Description

Cordless scalp punch device for hair follicle extraction

[0001] The present invention relates to a scalp punch device, and more particularly, to a scalp punch device that is provided wirelessly for hair follicle extraction.

[0002] Hair loss is a condition in which hair gradually falls out and thins due to factors such as aging, stress, and medication side effects. Hair loss can be caused by both genetic and acquired factors, such as stress. The number of people with hair loss has been steadily increasing, and this has led to ongoing development of hair loss treatment technologies.

[0003] Among hair loss treatments, hair transplantation involves extracting hair follicles remaining in the patient's skin tissue and then artificially implanting them into the area of ​​the scalp requiring hair transplantation. This involves using a scalp punch device to create an artificial wound in the scalp to extract the hair follicles.

[0004] Typically, a scalp punch device consists of a main body, a power cord that supplies power to the main body, and a punch handpiece that is connected to the main body via a wire and punches the scalp using the operator's hand movements. Due to the aforementioned structure, the scalp punch device occupies a considerable amount of space in the surgical space.

[0005] The operator must use their foot to step on a pedal connected to the main unit to operate the scalp punch device, which is inconvenient. Furthermore, the punch handpiece is connected to the main unit via a wire, and the main unit itself is connected to a power source via a power cord. This can restrict the movement of personnel (e.g., doctors and nurses) within the surgical space.

[0006] Furthermore, since the main body and punch handpiece are connected by a wire, the operator cannot freely move the position and adjust the angle of the punch handpiece. This may cause strain on the operator's body (e.g., wrist) during the relatively long hair transplant surgery. The aforementioned shortcomings of the scalp punch device can significantly affect the outcome of the hair transplant surgery.

[0007] The wireless scalp punch device for hair follicle extraction of the present disclosure is provided to solve these problems.

[0008] One of the problems to be solved by the present invention is to provide a wireless scalp punch device for hair follicle extraction that is compact and operates wirelessly, allowing people to move freely within a surgical space and reducing the burden on the operator's body (e.g., wrist) during a hair transplant surgery.

[0009] In addition, one of the problems to be solved by the present invention is to provide a wireless scalp punch device for hair follicle extraction that can provide consistency and ensure safety in the medical practice of punching the scalp.

[0010] In addition, one of the problems to be solved by the present invention is to provide a wireless scalp punch device for hair follicle extraction with improved structural reliability.

[0045] Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the attached drawings.

[0046] FIG. 1 is a front view of a wireless scalp punch device (10) according to an exemplary embodiment of the present disclosure. FIG. 2 is an exploded view of a wireless scalp punch device (10) according to an exemplary embodiment of the present disclosure. FIG. 3 is a block diagram of a wireless scalp punch device (10) according to an exemplary embodiment of the present disclosure.

[0047] The wireless scalp punch device (10) of the present disclosure is a scalp punch device provided wirelessly for hair follicle extraction, and may be a device that creates an artificial wound by piercing a portion of the scalp through a rotational motion of the tip to extract hair follicles from a subject. Specifically, the wireless scalp punch device (10) of the present disclosure may be a device that creates a cylindrical wound in a portion of the scalp where hair follicles are formed, for hair follicle extraction.

[0048] Referring to FIGS. 1 to 3 together, the wireless scalp punch device (10) for hair follicle extraction of the present disclosure may include a casing (110), a motor (120), a battery (130), a tip connecting member (140), a tip (150), a cap (160), a tip length adjusting member (170), a ring packing (180), a bearing (190), a grip ring (210), a first switch (220), a second switch (230), a display (240), a controller (250), an LED element (260), and a tip detection sensor (270). Hereinafter, components of the wireless scalp punch device (10) of the present disclosure will be described in more detail.

[0049] The casing (110) of the wireless scalp punch device (10) extends in a first direction and can accommodate a motor (120), a battery (130), a controller (250), etc. in an internal space. The first direction may be the same direction as the direction in which the tip (150) of the wireless scalp punch device (10) extends. In addition, the casing (110) may be a part of the wireless scalp punch device (10) that is held by the hand of a user (i.e., a practitioner).

[0050] In an exemplary embodiment, the casing (110) may be provided in a cylindrical shape having an internal space. However, the present invention is not limited thereto, and the casing (110) may also be provided in a polygonal cylindrical shape having an internal space.

[0051] In an exemplary embodiment, the casing (110) can accommodate a motor (120), a battery (130), and a controller (250) in an internal space, so that when the exterior of the assembled wireless scalp punch device (10) is observed, the motor (120), the battery (130), and the controller (250) may not be observed.

