Implanted bladder function repairing system

Abstract

The invention relates to an implanted bladder function repairing system, comprising an electrode, a nerve signal amplifier, a nerve signal processing circuit and a nerve electronic stimulator, wherein the electrode is fit with a sacral nerve root sleeve; the electrode is connected with the nerve signal amplifier and used for sending the nerve electrical signal received from a sacral nerve posterior root in the sacral nerve root sleeve to the nerve signal amplifier to be amplified; the nerve signal amplifier is connected with the nerve signal processing circuit and used for sending the amplified nerve electrical signal to the nerve signal processing circuit to be processed; the nerve signal processing circuit determines whether a human body needs to urinate according to the amplified nerve electrical signal, and sending a urinating signal to the connected nerve electronic stimulator if the human body needs to urinate; the nerve electronic stimulator sends a simulating electrical signal to the connected electrode according to the urinating signal; and the electrode stimulates the sacral nerve root sleeve by the simulating electrical signal to cause the sacral nerve in the sacral nerve root sleeve to control a bladder to urinate by the anterior root. The implanted bladder function repairing system can help patients to urinate as required.

Description

technical field [0001] The invention relates to the technical field of implantable medical electronic systems, in particular to an implantable bladder function restoration system. Background technique [0002] Spinal cord injury is a trauma that seriously endangers human health. The complications caused by it, such as neurogenic bladder, paraplegia, infection, and decubitus ulcer, seriously reduce the quality of life of patients and increase their medical expenses. In spinal cord injury, neurogenic bladder can cause long-term complications such as urinary tract infection and renal failure, and has become a major threat to the life and health of patients with spinal cord injury. [0003] figure 1 A schematic diagram of the nervous system associated with bladder voiding. Such as figure 1 As shown, the anterior root of the sacral nerve 102 and the posterior root of the sacral nerve 101 extend from the circular vertebra 103 in the human body. The end is connected to the blad...

AI Technical Summary

Problems solved by technology

[0005] For patients suffering from neurogenic bladder, the neural pathway between the bladder 105 and the cone 103 (i.e. figure 1 The posterior sacral nerve root 101, the anterior sacral nerve root 102, and the sacral nerve root sleeve 1012 formed by the confluence of the two) are not smooth, so that the above-mentioned nerve electrical signals or stimulation signals cannot be transmitted between the conical vertebra 103 and the bladder 105. Passed between the muscles, so patients can not urinate spontaneously, causing long-term urinary tract infection, renal failure and other complications

[0006] The existing bladder function repair system helps the patient to urinate by regularly stimulating the sacral nerve root cuff 1012, so the patient can only urinate at a certain time every day. When urinating, urinate in time, and there is no guarantee that the patient can excrete urine at the urination time determined every day (the patient may drink less water and have no urine)
