DESCRIPTION

Device for making incisions in hair transplant procedures

TECHNICAL SECTOR

The present invention refers to a device or manual instrument, specially designed to make incisions in the skin, which subsequently allows hair follicles to be implanted.

The objective of the invention is to facilitate and ensure a correct design for the implantation of the hair follicles, ensuring a certain distribution and capillary density, for each one of the square centimeters, of the alopecic areas to be covered.

The device is made up of an electronic handle, where pressure and depth are controlled, and heads with a certain number of dermatological blades, which are attached to the head, whose purpose is to make incisions in the skin.

The invention is therefore situated in the field of aesthetic medicine.

BACKGROUND OF THE INVENTION

Hair transplant is a surgical technique of aesthetic medicine that in the last 25 years has had an enormous boom and has become today the most demanded aesthetic procedure by the male population since it is the most effective technique that exists to combat baldness or lack of hair density, women also benefit from it, although with less demand.

The most used technique today consists of extracting functional groups formed by one, two, three or more hairs at a time (which are known as follicular units or hair follicles), from a donor area, generally the lateral and back areas of the head, to later implant them in the areas affected by alopecia, commonly different areas between the frontal line (bang line) to the crown, but also beard or eyebrows.

Both the extraction and the sowing are carried out follicle by follicle. In short, the procedure consists of two different moments, that of the extraction of follicular units from the donor area and that of implantation in the recipient area. The most common technique for extracting each of the follicles consists of breaking the skin around the follicle using a manual or electric tool called "punch" and extracting the surgical piece by traction with forceps, something similar to hair removal with forceps. in this case of the complete follicle, it is normally called the FUE (Follicular Unit Extraction) extraction technique.

For implantation, it is possible to carry it out using three possible well-differentiated techniques:

• Making incisions and subsequent manual implantation with tweezers: Small incisions are made in the implantation area, each of the incisions will later serve as a place where the implantation or seeding of the follicles will be carried out one by one, which are placed manually. using a special clamp. The incisions are made with a special stylet made up of a handle and a dermatological lancet or blade, made of steel or another metal resistant to pressure during the incision and to chemical and physical sterilization, which is usually laminar in shape and ends in different types of tip and measure a few millimeters in width and height, and microns in thickness. Each incision must be made manually, creating as a whole a design that distributes the follicles throughout the implantation area, in addition to giving it a position or distribution, which implies a certain distance between the incisions themselves; also a direction, taking into account the naturalness of the "fall" of the patient's own hair and plane or inclination on the surface of the skin, and whose result is the naturalness, the adequate density and perfect coupling of the transplanted hair with which it can still remain on the surface where they are transplanted and with those around the alopecic area.

• Implanters; It consists of using instruments called implanters whose shape resembles a pen. The follicles must be loaded one by one into the implanters, which are nailed to the surface of the scalp, after which using manual pressure, they nail/implant the follicle in the skin. Some doctors previously make incisions with the previous method in order to reduce the pressure on the hair follicle by digging it into the skin.

• K.E.E.P. o waw implanter: It is a combination of the above instruments. It is a guide where the hair follicle is inserted, and by means of a clamp it is pushed towards an incision previously made in the skin, which collects it and where it is planted.

In any of the three, the closeness or distance in which the hair follicles are placed with each other determines the density that the patient will have for each square centimeter.

When performing both the incisions and the implantation of the follicles one by one, the possibility of obtaining a result of greater or lesser density remains in the manual skill of the implanter.

EXPLANATION OF THE INVENTION

The device for making incisions in hair transplant procedures that is recommended fully solves the aforementioned problems, allowing a perfectly homogeneous distribution of incisions on the skin surface to be filled, in addition to significantly reducing operating times.

For this, and more specifically, the device of the invention is embodied in an electronic device in which a handle-like casing, essentially cylindrical, and ergonomically shaped, adapts to the surgeon's hand, casing obtained in a resistant material that can be easily sterilized by chemical processes, removable to be able to clean the components that are susceptible to contamination by organic material during the transplant procedure.

