Abstract

The invention relates to the technical field of clinical medical treatment, and discloses a tissue biopsy needle. The tissue biopsy needle comprises a power mechanism, an outer sleeve needle and an inner core needle, wherein the inner core needle is embedded in the outer sleeve needle, a groove is formed in the side wall of the tail end of the outer sleeve needle, a semi-ring cutter correspondingto the groove is arranged on the inner core needle, and the power mechanism drives the semi-ring cutter to transversely rotate in the outer sleeve needle through a needle rod. The tissue biopsy needlehas the beneficial effects that in the process that a cutter opening of the inner core needle and a side cutter act together to cut tissue, the power mechanism drives the semi-ring cutter to rotate rapidly through the needle rod, rapid rotary cutting of the tissue to be detected is achieved to form a complete cylindrical sample, and the tissue is convenient to detect. In the cutting process, dueto the fact that rotary cutting is adopted, the outer sleeve needle and a needle tip are static, shaking cannot occur, damage to surrounding important organs is avoided, safety is greatly improved, and biopsy can be conveniently carried out on tissue such as large vascular gaps, dangerous organ sides, small nodules and lymph nodes.

Description

technical field [0001] The invention relates to the technical field of clinical medicine, in particular to a tissue biopsy needle. Background technique [0002] Puncture sampling refers to the use of a puncture needle to conduct biopsy needles for deep tissue targets under the guidance of CT images, ultrasound images or MRI images in the modern medical process, and to cut a small amount of pathological tissue for sampling and testing. Therefore, biopsy puncture is an indispensable medical behavior in the process of disease diagnosis and treatment. [0003] There are many kinds of existing biopsy needles, and most of them are biopsied along the axis of the needle. pose great risks. In particular, biopsies near large vessels or major tissues pose great dangers. Biopsies in these risky areas are often abandoned by clinicians and are referred to as no-puncture no-go areas. Contents of the invention [0004] The object of the present invention is to provide a tissue biopsy ...
