Problems solved by technology

However, it takes a certain amount of time to ablate tumor tissue, and the continuous ablation of the laser causes the cell tissue to vaporize and generate high-temperature mist. If the heat cannot be dissipated quickly, the temperature can be as high as several hundred degrees, and it is easy to affect the uniformity of heat due to the carbonization of tissue caused by excessive temperature distribution, and cause normal cell damage or even necrosis

Abstract

The invention discloses a heat dissipation device used for laser treatment, which comprises a protection cannula, and is characterized in that a plurality of heat absorption holes are formed in the wall of the protection cannula, wherein a metallic syringe needle is arranged at the front end of the protection cannula; a negative pressure extracting component is arranged at the rear end of the protection cannula; a negative pressure connecting port is formed in the negative pressure extracting component provided with an optical fiber punch hole; an optical fiber channel is arranged in the center of the metallic syringe needle; heat adsorption holes are further formed in the rear part of the metallic syringe needle; and a the optical hole of the negative pressure extracting component is provided with a sealing structure. The heat dissipation device used for the laser treatment has the advantages of simple structure and convenience in use, can absorb high-temperature aerial fog up to the hilt, and prevent normal cell damage even necrosis caused by overhigh temperature.

Description

technical field [0001] The invention relates to medical equipment, in particular to a cooling device for laser therapy. Background technique [0002] In the early stage, laser therapy was mainly used for liver cancer resection during operation, and later developed into B-ultrasound-guided percutaneous puncture to insert optical fiber needles into the tumor interstitium. , causing tumor tissue degeneration and necrosis. However, it takes a certain amount of time to ablate tumor tissue, and the continuous ablation of the laser causes the cell tissue to vaporize and generate high-temperature mist. If the heat cannot be dissipated quickly, the temperature can be as high as several hundred degrees, and it is easy to affect the uniformity of heat due to the carbonization of tissue caused by excessive temperature distribution, and cause damage or even necrosis of normal cells. Contents of the invention [0003] The object of the present invention is to provide a heat dissipatio...
