Novel plugging device capable of realizing visual bronchus plugging and positioning and visual observation at any time during operation

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a novel plugging device capable of realizing visual bronchus plugging and positioning and visual observation at any time during operation, which comprises a bronchus cannula, an plugging device catheter, a plugging device multi-channel connector, an antifouling visual suite, a (wireless / wired) visual handle, a display device and a video connecting line, the insertion end of the bronchial cannula is provided with an administration suction port; a tube body of the bronchial cannula is of a double-hollow design; the device integrates the plugging bronchial cannula, the visible tube core and video image transmission and display into a whole, and the operation problems that blind insertion is conducted in an occluding operation in the past clinic, the occluding position is judged by listening to sound, and displacement of the plugging device in the operation cannot be found in time are solved. The problems of visual positioning of the plugging device, visual monitoring while oxygen supply in the operation, prevention of displacement of the plugging device in the operation and cross infection of doctors and patients, and plugging operation suitable for adult and child patients are thoroughly solved. And the operation safety is ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a novel occluder that can be positioned visually for occlusion of the lower bronchus and can be visualized and observed at any time during the operation. Background technique [0002] During lung surgery, it is usually necessary to occlude one side of the lung and supply oxygen to the other side to maintain vital signs. Currently, thicker double-lumen tubes or bronchial occluders are used on the market. Both medical devices are blindly inserted and then judged by listening to the lungs. The positioning is difficult, the operation time is long, and the risk of displacement after intraoperative blockage is uncontrollable, and the operation risk is high. We designed a new type of occluder that can be positioned visually for lower bronchial occlusion and can be visualized at any time during the operation. Contents of the invention [0003] The purpose of the present invention is to ...
