Abstract
The disclosed invention relates to an improvement in a surgical therapeutic instrument which includes an inserting part, a manipulating part, and a therapeutic part. In a link mechanism having a transmission shaft for transmitting a driving force applied to the manipulating part to the therapeutic part, the position of the transmission shaft is restricted, and a joint is provided in the transmission shaft to reduce the strain of the transmission shaft. A sheath is also provided in the inserting part to facilitate cleaning thereof. A mechanism is provided for immovably locking the movable portion. A circular arc centered about a turning shaft is introduced into the shape of the manipulating part to improve the manipulability thereof. Further, the structure of a gripping portion of the manipulating part is improved.
