Navigation positioning guide wire for lung biopsy

Abstract

The invention discloses a navigational positioning guide wire for lung biopsy. The navigational positioning guide wire comprises a bronchoscope main body; the channel port is obliquely arranged on the outer side of the circumference of the bronchoscope; the positioning guide wire assembly is detachably arranged in the channel port in a relative sliding manner; the insertion part is connected to one end of the bronchoscope body and used for stretching into the lung of the human body to conduct corresponding lung biopsy, and a corresponding conveying channel is arranged in the insertion part; the wireless positioning sensor is arranged at the end of the positioning guide wire assembly in a sleeving mode, and the wireless positioning sensor stretches into the lung of the human body along with the insertion part and works in cooperation with external image navigation imaging medical equipment; the inner steering guide assembly is coaxially arranged at the end part of the positioning guide wire assembly, and the inner steering guide assembly is used for directionally adjusting a transmission guide track of the wireless positioning sensor; and the end point positioning assembly is fixed at one end of the positioning guide wire assembly.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a navigation and positioning guide wire for lung biopsy. Background technique [0002] Currently, lung cancer is the cancer with the highest morbidity and mortality in the world. Early biopsy diagnosis of lung cancer can greatly improve the survival rate of lung cancer patients. Bronchoscopy is one of the important methods for the early diagnosis and treatment of lung cancer. It can directly observe the lumen of the trachea and bronchi with the naked eye, and at the same time perform biopsy to correctly diagnose the disease. In the prior art, when doing a biopsy under the guidance of bronchoscope navigation, it is necessary to use the positioning guide wire for accurate positioning first, and then carry out the in-depth action of the bronchoscope. However, since the positioning guide wire is inserted, it is difficult to turn at a fixed point, and the expected position ...

AI Technical Summary

Problems solved by technology

In the prior art, when doing a biopsy under the guidance of bronchoscope navigation, it is necessary to use the positioning guide wire for accurate positioning first, and then carry out the in-depth action of the bronchoscope. However, since the positioning guide wire is inserted, it is difficult to turn at a fixed point, and the expected position cannot be reached. Repeated calibration many times, the operation is difficult, and the positioning accuracy is low; at the same time, during the in-depth process of the bronchoscope, the position track of the bronchoscope may deviate, and the position needs to be adjusted again; therefore, those skilled in the art provide a lung biopsy. Navigation and positioning guide wire to solve the problems raised in the above-mentioned background technology
