Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a treatment head, treatment hand, and treatment instrument. Background Technology

[0002] Currently, microneedling is widely used in treatments such as underarm odor and facial cosmetic procedures. Microneedling typically involves inserting electrode needles into the skin using a treatment handpiece. Radiofrequency energy is then released to heat the skin or electrically stimulate the skin tissue to achieve the therapeutic goal.

[0003] Because the area of ​​skin that can be inserted with a single microneedle is small, while the area that needs to be treated is large, doctors need to insert the microneedles into different parts of the skin one by one during treatment.

[0004] However, during the treatment process, because doctors need to continuously move the treatment handpiece manually to adjust the position of the electrode needles, this not only increases the doctor's workload and makes the treatment speed relatively slow, making it difficult to meet the needs of efficient treatment, but also the uniformity of treatment is greatly affected by the doctor's technique, making it impossible to guarantee the stability and consistency of treatment. Utility Model Content

[0005] The main purpose of this invention is to provide a treatment head, treatment handpiece, and treatment device, which aims to solve the problems of low treatment efficiency and poor stability and consistency of treatment effects when using existing treatment heads.

The first slider is disposed on the first screw and moves along the second direction under the rotation of the first screw.

[0009] In one embodiment of the present invention, the third driving component includes a mounting bracket, a plurality of third screws and a plurality of third motors, wherein the plurality of third screws extend along the first direction and are spaced apart and arranged in a ring within the mounting cavity; Multiple third motors are installed inside the housing, and the rotation output shaft of each third motor is driven and connected to a third screw. The plurality of the third screws are all drivenly connected to the mounting bracket, and the second driving component and the first driving component are both mounted on the mounting bracket; The third motor drives the third screw to rotate, thereby causing the mounting bracket, the third driving member, the second driving member, and the microneedle to move along the first direction.

[0010] In one embodiment of this utility model, the number of microneedles is 1-4.

[0011] In one embodiment of the present invention, the treatment head further includes a controller, which is connected to the driving component.

[0014] In one embodiment of this utility model, the microneedle is a hollow needle and is connected to an external injection device. The microneedle is used to inject the treatment fluid into the target area.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0025] This utility model proposes a treatment head.

[0026] Combination Figures 1 to 3As shown, in one embodiment of the present invention, the treatment head includes a housing 10, a drive assembly 20, and a microneedle 30; the housing 10 has a mounting cavity 11, and one end of the housing 10 has a treatment window 12 communicating with the mounting cavity 11; the drive assembly 20 is installed in the mounting cavity 11; the microneedle 30 is drivenly connected to the drive assembly 20, the drive assembly 20 drives the microneedle 30 to extend out of the treatment window 12 along a first direction, and the drive assembly 20 drives the microneedle 30 to move in a plane perpendicular to the first direction.

[0027] In this embodiment, the housing 10 is made of medical-grade plastic material and has a rectangular, circular, or other box-like structure, with an installation cavity 11 formed inside. A treatment window 12 is provided at one end of the housing 10. The treatment window 12 is a circular or polygonal opening for the microneedle 30 to extend and contact the skin. Understandably, after the treatment window 12 is in contact with the skin, a vacuum is applied to the installation cavity 11 to create a negative pressure environment. This allows the skin in the treatment area to fit tightly against the treatment window 12 or to form a raised shape, facilitating the insertion of the microneedle 30 into the skin. Furthermore, when multiple microneedles 30 are used, this also improves the consistency of the depth of insertion.

[0028] The drive assembly 20 is installed within the mounting cavity 11 and includes a stepper motor and screw drive mechanism, or a drive mechanism consisting of a motor and a worm gear, or a drive structure consisting of a cylinder and a push rod. The microneedle 30 is connected to the drive assembly 20 via a clamping mechanism or a needle plate. The drive assembly 20 can drive the microneedle 30 to extend out of the treatment window 12 along a first direction (Z-axis direction) to pierce the skin tissue; simultaneously, the drive assembly 20 can also drive the microneedle 30 to move in a plane perpendicular to the first direction (XY plane). Through this drive structure, the treatment head can automatically adjust the position of the microneedle 30, eliminating the need for the doctor to manually move the treatment handpiece, thereby significantly improving treatment efficiency and ensuring uniform coverage of the treatment area, avoiding treatment inconsistencies caused by manual operation.

