Biopsy device

Abstract

A biopsy device comprises a needle tubing, a needle tubing seat, a handle, a handle cover, a safety device, a needle core and a triggering switch. The handle is provided with a slideway. The slideway is provided with a positioning clamp. The needle tubing seat is slidably limited on the slideway. A spring guide column is fixed at the top of the handle. A spring is mounted between the spring guide column and the needle tubing seat. The needle core penetrates the spring guide column, the spring, the needle tubing seat and the needle tubing. The triggering switch is fixed at the top end of the needle core. A triggering column parallel with the needle core is fixed at the bottom of the triggering switch. A triggering head is disposed corresponding to the positioning clamp at the back of the slideway. The safety device is disposed on the triggering switch which comprises a safety column and a triggering button. The safety column can be abutted against the bottom of the triggering switch and the top of the handle and used for stopping the triggering head from being triggered to release the positioning clamp. The triggering button matched with the safety column is movably fixed at the bottom of the triggering switch and used for controlling the safety column to be abutted against or leave the bottom of the triggering switch and the top of the handle. By the biopsy device, accidental triggering during sampling can be avoided.

Description

technical field [0001] The invention relates to a biopsy device, in particular to a biopsy device with a flexible and convenient firing safety switch during use. Background technique [0002] The biopsy device is a medical device, suitable for various organs such as kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, body surface, etc. It can be used for living tissues of pyramidal tumors and unknown tumors, etc. Sampling and aspiration of cells. The outer needle is detachable, and hemostatic agent and treatment can be injected. It is light, compact and easy to use. [0003] However, the existing biopsy devices are often prone to accidental triggering because there is no effective safety device to fix the biopsy device after the biopsy device is wound; operation, it is necessary to carry out the puncture operation of the biopsy device again; the existing biopsy device, due to its imperfect structure and function, is easy to cause operator erro...

Problems solved by technology

[0003] However, the existing biopsy devices are often prone to accidental triggering because there is no effective safety device to fix the biopsy device after the biopsy device is wound; operation, it is necessary to carry out the puncture operation of the biopsy device again; the existing biopsy device, due to its imperfect structure and function, is easy to cause operator errors in operation, and cannot reduce the number of biopsy punctures of the patient, which not only greatly It reduces the efficiency of the biopsy operation, and at the same time it is a kind of harm to the patient
