| titleOfInvention | Liquid nitrogen sprayer with endoscope |
| abstract | The invention relates to a liquid nitrogen sprayer with an endoscope, belonging to the field of liquid nitrogen cryotherapy equipment. The spray rod comprises a spray rod body, a storage container, an endoscope and a negative pressure tube, wherein liquid nitrogen is contained in the storage container; one end of the spray rod body is communicated with the storage container, and the camera of the endoscope is arranged at the other end of the spray rod body; one end of the negative pressure pipe is arranged at one end of the spray rod body entering the patient. The spray rod is provided with the endoscope, medical staff can freeze the focus under the visual condition, and the treatment accuracy is high; the negative pressure pipe absorbs the liquid nitrogen evaporation heat absorption water mist, thereby ensuring the visual field of medical personnel and being beneficial to the observation of the medical personnel. The driving turbine drives the driven turbine to rotate to generate negative pressure, external negative pressure equipment is not needed, energy is saved, and the movement and operation are flexible and simple; the storage container is arranged in the handle, so that the one-hand operation is facilitated; the liquid nitrogen spraying response is quick and continuous, repeated pressing is not needed, and the labor intensity of medical personnel is reduced. |
