[0032] Tuberculous pus has special physical properties, which is often more thick and contains a large number of necrotic tissue, inflammatory cells and other components. During the sample extraction process, these substances are prone to block the internal passage of the needle tube, causing the resistance encountered during manual extraction to increase sharply. In the face of this dilemma, medical staff will generally use such as adjusting the extraction force, dredging the needle tube and other relief measures. However, these operations are prone to cause the displacement of the needle. Once the displacement occurs, on the one hand, it will interfere with the accurate position of the puncture needle in the spine, and on the other hand, it may cause the puncture to fail, ultimately interfering with the inspection and analysis of the pus sample and the subsequent treatment process.

[0033] Embodiment, refer to Figure 1 As shown in the figure, the device comprises a puncture device body 1, the puncture device body 1 comprises a pumping mechanism 11 and a needle assembly 12, the pumping mechanism 11 comprises a puncture tube body 111, the inside of the puncture tube body 111 is sealingly provided with a sealing extraction rod 112, the end of the sealing extraction rod 112 away from the puncture tube body 111 is fixedly installed with a top block 113, the end of the puncture tube body 111 close to the top block 113 is provided with a limiting assembly 4, the other end of the limiting assembly 4 is connected with the outer wall of the sealing extraction rod 112, and the limiting assembly 4 is used for assisting in limiting the sealing extraction rod 112.

[0034] The needle assembly 12 comprises an auxiliary mounting tube 121, the auxiliary mounting tube 121 is located at the end of the puncture tube body 111 away from the top block 113, the inside of the auxiliary mounting tube 121 is provided with a needle body 122, and the outer wall of the auxiliary mounting tube 121 is provided with a limiting tube 123. The inside of the needle body 122 is provided with a dredging assembly 2 for assisting in extracting pus.

[0035] First, the specific structure of the dredging assembly 2 is disclosed, the dredging assembly 2 comprises a plurality of inner holes 22 opened in the inside of the needle body 122, the inside of each of the plurality of inner holes 22 is rotatably provided with a dredging blade 21, and the plurality of inner holes 22 and the plurality of dredging blades 21 are arranged at the end of the needle body 122 close to the auxiliary mounting tube 121.

[0036] Refer to Figure 2 and combine Figure 3As shown, the needle body 122 is provided with a plurality of inner holes 22 near one end of the auxiliary mounting tube 121, and each inner hole 22 is equipped with a rotatable dredging blade 21. During the extraction of pus, when the pus flows through the position where the dredging blade 21 is located, the blade can cut and crush the coagulum or larger particles in the pus due to the specific position layout of the blade, thereby realizing the crushing function of the pus and reducing the blockage caused by large coagulum in the pus.

[0037] At the same time, with the extraction flow of pus in the needle body 122, such flow will generate a force on the dredging blade 21, such as Figure 4 and Figure 5 As shown, based on the principle of mechanics, the force causes the dredging blade 21 to rotate around the shaft, and the rotation of the blade changes the original flow direction and speed distribution of the pus, forming a flow guiding effect, so that the pus can be more smoothly extracted through the needle body 122, effectively reducing the blockage during the entire pus extraction process, and effectively ensuring the efficient and smooth progress of the extraction operation.

[0038] Secondly, the specific structure of the limiting tube 123 is disclosed. The limiting tube 123 includes a fixed mounting ring 32 fixedly installed on the surface of the puncture tube body 111 end portion. The fixed mounting ring 32 is sleeved on the surface of the auxiliary mounting tube 121, and the inside of the fixed mounting ring 32 is screw-mounted with a transparent tube body 31.

[0039] When extracting pus, the depth of insertion is extremely critical. If the needle body 122 is inserted too shallowly, it is difficult to access and extract pus, and the remaining pus will accumulate and solidify in the subsequent process, thereby causing blockage of the extraction pipeline. When inserted too deeply, it may pierce the surrounding tissue or blood vessels, causing blood and other impurities to mix with the pus, which will significantly increase the viscosity and complexity of the pus, and also easily cause blockage. In view of this, as shown in Figure 1 As shown, the puncture tube body 111 end portion is fixedly provided with a fixed mounting ring 32, and the inside of the fixed mounting ring 32 is rotatably provided with a transparent tube body 31. Since the fixed mounting ring 32 is sleeved on the surface of the auxiliary mounting tube 121, the transparent tube body 31 is also sleeved on the outside of the auxiliary mounting tube 121 and the needle body 122, and the transparent tube body 31 can be replaced according to different extraction positions. When performing the needle extraction operation, the transparent tube body 31 is attached to the skin of the extraction site, thereby accurately determining the insertion size of the needle body 122, thereby effectively avoiding problems caused by shallow or deep insertion, reducing the occurrence of blockage during the pus extraction process, and ensuring the smooth progress of the extraction work.

