Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for raising arms during radiotherapy. Background Art
[0002] At present, the positioning of radiotherapy after breast cancer surgery should be based on the patient's surgical procedure, radiotherapy range and the activity of the affected upper limb. The principle of position fixation is to ensure the repeatability and stability of the patient's position during radiotherapy, while taking into account the patient's comfort. Before positioning for radiotherapy after breast-conserving surgery for breast cancer, it should be confirmed that the patient's affected upper limb can move normally. The breast support is used for positioning, with both hands holding the handrail, with the affected hand below and the healthy hand above, and a B pillow under the head. When the patient holds the handrail with both hands, the lack of support for the arms can easily lead to changes in body position. The different arm positions will affect the changes in the positions of surface landmarks, resulting in positioning errors.

[0027] The swing mechanism 7 includes an arc plate 701, an arc groove 702 is provided on the top of the arc plate 701, a slider 703 is slidably connected inside the arc groove 702, a support rod 704 is fixedly installed at the top center of the slider 703, the top of the support rod 704 is fixedly connected to the wing plate 2, a locking knob 13 is provided through the outer surface of the slider 703, the slider 703 is fixedly connected to the arc groove 702 through the locking knob 13, the slider 703 slides along the arc inside the arc groove 702, the slider 703 is fixedly connected to the top wing plate 2 through the support rod 704, thereby driving the hand support plate 3 to swing and adjust the angle, and the slider 703 is locked and connected to the arc groove 702 through the locking knob 12 to complete the azimuth positioning locking.
[0028] Three positioning holes 8 are provided on the surface of the positioning plate 4, and a spring block 9 is fixedly installed on the surface of the lifting plate 5. The spring block 9 is engaged with any positioning hole 8. The spring block 9 is manually pressed to engage with any positioning hole 8, thereby driving the lifting plate 5 to be pulled out of the interior of the positioning plate 4 to complete the three-speed height adjustment.
[0029] Guide rails 10 are installed on both sides of the top of the support plate 6, and the top of the guide rails 10 is slidably connected to the swing mechanism 7. The guide rails 10 facilitate the movement of the support plate 6 on its top, thereby solving the problem that the prior art lacks orientation adjustment and increasing flexibility.
[0030] Positioning pins 11 are connected through both sides of the surface of the positioning plate 4. The positioning plate 4 is fixedly connected to the fixing holes of the fixing plate 1 through the positioning pins 11. The positioning plate 4 is fixedly connected to the fixing plate 1 through the positioning pins 11, thereby increasing the stability of the overall structure.
[0031] A slide groove is provided at the bottom of the support plate 6, and a plurality of threaded holes are provided at the bottom slide groove of the support plate 6. Positioning bolts 12 are threadedly fastened at the threaded holes of the slide groove of the support plate 6. The positioning bolts 12 pass through the threaded holes to fix the arc plate 701 to the top of the support plate 6, thereby completing the fixed limiting work.
[0032] Lockable telescopic rod structures are provided on both sides of the front end of the support plate 6. The telescopic rods can be used to fix the front end structure of the support plate 6 on the top of the fixed plate 1 to provide stable support. The telescopic design facilitates three-gear height adaptation and adjustment.
[0033] Working principle: when using it, first fix the positioning plate 4 to the fixing holes at both ends of the fixing plate 1 through the positioning pins 11, then the patient lies on the fixing plate 1 and holds the fixing plate handrail with both hands, and places the lower arm on the upper part of the hand support plate 3. The surface of the hand support plate 3 is made of medical cotton material, which increases the patient's comfort and hygiene. According to needs, the spring block 9 can be manually pressed to disengage it from the inside of any positioning hole 8, and then the lifting plate 5 can be manually pulled out from the top of the positioning plate 4, and the spring block 9 is clamped and fixed to any height positioning hole 8 to complete the three-speed height adjustment. When adjusting, the telescopic rods on both sides of the front end of the bottom of the support plate 6 are adjusted to ensure that the support plate 6 is in a relatively horizontal state. After being in the state, it is locked by the bolt structure. According to the needs of different patients, the slider 703 at the bottom of the arc plate 701 can slide inside the arc groove 702, so that the arc plate 701 drives the wing plate 2 structure to move, and then drives the hand support plate 3 to adjust to the required angle to increase the patient's comfort. After the angle is fixed, the slider 703 can be fixed to the arc groove 702 by the locking knob 13 to complete the structural limit. Then, the hand support plate 3 can be manually driven to move on the guide rail 10 to achieve lateral adjustment of the orientation to further adapt to the arm placement requirements of different patients. When it is moved to the appropriate position, the positioning bolt 12 is screwed to the threaded hole to complete the locking of the arc plate 701.
