    Tools and methods of use for an automated forceps expansion system for graft implantation in the premade skin incision. The automated system for graft implantation, has a tubular body, with a forceps mounted on top of the tubular body. The forceps is operatively associated to a spring, controlling the movement of forceps arms. The spring is coupled to a plunger. The plunger is disposed axially within the tubular body. The plunger on the distal end of the tubular body is operatively associated with a tube. The tube is used to pass pneumatic pressure to the plunger. This pneumatic pressure is created by a compressor unit attached to the tube. The pneumatic pressure once created, releases air in the tube. The tube attached to plunger moves the plunger axially forward causing compression of the spring and thus a positive pneumatic pressure creation causes the forceps to open. When the pneumatic pressure is stopped, the spring causes, negative pneumatic pressure and starts decompressing, this results in the forceps to return to the original closed state.

    AUTOMATED FORCEPS EXPANSION SYSTEM
    DESCRIPTION
    FIELD OF THE INVENTION
    The present invention relates, in general, to a tool used for therapeutic medical procedures and, more particularly, it relates to a tool used for implantation of hair grafts.
    BACKGROUND OF THE INVENTION
    Hair transplant procedures are well known, and typically involve (in a patient who has male pattern baldness) the collection of donor hair grafts from areas of the lateral and posterior fringe (donor areas) of the patient's scalp and implantation in baldness areas (receiving area).
    Hair restoration doctors who perform follicle implantation depend heavily on their own experience and preferred implantation tools to carefully implant follicles.
    Typically, forceps are used to grab and place the grafts of the follicular unit in previously made indentations, although other instruments and methods for performing it are known.
    Certain instruments available, for example, automatic implants, do not dilate the grooves efficiently and, therefore, dense packing of the grafts with automatic implantation systems is not possible. Also, the manual use of forceps has certain limitations.
    (a) Limited resistance of the forceps to dilate the cleft of the previously performed skin.
    (b) A user has to control the forceps with his hand. The user may be comfortable maintaining pressure and grabbing the forceps to control the forceps using his dominant hand, but has difficulty holding the forceps in the non-dominant hand.

    Constant pressure and continuous use of the non-dominant finger causes fatigue in the fingers.
    Automated forceps expansion is a novel invention that reduces the learning curve between beginners and, at the same time, provides an efficient grip on a non-dominant hand. It also reduces the chances of fatigue in human hands and increases the speed of this surgical procedure along with a higher level of accuracy. The process involving said invention produces minimal graft trauma.
    Other objects and additional advantages of the invention will be clearer from the following detailed description when read in view of the attached figures.
    DESCRIPTION OF THE INVENTION
    The objective of the present invention is to provide a novel system of implantation instruments.
    An embodiment of the present invention is a graft implant system comprising: a tubular body; a forceps mounted on the proximal end of the tubular body; a spring arranged longitudinally within said tubular body and operatively associated with the forceps; an axially arranged plunger between the proximal and distal end of the tubular body and coupled to the spring; a tube at the distal end of the tubular body, coupled to a compressor with a pneumatic valve unit, operatively associated with the plunger.
    An embodiment of the invention also presents a system for controlling a pneumatic pressure inlet in the system for implanting grafts through the tube and a compressor unit.
    In one of the embodiments of the invention, the plunger moves axially when a pneumatic pressure is applied. This displacement is an axial forward movement.
    In one of the embodiments of the invention, when there is no pneumatic pressure, the spring is decompressed by guiding the axial movement back of the plunger.
    In a preferred embodiment of the present invention, the forward movement of the plunger changes the state of the spring so that the compression of the spring diverges or opens the arms of the forceps.
    In a preferred embodiment of the present invention, the backward movement of the plunger changes the state of the spring so that the decompression of the spring converges the arms of the forceps. The backward movement of the piston is the result of the force of the spring acting on the piston in the absence of pneumatic force.

