[0002] Spectral therapy devices utilize a spectrum in the 0.4-3.6μm band to irradiate the surface of the human body or cavity. This combined photothermal effect effectively kills diseased cells and tissue, coagulates mucous membranes, and blocks blood vessels, achieving a cure. The lens assembly of the spectral thermal therapy device is designed to release a specific laser beam to irradiate the surface of the human body or cavity. This combined photothermal effect effectively kills diseased cells and tissue, coagulates mucous membranes, and blocks blood vessels, achieving a cure.

[0019] The heat sink 10 is made of metal.

The heat sink 10 includes an upper heat sink 11, a lower heat sink 12, and a plurality of heat sink slots 13 arranged on the outer edges of the upper heat sink 11 and the lower heat sink 12.

[0020] The upper heat sink 11 and the lower heat sink 12 are connected by fasteners to form a complete heat dissipation structure. The upper heat sink 11 is shaped like an oblate cylinder. The outer edge of the upper heat sink 11, facing the laser output, is chamfered to ensure safer installation and prevent injuries to users caused by the sharp edges of the heat sink 10.

[0021] The lower heat dissipation shell 12 is in the shape of an oblate cylinder. The outer diameter and inner diameter of the lower heat dissipation shell 12 are corresponding to those of the upper heat dissipation shell 11 , so that the upper heat dissipation shell 11 and the lower heat dissipation shell 12 can be mounted together.

The heat dissipation slots 13 avoid the connection structure 40 and are located outside the connection structure 40. The heat dissipation slots 13 increase the heat exchange area between the heat dissipation shell 10 and the outside world, thereby improving heat dissipation efficiency.

A liquid material with a high specific heat capacity, which requires a large amount of heat to increase in temperature, is used as a coolant in the heat-absorbing cooling structure 20 to promote heat dissipation from the heat dissipation housing 10.

The inner diameter of the first retaining edge 233 is smaller than the diameter of the upper through hole 23, and its outer diameter is larger than the inner diameter of the upper cooling groove 21. The first retaining edge 233 supports the first glass slide 25 to prevent it from falling through the upper through hole 23. A second sealing ring 234 is provided between the first sealing groove 232 and the first retaining edge 233. The second sealing ring 234 cooperates with the first glass slide 25 to seal the heat-absorbing cooling structure 20.

[0033] The second locking groove 42 is provided corresponding to the first locking groove 41. The second locking groove 42 cooperates with the first locking groove 41 to form a complete locking groove for setting a fastener. Depending on the fastener used, the shape of the second locking groove 42 is different.
