Abstract
A surgical instrument assembly includes a surgical instrument having a proximal handle (16) for control by the surgeon, the handle being ergonomically configured and having surface depressions (17, 18, 19, 20) to accommodate thumb and finger tips. The handle extends no more than about 5 cm beyond the point of grip so that the surgeon can rotate his/her hand over the end of the handle in unrestricted movement while maintaining the grip between thumb and middle finger. Improvements in the support means for the endoscope telescope and instrument shaft, as well as in the lighting system of the assembly are also disclosed, together with improvements in the mechanisms for moving a distal end of the instrument in the operating zone within a patient.