[0029] In some embodiments, the microneedle 30 described above is used to treat axillary odor. When the microneedle 30 is precisely inserted into the apocrine gland layer under the armpit, the radiofrequency energy released from the tip of the microneedle 30 generates a controllable thermal effect. This heat can efficiently and uniformly coagulate and vaporize the apocrine gland tissue, causing it to permanently deactivate. By driving the microneedle 30 along the first direction to extend the treatment window 12, the microneedle 30 can be inserted into the skin, and then the microneedle 30 is powered on to release radiofrequency energy. After treating one area, the driving component 20 drives the microneedle 30 to be withdrawn from the skin, and then drives the microneedle 30 to move a distance along the left, right, front, or right-hand direction, and then drives the microneedle 30 to extend the treatment window 12 along the first direction, and the microneedle 30 is then inserted into another area of ​​the skin to continue treating other areas.

[0030] Combination Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the driving component 20 includes a first driving member 21, a second driving member 22, and a third driving member 23; The first driving component 21 is drivingly connected to the microneedle 30 and drives the microneedle 30 to move along the second direction, which is perpendicular to the first direction. The second driving component 22 is drivingly connected to the first driving component 21, and drives the first driving component 21 to move the microneedle 30 along a third direction, which is perpendicular to both the first and second directions. The third driving component 23 is connected to the second driving component 22 and drives the second driving component 22 to move the first driving component 21 and the microneedle 30 along the first direction.

[0031] In this embodiment, the first driving component 21, the second driving component 22, and the third driving component 23 are configured to independently control the movement of the microneedle 30 along the second direction, the third direction, and the first direction, respectively, to achieve precise positioning of the microneedle 30 in three-dimensional space. The first driving component 21 and the second driving component 22 work together to move the microneedle 30 along a preset trajectory in the XY plane, such as a straight line, a curve, or a complex pattern; the third driving component 23 controls the insertion depth of the microneedle 30 to ensure consistency in each treatment. Furthermore, the driving components can be connected by components such as mounting plates, couplings, or bearings to reduce transmission errors and vibrations. The driving components can be of the same type or different types of driving structures.

[0032] Combination Figure 3 and Figure 4 As shown, in one embodiment of this utility model, the first driving component 21 includes a first motor 212, a first screw 211, a first slider 213, and a first bearing 214. The first screw 211 extends along a second direction, and the micro needle 30 is mounted on the first slider 213. One end of the first screw 211 is drivenly connected to the first motor 212, and the other end is rotatably connected to the first bearing 214. The first slider 213 is disposed on the first screw 211 and moves along the second direction under the rotation of the first screw 211.

[0033] In this embodiment, the microneedle 30 is mounted on a needle plate, which is mounted on the first slider 213 either via a connecting block or directly. The rotation output shaft of the first motor 212 is rotatably sleeved on the outer periphery of the first screw 211, or rotatably sleeved on the outer periphery of the first screw 211 via a rotating sleeve, and meshes with the first screw 211. When the first motor 212 rotates, the rotation output shaft drives the first screw 211 to rotate. The first bearing 214 is provided with a bearing hole, and the end of the first screw 211 away from the first motor 212 is inserted into the bearing hole and can rotate relative to the first bearing 214, which provides support for the first screw 211. The first slider 213 is mounted on the first screw 211 and is driven to connect with the first screw 211. Specifically, threaded holes with both ends penetrating can be provided on the first slider 213, and the first screw 211 is inserted through the threaded holes to drive the connection between the first screw 211 and the first slider 213. When the first screw 211 rotates under the drive of the first motor 212, the first screw 211 drives the first slider 213 to move the microneedle 30 along the second direction (X-axis). The first screw 211 not only plays a role in cooperating with the first motor 212 to drive the microneedle 30 to move, but also plays a guiding role, so that the microneedle 30 can move accurately along the second direction.

