The utility model optimizes the fixing structure of the electrode, so as to facilitate the position adjustment of the electrode at the position of the window 11. By adopting the combination of the electric needle 4 and the electrode sheet 3 as the stimulation electrode, it is convenient to switch the electric needle 4 or the electrode sheet 3 for electrical stimulation. It meets different stimulation needs. The provision of the insulating sleeve 5 facilitates the electric needle 4 to pass through the through hole for guidance.

[0030] The sub-fixing belt is a cross-shaped belt formed by the intersection of two belt-shaped bodies. The electrode sheet is fixed at the intersection of the two belt-shaped bodies. Both belt-shaped bodies are detachably connected to the periphery of the window. The sub-fixing belt can be moved to different positions left and right, front and back, to adjust the position of the electrode sheet in the window area.

[0031] An insulating ring is fixed to the outer edge of the electrode sheet 3, and the insulating ring is connected to the sub-fixing belt 2 through an adhesive. The insulating ring can be a silicone ring.

[0032] The bottom of the insulating sleeve 5 is provided with a tapered guide portion whose outer wall is narrow at the bottom and wide at the top, so as to facilitate the insulating sleeve 5 to extend into the through hole.

[0033] The electrode sheet 3 is provided with a terminal extending upward. The electrode sheet 3 includes a sheet-like substrate and an annular cylinder, and the sheet-like substrate and the annular substrate are provided with through holes that are connected to each other. The inner diameter of the through hole of the annular substrate is larger than the inner diameter of the through hole of the sheet-like substrate.
