Abstract

A liver biopsy puncture needle includes a needle cannula, wherein a cutting window is arranged at a position close to the needle head of the puncture needle cannula; the needle tail position of the puncture needle cannula is provided with a handgrip; a cut needle core is pierced in the cannula of the puncture needle; a cut needle core includes a positioning block; the cutting section is a fixing piece adapted to the inner wall of the puncture needle cannula; the fixing piece is provided with a cutting blade; the outer structure of the cutting blade is adapted to the outer structure of the cutting window; the side of the cutting blade is provided with a tissue fixing piece; and the needle body of the cutting needle core is provided with a positioning block. The invention discloses a liveerbiopsy puncture needle and a use method thereof. The puncture needle has simple structure, and only needs the cooperation of a puncture needle cannula and a cutting needle core to complete the puncture operation. One or more tissues can be punctured at the pathological part at one time, and one or more tissue can be punctured at different positions at the pathological part at one time.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a liver biopsy puncture needle and a method for using the same. Background technique [0002] Biopsy is a primary method for obtaining histopathological diagnosis of bone and soft tissue tumors. Bone and soft tissue tumors are diseases that seriously endanger human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of examination methods and methods, the correct rate of diagnosis has gradually increased, but there are still a large part of tumors that do not have typical imaging features, making diagnosis difficult. Correct diagnosis requires a combination of clinical, imaging and pathological diagnosis. Among them, pathological diagnosis plays a key role in th...
