MICROSURGICAL HOLDING AND/OR CUTTING INSTRUMENT

摘要

A surgical handheld instrument for grasping an object includes two lever elements, each lever element having a grip portion and a jaw portion. A lever joint connects the two lever elements rotatably to each other between their grip portion and their branch portion. Each of the two grip portions is adjoined by a respective spring portion for connecting the two grip portions such that the two lever elements are held resiliently in an open position. To create an easily manageable, elegant and releasable connection for spring ends on surgical instruments, the handheld instrument includes a hinge pin at a free end of one spring portion and a bearing eye at a free end of the other spring portion. The bearing eye has a longitudinal slit for radial insertion of the hinge pin into the bearing eye.
