Hereinafter, a needle unit according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an example of a conventional elastomeric tandem needle unit applicable to a hair implantation device. 2 and 3 are examples of the parallel arrangement of the needle unit of the elastic body according to an embodiment of the present invention applicable to the hair transplantation device.

The conventional needle unit as shown in FIG. 1 and the needle unit according to the present invention as shown in FIG. 3 are different from each other in the housing structure and the arrangement of the elastic bodies. Any can be used as a needle for implanting hair follicles into skin tissue by mounting it on various hair transplantation devices, including the hair transplantation device described below.

Needle unit 100 according to the present invention is configured to be used in the hair transplant apparatus 200, the hair transplant apparatus may be a conventional automatic or semi-automatic hair transplant apparatus used in the art. The needle unit according to the present invention can be used without limitation in form if it is manufactured in accordance with the standard of the hair transplantation device and the structure of the driving unit.

Needle unit 100 according to an embodiment of the present invention, as shown in Figure 3, the needle 110 is protruded to face outward. The needle 110 may protrude further in an external straight direction when the inner housing 130 is pressed and interlock at an end of the inner housing 130.

The needle 110 is configured to protrude to a suitable length to reach the target implantation point for implanting the hair follicle 200 into the skin. If too long, flow between the shaft operations of the core where straightness is important is amplified, which is disadvantageous for transplanting hair follicles precisely at the target point, and too short may cause interference by surrounding hair, which may be disadvantageous for accurately transplanting hair follicles at the follicle transplant site have. The maximum protruding length of the needle 110 may be manufactured to an appropriate length in consideration of the entire length of the needle unit 100.

Needle unit 100 according to the present invention constitutes an outer housing 120 to be a body, the inner housing (120) to allow the linear movement along the space provided in the outer housing 120 with an external force inside the outer housing (120) 130 is installed, and installs the core along the inner housing (130). The core part is divided into the head bundle 140 and the shaft 150 aligned with the needle 110 and installed in a direction parallel to the longitudinal direction of the inner housing 130.

Then, the first elastic body 160 for holding the inner housing 130 in the outer housing 120 is installed, and the second elastic body 170 for holding the head bundle 140 and the shaft 150 in the inner housing 130. Is configured by installing The first and second

elastic bodies

160 and 170 installed in this way are assembled in a parallel arrangement in which the first elastic body 160 is surrounded by the second elastic body 170.

Hereinafter, the configuration of the needle unit according to the present invention will be described in detail.

The housing unit may further include

housing caps

121 and 131 coupled to one end of the outer housing 120 and the inner housing 130.

One end of the inner housing 130 may be installed in a structure in which the needle 110 is protruded to be interlocked by the inner housing 130. Needle 110 is a guide hole 111 for receiving the hair follicle 300 is formed at the same time to guide the movement of the shaft 140.

Here, the needle 110 is formed of a protruding shape protruding from the outer housing 120 and the inner housing 130 and the end is formed in a pointed needle shape to facilitate penetration into the skin tissue and the hair follicle 300 skin It is desirable to fabricate shapes that are suitable for implantation into tissue. The figure shows an example in which the inclined cross section is placed on its own to have a pointed tip.

The outer housing 120 and the inner housing 130 have

spring receiving spaces

122 and 132, respectively. In the spring receiving space 122 of the outer housing 120 is mounted by mounting the first elastic body 160 along the longitudinal direction. In the spring receiving space 132 of the inner housing 130 is mounted by mounting the second elastic body 170 in the longitudinal direction.

Thus, the first and second

elastic bodies

160 and 170 respectively installed in the outer housing 120 and the inner housing 130 may be mounted in a superimposed parallel arrangement form rather than in parallel arrangement in parallel with the core portion. have.

One end of the inner housing 130 has a ridge plate 133 that is elastically received by the first elastic body 160 according to a moving direction of the core portion. The ridge plate 133 holds the first elastic body 160 mounted in the spring receiving space 122 of the outer housing 120 so that the inner housing 130 moves along the inner housing 120 by external force. When the elastic body 160 moves while compressing, and the external force acting on the inner housing 120 is reduced or eliminated, the spring elasticity acts on the ridge plate 133 to return the inner housing 120 to its original position.

The core unit is divided into a head bundle 140 and a shaft 150, and the head bundle 140 and the shaft 150 constituting the core portion may be configured as a separate type or as an integral type.

The detachable type may be configured to assemble the head bundle 140 and the shaft 150 by a male and female screw coupling. In this case, if there is damage or breakage of the shaft 150 or the head bundle 140, there is an advantage that only the corresponding parts can be used.

