A compound flexible bronchoscope

Abstract

A composite flexible bronchoscope, including an operating part, an insertion part, a bending part, a front end, an eyepiece arranged on the operating part, and a light guide connection part connected with the operating part, and its special feature is that it also includes a metal material The catheter sleeve made, the catheter sleeve includes a straight tube and an oxygen delivery interface arranged at the operation part of the straight tube; when in use, the insertion part is located in the straight tube, and the bending part and the front end are connected from the end of the insertion end of the straight tube The part protrudes; there is a gap between the insertion part, the bending part and the front end part and the inner wall of the straight pipe. Due to the adoption of such a structure, when the insertion part, the bending part and the front end rotate or move forward, there will be no damage to the inner wall of the bronchus; because the bending part and the front end can rotate or move freely, the inspection effect is improved; once the inner wall of the bronchus or In the event of complications during the operation, if a large one occurs, it will be completely drained; foreign bodies in the airway can be successfully completed with this method; it can ensure the safe operation of patients with complicated conditions for a long time.

Description

technical field [0001] The invention relates to a bronchoscope, in particular to a soft bronchoscope. Background technique [0002] In the current prior art, a flexible bronchoscope includes an operating part, an insertion part, a bending part, a front end, an eyepiece arranged on the operating part, and a light guide connecting part connected with the operating part. The problem is: when in use, the insertion part, the bending part and the front end are located in the bronchus, and the insertion part and the bending part move or rotate in the bronchus, which is easy to cause trauma to the inner wall of the bronchus; in order to ensure the effect of the inspection, the insertion part and the Insertion after disinfection of the curved part increases the chance of trauma many times; once complications occur on the inner wall of the bronchus or during the operation, if a large one occurs, there will be serious consequences; foreign bodies in the airway cannot be completed by tr...
