Abstract

The invention relates to an instrument for taking and applying human follicular hair grafts, using disposable needles. The inventive apparatus provides a low-cost, simple, practical and effective solution to a tedious, awkward and very expensive problem to be managed worldwide. The invention can significantly improve human hair implantation while reducing the time, costs and personnel required. At present, numerous plugs of scalp have to be cut, divided individually into pieces with 1 or 3 follicles per graft and conveyed manually for implantation in the receptor bed. According to the invention, a single apparatus can be used to synthesise (reduce) the work of seven people to a single person, since the device not only cuts the hair-bearing grafts, but also prepares, divides and grips the grafts, as well as storing same individually or in groups of three in a row inside the needle. In addition to transporting the grafts, the needle preimplants the grafts in the receptor beds and reimplants same such that they can grow and fully develop. The inventive apparatus is hand operated, portable, light, dismantlable, versatile and can perform several functions simultaneously. The invention, which can be operated by a single person, comprises a handheld pneumatic mechanical apparatus having square- or round-tipped needles. Said apparatus facilitates the removal and application of human scalp grafts and the selective removal of follicular unit strips without damaging the follicles or the underlying plexus. Said modifications provide an improved operating performance and, consequently, the apparatus is more efficient, causes less follicular trauma and increases survival rates.

Instrument To implant hair.

Instrument To Transplant Hair.

Hair Implant Instrument. This author produces 3 very interesting designs. The first: It consists of taking several strips of scalp and cut them until you reach several uni or tri follicular grafts manually.

Then place the grafts on top of each other in a cartridge connected to an instrument to implant them in the donor area; By constantly feeding the cartridge with grafts, it uses the suction of air to pass the grafts from the cartridge to the injector.

The second: It also requires the previous manufacture of the grafts to constantly feed the cartridge and the injector.

That is, you have to load the gun and cartridge with hairs. The third patent is only to place and implant the grafts previously cut and loaded in the gun and the cartridge.

The difference of these patents with ours is obvious; Do not take them directly but you have to cut them one by one and load them as long as in our current patent under study. It is not necessary to make these previous cuts but this one performs them in a good way

U.S. PatentNo. 6059, 807 May 9/200

U.S. PatentNo. 5827, 297 Oct 1/1998

U.S. PatentNo. 5667, 661 Sep.2 / 1997

Author: Boudjema, These patents are quite interesting consist: The first one in:

A cylindrical instrument where a needle goes to carry only hair capillary (follicular) graft inside another needle. And inside the needle goes a cylinder that generates the vacuum when changing the graft inside the needle by 2 positions communicated by a small hole this procedure is only for one follicle compared with the present patent application under study; It is quite slow (one by one) tedious and only implants do not take them as in the current study.

The second patent of the same author; It is a needle that has inside a cylinder which rotates and rotates inside the needle and cuts at its distal end. Apply suction at its proximal end, to be able to extract said hair graft. This patent is the most similar to the present application under study. As for the mechanics; And idea of all studied.

It differs from the present study application in many parts and reasons.

First: Sola takes a small diameter graft. With the consequent slowness and boredom.

Second: We believe that the suction is insufficient to completely detach the follicle.

Third: We think it can damage the follicle.

Fourth: Lacks introducer; Injector or guide to enter it in the receiving area. Fifth: You work blindly since being the device so small it is difficult to guess the path of the follicles.

The third patent of the same author is quite useful to cut and take the grafts of donor areas since it cuts them into strips that are easily adapted later; But with respect to our present application under study. It does not implant them or transport them. Recent bibliographic reference: Barrera Alfonso, MD. Advances in Aesthetic Hair Restoration Aesth. Surg. Jour.2003; 23: 259 - 264 With regard to the patent PCT / MX 2003/000078 Dr. Navarro Ceballos this design is prior to the present development and basically, it differs in the tip of the bibiselado pusher in the inlet change of the suction and in the use of disposable needles.