The integral type is impossible to partially replace the shaft 150 and the head bundle 140, but there is an advantage in processing and assembly.

In either case, these advantages are those that can be expected by constructing a portion of the shaft 150 as a head bundle 140.

The ball bundle 141 puts a ball (141). The head bundle 140 including the ball 141 allows movable rods such as movable pins or rods to transmit external force to enter the ball 141 to transmit the pressing force.

Ball 141 is a stable linear reciprocating motion without deterioration of straightness in the pressing process for transmitting the pressing force to the shaft 150 or the head bundle 150, or in the process of moving the head bundle and the shaft in the pressing force direction in response to the pressing force Induce.

Through this, the straightness of the shaft 150 may be prevented from being deteriorated, and the head bundle 140 includes the balls 141 to reduce the weight of the entire head bundle 140, thereby preventing a sudden increase in the pressure load.

As such, when forming a core part divided into the head bundle 140 and the shaft 150, the head bundle 140 may preferably have an enlarged diameter portion 142 having an expanded diameter as compared with the shaft 150.

The enlarged diameter portion 142 supports the second elastic body 170 through the enlarged diameter portion 142 without any support when the core portion is fitted along the spring receiving space 132 of the inner housing 130.

In this case, the front end of the shaft 150 may enter the guide hole 111 of the outer needle 110 across the second elastic body 170 seated in the spring receiving space 132 of the inner housing 130. It is desirable to adjust and set the overall length of 150.

When the tip of the shaft 150 is set by adjusting the length in a state where the guide hole 111 of the needle 110 is entered in the pressing force acting state on the second elastic body 170, the shaft 150 is a guide hole. It moves linearly along the guide hole 111 in the pressurizing action | atmosphere atmosphere or a pressurization progress, without leaving 111.

Accordingly, it is possible to secure the precise straightness of the shaft 150, through which the hair follicle 300 can be accurately implanted at the transplantation point of the hair follicle 300.

The outer diameter of the head bundle 140 is preferably assembled by adjusting the gap gap of the sliding contact surface to slide while contacting the inner diameter wall surface of the inner housing 130.

The gap clearance is important for maintaining the straightness of the shaft 150. If the gap is wide, the play is generated and thus the shake flow of the shaft 150 is generated. The clearance gap between the inner diameter wall surface of the inner housing 130 and the outer diameter surface of the head bundle 140 is preferably adjusted in the range of 0.1 to 0.5 mm.

Since the second elastic body 170 seated on the inner housing 130 may be in close contact with one end of the enlarged diameter part 142 formed on the head bundle 140, the second elastic body 170 may be attached to the inner housing 130. There is no need for a separate part to burn. It is completed with simple and concise joining structure.

As such, the first and second

elastic bodies

160 and 170 that are installed in the outer housing 120 and the inner housing 130 may include any kind of spring selected from a tension spring including a coil spring, a leaf spring, and a wire. .

Although the drawings show an example in which the coil springs are mounted in parallel in the outer housing 120 and the inner housing 120, respectively, but are not limited thereto. However, the coil spring may be selected as a preferred elastic body because it has a relatively good resiliency in compression and restoration in response to the pressing force and is advantageous in designing by adjusting the overall spring coefficient.

Referring to the state of use of the needle unit according to the invention configured as described above are as follows.

4 to 7 is an example in which the needle unit according to the present invention is mounted on the hair transplantation apparatus, but is not limited thereto.

After rotating to the center of the needle 110 is located in the center of the hair follicle discharge port 232, the hair follicle 300 can be implanted into the skin by adjusting the driving force of the movable part 220.

Needle unit 100 according to the present invention can be used simply mounted if manufactured to the standard of the cartridge unit 210. For example, the diameter and length of the needle unit may be determined and manufactured according to the diameter and the axial length of the channel hole 212. Referring to FIG. 7, the outer housing 120 of the needle unit 100 is mounted to the inner diameter of the channel hole 212 of the cartridge 211, and the length thereof is fitted to the axial length of the cartridge 211. An example is given.

The movable unit 220 selects one of the needle units 100 mounted in the channel hole 212 of the cartridge 211 and fits the needle 110 to the center of the hair follicle discharge port 232 formed in front of the case 231. It is a means for transplanting hair follicles by applying pressure to the hair follicle.

The movable unit 220 is coupled to the cartridge 211 and the rotating shaft 213 to select one of the needle unit 100 having the hair follicle 300 among the needle units 100 filled in the channel hole 212. To the cartridge drive motor 221 for rotating the cartridge 211 at a constant rotation angle, the slider module 222, the slider module 222 for transmitting the pressing force to the core portion of the needle unit 100 inserted into the cartridge 211 Pressing the core portion of the needle unit 100 in a linear motion in conjunction with the needle 110 to be sent to the hair follicle discharge port 232 to transplant the hair follicle 300 to the skin tissue and return to its original position after transplantation 223 It can be configured as.

