Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical facilities, and in particular to a medical tumor radiotherapy positioning verification device. Background Art
[0002] The medical tumor radiotherapy positioning verification device is a device used to ensure that the patient is correctly positioned during radiotherapy treatment. It usually includes a fixed bed and positioning auxiliary equipment, such as lasers, X-rays or photography, etc. These devices help doctors accurately position the patient to ensure that the radiation is accurately irradiated to the tumor and minimize damage to surrounding healthy tissues. Medical staff mainly stand in the medical operation area on one side of the medical tumor radiotherapy positioning verification device to operate.
[0003] Fixed beds are similar to conventional beds. In order to further ensure the stability and accuracy of patient fixation, auxiliary fixation tools such as T-shoes are sometimes required. T-shoes can help doctors locate the patient's body parts more accurately to ensure accurate irradiation of radiation, which is particularly important in ensuring treatment effectiveness and reducing patient exposure doses. However, there are also some disadvantages to using T-shoes. Due to the different shapes, sizes, and shapes of people's feet, T-shoes may not be suitable for all patients, which may cause some patients to feel more uncomfortable when wearing them. In addition, it takes a certain amount of time to install and adjust T-shoes, which prolongs the treatment process and affects the patient's medical experience.
[0004] In response to the above problems, the existing patent proposes a tumor radiotherapy positioning device, that is, two leg fixing mechanisms are added to the fixed bed to replace the T-shoes. The leg fixing mechanism allows the patient to lie flat and place the calf. One side of the leg fixing mechanism is fixed, and the other side can slide laterally to clamp or loosen the calf. After clamping, the leg is then looped with an elastic band arranged on one side of the leg fixing mechanism to assist in fixation. However, since only the calf is fixed when lying flat, in order to ensure the accuracy of radiotherapy and avoid changes in the irradiation position of the radiation due to the movement of the patient's legs as a whole during the treatment, the calf is often clamped during clamping and then fixed with an elastic band. During a long period of treatment, it is easy to cause excessive pressure on the patient's calf, and there is still room for improvement. Utility Model Content
[0005] In order to improve the comfort when fixing the patient's legs during radiotherapy, the present application provides a medical tumor radiotherapy positioning verification device.
[0006] The medical tumor radiotherapy positioning verification device provided in this application adopts the following technical solution:
[0007] A medical tumor radiotherapy positioning verification device includes a positioning verification device body, a fixed bed is provided on one side of the positioning verification device body, a support assembly is connected to one side of the fixed bed, the support assembly includes a vertical pole provided on one side of the fixed bed and a support plate rotatably connected to one side of the vertical pole, a rotating ring for sleeved on the vertical pole is provided on one side of the support plate, the upper end of the support plate is detachably connected to a triangular support platform, and the upper side of the triangular support platform is concavely formed with two resting grooves for legs to rest.
[0008] By adopting the above technical solution, the angle setting of the triangular support table allows the patient's thighs and calves to be supported and more stable, thereby improving the accuracy of positioning during radiotherapy; fixing the triangular support table on the support plate avoids the movement of the triangular support table compared to directly placing the triangular support table on the bed surface, thereby further improving the reliability of fixing the patient's leg position.
[0009] Optionally, the support assembly is arranged on a side away from the medical operation area.
[0010] By adopting the above technical solution, the installation position of the support component is limited, leaving an area for medical operations, which is more in line with actual needs.

[0013] Optionally, two opposite sides of the vertical rod are connected with ball heads, and two opposite sides of the outer circumference of the rotating ring are provided with embedding holes for inserting the ball heads.
[0014] By adopting the above technical solution, when the triangular support table is needed, the support plate is kept facing the side of the fixed bed; after radiotherapy is completed, first pinch the ball heads on both sides with both hands so that the ball heads are no longer embedded in the embedding holes, and then rotate the support plate 180 degrees on the horizontal plane. At this time, the ball heads pop out again and embed in the embedding holes, and the position of the support plate is fixed again, which is convenient for replacing the medical sheets of the fixed bed.
[0015] Optionally, at least two pairs of the ball heads are arranged at intervals along the height direction of the vertical pole, and when the lowest ball head is inserted into the embedding hole, the lower plate surface of the support plate fits against the bed surface of the fixed bed.
[0016] By adopting the above technical solution, before the support plate needs to be rotated, the support plate can be lifted and fixed at the ball head at a higher position to prevent the support plate from being stuck by the medical bed sheet during rotation, thereby improving the convenience of rotation.
[0017] Optionally, the support plate includes a short portion and a long portion supporting the triangular support platform, the short portion is connected to the rotating ring, the long portion is rotatably connected to a side of the short portion away from the rotating ring, and the long portion can be folded down.
[0018] By adopting the above technical solution, when the medical tumor radiotherapy positioning verification device is not needed, the support plate can be rotated 180 degrees on the horizontal plane to away from the fixed bed, and then the long part can be folded down to facilitate the passage of medical staff.
[0019] Optionally, a rotating block is protruded from the long portion toward the short portion, and a square groove rotatably connected to the rotating block is opened on the short portion toward the long portion, and the groove wall of the square groove restricts the spontaneous rotation of the rotating block.
[0020] By adopting the above technical solution, the long part is limited by the cooperation of the square groove and the rotating block, and there is no need to add other additional fixing structures to keep the long part and the short part level, which is easy to operate.
[0021] Optionally, a Velcro adhesive tape is connected between the lower end of the triangular support platform and the upper end of the support plate.
