Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide an endoscopic puncture sampling needle for bronchoscopy, which has a simple structure, provides protection for the sampling needle when it is withdrawn, is easy to operate and can effectively solve the problem that traditional sampling needles rely entirely on hand feeling when in use. Controlling the depth of the sampling needle will lead to problems such as inaccurate control and too little tissue in the grasped lesion for pathological examination

Embodiment Construction

[0029] The present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 As shown, a kind of endoscopic puncture sampling needle used for bronchoscope of the present invention comprises a handle 1, a needle core 12, a syringe 11 and a needle tube 2 fixed on the handle 1 and connected with the syringe 11, and the needle tube 2 is covered with an inner diameter Slightly larger than the needle sheath 3 of the needle tube 2, the end of the needle tube 2 near the needle tip 6 is provided with a trapezoidal sampling groove 7 with a cross-sectional height of 0.2mm and two base angles of 30 degrees. The connection end between the needle sheath 3 and the handle 1 is a sleeve tube 4 which is provided with a groove and connected with the connector 8, and the sleeve tube is made of hard plastic. One end of the handle 1 is a concave structure into which the cannula 4 can be inserted, and a protrusion 5 ...

Abstract

An endoscopic puncture sampling needle for bronchoscopy, comprising a handle, a needle core, a syringe and a needle tube fixed on the handle and connected to the syringe, the needle tube is covered with a needle sheath with an inner diameter slightly larger than the needle tube, and the needle sheath A sleeve is provided at the connection end with the handle, and the surface of the sleeve is provided with a groove. One end of the handle is a concave structure for insertion of the sleeve, and the inner wall of the concave structure is provided with a groove depth and There are two protrusions with matching width, and there are two grooves, both of which include a placement area. The placement area communicates with the working channel through an "L"-shaped moving channel, and an active area is provided on one side of the moving channel; this The invention is simple in structure, easy to operate, and provides protection for the sampling needle when it is withdrawn. It is suitable for bronchoscopes of different lengths, and effectively solves the problems of inaccurate control and grasping of lesions when the traditional sampling needle is completely controlled by the hand feeling when using the sampling needle. Problems with too little tissue to detect.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an endoscopic puncture sampling needle used for bronchoscopes. Background technique [0002] A bronchoscope is a flexible endoscope with an optical system and a mechanical operating system. It is inserted through the patient's mouth and nose, and can perform various diagnostic and therapeutic operations on respiratory diseases by directly peeking at the lesion of the lungs, or use The sampling needle is inserted into the lesion outside the lumen, and a small amount of tissue is extracted by needle aspiration and sent for pathological examination to confirm the diagnosis. It is playing an increasingly important role in the field of modern respiratory medicine. The simple structure of the sampling needle currently used clinically often causes the following problems. [0003] 1. Without a fixing device, there is a risk of the sampling needle moving during the puncture process, w...