[0034] Combination Figure 3 and Figure 4 As shown, in one embodiment of this utility model, the second driving member 22 includes two second motors 222, two second screws 221, two second sliders 223, and two second bearings 224. One end of each second screw 221 is drivenly connected to a second motor 222, and the other end is rotatably connected to a second bearing 224. Each second slider 223 is disposed on a second bearing 224. Both second screws 221 extend along a third direction. The two ends of the first driving member 21 are respectively connected to the two second sliders 223. The second motors 222 drive the second screws 221 to rotate, so as to drive the second sliders 223, the first driving member 21, and the microneedle 30 to move along a third direction.

[0035] In this embodiment, two second screws 221 are arranged in parallel and extend along a third direction (Y-axis). The two ends of the first drive member 21 are connected to the two second sliders 223 via connecting plates or directly. Simultaneously, the rotation output shaft of the second motor 222 is driven and connected to the second screws 221. The second slider 223 has a similar structure to the first slider 213, and is driven and engaged with the second screws 221 through threaded holes. When the rotation output shaft of the second motor 222 rotates, the second screws 221 can rotate, thereby driving the second sliders 223, the first drive member 21, and the microneedle 30 to move along a third direction.

[0036] The second screw 221 not only works in conjunction with the second motor 222 to drive the first drive component 21 and the microneedle 30, but also acts as a guide, enabling the microneedle 30 to move precisely along a third direction. Through the coordinated control of the first drive component 21 and the second drive component 22, the microneedle moves along the X and Y axes, allowing the treatment head to achieve high-speed, high-precision multi-point treatment and improve treatment efficiency.

[0037] Combination Figure 3 and Figure 4 As shown, in one embodiment of this utility model, the third driving member 23 includes a mounting frame 232, a plurality of third screws 231, and a plurality of third motors 233. The plurality of third screws 231 extend along the first direction and are spaced apart and arranged in a ring within the mounting cavity 11. The plurality of third motors 233 are all installed in the housing 10. The rotation output shaft of each third motor 233 is driven to a third screw 231. The plurality of third screws 231 are driven to the mounting frame 232. The second driving member 22 and the first driving member 21 are all installed on the mounting frame 232. The third motors 233 drive the third screws 231 to rotate, thereby driving the mounting frame 232, the third driving member 23, the second driving member 22, and the micro needle 30 to move along the first direction.

[0038] In this embodiment, the mounting bracket 232 is used to mount the first driving member 21 and the second driving member 22, such as Figure 4 As shown, the mounting bracket 232 includes multiple crossbeams connected end to end and connecting blocks disposed on the crossbeams. The two ends of the second screw 221 are respectively fixed to the connecting blocks. A threaded hole is provided on the mounting bracket 232, through which the third screw 231 passes and is driven to connect with the mounting bracket 232. The rotation output shaft of the third motor 233 is driven to connect with the third screw 231, and by driving the third screw 231 to rotate, the mounting bracket 232 can move along the first direction.

[0039] In one embodiment, threaded holes are provided at each of the four corners of the mounting frame 232. Four third screws 231 and three motors 233 are provided. Each third screw 231 passes through a threaded hole and is driven by a third motor 233. The four third screws 231 are spaced apart and arranged in a ring within the mounting cavity 11. For example, when the cross-section of the mounting cavity 11 is rectangular, the four third screws 231 can be respectively located at the four corners of the mounting cavity 11. The four third motors 233 simultaneously drive the four third screws 231 to rotate, so that the mounting frame 232 drives the third drive member 23, the second drive member 22, and the microneedles 30 to remain horizontal during the movement along the first direction, avoiding or improving the problem of tilting of the mounting frame 232. This allows multiple microneedles 30 to enter the treatment area synchronously and maintain a consistent treatment depth, improving the uniformity of treatment.

