Solution Overview
Problem
Current multi-hole therapy techniques for skin treatments face challenges in accurately controlling needle depth and maintaining skin tension, leading to pain and uneven drug distribution, especially in older patients with reduced skin elasticity.
Innovation Solution
A module for skin surgery featuring a reciprocating assembly with screw-coupled movement and a guide suction assembly that provides tension and allows for precise control of needle depth through forward and backward rotation, minimizing pain and ensuring uniform drug distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If aestheticians manually fix needles into the skin depending on intuition, then the operation is simple, but the needle depth cannot be accurately controlled leading to pain and uneven drug distribution
Solution Approach 1:
The needle assembly is designed to move reciprocatingly between extended and retracted positions, allowing dynamic adjustment of needle depth. The reciprocating assembly enables the needles to be precisely positioned at desired depths while maintaining the ability to retract, solving the contradiction between depth control precision and operational simplicity.
Solution Approach 2:
The manual intuitive needle fixation method is replaced with a mechanical reciprocating system driven by a driving force. This substitution provides automated, precise depth control while reducing reliance on operator skill and intuition, thereby improving measurement precision without excessive complexity.
2Productivity
If multiple holes are perforated into the skin simultaneously, then productivity is improved, but it becomes difficult to retain proper skin tension especially in middle-aged patients with reduced skin elasticity
Solution Approach 1:
A vibration device is introduced to apply vibrational motion to the skin during the multi-hole perforation process. This vibration helps maintain proper skin tension and elasticity even when multiple holes are perforated simultaneously, preventing skin relaxation and ensuring consistent needle penetration depth across all holes.
3Reliability
If needles are pushed into the skin during perforation, then drug injection is achieved, but the needles slip or get stuck causing pain
Solution Approach 1:
The needles are pre-positioned in the reciprocating assembly at the desired penetration depth before contact with the skin. This preliminary positioning ensures that when the needles penetrate the skin, they maintain stable depth control and do not slip or get stuck, thereby reducing pain and improving reliability of the procedure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate and pain-reduced skin surgery by regulating needle depth and maintaining skin tension, ensuring effective drug penetration and distribution.
Implementation Method 1
the needles of the needle assembly are extended and contracted by the reciprocating assembly, which is screw-coupled inside the main body and moves forward and backward according to the forward and backward rotation
Implementation Method 2
because one end portion of the main body is closed, in the case that a device for providing vibration using a driving force is connected to the main body, the closed end portion of the main body provides proper tension while getting in contact with the skin

AI summary
The present invention relates to a module for use in skin surgery. The module for use in skin surgery includes: a main body, both sides of which are open and having an inner space; a reciprocating assembly which is built into the main body, and which can be moved forward and backward in the lengthwise direction of the main body through a screw-type coupling while the reciprocating assembly is rotated; a needle assembly built into the main body so as to contact the reciprocating assembly while enabling the reciprocating assembly to be rotated, wherein the needle assembly includes a plurality of needles which retract or extend through one end of the main body; and a guide suction assembly, one end of which contacts the skin such that each end of the needle is retracted or extended, and to which one end of the main body is coupled to enable the guide suction assembly to be rotated and contact the skin such that one end of the guide suction assembly is closely attached to the skin to thereby suction air.
