Abstract

The invention relates to a novel vertebral bone tissue biopsy instrument which comprises an outer tube sampling assembly, an inner tube sampling assembly and a push rod assembly, wherein the outer tube sampling assembly comprises an outer tube sampling handle and a sampling outer tube, the sampling outer tube is fixedly connected with the outer tube sampling handle, an outer tube sampling component is arranged at the far end of the sampling outer tube, and the outer tube sampling component is subjected to reducing treatment; the inner tube sampling assembly comprises an inner tube sampling handle, an inner tube connecting piece, a rotating piece and a sampling inner tube, the outer tube sampling handle is fixedly connected with the inner tube sampling handle, the inner tube connecting piece is fixedly connected with the sampling inner tube, an inner tube sampling component is arranged at the far end of the sampling inner tube, the inner tube sampling component can be composed of one or more sheet structures, by rotating the rotating piece, the sampling inner tube connecting piece and the inner tube advance in the axial direction, the inner tube sampling component advances for closing along the variable-diameter outer tube sampling component, and the bone tissue cutting function is achieved; and the push rod assembly comprises a push rod handle and a push rod, the push rod is fixedly connected with the push rod handle, and the push rod can be inserted into the sampling inner tube in a sliding manner.

Description

Technical field[0001]The present invention belongs to the field of medical devices, and involves a vertebral bone tissue gasking inspection instrument.Background technique[0002]The main indication of transdermal vertebral shaped surgery is an osteoporosis compression fracture and vertebral tumor, wherein the vertebral tumor is the earliest use of transcataria, in order to determine the pathology of tumors, it is necessary to carry out Puncture biopsy. Currently, the most commonly used inventory equipment in the market consists of a knitting portion and the needle tube part, mainly by inserting the vertebral body inside the vertebral body, turning or causes the vertebral bone tissue into the needle tube, and realizes the extraction of the lesion. . However, in clinical feedback, existing instruments are difficult to retain bone tissue in needle tubes during the operation, and there is a large probability that the sufficient bone tissue is not available for pathological testing.[0003]...