CURRENT STATE OF THE TECHNIQUE The current state of the various techniques for transplanting human hair are reduced to taking a strip of scalp from the occipital area; Cut it in bevel in multiple mini-grafts of 1 to 3 follicles for each mini-graft and implant them manually in the donor area. They can not be placed or implanted beyond 2,000 to 2,500 self-grafts due to the fatigue factor; For which it is required 2 surgeons who take the graft (strip) and close the wound two others that cut into multiple fragments the strip of scalp.

Ottfos two who implant these fragments plus a circulating nurse plus the anesthetist: Minimum 8 people occupied during 8 hours of work to solve the problem in 2 or 3 sessions of 8 hours c / session. In contrast, this application under study only requires 2 people in the room; The surgeon and the assistant; Can be placed up to 300 grafts per session of 2.5 hours but with the use of 2 guns simultaneously could be placed up to 600 implants per session and solve the total problem in 4 or 5 more sessions, shorter time and lower cost.

Figure 8/13 longitudinal top view with lancets projecting out of the tip of the needle. Figure 9/13 shows the modified apparatus with the suction socket 17 and the connecting tube 18 installed in the handle and the hole 30 in the upper part where the outlet was formerly installed. Figure 10/13 shows the pavilion or head of the needle 9 with its slotted interior 10 for inserting the disposable needles and its mouth. Figure 11/13 shows the stem or body of the disposable needle 2 and its head.

Figure 12/13 shows how the folded sheet forms the body of the needle of the desired caliber its head this can also be a prefabricated tube. Figure 13/13 shows a needle with the pusher 25 whose tip is bi-beveled number 26 presents tip of the biblised pusher the number 1 is the tip of the disposable needle.

DESCRIPTION OF THE INVENTION Figure 1 shows the apparatus with the collapsible tail in a left side view has at the tip an interchangeable needle (2) of medical grade steel with the square tip sharpened and biblised (1) can be the thickest 14 gauge or 16 less thick in the first case, the light of the needle can capture 3 to 5 complete hair follicles. In case 2 ^or can be captured from 1 to 3 hairs with their follicles. On each side of the needles are attached two lancets or T-shirts (4) joined at the top by a secondary trolley (3) that slides these t-shirts outside the tip of the needles and join 1 cm. outside or beyond the tip of the needle. When this is introduced to the scalp and helps to detach the bite of its insertion or internal base without damaging the hair follicles it is decided that they act as very fine forceps that take or capture the bite; These t-shirts are separated when they are out of the tissues by the needle and join within the cranial tissue. They are made of very resistant tempered medical grade steel with sharp tips and claws (see figure 8) inter combined at both ends. The secondary cart system (3) is a cart of approximately 0.5 m. x 1 cm with

4 holes In the upper one, the pusher wire (14) of the secondary trolley (3) is welded to the middle one, the needle (2) goes through it and the rods (5) that hold both t-shirts (4) are attached to the pavilion. the needle (9) is fastened; Fixed and connected to the main body of the appliance by means of the metal bracket (9 ") (see figure 2 and 4) that joins the tip of the body (7 ^r ) with the needle (2) by means of a screw (9") (see figure 3) the body of the device measures approximately 2 cm. of diameter x 14 cm. long has 5 main parts: Antecuerpo (8) that measures approximately 2 cm. of diameter x 5 cm. long approximately. Body (7) handle (23) tail (20) and tip (inside the pavilion of the needle). The whole body is hollow to have a vacuum chamber (29) see. (Figures 5 and 6) and also between the body and the forebody can be divided into 2 parts by a thread that has a seal "o" ring (24) to find the vacuum in the chamber and for cleaning and maintenance purposes. The antecuerpo has a hollow metal handle (23) attached to its side for two purposes. First for better grip; Prehension and maneuverability.

