Method for reconstructing sensory nerve functions of amputation upper limbs and method for sensory nerve and artificial limb interfaces

Abstract

The invention discloses a method for reconstructing sensory nerve functions of amputation upper limbs and a method for reconstructing sensory nerve and artificial limb interfaces.The method for reconstructing the sensory nerve functions of the amputation upper limbs includes steps of separating sensory branches of various nerve bundles of remaining brachial plexus nerves of amputation patients and connecting the nerve sensory branches with sensory nerves in target sensory regions; adding different sensory sensors into nerve artificial limbs, timely transmitting external stimulation in contact with the artificial limbs to the target sensory regions of the limbs of the amputees by the aid of a stimulation input process and further transmitting the external stimulation in contact with the artificial limbs to sensory center regions of the brains of the amputees by the aid of the reconstructed target sensory regions of the limbs.The methods have the advantages that the brachial plexus nerves remained after the upper limbs of the amputation patients are amputated are connected into the selected target sensory regions, sensory innervation regions of the limbs can be reconstructed in the target sensory regions by the brachial plexus nerves, the limb sensory functions lost due to amputation can be reconstructed, and accordingly interfaces functions of remaining limb sensory and multifunctional nerve artificial limb sensory can be implemented.

Description

technical field [0001] The invention relates to a method for a prosthesis that can be transplanted into the body, in particular to a method for reconstructing the sensory nerve function of an amputated upper limb and a method for reconstructing the interface between the sensory nerve and the artificial limb. Background technique [0002] The sensory control system of multifunctional neuroprosthetics generally uses visual feedback to adjust the movement of the prosthesis, which is prone to fatigue, and the information provided by the vision is incomplete, the movement mechanics, coordination and accuracy are poor, and the error rate is high. With the development and application of new technologies, people use various advanced sensing technologies to solve the problems existing in the sensory feedback of prosthetic limbs. Many scholars and prosthetic research teams at home and abroad have designed and developed multifunctional artificial prosthetics and components with certain...

Problems solved by technology

[0006] The present invention intends to provide a method for reconstructing the sensory nerve function of the amputated upper limb and a method for reconstructing the interface between the sensory nerve and the prosthetic limb, so as to solve the problem that the nerve function reconstruction method after the existing upper limb nerve function damage can only solve the local motor function of the upper limb, while for the missing limb For the sensory function of the upper limbs, due to the loss of the skin, muscles, nerves and other structures of the upper limbs, the above nerve function reconstruction methods cannot be applied in sensory function reconstruction, and there is no shortage of limb sensory nerve function reconstruction methods specially suitable for amputee patients
