Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1:
[0031] like Figure 1-6 As shown, this embodiment of the invention provides a dermatological scraping device, including a handle 3, a connecting structure 2 at the upper end of the handle 3, and a scraping structure 1 at the upper end of the connecting structure 2.
[0032] The scraping structure 1 includes a first connecting frame 104. A through groove 101 is provided at the center of the front side wall of the first connecting frame 104 near its upper and lower edges. A blade 102 is disposed inside each of the two through grooves 101, with both ends of the blade 102 fixedly connected to the inner side walls of the two through grooves 101. A sliding groove 107 is provided on the rear side wall of the first connecting frame 104 at the lower end of the two through grooves 101. A sample collection plate 109 is slidably connected inside each of the two sliding grooves 107. The lower ends of the centers of the two side walls of the first connecting frame 104 are respectively provided with... The sample collection plate 109 is equipped with an adjustment structure. By setting the angle between the blade 102 and the through groove 101 at 20 degrees, the skin surface at the sampling location can be scraped, and the tissue on the skin surface can be collected. The scraped skin tissue enters the rear end of the blade 102 through groove 101 at the lower end of the blade 102 and is collected inside the sample collection plate 109. When sampling, the sample collection plate 109 can be pulled out from the inside of the slide groove 107. The sample collection plate 109 is L-shaped, which makes the overall sampling more convenient and less likely to cause sample loss.
[0033] The adjustment structure includes a connecting shaft 111. One end of the connecting shaft 111 is fixedly connected to the side wall of the first connecting frame 104. A torsion spring 110 is fixedly connected to the side wall of the connecting shaft 111. A sleeve 106 is provided outside the torsion spring 110. The other end of the connecting shaft 111 is rotatably connected to an inner side wall of the sleeve 106. The other end of the torsion spring 110 is fixedly connected to an inner side wall of the sleeve 106. A connecting plate 105 is fixedly connected to one side wall of the sleeve 106. A slider 108 is fixedly connected to the center of the other side wall of the connecting plate 105. When the front side wall of the first connecting frame contacts the skin surface, the angle of the first connecting frame is adjusted by the cooperation of the connecting shafts 111 and the torsion spring 110 on both sides, which are rotatably connected inside the two sleeves 106. In addition, according to the characteristics of the torsion spring 110, a certain holding force can also be provided to achieve better collection of tissue on the skin surface.
[0034] The connecting structure 2 includes a second connecting frame 205. The upper surfaces of the two sides of the second connecting frame 205 are respectively provided with first connecting grooves 202. The other inner side walls of the two first connecting grooves 202 are respectively provided with second connecting grooves 203. Adjusting knobs 201 are respectively provided at the upper ends of the center of the two side walls of the second connecting frame 205. The other ends of the two adjusting knobs 201 pass through the two side walls of the second connecting frame 205 and respectively lead to the interior of the two first connecting grooves 202. The ends are respectively movably connected to connecting slide plates 208.
[0035] The second connecting bracket 205 has a storage groove 204 at the center of its upper surface near the middle. A placement hole 209 is located at the center of the inner front wall of the storage groove 204. A spring 210 is installed inside the placement hole 209. The front end of the spring 210 is fixedly connected to the inner front wall of the placement hole 209, and the rear end of the spring 210 is fixedly connected to a top bead 207. In use, by sliding the two sliders 108 into the interiors of the two connecting slide plates 208, and by turning the adjustment knobs 201, the connecting slide plates 208 are pulled to both sides. This ensures the stability of the first connecting bracket 104 after connection and allows for quick disassembly and installation. Furthermore, the first connecting bracket 104 can be adjusted to a vertical position and placed inside the storage groove 204. Before adjustment, the two connecting slide plates 208 are released from their restriction on the two sliders 108, allowing them to slide up and down. The top bead 207, in conjunction with the semi-circular hole 103, restricts and stores the first connecting bracket 104 inside the storage groove 204 for easy storage.
[0036] A semi-circular hole 103 is provided at the lower end of the center of the front side wall of the first connecting frame 104. A connecting bolt 206 is fixedly connected at the center of the lower end face of the second connecting frame 205. The lower end of the connecting bolt 206 passes through the upper end face of the handle 3 and leads to the interior. It is threadedly connected to the handle 3, which allows it to be disassembled and carried or placed. The split structure can reduce the space occupied.
[0037] The included angle between the two blades 102 and the two through slots 101 is 20 degrees, which facilitates the scraping and collection of the patient's surface skin tissue. The surface of the handle 3 is covered with rubber, providing a good grip for the user's hand.
[0038] Working principle: This application is a dermatological scraping device. When in use, the angle between the blade 102 and the through groove 101 is 20 degrees, which can scrape the skin surface at the sampling location and collect the skin tissue. The scraped skin tissue enters the rear end of the blade 102 through groove 101 and is collected inside the sample collection plate 109. When sampling, the sample collection plate 109 can be pulled out from the inside of the slide groove 107. The sample collection plate 109 is L-shaped, which makes the overall sampling more convenient and less likely to cause sample loss.
[0039] When the first connecting frame contacts the skin surface through the front side wall, the angle of the first connecting frame is adjusted by the cooperation of the connecting shafts 111 on both sides and the torsion springs 110 inside the two sleeves 106. In addition, according to the characteristics of the torsion springs 110, a certain holding force can be provided to achieve better collection of tissue on the skin surface.
[0040] By sliding the two sliders 108 into the interiors of the two connecting slide plates 208 respectively, and by turning the adjustment knobs 201 respectively, the connecting slide plates 208 are pulled to both sides, thereby ensuring the stability of the first connecting frame 104 after connection, and achieving the effect of quick disassembly and installation. Furthermore, the first connecting frame 104 can be adjusted to a vertical position and placed inside the storage slot 204. By using the top bead 207 and the semi-circular hole 103 to cooperate, the first connecting frame 104 is restricted and stored inside the storage slot 204 for easy storage.
[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
