DEVICE FOR PLACING FOLLICULAR UNITS

Description

1 / 6 Descriptive report for the utility model patent: Device for placing follicular units. FIELD OF THE INVENTION

[001] This document pertains to the field of medicine, more specifically to the field of plastic surgery directed at patients with baldness. It concerns a device for the placement of multiple-shot follicular units. DESCRIPTION OF THE STATE OF THE ART

[002] Baldness is a common problem affecting millions of people worldwide, and hair transplantation is the only definitive solution for treating the condition. The development of the Follicular Unit Excision Procedure (FUE) technique has allowed for significant progress in results, but innovations are needed to ensure the preservation of follicular units, especially regarding their placement. There are various implanter options on the market, but they are still imported, expensive, and require a large team for replacement.

[003] The present invention presents a manual device for placing multiple-shot follicular units, which integrates a set of technological innovations, such as easy handling and hygiene.

SUMMARY OF THE INVENTION

[012] The present invention is used in hair transplantation using the FUE technique, is manual, and comprises a tip (1), a Petition 870210111975, dated 02 / 12 / 2021, page 8 / 17 4 / 6 head (2) with orifices, a regulator (3), up to 3 individual side trigger buttons (4) for each needle, where each needle has a spring (5) involved to allow firing, at least one needle insertion depth adjustment button located on the top of the device, up to 3 needle firing buttons and the device loads up to 3 follicular units simultaneously. OBJECTIVES OF THE INVENTION

[013] The present invention aims to present a model of an implanter device for placing follicular units. The invention assists in placing follicular units, removed by the FUE hair transplant technique, in the scalp in a way that reduces manipulation of the hair follicle bulb region and reduces the number of device changes between the surgeon's hand and the surgical assistants, increasing the efficiency of the procedure and reducing surgical time. Furthermore, with the described device, fewer implanters are needed per surgery, and the device's shape facilitates cleaning and sterilization. The device of the invention also features an ergonomic shape for the implanter, even though it has multiple loaded needles. BRIEF DESCRIPTION OF THE FIGURES

[017] The present invention relates to a device for placing follicular units comprising: - A tip (1) where the needle containing the follicular units (FU) is externalized; - A head (2) with holes that facilitate cleaning of the device and that serve for the insertion of the actuator buttons; - A regulator (3), responsible for determining the depth of needle penetration with the graft; - A trigger (4), responsible for the individual activation of the needle; and - Spring (5), which surrounds each needle to allow firing.

[018] This manual device has the ability to load up to 3 follicular units at a time, with individual firing by piston action of the needle loaded with graft, using an individual side button for each needle. The needles used are surrounded by internal springs (5) that enclose each needle, and which are activated by the side buttons. The needles in the device can be disposable, made of stainless steel, with a cutting bevel, as can the springs (5) and the piston. The implanter body is Petition 870210111975, dated 02 / 12 / 2021, page 10 / 17 6 / 6 anodized aluminum or durable, autoclavable plastic material.

[019] The development of the 3-needle device was carried out with the aim of reducing the chances of graft drying out due to exposure to the environment.

[020] The aforementioned invention assists in placing follicular units, removed by the FUE hair transplant technique, into the scalp in order to reduce manipulation of the hair follicle bulb region and reduce surgery time.

[021] The said invention has an ergonomically favorable shape, despite having multiple loaded needles. The needles can be replaced, which makes it possible to change them during surgery. Petition 870210111975, dated 02 / 12 / 2021, page 11 / 17
