Description

Wireless charging locator based on implanted nerve stimulator Technical Field The application relates to the technical field of medical instruments, in particular to a wireless charging locator based on an implantable neurostimulator. Background The implanted nerve stimulator is widely applied to the treatment of parkinsonism, epilepsy, chronic pain, dyskinesia and other diseases. The device regulates the nerve function through electric stimulation, and improves the symptoms of patients. Implantable neurostimulators typically include a pulse generator with a battery and circuit module therein that requires periodic replenishment of electrical energy to maintain proper operation, and electrode leads. At present, the charging modes of the implanted nerve stimulator are mainly divided into two types of wired charging and wireless charging. The wired charging needs to be directly connected with the implanted device through a percutaneous puncture connecting wire, and the problems of infection risk and inconvenient operation exist. The wireless charging realizes energy transmission by utilizing the coupling between the external charging coil and the internal receiving coil through the electromagnetic induction principle, avoids the risk of percutaneous infection, and improves the use experience of patients. However, the existing wireless charging equipment still has the following technical problems that firstly, charging positioning is difficult, an external charging coil and an internal receiving coil are difficult to align accurately when a patient operates the wireless charging equipment by himself, so that charging efficiency is low and even charging cannot be achieved, secondly, an information communication function is lacked, state information such as electric quantity, temperature and impedance of the implanted equipment cannot be acquired in real time in a charging process, thirdly, electromagnetic compatibility is poor, an alternating magnetic field generated by the charging coil easily interferes with electronic elements such as a communication coil and a control circuit in the equipment, communication stability and equipment reliability are affected, fourthly, safety monitoring is insufficient, local temperature rise can be generated in the wireless charging process, an effective temperature monitoring and protecting mechanism is lacked, potential safety hazards exist, and thirdly, wearing and fixing are infirm, the equipment is easy to shift in the patient moving process, and charging effect is further affected.
