Fig. 2 is the structural schematic diagram of needle electrode component.
Specific implementation mode
Illustrate the specific implementation mode of the present invention below in conjunction with attached drawing.
As shown in Figure 1, ring type rotational positioning pin type electromyographic electrode, including：Fixed ring 12, slip ring 11, multiple pin types electricity
Pole component 13 and air bag 14.
Fixed ring 12 is sleeved on the position of checking with EMG method.
Slip ring 11 is sleeved on the periphery of fixed ring 12, is rotatablely connected with fixed ring 12；Multiple needle electrode components 13, edge
The circumference of slip ring 11 is arranged, and the both sides of the edge of fixed ring 12 are nearby provided with two air bags 14 of concentric setting,
When air bag 14 is in inflated condition, the position of fixed ring 12 is fixed, and is along the circumferential direction provided in fixed ring 12 multiple
Electrode through-hole 32, needle electrode component 13 move in a circle with slip ring, match the electrode through-hole 32 of different location.Air pump (Fig. 1
