Erectile Dysfunction (ED) is the most common male sexual dysfunction, which seriously affects the quality of life of patients. ED refers to the performance of the penis that can not be erect, or erection, but the erection is not strong, or the erection can not be maintained, so that sexual intercourse cannot be completed, also known as impotence.

Penile erection is a vascular response under neurological and endocrine regulation. The nerves that control the erection and relaxation of the penis are mainly sympathetic and parasympathetic. When the parasympathetic nerve is excited, the cavernous body and vascular smooth muscle relax, and blood flow increases, resulting in penile erection. The parasympathetic nerve originates from the medial lateral neurons of the parasympathetic nucleus (S2-4) of the medulla, and the anterior nerve fibers enter the pelvic plexus through the pelvic nerve, and then the corpus cavernosum branches to the penis, which causes the penile erection, so the cavernous nerve Also known as the erectile nerve.

It can be seen from the above that the penile erection is finally achieved by the stimulation of the cavernous nerve. Therefore, under the premise that the cavernous nerve is not damaged, the stimulation of the cavernous nerve is a means of treating ED. At present, a solution for treating ED is to make drugs for the cavernous nerve to excite the cavernous nerve, but the drug stimulation method takes an hour or longer to take effect, and it may cause side effects such as abnormal vision, headache, and diarrhea.

At this time, the two electrodes 31 corresponding to any two of the strips 320 serve as a positive electrode and a negative electrode, respectively. By providing a potential difference between the two sheet members 320, a current loop is formed in the cavernous nerve between the two sheet members 320, the two electrodes 31 connected thereto, and the two electrodes 31, in the cavernous nerve With the passage of electric current, the excitation stimulation of the cavernous nerve is realized.

In FIG. 2, the number of wires 33 and sheets 320 is merely an example. As a variant, the number of wires may be at least two, and the number of the plate members is also at least two, the sheet members and the wires are in one-to-one correspondence and the sheet members and the corresponding wires are electrically connected. In this way, it is possible to select a potential difference between the two sheet members to achieve an electric current in the cavernous nerve, thereby achieving the purpose of electrical stimulation of the cavernous nerve.

Referring to FIG. 2, the strip-shaped film 30 has a first end 301 and a second end 302 along the length direction. The first end 301 is an end provided with an electrode 31, and the second end is an end provided with an electrical connection member 32. The first end 301 is provided with two through holes penetrating the surface of the film 30 and spaced apart from each other along the length direction of the film 30, respectively being a first through hole 303 and a second through hole 304.
