Description

Technical Field

[0001] This utility model relates to the field of tumor radiotherapy technology, and specifically discloses a device for assisting in tumor radiotherapy positioning. Background Technology

[0002] Radiation therapy for tumors uses radiation or particle technology to treat tumors. While radiation can treat benign diseases, it is primarily used to treat malignant tumors. It, along with surgery and drug therapy, constitutes the three major approaches to treating tumors. Each approach has its own indications and limitations. Different types of tumors, and even the same type of tumor at different stages, require different treatments. Approximately 60% to 70% of patients with malignant tumors have received radiation therapy at some stage of their disease course.

[0003] Traditional tumor radiotherapy positioning devices lack multi-dimensional adjustment structures for the head, shoulders, and lower limbs, making it difficult to adapt to patients of different body types and lacking multi-position positioning for patients. Therefore, a device to assist in tumor radiotherapy positioning is needed to solve this problem. Utility Model Content

The third positioning structure includes an electric slide rail 401 embedded in the second extension plate 4, a headrest 402 slidably connected to the outer wall of the electric slide rail 401 via a slide bracket, a fixing plate 403 fixedly connected to the left and right sides of the headrest 402, a third threaded rod 404 penetrating and threadedly connected to the outer wall of the fixing plate 403, and a third positioning plate 405 movably connected to the third threaded rod 404 via a bearing.

[0020] In this embodiment: the patient lies on the reclining board 2 of the bed board 1, and at the same time, the motor 103 is controlled by an external control structure to work, causing the motor 103 to drive the first threaded rod 102 to rotate (the first threaded rod 102 is a positive and negative threaded rod), causing the two first positioning plates 203 to move relative to each other until the two positioning plates 203 come into contact with the patient's body, and then the patient's body can be positioned by the two arc-shaped positioning plates 203. Next, the electric slide rail 401 is controlled by an external control structure to move the slide carriage and headrest 402 up and down until the headrest 402 matches the patient's head. The headrest 402 then supports and positions the patient's head. The third threaded rod 404 is manually rotated, causing it to push the two third positioning plates 405 to move until they abut against the patient's shoulders. The third positioning structure can then position the patient's shoulders and head. The first and second positioning structures work together to adapt the entire device to patients of different body types and perform multi-position positioning, improving the accuracy of treatment.

[0021] As a technical optimization of this utility model, the second positioning structure includes two long slots that pass through the inside of the first extension plate 3, a second threaded rod 301 rotatably connected to the inside of one of the long slots, a second positioning plate 303 threadedly connected to the second threaded rod 301, and a second slide rod 302 that is slidably connected to the second positioning plate 303 and fixedly connected inside the other long slot.

[0022] In this embodiment: rotating the second threaded rod 301 causes the second threaded rod 301 to drive the second positioning plate 303 to move up and down. The second sliding rod 302 enables the second positioning plate 303 to move stably, and the second positioning plate 303 can then come into contact with the patient's foot, thereby positioning the patient's foot.

[0023] As a technical optimization of this utility model, the rear end faces of both third positioning plates 405 abut against the surface of the second extension plate 4.

[0024] In this embodiment, the third positioning plate 405 can move stably by abutting against the second extension plate 4.

[0025] As a technical optimization of this utility model, a first slide rod 104 is fixedly connected inside the upper through groove 101 and slidably connected to the two first positioning plates 203.

[0026] In this embodiment, the two first positioning plates 203 can be moved stably by the first slide bar 104.

[0027] As a technical optimization of this utility model, the headrest 402 has a concave center and convex structures on the left and right sides.

[0028] In this embodiment, the headrest 402 has a concave center and convex sides, which makes it fit the head better.

[0029] As a technical optimization of this utility model, both the left and right sides of the bed board 1 are located inside the groove 202.

[0030] In this embodiment, since both the left and right sides of the bed board 1 are located inside the groove 202, the two movable plates 201 can move smoothly on the bed board 1.

[0031] The working principle and usage process of this utility model: The patient lies on the lying board 2 of the bed board 1, and at the same time, the motor 103 is controlled by the external control structure to work, causing the motor 103 to drive the first threaded rod 102 to rotate, causing the two first positioning plates 203 to move relative to each other until the two positioning plates 203 come into contact with the patient's body, and then the patient's body can be positioned by the two arc-shaped positioning plates 203. Next, the electric slide rail 401 is controlled by an external control structure to move the slide carriage and headrest 402 up and down until the headrest 402 matches the patient's head. The headrest 402 then supports and positions the patient's head. The third threaded rod 404 is manually rotated to push the two third positioning plates 405 to move until the two third positioning plates 405 abut against the patient's shoulders. The third positioning structure can then position the patient's shoulders and head. Rotate the second threaded rod 301 to drive the second positioning plate 303 to move up and down. The second sliding rod 302 can make the second positioning plate 303 move stably, and then the second positioning plate 303 can come into contact with the patient's foot, thereby positioning the patient's foot. Thus, through the cooperation of the first positioning structure, the second positioning structure and the third positioning structure, the entire device can be adapted to patients of different body types and perform multi-position positioning of patients, thereby improving the accuracy of treatment.