    The adjective "automated" with reference to a system or process as a whole means that a part or all of a particular system or stage in the process implies an autonomous mechanism or function; that is, that mechanism or function does not require manual action. Ultimately, one or more stages in the procedure can be automatic, or autonomous, and some parts require manual entry. This definition encompasses an automated system that requires only one operator to press an activation switch or program the operation, and also a system in which hand tools are used, but some mechanism of the system works autonomously, that is, without human intervention. , to perform a function. Some of the automated systems described here can also be robotically assisted or controlled by instructions from a computer / software / machine. The devices and methods of the present invention are useful in manual procedures and systems, as well as in automated procedures and systems. The tools of the present invention could be used with robotic assisted procedures and systems. The adverb "automatically", when referring to the use of a particular component of a system or a particular stage in a process, means that said stage is performed autonomously, that is, without real-time manual assistance. The terms "coupled" or "attached", or "connected" or "mounted" as used herein, may mean coupled, attached, integrated, or mounted directly or indirectly through one or more intermediate components.
    In one of the embodiments of the invention, an automated system for implanting grafts is provided. This comprises a tubular body 203, see Figure 2. The tubular body acts as a housing chamber that encloses, in different embodiments, mounting parts of the present invention.
    In Figure 1 reference is made to an embodiment of the invention. It refers to a two-arm forceps 101 mounted on the tubular body. The aforementioned end of the tubular body that supports the forceps 101 is known as the proximal end of the system. The forceps is coupled, connected to the spring 102. The spring 102 is positioned or arranged in the present invention longitudinally. The operation or functionality of the spring affects the elastic movement, in which the compression of the spring causes the arms of the forceps to reach an open or divergent position. And the decompression of the spring causes the forceps to converge or be arranged in a closed form.

    In a preferred embodiment of the invention, the tubular body houses a plunger 103. The plunger is arranged axially within the tubular body so that its position is between the proximal or distal end of the tubular body. The plunger is coupled to the spring towards the proximal end of the tubular body.
    In one embodiment of the present invention, a tube structure 204 is present at the other end of the tubular body. This end is known as the distal end of the tubular body or the system. The tube 204 is attached at the distal end of the tubular body and the other end of the tube 303 is connected to a compressor unit. In another embodiment of the invention, the compressor unit is responsible for generating pneumatic pressure.
    In an exemplary embodiment of the invention, with reference to Figure 2; The compressor unit generates a pneumatic pressure force, when the user presses a unit or pedal switch. This creates a pneumatic pressure as is known to those skilled in the art, thereby releasing air into the tube 204. The air pressure thus causes the piston 103 to slide, to move the pneumatic valve axially forward and the pressure regulator. regulates the exact amount of pressure.
    In an exemplary embodiment of the invention, since the piston is coupled, attached to the spring, the forward axial movement of the piston causes the spring to compress. The compression spring causes the opening or divergence of the arm of the forceps. That is, the arm of the forceps is separated, see Figure 2, 201.
    When the compressor generates the pneumatic pressure and releases air in the tube to move the plunger forward towards the proximal end of the tubular body, it is known as positive pneumatic pressure.
    When the compressor stops creating or generating pneumatic pressure, the spring changes its state and begins to decompress. Decompression of the spring results in convergence of the forceps arm and closure of the forceps arm occurs, see Figure 4 of the system of the present invention. The decompression of the spring also pushes the piston back, thus guiding the axial movement backwards of the piston. This effect is known as negative pneumatic pressure. The closed state or position of the forceps arms is the original position of the original state or position and is obtained with a zero error using the mechanism described.
    In the present invention, the following steps are repeated as operational stages of the analyzed automatic system:
    5 • The user holds the device in his non-dominant hand.
    • Next, the user places the terminal end of the forceps in the previously made skin incision.
    • Pressing the foot switch releases air inside the rubber tube and creates a positive pneumatic pressure.
    10 • The positive pneumatic pressure pushes the plunger creating an axial forward movement of the plunger and forceps.
    • Forward movement of the forceps releases the arms of the subject forceps strongly and thus an expansion occurs at its proximal end.
    • When the foot switch is released, pressure is released allowing the forceps 15 to retain its resting position because the backward movement of the spring pushes the
    piston in a backward direction.
    The embodiment of the present invention can also be understood as the following steps:
    twenty
    • A specially designed forceps fit inside a plunger tube. The distal end of the tube connected to another small rubber tube that finally connects to the compressor.
    • Positive pneumatic pressure created through the travel of the compressor through the rubber tube 25 coupled to the distal end of the device driving the plunger.
    • A forward movement of the plunger further pushes the forceps to move forward and expand its two arms.
    • It also pushes the spring forward.
    • When pneumatic pressure is released, the spring action backwards pushes the piston 30 backwards allowing the forceps to maintain its resting or closing position.
    Referring again to Figs. 1 and 2, in a particular embodiment, the length of the forceps 101 is approximately 3.5 cm. The length of the tubular body 203 is approximately 10.5 cm. The opening of the arm of the forceps 201 is between 2.5 and 4 mm.
    However, still in other embodiments, the main tubular body 203 can be of any dimension, wider, narrower, thinner, thicker, or shorter.
    In one embodiment of the present invention, the end plate 205 is the plate that forms the base and holds the forceps coupled to the spring 7.
    In a preferred embodiment of the present invention, the plunger 103 may comprise, for example, a device in which a mechanical, hydraulic, pneumatic or electromotive force acts on the plunger 103 to cause an axial forward movement.