[0040] In addition, during treatment, a negative pressure environment needs to be created within the mounting cavity 11 so that the treatment window 12 can tightly cover the surface of the treatment area. In this embodiment, the four third screws 231 are synchronously driven by four third motors 233, so that each microneedle 30 enters the treatment area synchronously, resulting in uniform force on the treatment area. This improves the problem of gaps and air leakage between the housing 10 and the treatment area during microneedle treatment, thus improving the treatment effect. In some specific embodiments, a negative pressure mechanism is also provided on the treatment head, which is connected to the mounting cavity 11 to create negative pressure in the mounting cavity.

[0041] In the above embodiments, the first driving member 21, the second driving member 22, and the third driving member 23 are respectively used to control the movement of the microneedle 30 along the X, Y, and Z directions, that is, the first driving member 21, the second driving member 22, and the third driving member 23 are connected in series to drive the movement of the microneedle 30. In other embodiments, the first driving member 21, the second driving member 22, and the third driving member 23 can also be arranged in parallel so that the first driving member 21, the second driving member 22, and the third driving member 23 jointly drive the microneedle 30 to move in three-dimensional space.

[0042] Combination Figure 2 As shown, in one embodiment of this utility model, the number of microneedles is 1-4.

[0043] In this embodiment, the number of microneedles is 1-4. When there are 2-4 microneedles, each microneedle 30 can be arranged at intervals along the second direction (X-axis), the third direction (Y-axis), or at an angle to the second and third directions. To ensure the uniformity of the treatment effect, the spacing between each microneedle 30 is the same. Each microneedle 30 is mounted on a needle plate and driven by the drive assembly 20 through the needle plate, so that each microneedle 30 can move synchronously. The tip of the microneedle 30 is conical to facilitate skin penetration. The surface of the microneedle 30 is coated with an insulating layer, with only the tip portion conducting electricity to concentrate radiofrequency energy. The arrangement design of multiple microneedles 30 allows the treatment head to treat multiple points simultaneously with a single drive of the microneedles 30, thereby improving treatment efficiency.

[0044] The study found that when multiple microneedles 30 are arranged in double or multiple rows, the excessive number of needles and dense arrangement result in greater skin resistance during needle insertion, making it difficult for the needles to enter the skin. If the needles fail to penetrate the human tissue and discharge onto the skin surface, burns can easily occur. Therefore, multi-row microneedle structures require a larger spacing between the microneedles 30. However, since the heat of the microneedles 30 is centered at the needle tip, a larger spacing can lead to uneven temperature during treatment. Therefore, this application designs the microneedles 30 in a single row. Furthermore, since this application can automatically perform multi-point sequential treatment through the drive component 20, the number of microneedles 30 can be reduced, and the spacing can be made closer, thereby improving the aforementioned problems.

[0045] Combination Figures 5 to 7 As shown, in one embodiment of the present invention, the treatment head further includes a controller, which is connected to the drive component 20. The controller is used to control the drive component 20 to drive the microneedle 30 to move a preset distance in a preset direction according to a preset instruction.

[0046] In this embodiment, the controller can consist of a microcontroller unit (MCU) and corresponding drive circuitry, connected to the drive assembly 20 and various sensors via cables. The controller pre-stores multiple treatment trajectory formulas, including zigzag, S-shaped, loop, and random scanning patterns. The doctor can select appropriate trajectories and parameters (such as X / Y axis step distance, number of treatment points, dwell time, etc.) via buttons on the handle or host software. Based on preset instructions, the controller generates precise pulse signals and sends them to the first drive unit 21, the second drive unit 22, and the third drive unit 23, controlling their rotation angle and speed, thereby driving the microneedle 30 to move a preset distance in a preset direction.

[0047] like Figure 5 As shown, the controller has a preset matrix of M rows and N columns of treatment points, where each coordinate point represents a treatment point. During treatment, the controller first controls the drive component 20 to move the microneedle 30 along the X-axis. After moving to each preset distance, the controller drives the microneedle 30 to move along the Z-axis and insert it into the human tissue to treat the points in the first row and first column of the human tissue. After treatment, the controller drives the microneedle 30 to move along the Z-axis and leave the human tissue, and then drives the microneedle 30 to continue moving along the X-axis to the next treatment point. After treating the treatment points in one row, the controller drives the microneedle 30 to move to the position of the first column in the second row to treat the points in the second row in sequence, thus realizing the above-mentioned Z-shaped trajectory treatment mode.