Here, the slider module 222 may include a plurality of

sliders

224 and 225 to operate the reciprocating motion of the movable rod 223 step by step, and the plurality of

sliders

224 and 225 are respectively driven. The rotation of the

motors

226 and 227 is transferred to the movable rod 223 by converting the rotation of the motor 226 into a linear motion, through which the movable rod 223 transmits or releases the pressing force to the core of the needle unit 100.

The plurality of

sliders

224 and 225 allow the same linear reciprocating motion with respect to the single movable rod 223 while the plurality of

drive motors

226 and 227 transmit the pressing force to the core portion of the needle unit 100. The timing, the moving speed and the rotational torque may be set differently and adjusted.

In the cartridge type hair transplant apparatus 200 configured to accommodate the plurality of needle units 100, the cartridge type hair transplantation apparatus 200 may be inserted into the cartridge hole one by one into the channel hole for accommodating the needle unit 100.

An operation example of the needle unit according to an exemplary embodiment of the present invention will be described with reference to FIG. 8.

8 (a) (b) (c0 (d) (e) are explanatory diagrams of the hair follicle transplantation process and step-by-step operation of the needle unit according to the embodiment of the present invention.

(a) is a standby state before operation of the needle unit 100. As shown in (a), the needle unit 100 has the first elastic body 160 and the second elastic body mounted in the outer housing 120 and the inner housing 130 before the external pressure transmission by the movable part, that is, in the standby state of the procedure. All 170 are in tension.

(b) is the state in which the inner housing 130 of the needle unit 100 exits from the outer housing 120.

As shown in (b), when the needle unit 100 is moved for the procedure to approach the target point of the skin tissue 400 to transplant the hair follicles, the inner housing 130 is pressed when the inner housing 130 is pressed by the movable part. 1 The elastic body 160 moves in the direction of arrow A while overcoming the elasticity. The tip of the needle 100 penetrates primarily into the target skin tissue 400.

At this time, since the inner housing 130 operates along the outer housing 120, movement in a linear direction between movements is regulated to reach a target point with an accurate linear movement path, so that the tip of the needle 111 is exactly at a predetermined implantation point. To reach.

(c) is a state in which the hair follicle 300 inserted into the guide hole 111 of the needle 110 is implanted into the skin tissue while gradually decreasing the pressing force on the inner housing 130 of the needle unit 100.

When the pressing force on the inner housing 130 is reduced, the inner housing 130 in the outer housing 120 retreats in the elastic force action direction of the first elastic body by the elastic force of the first elastic body 160 as shown in (c). The shaft 150 entered into the guide hole 111 of the needle 110 may be retracted after staggering at the time when the hair follicle transplantation is completed.

At the same time, the pressing force is transmitted to the head bundle 140 mounted on the inner housing 130. The shaft 150 subjected to the pressing force advances in the direction of arrow B while overcoming the elastic force of the second elastic body 170 to the skin tissue point targeting the hair follicle 300 inserted into the guide hole 111 of the needle 110. Transplant.

At this time, the inner housing 130 supports and supports the rear portion of the shaft 150. Since the shaking flow of the shaft 150 is eliminated through the head bundle 140, there is no problem such that the hair follicle 300 is placed by shifting the implantation point. In other words, the hair follicles can be accurately implanted at a previously planned point.

(d) is the needle unit state immediately after completion of hair follicle transplantation. When transplantation of hair follicles is finished, when all the pressing forces on the inner housing 130 are released, the inner housing 130 moves to the arrow C direction and returns to an initial state by the elasticity of the first elastic body as shown in (d).

The release of the pressing force on the inner housing can be released instantaneously or in several divisions over time. When all of the pressing force that presses the inner housing is erased, the first elastic body 160, which is in the compressed state, is restored to the position of (a) in the initial state by the spring restoring force.

(e) is the needle unit state that returned to the initial state after completion of hair follicle transplantation.

When the pressing force on the head bundle 140 is released, the shaft 150 and the head bundle 140 move in the direction of arrow D as the spring restoring force of the second elastic body 170.

As such, when all the pressing force on the head bundle 140 is erased, only the hair follicle 300 escapes and is implanted into the skin tissue as compared with the initial state (a), so that the guide hole 111 of the needle 110 is emptied. It is in a waiting state to insert hair follicles into the space.
