  • Patent number: 6482153
    Abstract: A illuminated surgical retractor for illuminating a subcutaneous surgical field in the space between a vessel, such as the saphenous vein, and the subcutaneous tissue when the illuminated retractor is used to retract the subcutaneous tissue away from the superior surface of the vessel, the illuminated surgical retractor having a handle connected at an acute angle to a distal end of a first blade section, a second blade section that is connected, and substantially co-planer, to the first blade section, a distal end of the second blade section defining an illumination input end, a connector coupled to the illumination input end so that a source of illumination can be optically coupled, via the connector, to the illumination input end so that the second blade section is substantially illuminated, and, alternatively, a bent tip extending from the proximal end of the first blade section to aid in the required dissection of the intervening tissue.

  • Patent number: 4076361
    Abstract: The remote, manipulator, attachable, connector apparatus includes telescoping outer and inner connector units, one of which preferably the outer one, has on the end thereof remote from the other connector unit an elbow portion laterally extending therefrom which preferably can be swiveled and locked and in any position in a plane transverse to the longitudinal axis of the assembly. The latter connector unit has exposed preferably on opposite diametrically sides thereof a pair of outwardly, spring-urged, depressible members having operating, brightly colored latch members adapted to interlock with the other connector unit when the depressible members are in their outermost positions. If the depressible members are released, as the connector units are moved fully into telescoping relation, the latch members slide along raised surfaces of the other connector unit where they are readily visible.
