Assignee:

Circon Corporation - Santa Barbara CA

International Classification:

A61B 1739

US Classification:

606 41

Abstract:

A shaped conductive core electrode member having an elongated curved sharp leading cutting edge forming part thereof for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member having a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator. The second end terminates in an electrode support member which is operatively connected to or forms an integral part of the shaped electrode as an active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core. The bifurcated arm is covered with an insulative material except at the distal end where the shaped electrode is located. The electrode support member includes the shaped electrode having a sharp leading cutting edge and an opening extending therethrough for rigidly operatively mounting the shaped conductive core electrode member on the conductive core of the support member.

Assignee:

Circon Corporation - Santa Barbara CA

International Classification:

A61B 1736

US Classification:

606 14

Abstract:

A sheath is provided having a tube and a latch receptacle for removably connecting the sheath with a cooperating working element. The latch receptacle is static and has means for receiving at least a portion of a movable latch of the working element such that the latch receptacle can be disconnected from the working element without touching the sheath. A continuous flow resectoscope sheath assembly may also be provided with both an inlet post and an outlet post on the outer sheath portion.

Circon Corporation - Santa Barbara CA

International Classification:

A61B 100

US Classification:

128 4

Abstract:

A continuous flow hysteroscope is shown. The hysteroscope includes an outer sheath having an outer surface, an inner surface and a hollowed-out central area extending along a central axis which extends therethrough. The outer sheath has a proximal section and a distal section. The distal end includes a plurality of openings communicating between the outer surface and inner surface. The openings have a predetermined shape and pass fluid exterior to the distal section therethrough and into the hollowed-out central area. The proximal section of the outer sheath includes an outlet and an inlet. An inner member is positioned within the hollowed-out central area and includes a first channel which is adapted to receive a telescope. A second channel, which is substantially parallel to the first channel is utilized for passing a working tool. The first and second channel are operatively coupled to an inlet for passing fluid therethrough and out of the distal end outer sheath.

Circon Corporation - Santa Barbara CA

International Classification:

A61B 1736

US Classification:

606 46

Abstract:

A system for reducing drag in a resectoscope working element. A hole is provided at a proximal end of a substantially enclosed electrode sheath for exiting fluids and substantially preventing pressure from being generated in the sheath. A working element has a guide block with a guide bar channel having a first cross-sectional shape and a guide bar with a second cross-sectional shape such that there are spaces between the guide bar and the guide bar channel and the bearing surfaces therebetween are relatively small.

US Classification:

606 46

Abstract:

A grooved slider forming part of an electrode for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member. The elongated conductor member has a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator and the second end terminates in an active member. An electrode support member is operatively connected to the active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core spaced a predetermined distance from the active member. The bifurcated arm is covered with an insulative material except at the distal end where the grooved slider is located. The electrode support member has a grooved slider having at least one sloping leading edge surface and protrusions forming areas of increased current densities fixedly mounting the grooved slider on an electrode support member. A method for treating and vaporizing tissue, such as prostate tissue, using the grooved slider electrode for a resectoscope is also shown.

Circon Corporation - Goleta CA

International Classification:

A61B 100

US Classification:

600105

Abstract:

A resectoscope with a working element and an electrode. The working element has a movable actuator assembly with a receiving area for receiving a proximal end of the electrode. The receiving area has an entrance, a plug area, and a curved section between the entrance and the plug area. The electrode has a proximal end with a connection section for connection to an electrical plug connector in the plug area. The proximal end also has a flexible section next to the connection section. The flexible section resiliently deforms along the curved section of the receiving area in the actuator assembly.
