Rehabilitative manipulator for hand burns and scalds

Abstract

The invention discloses a rehabilitative manipulator for hand burns and scalds, which comprises a mechanical finger, a palm rod, a mechanical wrist and a control system. The structure of the rehabilitative manipulator for the hand burns and scalds is adaptive to a human hand; and the manipulator can realize all degrees of freedom that the human hand has through driving, can guide knuckles and wrist joints to perform corresponding movement in the hand burns and scalds treating and rehabilitating process, exercises the joints and facilitates rehabilitating the skin elasticity, so that the hand functions of the rehabilitated palm are rehabilitated maximally. During the treatment, the manipulator can form variable distance between fingers, avoids forming a web structure, and solves the problems that fingers are respectively wrapped by thick gauze to avoid conglutination between the fingers in the conventional method, so airtightness of a wound surface is caused, the rehabilitation time is prolonged and the rehabilitation of the functions between the fingers is not facilitated. The rehabilitative manipulator for the hand burns and scalds has great significance for early rehabilitating hand functions, relieving the pain of burns and scalds patients, reducing treatment cost and the like.

Description

Technical field [0001] The invention relates to a medical device, in particular to a hand burn and scald rehabilitation manipulator. Background technique [0002] Burns and scalds are damage to skin and other tissues caused by hot water, steam, flame, strong acid, strong alkali, electric current, radiation and other reasons. However, daily household hot water or flame burns are more common. Burns and scalds can cause greater pain to the patient and a longer recovery period. Especially for children who have just learned to walk, they have a wide range of activities, poor self-protection ability, and strong curiosity, and are prone to severe burns. Children's burns and scalds mostly occur on the hands. For burns that are more than two degrees deep, the skin damage is deeper and the treatment is time-consuming. Sometimes skin grafts are required, which may leave serious scars or contracture deformities in certain parts of the body. , Causing dysfunction and even disability. In p...

Problems solved by technology

[0003] In the prior art, there is no suitable rehabilitation method for the treatment of hand burns. After the wound is healed, the finger joints and wrist joints are deformed due to scar formation (especially webbed scar formation between fingers) and skin loss of elasticity. Finger movement is obviously limited, hand function is impaired or even lost, and hand function cannot be recovered even after long-term exercise

In order to avoid the above problems, the traditional method is to use thick dressings for the treatment of hand burns and scalds. Wrap the fingers one by one, but the disadvantages are: it cannot effectively prevent the webbed structure; secondly, dressing the wound too thickly is not conducive to the healing of burns and scalds, and even causes complications such as ulceration, prolonging the recovery time
