Four-limb soft tissue tumor puncture sampling device

Abstract

The invention discloses a four-limb soft tissue tumor puncture sampling device which comprises a puncture tube, one end of the puncture tube is detachably connected with a needle drawing cylinder, the needle drawing cylinder is internally communicated with the puncture tube, the puncture tube is connected with a plurality of push rods in an inserted mode, the push rods are distributed around the axis of the puncture tube at intervals, and the ends, away from the needle drawing cylinder, of the push rods are hinged to cutting pieces. A turnover driving part is arranged on the peripheral surface, far away from the tail end of the needle drawing cylinder, of the puncture tube, and the driving end of the turnover driving part directly faces the cutting part; when the hinge points between the cutting pieces and the push rod are pushed by the push rod to directly face the driving end of the turnover driving piece, the cutting pieces are all turned over in the axis direction of the puncture tube relative to the hinge points of the cutting pieces. The device has the function of taking out tumor block samples and liquid samples in a puncture mode. Compared with the prior art, the function of taking out the blocky tumor is added, the taken-out tumor blocky sample can be directly researched conveniently, and the effects of improving the research judgment accuracy and increasing the research speed are achieved.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a puncture sampling device for soft tissue tumors in extremities. Background technique [0002] Soft tissue refers to the skin, subcutaneous tissue, muscles, tendons, ligaments, joint capsules, nerves, blood vessels, etc. of the human body. Soft tissue is a relatively important human tissue. Tumor refers to the new organisms formed by the proliferation of local tissue cells under the action of various carcinogenic factors, because these new organisms are mostly in the form of space-occupying block-like protrusions, also known as neoplasms. [0003] For soft tissue tumors in the body, doctors usually make a comprehensive judgment based on the location, source, size, and time of the tumor, and then perform surgery after finding out the type of tumor. The common treatment method is to remove the tumor and then perform chemotherapy and other physical therapy . Existing tu...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that when sampling tumors, a puncture needle is usually used for extraction. In the process of extraction, only tumor secretions or tumor cavity fluids are usually obtained, and it is difficult to obtain tumors in the form of lumps.

Therefore, when conducting sampling research and judgment, it is impossible to directly study massive tumors, which often increases the difficulty of sampling research and increases the probability of misjudgment in research judgment.

In addition to the function of extracting liquid, the existing puncture needles do not yet have the function of taking out tumor block samples.
