1. A method of manufacturing an extensible electrode array for accurately locating a pelvic floor muscle, comprising the following steps:
(1) obtaining a three-dimensional muscle anatomy map of a pelvic floor muscle, determining a target muscle group according to the three-dimensional muscle anatomy map and determining a muscle fiber trend, and for each muscle, determining a plurality of three-dimensional coordinate points for marking each muscle along the muscle fiber trend;
(2) setting up an expandable elastic cavity with reference to shape of a pelvic floor cavity, after projecting all three-dimensional coordinate points onto a two-dimensional plane unfolded in a shape of an elastic cavity, taking each two-dimensional coordinate point in the two-dimensional plane as a location to dispose an electrode plate;
(3) simulating a mechanical property of the elastic cavity under different expandable states, and determining a deformation rate of an extensible electrode wire of the electrode plate when the extensible electrode wire of the electrode plate is arranged along a muscle fiber direction of the pelvic floor muscle; and
(4) according to a designed location of the electrode plate, a wiring trend and the deformation rate of the extensible electrode wire, mounting the electrode plate and the extensible electrode wire on the elastic cavity to form the extensible electrode array for accurately locating a pelvic floor muscle, and ensuring that each electrode plate maintains precise fit with the target muscle when the expandable elastic cavity expands.
