Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a bronchial occluder. Background Art

[0002] In thoracic surgery, lung isolation is often required to isolate the affected lung from the healthy lung, block the main bronchus on the affected side, and implement single-lung ventilation on the healthy side. Currently, the commonly used single-lung ventilation methods include double-lumen bronchial catheter method and bronchial blocker method. Compared with ordinary double-lumen bronchial catheters, bronchial blockers have the advantages of simple intubation and positioning, large effective lumen, complete lung isolation, and less physiological interference.

[0003] Reference is made to the authorized publication number "CN113974753B" which discloses a bronchial occluder, which records the technical problem that "the bronchial occluder is inserted through a straight tube, and when inserted to a bend, the tube body can be automatically bent by a driving member to achieve the bend. The entire intubation process is smooth and unobstructed, thereby improving the convenience of the intubation operation."

[0004] In the process of implementing the patent, the applicant found that the patent had the following technical problems:

[0005] Since the occluder set in the patent achieves the purpose of bending the end of the occluder by pulling a wire, but the direction of the end of the occluder cannot be determined after the occluder is inserted into the patient's lungs, when the end of the occluder is pulled by the pull wire, if the pulling direction is incorrect, the bent end of the occluder is easy to touch and squeeze the trachea, thereby causing damage to the inner wall of the patient's trachea. At the same time, only two pull wires are set in the patent, so the end of the occluder can only be bent in two directions, which will reduce the accuracy of the bending of the occluder. Therefore, it is necessary to propose a bronchial occluder to provide a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] As described in the background art, since the occluder provided in the patent achieves the purpose of bending the end of the occluder by means of a pulling wire, but after the occluder is inserted into the patient's lungs, the direction of the end of the occluder cannot be determined. Therefore, when the end of the occluder is pulled by the pulling wire, if the pulling direction is incorrect, the bent end of the occluder is likely to touch and squeeze the trachea, thereby causing damage to the inner wall of the patient's trachea. At the same time, only two pulling wires are provided in the patent, so the end of the occluder can only be bent in two directions, thereby reducing the accuracy of the bending of the occluder.

[0028] In order to solve this technical problem, the utility model provides a bronchial occluder, which can improve the accuracy of adjusting the end of the occluder by adding a pull wire, thereby making the end of the occluder more flexible, thereby reducing the damage of the tracheal inner wall by the end of the occluder.

[0033] When in use, the blocking component 1 is inserted into the patient's body through the patient's mouth, and a fiberoptic bronchoscope is also inserted to facilitate observation of the end of the blocking component 1 located in the patient's body;

[0034] By adjusting the setting of the adjustment component 4, the bending angle and bending force of the cuff 3 can be adjusted, and the accuracy of the bending of the cuff 3 can also be improved, so as to protect the inner wall of the patient's bronchus;

[0035] The flexible setting of the telescopic hose 2 can facilitate the adjustment component 4 to bend the cuff 3;

[0036] By setting the calibration component 5, the doctor can clearly know the direction in which the cuff 3 needs to be adjusted, avoiding the doctor to make adjustments by trial and error, thereby playing a certain protective role on the patient's bronchial inner wall.

[0037] The adjustment assembly 4 includes a first fixing ring 6 and a fixing plate 7. The first fixing ring 6 is fixedly connected to the outer side of the cuff 3 near one end of the telescopic hose 2. Four fixing plates 7 are fixedly connected to the outer peripheral side of the first fixing ring 6, and the four fixing plates 7 are arranged in a circular array.

[0038] The adjustment component 4 also includes a connecting line 8 and a limit plate 9. The fixing plate 7 is fixedly connected to one end of the telescopic hose 2 with the connecting line 8. A plurality of limit plates 9 are fitted in the gap outside the connecting line 8. The limit plates 9 are fixedly connected to the outside of the blocking component 1.

[0044] By setting the telescopic hose 2, when the connecting line 8 pulls the fixing plate 7 and the first fixing ring 6 to rotate, adaptive adjustment can be performed, so as to achieve the effect of adjusting the angle of the cuff 3, thereby facilitating the cuff 3 to accurately enter the trachea;

[0045] At the same time, by providing a plurality of connecting wires 8, the accuracy of adjusting the end of the occluder can be improved, thereby making the end of the occluder more flexible;

[0046] The plurality of limiting plates 9 can limit the connection line 8, so that the connection line 8 can be closely attached to the blocking component 1 when following the movement of the blocking component 1, thereby preventing the connection line 8 from scratching the inner wall of the patient's trachea and causing damage;

[0047] By setting the guide wheel 12, the smoothness of the connecting wire 8 can be improved when the connecting wire 8 is pulled, and at the same time, the outer side of the connecting wire 8 can be prevented from directly rubbing against the inner side of the hollow tube 11 and the second fixing ring 10, thereby improving the service life of the connecting wire 8.
