Abstract: A laparoscopic medical instrument for performing blunt dissection, as well as irrigation and aspiration of the operative field. The instrument comprises an elongated suction tube having proximal and distal ends, with the proximal end connected to a source of irrigation fluid and to vacuum suction equipment. A cannulated mandrel is partly inserted into the distal end leaving a portion of the mandrel extending outwardly from the elongated tube. A strip of cloth having a textured surface is wound around the outwardly extending portion of the mandrel for performing blunt dissection. An inner tube extends within the mandrel such that the bore of the inner tube is in registry with the bore of the elongated tube to provide a continuous internal bore extending through the entire instrument for supplying irrigation fluid and for removing the fluid and debris during aspiration. An X-ray opaque strip is wound within the cloth strip.

Abstract: An improved patient transfer sheet device includes a thin first sheet, having a low coefficient of friction for contacting inner surfaces thereof and substantially higher coefficients of friction for other surfaces contacting the first sheet, and a thin second sheet, fixedly connected to the first sheet. The device has a plurality of corner cuffs for releasably securing the device to a first supporting structure. A perforation, medially spaced lengthwise of a patient lying on the device, penetrates the first and second sheets such that the device can be divided and removed from under the patient without rolling or lifting the patient. A first modified transfer device provides a thin band having additional lengthwise perforations such that the device can be placed such that a patient can be transferred sidewise in a pre-selected direction and, subsequently, be transferred in the reverse direction.
Abstract: A new, lightweight reflective surgical drape which is effective in reducing the rate of heat loss in human patients during a variety of surgical procedures is disclosed. The drape comprises a core layer of non-conductive aluminum and a first and second adjacent layer of a thermoplastic material. A non-woven layer of absorbent material is attached to either the first or second adjacent layer of thermoplastic material.In a preferred embodiment, the drape of the present invention comprises a first layer of non-conductive aluminum and a second layer of a thermoplastic material. A third layer of non-woven absorbent material is attached to the first layer of non-conductive aluminum.
