Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an inspection and positioning device. Background Art

[0002] Radiotherapy is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, and γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams, and other particle beams produced by various x-ray therapy machines or accelerators. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors. Therefore, it is also necessary to optimize the auxiliary equipment in the radiotherapy process.

[0003] For example, a radiotherapy positioning device is disclosed in the Chinese utility model patent with the announcement number CN212817663U. Although the above-mentioned prior art can adjust the lying direction of the person being examined, it is more convenient to position the patient and quickly adjust the direction of the patient's position to make the examination more convenient. However, after the examination, the patient still needs to mark the position for radiotherapy, and some marks are directly marked on the patient's skin. Such marks cannot be adjusted and the patient needs to clean them after the treatment, which is troublesome and time-consuming. Therefore, it is necessary to design an inspection positioning device that can locate the radiotherapy position. Utility Model Content

[0004] In order to solve the technical problem that radiotherapy positioning requires marking on the patient's skin, which is inconvenient to adjust and clean, the utility model provides an inspection positioning device.

[0005] The utility model is implemented by the following technical scheme: an inspection and positioning device, including a positioning ring, both sides of the positioning ring are provided with positioning components for assisting the positioning ring to move for radiotherapy positioning, one side of one of the positioning components is provided with a fixing component for fixing the positioning ring after the radiotherapy position is determined, and one side of the two positioning components is provided with a binding component capable of binding the two positioning components to the patient.

[0006] Through the above technical solution, when the patient is positioned for radiotherapy, the positioning component can be bound to the body by cooperating with the binding component, and the sliding positioning ring can mark the position that needs treatment.

[0007] As a further improvement of the above-mentioned scheme, the positioning assembly includes a positioning bar arranged on one side of the positioning ring and having a sliding groove, and a sliding block slidably installed inside the sliding groove. A limiting plate is fixedly installed on one side of the sliding block, and fixed grooves matching the sliding block are opened on both sides of the positioning ring. The positioning ring slides with the sliding block through the fixed grooves.

[0008] Through the above technical solution, the positioning ring can be removed from the two sliding blocks, and the sliding blocks can be moved so that the positioning ring can mark the position requiring radiotherapy.

[0009] As a further improvement of the above scheme, a movable groove connected to the sliding groove is opened on one side of one of the positioning bars, and the fixing component includes a threaded column arranged inside the movable groove and a rotating block fixedly installed at one end of the threaded column, and the thread at one end of the threaded column passes through the adjacent sliding block.

[0010] Through the above technical solution, after the positioning ring marks the radiotherapy position, the sliding block can be fixed by rotating the threaded column in coordination with the rotating block.

[0011] As a further improvement of the above scheme, the restraint assembly includes a first elastic band installed at one end of the two positioning strips and a second elastic band installed at the other end of the two positioning strips, and the opposing surfaces of the first elastic band and the second elastic band are installed with matching Velcro.

[0012] Through the above technical solution, the two elastic bands combined with Velcro can adapt to patients of different body shapes.

[0013] As a further improvement of the above solution, a sponge strip is fixedly mounted on one side of the two positioning strips.

[0014] Through the above technical solution, when the positioning strip is bound to the patient, the sponge strip can avoid friction damage of the positioning strip.

[0015] As a further improvement of the above solution, the diameter of the rotating block is greater than the distance between the openings of the moving grooves.

[0016] Through the above technical solution, the sliding block can be fixed by the threaded column by rotating the rotating block.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a positioning component, a fixing component and a restraining component. When the patient is positioned for radiotherapy, the restraining component can be used to bind the positioning component to the patient, and the sliding block in the positioning component can be slid according to the required position to move the positioning ring to the positioning position. Finally, the fixing component is used to fix the sliding block. This arrangement can not only adjust the positioning position, but also avoid the need to mark the patient's skin.

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 An inspection and positioning device of this embodiment includes a positioning ring 1, and both sides of the positioning ring 1 are provided with positioning components for assisting the positioning ring 1 to move for radiotherapy positioning. One side of one of the positioning components is provided with a fixing component for fixing the positioning ring 1 after the radiotherapy position is determined, and one side of the two positioning components is provided with a binding component capable of binding the two positioning components to the patient.

[0026] Combination Figure 1-Figure 3 The positioning assembly includes a positioning strip 201 which is arranged on one side of the positioning ring 1 and has a sliding groove, and a sliding block 202 which is slidably installed in the sliding groove. The positioning strip 201 has a certain elasticity and can be bent and fit the patient's epidermis under the pulling of the first elastic band 401 and the second elastic band 402. A limiting plate 5 is fixedly installed on one side of the sliding block 202. Fixed grooves matching the sliding block 202 are provided on both sides of the positioning ring 1. The positioning ring 1 slides with the sliding block 202 through the fixed grooves. The positioning ring 1 can be removed from the two sliding blocks 202. Moving the sliding block 202 can allow the positioning ring 1 to mark the position where radiotherapy is required.

[0027] Combination Figure 1 and Figure 3 A movable groove connected to the sliding groove is provided on one side of one positioning bar 201, and the fixing component includes a threaded column 301 arranged inside the movable groove and a rotating block 302 fixedly installed at one end of the threaded column 301. One end of the threaded column 301 is threadedly penetrated through the adjacent sliding block 202. After the positioning ring 1 marks the radiotherapy position, the sliding block 202 can be fixed by rotating the threaded column 301 in cooperation with the rotating block 302.

[0028] Combination Figure 1The restraint component includes a first elastic band 401 installed at one end of the two positioning strips 201 and a second elastic band 402 installed at the other end of the two positioning strips 201. The opposite surfaces of the first elastic band 401 and the second elastic band 402 are installed with Velcro 6 that cooperate with each other. The two elastic bands and Velcro 6 can adapt to patients of different body shapes.

[0029] Combination Figure 1 A sponge bar 7 is fixedly installed on one side of the two positioning bars 201, and the diameter of the rotating block 302 is larger than the distance between the openings of the moving grooves. When the positioning bars 201 are bound to the patient, the sponge bar 7 can avoid friction damage to the positioning bars 201.

[0030] The implementation principle of an inspection and positioning device in an embodiment of the present application is as follows: when a patient is positioned for radiotherapy, the Velcro 6 of the first elastic band 401 and the second elastic band 402 is opened, and the two positioning strips 201 are bound to the patient's body in conjunction with the first elastic band 401 and the second elastic band 402. When a position needs to be marked, the rotating block 302 is rotated to release the fixing effect of the threaded column 301 and the sliding block 202, so that the sliding block 202 can drive the positioning ring 1 to move, thereby marking the marked position. After marking, the rotating block 302 is rotated to allow the threaded column 301 to cooperate with the sliding block 202 again for fixation, thereby fixing the position of the positioning ring 1 and preventing the positioning ring 1 from moving. This arrangement can make radiotherapy positioning quick and does not require marking on the patient's skin.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
