Description

Technical Field

[0001] The utility model relates to the technical field of nerve stimulator devices, in particular to a nerve stimulator device which is easy to fix. Background Art

[0002] Many studies have shown that stimulating the ventral root of the sacral nerve can affect the action of the bladder detrusor and the external urethral sphincter, so that the use of appropriate stimulation signals can inhibit the hyperreflexia of the bladder detrusor and achieve the purpose of relieving urinary incontinence. An external sacral nerve stimulator is a programmable device that transmits stimulation through one or more electrode wires. It usually includes electrodes, electrode wires, external wiring terminals, connecting wires and program-controlled equipment, that is, the electrodes are implanted in the buttocks and contact the sacral nerves and connected to the external wiring terminals via electrode wires, and then the external wiring terminals are connected to the program-controlled equipment through connecting wires. The program-controlled equipment is equipped with a stimulation generator, and the stimulation setting values ​​are stored in its program. A program is a specific combination of pulse width, power and amplitude setting values ​​acting on a special composite electrode. In this way, the stimulation generator of the program-controlled equipment sends an electrical pulse signal to the sacral nerve, regulates the bladder and intestinal nerve reflexes related to urination and defecation, and restores the abnormal nerve reflexes to balance. The patient can control the switch and program setting of the stimulation generator through the external program-controlled equipment, so that the symptoms of urination and defecation dysfunction are controlled.

[0003] In actual use, the electrode wiring is usually a fixed-length wire. When carrying it with you, the wire needs to be stored separately. When using it, the wire needs to be taken out to connect the main body of the programmable device and the external terminal of the electrode in the body, which is inconvenient to use and not easy to fix and carry.
