Surgical instrument with actuator for adjusting shaft

摘要

The actuator (7) can be moved from its spring-loaded (10) forward position engaged with the shaft (1) to a withdrawn position at a distance from the shaft. In this withdrawn setting the shaft is released from the grip (3) by sliding the shaft out of its slide guide which otherwise joins it to the grip. The actuator consists of a swivel lever which engages the grip and pivots round axis (9) set horizontal and at right angles to the shaft length. The load spring is clipped in between the handle part (4) fitted to the proximal end of the grip and the actuator itself, and consists of two arms (13,16) held to the confronting inner sides (12,15) of the actuator and grip respectively in that one arm hangs in an opening (14) on the actuator side as against arm which is fixed adjustably on the other side.
