International Classification:

A61B 132

US Classification:

600219, 600245

Abstract:

An illuminated rectal retractor for creating a working space for dissecting instruments in support of a surgical procedure such as rectal examination or for the removal of polyps or hemorrhoids or other types of procedures which require the illumination and access to tissue in the rectal area of a patient, the illuminated retractor having a handle member pivotally connected at an obtuse angle to a first cylindrical and elongate section and a second elongate section that is releasably connected to the first elongate section and a portion of the second elongate section defining an illumination input end portion which is optically coupled to a light source so that the second elongate section is substantially illuminated, and, an operating channel extends along the lengthwise dimension of the first elongate section and the operating channel is illuminated by the second elongate section in use.

International Classification:

A61M 1100

US Classification:

604 9301, 604 9903, 604264, 60416703

Abstract:

A port assembly adapted for insertion into the tissue of a patient during laparoscopic or endoscopic surgery wherein the port assembly includes an access port having a plurality of openings therein to allow for the insertion of multiple surgical instruments therethrough while maintaining a barrier to the flow of gas from the body cavity of the patient to the atmosphere. The access port is positioned in the housing of the port assembly and preferably includes two or more circular or semi-circularly shaped openings therein and a sealing member associated therewith to allow for the independent movement of the instruments therethrough.

US Classification:

600213, 600210, 600226, 600235, 600245, 600246

Abstract:

An illuminated deep pelvic surgical retractor for illuminating a surgical site and retracting tissue adjacent thereto, the illuminated surgical retractor having a handle member interconnected at an obtuse angle to a first elongate section and a second elongate section that is releasably connected to the first elongate section and a portion of the second elongate section defining an illumination input end portion which is optically coupled to a light source so that the second elongate section is substantially illuminated, and, a shield member is positioned adjacent to the distal end portion of the first elongate section to aid in directing light selectively from the second elongate section to the desired tissue or organ.

Filed:

Jul 21, 2005

Appl. No.:

11/186627

Inventors:

Robert Leonard - Suwanee GA, US

International Classification:

A61B 17/28

US Classification:

606205000

Abstract:

A surgical instrument handle including a base, a lever, and an actuator rod. The base defines opposed upper and lower faces, a proximal region, a distal region, an intermediate region, and a bend along the lower face at a transition from the intermediate region to the distal region. The lever defines a leading end, a trailing end, and opposed first and second major faces. The lever and the base are juxtaposed relative to each other, with the trailing end of the lever being pivotally connected to the proximal region of the base such that the lever pivots between an open position and a closed position. The rod includes a first end connected to the lever and a second end distal the base. With this configuration, a user grips the handle in a pistol grip-like fashion, with the bend promoting ergonomically correct handling.

International Classification:

A61B 1/313

US Classification:

600129

Abstract:

A surgical device and end effector connection system therefor include an easy-to-engage mechanism for connecting a handle/shaft/actuation rod unit to an end effector. This mechanism may utilize an axially engageable inner ball/socket inner connection with a threaded outer connection, or an inner bayonet connection with either an outer bayonet connection or an outer threaded connection. In each of the embodiments, an outer portion of the end effector preferably is statically engaged with the shaft, and an inner portion of the end effector is engaged with the actuation rod such that axial movement of the actuation rod can actuate a tool end of the end effector. The present invention further relates to methods of use for the laparoscopy device.
