The invention relates to the field of
medical equipment, in particular to a low-temperature compact twinge equipment utilizing CO2 rapid cooling. The equipment is characterized in that a
carbon dioxide steel cylinder is arranged inside an instrument shell, an outlet is connected with a gas
injector pipe, an
injector head is installed at the other end of the gas
injector pipe, and the injector headis installed inside a spraying gun; a controller is installed inside the instrument shell, and a touch type
liquid crystal panel connected with the controller is installed on the instrument shell; the injector head is a revolved body shaped valve body, the valve body is sleeved with an
electromagnetic coil which is in circuit connection with a power supply component, an adjusting rod, a
piston and an
evaporation refrigeration cabin are sequentially and coaxially installed inside the valve body, the outer
diameter of the
piston and the outer
diameter of the adjusting rod are smaller than the
diameter of an inner hole of the injector head to form a
carbon dioxide flow channel, one end of a spring is connected with the adjusting rod, the
piston is installed at the other end so that the spring can drive the piston to move to control the flow channel to be opened and closed, and a liquid flow guiding groove is formed in the adjusting rod. The equipment has the advantages that the local lowtemperature
impact position is convenient to control,
percutaneous surface cooling speed is high, the automatic degree of the equipment is high, the service life of an
impact head is long, and the product using cost is low.
