Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0032] Such as figure 1 As shown, this embodiment includes: a receiving mechanism, an elbow joint 5, a wrist joint 7, a manipulator 8, a housing 6 and a control system.

[0033] The receiving mechanism is composed of a first receiving component 1 and a second receiving component 3, which are made of resin material. The first receiving component 1 and the second receiving component 3 are connected by a flexible material. The bandage 9 is used to fix the first receiving component 11 on the human body, w...

Abstract

The invention provides an artificial limb system aiming at upper-limb high amputation patients. The artificial limb system comprises a receiving mechanism, an elbow joint, a wrist joint, a mechanical arm and a control system, wherein the receiving mechanism and the elbow joint are connected through a connecting flange; the elbow joint and the wrist joint are connected through a connecting rod, and a cavity is reserved between the elbow joint and the wrist joint; the elbow joint is used for driving the wrist joint and the mechanical arm to move in the space; the wrist joint is used for adjusting the posture of the mechanical arm in grabbing the object; the mechanical arm comprises 5 fingers, and the fingers can move independently; the control system is used for controlling the receiving mechanism, the elbow joint, the wrist joint and the mechanical arm. Compared with the prior art, the artificial limb system has the beneficial effects that the elbow joint is driven by a brushless motor and adopts a harmonic reducer, the structure is compact, and the noises are small. The wrist joint adopts a conducting ring, and thus a power supply and a communication channel are provided for the power supply of a tactile feedback sensor and a mechanical arm controller.

Description

technical field [0001] The invention relates to the field of rehabilitation of disabled persons, in particular to a prosthesis system for upper limb high amputee. Background technique [0002] According to the second sample survey of disabled persons in China in 2006, there were as many as 24.12 million amputees. Because of the loss of motor ability, the quality of life of these people has been greatly impaired. It also makes this a social issue that has attracted much attention. For this group of people, a prosthesis with excellent performance is needed to restore their motor function. Especially for high amputee upper limbs, due to the heavy load on the elbow joint, the current method used in commercial prostheses is to increase the torsion spring, but this will increase the resistance when doing elbow extension. And the motors used in most commercial prosthetics are brushed motors, which leads to loud noise when the prosthetics are running. And most of the current com...
