Prosthetics

Abstract

The present disclosure provides a prosthesis. The prosthesis comprises a digit and a drive unit for the digit. The driving unit includes a driving output part, a movable part and a driving rope; the movable part is connected with the driving output part and can move under the driving of the driving output part; the driving rope is arranged in the finger part and is connected with the movable part, and can Convert the movement of the movable part into the motion of the fingers.

Description

technical field [0001] Embodiments of the present disclosure relate to a prosthesis. Background technique [0002] There are a large number of people with disabilities in my country. For example, physical disabilities of upper or lower limbs will cause great troubles to the lives of disabled people, seriously affecting their normal daily life and working ability. Current upper limb prostheses mainly include decorative artificial arms, cable-controlled artificial arms, and myoelectric artificial arms. Although the decorative artificial arm is more beautiful, it has no finger joints, cannot realize grip perception and grip control, and lacks practicability. The finger joints of the cable-controlled artificial arm and the myoelectric artificial arm are mostly a single synchronous movement, which is far from the real human hand movement, and cannot meet the daily needs and psychological satisfaction of users. In addition, due to the different shapes of the residual limbs of ea...

Problems solved by technology

Although the decorative artificial arm is more beautiful, it has no finger joints, cannot realize grip perception and grip control, and lacks practicability

The finger joints of the cable-controlled artificial arm and the myoelectric artificial arm are mostly a single synchronous movement, which is far from the real human hand movement, and cannot meet the daily needs and psychological satisfaction of users.

In addition, due to the different shapes of the residual limbs of each user, the adaptability of the existing arm sleeves is poor, which often causes the problem of wearing discomfort

Even if the online modeling technology is used to customize the prosthetic sleeve, the obtained prosthetic sleeve is expensive, technically difficult, and the manufacturing process is complicated, so it cannot be widely promoted at present.
