A surgical retractor liner and integral drape suitable for inserting in an incision and adjusting in place to prevent cross-contamination during surgery between the incised cavity and the surrounding skin of the patient. In one embodiment, a flexible elastic liner impervious to microorganisms has resilient inner and outer rings at opposite ends for holding the liner firmly in the incision. The outer ring is rolled down over itself drawing the liner taut and contiguous in the incision. In another embodiment, a skirt is sealingly joined at the outer ring and tapers outwardly and sealingly joins to a drape around a central aperture therein. The inner ring is inserted and expanded against the inner edge of the incision, and the outer ring is rolled down over the liner and skirt to draw the liner taut in the incision and to retract the sides of the incision while positively anchoring the drape in place around the area of the incision. In another embodiment, a lengthwise incrementally and automatically adjustable wound protector and retractor is provided.

Surgical retractor and liner

Surgical apparatus for providing extracorporeal pneumoperitoneum. One embodiment provides a reversely turned fluid and gas impermeable fingerless sleeve ( ) with a quick connect and disconnect assembly around the cuff of the sleeve ( ) for sealing around an abdominal incision to allow hand-assisted minimally invasive surgery under conditions of pneumoperitoneum. A dome shaped enclosure ( ) is provided for use with the quick connect and disconnect assembly to seal around an abdominal incision and maintain pneumoperitoneum during interruptions in a surgical procedure. Another embodiment incorporates a fingerless sleeve ( ) which is adhesively secured directly to a patient's skin around an incision. The sleeve is applied over a pre-gloved surgeon's hand, and an outer surgical glove ( ) is applied over the sleeve ( ) in the region where the fingers and thumb protrude before the sleeve ( ) is reversely turned on itself for connection to a patient.

Surgical retractor liner appliance

Surgical apparatus for providing extracorporeal pneumoperitoneum. One embodiment provides a fluid and gas impremeable fingerless glove with a quick connect and disconnect assembly around the cuff of the glove which seals around an abdominal incision to allow hand-assisted minimally invasive surgery under conditions of pneumoperitoneum. Another embodiment provides a dome-shaped enclosure with the quick connect and disconnect assembly which seals around an abdominal incision to maintain pneumoperitoneum during interruptions in a surgical procedure.

A gun bore cleaning system comprising a cleaning patch guide and holder, and a solvent and patch collector. The guide includes a tube having a tapered bushing at its forward end for abutting the breech end of the bore opening, and an inclined patch support surface near a rearward end holds a cleaning patch. As a cleaning rod is passed through the tube into the bore, it captures the patch, impregnated with a cleaning solvent, and pushes it through the bore into the solvent and patch collector mounted on the muzzle of the gun where the patch and any excess solvent are retained. The solvent and patch collector includes an adaptor mountable on the muzzle and a disposable container removably connected to the adaptor.

Gun bore cleaning system

An improved surgical apparatus for hand-assisted minimum invasive surgery with isolation at the site of a wound from ambient conditions. A sleeve of gas-impermeable material includes entry and exit openings for access to the wound, and ports for introducing surgical instruments into the sleeve within easy reach of a surgeon's hand.

Surgical retractor liner and integral drape assembly

Apparatus and method for hand-assisted minimally invasive laparoscopic surgery which allows for palpation and biophysical feedback within a sterile environment. A sleeve provides a sealed chamber communicating with a wound accessible to an surgeon's hand through entry and exit openings. The entry opening is sealed around the surgeon's wrist or forearm by a cuff.

Apparatus and method for use in surgery

An incrementally adjustable apparatus and method of use thereof for protecting an incised wound from exposure to bacterial and other harmful contaminants. A pair of resilient O-rings is connected to opposite ends of an impermeable pliable sleeve. One of the O-rings is formed to engage the inner edge of the wound with a portion of the sleeve above the wound capable of being rolled onto the other ring to draw the remaining sleeve portion contiguous with the sides of the wound. Flat surfaces on the other ring provide a gripping surface to turn the ring about its annular axis.
