Abstract

A submucosa treating apparatus according to an exemplary embodiment of the present invention includes: a probe that is capable of approaching mucosa of a treatment field; an electrode that is provided in the probe, and applies an electrical signal to blood vessels of submucosa; and a guide where the probe is movably accommodated, and a guide where the probe is movably accommodated, and guiding a position of the electrode with respect to the mucosa.

Claims (40)

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.

2. The submucosa treating apparatus of claim 1 , wherein the guide comprises:

a body portion where a first accommodation hole in which the probe is rotatably accommodated is formed; and

an expanded portion that communicates with the first accommodation hole and where the probe is rotatably accommodated, and is formed while integrally expanding from the body portion.

3. The submucosa treating apparatus of claim 1 , wherein the plurality of rotation guide grooves comprise first, second, and third rotation guide grooves that continuously neighbor each other, and

the linear guide groove comprises

a first section guide groove formed between the first rotation guide groove and the second rotation guide groove, and

a second section guide groove formed between the second rotation guide groove and the third rotation guide groove, and disposed on a line different from the line where the first section guide groove is disposed along the length direction of the probe.

4. The submucosa treating apparatus of claim 1 , comprising a plurality of restraining grooves formed in the guide groove, and

wherein the guide protrusion is accommodated while being position-fixed in the plurality of restraining grooves.

5. The submucosa treating apparatus of claim 4 , wherein the plurality of restraining grooves are formed in the rotation guide groove and spaced apart from each other along a circumferential direction of the probe.

6. The submucosa treating apparatus of claim 5 , wherein the plurality of restraining grooves are spaced from each other by as much as a length of the electrode along the circumferential direction of the probe.

7. The submucosa treating apparatus of claim 4 , wherein a pair of cut-out portions are formed along the length direction of the probe at an end of the body portion, and are distanced from each other along the circumferential direction of the probe, and

the guide protrusion is disposed at a free end of a cantilever structure formed by the pair of cut-out portions.

8. The submucosa treating apparatus of claim 1 , comprising a position-mark formed in the probe, and indicating a position of the probe with respect to the guide.

9. The submucosa treating apparatus of claim 1 , wherein

the electrode is mounted to partially cover an outer surface of the head portion while having a size smaller than the head portion, and

the outer surface of the electrode is curved such that the electrical signal is emitted in a radial shape through the curved surface of the electrode.

10. The submucosa treating apparatus of claim 1 , wherein the electrode comprises:

an electrode pad attached to the probe; and

an electrode protrusion protruding from an outer surface of the electrode pad.

11. The submucosa treating apparatus of claim 1 , comprising a coating layer formed at the outer surface of the electrode, the coating layer suppressing thermal conduction to the mucosa from the electrode.

12. The submucosa treating apparatus of claim 1 , wherein the electrical signal is a pulse signal that is iteratively conducted while having at least one delay time.
