Surgical instrument suitable for microinvasive surgery

摘要

The grip surfaces (9, 11) of the handles (8, 10) used to manipulate the instrument (1) are joined together at their free end by a bow-frame-shaped leaf spring (16) whose free ends extend parallel to these surfaces. A tube (2) and rod (3) are arranged coaxial to each other in the length direction of the instrument. Each of these two members has a work tool (4, 5) at its distal end and a handle at its proximal end, the handle having a grip surface parallel to and located on one side of the instrument length axis. The handles are used to pivot the two members relative to each other.
