[0002] Skin disease is a general term for diseases that occur on the skin and skin appendages. The skin is the largest organ in the human body. There are many types of skin diseases, and diseases of various internal organs can also manifest on the skin. There are many causes of skin diseases, and skin lesion examination and sampling is one of the daily tasks of dermatology.

[0003] However, a skin disease lesion sampler is a tool used to collect and take samples of skin lesions from patients with skin diseases; it is often used for skin disease diagnosis and pathological examination, helping doctors determine the nature and cause of the lesions.

[0004] For example, patent number CN118766514A discloses a skin disease lesion sampler and its use method. When in use, the device can effectively improve the visual brightness of the sampling area, thereby improving the observation effect; at the same time, it can have the function of auxiliary clamping, and can blow away some of the detached skin flakes, making it easier to clamp and fix them, thereby facilitating sampling.

[0005] However, in the actual application of the above patent for sampling skin flakes, the structure is complicated. The blowing and clamping of the skin flakes that have fallen off the edges need to be performed in multiple times, resulting in the skin flakes still being in a blowing state after clamping. The blowing needs to be turned off manually. If the blowing is not turned off in time, the clamped and sampled skin flakes are easily blown away. For this reason, we provide a skin lesion sampling structure to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, the structure of the prior art is complicated, and the blowing and clamping of skin flakes that have fallen off the edges need to be performed in batches, resulting in the skin flakes still being in a blowing state after clamping, and the blowing needs to be manually turned off. If the blowing is not turned off in time, the skin flakes clamped for sampling are easily blown away. For this reason, the present embodiment provides a skin lesion sampling structure, which can perform synchronous blowing during the clamping process of the skin flakes, and blow the skin flakes that have fallen off the edges until they are lifted up, which is convenient for clamping and sampling, and the blowing can be automatically turned off after the skin flakes are clamped, to avoid blowing off the skin flakes after clamping and sampling.

[0023] See also Figure 1 - Figure 6 The present embodiment proposes a skin lesion sampling structure, including a main board 1, an upper surface of the main board 1 is provided with a mounting groove 2, and a magnifying glass 3 installed in a reserved hole on the upper surface of the main board 1 through the mounting groove 2, and a sampling mechanism 4 is provided on the bottom surface of the main board 1. The sampling mechanism 4 includes two clamping plates 401 located on the bottom surface of the main board 1, and a detachable clamping blade 402 connected to the outer end of the clamping plate 401 and located at the lower part of the magnifying glass 3, and the clamping blade 402 is used to clamp and remove skin flakes.

[0024] refer to Figures 1 to 6The setting of the clamping blade 402 can be easily installed or disassembled at the clamping plate 401, so that the clamping blade 402 can be replaced and disassembled for disinfection and cleaning after the two clamping blades 402 clamp and sample the skin flakes. In addition, the setting of the magnifying glass 3, the edge of the magnifying glass 3 can be provided with a fill light or other lighting components, which is convenient for providing lighting when sampling skin flakes.

[0025] A transparent guide ring 5 is provided on the bottom surface of the magnifying glass 3, and the transparent guide ring 5 is used to locate the center position of the magnifying glass 3. By providing the transparent guide ring 5, it is convenient for medical staff to observe the central area of ​​the magnifying glass 3, so as to provide guidance when clamping skin flakes. The magnification clarity of the center of the magnifying glass 3 is higher than that of the edge, so that the medical staff can clamp the skin flakes for sampling at the central area of ​​the magnifying glass 3 and the clamping position of the clamping blade 402.

[0026] As a supplement, the provision of the transparent guide ring 5 can facilitate medical personnel to operate the clamping plate 401 to accurately clamp the skin flakes, thereby avoiding the situation where the skin flakes sample falls due to clamping deviation.