An electric motor associated with a transmission is established within the casing through which an axis associated with a head is movable in an ascending and descending vertical direction, a head in which a series of blades are established strategically distributed dermatological on a plate, which will be stuck in the skin making an exact number of incisions in each of the impulses or movements of controlled descent of the head.

The electronics will be assisted by a power supply materialized in a rechargeable battery.

The device has a charging port, controls to control the actuation of the device, means to regulate the depth at which the incisions are made, as well as to regulate the thrust pressure of the head.

From the aforementioned head or with its corresponding plate, it is allowed to make an exact number of incisions in each square centimeter of the scalp where it is applied, all with the same depth and direction and plane on the surface of the skin.

DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of plans is attached as an integral part of said description. where, by way of illustration and not limitation, the following has been represented:

Figure 1.- Shows a front perspective view of a device for making incisions in hair transplant procedures carried out in accordance with the object of the present invention.

Figure 2.- Shows a plan view of the distribution of the blades provided on the plate that participates in the head of the device of the previous figure.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the device for making incisions in hair transplant procedures of the invention is constituted from a casing (1) in the form of a handle, essentially cylindrical, and ergonomically shaped, adapted at the surgeon's hand, about 15 cm long and about 2 centimeters in diameter.

The handle is made of a resistant material that can be easily sterilized by chemical processes, being removable in order to clean the components that are susceptible to contamination by organic material during the transplant procedure.

Inside the casing there is an electric motor associated with a transmission through which a rod (2) associated with a head (3) moves vertically up and down, in a controlled manner, to which a carrier plate for a plurality of dermatological blades (4).

More specifically, a potentiometer will participate in said transmission through which the pressure exerted on the stem (2) will be monitored, a pressure that can be regulated through the control interface (5) of the device.

The different electronic components involved in the device will be powered by a rechargeable battery through a network connection port (6).

For its part, provision has been made for the stem (2) to have a telescopic character, that is to say that it includes two sections that can be adjusted axially with respect to each other, in order to allow its length to be adjusted.

This length, adjustable, for example by means of a thread (7) that allows the end of one of the sections of the stem to be threaded to a greater or lesser extent in the other, together with the limit switches provided for the stem in the transmission associated with it. It allows to regulate the depth at which to make the incisions.

In this way, the thread (7) can have a dial with depth markings for example (0.4, 0.5, 0.6, 0.7, ... millimeters).

For its part, the head (3) may have a tilting character, through a ball joint or the like, in order to better adapt to the physiognomy of the head.

This head (3) will have means for coupling and uncoupling a plate carrying the blades (4), in order to allow the installation of plates with different distribution of blades.

From this structure, it is possible to make an exact number of incisions in each square centimeter of the scalp where it is applied, all with the same depth and direction and plane on the surface of the skin.

The plate will have a square shape, with a surface of 1 square centimeter, made up of a plastic or metal base oscillating with respect to the handle, where a certain number of dermatological blades are adjusted (for example 50/cm, 45/cm... ), which always allows the same number of incisions to be made in each of the impulses from the handle and towards the skin.

The blades (4), of dermatological incision (which are usually 1.2 mm wide), are separated at the same distance between neighboring blades, with a discontinuous parallel distribution, so it is ensured that the density will be the same. in all areas where it is used.

As an example, the plates with a density of 50 blades per cm are arranged with five rows of 10 blades, each one, with both rows and columns separated by 1 millimeter.

Plates can be designed with specific distributions, such as crown swirls.

It is possible to make the plates using hypodermic needles with the same criteria of density and separation between them.

The head, being tiltable, allows the surgeon's hand to decide the plane on the surface of the skin to which this set of incisions must be made, taking into account one of the criteria when making incisions (density, direction and plane on the skin). skin surface)

The plates associated with the head (3) are easily loaded and removed, so that in different areas where capillary implantation is to be carried out, a different number of incisions can be decided, based on the distribution and density criteria to be obtained. .

These plates are also disposable, ensuring the lack of surgical cross-contamination, and the poor performance of the incisions due to wear of the blades.

The result is a numerous group of incisions that, by areas, maintain the same depth and distance and ensure an exact density. Its use shortens the surgical time used to make incisions and enhances the success of the transplant by reducing the survival time in which the hair follicle is outside the skin.
