Description

Technical Field

[0001] This invention belongs to the field of permanent makeup, specifically relating to an ultrasound-guided permanent makeup device. Background Technology

[0002] The skin is the largest organ in the human body, covering the outermost layer of the body surface. It has seven main functions: respiration, excretion, temperature regulation, absorption, metabolism, protection, and sensation. Its weight is 5%-15% of the body weight, and adult skin is approximately 2 mm thick. Its thickness is between 0.54 mm, although this varies depending on the location of the body. The skin consists of three layers from the outside in: the epidermis, dermis, and subcutaneous tissue.

[0003] In traditional permanent makeup devices, the practitioner moves the needle across the skin according to the desired effect, adjusting the pressure applied to the skin to change the skin's layers. Therefore, permanent makeup requires a high level of skill; less experienced practitioners often struggle to control the pressure to achieve the desired results.

[0004] Because traditional permanent makeup needles cannot determine the depth of insertion, practitioners cannot control the pressure according to the desired effect and deliver the pigment to the corresponding skin layers. As a result, some practitioners may blindly increase the pressure or cut open the skin to repeatedly apply color in order to ensure the effect, which may lead to color bleeding or even scarring in the later stages of the work.

[0005] The above situation has led to a significant increase in complaints from beauty clients, as well as a substantial rise in related civil cases and administrative complaints, thus proving that traditional permanent makeup techniques using needles to apply semi-permanent pigments are no longer adequate for market needs. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrasound-guided permanent makeup device, which solves the problem that existing traditional permanent makeup needles cannot determine the insertion depth and therefore cannot deliver the pigment to the corresponding skin layers according to the needs of the permanent makeup effect.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an ultrasound-guided permanent makeup device, comprising: a pen body, a probe mechanism, and a main body; characterized in that,

[0008] The pen body is a hollow cylindrical structure with openings at both ends. The outer surface has a slot, and the inside has a needle and a moving mechanism connected to the needle. The permanent makeup pigment enters the pen body through the tail opening, and the moving mechanism drives the needle to move in and out along the front opening by controlling the extension length of the needle.

[0009] The probe mechanism consists of a probe tube and a detection and scanning component located inside the probe tube. The surface of the probe tube has a protrusion, which cooperates with the slot to make the front end of the probe tube and the front end of the pen body on the same horizontal plane.

[0010] The detection and scanning assembly consists of an acoustic lens, a matching layer, a piezoelectric ceramic layer formed by multiple array elements arranged at intervals, and a backing material layer arranged sequentially from the front end to the rear end of the detection tube; the detection and scanning assembly also includes a cable for applying pulse excitation to the piezoelectric ceramic layer and leads for receiving electrical signals from both ends of the piezoelectric ceramic layer.

[0011] The main body consists of a computer system, which includes at least a display, an operating keyboard, and a host. The host includes an ultrasound imaging module and a data acquisition module. The host sends instructions and receives image data through at least one lead wire, and forms a skin layer image based on the image data; and controls the start and stop of the moving mechanism through at least one electrical control wire.

[0012] Furthermore, mobile institutions also include:

[0013] The motion plate has a reciprocating linear motor mounted on its upper surface, and the output shaft of the reciprocating linear motor is fixedly connected to the needle through a connecting block; the reciprocating linear motor is used to drive the needle to perform reciprocating motion.

[0014] The ball screw assembly consists of a screw and ball bearings. The two ends of the screw are fixed in the pen body along the axis of the pen body, and the ball bearings are connected to the motion plate to control the extension length of the needle by controlling the movement of the motion plate. The ball screw assembly also includes a screw motor, which receives start and stop commands from the host computer through an electrical control line.

[0015] Furthermore, the pen body consists of a front section, a rear section, and a middle section. The two ends of the middle section are threaded to the front section and the rear section, respectively. Inside the middle section, multiple small tubes are placed in parallel, and each small tube contains a type of pigment.

[0016] The mixing cylinder, located inside the middle section cylinder, is connected to multiple smaller cylinders and is equipped with a stirring mechanism. The stirring mechanism is used to stir the pigment flowing from the multiple smaller cylinders into the mixing cylinder and push it into the needle.

[0017] Furthermore, the stirring mechanism includes:

[0018] The stirring roller shaft consists of a rotor motor and an impeller connected to the motor shaft. A protective cover is also provided on the motor shaft to prevent pigment from contaminating the rotor motor.

[0019] The lifting frame, located at the bottom of the rotor motor, is equipped with an electric telescopic rod that enables the stirring roller shaft to move up and down. It is used to seal the bottom opening of the mixing cylinder with a protective cover when the stirring roller shaft is working.

[0020] Furthermore, the stirring mechanism also includes:

[0021] The three-way pipe is located at the bottom of the lifting frame and has a first port, a second port and a third port. The first port is used to collect the pigment passing through the lifting frame. The second port is set at an angle greater than 90 degrees to the first port. At the same time, a movable piston is also installed in the pipe connected to the second port. The piston is used to push the pigment to the third port. The third port is connected to the needle through an elastic threaded ring.

