1. A submucosa treating apparatus comprising:
a probe for approaching mucosa of a treatment field;
an electrode provided in the probe having a quadrangle form, and applying an electrical signal to blood vessels of submucosa; and
a guide for guiding a position of the electrode with respect to the mucosa, and
wherein the probe is movably accommodated in the guide,
wherein a position of the guide with respect to the mucosa is fixed, and the probe is fully rotatable and straightly movable with respect to the guide,
wherein the guide comprises a referential position mark, and guides a rotation position of the electrode with respect to the mucosa with reference to the referential position mark, and
wherein the submucosa treating apparatus further comprises a guide portion for guiding rotation and straight-line movement of the probe with respect to the guide,
wherein the guide portion comprises
a guide groove formed in the probe, and
a guide protrusion formed in the guide and sliding along the guide groove,
wherein the guide groove comprises:
a linear guide groove that extends along a length direction of the probe at an outer surface of the probe; and
a plurality of rotation guide grooves that communicate with the linear guide groove and are spaced apart from each other along the length direction of the probe, and
wherein each of the plurality of rotation guide grooves extends along a circumferential direction of the probe at the outer surface of the probe,
wherein the plurality of rotation guide grooves are spaced apart from each other by a separation pitch along the length direction of the probe,
wherein the electrode has a horizontal length and a vertical length, the horizontal length being parallel to the length direction of the probe,
wherein the separation pitch is equal to the entire horizontal length of the electrode.
