Introducer for fiber bronchoscope

Abstract

The invention provides an introducer for a fiber bronchoscope, which comprises a fixator, a guide tube, a telescopic tube and a telescopic guide sleeve, and is characterized in that one end part of the fixator is connected with one port of the guide tube; a light guide rod of a light supply rod of the guide tube and an insertion optical cable of the fiber bronchoscope can extend into the guide tube and penetrate through the fixator from the groove length direction of the guide tube; the top end of the telescopic tube is connected with the other end of the fixator, the tail end of the telescopic tube penetrates into an inner cavity of the telescopic guide sleeve, the tail end of the telescopic guide sleeve is connected with the fiber bronchoscope body end, and a light guide rod of the lightrod and an insertion optical cable of the fiber bronchoscope sequentially penetrate through the telescopic guide sleeve, the telescopic tube and the guide tube and then are exposed out of the guide tube. The introducer is simple in structure, an inserted optical cable of the fiber bronchoscope can be rapidly guided to reach the glottis, intubation time is shortened, success rate is increased, andsafety of a patient is guaranteed.

Description

technical field [0001] The invention belongs to the field of respiratory medical instruments, in particular to a guide for fiberoptic bronchoscope. Background technique [0002] A bronchoscope is inserted through the mouth or nose into the patient's lower respiratory tract for observation of lung lobes, segmental and subsegmental bronchial lesions, biopsy sampling, bacteriological and cytological examinations, and can be used for photography, teaching and dynamic viewing with the TV system. Recorded medical devices. Through the attached biopsy sampling accessory, it can assist in the detection of early lesions, and can perform internal surgical procedures such as polyp removal. It is suitable for operations such as bronchial and pulmonary disease research and postoperative examination. [0003] German laryngologist Gustav Killian performed the first bronchoscopy in 1897. Killian used a rigid bronchoscope to remove the porcine bone. The procedure is performed while the pa...

AI Technical Summary

Problems solved by technology

[0005] When fiberoptic bronchoscope is used for endotracheal intubation through oral fiberoptic bronchoscope, because the insertion cable is soft and difficult to control, especially when the patient is under general anesthesia, the muscles are relaxed, the base of the tongue falls backward, and the oral passage is narrow, making the operation more difficult. The tube time is significantly prolonged, and the patient's hypoxia time is correspondingly prolonged. If the patient's hypoxia time exceeds 5 minutes, brain cell edema may occur, postoperative cognitive dysfunction, and severe cases may even cause brain death.
