Description

Jig for manufacturing needle assembly and method for manufacturing needle assembly using the same

The present invention relates to a jig for manufacturing a needle assembly and a method for manufacturing a needle assembly using the same, and more particularly, to a jig for manufacturing a needle assembly for manufacturing a needle assembly including a plurality of needles, and a method for manufacturing a needle assembly using the same .

When a high-frequency current is passed through the body, deep heat is generated in the human tissue. Deep heat is biothermal heat generated by rotational motion, twisting, collision motion, etc. as molecules constituting human tissue vibrate and rub against each other by high-frequency electrical energy.

Recently, as a method for skin treatment such as acne treatment, pore reduction, wrinkle removal, and scar removal, a high-frequency treatment device using a micro needle as an electrode has been developed and used.

The high frequency treatment device allows the microneedle to pass through part or all of the epidermal layer to reach the dermal layer, thereby allowing the high frequency current to flow smoothly even in the dermal layer, thereby improving treatment efficiency.

In general, a high-frequency treatment device using a microneedle is a high-frequency oscillator that generates a high-frequency current, a supply line that is drawn from the high-frequency oscillator to supply a high-frequency current, a handpiece connected to the supply line, and a handpiece connected to the handpiece to contact the skin and a needle tip into which a plurality of microneedles are inserted. The needle tip into which the microneedles are inserted consists of a plurality of microneedles fixed to the needle support plate, and a printed circuit board is coupled to the needle support plate so that a high-frequency current is supplied to each microneedle.

Since a plurality of microneedles are simultaneously inserted into the skin in a radiofrequency treatment device using a microneedle, the microneedle must be fixed to the needle support plate so that each microneedle has a constant height. To this end, a needle support plate is placed on a jig, a needle is inserted through a hole formed in the needle support plate so that the tip of the microneedle touches the jig, and the rear end of the microneedle exposed in a predetermined portion on the needle support plate is soldered. The needle tip is completed by inserting the needle assembly, in which the microneedle is fixed to the needle support plate, into the housing.

However, in the needle tip manufactured in this way, in the process of soldering to fix the microneedle to the needle support plate, the needle is pulled due to the cohesive force in the liquid state in which the lead is melted, so that the position of the tip of the plurality of microneedles is different. There are concerns.

On the other hand, the radiofrequency treatment device including the microneedle is made to pass the microneedle through the stratum corneum of the skin to deliver the radiofrequency energy to the depth of the dermal tissue to treat the skin. At this time, since the microneedle generally penetrates to a skin depth of 2 to 5 mm and operates, considerable pain may be induced. Therefore, before treatment, after applying an anesthetic cream, treatment is performed using a radiofrequency treatment device.

As described above, when the dermal layer penetrates to the depth where high-frequency energy is applied, the pain increases according to the depth. Methods to obtain the effect are being studied. However, in order to perform a procedure at a depth of 0.3 mm or less, the tip of each needle must be precisely positioned at the same position during the manufacture of the needle tip. Skin pain increases.

In the present embodiment, the plurality of support holes 20a are arranged in 5 rows and 5 columns, but the present invention is not limited thereto and may be arranged in various numbers of matrices. In another embodiment, the plurality of support holes 20a may be arranged in a row according to the purpose of use.

The rear end 12 of the needle is fixed to the support hole 20a of the needle support plate 20 to form the needle assembly 30 .

In an embodiment of the present invention, the needle support plate 20 has a unit support hole 40 region made of a PCB substrate so that current can be supplied to each needle 10 .

In another embodiment of the present invention, the needle support plate 20 is made of a non-metallic material, such as plastic, in which the unit support hole 40 region is made of a metal material and the needle 10 is welded together, or in another way. The needle 10 may be coupled in a manner using molding or an adhesive.
