherein said first and second electrode elements extend from a second end of said body member.
Claim 5
Dependent Claim
15 words
A device as set forth in Claim 3, wherein said body member is substantially cylindrical.
Claim 6
Dependent Claim
19 words
A device as set forth in Claim 1, wherein said piston is integrally molded to contain said electrode elements.
Claim 7
Dependent Claim
24 words
A device as set forth in Claim 5, wherein said piston is slidably received in a sleeve extending from an end of said body.
Claim 8
Dependent Claim
22 words
A device as set forth in Claim 5, wherein each of said first and second electrode elements includes an in-wardly projecting tab.
Claim 9
Dependent Claim
31 words
A device as defined in Claim 1, including means for connecting said electrode elements to a same polarity of said electrical power source to provide monopolar treatment of said living tissue.
Claim 10
Dependent Claim
30 words
A device as defined in Claim 1, including means for connecting said electrode elements to different polarities of saicl electrical power source to provide bipolar treatment of said living tissue.
Claim 11
Dependent Claim
45 words
A device as in Claim 1, wherein said switch means is manually operable for completing, when operated, a circuit between said power source and said elements so that current flows only when said piston is in said first position and said switch means is operated.
Claim 12
Dependent Claim
104 words
A device as in Claim 14, wherein said switch means includes first and second contact members biased apart, an activator mounted in said body member positioned for engaging one of said contact members to move that member toward the other contact member and wherein said cooperating means includes an elevated region on said piston positioned for engaging said other contact member when said piston is in said first position to move said other contact member toward said one member so that when said region engages said other contact member and said activator engages said one contact member said contact members are in electrical connection.
