Description

Technical Field

[0001] This utility model relates to the field of intrinsic fluorescence diagnostic instruments, specifically an intrinsic fluorescence early tumor diagnostic instrument. Background Technology

[0002] Tumors are new growths formed by the proliferation of local tissue cells under the influence of various carcinogenic factors. Studies have found that tumor cells exhibit metabolic changes that differ from normal cells. At the same time, tumor cells can adapt to changes in the metabolic environment by switching between glycolysis and oxidative phosphorylation.

[0003] The fluorescence spectroscopy precancerous lesion diagnostic instrument, also known as the "photobiopsy" diagnostic instrument, can detect lesions 2-3 mm below the mucosa that are difficult to observe with the naked eye. It can block the formation and development of cancer through early treatment. It has high sensitivity and specificity for detecting superficial mucosal tissue lesions (early cancer, especially dysplasia). It is simple, fast, effective, non-invasive, localized, and provides intuitive results.

[0004] Existing intrinsic fluorescence diagnostic instruments mainly use high-pressure mercury lamps as light sources. High-pressure mercury lamps generate a lot of heat when they are working. Currently, products on the market generally use a temperature alarm module in the light source module to trigger an alarm when the temperature is high, requiring the user to stop the machine to cool it down. This method can protect the light source from overheating, but it does not fundamentally solve the problem, and the diagnostic instrument cannot work continuously for a long time.

[0005] To address the aforementioned problems, the inventors proposed an intrinsic fluorescence early tumor diagnostic instrument to solve these issues. Utility Model Content

[0008] Preferably, the heat dissipation unit further includes a temperature sensor, which is mounted on the high-pressure mercury lamp.

[0009] Preferably, the water tank is installed outside the shell, and a cooling fan is installed on the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] By setting up a heat dissipation unit and starting the pump, the cooling water in the water tank is pumped into the heat pipe to remove the heat from the high-pressure mercury lamp, thus preventing the high-pressure mercury lamp from overheating. The excitation light generated by the high-pressure mercury lamp is reflected by the reflector to the focusing unit. After being focused by the focusing unit, the light enters the filter unit. Finally, the fluorescence excitation light is transmitted to the lesion site by an external optical fiber probe, achieving a diagnostic effect. It can achieve long-term non-stop operation.

The heat-conducting pipe 253 is wound around the upper and lower parts of the high-pressure mercury lamp 221.

[0020] During operation, when electrode 222 is energized, high-pressure mercury lamp 221 emits light and generates heat.

When in use, the light source unit 200 can be pulled out of the mounting groove for heat dissipation.