[0052] In an exemplary embodiment, a first switch (220), a second switch (230), and a display (240), which will be described later, may be provided on the side of the casing (110). Accordingly, a user can hold the casing (110) and operate the first switch (220) and the second switch (230) using a finger. In addition, the user can visually receive information of the wireless scalp punch device (10) through the display (240) disposed on the casing (110), and easily operate the first switch (220) and the second switch (230) based on the received information.

[0053] The motor (120) of the wireless scalp punch device (10) may be accommodated within the casing (110) and configured to rotate the motor shaft by power provided by the battery (130). The motor (120) may be accommodated within the internal space of the casing (110) such that the motor shaft extends in the first direction described above. In addition, the motor shaft may rotate around a rotation axis extending in the first direction.

[0054] In an exemplary embodiment, the rotational axis of the motor (120) may be coupled with a tip connecting member (140) to be described later. That is, the rotational force of the motor (120) is transmitted to the tip connecting member (140) and the tip (150), so that the tip connecting member (140) and the tip (150) may rotate together with the axis of the motor (120).

[0055] In an exemplary embodiment, the motor (120) may include a stepping motor configured to rotate at a constant angle based on a pressing operation of a first switch (220) described below.

[0056] The battery (130) of the wireless scalp punch device (10) may be a power supply configured to power the motor (120). In an exemplary embodiment, the battery (130) may include a lithium-ion battery. In one embodiment, when the battery (130) is discharged, the battery may be recharged through an external power source and reused. For example, the battery (130) may be charged by receiving power from an external power source through a charging cable coupled to the casing (110). However, the present invention is not limited thereto, and when the battery (130) is discharged, the battery may be replaced with a new battery.

[0057] The tip connecting member (140) of the wireless scalp punch device (10) may be a connecting shaft configured to connect the tip (150) and the motor (120). One side of the tip connecting member (140) may be connected to the motor shaft of the motor (120), and the other side of the tip connecting member (140), opposite to the one side, may be connected to the tip (150).

[0058] In an exemplary embodiment, the tip connecting member (140) may include a first connecting shaft (141) and a second connecting shaft (142). The first connecting shaft (141) may be a shaft provided on a portion of the tip connecting member (140) that has a groove that engages with the shaft of the motor (120). Additionally, the second connecting shaft (142) may be a shaft provided on another portion of the tip connecting member (140) that has a hole that is connected to the first connecting shaft (141) and engages with at least a portion of the tip (150).

[0059] In an exemplary embodiment, in order for the tip connecting member (140) to stably provide the rotational force of the motor (120) to the tip (150), the first connecting shaft (141) of the tip connecting member (140) needs to be firmly connected to the shaft of the motor (120). To this end, the tip connecting member (140) may include a flexible material. For example, the tip connecting member (140) may include a material such as rubber or silicone.

[0060] Accordingly, in the process of fitting the shaft of the motor into the groove of the first connecting shaft (141), the first connecting shaft (141) expands so that the shaft of the motor can be accommodated within the groove, and after the shaft of the motor is fitted into the groove of the first connecting shaft (141), the first connecting shaft (141) contracts so that it can be firmly attached to the shaft of the motor.

[0061] In addition, in order to secure flexibility of the first connecting axis (141), the width of the first connecting axis (141) (i.e., the length in the second direction perpendicular to the first direction, the vertical length in FIG. 2) may be provided to be smaller than the width of the second connecting axis (142).

[0062] In an exemplary embodiment, in the case of the second connecting shaft (142) that directly contacts the tip (150), there is a concern about physical damage to the second connecting shaft (142) due to friction with the tip (150). Accordingly, the second connecting shaft (142) may include a metallic material such as iron (e.g., stainless steel), and may include, for example, a material substantially the same as that of the tip (150). In addition, in order to secure structural reliability of the second connecting shaft (142), the width of the second connecting shaft (142) (i.e., the length in the second direction perpendicular to the first direction, the vertical length in FIG. 2) may be provided to be greater than the width of the first connecting shaft (141).

[0063] The tip (150) of the wireless scalp punch device (10) may be a part that is connected to a tip connecting member (140) and configured to punch the scalp using the rotational force of a motor (120). The punching motion may be defined as a motion in which the tip (150) creates an artificial wound on a portion of the scalp by the force with which the practitioner presses the tip (150) against the scalp and the rotational force of the tip (150) in order to extract hair follicles provided on the scalp of the subject.

[0064] The tip (150) may include a tip punch portion (151), a coupling restriction portion (152), and a tip coupling portion (153). The tip punch portion (151) may be a portion of the tip (150) that contacts the scalp of the operator and inflicts a wound on the scalp through rotation.

[0065] In an exemplary embodiment, the tip punch portion (151) may be provided in a columnar shape with an internal space. Accordingly, during the process of extracting hair follicles using the wireless scalp punch device (10), hair follicles overlapping the internal space of the tip punch portion (151) may not be physically damaged, and at least a portion of the scalp surrounding the hair follicles may be pierced.

