[0048] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale.

[0049] Example 1

[0050] Please see the appendix Figures 1-13 As shown, this is the first embodiment of the present invention. This embodiment provides a biopsy sampling device, including a main body component 10. The main body component 10 includes a needle tube 11. A cooling component 12 is provided in the inner cavity of the needle tube 11. A miniature camera 13 is fixedly connected to the left end of the needle tube 11. A display 14 is rotatably connected to the top right side of the needle tube 11. A handle 15 is fixedly connected to the bottom right side of the needle tube 11.

[0051] The sampling component 20 includes a tube assembly 21 disposed in the inner cavity of the main body assembly 10, a control component 22 disposed on the right side of the tube assembly 21, a drive component 23 disposed on the right side of the control component 22, and a lane-changing component 24 disposed on the right side of the control component 22.

[0052] After the needle tube 11 and the tube assembly 21 are punctured and inserted into the patient's body, the control component 22 rotates along the inner lumen of the needle tube 11 and contacts different components inside the tube assembly 21. The drive component 23 is used to drive the tube assembly 21 to contact the pathogen and collect samples. After sampling, the transfer component 24 is used to transfer the subsequent sampling work to other components inside the tube assembly 21.

[0053] Cooling component 12 is used to quickly reduce the temperature of the outer surface of syringe 11;

[0054] A data cable is electrically connected between the miniature camera 13 and the display 14, and the data cable is located in the inner ring area of ​​the cooling component 12.

[0055] It should be noted that the data cable between the miniature camera 13 and the display 14 is made of copper core material, which is intended to avoid affecting the normal operation of the magnetic part inside the control component 22.

[0056] In this embodiment, before biopsy sampling, cold material is first fed into the cooling component 12 to rapidly reduce the surface temperature of the needle tube 11. Then, the control component 22 is rotated so that its pushing part contacts the puncture part of the tube body component 21. At this time, the drive rod 231 of the drive component 23 is pushed forward, pushing the puncture needle 213 of the tube body component 21 out of the needle tube 11 for puncture. During puncture, the miniature camera 13 can capture the image of the front end of the needle tube 11 and display it on the display 14 to assist the doctor in accurately locating the lesion. After puncture, the drive component 23 is first controlled to reset, so that the tube body component 21 is reset. Then, the control component 22 is rotated so that its pushing part contacts the sampling part of the tube body component 21. Then, the drive component 23 is operated again to extend the sampling part and aspirate the lesion sample. After sampling, the external air pump can be quickly switched to other sampling parts of the tube body component 21 by the operation of the switching component 24 to achieve the purpose of multiple sampling.

[0057] Secondly, please refer to it again. Figures 2-4 The cooling component 12 includes a feed tube 121 fixedly connected to the top of the needle tube 11. The bottom of the feed tube 121 is connected to a heat conduction tube 122, which is fixedly connected to the inner wall of the needle tube 11. The top outlet of the heat conduction tube 122 is connected to a discharge tube 123, and the top of the discharge tube 123 extends out of the needle tube 11.

[0058] It should be noted that the heat conduction tubes 122 are arranged in an S-shape in the inner cavity of the needle tube 11 to improve the cooling effect on the outer surface of the needle tube 11, thereby protecting the muscle tissue of the puncture site by using low temperature and reducing the patient's pain. At this time, the temperature of the cooling material should be below 0 degrees Celsius.

[0059] In this embodiment, before puncture, cold material is fed into heat-conducting pipe 122 through feed pipe 121. The refrigerant circulates in heat-conducting pipe 122, thereby rapidly reducing the temperature of the outer surface of needle tube 11. After the refrigerant has cooled down, it is discharged through discharge pipe 123 to achieve the purpose of rapid cooling and recycling.

[0060] Secondly, please refer to it again. Figures 5-13 The tube assembly 21 includes a first frame 211 fixedly connected to the middle of the inner cavity of the needle tube 11, a second frame 212 fixedly connected to the left side of the inner cavity of the needle tube 11, four sets of through grooves are opened in the inner ring of the first frame 211 and the second frame 212, and a set of puncture needles 213 and three sets of sampling tubes 214 are slidably connected in the through grooves. The right end of each sampling tube 214 is connected to a trachea 215. The outer ring of the right end of the puncture needle 213 and the sampling tube 214 is fixedly connected to a first spring 216, and the left end of the first spring 216 is fixedly connected to the right side of the first frame 211.

[0061] The trachea 215 is divided into two sections. The part that extends into the inner ring of the swivel 221 is a rigid tube, while the remaining right side part is a flexible and foldable plastic tube.

