Abstract

A breast biopsy sampling probe is provided. An outer cannula is fixed at one end of a casing, and the other end of the casing is connected to a collecting box via a joint. The outer cannula with an inner cannula inserted and a transmission mechanism are installed in the casing, and the transmission mechanism is formed by an inner cannula gear fixed on a gear shaft, an outer cannula gear at one endof the casing and a moving gear fixed on an outer screw sleeve. The outer screw sleeve and an inner screw sleeve are meshed and connected on the gear shaft, and the inner screw sleeve is fixed on theinner cannula via a connecting sleeve. The transmission mechanism is connected to an external driver of the casing for work, and two ends of the casing are in respective fastening fit with a gear sleeve and a marking seat connected with a fixed seat to form the whole. One end of the gear sleeve is directly manufactured into the outer cannula gear to be coaxial with the inner cannula and the moving gear. The probe is compact in structure, small in volume, good in sealing performance and low in manufacturing cost. The parts are assembled and fixed through fasteners, hooks, claws, studs and keyson the parts completely without any tool. The driver is installed outside the casing for easy operation and adjustment. The probe is wide in use range, fast and convenient to operate and high in practicability.

Description

technical field [0001] The present invention relates to a medical device, in particular a breast biopsy sampling probe for obtaining and delivering living tissue samples. Background technique [0002] Sampling of lesion tissue in the breast, providing diagnosis for doctors or providing histological examination for partial and complete resection of abnormal tissue under imaging. [0003] Because percutaneous biopsy is much less invasive than open biopsy, and the patient's pain is less, so that local anesthesia can be used without local anesthesia, while maintaining the beauty of women, so a thin probe is used to dissect suspicious tissue masses. The sampling method for removing fluid and cells in the medium is widely used in clinical practice. [0004] Patent No. 200710141906.5 "Vacuum injector-assisted biopsy device" also provides a device for examining abnormal tissue samples in the breast for the purpose of diagnosis or treatment, but its structure is complicated, and the...
