Double-cavity bronchial cannula locking structure

Abstract

The invention discloses a double-cavity bronchial cannula locking structure, which relates to the technical field of medical instruments. The double-cavity bronchial cannula locking structure comprises a connector, wherein the surface of the connector fixedly communicates with a right connecting tube, a left connecting tube and a lower connecting tube; the surface of the right connecting tube is provided with a locking cap; the right end of the right connecting tube is provided with a protective cap; the surfaces of the left connecting tube and the lower connecting tube are respectively provided with a rotating cap body; the surface of the connector is provided with a first through hole which is used for the rotating shaft to penetrate through and is rotationally connected with a fixed shaft of the rotating shaft; the surface of a conversion block is provided with a T-shaped channel; the surface of the rotating shaft is fixedly connected with a rotating handle; the right connecting tube, the left connecting tube and the lower connecting tube are all made of soft medical plastic; the surface of the connector is provided with an auxiliary component used for locking the rotating handle; an auxiliary component comprises a notch arranged on the surface of the connector; the inner wall of the notch is slidably connected with an abutting block; and the surface of the abutting block and the inner wall of the notch are jointly and fixedly connected with a spring. The double-cavity bronchial cannula locking structure has the effect of conveniently switching different conduction channels of the cannula.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-lumen bronchial intubation locking structure. Background technique [0002] In contemporary anesthesia, a variety of cardiothoracic and vascular operations require lung isolation techniques; the most common methods for achieving lung isolation techniques are the use of double-lumen endobronchial catheters, single-lumen endobronchial catheters, and single-lumen endotracheal catheters combined with bronchial occluders. Among them, the use of a double-lumen endobronchial tube and a single-lumen endotracheal tube combined with a bronchial occluder is currently the most commonly used technique for lung isolation. [0003] However, when the traditional intubation needs to close a certain passage, it needs to be clipped with a hemostat, which is very unfavorable for medical staff to operate.
