Cooling and flushing device for animal operation

Abstract

The utility model provides a cooling and flushing device for animal surgery. The cooling and flushing device comprises a support body, an electric cylinder and an injector. An operator steps on a pedal type switch connected with the electric cylinder to control the electric cylinder to work, the electric cylinder drives a piston rod of the injector to move, and therefore water contained in the injector is sprayed out. The flexible tube is mounted on the nipple of the injector, so that the water flow injection direction can be adjusted in advance to be aligned with a to-be-injected part; thus, in the whole operation process, an operator can spray water for cooling or flushing autonomously, and assistants are not needed.
