Embodiment Construction

[0014] Fig. 1 is the perspective view of an embodiment of the simulation electronic prosthetic hand of the present invention, as seen from the figure, this simulation electronic prosthetic hand comprises a wrist joint 1, a palm seat 2 that links to each other with the prosthetic wrist, a thumb 3, a finger frame 4 , a DC motor 5, wherein the thumb 3 is fixed on the palm base 2, and the finger frame 4 is located on one side of the finger frame shaft 4a, opposite to the thumb 3, the DC motor 5 is fixed on the palm base 2, and its motor shaft After being decelerated, a gear 5a meshes with the sector gear 6 on the finger frame shaft 4a. See Figure 2. Under the control of myoelectricity, the patient can make the motor 5 rotate forward or reverse according to his own wishes, so as to realize palm-to-palm movement, perform operations such as fetching and holding objects. The artificial hand is characterized in that it is structurally the same as the real hand, and has 14 joints in to...

Abstract

A simulated electronic prosthetic hand, comprising a wrist joint, a palm seat connected with the prosthetic wrist, a thumb, a finger frame, and a miniature DC motor. three joints. The thumb joint is composed of two fixed splints on one finger clamping a joint ball with a handle; the joints of the other four fingers are composed of two parallel fixed plates on one finger and two fixed plates on the other finger. It consists of a moving plate, in which the fixed plate and the moving plate are fixed with fastening bolts. The wrist joint comprises a seat board fixedly connected with the palm seat, a pressing plate, and a joint ball fixedly connected with the false forearm to form a universal joint. Each joint of the described prosthetic hand can properly adjust the relative position (angle) between each joint with the help of the healthy hand. Similarly, its wrist joint can also properly adjust the angle with the help of the healthy hand, so as to realize quasi-two free artificial hands. The function, coupled with plastic gloves, its shape resembles a real hand.

Description

[0001] Technical field: The present invention relates to a prosthetic body for rehabilitation, and specifically refers to an improvement of an electronic artificial prosthetic hand. Background technique: [0002] Due to many factors such as traffic accidents, natural disasters, industrial injuries, wars and congenital diseases, there are many patients with disabled limbs. According to statistics, there are tens of millions of patients with residual limbs all over the world. In order to allow people with disabled limbs to take care of themselves and improve their quality of life as much as possible, various prosthetic hands have emerged in recent years. Electronic prosthetic hands are welcomed by people with disabled limbs because they rely on external energy supply and cooperate with bioelectric control to realize control according to people's wishes. [0003] The current electronic prosthetic hand simplifies the four fingers into two pieces, which are opposite to one piece o...
