Problems solved by technology

The existing lung cancer sampling device realizes the sampling of lung cancer cells at different depths through the sampling needle in the needle tube, but during the sampling process, the sampling needle needs to enter different depths and levels of the patient's lungs multiple times, which increases the accuracy of the operation of medical staff , Repeatedly entering the patient's lungs is likely to increase the patient's trauma, cause complications, and increase infection

Abstract

The invention discloses a clinical sampling device for lung cancer tumors, which belongs to the technical field of medical apparatus and instruments, and comprises a sampling tube, the outer wall of sampling tube is provided with a fixed tube, the upper end of sampling tube is connected with a storage tube, and the sampling tube is internally and movably provided with a piston; clinical sampling device comprises at least two push rods, the lower ends of the push rods are connected with the upper end of the piston, the upper ends penetrate through the storage tube, and the penetrating parts are connected with push plates; a puncture tube is arranged in the sampling tube and a sealing tube at the same time, and the puncture tube is detachably connected with a connector; a plurality of gradient-shaped fracture openings are formed around the lower end wall of the puncture tube; a plurality of gradient-shaped detachable sampling openings are formed around the lower end wall of a puncture needle, and the position of each sampling opening corresponds to the position of a corresponding fracture opening; and a plurality of sampling devices are uniformly and detachably arranged on the storage tube. According to the invention, one-time multidirectional sampling can be realized, the influence caused by repeated sampling is avoided, the easy blockage in the sampling process is avoided, and the lung cancer sampling convenience is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a clinical sampling device for lung cancer tumors. Background technique [0002] Lung cancer, also known as bronchial lung cancer, is one of the most common malignant tumors in the world today. The incidence rate has a clear upward trend in most countries. The harm of lung cancer is not only reflected in the continuously increasing incidence and mortality. At present, my country The incidence of lung cancer is on the rise, and it has become one of the leading causes of death among urban and rural residents in our country, seriously threatening the health of our people. Therefore, the control of lung cancer has become an issue of widespread concern around the world. Studying the epidemiological characteristics of lung cancer and related general concerns, and studying the epidemiological characteristics of lung cancer and its related risk factors are of great imp...
