Auxiliary forceps for hand-assisted laparoscopic surgery (HALS)

摘要

Auxiliary forceps are provided for video-assisted minimally-invasive surgery, such as hand-assisted laparoscopic surgery, the forceps being intended for operation by a surgeon's non-dominant hand inserted through an incision for entering a patient's natural body cavity. The forceps comprises a plurality of actuating plates hinged elastically to one another and having a size and shape suitable for operation when held by the tips of two fingers. The forceps also has a plurality of jaws extending from each actuating plate, and a member for temporarily connecting the forceps to the surgeon's hand so as to maintain the forceps at an adjustable distance from the hand of not greater than a predetermined value. In addition, a structure is provided for housing the jaws relatively close to one another, within which the jaws are engaged during operation when the forceps is not in use.
