Abstract: A surgical instrument having a body with a proximal end and a distal end, a working element, first structure for mounting the working element on the body for movement relative to the body between first and second positions, and second structure on the body for a) moving the working element selectively between the first and second position from a location remote from the working element and b) maintaining the working element in each of the first and second positions. The second structure includes an actuating element and third structure for mounting the actuating element on the body for movement relative to the body.

Abstract: A sealing structure for an elongate medical instrument. The sealing structure includes a first sealing member having a first body with oppositely facing first and second surfaces and a peripheral edge and a second sealing member having a second body with oppositely facing third and fourth surfaces and a peripheral edge. A housing has a peripheral wall to surroundingly engage the peripheral edges of the first and second bodies with the first and second sealing members in operative relationship, wherein the second surface on the first body facially abuts to the third surface on the second body. The first body has at least a first portion that is compressible and deformable, with the second body having at least a second portion that is likewise compressible and deformable. There is an opening in the first portion of the first body that extends through the first body from the first surface to the second surface.

Abstract: A quick release mechanism for detachably interconnecting a bronch tube with a laser micromanipulator. The bronch tube is provided with a channel aligned transversely to the tube axis and opening downwardly at an angle of approximately 45 degrees. The micromanipulator bracket includes a complementary pin adapted to receive the bronch tube channel thereon and to guide and position the tube in proper orientation. The micromanipulator bracket further includes an externally threaded barrel and bevelled locking nut which is threaded downwardly onto the bronch tube thereby locking the bronch tube against the bracket pin.

Abstract: Endoscopes employ an optical fiber cable connected to a light source to illuminate the viewing field. The adapter of the present invention facilitates connection of the optical fiber cable to the light source by accommodating a wide variety of differing cable connector sizes and types. The adapter has a channel-like frame mounted on the light source in front of the light. A cable holder with a downwardly opening notch is mounted on one flange of the frame. A spring biased cable support with an upwardly opening notch is mounted adjacent the cable holder so that the notches form an opening in which the connector may be engaged and retained in the adapter.
