Abstract
A handle for a surgical instrument used in keyhole, endoscopic, and laparoscopic surgery, having a pivoting or articulated end portion and a mechanism for indexing the pivoting movement of the end portion. The indexing mechanism allows adjustment of the angle of the end portion for improved control and tactile feedback to the user. The handle also has a mechanism for locking and unlocking movement of the end portion whereby the end portion can be pivoted or articulated to a desired angle and the locking mechanism moved to a position to prevent movement of the end portion, thus holding it at the desired angle to achieve the improved control and tactile feedback to the user.
