Abstract
A laparoscopic instrument including a pair of handles pivotally rotatable among at least two lockable positions. The instrument includes two drums attached to respective ones of the handles, a tool drum coupled to one of the drums, and a shaft passing through apertures formed in each of the drums and the tool drum. The drums are rotatable around the shaft to cause the handles to be rotated among the lockable positions. The shaft includes a pair of winglets disposed along a length of the shaft. A push-button is connected to an end of the shaft to slide the shaft relative to the three drums. When the push-button is depressed, the winglets lock the handles together, allowing them to freely rotate about the shaft. When the push-button is released, pins secure one of the drums to a housing to allow rotation of one of the handles relative to the other.
