ABSTRACT:
An endoscopic retractor instrument for retracting an internal structure is presented which permits atraumatic retraction. The instrument utilizes a pair of flat springs which have distal resilient engagement surfaces that are angularly displaced from the proximate regions of the springs such that the resultant restorting spring force acting on the distal region occurs in a different plane from the restoring spring force acting on the proximate region. The proximate regions are carried in fixed relationship to an extension member which is slideably carried by the housing. A pair of support links pivotally interconnect the distal regions of the flat springs and a resilient central support member has a distal end pivotally connected to the support links to form an engagement surface of enhanced bearing area. Upon extension from the housing, the proximate regions of the flat springs are internally biased to open the engagement surface while the distal region of the springs permit the engagement surface to resiliently support the internal structure.
