High frequency output device and invasive tip therefor

An invasive tip comprising:

• a substrate;
• a needle array extending from a first surface of the substrate;
• one or more conductive pins extending from a second surface of the substrate;
• a bracket for supporting the substrate and guiding the one or more conductive pins;
• a housing configured to accommodate the bracket inside thereof, the housing having a first end facing the first surface, a second end opposite to the first end, and a side wall formed to surround the needle array between the first end and the second end, the side wall having an inclination portion with a shape of an inclined surface whose horizontal cross-sectional area decreases from an inclination start position on the side wall to the first end, wherein the first end has a plurality of through holes formed therein;
• and
• an alignment plate formed with a hole therein and configured to support a bottom surface of the bracket,
• wherein the plurality of through holes is formed to be aligned with the needle array,
• the bracket is configured to be raisable and lowerable within the housing,
• the needle array is exposed to an outside of the housing or accommodated within the housing by passing through the through holes as the bracket is raised or lowered, and
• a penetration height of the needle array is limited by the side wall, on which the inclined surface is formed, when the needle array penetrates a person's skin;
• and
• wherein the alignment plate is fixed to the inside of the housing, and
• the bracket is accommodated in a space between the alignment plate and the inner wall of the housing, the space being partitioned and defined by the alignment plate.

A high frequency output device comprising:

• a main body for generating high frequency energy;
• and
• a handpiece for receiving the high frequency energy from the main body and transmitting the high frequency energy to an invasive tip,
• wherein the invasive tip comprises:
• a substrate;
• a needle array extending from a first surface of the substrate;
• one or more conductive pins extending from a second surface of the substrate;
• a bracket for supporting the substrate and guiding the one or more conductive pins;
• and
• a housing configured to accommodate the bracket inside thereof, the housing having a first end facing the first surface, a second end opposite to the first end, and a side wall formed to surround the needle array between the first end and the second end, the side wall having an inclination portion with a shape of an inclined surface whose horizontal cross-sectional area decreases from an inclination start position on the side wall to the first end, wherein he first end has a plurality of through holes formed therein,
• the plurality of through holes is formed to be aligned with the needle array,
• the bracket is configured to be raisable and lowerable within the housing,
• the needle array is exposed to an outside of the housing or accommodated within the housing by passing through the through holes as the bracket is raised or lowered,
• wherein the substrate comprises:
• a first substrate to which the needle array is fixed;
• and
• a second substrate disposed adjacent to the first substrate, and
• an insulating layer is inserted between the first substrate and the second substrate, and
• the handpiece comprises:
• an electrical circuit for providing the high frequency energy to the one or more conductive pins;
• and
• a pressing unit for generating a mechanical force to raise or lower the substrate within the housing.
