Medical instrument, particularly endoscopic instrument, has rotatable shaft, which runs in shank and has screw at its distal end, where screw meshes with gearing that is connected with jaw section

摘要

The medical instrument has a shank (2) and an instrument jaw (6), which is arranged at a distal end of the shank and has a pivoted jaw section (8). A rotatable shaft runs in the shank and has a screw at its distal end. The screw meshes with a gearing that is connected with the jaw section. The instrument jaw has another pivoted jaw section (10), which is connected with the gearing. The two jaw sections are pivoted about a common pivoting axis. The shaft is formed as a flexible shaft (16).