[0066] In an exemplary embodiment, the tip coupling portion (153) may be a portion of the tip (150) that is fitted into a hole provided in the second coupling axis (142) of the tip coupling member (140).

[0067] In an exemplary embodiment, the coupling limiting portion (152) may be provided between the tip punch portion (151) and the tip coupling portion (153), and may be a portion of the tip (150) that limits an insertion length of the tip (150) within a space provided by the tip coupling member (140) when the tip (150) is inserted into the tip coupling member (140). The width of the coupling limiting portion (152) (i.e., the length in the second direction perpendicular to the first direction, the vertical length in FIG. 2) may be provided to be greater than the widths of the tip punch portion (151) and the tip coupling portion (153). Accordingly, only the tip coupling portion (153) may be coupled to the internal space of the tip coupling member (140), and the tip punch portion (151) may be exposed from the tip coupling member (140) without being coupled to the internal space of the tip coupling member (140).

[0068] In an exemplary embodiment, the coupling restriction portion (152) may be provided in a truncated cone shape. In addition, the coupling restriction portion (152) may have a discharge hole on the surface. Accordingly, during the process of extracting hair follicles using the wireless scalp punch device (10), blood and scalp moved into the internal space of the tip punch portion (151) may be discharged through the discharge hole of the coupling restriction portion (152). Since the blood and scalp may be easily discharged through the discharge hole, the rotation of the tip (150) may not be restricted due to the blood and scalp, and the blood may not coagulate in the internal space of the tip (150).

[0069] However, the invention is not limited thereto, and as will be described later, the tip punch portion (151) may only have a discharge hole, and the coupling restriction portion (152) may not have a discharge hole. In addition, both the tip punch portion (151) and the coupling restriction portion (152) of the tip (150) of the present disclosure may not have a discharge hole.

[0070] The cap (160) of the wireless scalp punch device (10) may be coupled to the casing (110) so as to surround at least a portion of the tip connecting member (140). In an exemplary embodiment, the tip connecting member (140) may have a tapered structure in which the width (i.e., the length in the second direction perpendicular to the first direction, the vertical length in FIG. 2) increases as it moves away from the tip (150) (i.e., as it moves closer to the casing (110). For example, the cap (160) may be provided in a frusto-conical shape, but the shape is not limited thereto.

[0071] Additionally, one side of the cap (160) of the wireless scalp punch device (10) can be coupled to either the casing (110) or the phage ring (210) described later. Additionally, the other side of the cap (160), opposite to the one side described above, can be coupled to the tip length adjustment member (170) described later.

[0072] In an exemplary embodiment, the cap (160) may have a plurality of curved protrusions protruding from the surface. The plurality of curved protrusions may be fitted into the receiving groove of the tip length adjustment member (170). The technical idea will be described in more detail below.

[0073] Unlike the above, the cap (160) may have a screw thread protruding from the surface. The screw thread may be rotatably engaged with the receiving groove of the tip length adjustment member (170). The technical idea will be described in more detail below.

[0074] The tip length adjustment member (170) of the wireless scalp punch device (10) can be coupled with the cap (160) to surround at least a portion of the tip (150). In addition, the tip length adjustment member (170) can be configured to adjust the exposure length of the tip punch portion (151) of the tip (150) based on the coupling position with the cap (160).

[0075] In an exemplary embodiment, for easy coupling between the tip length adjustment member (170) and the cap (160), the tip length adjustment member (170) may have a tapered structure in which the width (i.e., the length in the second direction perpendicular to the first direction, the vertical length in FIG. 2) increases as it moves away from the tip (150) (i.e., as it moves closer to the casing (110). For example, the tip length adjustment member (170) may be provided in a truncated cone shape, but the shape is not limited to that described above.

[0076] Additionally, in an exemplary embodiment, to facilitate adjustment of the coupling position between the tip length adjustment member (170) and the cap (160), the tip length adjustment member (170) may include a flexible material. For example, the material of the tip length adjustment member (170) may include rubber or silicone.

[0077] The ring packing (180) of the wireless scalp punch device (10) is a packing provided in a ring shape and can wrap a portion of the tip (150). For example, the ring packing (180) may be a rubber packing or a silicone packing.

[0078] In an exemplary embodiment, the ring packing (180) may be coupled to the tip coupling portion (153) of the tip (150) in the internal space of the cap (160). Accordingly, the blood of the subject of the treatment generated during a punching operation using the wireless scalp punch device (10) of the present disclosure may not be injected into the internal space of the tip connection member (140) and may not flow along the outer surface of the tip connection member (140). Accordingly, electrical components such as the motor (120), the battery (130), and the controller (250) may be protected from the blood of the subject of the treatment, thereby improving the operational reliability of the wireless scalp punch device (10) of the present disclosure.

