Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and specifically to a multi-mode image-guided photodynamic precision diagnosis and treatment device. Background Art
[0002] Photodynamic therapy is a treatment method that uses the interaction between light, photosensitizers and oxygen molecules to produce cytotoxic substances to destroy diseased tissues. It has high selectivity because the distribution of photosensitizers in diseased tissues and normal tissues is different, and reactive oxygen species are only produced under the irradiation of light of a specific wavelength, thereby killing diseased cells and causing relatively little damage to surrounding normal tissues. Photodynamic therapy also has the advantages of repeatability and minimal invasiveness. Compared with traditional surgery, it does not require large-scale tissue resection, which is beneficial to the patient's postoperative recovery; compared with chemotherapy, its side effects are relatively mild and have less impact on the physiological functions of the whole body. In addition to cancer, some non-tumor diseases such as cardiovascular diseases (such as accurate detection and treatment of atherosclerotic plaques) and certain neurological diseases (such as accurate intervention of local brain lesions) also require more accurate diagnosis and treatment methods. Traditional diagnosis and treatment methods have room for improvement in accuracy, specificity and safety. At present, when using tube-powered diagnostic and treatment equipment, the lamp tube is prone to generate high heat when working for a long time. The high temperature can easily cause damage to the photodynamic lamp board. Moreover, the high temperature generated by the photodynamic lamp tube can easily cause high temperature intrusion to the treatment area of the therapist, causing discomfort to the therapist.

[0011] Preferably, the cooling component includes a connecting air duct, which is arranged at the top of the fan, a cooling trough pipe is arranged on the inner side of the top of the connecting air duct, and the bottom end of the cooling trough pipe is connected to the outer wall of the lamp panel housing, a small water chiller is arranged on the outer wall of the cooling trough pipe, a cold water pipe is arranged on the top of the small water chiller, and the middle section of the cold water pipe is coiled inside the cooling trough pipe, and the joints at both ends are connected to the small water chiller.
[0012] Compared with the prior art, the present invention has the following beneficial effects: The heat dissipation plate, strip slot plate, fan and heat dissipation components are set up to effectively dissipate the heat generated by the photodynamic lamp source during long-term operation. The multiple through holes on the surface of the heat dissipation plate increase the heat dissipation area. The heat is sucked into the strip slot plate through the suction of the fan, and the hot air is discharged through the connecting hose and other heat dissipation components. This heat dissipation mechanism can prevent the photodynamic lamp source from overheating due to long-term operation, resulting in performance degradation and shortened life, ensuring the stable performance of the photodynamic diagnosis and treatment device during long-term use and reducing the maintenance cost of equipment failures caused by overheating.
[0013] The adjustment plate can adjust the angle of the strip slot plate and can adjust the direction of the heat dissipation channel according to actual heat dissipation needs. This adjustable design increases the flexibility of the heat dissipation structure, allowing it to adapt to different working environments and equipment layouts, further optimize the heat dissipation effect, and improve the reliability and adaptability of the equipment.

During the installation of the equipment, the connection of components can be quickly completed through the cooperation of the fixed block and the fixed component. When the equipment is maintained or repaired, the relevant components can be easily disassembled. The limit block limits the rotation of the fixed block by 90°, which not only ensures the stability of the connection structure, but also facilitates operation and improves the maintainability of the equipment.
[0015] The structural design of the chiller, cold water pipe and cooling trough pipe allows the temperature of the air blown out by the heat sink to be adjusted, so that the patient can reach a comfortable temperature on the surface of the treatment position during treatment, thereby alleviating pain.

A heat sink component for dissipating the heat generated by the photodynamic lamp source 3 working for a long time is arranged on the outer side of the strip groove plate 5. Connecting rotating rods 9 are arranged on both sides of the adjustment plate 4, and a fixed block 10 is arranged on the outer side of the connecting rotating rod 9. Fixed components for limiting the fixed block 10 are arranged on both sides of the outer wall of the lamp board housing 2.

[0021] The fixing component includes a limiting sleeve 11, which is arranged on the outer wall of the lamp panel housing 2. The limiting sleeve 11 is used to support and limit the fixing pin 12. The limiting sleeve 11 is internally movably provided with a fixing pin 12 for fixing the fixing block 10. When the fixing pin 12 moves downward, it is inserted into the interior of the fixing block 10 to fix the fixing block 10. A counterweight block 13 is arranged on the top of the fixing pin 12.

[0024] Working principle: When using a multi-mode image-guided photodynamic precision diagnosis and treatment device, the user first moves the photodynamic diagnosis and treatment device near the patient, and then the user drives the light board housing 2 with the connecting bracket 1 to move the photodynamic light source 3 to the position where the patient needs to be treated. Then the medical staff injects the photosensitizer into the patient's body, and then controls the photodynamic diagnosis and treatment device to start working through the external control unit, and then starts to work through the photodynamic light source 3 to irradiate the position where the patient needs to be treated. The chemical reaction produced by the cooperation of the photodynamic light source 3 and the photosensitizer can irradiate the lesion position in the patient's body. To kill, when the photodynamic lamp source 3 is used for a long time, the surface of the photodynamic lamp source is prone to high temperature. At this time, the staff controls the fan 8 to start working through the external control unit. The heat inside the lamp board housing 2 is sucked in through the heat sink 6, and then transported to the inside of the connecting hose 7 through the strip groove plate 5 and then discharged through the fan 8. When the patient is irradiated and treated by the photodynamic lamp source 3 for a long time, the irradiated position of the patient is prone to discomfort due to the high temperature. At this time, the fixing pin 12 can be pulled upward, and the fixing pin 12 can be limited by the limiting sleeve 11 when pulling. Then, when all the fixing pins 12 are pulled out from the inside of the fixing block 10, the user rotates the fixing block 10, and then drives the heat sink 6 to rotate at the same time through the connecting rod 9. Then, when the heat sink 6 rotates to the bottom end of the lamp panel housing 2, the position of the limit block 14 just moves to the other end of the strip slide groove. Then, the user inserts the fixing pin 12 downward into the position of the fixing block 10 to fix the fixing block 10. Then, the user controls the fan 8 through the external control unit to start reversing to blow air into the inside of the connecting hose 7 and then enter the heat sink 6 through the strip groove plate 5. The exhausted air is discharged from the inside and blown into the patient treatment position, which can effectively alleviate the patient's discomfort caused by high temperature. The user can also start the small chiller 17 to transport cold water to the inside of the cold water pipe 18. The cold water circulates continuously in the cold water pipe 18. The cold air inside the cooling trough pipe 16 is transported to the inside of the connecting hose 7 through the fan 8 and then blown to the patient treatment position through the heat sink 6. The user can control the temperature of the cold water produced by the small chiller 17 through the external control unit, so that the blown cold air reaches a comfortable temperature.
