Implantation type wireless limbs sport control nerve stimulation network system and control method

Abstract

The invention requests to protect an implantation-type nervous stimulation system of controlling wireless limb motions and a control method thereof, which relates to a technical field of human implantation-type medical devices. The system makes use of the principle of advanced wireless sensing network technology, constructs a star-type network and not limits to a wireless stimulation network of star-type network topology, and the topological structure is flexible and the extensibility is strong, and stimulation networks with different scales are constructed according to requirements of controlling of different limb motions; by adopting a wireless time synchronous protocol and the coordination work of synchronous dormancy and synchronous awaking of an external control terminal and an internal stimulation unit, the system realizes a multi-target implantation-type nerve stimulation method of wireless limb motion controlling, and the Burst working mode is low in power consumption and can prolong the service life of the internal stimulation unit greatly. The system and the control method thereof provide a novel stimulation device and a control method for the recovery treatment of nervous system diseases or patients of nervous system injury, and are beneficial to realize the controlling over more coordinate and natural limb motions in low trauma through the wireless synchronous controlling stimulation of multiple nerves and multiple muscles.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an implanted nerve stimulation network system for treating nervous system diseases or injuries and a control method thereof. technical background [0002] In the rehabilitation treatment of certain motor nervous system diseases and nerve injuries, functional nerve electrical stimulation is often used clinically for treatment. Functional nerve electrical stimulation is based on the mechanism of human voluntary movement. By applying repetitive pulse electrical stimulation signals, the nerve response is used to transmit additional artificial control signals, thereby generating nerve impulses that are exactly the same as natural excitation, so that the decayed nerves can be reconstructed or Restoring function to achieve the purpose of treatment or functional rehabilitation and reconstruction. [0003] With the development of biology, electronics, materials and other disc...

Problems solved by technology

However, point-to-point communication is used between the external controllers of these implanted stimulation systems and the implanted stimulators in the body, which can only stimulate a single nerve or local muscle, and cannot be applied to limb movement control that requires multi-channel and multi-target stimulation. nerve stimulation

[0004] For the nerve stimulation system with multi-channel and multi-target stimulation for limb movement control, the multi-channel stimulation design based on surface electrodes is still mainly used at present. This type of system has complex structures and large stimulation currents, which often cause discomfort and pain for patients.

In recent years, the implantable limb movement control nerve stimulation system that is being developed all uses a single control unit in the body to connect the stimulation electrodes of each target point through wires. This system requires many wires. At the same time, the scope of implantation operation is large, the degree of trauma is high, and it is also prone to failure due to wire breakage, causing unnecessary harm to patients
