DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present disclosure is further described below with reference to specific embodiments. It should be understood that these embodiments are merely used to illustrate the present disclosure rather than limiting the scope of the present disclosure. In addition, it should be understood that after reading the teaching of the present disclosure, those skilled in the art can make various changes or modifications to the present disclosure, and these equivalent forms also fall within the scope defined by the appended claims of the present disclosure.

[0021] As shown in FIG. 1, the present disclosure relates to a disposable angle-adjustable visual bronchial blocker, including a bronchial blocking catheter. The bronchial blocking catheter includes a stiff main catheter section 7 and a soft flexible section 3. Although hardness of the stiff main catheter section 7 is higher than hardness of the soft flexible section, the stiff main catheter section 7 can still be bent to a certain extent, thus keeping the shape and protecting interior lines while passing through the endotracheal tube. An inflatable air bag 2 is arranged on an outer side of the flexible section, a camera assembly 1 is arranged at a front end of the flexible section. An interior of the bronchial blocking catheter comprises a forward flexion control line 4, a backward extension control line 5, a ventilation lumen 6, an inflation line and a camera video line which are arranged in parallel in a direction of the bronchial blocking catheter. A control handle 14 is arranged at a tail end of the bronchial blocking catheter, and an angle control disk 15 for controlling a degree of bending of the soft flexible section 2 is arranged on a side face of the control handle 14. A front opening of the ventilation lumen 6 is formed in a front end face of the camera assembly 1, such that secretions in an airway can be sucked through the ventilation lumen 6.

[0022] As shown in FIG. 2, an interior of the angle control disk 15 includes a base, a top cover, a hollow rotating shaft, a forward flexion control line fulcrum 19, a backward extension control line fulcrum 20 and a control line fixer 21. The base is fixedly connected to the control handle 14, the hollow rotating shaft 18 and the angle control disk 15 are concentric, an end of the hollow rotating shaft 18 is rotatably connected to the control handle 14, and another end of the hollow rotating shaft 18 is connected to the top cover. The forward flexion control line fulcrum 19 and the backward extension control line fulcrum 20 are fixed to the base and arranged relative to a center of the angle control disk 15. The control line fixer 21 is fixed to the top cover and arranged on a perpendicular bisector of a connecting line between the forward flexion control line fulcrum 19 and the backward extension control line fulcrum 20.

[0023] The forward flexion control line 4 and the backward extension control line 5 are arranged on side walls of two symmetrical sides of the bronchial blocking catheter, respectively. A front end of the forward flexion control line 4 is connected to a side of the camera assembly 1, and a tail end of the forward flexion control line 4, after passing through the hollow rotating shaft 18 of the angle control disk 15, bypasses the forward flexion control line fulcrum 19 to be connected to the control line fixer 21. A front end of the backward extension control line 5 is connected to an other side of the camera assembly 1, and a tail end of the backward extension control line 5, after passing through the hollow rotating shaft 18 of the angle control disk 15, bypasses the backward extension control line fulcrum 20 to be connected to the control line fixer 21.

[0024] Specifically, during use, the top cover of the angle control disk 15 can be rotated, and the top cover drives the control line fixer 21 to rotate around the hollow rotating shaft 18. If the top cover drives the control line fixer 21 to rotate counterclockwise, the forward flexion control line 4 is tightened while the backward extension control line 5 is loosened, such that the soft flexible section 3 of the bronchial blocking catheter can bend towards a forward flexion direction. Meanwhile, the camera assembly 1 rotates in the same direction, such that condition ahead can be seen clearly, and whether the bronchus is the one needing to be blocked is determined. Similarly, if the soft flexible section 3 needs to bend towards a backward extension direction, the top cover drives the control line fixer 21 to rotate clockwise. A rotation angle and a length of pulling can be specifically designed according to actual situation, the rotation angle is usually about 180. After a forward direction is confirmed, the bronchial blocker of the present disclosure is pushed into the bronchus to be blocked, then air is supplied through an inflating port 17, and the inflatable air bag 2 is started to complete blocking. As the front end camera assembly 1 is relatively closer to the inflatable air bag 2, a situation that the front end camera assembly enters lobar bronchus due to the blocker is too long is avoided, and influence of operation range during lung resection is avoided.

[0025] Further, a hard outer envelope 8 is arranged on an outer side of the stiff main catheter section 7, and the hard outer envelope 8 is made of PVC.

[0026] Further, a front end of the camera video line is connected to the camera assembly 1, and a tail end of the camera video line is connected to a video display 12 through a video connecting line 13.

[0027] Further, as shown in FIG. 3, a tail end of the ventilation lumen 6 passes through an outer opening 16 of the ventilation lumen at a tail end of the control handle 14, and is connected to a pressure safety valve 24 and an oxygen connecting port 25, such that oxygen can be continuously delivered to the lung in the operative side during the operation. Moreover, a certain continuous airway pressure is set to alleviate hypoxia caused by single-lung ventilation.

[0028] Further, as shown in FIG. 4, light sources 23 and a camera 22 are arranged on the front end face of the camera assembly 1. The light sources 23 are symmetrically arranged on both sides of the camera 22 and the ventilation lumen 6. Preferably, the light sources 23 are LED (light-emitting diode) light sources.

[0029] It should be emphasized that the length and diameter of the bronchial blocker are not limited by the schematic proportion of the schematic diagram, and can be adjusted according to the actual use situation.
