Description

A charger external fixation device

technical field

The invention relates to the technical field of accessories for medical devices, in particular to an external fixing device for a charger.

Background technique

Deep brain stimulation (DBS) is a type of implantable neurostimulation. It has significant curative effects in a variety of refractory neurological diseases. It has become the standard therapy for Parkinson's disease. It is widely used in sexual disorders, and has broad application prospects in mental diseases such as obsessive-compulsive disorder and depression.

Sacral Nerve Stimulation (SNM) is to act on specific sacral nerves through short-frequency pulse stimulation current, artificially activate excitatory or inhibitory neural pathways, thereby regulating the functions of the bladder, external urethral sphincter and pelvic floor muscles, helping Treatment of voiding dysfunction.

Spinal cord stimulation (SCS) is a treatment that improves chronic intractable neuropathic pain by stimulating the spinal nerves with weak electricity. In 2013, my country's "Expert Consensus on the Diagnosis and Treatment of Neuropathic Pain" recommended that electrical spinal cord stimulation can be used for the treatment of failed back surgery syndrome, complex regional pain syndrome, adhesive arachnoiditis, peripheral Neuropathic pain, stump pain, and angina pectoris for which immediate surgery is not possible.

Vagus nerve stimulation (VNS) is an effective method for the treatment of intractable epilepsy. Compared with craniotomy for drug-refractory epilepsy, it has the advantages of no craniotomy, less trauma, and faster recovery.

Implantable medical devices such as DBS, SNM, SCS, VNS, etc. are implanted into the patient's body, and there are tissues such as skin between the external charging device and the external charging device. Usually, the charging is performed wirelessly. This wireless charging method usually uses the external wireless charging coil and the internal body. The power receiving coil of the implanted medical device transmits power by means of electromagnetic coupling. The implanted medical device needs to be charged regularly. When charging, the wireless charging coil and the pulse generator of the implanted medical device must be aligned accurately and stably so that the charging can be performed normally. If there is no auxiliary tool, the patient has to hold the coil with his hand and stick it in front of the pulse generator during charging, and keep it motionless for several hours, which is very painful for the patient and difficult to complete the work, and it is easy to pay attention to it. Displace the wireless charging coil and affect the normal charging.
