Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary support frame for tumor radiotherapy, and specifically relates to an auxiliary support frame for tumor radiotherapy. Background Technology

[0002] Radiation therapy is a local treatment method that uses high-energy radiation to destroy the DNA of tumor cells, inhibiting their growth or eliminating cancer cells. Its core principle is to precisely eliminate cancer cells while protecting normal tissue by utilizing the difference in the killing ability of radiation on tumor cells and normal tissue cells. Radiation therapy supports (positioning frames) are auxiliary devices used in radiation therapy to stabilize the patient's position and ensure that radiation accurately irradiates the tumor area.

[0003] The aforementioned device lacks an adjustable and slightly offset structure for the fixed frame handle during use. This means that existing radiotherapy positioning frames require patients to lie on the support frame, raise their hands overhead to grasp the top handles for radiotherapy. However, since the top handles are fixed and patients must maintain a supine, raised-arm position for extended periods during treatment, they are prone to fatigue or other discomfort. Furthermore, the existing top handles cannot be adjusted in length, making it impossible to adjust the handle length according to the patient's body shape, which also causes discomfort. Based on the shortcomings of existing technology, this utility model designs an auxiliary support frame for tumor radiotherapy. Utility Model Content

The connecting rod 301 is slidably connected to the inside of the sleeve 406. The fixed rod 302 is fixedly connected to one side of the connecting rod 301. The threaded groove 303 is opened on one side of the fixed rod 302. The handle 304 is slidably sleeved on the outer surface of the fixed rod 302. The annular groove 305 is opened inside the handle 304. The knob 306 is rotatably connected to one side of the handle 304. The threaded rod 307 is fixedly connected to one side of the knob 306.

[0021] The knob 306 is rotatably connected inside the annular groove 305, and the threaded rod 307 is threadedly connected inside the threaded groove 303.

[0022] Further explanation is needed: by rotating the knob 306, the threaded rod 307 rotates inside the threaded groove 303. When the threaded rod 307 rotates and moves inside the fixed rod 302, it can drive the handle 304 to move on the outer surface of the fixed rod 302. The connecting rod 301 is located inside the sleeve 406. The position of the connecting rod 301 inside the sleeve 406 can be easily adjusted by the limit knob 409.

[0023] Example 3 Please see Figure 3-6 The present invention provides the following technical solution: The offset mechanism 4 includes a slider 401, a baffle 402, a traction spring 403, an arc-shaped block 404, an arc-shaped block 405, a sleeve 406, a fixing block 407, a connecting hole 408, and a limit knob 409. The slider 401 is slidably connected to the top of the positioning plate 2. The baffle 402 is fixedly connected to the top of the slider 401. The traction spring 403 is movably engaged with the top of the slider 401. The arc-shaped block 404 is fixedly connected to the top of the slider 401.

[0026] The limit knob 409 is rotatably connected inside the sleeve 406, and the limit knob 409 is located inside the limit groove 308.

[0027] Further explanation is needed: When the patient holds the handle 304 and needs to move it slightly, the connecting rod 301 and the sleeve 406 can be pulled inward, at which point the traction spring 403 will rotate and stretch, making it easier for the patient to relax their arm. After relaxation, the traction force of the traction spring 403 will drive the connecting rod 301 and the sleeve 406 to return to the vertical state.

[0028] Working principle: When an auxiliary support frame for tumor radiotherapy is used, an air cushion 101, a leg support 102 and a foot support 103 are first set on the top of the support plate 1 to facilitate patient use. A positioning plate 2 is set on the top of the support plate 1. The positioning plate 2 facilitates the connection of the gripping mechanism 3 and the offset mechanism 4. The adjustment of the gripping mechanism 3 and the offset mechanism 4 can be adapted to different patients. When it is necessary to adapt to different patients, the threaded rod 307 is first rotated inside the threaded groove 303 by rotating the knob 306. When the threaded rod 307 rotates and moves inside the fixed rod 302, it can drive the handle 304 to move on the outer surface of the fixed rod 302. The connecting rod 301 is set inside the sleeve 406. The position of the connecting rod 301 inside the sleeve 406 can be easily adjusted by the limiting knob 409. This device is easy to adapt to different patients.

[0029] When it is necessary to facilitate the patient's arm relaxation or to accommodate different patients' arm lengths, the connecting rod 301 and sleeve 406 can be pulled inward when the patient is holding the handle 304 and needs to move slightly. At this time, the traction spring 403 will stretch, which will facilitate the patient to relax their arm. After relaxation, the traction force of the traction spring 403 will drive the connecting rod 301 and sleeve 406 to return to the vertical state. This device facilitates the patient to relax their arm or to accommodate different patients' arm lengths.

[0030] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