[0079] The bearing (190) of the wireless scalp punch device (10) can be accommodated in the casing (110) and can rotatably support the tip connecting member (140). That is, the bearing (190) can rotatably support the tip connecting member (140) while receiving the load of the tip connecting member (140).

[0080] Additionally, the bearing (190) may include a first bearing portion (191) and a second bearing portion (192). In an exemplary embodiment, the first bearing portion (191) may rotatably support a first connecting shaft (141) of the tip connecting member (140).

[0081] In an exemplary embodiment, in order for the bearing (190) to be firmly fixed within the inner space of the casing (110), the first bearing portion (191) may include a fixing projection (191P) that is inserted into a groove formed on the inner surface of the casing (110). Accordingly, the bearing (190) may be firmly fixed within the casing (110) and may rotatably support the tip connecting member (140). For example, the first bearing portion (191) may be provided in a hollow cylindrical shape.

[0082] In an exemplary embodiment, the second bearing portion (192) may extend helically from the first bearing portion (191) to rotatably support the second connecting shaft (142).

[0083] The grip ring (210) of the wireless scalp punch device (10) may be a ring that is coupled between the casing (110) and the cap (160) to facilitate gripping by the practitioner. In order to increase the frictional force between the practitioner's hand and the wireless scalp punch device (10) when the practitioner grips the device, the grip ring (210) may be formed with a rough structure having repeated concave and convex portions on its surface. For example, the surface of the grip ring (210) may have a mesh structure.

[0084] The first switch (220) of the wireless scalp punch device (10) may be provided on one side of the casing (110). The first switch (220) may be a push switch and may control the on / off of the motor (120) based on the pressing of the operator. That is, the first switch (220) may control the rotational motion of the motor (120) based on the pressing of the operator. For example, when the motor (120) includes a stepping motor, the first switch (220) may control the stepping motor to rotate by a predetermined angle.

[0085] The second switch (230) of the wireless scalp punch device (10) may be provided at the rear of the casing (110). The second switch (230) may be coupled to the casing (110) so as to be rotatable and pressable at the end of the casing (110).

[0086] In an exemplary embodiment, when the second switch (230) rotates, the rotation speed of the motor (120) (i.e., the rotation speed of the tip (150)) can be controlled based on the rotation amount of the second switch (230). For example, when the second switch (230) rotates in a first rotation direction, the rotation speed of the motor (120) can gradually increase, and when the second switch (230) rotates in a second rotation direction opposite to the first rotation direction, the rotation speed of the motor (120) can gradually decrease.

[0087] In an exemplary embodiment, the rotational direction of the motor (120) may be controlled based on the push of the second switch (230). For example, when the second switch (230) is pressed while the motor (120) is rotating in the first rotational direction, the motor (120) may rotate in the second rotational direction opposite to the first rotational direction.

[0088] The display (240) of the wireless scalp punch device (10) may be a display provided on the casing (110) to visually provide information on the operation of the wireless scalp punch device (10). Accordingly, the operator can check the operation information of the wireless scalp punch device (10) provided on the casing (110) in real time and easily operate the first switch (220) and the second switch (230) provided on the casing (110) based on the operation information.

[0089] In an exemplary embodiment, the display (240) may display on / off information of the wireless scalp punch device (10) and the number of rotations (i.e., rotation count) of the motor (120) based on the pressing operation of the first switch (220). In a hair transplant surgery, it may be important to calculate how many hair follicles are extracted from the scalp of the operator. Since the display (240) of the present disclosure may display the number of rotations of the motor (120) based on the pressing operation of the first switch (220) (i.e., the number of motor operations or the motor rotation count), the operator can easily calculate how many hair follicles are extracted by referring to the display (240).

[0090] In addition, the display (240) can display information on the rotation direction of the motor (i.e., the first rotation direction or the second rotation direction) based on the pressing operation of the second switch (230), and information on the rotation speed of the motor (120) based on the rotation operation of the second switch (230). Accordingly, the operator can easily adjust the rotation direction and rotation speed of the motor (120) by operating the second switch (230) with reference to the information displayed on the display (240).

[0091] The controller (250) can control the operation of the wireless scalp punch device (10) of the present disclosure. In an exemplary embodiment, the controller (250) can be connected to a motor (120), a first switch (220), a second switch (230), a display (240), an LED element (260), and a tip detection sensor (270). For example, the controller (250) can be a control board including a substrate such as a PCB substrate.