[0048] like Figure 6 The treatment pattern shown is an S-shaped trajectory. The difference between it and the Z-shaped pattern is that after the treatment of each point in the first row is completed, the controller controls the drive component 20 to drive the microneedle 30 to move along the Y-axis to the position of the last column of the second row, and then the treatment of each point in the second row is completed in sequence along the X-axis.

[0049] like Figure 7 The treatment pattern is a zigzag trajectory. The difference between this pattern and the zigzag pattern is that after the treatment of each point in the first row is completed, the controller controls the drive component 20 to drive the microneedle 30 to move along the Y-axis to the position of the last column of the second row. Then, the treatment of each point in the last column is completed sequentially along the Y-axis, and then the treatment of each point in the last row is completed sequentially along the X-axis.

[0050] In addition, the controller can also incorporate a "random scanning" mode, which includes a recursive block division and random exchange algorithm. This algorithm recursively divides the two-dimensional coordinate array of the treatment area into four sub-blocks, randomly shuffles the order of the sub-blocks, and then recursively performs the same operation on each sub-block until the sub-block size is 1×1. The resulting coordinate sequence ensures that the originally adjacent treatment points are dispersed as much as possible in the new sequence, effectively avoiding the risk of local heat accumulation and thermal damage caused by continuous treatment of adjacent points. This controller achieves full automation and intelligence in the treatment process, greatly reducing reliance on the doctor's operating skills and ensuring a high degree of consistency and repeatability of treatment effects among different patients.

[0051] In one embodiment of the present invention, the treatment head further includes a negative pressure mechanism, which is connected to the mounting cavity 11 and is used to create a negative pressure environment in the mounting cavity 11 when the treatment window 12 is in contact with the treatment area.

[0052] In this embodiment, the negative pressure mechanism includes a negative pressure pump, a negative pressure injector, etc., and is directly connected to the mounting cavity 11 or connected to the mounting cavity 11 through a trachea or pipe. When the treatment window 12 of the treatment head is in contact with the treatment area, the negative pressure mechanism is opened to draw gas from the mounting cavity 11, thereby creating a negative pressure environment within the mounting cavity 11. This causes the skin of the treatment area to fit tightly against the treatment window 12 or to form a raised shape, improving the efficiency of the microneedle 30 penetrating the skin.

[0053] It should be noted that the power of the negative pressure mechanism is adjustable, ensuring that the suction force generated on the skin during negative pressure is greater than the thrust required for the microneedles 30 to penetrate the skin. In some embodiments, the microneedles 30 have a small diameter and a small number, resulting in a small cross-sectional area, which makes it easier to insert them into the skin.

[0054] In some embodiments, the air tube of the negative pressure mechanism is located at the center of the installation cavity. The closer the position is to the center within the treatment window, the more pronounced the negative pressure on the skin. In this case, the power of the negative pressure mechanism is adjusted according to the position of the microneedles within the treatment window. The closer the microneedles are to the center of the treatment window, the lower the power required from the negative pressure mechanism.

[0055] In one embodiment of this utility model, the microneedle 30 is made of conductive material and is electrically connected to an external radio frequency power supply. The microneedle 30 is used to apply radio frequency energy to the target area. Alternatively, the microneedle 30 is a hollow needle connected to an external injection device, and is used to inject the treatment solution into the target area.

[0056] In one embodiment, the microneedle 30 is used for radiofrequency therapy. The microneedle 30 is connected to an external radiofrequency power supply via a wire. After the microneedle 30 is inserted into the skin, it releases radiofrequency energy to heat the tissue for the treatment of axillary odor or skin tightening.

[0057] In another embodiment, the microneedle 30 is used for mesotherapy. The microneedle 30 is a hollow needle and is connected to an external injection device via a flexible tube. The injection device includes a micro-pump and a drug solution container. After the microneedle 30 is inserted into the skin, a treatment solution (such as botulinum toxin or hyaluronic acid) is injected into the target area for cosmetic or drug treatment.
