Description

A NOVEL HAIR GRAFT IMPLANTER

FIELD OF THE INVENTION

BACKGROUND AND PRIOR ART

Hair transplantation technique involves transplanting live individual hair follicles from one part of the body which is usually called the "donor site" to bald or balding parts which is usually called "recipient site". Usually a strip is harvested from donor site first and donor site wound is closed by suturing the wound by surgeon. Another technique of taking out hair follicles is FUE [Follicular Unit Extraction] method in which a single hair follicle is taken out from donor area by coring it out with the help of a small punch and then with the help of a forceps it is extracted. The same procedure is repeated for extracting the required number of hair follicles. The important areas for hair growth are root [lower l/3^rd] and bulge area [middle l/3^rd] of the hair graft and the perfect level for implantation is when the epidermis of the hair graft and that of recipient skin exactly matches. The hair follicular unit may contain single or two or three or four hair. For implantation of hair graft surgeon has to make the slits or incisions or holes in the area desired and the hair grafts are implanted in the said slits or incisions or holes with the help of forceps. Hair graft implantation procedure is precise and delicate which needs repetition of the same step, resulting in a very lengthy and tedious procedure that fatigues the mind and hands of the surgeon and technician. Typically implantation is done with the help of implanting forceps which hold the hair graft from just above or below the root to implant it into the pre-formed incisions. Even trained technician and surgeon can also damage the important structures [lower 2/3 ] of follicle that is root and bulge areas, while implanting hair grafts and this damage affects growth of the transplanted hair follicles.

To overcome this damage, many surgeons are using implanters in which the graft is contained in a needle which pierces the recipient site skin and then the hair graft is pushed from the top of the graft into the skin. Many of these implanters use comparatively bigger size needle such as 16G or even bigger size which serve two functions [a] it punctures the recipient site skin to make a hole and [b] The hair graft which is carried in the lower end of the needle is pushed into the skin with the help of stiletto or a thin rod after puncturing the recipient skin. But implanting hair graft with big size needle causes more damage to the vital structure of the skin and also the distance between, two respective hair grafts remains more and so they fail to implant hair grafts with good density [such as > 40 hair grafts/ square cm] by such implanters.

Few of the implanters also use small size needle having insertion groove in its wall and through which a graft which is hold from hair shaft can be inserted in to the needle. In these implanters also the function of the needle is same and graft can be pushed from the top with the help of stiletto or a thin rod into the holes in recipient skin. Implanting hair grafts with the said implanters is easy and such implanters usually do not damage the important structures of hair grafts but such type of implanter implant the hair graft in straight track and chances of pop-out of such implanted hair graft increases upon the hair graft implantation in nearby area.

Additionally for piercing the recipient skin a force is required, so it becomes difficult to implant hair grafts with good density [such as > 40 hair grafts/square cm] by such implanters because previously implanted hair grafts in straight track might pop-out at the time of implanting subsequent nearby hair graft due to the force applied at the time of needle piercing the skin.

In order to prevent this pop-out, the new technique has been invented in which the needle is rotated at the time of piercing skin so as to create a curvilinear track into which the hair graft is implanted at the time of removing the needle and the hair graft is held in a better way than when the track is straight. But in these implanters, the surgeon has to rotate the implanter manually at the time of piercing the skin and the piston has to be pushed in co-ordination with retracting [body of implanter] with needle to prevent under or over insertion, making the use of these implanters cumbersome.

Further, in these type of implanter, after piercing the needle containing hair graft to be implanted in the skin, the said needle is retracted and the hair graft which is carried in the lower end of the needle is pushed into the skin with the help of stiletto Or a thin rod but while retraction the said needle retracts in straight track which makes the track straight losing the advantage of curvilinear track and increasing the chances of popping-out of the implanted hair graft. Moreover, while retracting the said needle a piston has to be pushed which causes the pressure and pops-out the hair grafts implanted in near by area.

Moreover, traditionally available hair graft implanter follows two step procedure for implanting hair graft (i) piercing the recipient skin by needle and (ii) pushing the piston to implant hair graft which exert the pressure causing pop-out of the implanted hair graft in near by area. Pushing the said piston and retracting the body of implanter need much more co-ordination and practice which leads to a bigger learning curve.

