[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0022] Reference Figure 1-5As shown, an upper arm anti-rotation prosthesis comprises an upper limb receiving cavity 1, a cosmetic artificial hand 2 detachably connected to the upper limb receiving cavity 1, and also comprises a lateral pressure pad 3 and a fastener 5; at least one lateral pressure pad accommodating cavity 4 is provided at the lateral humeral part of the upper limb receiving cavity 1; the lateral pressure pad 3 is correspondingly inserted into the lateral pressure pad accommodating cavity 4; the fastener 5 is attached to the surface of the upper limb receiving cavity 1; the lateral pressure pad 3 is fastened to the upper limb receiving cavity 1 through the fastener 5. The upper limb receiving cavity 1 and the cosmetic artificial hand 2 together constitute the main body of the upper arm anti-rotation prosthesis; the lateral pressure pad 3 is inserted into the lateral pressure pad accommodating cavity 4 and can be easily taken out. During the process of the patient wearing the prosthesis, since the lateral pressure pad 3 is located in the lateral pressure pad accommodating cavity 4, it is not easy to fall out, and it is fixed by the fastener 5, which can effectively fix the upper arm prosthesis so that it does not rotate under the action of the lateral pressure pad 3, and effectively ensures the wearing stability of the upper arm prosthesis.
[0023] Specifically, the number of the side pressure pad accommodating cavities 4 is three. In the present invention, three side pressure pad accommodating cavities 4 are provided, which can effectively fix the upper arm prosthesis and tighten the upper limb receiving cavity 1 to ensure that it can be stably installed.
[0024] Specifically, the three side pressure pad accommodating cavities 4 are located on the front, inner and rear sides of the humerus part on the side of the upper limb receiving cavity 1. After actual use, it is found that when the three side pressure pad accommodating cavities 4 are respectively arranged on the front, inner and rear sides of the humerus part on the side of the upper limb receiving cavity 1, the upper arm can be fixed to prevent rotation.
[0025] Specifically, in order to ensure the suspension effect of the prosthesis, the fastener 5 is made of nylon elastic Velcro.
[0026] Specifically, the fastener 5 includes a nylon rope 51 and a rope buckle 52; the two ends of the nylon rope 51 are detachably connected to the upper buckle body and the lower buckle body of the rope buckle 52 respectively. After the final test, the utility model found that the use of the nylon rope 51 and the rope buckle 52 can facilitate the daily use of the patient, and the patient can complete the tightness adjustment of the upper arm anti-rotation prosthesis by himself, which is more convenient to wear the upper arm anti-rotation prosthesis. The rope buckle 52 of the utility model can be adapted by the patent publication number CN216983769U "A Clothing Rope Buckle with Elasticity Adjustment". Of course, those skilled in the art can also make reasonable choices according to actual conditions, which will not be repeated here.
[0027] Specifically, in order to further prevent the prosthesis from rotating, the upper limb receiving cavity 1 includes a receiving cavity body 11 and a lap joint 12 ; the receiving cavity body 11 and the lap joint 12 are integrally formed; and the lap joint 12 is located at the upper end of the receiving cavity body 11 .
[0028] Specifically, the upper limb receiving cavity 1 is made of acrylic resin material. Acrylic resin material has excellent fullness, gloss, hardness, solvent resistance, weather resistance, and does not change color or turn yellow when baked at high temperature. It is very suitable for making the upper limb receiving cavity 1.
[0029] Specifically, the side pressure pad 3 is made of EVA, and the EVA material has the characteristics of high toughness and impact resistance.
[0030] The working principle of this utility model:
[0031] When wearing the utility model, first, the upper limb receiving cavity 1 and the cosmetic artificial hand 2 are installed in the prescribed manner; then, the receiving cavity body 11 of the upper limb receiving cavity 1 is held to place the patient's residual limb into the upper limb receiving cavity 1, and the overlapping part 12 is located at the patient's shoulder position to improve the anti-rotation function of the prosthesis; thereafter, the side pressure pad 3 is inserted into the side pressure pad accommodating cavity 4, and then the fastener 5 is attached to the part with the side pressure pad 3, and the side pressure pad 3 and the upper limb receiving cavity 1 are completely tightened by using nylon elastic Velcro or nylon rope 51 and rope buckle 52, so that it has a certain degree of squeezing on the upper limb receiving cavity 1, effectively ensuring the suspension effect of the prosthesis, preventing the prosthesis from rotating due to force majeure when used in daily life, and making it more convenient for patients to wear it in life.
[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
