Please refer to Figures 1 to 3. The utility model provides a technical solution:

A needle-puncture tissue sampling device for medical laboratory includes a puncture component 1; a main body component 2, which is arranged inside the puncture component 1; and a sampling component 3, which is connected to the upper end of the main body component 2; wherein the main body component 2 forms a rotating structure with the puncture component 1 through the sampling component 3. The utility model performs needle-puncture tissue sampling on patients through the arrangement of the puncture component 1, the main body component 2 and the sampling component 3, and the puncture component 1, the main body component 2 and the sampling component 3 are used in coordination. The sampling component 3 can be used to rotate the main body component 2 to scrape the living tissue. Multiple tissue scraping operations can be performed during one puncture process, thereby reducing the number of punctures and increasing the amount of living tissue extracted.

Specifically, the puncture assembly 1 includes a puncture needle tube 101, a needle 102, which is arranged at the bottom of the puncture needle tube 101, and a fixing block 103, which is arranged at the top of the puncture needle tube 101. The utility model uses the fixing block 103 to cooperate with the sampling assembly 3 to achieve the function of limiting, thereby preventing the main assembly 2 from being inserted too deeply and causing damage to the human body.

It is worth noting that the main body component 2 includes a sampling tube 201 inserted into the puncture needle tube 101, a support cover 202 arranged at the bottom of the sampling tube 201, and a scraping groove 203 opened on one side of the sampling tube 201. The utility model uses the support cover 202 to support the scraped living tissue, prevents the sampling tube 201 from leaking downwards during the extraction process, and improves its stability.

In addition, the sampling assembly 3 includes a pull rod 301 connected to the top of the sampling tube 201; a guide block 302, which is provided in two groups, and the two groups of guide blocks 302 are arranged on the pull rod 301; a limit handle 303, which is arranged at the top of the pull rod 301; and a finger groove 304, which is opened on the side of the limit handle 303. The pull rod 301 and the guide block 302 are fixedly connected, and the length between the pull rod 301 and the guide block 302 is consistent with the diameter of the puncture needle tube 101. The utility model arranges the pull rod 301 and the guide block 302, and the guide block 302 is used to make the pull rod 301 and the puncture needle tube 101 close to each other, so as to avoid the pull rod 301 from shaking when the sampling tube 201 is pulled out.

Working principle: When extracting living tissue from a patient's body, first insert the puncture needle tube 101 into the patient's body with the bottom needle 102, then push the limit handle 303, so that the pull rod 301 connected below it pushes the sampling tube 201 deeper into the skin, and then manually rotate the limit handle 303 to rotate the sampling tube 201 to scrape the living tissue from the body. After scraping, rotate the limit handle 303 to pull the sampling tube 201 outward, and the sampling is completed.

The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
