Abstract
An electrosurgical probe comprises an elongate probe body having a surgical hook at a distal end thereof. A paddle element is reciprocatably mounted within the distal tip of the elongate body so that it can be shifted between an extended position where it covers the hook tip and a retracted position where it leaves the hook tip exposed. The paddle thus can cooperate with the hook in tissue dissection, clean the hook, as well as provide an alternate electrosurgical probe tip for use in electrosurgical procedures.
Claims25
An electrosurgical probe comprising:
- an elongate body having a proximal end and a distal end, wherein said body is electrically conductive along its length;
- a surgical hook electrically coupled to the distal end of the elongate body;
- a paddle element electrically coupled to the distal end of the elongate body;
- means for mounting the surgical hook and paddle element to reciprocate relative to each other, whereby the hook or the paddle element can be exposed and the relative movement can clean adherent debris;
- an electrical connector electrically coupled to hook and paddle element and disposed near the proximal end of the elongate body;
- and
- an electrically insulating cover on the body near the proximal end.

An electrosurgical probe comprising:
- an electrically conductive tubular sleeve having a proximal end, a distal end, and a lumen extending between said proximal and distal ends;
- an electrically conductive surgical hook attached to the distal end of the tubular sleeve;
- a paddle element reciprocatably mounted within the distal end of the lumen and disposed to slide past at least one side of the surgical hook;
- means for reciprocating the paddle element between a retracted position inside the lumen and an extended position which covers the hook;
- an electrical connector electrically coupled to the surgical hook and paddle element and disposed near the proximal end of the tubular sleeve;
- and
- an electrically insulating cover on the sleeve near its proximal end.

An electrosurgical probe comprising:
- an electrically conductive tubular sleeve having a proximal end, a distal end, and a lumen extending between said proximal and distal ends;
- an electrically conductive surgical hook attached to the distal end of the tubular sleeve and disposed to project distally from the lumen thereof;
- an electrically conductive shaft having a proximal end and a distal end, and being slidably received in the lumen of the tubular sleeve;
- a paddle element attached to the distal end of the shaft and disposed to slide past the surgical hook;
- means for reciprocating the shaft so that the paddle element may be shifted between a retracted position inside the lumen and an extended position which covers the surgical hook;
- an electrical connector electrically coupled to the surgical hook and paddle element and disposed near the proximal end of the shaft;
- and
- an electrically insulating cover on the tubular sleeve near the proximal end.

An electrosurgical method comprising:
- introducing an electrosurgical probe to an internal body location through an access tube;
- selectively engaging either a first electrode surface or a second electrode surface on the probe against tissue or other body structure;
- and
- passing current simultaneously through both electrodes of the probe to effect severing or cauterization by the engaged electrode surface;
- wherein the first electrode surface is a paddle, and wherein the method further comprises selectively retracting the paddle within the electrosurgical probe prior to engaging the second electrode surface which is a surgical hook against tissue or other body structure.

An electrosurgical method comprising:
- introducing an electrosurgical probe to an internal body location through an access tube;
- selectively engaging either a first electrode surface or a second electrode surface on the probe against tissue or other body structure;
- passing current simultaneously through both electrodes of the probe to effect severing or cauterization by the engaged electrode surface;
- and
- moving the first electrode surface past the second electrode surface to effect a shearing action to clean the electrode surfaces while the probe remains in the internal body location.

An electrosurgical probe for use with a power supply, the electrosurgical probe comprising:
- an outer elongate body having a proximal end, a distal end, and a lumen extending between said ends, wherein at least a portion of the distal end of the body is electrically conductive and defines an exposed electrode surface;
- an inner elongate member reciprocatably mounted in the lumen of the outer elongate body, said inner elongate member having a proximal end and a distal end, wherein at least a portion of the distal end of the member is electrically conductive and defines an exposed electrode surface;
- a handle disposed at the proximal ends of the body and member;
- means on the handle for reciprocating the body relative to the member;
- and
- an electrical connector on the handle which connector is electrically coupled to the electrically conductive portions of both the body and the member for connection to the power supply.
