Degradable flexible nerve tract repair device

Abstract

The invention relates to a degradable flexible nerve repair device. The device includes a flexible base for carrying a nerve repair electrode, an energy receiving coil and a connecting wire; the connecting wire can connect the energy receiving coil and the nerve repair electrode together; the energy receiving coil is used for generating induced current when an electromagnetic wave corresponding tothe self resonance frequency is received; the flexible base includes a nerve tract fixing part corresponding to the nerve repair electrode, and the nerve tract fixing part and the nerve repair electrode are wound on a nerve tract to be repaired together, and the nerve repair electrode makes contact with the nerve tract to be repaired; the nerve tract fixing part is used for fixing the nerve tractto be repaired; the nerve repair electrode is used for transferring the received current to the nerve tract to be repaired. The device provided by the embodiment of the invention is degradable in anorganism, has little side effect on the organism, accelerates the treatment and repair process of the nerve tract, has good flexibility and ductility, and cannot bring inconvenience to the life and work of the organism.

Description

technical field [0001] The present disclosure relates to the technical field of flexible electronics, in particular to a degradable flexible nerve repair device. Background technique [0002] Nervous disease is a relatively important disease in human health. Since most nerves have a self-repair process, studies have shown that in the process of nerve repair, certain electrical stimulation can accelerate the process of nerve repair. In the field of traditional medical devices, Kraft electrodes, utah electrodes, and Michigan electrodes are all made of traditional hard materials. These materials have a large mechanical mismatch with human tissues. Therefore, when implanted in the human body, not only There is a large mechanical mismatch, and it is difficult to form a good conformal fit contact with human tissue under the condition of small trauma. At the same time, because the traditional electrodes are made of non-degradable materials in vivo, and there are multiple lead wire...

Problems solved by technology

These problems have brought great difficulties to the development of medical devices for nerve repair

Due to the way of cable power supply and communication, traditional electrical stimulation devices often need to lead out several cables from the body during work, which brings great difficulties to the closure of wounds; at the same time, due to the non-degradable materials, traditional medical treatment After the functional application of the device is completed, it needs to be taken out by surgery for a second time, which brings a series of complications to the patient. The secondary tissue damage, infection, and inflammation caused by the second surgery may even endanger the life of the patient.
