[0050] As described above, the existing follicle extraction device applied to the end of the robot generally targets one-way rotation application and cannot avoid damage to the hair shaft when the needle pierces the follicle unit. In addition, due to the reasons of large occupied space, low integration, etc., the existing follicle extraction device is easy to press the patient during the robot execution, and the positioning accuracy of the robot will also be affected under the condition of a large load of 4-5 kg. At the same time, the existing follicle extraction device does not have a protection device for the vision system, which is easy to be disturbed by foreign matter or liquid during the robot operation, thereby causing false recognition and even medical accidents.

[0051] In order to overcome the above-mentioned defects existing in the prior art, the present application provides a hair follicle extraction device, which can drive the puncture needle to reciprocate by setting a rotary drive mechanism, so as to realize hair follicle extraction without shaving, and can realize miniaturization and easy operation of the hair follicle extraction by integrating the puncture mechanism with an integrated visual system.

The axial drive mechanism 13 is used to drive the puncture needle 112 to axially translate to a rated distance (for example, 30 mm) from the extraction object via the transmission shaft core 111. The rotary drive mechanism 14 is used to drive the puncture needle 112 to reciprocate around the shaft after the puncture needle 112 pierces the scalp of the extraction object, so as to extract the corresponding hair follicle.

[0054] In addition, in the embodiments shown in FIGS. 1 and 2, the second end of the transmission shaft core 111 is provided with an electromagnetic brake 113, which is used to allow the axial drive mechanism 13 to drive the puncture mechanism 12 to axially translate when power is supplied, and to hold the transmission shaft core 111 when power is lost. In this way, the electromagnetic brake 113 can prevent the puncture mechanism 12 from freely falling due to inertia after the axial drive mechanism 13 loses power.

The camera unit is used to sequentially acquire follicle images of a plurality of to-be-observed regions of the illuminated object under the short-distance uniform illumination of the light source assembly.

[0081] Further, the rack 11 optionally comprises a first mounting portion 114 and a second mounting portion 115. The imaging assembly comprises a left-eye camera unit 171, a right-eye camera unit 172, a light source connector 173, and a synchronous trigger protection board 174. Here, the left-eye camera unit 171 is connected to the first mounting portion 114 to collect the hair follicle images of the first region corresponding to the extraction object. The right-eye camera unit 172 is connected to the second mounting portion 115 to collect the hair follicle images of the second region corresponding to the extraction object. The light source connector 173 is used to fixedly connect the light source assembly. The synchronous trigger protection board 174 is connected to the left-eye camera unit 171 via a first trigger connector 1741 and connected to the right-eye camera unit 172 via a second trigger connector 1742, and is used to send a synchronous trigger signal to the left-eye camera unit 171 and the right-eye camera unit 172 at the same time to control the two to collect the hair follicle images of the corresponding regions at the same time.

[0082] Please further refer to FIG. 17, which shows a connection diagram of the lens and the camera according to some embodiments of the present application.

[0083] As shown in FIG. 17, the light source connector 173 comprises two lenses, and the limiting protrusions comprise the lens steps of the outer circle of the top of the lens. Here, the first lens is connected to the second threaded structure on the top of the left-eye camera unit 171 through the first threaded structure on the bottom of the lens, and is connected to the corresponding first light source assembly through the first lens step to provide short-distance uniform illumination to the first image collection region of the left-eye camera unit 171.

[0084] In this way, the integrated visual system can integrate the light source assembly and the imaging assembly in a coaxial arrangement, thereby meeting the structural requirements of miniaturization, lightness, high stability, and short-distance uniform illumination, and realizing large-angle (e.g., 0°-30°) observation of the binocular camera in the imaging assembly at a preset optical center distance (e.g., 80 mm) to avoid interference of the binocular camera.

[0085] Those skilled in the art can understand that the coaxial arrangement shown in FIG. 16 is only some non-limiting embodiments provided by the present application, which is intended to clearly show the main idea of the present application and provide some specific schemes for the public to implement, rather than to limit the protection scope of the present application.

[0086] Optionally, in some other embodiments, the present application also has a non-coaxial arrangement. Please refer to FIG. 18, which shows a structural diagram of an integrated visual system according to some embodiments of the present application.

[0087] In the embodiment shown in FIG. 18, the light source connector is optionally disposed between the first mounting portion 114 and the second mounting portion 115 and connects the corresponding third light source assembly through the limiting protrusion to simultaneously provide short-distance uniform illumination to the image capture areas of the left-eye camera unit 171 and the right-eye camera unit 172.

[0088] In this way, the integrated visual system can integrate the light source assembly and the imaging assembly in a non-coaxial arrangement. Since the end size of the left-eye camera unit 171 and the right-eye camera unit 172 is smaller than the root size, the collision of the front lenses of the binocular camera can be avoided, thereby supporting a larger included angle (e.g., 0°-70°) observation of the binocular camera at a preset optical center distance (e.g., 80 mm) to avoid interference of the binocular camera.

