[0002] At present, during thoracic surgery, mediastinal surgery or cardiac surgery, in order to effectively perform lung isolation ventilation, a bronchial occluder is often required.

[0003] Nowadays, although the traditional occluder is smaller than the double-lumen tube, the damage to the airway is still not small. At the same time, with the use of a large number of patients, more and more complex airways have emerged, making the traditional occluder unable to meet the current requirements of a large number of applications and promotions. The requirements for the angle of the occluder for complex airways are increasing day by day. Therefore, a novel occluder is needed during the actual operation to cope with the complex and changeable airways. Summary of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] The present invention provides a novel angle-adjustable bronchial occluder, which includes:

[0032] A catheter 1, having at least one internal pipeline 114 and an external pipeline 113. The internal layer number is selected according to the needs of the operation. It can be two internal and external pipelines, or a design of multiple internal pipelines plus one external pipeline. The external pipeline is mainly used for the inflation and deflation operations of the occluding balloon.

[0033] An occluding balloon 2, provided at one end of the catheter, which is communicated with the external pipeline. An interface 12 is provided at the front end of the occluding balloon. The occluding balloon is made of silica gel material and will expand when inflated to occlude the corresponding trachea.

[0034] A multi-functional conversion joint 3, which has at least two branches, one of which is communicated with the internal pipeline. The multi-functional conversion joint is used to connect other functional pipelines.

[0035] A Y-shaped joint, which has at least two branches, one of which is communicated with the external pipeline, and the other branch is communicated with the internal pipeline. One branch is used to operate the occluding balloon, and the other pipeline can operate the bending control mechanism.

[0036] A bending control mechanism 11 is provided between the occluding balloon and the multi-functional conversion joint, and the bending control mechanism is arranged close to the occluding balloon. A dial 14 for regulating the bending degree of the bending control mechanism is also provided on the gas catheter.

[0037] A blocking and measuring thin passage 13 is also provided at the end of the catheter.

[0038] The bending control mechanism 11 includes:

[0039] A snake bone assembly 115 placed inside the gas catheter;

[0040] A connecting block 111, connected to one end of the snake bone assembly;

[0041] The drive wire 112 is placed in the inner pipeline, and one end of it is wound and connected to the dial, and the other end is connected to the connection block. When the dial rotates, the drive wire can perform a circumferential retraction action along the dial, thereby pulling the connection block connected to it and changing the bending degree of the snake bone assembly.

[0042] The connection block is located at one end where the snake bone assembly is connected to the blocking airbag, and thus the bending degree of the snake bone assembly is changed through the drive wire.

[0043] The bending control mechanism is used to realize the swing of the blocking airbag relative to the axis of the gas conduit.

[0044] The drive wire is made of titanium wire or silk thread of other materials, and is mainly used to drive the snake bone assembly to bend when the wire moves.

[0045] The branch of the Y-joint communicating with the outer pipeline is connected to the air extraction circuit.

[0046] The air extraction circuit includes an air extraction balloon 5, and the air extraction balloon is communicated with the branch of the Y-joint communicating with the outer pipeline. The air extraction balloon 5 is mainly used for inflating and deflating the blocking airbag.

[0047] The air extraction circuit is also provided with an inflation indicating balloon 4, which serves to indicate the inflation degree of the blocking airbag.

[0048] The snake bone assembly includes several annular bone segments, and each bone segment is hollow to form a docking cavity, and each docking cavity is connected end to end to form an instrument channel extending along the arrangement direction of the bone segments.

[0049] Inside the bone segment, a wire passing part is provided towards the docking cavity. A wire passing hole 116 is provided on the wire passing part, and the wire passing holes of each bone segment form a traction channel for inserting the drive wire, and the drive wire passes through the traction channel and is fixedly connected to the connection block on the other side.

[0050] The setting of the traction channel can limit the moving direction of the drive wire, so that it can better adjust the bending of the snake bone assembly. At the same time, the separate setting of the traction channel and the instrument channel can also avoid the mutual interference between the inserted instrument and the drive wire, reduce friction, increase the service life of the drive wire, and improve the operation efficiency and safety.

[0051] The snake bone assembly can refer to the snake bones of publicly disclosed patents such as the existing patent CN118252456A or CN117503026A, which belongs to publicly disclosed technology, so it will not be described in detail herein.

[0052] The dial is provided with scales in the circumferential direction, and the scales are angle values, and the bending angle can be directly determined through the scales, so as to perform angle adjustment more directly and clearly.

[0053] The embodiments should not be regarded as limitations to the present utility model, but any improvements made based on the spirit of the present utility model should fall within the protection scope of the present utility model.
