Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a stent for radiotherapy of colorectal cancer with adjustable function. Background Technology

[0002] When performing radiotherapy on patients with colorectal cancer, especially those with tumors located near the anus, it is usually necessary to keep their legs open and maintain a certain angle. During radiotherapy, the angle of the patient's thighs needs to be maintained stably for a long time. Therefore, the design of stents for colorectal cancer radiotherapy is particularly important.

[0003] Chinese patent CN213491556U discloses a stent for radiotherapy of colorectal cancer, comprising a stent body and a rib plate. The stent body includes a left leg contact plate and a right leg contact plate, with the upper ends of the left leg contact plate and the upper ends of the right leg contact plate connected to form an angle. The two ends of the rib plate are connected to the left leg contact plate and the right leg contact plate, respectively. The rib plate has fixing holes for fixing the stent body to the bed, which can keep the angle of the patient's legs open unchanged, thereby keeping the legs outside the radiotherapy field of view. At the same time, it helps doctors to achieve precise positioning in radiotherapy of colorectal tumors, ensuring the patient's personalized and precise radiotherapy requirements, and improving the efficiency and safety of radiotherapy.

[0004] The above-mentioned approach can support the inner side of the patient's legs, helping to keep the patient's legs outside the radiation field of view. However, the patient's legs are usually in direct contact with the surface of the support frame, which may cause cross-infection between patients and thus affect the effect of radiotherapy for colorectal cancer. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a stent for radiotherapy of colorectal cancer with adjustable function.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A stent for radiotherapy of colorectal cancer with adjustable function includes a fixed cylinder, and adjustable support space components are symmetrically arranged on both sides of the two fixed cylinders. An adjustable angle component is arranged on one side of the adjustable component, and a support plate is fixedly installed on one side of the adjustable angle component. An anti-infection component is arranged on the outer end of the support plate. The beneficial effects of this utility model are: 1. This utility model, by setting an anti-infection component, allows the installation and removal of the fixing sleeve through the hook and loop sides of the Velcro. The fixing sleeve facilitates the replacement of the protective pad, and the protective pad can be replaced regularly, which can avoid direct contact with the patient and prevent cross-infection of bacteria. It can better assist in the radiotherapy of colorectal cancer and make the use of the stent for radiotherapy of colorectal cancer more hygienic. 2. This utility model is equipped with an adjustable support component and an adjustable angle component. The adjustable support component can adjust the distance between the two support plates, thereby adjusting the range of leg opening for the patient. The adjustable angle component can adjust the support angle of the support plates, which can be adjusted according to the needs of the patient and medical staff, making radiotherapy for colorectal cancer more convenient.

[0007] Furthermore, the anti-infection component includes slots formed on the surface of a support plate. Each slot has a Velcro hook fixedly installed inside. The support plate is fitted with a fixing sleeve, the inner wall of which is fitted with a Velcro loop, and a protective pad is fixedly installed on one side of the fixing sleeve.

[0008] The beneficial effect of the above-mentioned further measures is that the replaceable protective pad prevents patients from directly contacting the stent and causing cross-infection.

[0009] Furthermore, the adjustable support space assembly includes a threaded tube, which is fixedly installed on one side of the fixed cylinder. A T-shaped telescopic tube is fixedly installed on one side of the threaded tube. A measuring rod passes through the interior of the T-shaped telescopic tube. A threaded cylinder is fitted onto the outer end of the measuring rod. A T-shaped cylinder is fixedly installed on one side of the threaded cylinder.

[0010] The beneficial effect of the above-mentioned further solution is that the spacing between the adjustable support plates can be adjusted according to the size of the patient's opening, making the support more stable.

[0011] Furthermore, the angle adjustment assembly includes a connecting block, which is fixedly installed on one side of the scale rod. A C-shaped plate is rotatably connected to the outer end of the connecting block, and a bolt passes through the inner wall of the C-shaped plate.

[0012] The beneficial effect of the above-mentioned further solution is that the connecting block and the C-shaped plate can adjust the angle of the support plate 4.

[0013] Furthermore, the bolt penetrates the interior of the connecting block, and a fixing nut is threaded onto the outer end of the bolt. A fixing plate is fixedly installed on one side of the C-shaped plate.

[0014] The beneficial effect of the above-mentioned further solution is that the angle of the support plate can be fixed.

[0015] Furthermore, the two fixed cylinders are of different lengths.

[0016] Furthermore, the hook side and the loop side of the hook and loop are attached together, and the slot is movably connected to the fixing sleeve.

[0017] The beneficial effect of the above-mentioned further solutions is that they facilitate the regular replacement of the protective pads.

[0018] Furthermore, the measuring rod extends into the interior of the fixed cylinder, the threaded tube and the threaded cylinder are threadedly connected, and the T-shaped telescopic tube and the T-shaped cylinder are movably connected.

[0019] The beneficial effect of the above-mentioned further scheme is that it makes it more convenient to adjust the opening angle of the stent used in radiotherapy for colorectal cancer. Attached Figure Description