So as to overcome all above said problems, the present device is proposed which implants the hair graft with manual rotation in one direction while piercing the needle causing the curvilinear track for implantation of hair graft and which retract the said needle automatically with rotation in opposite direction of same degree without exerting pressure, significantly reducing the pop-out of the hair graft and shortening the process of implantation. The procedure is single step procedure which is easy to learn with significantly reduced learning curve. Further the proposed implanter is provided with needle having a predefined length remaining outside the implanter for implanting inside the skin with the desire length preventing under or over insertion, making the implanter user friendly.

PRIOR ART

Various types of hair graft implanter are found in the prior art but they have several disadvantages as compared to the proposed invention, each of which are described below: Many of these implanters use comparatively bigger size needle such as 16G or even bigger size which serve two functions [a] it punctures the recipient site skin to make a hole and [b] The hair graft which is carried in the lower end of the needle is pushed into the skin with the help of stiletto or a thin rod after puncturing the recipient skin. But implanting hair graft with big size needle results into the more distance between two respective hair grafts and thus it becomes difficult to implant hair grafts with good density [such as > 40 hair grafts/ square cm] by such implanters. Typically of these are US2003/0097144A1, US5439475 and US5578054.

Moreover, traditionally available hair graft implanter follows two step procedure for implanting hair graft (i) piercing the recipient skin by needle and (ii) pushing the piston to implant hair graft which exert the pressure causing pop-out of the implanted hair graft in near by area. Pushing the said piston and retracting the body of implanter need much more co-ordination and practice which leads to a bigger learning curve. Typically of these are US5578054, US2011/0046639 Al, US6461379B1, US2008/0009896A1 and WO2009/083741A1.

DISADVANTAGES OF PRIOR ART

The above mentioned inventions suffer from at least one of the following problems:

I. Many of the implanters use comparatively large size needles causing more damage to the vital structure of the skin. I. Most of the multiple graft implanters fail to provide hair graft implantation in curvilinear track in recipient site skin, resulting in more pop-out of the previously implanted surrounding hair grafts. III. Most of the implanters are not efficient as the chances of pop-out of previously implanted hair grafts are high, while subsequent nearby implantation due to the more force applied, especially while implanting hair grafts with good density [> 40 grafts /square centimeter].

IV. In many of the implanters the implanter is rotated manually when the needle is piercing skin so as to create a curvilinear track into which the hair graft is implanted at the time of removing the needle and the hair graft is held in a better way than when the track is straight but in these implanters, the needle is retracted in straight track which ultimately make the track straight losing the advantage of curvilinear track.

V. Further, in most of the implanters the piston has to be pushed in coordination with retracting needle to prevent under of over insertion, making the use of these implanters cumbersome.

VI. In none of the implanter the needle is retracted in curvilinear track which enhances the chances of popping-out of the implanted hair graft.

VII. In most of the implanter while retracting the said needle a piston has to be push to implant the hair graft causing the pressure and pops- out the hair grafts implanted in nearby area.

VIII. Majority of the implanters follows two step procedure for implanting hair graft (i) piercing the recipient skin by needle and (ii) pushing the piston to implant hair graft which exert the pressure causing pop-out of the implanted hair graft in nearby area. OBJECTS OF INVENTION

The main object of the invention is to provide a novel implanter which implants single hair graft in curvilinear track with significantly reduced pop-out of the nearby hair grafts.

Another object of the invention is to provide a novel implanter which facilitates the control over the rotational movement of the rotating needle while moving downward and upward.

Another object of the invention is to provide a novel implanter which implants the hair graft in a single step with significantly reduced pop- out rate and time.

Further object of the invention is to provide a novel implanter comprising of needles with thin wall and more inner diameter to accommodate larger size grafts without exerting crushing effect on graft.

Further object of the invention is to provide a novel implanter which implants hair grafts in a manner to facilitate the natural and pleasing appearance.

Further object of the invention is to provide a novel implanter which secures the graft to be implanted fully in lumen resulting in least extortion and damages at the time of implantation.

So to overcome all above said problems, the present device is proposed which implants single hair graft in a single stroke in which needle in the implanter rotates in one direction while piercing the skin to create curvilinear track and the needle rotates in opposite direction while retracting from skin over fixed stilettos making the implantation significantly easy and efficient and significantly reducing the pop-out of implanter hair grafts.