[0092] In an exemplary embodiment, the controller (250) can control the on / off, rotation direction, rotation speed, etc. of the motor (120) based on the operation of the first switch (220) and the second switch (230).

[0093] In addition, the controller (250) can control the display (240) so that information related to the operation of the wireless scalp punch device (10) is displayed on the display (240). In addition, the controller (250) can control the on / off of the LED element (260) during the punch operation. In addition, the controller (250) can receive information on the length of the exposed tip from the tip detection sensor (270) and control the motor based on the information.

[0094] In an exemplary embodiment, the controller (250) may perform a blood coagulation mode of the wireless scalp punch device (10). When performing a punching operation using the wireless scalp punch device (10), the blood of the subject may seep into the interior of the wireless scalp punch device (10) and coagulate. In this case, the rotational speed of the motor (120) may decrease, thereby reducing the efficiency of the hair follicle extraction surgery using the wireless scalp punch device (10).

[0095] To this end, the controller (250) of the present disclosure can perform a blood coagulation mode. Specifically, when the rotation speed of the motor decreases below a first reference speed, the controller (250) can provide a notification of a mode change to the display (240). After the notification of the mode change is provided, when the controller (250) receives a pressing input of the first switch (220) from the operator, the rotation speed of the motor (120) can be increased without operating the second switch (230). Accordingly, even when the blood of the subject seeps into the interior of the wireless scalp punch device (10) and coagulates, the operator can increase the rotation speed of the motor (120) by operating the first switch (220), which is relatively more convenient to operate than the second switch (230), thereby improving the efficiency of the hair follicle extraction surgery.

[0096] Additionally, the wireless scalp punch device (10) may further include a memory. The memory may store data necessary for performing the operation of the wireless scalp punch device (10) of the present disclosure.

[0097] The LED element (260) of the wireless scalp punch device (10) is provided on the cap (160) and can be turned on / off based on any one of the operations of the first switch (220), the operation of the second switch (230), and the combined operation of the first switch (220) and the second switch (230). Since the wireless scalp punch device (10) can include the LED element (260), the convenience of the operator during the hair follicle extraction surgery can be improved by the light provided by the LED element (260) during the hair follicle extraction surgery using the wireless scalp punch device (10).

[0098] In an exemplary embodiment, the tip detection sensor (270) can detect at least one of the exposure length of the tip (150), the engagement length of the tip (150), and the type of the tip (150). For example, the tip detection sensor (270) can include a distance measurement sensor to detect at least one of the length of the tip engagement portion (153), the length of the tip punch portion (151), and the length between the tip (150) and the tip detection sensor (270).

[0099] In an exemplary embodiment, the tip detection sensor (270) can transmit the detected information to the controller (250), and the controller (250) can calculate the rotational speed of the motor (120) based on the received information.

[0100] The wireless scalp punch device (10) of the present disclosure may include a motor (120), a battery (130), a controller (250), etc. provided within a casing (110), so that the wireless scalp punch device (10) of the present disclosure may be operated wirelessly and may have a reduced volume. Accordingly, the wireless scalp punch device (10) of the present disclosure may enable free movement of people within a surgical space and reduce the burden on the operator's body (e.g., wrist) during a hair transplant surgery.

[0101] In addition, since the wireless scalp punch device (10) of the present disclosure can have a combined structure of a tip (150), a tip connecting member (140), and a motor (120), the wireless scalp punch device (10) can provide consistency and ensure safety in the medical practice of punching the scalp.

[0102] In addition, since the wireless scalp punch device (10) of the present disclosure can have the above-described coupling structure, the structural reliability of the wireless scalp punch device (10) of the present disclosure can be improved.

[0103] FIG. 4 is a diagram showing a scalp punch device (10') according to a comparative example of the present disclosure and a scalp punch device (10) according to an exemplary embodiment of the present disclosure from a planar perspective.

[0104] FIG. 4 may be a drawing of the scalp punch device (10') according to the comparative example and the scalp punch device (10) of the present disclosure observed from a planar perspective after the tip (150) of the scalp punch device (10') according to the comparative example and the scalp punch device (10) of the present disclosure are placed in the same line as the naked eye of the observer.

[0105] Referring to (a) of FIG. 4, when the scalp punch device (10') according to the comparative example is observed from a planar perspective, a gap space can be observed between the tip (150) and the tip length adjustment member (170).

[0106] In this case, the blood of the subject resulting from the medical procedure of punching the scalp may seep into the above-mentioned space and contaminate the motor (120), battery (130), and controller (250).

[0107] In addition, in the case of the scalp punch device (10') according to the comparative example, if the tip (150) and the tip connecting member (140) are not firmly connected, the tip (150) may shake left and right or up and down within the space, which may not provide consistency in the medical act of punching the scalp.

