Equipment for automatic quantifying damages of peripheral nerves of experimental animals

The utility model relates to equipment for automatic quantifying damages of peripheral nerves of experimental animals. The equipmen comprises damage forceps, a power device and a control device. A fixed pole and a movable pole are arranged on the damage forceps. A metal hinge and a sensor are installed on the surface of the movable pole. A metal frame is further arranged on the damage forceps and wraps the fixed pole, the movable pole, the sensor, a reset ring, a ladder-type tongue depressor, a flexible component, and a first piston, wherein the movable ladder-type tongue depressor is arranged on the surface of the sensor; one end of the reset ring is connected with the movable pole, and the other end is connected with the ladder-type tongue depressor; one end of the flexible component is connected with the ladder-type tongue depressor, and the other end is fixed in the wall of the metal frame; and the tail end of the first piston is connected with a hydraulic pipe. With an accuracy of no lower than 95%, the device is suitable for neurologic damages in deep and narrow spaces. Controlled by an electronic program, the device eliminates artificial factors and provides controllable and adjustable damage force and duration and high comparability in damage degree.
