A puncture and localization device for pulmonary nodules under CT guidance

Abstract

The invention discloses a lung nodule puncturing and positioning device applied to CT (Computed Tomography) guidance. The device comprises a needle cylinder, a positioning needle arranged in the needle cylinder, a needle end fixed part arranged on the positioning needle and located between the positioning needle and the needle cylinder, a needle head fixed part arranged on the front end of the needle cylinder, and a positioning base arranged under the needle cylinder. The positioning needle comprises a positioning needle head and a hollow needle body arranged on the tail end of the positioning needle head; a plurality of overhead hooks are arranged on the head part of the positioning needle head; a tail line is arranged on the tail part of the positioning needle head, penetrates through the hollow needle body and extends to the outer part of the hollow needle body. The lung nodule puncturing and positioning device applied to CT guidance provided by the invention has the advantages that the positioning needle can be objectively and quickly sent to the accurate position; meanwhile, a hemisphere seat can be rotated to make puncture in various angles more easy, the improved positioning needle with the overhead hooks can effectively prevent the needle head from prolapsing from lung tissues, and the original steel wire is replaced with the tail line, so that the pain caused by the steel wire penetrating through skins after a patient is positioned can be relieved, and the movement of a limb at the side after positioning cannot be limited.

Description

technical field [0001] The invention belongs to the technical field of auxiliary medical devices, and in particular relates to a lung nodule puncture positioning device applied under the guidance of CT. Background technique [0002] Lung cancer is one of the malignant tumors with the fastest increasing morbidity and mortality and the greatest threat to the health and life of the population. The morbidity and mortality of male lung cancer in my country rank first among all malignant tumors. In recent years, due to the popularization of high-resolution CT (HRCT), the detection rate of early lung cancer has been greatly improved. Early lung cancer manifests as small nodules in the lungs. For nodules that are similar in texture to lung tissue or smaller, it is difficult for doctors to determine the location of the lesion during surgery. [0003] The commonly used nodule localization techniques include Hogwire and spring coil localization, etc. During the implementation of thes...

AI Technical Summary

Problems solved by technology

In the current situation, doctors usually insert needles by hand based on their experience. The direction and depth are closely related to the doctor's experience. For novices and less experienced operators, it is difficult to place the positioning needle in the proper position.

At the same time, Hogwire is easy to prolapse when locating superficial nodules, and it is difficult to find during operation when the coil is locating deep nodules. These problems need to be solved urgently