[0108] Referring to (b) of FIG. 4, the wireless scalp punch device (10) of the present disclosure may include a ring packing (180) coupled to the tip coupling portion (153) of the tip (150) in the internal space of the cap (160). For example, the ring packing (180) may be a rubber packing or a silicone packing. That is, when the scalp punch device (10) of the present disclosure is viewed from a planar perspective, the ring packing (180) of the present disclosure may block the separation space according to the comparative example.

[0109] Accordingly, the blood of the subject of the treatment generated during the punching operation using the wireless scalp punch device (10) of the present disclosure may not be injected into the internal space of the tip connection member (140) by the ring packing (180) and may not flow along the outer surface of the tip connection member (140). Accordingly, the electrical components such as the motor (120), battery (130), and controller (250) are protected from the blood of the subject of the treatment, and the operational reliability of the wireless scalp punch device (10) of the present disclosure may be improved.

[0110] In addition, the ring packing (180) of the present disclosure can strengthen the bond between the tip (150) and the tip connecting member (140), thereby preventing the tip (150) from shaking left and right or up and down within the separation space, thereby providing consistency in the medical practice of punching the scalp.

[0111] FIG. 5 is a drawing showing a joint structure between a cap (160) and a tip length adjustment member (170) according to an exemplary embodiment of the present disclosure.

[0112] Referring to (a) of FIG. 5, the cap (160) of the present disclosure may have a plurality of curved protrusions (160p1) protruding from the surface. The plurality of curved protrusions may be fitted into receiving grooves provided within the tip length adjusting member (170).

[0113] In an exemplary embodiment, a plurality of curved protrusions (160p1) are provided, each of which can be spaced apart from each other along a first direction, so that the tip length adjustment member (170) can be coupled to any one of the plurality of curved protrusions (160p1). Based on the position of the curved protrusion (160p1) to which the tip length adjustment member (170) is coupled, the length of the tip (150) exposed from the end of the tip length adjustment member (170) can be adjusted.

[0114] In an exemplary embodiment, the curved protrusion (160p1) may be provided in a curved shape, such as a wave pattern. In addition, the receiving groove of the tip length adjustment member (170) may also be provided in a correspondingly curved shape, such as a wave pattern. Since the curved protrusion (160p1) of the cap (160) may be provided in a curved shape, the reliability of the connection between the cap (160) and the tip length adjustment member (170) may be improved compared to a case where the protrusion is provided in a straight shape.

[0115] Referring to (b) of FIG. 5, the cap (160) of the present disclosure may have a screw thread (160p2) protruding from the surface. The screw thread (160p2) may be rotatably coupled to a receiving groove provided inside the tip length adjusting member (170).

[0116] In an exemplary embodiment, the cap (160) may have a thread (160p2) such that the length of the tip (150) exposed from the end of the tip length adjusting member (170) may be adjusted based on the amount of rotation of the tip length adjusting member (170).

[0117] FIG. 6 is a drawing showing a joint structure of a tip connecting member (140) and a motor (120) according to an exemplary embodiment of the present disclosure.

[0118] Referring to FIG. 6, the tip connecting member (140) may include a first connecting shaft (141) and a second connecting shaft (142). The first connecting shaft (141) may be a shaft provided on a portion of the tip connecting member (140) that has a groove that is coupled with the shaft of the motor (120). In addition, the second connecting shaft (142) may be a shaft provided on another portion of the tip connecting member (140) that is coupled with the first connecting shaft (141) and has a hole that is coupled with at least a portion of the tip (150).

[0119] In an exemplary embodiment, in order for the tip connecting member (140) to stably provide the rotational force of the motor (120) to the tip (150), the first connecting shaft (141) of the tip connecting member (140) needs to be firmly connected to the shaft (120S) of the motor (120).

[0120] To this end, the tip connecting member (140) may include a flexible material. For example, the tip connecting member (140) may include a material such as rubber or silicone. Accordingly, in the process of fitting the shaft (120S) of the motor into the groove of the first connecting shaft (141), the first connecting shaft (141) may expand so that the shaft (120S) of the motor may be accommodated within the groove, and after the shaft (120S) of the motor is coupled to the groove of the first connecting shaft (141), the first connecting shaft (141) may contract so that it may be firmly attached to the shaft of the motor.

[0121] In addition, the shape of the cross-section of the groove (141G) of the first connecting shaft (141) of the tip connecting member (140) may be substantially the same as the shape of the cross-section of the shaft (120S) of the motor (120). In an exemplary embodiment, for a firm connection of the motor (120) and the tip connecting member (140), the cross-section of the shaft (120S) of the motor (120) may be provided in a shape such as a cross or a polygon, and the groove (141G) of the first connecting shaft (141) may also be provided in a corresponding shape.

