Problems solved by technology

However, with the patient's physical activity, the stimulating electrode may be displaced within the body tissue, thereby affecting the therapeutic effect of electrical stimulation
Although the prior art provides various fixing devices to prevent positional displacement of stimulating electrodes in body tissue (such as US7865250B2 (Medtronic), US8145323 B2 (Medtronic), US8260436 B2 (Medtronic), US8019443B2 (Boston Medical), Electrode displacement cannot be absolutely avoided
Moreover, when the stimulation electrodes are displaced, patients and doctors cannot immediately realize it, which will lead to a decline in the therapeutic effect

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0021] In one embodiment of the present invention, as Figure 1 to Figure 2 As shown, the present invention discloses an implantable neurostimulator with the function of prompting electrode displacement, and the implanted neurostimulator is an implanted neurostimulator, which is used to apply electrical stimulation to the target nerve area of ​​the patient . The implantable neural stimulator includes an external program controller 5, an implantable pulse generator 1 and a stimulating electrode 2, the implantable pulse gen...

Abstract

The invention relates to the field of implantable nerve stimulators, and particularly discloses an implantable sacral nerve stimulator with the electrode dislocation prompting function. The implantable sacral nerve stimulator comprises an external program controller, an implantable pulse generator (1) and a stimulating electrode (2). The implantable nerve stimulator further comprises an electric field intensity sensor (3). The electric field intensity sensor (3) is arranged at a target nerve (4). The electric field intensity sensor (3) monitors electric field intensity generated by the stimulating electrode (2). The electric field intensity sensor (3) transmits monitored data to the implantable pulse generator (1) or the external program controller (5). The stimulator further comprises a prompting device. When the implantable pulse generator (1) or the external program controller (5) monitors unusual data, a prompting signal is sent to the promoting device, and a prompt is enabled when the prompting device receives the prompting signal. The implantable sacral nerve stimulator can automatically prompt dislocation of the stimulating electrode, and the treatment quality can be ensured.

Description

technical field [0001] The invention relates to an implanted nerve stimulator, in particular to an implanted nerve stimulator with an electrode displacement prompting function. Background technique [0002] It has been reported that more than 13 million American men and women of all ages suffer from urinary and fecal incontinence. Social implications for people with incontinence include loss of self-esteem, embarrassment, restriction of social and sexual activity, isolation, depression, and, in some cases, dependence on caregivers. Incontinence is the most common reason older people are institutionalized. [0003] Sacral Anterior Root Stimulation is a neurostimulation device used to restore bladder function in patients with persistent spinal cord injuries. Its overstimulation electrodes deliver electrical stimulation signals to target nerves to improve incontinence symptoms. However, with the physical activity of the patient, the stimulating electrode may be displaced in ...
