ABSTRACT:
The present invention is a novel surgical retractor used singularly or in pairs to provide optimum viewing exposure of the surgical field during open gallbladder and biliary tract surgery and to assist in the closing. This stainless steel device comprises a broad rectangular head portion, a narrow angular neck portion, a flat body portion and a flat tail portion disposed angularly relative to the central longitudinal axis of the body portion. The angular relationship between the tail portion and the central longitudinal axis of the body portion will be from about 20.degree. to about 30.degree. in one embodiment of the retractor and from about 75.degree. to about 95.degree. in a second embodiment of the retractor. The device is useful in a small incision thus reducing operation time and cost while improving patient safety and recovery time.