[0122] FIG. 7 is a drawing showing an LED element (260) according to an exemplary embodiment of the present disclosure.

[0123] Referring to FIG. 7, the LED element (260) of the wireless scalp punch device (10) is provided on the cap (160) and can be turned on / off based on any one of the operations of the first switch (220), the operation of the second switch (230), and the combined operation of the first switch (220) and the second switch (230).

[0124] Additionally, a plurality of LED elements (260) may be provided, each of which may emit light in a different color. However, the present invention is not limited thereto, and each of the LED elements (260) may emit light in the same color.

[0125] Since the wireless scalp punch device (10) can include an LED element (260), the convenience of the operator can be improved during hair follicle extraction surgery by the light provided by the LED element (260) during hair follicle extraction surgery using the wireless scalp punch device (10).

[0126] In an exemplary embodiment, the LED element (260) of the present disclosure may be configured to emit light in a different color than the color it previously emitted when the operation of the wireless scalp punch device (10) changes based on the input of the first switch (220) and the second switch (230).

[0127] For example, when the motor (120) rotates in the first rotation direction, the LED element (260) can emit a first color, and when the rotation direction of the motor (120) is changed to the second rotation direction by the second switch (230), the LED element (260) can emit a second color different from the first color.

[0128] In an exemplary embodiment, the LED element (260) of the present disclosure may be configured to emit light with an intensity different from the existing intensity when the operation of the wireless scalp punch device (10) changes. For example, when the motor (120) rotates at a first speed, the LED element (260) may emit light with the first intensity. At this time, when the rotation speed of the motor (120) is rotated at a second speed that is slower than the first speed by the second switch (230), the LED element (260) may emit light with a second intensity that is weaker than the first intensity. In addition, when the rotation speed of the motor (120) is rotated at a third speed that is faster than the first speed by the second switch (230), the LED element (260) may emit light with a third intensity that is greater than the first intensity.

[0129] Accordingly, the user can easily check the change in operation status of the wireless scalp punch device (10) through the LED element (260).

[0130] FIG. 8 is an enlarged view of a tip punch portion (151) of a tip (150) according to an exemplary embodiment of the present disclosure.

[0131] Referring to FIG. 8, the tip punch portion (151) may be a portion of the tip (150) that contacts the scalp of the operator and inflicts a wound on the scalp through rotation.

[0132] In an exemplary embodiment, the tip punch portion (151) may be provided in a columnar shape with an internal space. Accordingly, during the process of extracting hair follicles using the wireless scalp punch device (10), hair follicles overlapping the internal space of the tip punch portion (151) may not be physically damaged, and at least a portion of the scalp surrounding the hair follicles may be pierced.

[0133] In an exemplary embodiment, the tip punch portion (151) may have a plurality of discharge holes (151H) on the surface. Accordingly, blood and scalp that have moved into the internal space of the tip punch portion (151) during the process of extracting hair follicles using the wireless scalp punch device (10) may be discharged through the discharge holes (151H). Since the blood and scalp may be easily discharged through the discharge holes (151H), the rotation of the tip (150) may not be restricted by the blood and scalp, and the blood may not coagulate in the internal space of the tip (150).

[0134] In an exemplary embodiment, the discharge hole (151H) may be provided in an elliptical shape extending in a first direction, which is the extension direction of the tip (150). However, the shape of the discharge hole (151H) is not limited thereto. In addition, although a plurality of discharge holes (151H) are illustrated in FIG. 8, the discharge hole (151H) may be provided as a single discharge hole.

[0135] FIG. 9 is a diagram showing the operation of a wireless scalp punch device according to an exemplary embodiment of the present disclosure.

[0136] Referring to FIG. 9, the tip punch portion (151) of the wireless scalp punch device (10) according to an exemplary embodiment of the present disclosure may be configured to punch the scalp (SP) using the rotational force of the motor (120). The punching motion may be defined as a motion in which the tip punch portion (151) makes an artificial wound on a portion of the scalp (SP) by the force with which the practitioner presses the tip punch portion (151) against the scalp (SP) and the rotational force of the tip punch portion (151) to extract hair follicles (HF) provided on the scalp of the subject.

[0137] In an exemplary embodiment, the tip punch portion (151) may be provided in a columnar shape having an internal space. Accordingly, during the process of extracting hair follicles (HF) using the wireless scalp punch device (10), the hair follicles (HF) overlapping the internal space of the tip punch portion (151) may not be physically damaged, and at least a portion of the scalp (SP) surrounding the hair follicles (HF) may be pierced. After performing the punching operation of the present disclosure, the hair follicles (HF) may be extracted using a separate forceps device.

