Treatment apparatus and method of controlling same

1. A treatment apparatus, comprising:

a handpiece;

an RF generator generating RF energy;

an insertion unit configured to advance and retract toward one direction of the handpiece, selectively inserted into a tissue, and electrically connected to the RF generator to transfer the RF energy to an inside of the tissue;

a substance storage unit receiving a therapeutic substance therein and detachably installed on one side of the handpiece to transfer the substance to the inside of the tissue by the advancing operation of the insertion unit; and

a controller controlling operations of the RF generator and the insertion unit, wherein the controller differently controls the advancing and retracting operation of the insertion unit depending on whether the substance storage unit has been installed,

wherein the controller controls the advancing and retracting operation of the insertion unit in a first mode in which the substance storage unit has not been installed, and in a second mode in which the substance storage unit has been installed,

wherein, in the first mode, an end of the insertion unit is inserted into the tissue when the insertion unit advances, and the end of the insertion unit is received within the handpiece when the insertion unit retracts, and

wherein, in the second mode, the end of the insertion unit is inserted into the tissue when the insertion unit advances, and at least a part of the insertion unit is received within the substance storage unit when the insertion unit retracts.

2. The treatment apparatus of claim 1 , wherein:

the substance storage unit is positioned on a path along which the insertion unit moves while the insertion unit performs the advancing and retracting operation, and

the insertion unit is inserted into the tissue through the substance storage unit when performing the advancing operation.

3. The treatment apparatus of claim 2 , wherein the insertion unit is inserted into the tissue in a state in which the substance has been applied on an external surface of the insertion unit while the insertion unit penetrates the substance storage unit.

4. The treatment apparatus of claim 1 , wherein the substance is transferred from a surface of the tissue to a depth into which the end of the insertion unit is inserted along a path formed within the tissue by the insertion of the insertion unit.

5. The treatment apparatus of claim 1 , wherein the insertion unit operates to transfer the RF energy after the substance is transferred to the inside of the tissue.

6. The treatment apparatus of claim 1 , wherein an external surface of the insertion unit has a structure in which prominences and depressions are formed in order to improve transfer efficiency of the substance to the inside of the tissue.

7. The treatment apparatus of claim 1 , further comprising an installation sensing unit sending whether the substance storage unit has been installed, wherein the controller differently controls the advancing and retracting operation of the insertion unit based on information sensed by the installation sensing unit.

8. The treatment apparatus of claim 1 , wherein, in the second mode, the insertion unit is additionally advanced as much as a length corresponding to a thickness of the substance storage unit compared to the first mode.

9. The treatment apparatus of claim 1 , wherein the substance received in the substance storage unit has a gel form.

10. The treatment apparatus of claim 1 , wherein at least one surface of the substance storage unit through which the insertion unit penetrates has a membrane structure having viscoelasticity so that a leakage of the substance through a through hole formed by the advancing and retracting operation of the insertion unit is minimized.

11. The treatment apparatus of claim 1 , wherein the substance storage unit further comprises a marking part indicating whether the substance storage unit is used when the substance storage unit is coupled to the handpiece.

12. A method of controlling a treatment apparatus, comprising steps of:

installing a substance storage unit in which a therapeutic substance is received on one side of a handpiece;

advancing a plurality of insertion units to a substance storage unit so that the substance is applied on external surfaces of the insertion units provided in the handpiece;

inserting the insertion units applied with the substance into a tissue by advancing the insertion units through a surface of the tissue;

transferring RF energy to an inside of the tissue through the insertion units;

retracting the insertion units so that the insertion units exit from the tissue and ends of the insertion units are located within the substance storage unit, and

moving the handpiece to a different position, and,

inserting the insertion units, which are positioned in the substance storage unit, into another tissue located in the different position.

13. The method of claim 12 , further comprising a step of sensing whether the substance storage unit has been installed.

14. A method of controlling a treatment apparatus, comprising steps of:

sensing whether a substance storage unit in which a therapeutic substance is received has been positioned on one side of a handpiece to which an insertion unit advances;

setting the insertion unit in a first mode in which the insertion unit is advanced as much as a first length and transfers RF energy when the substance storage unit is sensed to have not been installed; and

setting the insertion unit in a second mode in which the insertion unit is advanced as much as a second length longer than the first length and transfers RF energy when the substance storage unit is sensed to have been installed,

wherein, in the second mode, at least a part of the insertion unit is received within the substance storage unit when the insertion unit retracts.

15. A treatment method using a treatment apparatus, comprising steps of:

installing a substance storage unit in which a therapeutic substance is received on one side of the handpiece through which an insertion unit advances and retracts;

advancing the insertion unit to the substance storage unit and applying the substance on an external surface of the insertion unit;

inserting the insertion unit applied with the substance into a tissue and transferring the substance to an inside of the tissue;

transferring RF energy to the inside of the tissue using the insertion unit; and

retracting the insertion unit so that the insertion unit exits from the tissue and at least a part of the insertion unit is located within the substance storage unit.