Second so that in the future it can be added inside; Cables; Tubes-Micro chips and switches. Always on the right side face of the forefoot there is a groove (11) where the primary carriage (12) has a quadrangular shape with 2 perforations 1 along its body to slide the pusher wire (14) of the cart 2 ^or being imprisoned by the screw (13) that at the same time that fixes the primary trolley and the wire serves as pusher button of the secondary pot (3) said lateral side of the forefoot has a U-shaped sheet (16) in the lower third of the distal end of the fixed body to said end by means of 2 screws (15) and whose main mission is to prevent the primary trolley from leaving its channel serving as a stop. Always in the same figure 1 on its right side inside the handle, there is another element in the form of a tube (17) having two ends because its base is screwed to the forebody and communicates with the empty chamber of the body (30) (see figure 5). and 6) and on the other (18) is connected to the hose or suction tube and on the opposite side a hole (30) is plugged by the thumb of the operator to increase the vacuum in the chamber. When the appliance is in operation.

Always in Figure 1 the tail of the device (20) (see Figure 6) measuring 3.5 cm is observed. approximately 1 cm long of approximately diameter and having a tube measuring approximately 4 cm attached as a cap (21) or telescopic tubular T-shirt. long x 1 cm in diameter; Hollow inside with a longitudinal channel on its left side that measures about a window of approximately 3.5 cm. long x 4 mm. Wide. It has at its distal end of the tail and the window a screw (6) that serves as a stop to the cap so that it does not leave the tail when it is telescoped. The function of this cap is to bring the main pusher (25), which longitudinally crosses the entire apparatus in the center as a main axis, to its roof or upper extremity. Said axis is a wire of a size somewhat smaller than 16 or 1.4 respectively, it has at its distal end welded the telescopic cap (21) and at its anterior or inferior end a bevelled expanded tip (26) (see figures 5 and 6) that prevents the graft taken by the needle is locked between the light of the needle and the pusher and on the other hand that allows the passage of air in both directions and finally that can slip inside the light of the needle without locking and also prevent the grafts from passing into the chamber empty. (That is, it also serves as a buffer). With respect to figure 2 this is a right side view of the apparatus with the telescope cap on the tail where no new elements appear, the rest of the components have already been widely described in the previous figure.

With respect to figure 3, this view is a view of the left side where there are no new visible elements except for the needle connector bar (9 ") with the forearm.

With respect to figure 4 this is a top view.

Where there are no new elements but it gives a new perspective of the previously described elements in general. With respect to figure 5 this is a longitudinal cross section to try to capture the internal mechanism and its movement that has been neatly described in figure 1 paragraph 20 to 30. It also carries the communication (30) with the hollow ante-body with the body . The numbers 27 and 28 show the "o" ring to keep the vacuum (29). With respect to Figure 6 this is another cross section of the apparatus with the telescoping cap and the tip of the pusher (26) retracted towards the pin pavilion (9) and the communication (30) with the antecuerpo and internal hollow chamber.

Figure 7 shows a 16 gauge needle but can be 14; But with the square tip and bi-bevelled with cutting edge for the punch, and several snacks in its interior (31).

With respect to Figure 8 this shows all the characteristics described above is only put to illustrate the mode of action of the lanzetas or side capture shirts (4). With respect to Figure 9 shows the modifications to the previous apparatus

PCT / MX 2003/000078 consisting of the following:

(30) hole where the three-way valve was and remains as a digital shutter.

(17) Interconnector tube with handle for suction. (4) Sliding lateral lancets.

(18) Suction connector.

With respect to figure 10 the (9) shows the flag of the needle and the

(10) shows the thread of the disposable needles.

With respect to Figure 11 shows the square tip disposable needle With respect to Figure 12 shows the needle made with cutting blade. With respect to Figure 13 shows the mechanism of action of the pusher wire whose bibiselada tip (26) is retracted to be inside the needle but lets air pass and expands to exit pushing the graft preventing it from locking. The mechanism and function of the appliance whose application is present; It consists of the following; Since the current state of the art worldwide consists of cutting strips of scalp.