[0138] In an exemplary embodiment, the wireless scalp punch device (10) of the present disclosure may be operated in multiple modes. For example, the wireless scalp punch device (10) of the present disclosure may be operated in a blood coagulation mode.

[0139] When performing a punching operation using a wireless scalp punch device (10), the blood of the subject may seep into the interior of the wireless scalp punch device (10) and coagulate. In this case, the rotational speed of the motor (120) may decrease, thereby reducing the efficiency of the hair follicle extraction surgery using the wireless scalp punch device (10). To this end, the wireless scalp punch device (10) of the present disclosure may operate in a blood coagulation mode.

[0140] Specifically, the wireless scalp punch device (10) can provide a notification of a mode change on the aforementioned display (240) when the rotation speed of the motor decreases below the first reference speed. After the notification of the mode change is provided, when the wireless scalp punch device (10) receives a pressing input of the first switch (220) by the operator, the rotation speed of the motor (120) can be increased without operating the second switch (230).

[0141] Accordingly, even if the blood of the subject seeps into the interior of the wireless scalp punch device (10) and coagulates, the operator can improve the efficiency of the hair follicle extraction surgery by increasing the rotation speed of the motor (120) by operating the first switch (220), which is relatively more convenient to operate than the second switch (230).

[0142] FIG. 10 is a drawing showing a wireless scalp punch device (30) according to an exemplary embodiment of the present disclosure.

[0143] The wireless scalp punch device (30) of the present disclosure may include a motor, a battery, a tip connecting member, a tip, a cap, and the like. Hereinafter, overlapping details with the wireless scalp punch device (10) described with reference to FIGS. 1 to 9 will be omitted, and differences will be primarily described.

[0144] Specifically, the wireless scalp punch device (30) of the present disclosure may include a casing (310) having an internal space and extending in one direction to be gripped by a user, a motor accommodated in the internal space of the casing (310), a battery accommodated in the internal space of the casing (310) and configured to supply power to the motor, a tip connecting member (340) having one side coupled to a rotational axis of the motor, and a cap (360) configured to surround at least a portion of the tip connecting member (340) and adjust an exposure length of the tip through rotational coupling with a screw line provided on the tip connecting member (340).

[0145] The wireless scalp punch device (30) of the present disclosure can adjust the length of the tip (350) exposed from the cap (360) through the rotational coupling of the cap (360) and the tip connecting member (340). That is, the wireless scalp punch device (30) of the present disclosure can adjust the exposed length of the tip (350) even without the tip length adjusting member (170) described above.

[0146] In an exemplary embodiment, the tip connecting member (340) may include a grip fitting shaft (341) that is engaged with the casing (310), a tip fitting shaft (342) that extends from the grip fitting shaft (341) and has a thread (342P) on the surface for engaging the tip, and a blocking plate (343) that is provided between the grip fitting shaft (341) and the tip fitting shaft (342) and is in contact with the casing (310).

[0147] Referring to (a) of FIG. 10, a collet chuck (370) may be inserted into a tip fitting shaft (342) of the tip connecting member (340) to secure the tip (350) to the tip connecting member (340). The collet chuck (370) may have an opening that can be changed to various sizes to insert various types of tips (350).

[0148] Thereafter, the tip (350) can be inserted into the opening of the collet chuck (370), and the opening can be tightened as the fixing member (380) is rotationally coupled with at least a portion of the collet chuck (370). Accordingly, the collet chuck (370) and the tip (350) can be firmly coupled. For example, the fixing member (380) can employ a nut.

[0149] Referring to (b) of FIG. 10, after the tip (350) is coupled to the hole of the tip fitting shaft (342), the cap (360) can be rotationally coupled with the screw thread (342P) of the tip fitting shaft (342). Specifically, the cap (360) can have a screw groove corresponding to the screw thread (342P) of the tip fitting shaft (342) on the inside.

[0150] In an exemplary embodiment, the engagement position of the cap (360) and the screw thread (342P) can be adjusted based on the degree of rotation of the cap (360). Accordingly, the length of the tip (350) protruding and exposed from the cap (360) can be adjusted.

[0151] Referring to (c) of Fig. 10, after the exposure length of the tip (350) is adjusted by rotation of the cap (360), the casing (310) can be fitted into the phage fitting shaft (341).

[0152] Accordingly, the wireless scalp punch device (30) of the present disclosure can adjust the exposure length of the tip (350) even without the tip length adjustment member (170) described above.

[0153] As described above, exemplary embodiments have been disclosed in the drawings and specifications. While specific terminology has been used to describe embodiments herein, it is intended solely to illustrate the technical concept of the present disclosure and is not intended to limit the scope of the present disclosure as defined in the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present disclosure should be determined by the technical concept of the appended claims.
