Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a biopsy sample secondary sampling device. Background Art

[0002] Biopsy sampling plays a pivotal role and significance in tumor diagnosis and other treatment methods. Usually, biopsy samples are divided into dozens of parts for pathological testing of different projects. In the prior art, biopsy sampling is usually performed by puncture sampling with a biopsy needle, and the sample taken out is generally no more than 2 cm. In this case, due to the narrowness of the puncture needle tube, the amount of sample that can be taken out is very limited. It is very important to take out the sample completely for the second time.

[0003] In the prior art, secondary sampling of biopsy needles is usually performed by using a core rod to poke out the sample. In this case, since the tumor sample itself is soft, it is easy to cause the sample to be squeezed, ruptured, and partially retained in the needle tube during the poke-out process. In this case, it is very unfavorable for the segmentation of the sample. There is currently a lack of corresponding solutions for the above situation. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a biopsy sample secondary sampling device which uses an air blowing device to blow out the sample in the needle tube, improves the secondary sampling integrity, and has a simple structure and low cost.

[0005] The device comprises an air bag, and a one-way air inlet valve is arranged at the rear of the air bag;

[0006] An air blowing connector is provided at the front of the air bag, and the air blowing connector is plug-in or threadedly connected to the air bag;

[0007] An air blowing channel is arranged in the air blowing joint, and an airtight ring is arranged in the air blowing channel.

[0008] The effect achieved in this way is that after the sampling needle is pulled out, it is inserted into the air blowing channel. The airtight ring ensures the airtightness of the connection between the needle tube end and the air blowing connector. By squeezing the air bag for one-way air intake, the biopsy sample in the needle tube can be completely blown out.

[0009] The beneficial effects of the utility model are as follows: the utility model solves the problem of difficulty in secondary sampling of biopsy samples in the prior art, realizes complete secondary sampling of biopsy samples, avoids sample rupture and fracture, and is conducive to subsequent segmentation and pathological detection. In particular, the equipment has a simple structure, low cost, can be combined and disassembled for easy cleaning and disinfection, and has the conditions for repeated use, which is of great medical promotion value.
