A medical instrument includes a handle with a fixed part, a movable part, a locking device, a shaft releasably locked on the handle by the locking device, and a jaw arranged on the shaft. The jaw is movable between open and closed positions by actuation of the movable part. A push-pull element is guided in the shaft and operatively connected to the movable part and to the jaw. The locking device has an actuation element that is movable into a release position to release the locking, and a blocking element which is connected to the movable part and movable into a blocking position in a working position of the movable part, in which the blocking element blocks mobility of the actuation element, and which is movable into an enabling position in a rest position of the movable part, to permit mobility of the actuation element.

The invention provides a wearable manual control simulation cattle. The wearable manual control simulation cattle comprises a cattle body assembly, a cattle head assembly and a cattle eye assembly. The cattle body assembly is fixed to the back of an operator through a bandage, bracket frameworks on the two sides of the cattle body assembly are connected with the two legs of the operator in a staggered mode through bracket pull wires, and brackets are driven to simulate actions when the cattle body assembly walks. The head assembly is hung on the neck framework through a ball head and a ball groove structure and can deflect flexibly. An operator manipulates the eye handle and the operation handle on the head skeleton with one hand, and controls the two eyes to blink synchronously through the stay wire; and the other hand operates a mouth operation handle on the neck skeleton, and the mouth is controlled to be opened and closed through a pull wire to simulate chewing. The device is flexible in structure, capable of vividly simulating walking, blinking and chewing actions of the cattle, convenient to operate and high in performance ornamental value.
