Abstract

The biopsy sampler comprises an outer sleeve girdling mechanism, a sampling mechanism and an inner insertion puncture mechanism, the outer sleeve girdling mechanism comprises an outer sleeve clamping head and an outer sleeve girdling pipe, the outer sleeve girdling pipe is arranged at the insertion end of the outer sleeve clamping head, and the sampling mechanism comprises a sampling clamping head and a sampling pipe. The sampling pipe is arranged at the inserting end of the sampling clamping connector, the other end of the sampling clamping connector is provided with a negative pressure mechanism connecting block, the sampling pipe is inserted into the outer sleeve girdling pipe, the sampling end of the sampling pipe is of a spiral structure, the inner inserting puncture mechanism comprises a puncture clamping connector and a puncture rod, and the puncture clamping connector is connected with the outer sleeve clamping connector in a clamped mode. The puncture rod is arranged at the insertion end of the puncture clamping head, the puncture rod is inserted into the sampling pipe, and after puncture is completed and the puncture rod is taken down, the sampling clamping head is connected with an air suction pipe of the negative pressure adsorption mechanism through the negative pressure mechanism connecting block. The problems that when an existing biopsy sampler is used for sampling a bone tumor part, sampling is inconvenient, and samples cannot be taken out completely are solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an orthopedic biopsy sampler. Background technique [0002] When biopsying a bone tumor, it is necessary to take a sample. At this time, a device is needed, that is, a biopsy sampler. However, the existing biopsy sampler has two disadvantages. The first is that the sampling end of the sampling tube is a scoop. Therefore, it is not suitable to take out the deboned tissue debris. Second, there is no negative pressure mechanism, so it is inconvenient to take out the tissue fluid or jelly-type diseased tissue in the diseased part. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an orthopedic biopsy sampler, which solves the problems of inconvenient sampling and incomplete samples taken by the existing biopsy sampler when sampling the bone tumor part. [0004] In order to solve the above-mentioned technical problems, the present invention adop...