[0062] The control assembly 22 includes a rotating ring 221 rotatably connected to the right side of the inner cavity of the needle tube 11. A push rod 222 is slidably connected to the inner ring of the rotating ring 221. A second spring 223 is fixedly connected to the right end of the push rod 222. The left end of the second spring 223 is fixedly connected to the right side of the rotating ring 221. A control knob 224 is rotatably connected to the outer ring of the needle tube 11 outside the position of the rotating ring 221. Four sets of indicator plates 225 are fixedly connected to the outer ring of the control knob 224. Positioning grooves 226 are opened on both the left and right sides of the control knob 224. A groove is opened on the outer ring of the needle tube 11 on the left and right sides of the control knob 224. A third spring 227 is fixedly connected in the groove. A sliding ball 228 is fixedly connected to the other end of the third spring 227. The sliding ball 228 is movably inserted into the positioning groove 226. Strong magnetic blocks 229 are fixedly connected to the outer ring of the rotating ring 221 and the inner ring of the control knob 224, and the positions of the two sets of strong magnetic blocks 229 are corresponding.

[0063] The drive assembly 23 includes a drive rod 231 slidably connected to the right side of the needle tube 11. A fixed plate 232 is fixedly connected to the right end of the drive rod 231. A fourth spring 233 is fixedly connected to the left side of the fixed plate 232. The left end of the fourth spring 233 is fixedly connected to the right side of the needle tube 11. A handle 234 is fixedly connected to the bottom of the fixed plate 232.

[0064] The lane-changing assembly 24 includes a sleeve 241 fixedly connected to the right side of the fixed plate 232. A slide rod 242 is slidably connected to the inner cavity of the sleeve 241. An air suction pipe 243 is fixedly connected to the outer ring of the slide rod 242 extending out of the sleeve 241. The inlet of the air suction pipe 243 is movably inserted into the outlet of the air pipe 215. A fifth spring 244 is fixedly connected to the left end of the slide rod 242. The right end of the fifth spring 244 is fixedly connected to the right side of the inner cavity of the sleeve 241.

[0065] It should be noted that the right end of the puncture needle 213 and the sampling tube 214 is provided with a compression plate with a larger diameter, and the left and right ends of the push rod 222 and the left end of the drive rod 231 are also provided with compression plates.

[0066] A through groove is provided in the middle of the rotating ring 221, and all three sets of air pipes 215 pass through the through groove. This is intended to allow the air pipes 215 to fold and retract within the gap between the driving rod 231 and the rotating ring 221 when the driving rod 231 moves, so as to avoid affecting the movement of the driving rod 231.

[0067] In this embodiment, during the puncture operation, rotating the control knob 224 causes the sliding ball 228 to be pushed back into the inner cavity of the needle tube 11 by the positioning groove 226. During the rotation of the control knob 224, it is continuously pushed into the positioning groove 226 by the third spring 227, creating a jerky feel and improving the rotation experience and positioning accuracy. Since the control knob 224 and the rotating ring 221 are attracted to each other by the strong magnetic block 229, the rotation of the control knob 224 will drive the rotating ring 221 to rotate synchronously. The rotating ring 221 will then drive the push rod 222 to rotate within the needle tube 11 until the left end of the push rod 222 contacts the puncture needle 213 on the first frame 211. At this time, pushing the drive rod 231 causes the left end of the drive rod 231 to push the right end of the puncture needle 213 to slide forward within the through groove of the first frame 211, extending out of the needle tube 11 for the puncture operation. After the puncture is completed, release the handle 234. The elastic force of the fourth spring 233 resets the drive rod 231, and the puncture needle 213 and the push rod 222 are also reset via the first spring 216 and the second spring 223. Next, turn the control knob 224 again until the left end of the push rod 222 contacts a set of sampling tubes 214 on the first frame 211. Since the right end of the sampling tube 214 is connected to the air tube 215, it can be easily connected to an external air pump or other sampling equipment. After the push rod 222 contacts the sampling tube 214, push the drive rod 231 again. The left end of the drive rod 231 will push the right end of the sampling tube 214, causing the sampling tube 214 to extend out of the needle tube 11 for sampling. After sampling is completed, when the next sampling is needed, simply pull the slide bar 242. The fifth spring 244 is compressed, and at the same time, the slide bar 242 pulls the suction pipe 243 out of the current air pipe 215. Then, rotate the slide bar 242 to the outlet of the next set of air pipes 215, release the slide bar 242, and the elastic force of the fifth spring 244 will reset the slide bar 242. At the same time, the inlet of the suction pipe 243 is inserted into the new air pipe 215, realizing the switching operation of the air pump and improving sampling efficiency.

[0068] Example 2

[0069] This embodiment is the second embodiment of the present invention, which provides a method for using a biopsy sampling device, applicable to the above-described method for using a biopsy sampling device, including:

[0070] S1, an external air pump is connected, and the air inlet of the air pump is connected to the suction pipe 243. At this time, the suction pipe 243 is connected to a set of air pipes 215 and sampling pipes 214 to facilitate subsequent sampling operations.

