Hair transplanting device and method for the use thereof

Abstract

A direct hair transplanting device enabling sequential harvesting of single hair follicles from a donor region and implantation of the same at a recipient zone of the scalp comprising a tubular housing (30) with a forwardly projecting tubular needle (2) with an outermost end being formed with a conical obliquely cut knife edge cutting surface. A hair follicle is extracted through rotation of the cutting surface of the needle around a selected hair follicle at the target donor region of the scalp and implantation of the same at a selected recipient locus of the scalp being effected through initiating a forward stroke of a push rod (7) slidable within the interior of tubular needle (2) to implant the hair follicle into the scalp. Appropriate regulation and fine adjustment of the depth of intrusion of needle (2) into the scalp is obtained through differentiated depth of screwing of an internally threaded tubular shaft (35) holding the needle around an externally threaded perimeter of a cylindrical member (34) detachably mounted onto the tubular housing (30).

Description

THE FIELD OF THE ART[0001]The invention relates to the direct hair implantation and in this respect it discloses appropriate transplanting equipment enabling sequential harvesting of single hair follicles from a donor region and implantation of the same at a recipient zone of the scalp.THE BACKGROUND OF THE INVENTION[0002]Various hair implantation procedures and equipment associated with the implementation thereof have been employed in the prior art. Follicular unit hair transplantation is the procedure most commonly used. This procedure is however invasive since it involves removal of a strip of the scalp from a donor area and placement of the graft at a recipient area. Such strip removal necessitates shaving and leaves a scar that is difficult to heal, thereby posing restrictions in the client's normal activities over a rather long healing period. The process is rather slow with short daily sessions enabling implantation of a limited number of hair of the order of 500 units, whils...

AI Technical Summary

Benefits of technology

[0008]It is a further object of the invention to provide the aforementioned hair implanting device with means of appropriately regulating and fine adjustment of the depth of intrusion of the needle into the scalp to provide for optimum performance of the hair implanting device.

Problems solved by technology

This procedure is however invasive since it involves removal of a strip of the scalp from a donor area and placement of the graft at a recipient area.

Such strip removal necessitates shaving and leaves a scar that is difficult to heal, thereby posing restrictions in the client's normal activities over a rather long healing period.

The process is rather slow with short daily sessions enabling implantation of a limited number of hair of the order of 500 units, whilst its efficiency is rather low due to a large percentage of up to 20% of follicles being damaged during the removal of the strip and the subsequent division thereof in individual follicles to be implanted into the recipient zone.

Eventually since a number of sessions must take place to perform the overall hair transplantation process and since such sessions have to be scheduled with extensively long intervals in between, it becomes uncomfortably long to complete the process.

Furthermore, placement of hair follicles is subsequently performed by means of forceps thereby leaving much room for human error that often leads to oddly directioned hair at incorrect angles instead of the desired natural result of evenly angled hair.

Moreover such graft extraction and subsequent implanting process is not available for all clients, e.g. very curly hair cannot be extracted, and a preliminary test has to be conducted to determine whether the process is suitable for each particular candidate.
