Description

Multi hole medical instrument capable of simultaneous injection of chemicals

The present invention relates to a multi-hole surgery machine, and more particularly, to a multi-hole surgery machine capable of simultaneously injecting a drug solution that can simultaneously perform skin perforation and drug injection in a single operation.

In general, human skin is divided into epidermal (epidermal) layer, dermis (endodermal) layer and subcutaneous tissue layer. Of these, the dermis is filled with collagen and elastin, etc. The amount of collagen and elastin decreases gradually as the body ages. As a result, areas where the amount of collagen and elastin are relatively reduced are thinned and the skin layer is dried, or the elasticity of the skin is reduced to cause wrinkles.

Therefore, in the past, in order to maintain elastic skin, a method of directly applying various nutritional substances such as collagen and elastin, such as collagen and elastin, has been used to infiltrate the dermis into the dermal layer.

However, the amount of nutrients applied to the skin through the above method penetrates the epidermal layer and penetrates into the dermis layer is only a very small level, and there is no limit to improving wrinkles or giving elasticity to the skin.

In order to overcome these limitations, in recent years, a method of applying nutrients to the epidermal layer and then stabbing with a needle so that the nutrients are introduced into the dermis is used.

However, the method of applying nutrients to the epidermal layer and using the needles has a problem that the ratio of nutrients penetrating into the dermal layer is low, and the time required for introducing nutrients takes a long time.

In addition, when nutrients are applied to the surface of the epidermal layer after artificially forming pores in the epidermal layer and the dermis layer, the skin basically has a function of protecting the wound area from the outside through regeneration when a wound occurs. Even if artificial holes are formed, the holes are immediately blocked, and the amount of nutrients absorbed into the dermis layer through the holes is very small.

After that, when the spring 213 is restored and the cylinder body 211 retreats, a strong vacuum pressure is generated in the cylinder body 211. As the check valve is opened, the chemical liquid contained in the chemical storage container 100 connected to the cylinder body 211 is forcibly sucked into the cylinder body 211.

On the other hand, it may further include an outer casing 500 for receiving the chemical liquid storage container 100, the chemical liquid supply unit 200 and the needle drive unit 400. In this case, an iontophoresis terminal 510 may be further installed at the rear end of the outer casing 500.

Here, the iontophoresis is to increase the skin permeation of the ionized chemical solution by changing the electrical environment of the skin by applying a potential difference to the skin by using a galvanic current. It can be used to get the effect of penetrating the skin deeper into the skin.

In addition, the front end portion of the outer casing 500 may further include a perforation depth adjusting unit 600 to adjust the depth of the multi-holes formed in the skin.

The drilling depth adjusting unit 600 includes a rotating cover 610, a rotating housing 620, a lifting member 630, and a guide 640.

The second locking groove 622 is inserted into the outer surface is formed. Due to the coupling structure, when the rotary cover 610 rotates forward and backward, the rotary housing 620 coupled to the inside of the rotary cover 610 also rotates forward and backward.

In addition, the lifting projection 623 is formed on the inner surface of the rotating housing 620 is inserted into the spiral lifting groove 633 formed on the outer surface of the lifting member 630 to be described later.

The elevating member 630 is accommodated inside the rotary housing 620 in a hollow shape in which the upper and lower sides are opened. In addition, the upper and outer surfaces of the guide groove 641 formed on the lower inner surface of the guide 640 to be described later is inserted and detached groove 631 is formed. Then, the outer surface is formed with a spiral spiral lifting groove 633 is inserted into the lifting projection 623 formed on the inner surface of the rotating housing 620.

The guide 640 is a hollow shape in which the top and bottom are open, and the needle module 300 is disposed in the guide 640 in the arrangement. The guide 640 serves to guide the skin needling of the needle module 300 which is linearly reciprocated while the upper end is in contact with the skin. Then, the guide protrusion 641 is inserted into the removable groove 631 formed on the upper outer surface of the elevating member 630 is formed on the lower inner surface.

That is, the guide protrusion 641 is inserted into the detachable recess 631 through the opening of the detachable recess 631, and then rotate the guide 640 in one direction so that the guide 640 is seated on the lifting member 630. It is coupled to the lifting member 630. This coupling structure allows the replacement of the guide 640.

Looking briefly at the operating state of the drilling depth adjustment unit 600 made of the above-described components.

When the user rotates the rotary cover 610 in one direction, the lifting projection 623 is moved along the spiral lifting groove 633, the lifting member 630 is lowered inside the rotating housing 620 by this movement. Done. Due to the lowering of the elevating member 630, the guide 640 seated on the upper surface of the elevating member 630 is also lowered, and the needle module 300 located inside the guide 640 is relatively open of the guide 640. It is drawn out through the upper surface.

On the contrary, when the rotary cover 610 is rotated in the opposite direction, the lifting projection 623 moves in the opposite direction along the spiral lifting recess 633, and the lifting member 630 is moved inside the rotating housing 620 by this movement. Will rise. Due to the lifting of the elevating member 630, the guide 640 seated on the upper surface of the elevating member 630 is also raised, and the needle module 300 positioned inside the guide 640 is relatively inside the guide 640. It will be in descending form.