[0093] In addition, in some embodiments, the light source assembly described above also optionally includes a clamping hoop 165. The outer side of each clamping member is respectively provided with a clamping hoop placement slot 1615, and after the clamping hoop 165 is placed in the inner side of each clamping member 1614 and fixedly connected with each clamping step 1613, the outer side of each clamping member 1614 is locked through the clamping hoop placement slot of the clamping hoop 165 to prevent the clamping stopper from coming out of the clamping step 1613.

[0094] In addition, in the embodiment shown in FIG. 21, the lamp plate 162 is optionally provided with a first power series socket 1622, at least one second power series socket 1623 and a current limiting resistor 1624. Here, the first power series socket 1622 is connected to an external power source, and at least one second power series socket 1623 is connected to the first power series socket 1622 to supply power to each lamp bead 163.

[0100] In addition, in some embodiments, the first number of lamp bead positioning steps have different step angles and different centrifugal radii, and the lamp bead positioning steps of each step angle are staggered and spaced at each centrifugal radius, so as to adjust the value of the second number and the mounting position of each lamp bead 163 on the mounting rack 11 according to the target brightness distribution of the illumination object. In addition, the staggered and spaced lamp bead positioning steps 112 of each step angle can make the layout of the lamp beads 14 on the mounting rack 11 compact, so as to realize the miniaturization design of the light source assembly.

[0101] In addition, in some embodiments, the first number of lamp bead positioning steps 1612 have different step angles and different centrifugal radii, and the lamp bead positioning steps 1612 of each step angle are staggered and spaced at each centrifugal radius, so as to adjust the value of the second number and the mounting position of each lamp bead 163 on the mounting rack 161 according to the target brightness distribution of the illumination object.

[0102] Please further refer to FIG. 24A and FIG. 24B, FIG. 24A shows a schematic diagram of the lighting condition of a lamp bead lighting area according to some embodiments of the present application. FIG. 24B shows a schematic diagram of the lighting condition of a lamp bead lighting area according to some embodiments of the present application.

[0103] As shown in FIG. 24A, the plurality of focus points are distributed in a ring shape in the illumination area of the illumination object, and at least one main lamp bead 141 is installed at each of the plurality of focus points to control the brightness of the illumination area to the expected brightness.

[0104] Further, in some embodiments, the light source assembly can adjust the power of the lamp beads 14 to adjust the illumination of the lamp bead illumination area. Here, the second number of lamp beads 14 are divided into main lamp beads 141 and auxiliary lamp beads 142. One main lamp bead 141 with a first power is installed at each of the plurality of focus points to control the brightness of the illumination area to the expected brightness. And at least one auxiliary lamp bead 142 with a second power is installed between each of the plurality of focus points to adjust the brightness uniformity of the illumination area.

[0105] As shown in FIG. 24B, the light source assembly can adjust the number of lamp beads 14 to adjust the illumination of the lamp bead illumination area. Here, the second number of lamp beads 14 are divided into main lamp beads 141 and auxiliary lamp beads 142. The plurality of focus points of the illumination area of the illumination object are distributed in a rectangular shape in the illumination area, and at least one main lamp bead 141 is installed at each of the plurality of focus points to control the brightness of the illumination area to the expected brightness. And at least one auxiliary lamp bead 142 is installed between each of the plurality of focus points to adjust the brightness uniformity of the illumination area.

[0106] Specifically, the lamp bead array formed by the lamp beads 163, and the layout of the main lamp beads 1631 and the auxiliary lamp beads 1632 can be calculated according to the illumination brightness and uniformity requirements in the actual application scenario. For example, the to-be-illuminated area of the illumination object is a rectangular area of 80*120mm, and it can be calculated that the light source assembly needs to provide a light intensity of 5000lx with a fluctuation range of within 10%. Then, based on the illumination and rated voltage requirements, it can be calculated that 6 main lamp beads 1631 with a rated voltage of 2.9V and a rated current of 20mA are needed to provide 4000K white light to illuminate the illumination area to control the brightness of the illumination area to 5000lx.

[0107] In addition, according to the irradiation angle (for example: 25°) of the lamp beads and the corresponding light intensity-angle curve, the brightness distribution of the focal point at the working distance (for example: 200mm) can be simulated in the design software or the image editing software with superimposed colors. At this time, as shown in FIGS. 24A and 24B, the focal point is usually a circular spot, with the center being the brightest and the periphery gradually weakening. Then, the focal point can be arranged in the shape of the outer contour of the illumination area, and can be adjusted through the illumination distribution displayed by the design software. At this time, the cumulative light intensity when the spots overlap can be simulated, and the number of secondary lamp beads 1632 irradiated at the corresponding spot position can be simulated by adjusting the weight of each spot. During the layout process, the position of the focal point can be adjusted first, and then the number of primary lamp beads 1631 in relatively dark places can be considered to increase the brightness of the illumination area.

[0108] Then, after arranging the corresponding number of primary lamp beads 1631 and secondary lamp beads 1632, the axial direction of each lamp bead can be constrained to be collinear with the focal point to determine the orientation of each lamp bead, and then the step angle of the lamp bead positioning step 1613 can be calculated using Boolean operation or other equivalent methods to complete the design of the mounting frame 161.
