The invention relates to a tumor three-layer biopsy device. The problems that tumor cells are inconvenient to sample, and infection is easily caused are effectively solved. According to the technicalscheme, the tumor three-layer biopsy device comprises a box body. An upper end cover is arranged on the box body, a guide rod is fixed into the box body, a sleeve sleeves the guide rod, and a right movable plate and a left movable plate are fixed to the left end of the sleeve. A first compression spring and multiple telescopic rods are connected between the left movable plate and the right movableplate. Vertical connecting rods are connected to the left movable plate and the right movable plate. Connectors matched with a pintle are mounted at the upper ends of the left connecting rod and theright connecting rod and the left side of the box body, levers are symmetrically arranged in the box body front and back, a wedge block for limiting the left movable plate from moving leftwards are arranged at the left ends of the levers, the sleeve is pressed inwards, the right movable plate can move leftwards, after the right movable plate moves rightwards by a certain distance, the left ends ofthe levers move outwards, and the left movable plate is released and moves leftwards. The sleeve is loosened, and the left movable plate and the right movable plate are reset rightwards simultaneously. By means of the device, the portability and the safety of tumor cell puncture sampling are improved.
Description
technical field [0001] The invention relates to the field of biopsy puncture, in particular to a three-layer tumor biopsy device. Background technique [0002] A biopsy needle is a medical device used for biopsy sampling and cell absorption. The biopsy needle is often used together with a biopsy gun; a biopsy gun is a device that is often used. After the tissue is detected, the biopsy gun is pulled out. At present, the biopsy needles for semi-automatic or fully automatic biopsy guns on the market are generally composed of an inner solid needle and an outer hollow needle; that is, it is composed of two layers; it is widely applicable, safe and effective. [0003] However, for tumor cells, especially malignant tumor cells, the above-mentioned double-layer needle is not suitable, because the needle is placed inside the tumor cells during sampling, and when the sampling needle is pulled out, it is easy to cause tumor cells to spread along the needle path Case. Therefore, the ...
