Abstract
An improved electrosurgical cutting device for connection to an electrosurgical generator has a non-conductive support member with a peripheral edge and a conducting member in the form of a wire electrode, distinct from the support member, disposed along at least a portion of the peripheral edge of the support member. The conducting member is electrically connected to an electrosurgical generator suitable for transmitting sufficient high frequency electrical energy to the conducting member, thereby enabling the conducting member to cut body tissue. The support member has a configuration that facilitates the manipulation of body tissue either with or without the presence of electrical energy at the conducting member.
Claims25
An electrosurgical cutting device for communicating electrically with an electrosurgical generator comprising:
- a non-conductive support member having a peripheral edge;
- and
- a conducting member, distinct from said support member, disposed along at least a portion of the peripheral edge of said support member, said conducting member configured to communicate electrically with the electrosurgical generator thereby allowing the electrosurgical generator to transmit sufficiently high frequency electrical energy to said conducting member to enable said conducting member to cut body tissue, wherein said conducting member forms a wire loop electrode with said support member filling the center of the loop.
An electrosurgical cutting device for communicating electrically with an electrosurgical generator comprising:
- a non-conductive support member having a peripheral edge wherein said support member is configured with a groove along at least a portion of the peripheral edge of said support member;
- a conducting member, distinct from said support member, disposed along at least a portion of the peripheral edge of said support member, wherein and said conducting member is seated in the groove;
- and
- an adaptable connector in electrical communication with said conducting member, said adaptable connector having a proximal and distal end, said support member extending from the distal end of said adaptable connector.
An electrosurgical cutting device for communicating electrically with an electrosurgical generator comprising:
- a handle having a proximal end and a distal end;
- a non-conductive, thermally stable support member extending from the distal end of said handle, said support member having a peripheral edge, said support member being configured to allow the manipulation of body tissue;
- a conducting member, distinct from said support member, extending from said handle and disposed along at least a portion of the peripheral edge of said support member, said conducting member configured to communicate electrically with the electrosurgical generator thereby allowing the electrosurgical generator to transmit sufficiently high frequency electrical energy to said conducting member to enable said conducting member to cut body tissue, wherein said conducting member forms a wire loop electrode with said support member filling the center of the loop.
An electrosurgical cutting device for communicating electrically with an electrosurgical generator comprising:
- a non-conductive support member having a peripheral edge;
- and
- a conducting member, distinct from said support member, disposed along at least a portion of the peripheral edge of said support member, said conducting member configured to communicate electrically with the electrosurgical generator thereby allowing the electrosurgical generator to transmit sufficiently high frequency electrical energy to said conducting member to enable said conducting member to cut body tissue, wherein a portion of said conducting member is internal to said support member.
