Self-powered prosthesis based on rapid prototyping and its manufacturing method

Abstract

The invention discloses a rapid forming based self-power driven artificial limb and a manufacturing method thereof. The artificial limb comprises a palm, a forearm, an upper arm and fingers which are mutually connected, as well as driving ropes and elastic resetting ropes which are arranged among the palm, the forearm and the upper arm and fingers; when the palm or the forearm is buckled, the driving ropes are driven to move, and the fingers are buckled to generate a gripping action; when the palm or the forearm are unbent, the driving ropes are loosened, the fingers are unbent by the elastic resetting ropes, and accordingly, the gripping function of the fingers is completed only through buckling and unbending activity of the palm and the forearm. According to the rapid forming based self-power driven artificial limb and the manufacturing method, components can be rapidly formed through 3D printing, the artificial limb is simple and convenient to manufacture, the period is short, used materials and other components such as the elastic ropes and the like are easy to obtain, therefore, the price is low, and the application range is wide. Besides, the artificial limb is simple to assemble and train and is conveniently worn and used by a user, the complicated training and adaption process can be effectively avoided, and the artificial limb is easy to use and is basic artificial limb with good market significance.

Description

technical field [0001] The present invention relates to the technical field of prosthetics driven by self-power, and more particularly, to a self-powered prosthesis based on rapid prototyping, which is more cost-effective and operable, and a method for manufacturing the prosthesis. Background technique [0002] Prosthetic limbs, also known as "prosthetic limbs", are artificial limbs used by amputees to compensate for partial functions of the missing limbs. Commonly used are upper limb prostheses and lower limb prostheses. In the past, prosthetics were mostly made of aluminum, wood, leather, plastic and other materials, and the joints were made of metal parts, but now the mainstream of prosthetics is titanium alloy and carbon fiber materials. [0003] Currently, prostheses developed by various companies or institutions on the market can be divided into aesthetic functional prostheses and operational functional prostheses according to their functions, and operational functiona...

AI Technical Summary

Problems solved by technology

However, the manufacturing process of functional prostheses is complicated, and there are many supporting equipment, and some of them require complex computer program design, so the price is high, the assembly is complicated, the training period is long, and the user's mastering is also difficult.

These problems undoubtedly limit the application of prosthetics in the majority of ordinary patients.

[0004] To sum up, there is a lack of cost-effective prosthetics in the market. For example, the hand is the prosthesis that requires the most flexibility, and its most basic and important function is the grasping function. The grasping function, the training period is short, and the hand prosthesis that is easy for the patient to grasp has not yet appeared.
