Description

Technical Field

[0001] The utility model relates to the technical field of residual limb assistive devices, in particular to an underarm crutch suitable for hand amputation. Background Art

[0002] In the field of medical device technology for assistive rehabilitation, hand amputees face numerous difficulties in mobility. Traditional underarm crutches fail to meet their specific needs and lack stable support. Without the support of their hands, hand amputees require extremely stable crutches, but traditional crutches are prone to shaking and sliding, increasing the risk of falls. Traditional crutches lack appropriate design for prosthetic placement, making it difficult for patients to properly position their prostheses.

[0003] The existing patent publication number is CN209490226U, which discloses a crutch specially designed for amputees, including a main cane, which is rod-shaped and is provided with a buttocks load-bearing bar for padding under the user's buttocks and / or a residual limb load-bearing plate for padding the lower end of the user's residual limb; the upper end of the main cane is provided with a balancing support rod. The main force points are set on the user's buttocks and / or residual limbs, the palms are responsible for supporting and controlling the direction, and the armpits are clamped to maintain stability. Dispersing the force points reduces the local force on the patient's limbs and makes it less likely to get tired. In addition, it also reduces the reaction force of the crutch on the human body. The buttocks and residual limbs are closer to the center of gravity of the human body. Using them as the main force points is more in line with the laws of physics and also in line with people's movement habits, which greatly improves the comfort and convenience of use.

[0004] This amputee crutch has obvious limitations for people with hand amputations. Its design sets the main force points on the hip support bar or the residual limb support plate. However, after hand amputees lose the auxiliary function of their hands, it is difficult for them to effectively use these parts for force support. They usually rely more on the strength of their armpits and upper limbs to operate crutches, but the design of this crutch does not fully consider the needs of this special group, resulting in them being unable to find suitable force points and difficult to achieve stable walking assistance. At the same time, the adjustable parts on the crutch are difficult for hand amputees to operate. Since they cannot use their hands flexibly to adjust, they may need help from others to complete the adjustment, which brings great inconvenience to actual use. To this end, we propose an underarm crutch suitable for hand amputees to solve the above-mentioned problems. Utility Model Content
