The present invention relates to a medical device for general surgery. The surgical device includes a medical device which is used to hold long metallic wire pins inserted into broken bones to connect each other. According to an embodiment of the present invention, the medical device used in surgical operations including the wire pin insertion procedure consists of: a trigger unit equipped with one or more lever; a sensor body equipped with a magnet in its end and movable by the trigger unit; a sensor unit that detects the distance between the sensor body and the magnet; a shaft having a number of magnets in a circumference direction and a through hole in a longitudinal direction; a motor unit equipped with a conductive coil separately disposed in the circumference of the shaft; a control unit that is provided with the distance between the magnet of the sensor body and the sensor unit from the sensor unit and then reduces the amount of electric current to the conductive coil if the distance lengthens while increasing the amount of electric current to the conductive coil if the distance shortens; a driving unit driven by the motor; and a power supply unit that feeds power to the control unit. The revolving unit, together with the shaft through hole, forms a pathway for the wire pin to go through. |