[0027] Two mounting rods 6 are installed on the outer surface of the main board 1 through pin shafts, and the outer ends of the mounting rods 6 are fixedly connected to mounting plates 7, and controllers 8 are installed on the upper surfaces of the two mounting plates 7. By setting the mounting rods 6, it is convenient for medical staff to hold the entire device for use, and by setting the two mounting rods 6, it is convenient for medical staff to hold the entire device with both hands, reducing the impact of deviation and shaking when holding with one hand on the clamping and sampling of skin flakes, thereby improving the accuracy of clamping.

[0028] As a supplement, the setting of the controller 8 can facilitate the control and startup of the entire device. Both controllers 8 can control the startup of the drive components, and the controller 8 adopts a PLC programmable logic controller, such as Siemens S7-1200 series or Mitsubishi FX3U series. The specific model is selected according to actual needs. The controller has powerful data processing capabilities and multiple input and output interfaces, and is suitable for complex industrial control environments.

[0029] The outer end of the mounting rod 6 is fixedly connected with a handle 9. By providing the handle 9, it is convenient for medical personnel to hold the entire device for use, and the outer surface of the handle 9 is provided with anti-slip grooves, which can improve the stability of medical personnel when holding it and reduce the possibility of slipping.

[0030] The sampling mechanism 4 also includes a driving assembly and a blowing assembly connected to the clamping plate 401 . The driving assembly is used to drive the blowing assembly to blow air to the skin flakes and drive the clamping blade 402 to clamp and sample the skin flakes.

[0031] refer to Figures 1 to 6The drive assembly is configured to drive the two clamping blades 402 to move closer to or away from each other, so that the clamping blades 402 can clamp and sample skin flakes, and at the same time drive the blowing assembly to blow air to the skin flakes with raised edges, thereby providing the clamping blades 402 with the convenience of clamping and sampling skin flakes.

[0032] The drive assembly includes a dual-output shaft motor 403 installed in a reserved groove on the bottom surface of the main board 1, and the two output shafts of the dual-output shaft motor 403 are fixedly connected to a screw rod 404. The drive assembly also includes a wire seat 405 fixedly connected to the outer end of the clamping plate 401 and threadedly matched with the screw rod 404.

[0033] By providing a driving assembly, the two clamping plates 401 can be easily driven to move closer to or farther from each other, so that the clamping plates 401 can drive the clamping blades 402 to clamp or release the skin flakes, thereby sampling the skin flakes in the infected area of ​​the skin disease patient.

[0034] By starting the dual-output shaft motor 403, the two output shafts of the dual-output shaft motor 403 respectively drive the two screw rods 404 to rotate, and the thread directions of the two screw rods 404 are opposite, so that when the screw rods 404 and the wire holder 405 are threadedly matched, the two wire holders 405 are driven to move closer to or away from each other, so that the wire holder 405 drives the clamping plate 401 and the clamping blade 402 to clamp and sample the skin flakes.

[0035] The sampling mechanism 4 also includes a protective plate 406 fixed to the inner wall of the reserved groove on the bottom surface of the main board 1, and the bottom surface of the protective plate 406 is provided with a guide groove 407 that slides with the wire seat 405. By setting the protective plate 406, the dual-output shaft motor 403 can be easily protected, and through the guide groove 407, the wire seat 405 can be limited and guided during the movement, so as to facilitate the improvement of the stability of the wire seat 405 in driving the clamping plate 401 and the clamping blade 402 to clamp the skin flakes.

[0036] During the movement of the wire seat 405 at the screw rod 404, the wire seat 405 can be limited and guided by the guide groove 407, so that the wire seat 405 can move stably under the guidance of the guide groove 407, reducing the shaking of the wire seat 405 during the movement at the screw rod 404, thereby improving the effect of the clamping blade 402 on clamping skin flakes.

[0037] The blowing assembly includes a fixed cylinder 408 fixed on the outer surface of the clamping plate 401, and a ventilation tube 409 sleeved inside the fixed cylinder 408. The outer end of the ventilation tube 409 is equipped with a one-way air outlet valve 4010 located outside the clamping blade 402. The one-way air outlet valve 4010 is used to blow up the skin flakes.