[0022] By adopting the above technical solution and using Velcro to fix the triangular support table, the triangular support table can be replaced regularly to ensure hygiene.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The present application provides a triangular support platform to support the patient's thighs and calves, making them more stable, thereby improving the accuracy of positioning during radiotherapy; at the same time, the triangular support platform is fixed on the support plate, which prevents the triangular support platform from moving compared to directly placing the triangular support platform on the bed surface, further improving the reliability of the patient's leg position fixation;
[0025] 2. The triangular support platform of the present application can move horizontally and vertically under the action of the support assembly, and can also rotate around the vertical pole to match the actual support requirements and cleaning requirements;
[0026] 3. The triangular support table and the support plate are detachably connected, which is convenient for regular replacement and cleaning to ensure a clean and tidy operating room. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.
[0032] A coordinate system XYZ is set in this article, wherein the positive direction of the Z axis represents the top, the negative direction of the Z axis represents the bottom, the positive direction of the Y axis represents the front, the negative direction of the Y axis represents the back, the positive direction of the X axis represents the right, and the negative direction of the X axis represents the left.
[0033] The present application embodiment discloses a medical tumor radiotherapy positioning verification device. Figure 1 The medical tumor radiotherapy positioning verification device comprises a positioning verification device body 1, a fixed bed 2 is arranged at the front side of the positioning verification device, the fixed bed 2 is installed on the ground, and the fixed bed 2 can slide toward or away from the positioning verification device body 1. The positioning verification device body 1 has the same main structure and use principle as the existing medical tumor radiotherapy positioning verification device, the sliding connection method of the fixed bed 2 is an existing means, and the matching relationship and matching principle between the fixed bed 2 and the positioning verification device body 1 are also existing means, which will not be repeated here.
[0034] The right side of the fixed bed 2 is left vacant for medical staff to move around and operate. A transverse track 21 is bolted to the left side of the fixed bed 2 along the front-back direction of the fixed bed 2. The transverse track 21 extends from the foot of the fixed bed 2 to the head of the fixed bed 2, and the length of the transverse track 21 is less than the length of the fixed bed 2. A support assembly 3 is slidably connected to the transverse track 21, and a triangular support platform 4 is detachably connected to one side of the support assembly 3. The upper side of the triangular support platform 4 is concavely formed with two resting grooves 41 for the legs to rest on.
[0035] Reference Figure 2 and Figure 3The support assembly 3 includes a vertical pole 31 arranged on the left side of the fixed bed 2, a support plate 32 rotatably connected to one side of the pole 31, and a transverse sliding block 33 welded to the lower end of the pole 31. The transverse sliding block 33 is inserted into the transverse track 21 and is slidably connected to the transverse track 21, so that the support assembly 3 can slide to meet the leg rest needs of patients of different heights.
[0036] A rotating ring 34 is welded on the left side of the support plate 32, and the rotating ring 34 is sleeved on the vertical rod 31, so that the support plate 32 is rotatably connected to the vertical rod 31. In one specific embodiment, the height of the rotating ring 34 is fixed only by the friction between the inner wall of the rotating ring 34 and the outer periphery of the vertical rod 31; in another specific embodiment, the vertical rod 31 is threadedly connected with multiple ball heads 311 spaced up and down along the height direction of the vertical rod 31, and one ball head ball 311 located at the same height is provided on both opposite sides of the vertical rod 31, that is, at least two pairs of ball head balls 311 are provided at different heights of the vertical rod 31, and the outer wall of the rotating ring 34 is penetrated with an embedding hole 341 for a pair of ball head balls 311 to be inserted one by one. Since the latter installation is more reliable, this application takes the second specific embodiment as an example, and takes a total of two pairs of ball head balls 311 as an example.
[0037] The height of the support plate 32 can be changed by inserting the embedding hole 341 on the rotating ring 34 onto the ball head 311 of the corresponding height. When the lowest ball head 311 on the vertical rod 31 is inserted into the embedding hole 341, the lower surface of the support plate 32 fits the bed surface of the fixed bed 2.
[0038] The support plate 32 includes a short portion 321 and a long portion 322 supporting the triangular support platform 4. A Velcro 5 is bonded between the lower end of the triangular support platform 4 and the upper end of the long portion 322, thereby realizing a detachable connection of the triangular support platform 4 and facilitating replacement of the triangular support platform 4.
[0039] The short portion 321 is welded and fixed to the rotating ring 34, and the long portion 322 is rotatably connected to the side of the short portion 321 away from the rotating ring 34, and the long portion 322 can be turned down. In a specific embodiment, the short portion 321 is consistent with the long portion 322 in height, and the short portion 321 and the long portion 322 are rotatably connected by a hinge between the upper side of the support plate 32 and the junction between the short portion 321 and the long portion 322. When the triangular support platform 4 is used, the long portion 322 is supported by the fixed bed 2; in another specific embodiment, a rotating block 323 is integrally formed on the left side of the long portion 322, and a square groove 324 rotatably connected to the rotating block 323 is provided on the right side of the short portion 321. The long portion 322 can be turned down by bending, but the groove wall of the square groove 324 restricts the rotating block 323 from rotating spontaneously.
[0040] The implementation principle of a medical tumor radiotherapy positioning verification device in an embodiment of the present application is: when the triangular support platform 4 is not needed, first lift the support plate 32 so that the ball head ball 311 arranged on the upper layer of the outer periphery of the vertical rod 31 is inserted into the embedding hole 341, and then rotate it one hundred and eighty degrees counterclockwise in the horizontal plane to make the support plate 32 away from the fixed bed 2, and then fold down the long part 322, so as to reduce the restriction on the movement of medical staff.
[0041] When chemotherapy is needed, the patient is first allowed to lie on the fixed bed 2, and then the long part 322 is bent up, and the support plate 32 is rotated 180 degrees clockwise as a whole, and then the support plate 32 is pressed down, so that the patient's thighs and calves are placed on the placement grooves 41 of the triangular support platform 4, thereby preliminarily fixing the patient's position, and then performing subsequent radiotherapy operations.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
