Problems solved by technology

[0005] The biopsy needles currently used are usually serrated puncture heads, which can obtain more tissue and guide the tissue into the puncture tube to complete sampling, but this type of puncture head will cause greater damage to the skin and tissues during the puncture process, and it is prone to puncture. Dangerous; while the traditional single-tip puncture head cannot obtain enough biopsy tissue because of smooth puncture

Abstract

The invention discloses a rotary sampling puncture needle. The rotary sampling puncture needle comprises a needle pipe assembly, a limiting assembly, a coating structure and a transmission assembly, the needle pipe assembly comprises an outer sheath pipe and an inner rotating needle; the inner rotating needle is arranged in an outer sheath pipe; the outer sheath pipe and the inner rotating needle are both single-tip needle heads; one end of the limiting assembly is connected with the outer sheath pipe, and the other end of the limiting assembly is connected with the coating structure; the transmission assembly is arranged in the coating structure and is connected with the coating structure; the inner rotating needle is arranged at the top of the transmission assembly and can rotate along with the transmission assembly; the limiting assembly comprises an outer sheath pipe mounting seat; and the outer sheath pipe mounting seat is connected with the outer sheath pipe. The design scheme has the beneficial effects that (1) the outer sheath pipe and the inner rotating needle are combined for sampling, so that the injury to other organs during an operation is reduced; (2) the inner rotating needle can rotate to accurately sample a target area; and (3) the outer sheath pipe and the inner rotating needle are disposable articles, so that cross infection of patients is avoided.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, and is specifically related to a rotary sampling puncture needle. Background technique [0002] The biopsy is the "living tissue examination" referred to as the survey of surgery, which refers to the need for diagnosis and treatment, from the patient's body, clamp or puncture, etc., to take out the lesion tissue, and conduct pathological examination techniques. It is the most important part of diagnosis of patients. It can make a clear histopathological diagnosis of most of the test cases, as a clinical important diagnosis. [0003] The biopsy needle is the main surgical instrument of biopsy, is widely used in the kidney, liver, lung, breast, thyroid, prostate, pancreas, testicles, uterus, ovaries, and sampling surgery. [0004] At present, in clinical operation, it is first to find the location of the sample to be sampled by endoscopy, and then the puncture needle into the predetermin...
