Embodiment Construction

[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0035] Such as figure 1 , figure 2 and image 3 As shown, the forearm amputee is taken as an example. The prosthesis 100 of one embodiment includes a receiving cavity 110, a first support plate 120, a strap 130, a second support plate 140, a drive shaft 150, a drive device 160, a sensor 170, and a control System 180.

[0036] The receiving cavity 110 is a funnel-shaped shell with both large and small ends open. Among them, the stump of the forearm 300 of the forearm amputee is housed in the big end of the receiving cavity 110. The small head end of the receiving cavity 110 forms a connecting joint 112, and the connecting joint 112 is fixedly connected to the artificial hand (not shown). For example, the connecting joint 112 is threadedly connected with the artificial hand, so that the artificial hand and th...

Abstract

The invention provides an artificial limb. The artificial limb comprises a receiving cavity, a first supporting plate, a bandage, a second supporting plate, a driving shaft, a driving device, a sensor and a control system. The receiving cavity is a funnel-shaped shell, wherein the big end and the small end of the receiving cavity are both open. One end of the first supporting plate is connected with the big end of the receiving cavity. The bandage and the receiving cavity are arranged in a spaced mode. The bandage is close to the big end of the receiving cavity. One end of the second supporting plate is fixedly connected with the bandage. The two ends of the driving shaft are connected with the end, far away from the receiving cavity, of the first supporting plate and the end, far away from the bandage, of the second supporting plate in a rotatable mode respectively. The driving device is electrically connected with the driving shaft and is used for driving the driving shaft to rotate. The sensor is used for collecting an electromyographic signal. The control system is electrically connected with both the driving device and the sensor and converts the electromyographic signal collected by the sensor into a driving signal after signal processing so as to control the driving device to operate. The artificial limb is not prone to disengagement and is good in load bearing capacity.

Description

【Technical Field】 [0001] The invention relates to an artificial limb. 【Background technique】 [0002] There are countless amputees caused by various disasters, especially arm amputees. As we all know, the hand is the most basic tool for us to create value and solve personal daily life. Many upper limb amputees choose to install prostheses to achieve simple arm and hand movements to assist in solving daily life needs. However, the direct contact area between the prosthesis receiving cavity and the limb and the weight-bearing capacity of the stump have not attracted enough attention. When the residual limb is used for long-term weight-bearing, the lighter one will easily cause the amputee’s prosthetic socket to fall off or loosen, and the heavy one will cause chronic blood circulation disorders for the prosthetic wearer, causing swelling of the stump, and even eczema, chronic ulcers and blisters Wait. Severe skin changes can make patients lose weight-bearing ability and cannot w...