[0022] Furthermore, multiple spiral propulsion rods are installed in the rear section of the cylinder corresponding to multiple small cylinders. At the same time, a pusher frame is also provided in the rear section of the cylinder. The pusher frame pushes each spiral propulsion rod into the small cylinder, and the amount of pigment flowing into the mixing cylinder from each small cylinder is controlled by the rotation of each spiral propulsion rod.

[0023] Furthermore, the front end of each spiral propeller is spiked, and the front end of each small tube is equipped with a sealing balloon that can be punctured by the front end of the spiral propeller.

[0024] Furthermore, the pushing frame is propelled by an electrically operated telescopic rod.

[0025] Furthermore, the middle section of the cylinder is also equipped with a mounting frame that allows multiple small cylinders to be placed in parallel. The mounting frame consists of a chuck that holds the small cylinders in place and a flow plate located at the front end of the small cylinders. Multiple conical blind holes are provided on the flow plate corresponding to the multiple small cylinders. Each conical blind hole has a through hole on its side wall. The through hole is used to prevent pigment from clogging.

[0026] The present invention has the following beneficial effects:

[0027] The protrusions on the pen body and the grooves on the probe tube ensure that the front end of the pen body and the front end of the probe tube are at the same level as the patient's skin. This allows the detection and scanning component to obtain the puncture depth of the needle inside the pen body. At the same time, the main body controls the moving mechanism to maintain an appropriate extension length when the needle extends. When the practitioner performs semi-permanent makeup, the needle will not excessively puncture the skin. The practitioner can also observe whether the needle is puncturing too shallowly through the skin layer image on the main body. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0037] An ultrasound-guided permanent makeup device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: pen body, probe mechanism, and main body; the angles of the probe cylinder and probe are redrawn.

[0038] The pen body is a hollow cylindrical structure with openings at both ends. The outer surface is provided with a slot, and the inside is provided with a needle 500 and a moving mechanism connected to the needle 500. The permanent makeup pigment enters the pen body through the tail opening, and the moving mechanism drives the needle 500 to move in and out along the front opening by controlling the extension length of the needle 500.

[0039] The probe mechanism consists of a probe cylinder 400 and a probe scanning component located inside the probe cylinder 400. The surface of the probe cylinder 400 is provided with a protrusion, which cooperates with the slot to make the front end of the probe cylinder 400 and the front end of the pen body on the same horizontal plane.

[0040] The detection and scanning assembly consists of an acoustic lens 450, a matching layer 420, a piezoelectric ceramic layer 440 formed by multiple array elements arranged at intervals, and a backing material layer 430 arranged sequentially from the front end to the rear end of the detection cylinder 400; the detection and scanning assembly also includes a cable 410 for applying pulse excitation to the piezoelectric ceramic layer 440 and leads for receiving electrical signals at both ends of the piezoelectric ceramic layer 440.

[0041] The main body consists of a computer system, which includes at least a display, an operating keyboard, and a host. The host includes an ultrasound imaging module and a data acquisition module. The host sends instructions and receives image data through at least one lead wire, and forms a skin layer image based on the image data; and controls the start and stop of the moving mechanism through at least one electrical control wire.

[0042] The protrusions on the pen body and the grooves on the probe cylinder 400 ensure that the front end of the pen body and the front end of the probe cylinder 400 are at the same level as the patient's skin. This allows the detection and scanning component to obtain the puncture depth of the needle 500 inside the pen body. At the same time, the main body controls the moving mechanism to ensure that the needle 500 maintains an appropriate extension length when it extends. When the practitioner performs semi-permanent makeup, the needle 500 will not over-puncture the skin. The practitioner can also observe whether the needle 500 has punctured too shallowly through the skin layer image on the main body.

[0043] In one embodiment, such as Figure 5 As shown, since the needle 500 needs to be repeatedly inserted into the skin for permanent makeup, and the extension length of the needle 500 also needs to be controlled, the needle 500 needs to protrude from the front end of the pen body while maintaining an appropriate extension length and perform repeated needle piercing actions. Because two movement modes of the needle 500 need to be set, the moving mechanism includes a motion plate 330 to ensure the reciprocating motion of the needle 500 and a ball screw assembly 320 to control the extension length of the needle 500.

[0044] A reciprocating linear motor is mounted on the upper surface of the motion plate 330, and the output shaft of the reciprocating linear motor is fixedly connected to the needle 500 through the connecting block 321. The reciprocating linear motor is used to drive the needle 500 to perform reciprocating motion. The ball screw assembly 320 consists of a screw and ball bearings. The two ends of the screw are fixed in the pen body along the axis of the pen body, and the ball bearings are connected to the motion plate 330 to control the extension length of the needle 500 by controlling the movement of the motion plate 330. The ball screw assembly 320 also includes a lead screw motor, which receives start and stop commands from the host through an electrical control line.

