Embodiment Construction

[0028] In the embodiment of the present invention, an automatic pop-up component is added to the outer needle seat. After the toggle button is triggered, the inner needle seat can be automatically ejected under the action of the elastic member, and the doctor can complete the operation alone without the cooperation of others, thereby reducing the number of operations. The staffing in the hospital can improve the work efficiency of doctors, which will be explained in detail below.

Abstract

The invention relates to the technical field of medical supplies, and specially relates to a disposable cytological biopsy needle. The biopsy needle includes an inner needle assembly and an outer needle assembly; the outer needle assembly includes an outer needle base; the inner needle assembly includes an inner needle base; the middle of the outer wall of the outer needle base is provided with aprotruding hand position; a puncture needle includes an automatic pop-up assembly; the automatic pop-up assembly includes an elastic member and a poking button for triggering the elastic member to popup; one end of the elastic member is in contact with the hand position, and the other end of the elastic member is in contact with the inner needle base; the poking button is connected to the outer needle base; and the inner needle base is pushed to move away from the hand position when the elastic member pops up so as to make an inner needle core move in an outer needle tube, so that the outer needle tube located between the end part of the outer needle tube and the end part of the inner needle core can form a sampling space. As the provided biopsy needle is provided with the automatic pop-up assembly, a doctor can accomplish the adjusting and triggering operation of the biopsy needle by using one hand during operations, so that personnel allocation during the operations can be reduced,and the working efficiency of the doctors can be enhanced.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a disposable cytology biopsy needle used for biopsy operations such as thyroid, liver, and pancreatic lymph. Background technique [0002] Thyroid nodules are a common thyroid disease. During detection, a biopsy of the thyroid nodules is required, and the corresponding thyroid cells are taken out for testing to further determine whether the nodules are benign or malignant. Thyroid needle aspiration biopsy is a highly accurate diagnostic method and has been widely used in the diagnosis of nodular thyroid disease. [0003] The thyroid puncture needle includes an inner needle core and an outer needle tube. During biopsy, with the assistance of ultrasound equipment, the needle tip of the puncture needle is inserted into the nodule. At this time, the doctor holds the outer needle seat with one hand to keep the position unchanged, and operates with the other hand. Ultrasonic ...