[0071] S2, by rotating the control knob 224, the push rod 222 is moved to the right side of the puncture needle 213, and the handle 234 and the push rod 222 are pushed to make the puncture needle 213 extend out of the needle tube 11;

[0072] S3, through external cold material, is introduced into the cooling component 12 to quickly reduce the surface temperature of the needle tube 11, and after cooling, the needle tube 11 and puncture needle 213 are pushed into the patient's body, and the source of the disease is reached through the miniature camera 13 and the display 14.

[0073] S4. After the puncture is completed, reset the handle 234, then adjust the top rod 222 to the right side of the sampling tube 214, push the handle 234 again to make the sampling tube 214 extend out of the needle tube 11, and through the external air pump, create negative pressure inside the suction tube 243 and the air tube 215 to suck the sample into the sampling tube 214.

[0074] S5. After sampling is completed, repeat step S4 again, move the top rod 222 to the right side of the remaining sampling tubes 214, and perform multiple samplings.

[0075] In this embodiment, it is necessary to ensure that all components of the biopsy sampling device are correctly installed and that the tightness of all connecting parts is checked. By connecting an external air pump to the suction pipe 243, a negative pressure environment is ensured during the sampling process, guaranteeing the smooth aspiration of the sample.

[0076] In step S3, external cooling material is rapidly introduced into the cooling assembly 12, causing the surface temperature of the needle 11 to drop quickly. This step is crucial because it not only ensures a low-temperature environment during the puncture process, reducing patient discomfort, but also provides ideal temperature conditions for subsequent sampling. Next, the needle 11 and puncture needle 213 are advanced, and real-time feedback from the miniature camera 13 and display 14 ensures they accurately reach the lesion location.

[0077] Once the puncture is complete, quickly reset the handle 234, and then carefully adjust the push rod 222 to the right side of the sampling tube 214. Push the handle 234 again, and the sampling tube 214 will extend under the guidance of the needle tube 11, ready for sampling. At this time, we start the external air pump to create negative pressure inside the suction tube 243 and the air tube 215, and the sample is smoothly drawn into the sampling tube 214 under the action of negative pressure.

[0078] In step S5, although step S4 is repeated, the push rod 222 is moved to the right side of a different sampling tube 214 each time to ensure that enough samples are obtained from the source of the disease to provide sufficient material for subsequent pathological analysis.

[0079] Throughout the entire process, we maintained meticulous operation and real-time monitoring of the biopsy sampling device to ensure the accuracy and safety of each step. At the same time, we also considered patient comfort and pain levels, always prioritizing the patient's interests. Through this biopsy sampling device and its detailed operating instructions, we provide healthcare professionals with an efficient, safe, and accurate biopsy sampling solution.

[0080] The working principle of this invention is as follows: Before puncture, cold material is fed into the heat-conducting pipe 122 through the feed pipe 121. The refrigerant circulates within the heat-conducting pipe 122, thereby rapidly reducing the temperature of the outer surface of the needle tube 11. During the puncture operation, the control knob 224 is rotated, causing the sliding ball 228 to be pushed back into the inner cavity of the needle tube 11 by the positioning groove 226. During the rotation of the control knob 224, it is continuously pushed into the positioning groove 226 by the third spring 227, creating a jerky sensation and improving the rotation experience and positioning accuracy. Since the control knob 224 and the rotating ring 221 are attracted to each other through the strong magnetic block 229, the rotation of the control knob 224 will drive the rotating ring 221 to rotate synchronously. The rotating ring 221 will then drive the push rod 222 to rotate within the needle tube 11 until the left end of the push rod 222 contacts the puncture needle 213 on the first frame 211. At this point, pushing the drive rod 231 causes the left end of the drive rod 231 to push the right end of the puncture needle 213 to slide forward within the slot of the first frame 211, extending the needle tube 11 for puncture. During the procedure, a miniature camera 13 captures an image of the tip of the needle tube 11, which is then displayed on the monitor 14 to assist the doctor in accurately locating the lesion. After the puncture is completed, releasing the handle 234 causes the drive rod 231 to reset, and the puncture needle 213 and the push rod 222 also reset via the first spring 216 and the second spring 223. Next, the control knob 224 is rotated again until the left end of the push rod 222 contacts a set of sampling tubes 214 on the first frame 211. Since the right end of the sampling tube 214 is connected to an air tube 215, it can be easily connected to an external air pump or other sampling equipment. After the push rod 222 contacts the sampling tube 214, the drive rod 231 is pushed again. The left end of the drive rod 231 pushes the right end of the sampling tube 214, causing the sampling tube 214 to extend out of the needle tube 11 for sampling. After sampling, when the next sampling is needed, simply pull the slide rod 242. The fifth spring 244 is compressed, and the slide rod 242 pulls the suction tube 243 out of the current air tube 215. Then, rotate the slide rod 242 to the outlet of the next set of air tubes 215, release the slide rod 242, and the elastic force of the fifth spring 244 resets the slide rod 242. At the same time, the inlet of the suction tube 243 is inserted into the new air tube 215, realizing the switching operation of the air pump and improving the sampling efficiency.
