Pet tumor inspection sampling device

Abstract

The invention discloses a pet tumor inspection sampling device. The device comprises a puncture needle tube (1) of a hollow tubular structure, one side of the end of the puncture needle tube (1) axially extends out of a guiding plate (2) concentric with the puncture needle tube (1), and an inclined panel (3) as a puncture needle end is arranged at the end of the guiding plate (2); a first piston (4) and a second piston (5) which are in compact sliding fit with the puncture needle tube (1) are arranged inside the puncture needle tube (1), and the first piston (4) and the second piston (5) are fixed into a whole through a connecting rod (6). The device is simple in structure, can puncture tumor tissue of various textures, can successfully extract tissue samples inside tumors, and provides guarantees for later quality schemes and treatment courses.

Description

technical field [0001] The invention relates to the technical field related to pet medical equipment, in particular to a pet tumor inspection and sampling device. Background technique [0002] Tumor puncture biopsy is one of the important means to determine the nature of the tumor. Through cytological examination after puncture, it can be determined whether the tumor is benign or malignant. At present, the common sampling methods of puncture needles are mainly divided into: 1. The needle tip that directly extracts the tissue fluid inside the tumor 2. The needle tip is equipped with a biopsy needle with a needle point to hook the internal tissue of the tumor; 3. The hollow three-pointed Biopince biopsy gun can directly dig out the surface tissue of the tumor; [0003] The above puncture structures are first of all, although the biopsy needle can puncture into the inside of the tumor for sampling, but its disadvantages are also obvious. If the tumor tissue is hard, there will ...

AI Technical Summary

Problems solved by technology

[0003] The above puncture structures are first of all, although the biopsy needle can puncture into the inside of the tumor for sampling, but its disadvantages are also obvious. If the tumor tissue is hard, there will be tissues or interstitial fluids that are not easy to grasp or extract into the interior, and Biopince The representative biopsy gun needle has a thicker body, which is good for grabbing hard tumor tissue, but due to its structural limitation, it can only grab the surface tissue of the tumor, and the sampled surface tissue often has larger defects compared with the whole body. difference
