Problems solved by technology

When the object to be grasped is relatively small, the thumb needs a large range of motion, and the elbow joint requires a large bending angle, which will affect the grasping efficiency and use effect, and it does not match the normal human grasping simulation.

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] According to attached Figure 1-3 It can be seen that the present invention specifically relates to a new type of prosthesis, specifically the movement of fingers or front joints of a prosthesis driven or reset by a human body joint through a drive rod, and its structure specifically includes an upper arm fixing surface 1, a forearm fixing sleeve 4 and fingers, The upper arm fixed surface 1 and the forearm fixed sleeve 4 are hinged by screws, and relative rotation can be realized between the two. The fingers include the thumb 16 and the remaining four fingers 13, wherein the four fingers 13 are fixed by the four-finger reinforcement frame 12, and the thumb 16 and the four fingers are fixed. The fingers 13 are all connected with the forearm fixed sleeve 4 through the rotation shaft 11, so that the thumb 16 and the four fingers 1...

Abstract

The invention discloses a novel artificial limb. The novel artificial limb comprises an upper limb fixing surface, a front arm fixing cover and a finger, wherein the upper limb fixing surface is hinged to the front arm fixing cover, the finger comprises a thumb and other four finger bodies, the thumb and the four finger bodies are all connected with the fixing cover through a rotation shaft, the thumb and the four finger bodies are connected with a driving mechanism through respective driving rod, the driving mechanism passes through the front arm fixing cover and is connected with the upper limb fixing surface, through the rotation of the upper limb fixing cover, and the thumb and the four fingers are driven to swing relatively so that grabbing and stretching can be simulated. According to the novel artificial limb, through a leverage effect of a transmission rod, the motion is conducted to a front end joint or the fingers in sequence, thus the movements of the front end joint and the fingers are achieved, and finally the reestablishment of an open-close function of a hand and the joint is achieved; the novel artificial limb is simple in structural assembly, simple in training, and convenient for a user to wear and use; besides, the complicated training and adaptive process is avoided, and the functional recovery of the artificial limb is achieved.

Description

technical field [0001] The invention relates to the field of human medical devices, in particular to a novel artificial limb. Background technique [0002] The prostheses developed by various companies or institutions on the market are divided into aesthetic functional prostheses and operational functional prostheses according to their functions. Aesthetically functional prostheses only have appearance and no function of movement, so the acceptance level of patients is low. Operational function prostheses can be roughly divided into mechanical and electromechanical control prostheses according to power classification. Many of them can realize different dimensions of activities or self-adaptation, have sensor feedback, brain wave control, and even mind control, etc. The degree of simulation is quite high. However, the use is often restricted by the power of the battery, and the grip strength is not easy to control, and the manufacturing process is complicated, and there are ...
