Background
Sacral nerve stimulator used in Sacral Nerve Modulation (SNM) is an active implantable medical device commonly used for treating diseases related to lower urinary tract dysfunction.
The sacral nerve stimulator comprises two components of a pulse generator and an electrode, wherein the pulse generator sends an electric pulse to the electrode and continuously applies the electric pulse to a specific sacral nerve so as to excite or inhibit a nerve channel and adjust abnormal sacral nerve reflex arcs, and then influences and adjusts the functions of sacral nerve innervated target organs such as a bladder, a urethra/anal sphincter, a pelvic floor and the like, thereby achieving the treatment effect.
The sacral nerve stimulator can be used for treating urgent micturition syndrome, urge incontinence, non-obstructive urinary retention, defecation dysfunction and the like, particularly overactive bladder, non-obstructive urinary retention, neurogenic bladder, interstitial cystitis, neurogenic intestine and the like, and is also commonly used for treating sexual dysfunction clinically.
Generally, when sacral nerve modulation is performed in some suitable patients, it is performed in two stages, i.e., two operations. The first operation can be referred to as the "experience" phase, i.e., the procedure of placement around the sacral nerve by puncture. The second operation is to place it under the skin through a small incision in the skin, which completes the sacral neuromodulation operation. In the experience period, the sacral nerve stimulation electrode needs to be implanted into the sacral 3 nerve hole, the electrode fixation is realized through four barbs on the electrode, the position of the electrode cannot be adjusted once the barbs are released, the outer sheath needs to be removed in the barb releasing process in the operation, the electrode displacement often occurs at the moment, and the electrode depth adjustment cannot be carried out due to the barb releasing, so that the operation curative effect is influenced.