Either with scalpel or laser from the back of the head; Close the wound and cut the grafts in multiple fragments and reingraft them again in the frontal receptor areas; Through magnifiers and very fine instruments; Our application in study takes; Section - cut - transport - place and insert said grafts in place by a single equipment; By a single person; Without damaging the follicles or the donor area. As follows: Under local and regional anesthesia of the patient. This anesthesia of the areas to be treated lasts approximately 214 hours. The tip of the needle of the device is inserted into the donor areas of the nape with an angle of 45 ° with respect to the head, trying to follow the path of the hair follicles. The needle, as it is sharp, is inserted into the scalp up to 1 cm. without reaching the bone because previously this area was dilated (swollen) up to 3 cm, by the use of Subcutaneous anesthetic liquid. The needle is not inserted beyond 1 cm. because the side t-shirts (4) serve as a stop in their union with the cart 2 ^or (3) even though the hair grafts remain inside the light of the caliber of the needle; But these hairs and follicles inside the light of the needle are cut off; Sectioned but still attached to its bed therefore, if at this time the needle were removed the hairs would not leave the receiving bed because they are still connected, but if they would come out of the needle. Unless we applied a force of attraction to the needle by suction; Even so, the suction is not enough to detach them, so the side t-shirts come into action (4) that, when moving beyond the tip of the needle inside the cephalic tissue, practically remove the hair follicles from their base intact and complete. As if they were micro clips. This would be equivalent to an injection for which there is no trace in the donor area, and does not require stitches or require the patient to take analgesics later.

The graft captured by the punch of the needle is captured in the intraguja lumen; It is carried or transported to the frontal receptor areas and by means of a previous incision with the No. li scalpel or the same instrument practices a punch or perforation in each of the receptor areas. This incision is extended to the deep tissues following the - Yes -

route of the hair follicles through the guides that are the t-shirts that are introduced below the front skin plus or minus 1 cm. opening space for sowing the grafts in a suitable place. When removing the side shirts; It comes almost simultaneously the tip of the pusher (26) carrying the grafts to deposit in their new bed this can be done every 5 millimeters a graft of another. And in another session. Since the grafts are well integrated; Fill or fill more distances up to 4 and 5 millimeters apart between each graft. The square tip of the needles takes square grafts which allows that in the normal healing process the grafts are not constricted or asphyxiated since it is well known that the cicatricial contracture when it is round; Squeezes and hangs the implanted neo implants avoiding this problem for square punching with hair follicular grafts. The process can be done with 2 pistols maybe three, and the antecuerpo "head" can carry a double mechanism of 2 or more needles to further streamline the process.

In short, the apparatus whose current request is in the present study; It not only simplifies a whole process but saves personnel; Weather; Costs and less discomfort for patients with satisfactory results in the growth and development of transplanted hair follicles. In addition to not hurt the donor bed.

MODIFICATIONS TO THE PREVIOUS TECHNIQUE

Instrument for the taking and application of human follicular hair grafts with disposable needles. Object of the invention.

To make more optimized the handling of the current instrument as opposed to the previous one by means of the upper positional change of the suction inlet that obstructs the visualization to lower inside the hollow handle can be placed in addition to the suction tube; microchips; cables; etc. Keeping the upper hole for handling as an obturator of the increase and discharge of negative pressure with the thumb and making the cutting of the scalp more efficient by changing the thickness of the needles for thinner and sharper blade while being disposable they adapt better to universal health requirements. With respect to the previous international patent PCT / MX 2003/000078 and dealing with a new manual pneumatic mechanical instrument for the taking and implantation of human scalp grafts; and with respect to the current state of the art this version is more sophisticated since with respect to the previous one it can selectively take follicular units and the needles are disposable and of thinner thickness of less than 1 mm. of thickness to make the intake and application less traumatic and functional, as well as to adapt to international sanitary regulations, another modification has been to place the suction inlet at the base of the gun for better visibility; practicality and optimization in its execution; retaining the top insertion hole ¹ to generate and decrease the deposit. From the inner chamber. With any finger of the operating hand.

The best known method for carrying out the invention in view of figures from 9 to 13. It is noted that in figure 9; the upper entrance path (30) has been changed to a lower one; (17) by means of an interconnected tube (17), speeding up and optimizing the operation and vision; likewise in figures 10, 11, 12 and 13 it is observed that in the pinna of the needles (9) an internal thread (10) has been adapted to facilitate the replacement of the needles for better cutting with less trauma and of disposable type since these tubular soη with thickness less than 1 mm. For a more sharp and less traumatic cut. DETAILED DESCRIPTION