[0040] Then the specific structure of the limiting component 4 is disclosed, the limiting component 4 includes a top cover 42 clamped and installed at the open end of the puncture pipe body 111, a sealing extraction rod 112 slides in the inside of the top cover 42, the sealing extraction rod 112 is fixedly installed with a mounting plate 41 on the outer wall of the side close to the top block 113, the surface of the mounting plate 41 is fixedly installed with two limiting plates 44, two cavities 43 are opened in the inside of the top cover 42, and the outer wall of the limiting plate 44 is attached to the inner wall of the cavity 43.

[0041] In combination Figure 6 As shown, the open end of the puncture pipe body 111 is clamped with the top cover 42 (the top cover 42 can be connected with the outer wall of the puncture pipe body 111 through threads, not shown in the figure), and the sealing extraction rod 112 can slide in the inside of the top cover 42 during the extraction process. When the pus extraction operation is performed and the sealing extraction rod 112 is pulled to apply extraction pressure to the pus, the sliding of the sealing extraction rod 112 drives the sliding of the mounting plate 41, and the sliding of the mounting plate 41 can drive the synchronous sliding of the limiting plate 44 fixed on the surface of the mounting plate 41 in the cavity 43 of the top cover 42. Through the cooperation between the limiting plate 44 and the cavity 43, the extraction stroke and range of the sealing extraction rod 112 can be accurately limited, and the entire pus extraction process can be accurately and stably performed according to the set requirements.

[0042] In order to further improve the fit between the transparent pipe body 31 and the skin during the needle insertion process, by Figure 1 As shown, the end of the transparent pipe body 31 away from the fixed mounting ring 32 is provided with a suction pad 5.

[0043] The improvement lies in that the end of the transparent pipe body 31 away from the fixed mounting ring 32 is additionally provided with a suction pad 5 (preferably made of silica gel), which can tightly adhere to the skin surface by using its suction property, effectively filling the possible small gap between the transparent pipe body 31 and the skin, thereby further stabilizing the fit state of the transparent pipe body 31 and the skin. In this way, not only can the penetration size of the needle body 122 be more accurately determined, but also a stable operation environment can be maintained during the entire extraction process, reducing the interference of external factors on the extraction process, thereby facilitating the reduction of pus extraction blockage and improving the accuracy and reliability of the extraction operation.

[0044] In order to better guide and break the pus, by Figure 3 As shown, the side of the dredging blade 21 away from the inner hole 22 is helical.

[0045] The improvement lies in: from the perspective of breaking, the spiral-shaped dredging blade 21 can interact with the condensate and larger particles in the pus in a more complex way compared to the linear-shaped dredging blade 21. When the particles in the pus contact the spiral-shaped dredging blade 21, the spiral edge of the dredging blade 21 can cut, squeeze and chop the particles from multiple angles and directions, enhancing the breaking effect of the pus and more effectively reducing large particles or condensate that can cause blockage; from the perspective of flow guiding, the spiral-shaped design can guide the pus to flow along a specific spiral path. When the pus passes through the spiral-shaped dredging blade 21, its flow direction is changed, allowing the pus to flow more orderly inside the needle body 122, reducing the occurrence of disordered turbulent flow state that can cause blockage.

[0046] As shown above, the working principle of the present scheme is as follows: first, the puncture pipe body 111 is fixed with a fixed mounting ring 32, and a transparent pipe body 31 is rotatably arranged inside the fixed mounting ring 32. Since the fixed mounting ring 32 is sleeved on the surface of the auxiliary mounting pipe 121, the transparent pipe body 31 is also sleeved outside the auxiliary mounting pipe 121 and the needle body 122, and the transparent pipe body 31 can be replaced according to different extraction positions. When the needle extraction operation is performed, the transparent pipe body 31 is attached to the skin of the extraction site, which can accurately determine the penetration size of the needle body 122, thereby effectively avoiding problems caused by too shallow or too deep penetration;

[0047] When the pus extraction operation is performed, the sealing extraction rod 112 is pulled to apply extraction pressure to the pus, the sliding of the sealing extraction rod 112 drives the sliding of the mounting plate 41, and the sliding of the mounting plate 41 can drive the synchronous sliding of the limiting plate 44 fixed on the surface of the mounting plate 41 in the middle cavity 43 of the top cover 42. Through the cooperation of the limiting plate 44 and the middle cavity 43, the extraction stroke and range of the sealing extraction rod 112 can be accurately limited, ensuring that the entire pus extraction process is accurately and stably performed according to the set requirements;

[0048] During the extraction of pus, when the pus flows through the position where the dredging blade 21 is located, the blade is in a specific position layout, which can cut and chop the condensate or larger particles in the pus. At the same time, with the extraction and flow of pus in the needle body 122, the flow will generate a force on the dredging blade 21, which promotes the rotation of the dredging blade 21 around the shaft. The rotation of the blade changes the original flow direction and speed distribution of the pus, forming a flow guiding effect, allowing the pus to be more smoothly extracted through the needle body 122, effectively reducing the occurrence of blockage during the entire pus extraction process.

[0049] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
