Definitions

  • the present invention relates to a planting device to plant plantable material in diverse substrates.
  • the invention further relates to a hair plantation device capable of speedy, accurate and atraumatic plantation of hair follicle while maintaining follicular integrity resulting in better yield, and method of its use in hair restoration process.
  • the present invention generally relates to devices for hair follicle transplantation.
  • a variety of restorative approaches have been used to deal with problems of baldness due to hair loss by processes such as using hair pieces, topical application, oral medication, scalp reduction, scalp flaps and hair transplantation.
  • the goal continues to be to provide affordable long lasting or permanent solutions without side effect for natural looks with / without minimal maintenance.
  • Follicular hair transplantation is now widely accepted as the best restorative procedure as it fulfills most of the above criteria.
  • Clinical study has revealed that when longer lasting hair from back and side of scalp are transplanted over the area of baldness, hair continues to stay viable and grow.
  • Hair transplantation procedure comprises three steps wherein the first step involves the harvesting of hair roots from the permanent zone, the second step involving their separation and the third step in which the individual roots are planted in the desired area.
  • the plantation process generally involves steps that include creation of an ideal recipient site, keeping the site open and placement of the graft into the site maintaining its integrity and stability.
  • Blades number 11 , 15
  • trokars of different shape (triangular, mercedes, rectangular) and needles are used to create slits in the skin.
  • multiple slits are created by one person as a first step followed by simultaneous placement of grafts is done by several persons.
  • a slit is created by one person followed by placement of graft in the created site as a second step by the same person.
  • grafts are picked and held by forceps or similar grasping instruments and pushed into the recipient slit or hole.
  • Such methods suffer from problems of drying of tissues, mechanical damage to the vital cells during holding, grabbing, pinching, dragging and pushing. Insertion of the graft by such techniques also have problems of crushing, squeezing, folding, distorting, jamming, distracting and bending of hair grafts.
  • the separate step of "slits creation” is an additional step and at the same time increases the burden of counting and isolating grafts to match the number, size including width and depth of the slits. It is possible to miss sites, piggy backing (more than one graft in one cavity), hair under graft, slipping too deep and rough placing with multiple attempts. These consume additional time of the surgeon and impact the cost of the surgery.
  • a transplanter device is first loaded with graft arid the loaded transplanter is used to create the site and immediately place the graft in the created site in one single motion by one person.
  • the PCT Publication 2001/010307 provides a planter wherein the process involves the insertion of a needle into a scalp having a pointed end portion to reduce damage of the scalp, and a guide plate which is adhered to an end portion of a sliding unit reciprocating in the longitudinal direction of the needle outside the needle, prevents hair roots from being separated at the time of the separation of the needle.
  • the hair roots inserted into a needle insertion groove are not damaged and are naturally settled in the scalp without modification, thereby stably performing the hair transplantation.
  • this instrument and method is a significant improvement over the earlier instruments and methods, it has several disadvantages.
  • the instrument construction performs a "blind plantation", needing to align the follicle, adjust the depth control every time the length of follicle changes and is severely limited to the use of stiff hair that is preferably 6 mm long and is not good for untrimmed harvested hair.
  • Folding, bending, twisting arid squashing of follicles are not visible / identified and even if identified, it is difficult to take corrective action.
  • the short beveled cannot create the desired spiral cavity on the scalp and also the follicle needs to be pushed with force causing faster blunting of the sharp end thereby requiring frequent changing of the needle resulting in longer time for completion of the procedure.
  • WO 2003/096906 A2 was a major improvement over the prior art in which the transplantation device has a longitudinal groove having a wider slot as a loading area and a narrower slot as a retaining area further developing into a tapered sharpened wedge with depth control performing desired multiple functions of a dissector, site creator, stopper, spiral cavity maker, stretcher, separator and slider capable of harvesting and planting.
  • the device functions without electricity, suction or spring assistance having the advantages of being multifunctional, small, light weight, handy, autoclavable, sterilisable, disposable, having minimum joints and moving parts yet easily manufactured in wide range of sizes from various materials, with capability to harvest and plant wide range of plantable materials into diverse substrates at enhanced plantation speeds maintaining follicular integrity resulting in better yield.
  • the device of this invention has an optional holder and a handle and is functionally cost effective with easy learning curve and versatile acceptability.
  • This device though a distinct improvement over the prior art, is also not free from disadvantages.
  • this device requires two hands to conduct the procedure. As the two hands occupy most of the plantation area (recipient site) only one person can conduct the procedure thereby reducing speed of the plantation process and the plantation is possible only by standing behind the patient. Conducting the procedure by standing on front and side of the patient is not possible.
  • the learning curve is slow for professionals with less surgical experience. The number of assistants required is high leading to a higher cost of the entire procedure.
  • WO 2013/015534 discloses a hair transplant device for transplanting hair onto a region of thinning hair.
  • the hair transplant device is very useful in that during a hair implant operation the device can precisely adjust and set the length of an implanting needle in which a hair root is inserted and the depth of a spindle according to a thick layer of skin tissue found in the scalp of each person, thereby improving hair graft rates and hair transplant results.

  • the present invention provides advantages of remarkably reducing the assembling time for operation, making the assembling method more convenient and simple, and allowing easy use by an operator. Furthermore, the present invention has advantages of allowing an operator to find a slit direction easily, and providing easy maintenance because the fixing cap prevents a hair transplanting device from rolling around when an operator puts the hair transplanting device on an operating table.

Abstract

La présente invention concerne un dispositif d'implantation pour implanter un matériau implantable dans divers substrats. En particulier, l'invention concerne un dispositif d'implantation capillaire capable d'implantation rapide, précise et atraumatique de follicule pileux tout en maintenant une intégrité folliculaire conduisant à un meilleur rendement et un procédé de son utilisation dans un processus de restauration capillaire. La combinaison synergique desdits boîtier, ensemble de piston à ressort, ensemble de cylindre du présent dispositif d'implantation évite la nécessité d'un mélange de contrôle de profondeur dédié et évite le greffage en aveugle du matériau implantable tel que des follicules capillaires dans le substrat étant donné que le piston du présent dispositif contribue au positionnement approprié et contrôle l'implantation du follicule pileux avec une précision souhaitée sous l'observation de l'utilisateur. Cela permet en outre des fonctions multiples de dissecteur, créateur de site, arrêt, dispositif de fabrication de cavité spiralée, extenseur, séparateur et curseur maintenant l'intégrité du matériau implantable pendant l'implantation.
