Description

Technical Field

[0001] This utility model relates to the field of lesion localization technology, and in particular to a radiotherapy and thermotherapy synergistic device based on precise lesion localization. Background Technology

[0002] Radiotherapy is the treatment of malignant tumors and some benign diseases using one or more types of ionizing radiation. The means of radiotherapy is ionizing radiation, while thermotherapy uses high temperature to destroy the membrane structure of cancer cells, thereby inhibiting the proliferation of cancer cells. Currently, patients are generally treated by combining radiotherapy and thermotherapy.

[0003] In existing radiotherapy and thermotherapy combined devices, external light can easily affect X-rays during pre-treatment testing, reducing the effectiveness of X-rays and thus affecting the accuracy of CT scans. This can lead to the need for patients to undergo re-examination, or even cause medical staff to view unclear images, resulting in diagnostic errors and affecting the patient's optimal treatment time.

Two fixing plates 208 are fixedly connected to the outer wall of the movable rod 209, and elastic elements 211 are provided on the... On one side of the two fixed plates 208, a telescopic spring 210 is movably connected to the outer wall of the movable rod 209. The two ends of the telescopic spring 210 are respectively fixedly connected to the two sides of the fixed plate 208. An electric drive rod 202 is fixedly connected inside the multiple support frames 201. A movable frame 204 is fixedly connected to the drive end of the electric drive rod 202. An mounting plate 203 is fixedly connected to the bottom of the support frame 201. One side of the movable frame 204 is movably connected to the inside of the mounting plate 203. The same limiting member 205 is provided on the opposite sides of the two movable frames 204 located on the same side.

[0023] Reference Figure 1 and Figure 4 In a preferred embodiment, a sliding groove is provided on one side of the moving platform 3, and a hydraulic rod 401 is fixedly connected to one side of the sliding groove. The driving end of the hydraulic rod 401 is fixedly connected to a mounting frame 403, which is movably connected inside the sliding groove. Mounting holes are provided on both sides of the mounting frame 403, and a rotating shaft 404 is movably connected inside the two mounting holes.

[0024] Working principle: Before the device examines the patient, the drive motor 207 is activated. The drive motor 207 causes the movable rod 209 to move the elastic element 211, which rolls up and releases the light-blocking curtain 212. The elasticity of the telescopic spring 210 and the elastic element 211 prevents damage to the surface of the light-blocking curtain 212 during rolling, thus affecting its light-blocking effect. At this time, the electric drive rod 202 is activated. The electric drive rod 202 drives the moving frame 204 to move inside the mounting plate 203, so that the limiting element 205 can limit the light-blocking curtain 212, preventing the light-blocking curtain 212 from shifting. This would cause external light to produce a double image on the patient's body surface, affecting the detection effect, thereby affecting the detection accuracy of the CT scanner, reducing the rate of diagnostic errors, and affecting the patient's optimal treatment time.

[0025] After the examination is completed, the laser emitter 5 emits a laser to irradiate the lesion area of ​​the patient. At the same time, the hydraulic rod 401 is activated, which moves the positioning component to the corresponding position. The servo motor 402 and the telescopic rod 406 are activated. The servo motor 402 and the telescopic rod 406 drive the deflection plate 405 and the positioning plate 407 to adjust and determine their positions, so that the marking pen 408 can accurately mark the lesion in the laser irradiation area without the need for medical staff to mark it manually, reducing their operation steps.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