[0038] By setting up an air blowing component and the setting of a fixed cylinder 408 in the air blowing component, it is possible to limit and stabilize the ventilation tube 409, and the transmission of gas in the ventilation tube 409 can enable the one-way air outlet valve 4010 to spray the gas, so that the one-way air outlet valve 4010 can spray the gas to the patient's skin flakes, and blow up the skin flakes that have detached from the edge.

[0039] In addition, the one-way air outlet valve 4010 can only spray out gas and will not draw air from the outside, and the one-way air outlet valve 4010 is located on the outside of the clamping blade 402, which can facilitate blowing along with the clamping blade 402 when clamping and sampling the patient's skin flakes.

[0040] The blowing assembly also includes a compression frame 4012 fixed to the bottom surface of the main board 1 and connected to the ventilation pipe 409. The blowing assembly also includes an extrusion plate 4011 fixedly connected to the clamping plate 401 and connected to the compression frame 4012. The extrusion plate 4011 is used to extrude and exhaust the compression frame 4012 through the clamping plate 401.

[0041] By setting up an air blowing component and the setting of the extrusion plate 4011 in the air blowing component, it is convenient to squeeze the compression frame 4012, so that the gas in the compression frame 4012 is transmitted to the one-way air outlet valve 4010 through the ventilation pipe 409, and the gas is sprayed out by the one-way air outlet valve 4010, so that the skin flakes can be blown up.

[0042] In addition, the middle section of the compression frame 4012 is fixedly connected to the main board 1, and the two ends of the compression frame 4012 are not contracted, so that when the two ends of the compression frame 4012 are squeezed, the gas in the compression frame 4012 can be transmitted to the ventilation pipe 409.

[0043] The blowing assembly also includes a one-way air intake valve 4013 installed at the air inlet of the compression frame 4012, and a limiting plate 4014 fixed to the outer surface of the clamping plate 401 and sleeved on the outer surface of the ventilation pipe 409. By setting the one-way air intake valve 4013, one-way inflation of the compression frame 4012 can be facilitated, thereby preventing the gas in the compression frame 4012 from being discharged from the one-way air intake valve 4013 when being squeezed.

[0044] The setting of the limiting plate 4014 can facilitate the limiting and stabilization of the edge of the ventilation tube 409 and the one-way air outlet valve 4010, thereby preventing the one-way air outlet valve 4010 from shaking when blowing air to the skin flakes.

[0045] Working principle: When taking skin lesion samples from the infected area of ​​a skin disease patient, the medical staff first controls the start-up of the dual-output shaft motor 403 through the controller 8, so that the two output shafts of the dual-output shaft motor 403 drive the two screw rods 404 to rotate forward, so that the screw rods 404 and the wire seat 405 are threadedly matched to drive the clamping plate 401 to continue to twist and move under the limiting action of the guide groove 407, and the thread directions of the two screw rods 404 are opposite, so that the two wire seats 405 and the two clamping plates 401 can be driven to move away from each other, and then the two clamping blades 402 can be unfolded.

[0046] When the clamping blade 402 is unfolded, the extrusion plate 4011 pulls the compression frame 4012 to exhaust the external air through the one-way air inlet valve 4013, so that the compression frame 4012 is stretched out. At this time, the overall device is held by the handle 9, and the magnifying glass 3 and the transparent guide ring 5 are moved above the infected area of ​​the patient's skin. The two unfolded clamping blades 402 are located in the area of ​​skin flakes that need to be sampled, and the controller 8 can control the reverse rotation of the screw rod 404 again, so that the two clamping blades 402 clamp the skin flakes for sampling.

[0047] And when clamping and sampling, the compression frame 4012 can be squeezed by the extrusion plate 4011, so that the gas in the compression frame 4012 is transmitted to the one-way air outlet valve 4010 through the ventilation pipe 409, and the gas is sprayed out by the one-way air outlet valve 4010, thereby blowing up the skin flakes detached from the edge, thereby facilitating the clamping and sampling of the clamping blade 402.
