Abstract
Abstract A disposable electro-surgical handle in which a single electrode may be provided with different shapes at its respective ends, such as a blade and a ball. Either end of the electrode is insertable into the handle and is releasably secured therein. A spring loaded current conducting clip insures electrical contact with the electrode.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, an electrical conductor entering one end of said bore, a member slidably mounted in said bore and electrically connected to said conductor, means resiliently urging said member towards the other end of said bore, an electrode receivable in the other end of said bore, said electrode having an elongated insulated body having a conductor therein and extending beyond the ends of said body, both ends of said electrode conductor constituting both a surgical tool and a member engaging portion of the electrode conductor whereby said electrode may be reversed in said handle, and stop means limiting entry of said electrode into said bore, said stop means being spaced from the end of the electrode conductor a distance causing movement of said member against said resilient means upon full insertion of the electrode into said handle.
Claim 2
Dependent Claim
147 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, an electrical conductor entering one end of said bore, a member slidably mounted in said bore and electrically connected to said conductor, means resiliently urging said member towards the other end of said bore, an electrode receivable in the other end of said bore, said electrode having an elongated insulated body having a conductor therein and extending beyond the ends of said body, both ends of said electrode conductor constituting both a surgical tool and a member engaging portion of the electrode conductor whereby said electrode may be reversed in said handle, and stop means limiting entry of said electrode into said bore, said stop means being spaced from the end of the electrode conductor a distance causing movement of said member against said resilient means upon full insertion of the electrode into said handle.
Claim 3
Dependent Claim
140 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, said bore having a transaxial shoulder at one enD of said bore, an electrical conductor entering said one end of said bore, a radially enlarged detent receiving means, comprising a circumferential groove, at the other end of said bore, a first electrically conductive member seated in said bore against said shoulder and connected to said conductor, a second electrically conductive member slidably mounted in said bore and axially spaced from said first conductive member, resilient means interposed between said first and second members and mechanically and electrically connecting said members, said resilient means including a spring operatively connected to said members, said first and second members having a generally C-shaped cross-sectional configuration, and each said member having a flange which faces the flange of the other said member.
Claim 4
Dependent Claim
140 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, said bore having a transaxial shoulder at one enD of said bore, an electrical conductor entering said one end of said bore, a radially enlarged detent receiving means, comprising a circumferential groove, at the other end of said bore, a first electrically conductive member seated in said bore against said shoulder and connected to said conductor, a second electrically conductive member slidably mounted in said bore and axially spaced from said first conductive member, resilient means interposed between said first and second members and mechanically and electrically connecting said members, said resilient means including a spring operatively connected to said members, said first and second members having a generally C-shaped cross-sectional configuration, and each said member having a flange which faces the flange of the other said member.
Claim 5
Dependent Claim
244 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, said bore having a transaxial shoulder at one end of said bore, an electrical conductor entering said one end of said bore, a radially enlarged detent receiving means, comprising a circumferential groove, at the other end of said bore, a first electrically conductive member seated in said bore against said shoulder and connected to said conductor, a second electrically conductive member slidably mounted in said bore and axially spaced from said first conductive member, said resilient means interposed between said first and second members and mechanically and electrically connecting said members, an electrode receivable in said other end of said bore, said electrode having an elongated insulated body having a conductor therein and extending beyond the ends of said body, one end of said electrode engaging said second member and the other end of said electrode conductor constituting a surgical tool, both ends of said electrode constituting both a surgical tool and a member engaging portion of the electrode conductor whereby said electrode may be reversed in said handle, stop means on said electrode limiting entry of said electrode into said bore, said stop means being spaced from the end of the electrode conductor a distance causing movement of said second member against said resilient means upon full insertion of the electrode into said handle, said electrode being provided with a radially extending detent engageable in said radially enlarged detent receiving groove.
Claim 6
Dependent Claim
244 words
An electro-surgical device including an elongated insulated handle having a bore therethrough, said bore having a transaxial shoulder at one end of said bore, an electrical conductor entering said one end of said bore, a radially enlarged detent receiving means, comprising a circumferential groove, at the other end of said bore, a first electrically conductive member seated in said bore against said shoulder and connected to said conductor, a second electrically conductive member slidably mounted in said bore and axially spaced from said first conductive member, said resilient means interposed between said first and second members and mechanically and electrically connecting said members, an electrode receivable in said other end of said bore, said electrode having an elongated insulated body having a conductor therein and extending beyond the ends of said body, one end of said electrode engaging said second member and the other end of said electrode conductor constituting a surgical tool, both ends of said electrode constituting both a surgical tool and a member engaging portion of the electrode conductor whereby said electrode may be reversed in said handle, stop means on said electrode limiting entry of said electrode into said bore, said stop means being spaced from the end of the electrode conductor a distance causing movement of said second member against said resilient means upon full insertion of the electrode into said handle, said electrode being provided with a radially extending detent engageable in said radially enlarged detent receiving groove.