[0045] In yet another embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, most permanent makeup pens currently use a hydraulic pump to inject permanent makeup pigment into the needle 500 of the pen body. This method requires the end of the permanent makeup pen to be connected to a pigment tube. This pigment tube may interfere with the practitioner's work. Therefore, the pen body is designed to consist of a front section 300, a rear section 100, and a middle section 200. The two ends of the middle section 200 are threadedly connected to the front section 300 and the rear section 100, respectively. When in use, the connection between the middle section 200 and the rear section is opened, and a pigment tube that can flow into the needle 500 is placed parallel inside the middle section 200.

[0046] Meanwhile, under this premise, it is also necessary to consider the diversity of permanent makeup pigments and the new pigment colors formed after different pigment ratios. Therefore, multiple small cylinders 210 can be placed in parallel inside the middle cylinder 200, and each small cylinder 210 contains a type of pigment. A mixing cylinder 240 for mixing multiple pigments is also provided. Therefore, a conical mixing cylinder 240 is provided inside the middle cylinder 200. The mixing cylinder 240 is connected to multiple small cylinders 210 and is equipped with a stirring mechanism. The stirring mechanism is used to stir the pigments flowing from multiple small cylinders 210 into the mixing cylinder 240 and push them into the needle 500.

[0047] The stirring mechanism includes: a stirring roller shaft, which consists of a rotor motor and an impeller connected to the motor shaft. A protective cover is also provided on the motor shaft to prevent pigment from contaminating the rotor motor. Since there is an opening at the bottom of the mixing cylinder 240 that communicates with the needle 500, it is also necessary to prevent the mixing cylinder 240 from clogging during the stirring process. Therefore, a lifting frame 250 is also provided at the bottom of the rotor motor. The lifting frame 250 contains an electric telescopic rod 252 for lifting and lowering the stirring roller shaft and a frame 251 to prevent deviation in lifting and lowering displacement.

[0048] Meanwhile, after stirring, it is also necessary to consider that the pigment is viscous and does not flow easily into the needle 500. Therefore, power is needed to pump the pigment into the needle 500. Thus, the stirring mechanism also includes a three-way pipe 260 located at the bottom of the lifting frame 250, which has a first port 261, a second port 263 and a third port 264. The first port 261 is used to collect the pigment passing through the lifting frame 250. The second port 263 is set at an angle greater than 90 degrees to the first port 261. At the same time, a movable piston 262 is provided in the pipe connected to the second port 263. The piston 262 is used to push the pigment to the third port 264. The third port 264 is connected to the needle 500 through an elastic threaded ring 270.

[0049] Finally, since the permanent makeup pen needs to be used on different patients, it is necessary to ensure that the needle 500 is replaced after each use. Therefore, a nut 271 is set on the movement plate 330 at the front end of the corresponding elastic threaded ring 270. The front end of the needle 500 is also provided with a thread that meshes with the nut 271. When using, open the connection between the front section cylinder 300 and the middle section cylinder 200, rotate and remove the original needle 500 on the movement plate 330, insert the new needle 500 into the opening of the front section cylinder 300, and rotate the new needle 500 to replace and install it.

[0050] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, since different proportions of various pigments in paper towels will produce new colors, considering this requirement, multiple spiral push rods 120 are installed in the rear section tube 100 corresponding to multiple small tubes 210. At the same time, a push frame 110 is also provided in the rear section tube 100. The push frame 110 pushes each spiral push rod 120 into the small tube 210. Meanwhile, the rotation of each spiral push rod 120 controls the amount of pigment flowing into the mixing tube 240 from each small tube 210. The front end of each spiral push rod 120 is spiked, and a sealing balloon that can be punctured by the front end of each small tube 210 is placed at the front end.

[0051] The middle section cylinder 200 is also provided with a mounting bracket 220 for placing multiple small cylinders 210 in parallel. The mounting bracket 220 consists of a chuck that holds the small cylinders 210 and a flow plate 230 located at the front end of the small cylinders 210. A plurality of conical blind holes 231 are provided on the flow plate 230 corresponding to the multiple small cylinders 210. Each conical blind hole 231 has a through hole 232 on its side wall. The through hole 232 is used to prevent pigment from clogging.

[0052] When in use, open the connection between the middle section cylinder 200 and the rear section cylinder 100. At this time, the pusher 110 pulls multiple spiral push rods 120 to house them inside the rear section cylinder 100. Each small cylinder 210 also has a tearable film installed at its rear end. Tear off the film of each small cylinder 210 and place it on the mounting frame 220 so that the front end of each small cylinder 210 abuts against the conical blind hole 231 on the flow plate 230. Then reconnect the middle section cylinder 200 and the rear section cylinder 100, and start the pusher 110, which is driven by the electric telescopic rod 252, to push the multiple spiral push rods 120 into the multiple small cylinders 210 and puncture the sealed balloons to reach the conical blind hole 231. Since the spiral outer edge diameter of the spiral push rod 120 is close to the diameter of the small cylinder 210, a certain amount of pigment will flow into the mixing cylinder 240 along the through hole 232 with each rotation of the spiral push rod 120, thereby achieving a precise ratio of each pigment.
