Embodiment Construction

[0026] The present invention will be described in further detail below by means of specific embodiments:

[0027] The present invention proposes a method for reconstructing the sensory nerve function of the upper limb after amputation based on targeted sensory nerve distribution reconstruction. The specific implementation is described in detail in conjunction with the drawings as follows:

[0028] As an existing technology, the "Sabolich sensory system for lower limbs" developed by NovaCare National Prosthetics Research Center in the United States places pressure sensors on the toes and heels of prosthetic legs, and the sensors transmit surface pressure signals of different intensities to the stumps of the lower legs. The stimulating electrode is used to transmit the pressure signal by stimulating the surface skin of the stump of the calf. For the feeling of the prosthetic hand, the "Sabolich" system uses a clasp to wrap around the residual part of the affected limb. When the f...

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...
