Specifically, the funnel barrel 3 is a structure similar to a long block, the rear end is a funnel-shaped opening on the outside, the center is a long through hole, and the other end is also arranged to be a funnel opening shape.

[0024] The valve placement cavity 32 runs through the front and back of the funnel tube 3, and the valve placement cavity 32 is connected to the stent funnel 31. The stent funnel 31 is used to place the endobronchial valve in the initial state. The stent funnel 31 is funnel-shaped. Before loading, the product is placed in the stent funnel 31 before being sold. When in use, it is pulled by the sleeve 5, and the inner wall of the funnel-shaped stent funnel 31 is contracted to be pulled into the valve placement cavity 32 to push the loading. Specifically, the sleeve 5 is connected to the valve and the base 1 placed in the valve placement cavity 32 through a traction device. That is, the valve stent is pulled by a detachable traction tool and the sleeve 5 is fixed to prevent it from falling off.

[0025] Preferably, the funnel tube 3 is transparent so that the internal valve can be easily seen, so that the doctor can check and determine the status and position of the valve before the operation. In addition, in order to ensure that it can be sealed during transportation and prevent the stent from being damaged, the base 1 is also provided with a rear upper cover 2. In order not to affect the doctor's inspection of the stent, the upper cover 2 is connected to the upper rear end of the base in a detachable manner, for example, it is clamped on the sleeve 5 or the base 1 by a snap connection.

[0026] In addition, the base 1 includes a funnel tube mounting groove 11 at the rear end and a sleeve mounting seat 12 at the front end. The funnel tube mounting groove 11 is in a groove shape, and the funnel tube part 3 is fixed in the funnel tube mounting groove 11. Specifically, it can be fixed by spring compression, which is convenient for fixing after the valve is installed, and is convenient for operation. A fixing spring 13 is arranged in the funnel tube part 3, and the two ends of the fixing spring 13 respectively abut against the end of the funnel tube part 3 and the funnel tube mounting groove 11.

[0027] Specifically, the sleeve mounting seat 12 is semi-cylindrical, and the upper surface of the sleeve mounting seat 12 is provided with a sleeve mounting groove 121 and a catheter placement groove 122. The catheter placement groove 122 is arranged at the center of the upper surface of the sleeve mounting seat 12, and the inner end of the catheter placement groove 122 is opposite to the outer end of the valve placement cavity 32. Among them, the catheter placement groove 122 is used to place the front end of the catheter used to transport the valve stent. In order to facilitate fixation, a mounting card slot can also be provided at a position close to the funnel barrel 3, and the front end of the main catheter can be clamped to facilitate the delivery of the stent into the catheter. As a preferred mode, the outer end of the valve placement cavity 32 is funnel-shaped, so as to facilitate the placement and alignment of the catheter. When loading, the front end of the catheter is placed in the funnel. The sleeve mounting groove 121 is used to install the sleeve 5, which can adopt a strip-shaped groove, slide with the sleeve 5, and the outer port is open to facilitate the detachment of the sleeve 5. An inner sleeve sliding groove 53 is provided inside the upper end of the sleeve 5 , and the inner sleeve sliding groove 53 is slidably connected to the sleeve mounting sliding groove 121 .

[0028] In order to facilitate the inspection and positioning during installation, a marking scale 33 is provided above the funnel tube 3 .

[0029] In addition, the sleeve 5 is limited on the base 1 by the sleeve safety lock line 51, and the sleeve safety lock line 51 passes through the through hole of the sleeve 5 and the through hole on the base 1. A valve pull line 52 is provided on one side of the sleeve 5, and the valve pull line 52 passes through the front end of the valve placed in the valve placement cavity 32. Specifically, two closed-loop wires are used, connected to the sleeve 5 and the bracket, and the bracket can be pulled into the predetermined position by pulling the sleeve 5. At the same time, another wire passes through the through hole on the base 1, and the limiting wire can be set at the end. The wire includes a redundant length, which is sufficient to ensure that the valve can be pulled to the predetermined position and that the sleeve 5 will not slip. After pulling the valve bracket, the two wires can be cut off separately with scissors to separate the sleeve 5.

[0030] For easy operation, a push rod 4 is provided on the side of the base 1, and the push rod 4 is fixed to the side of the base 1 through a push rod fixing frame 14. The push rod 4 includes a handle 41 and a long rod 42, and the handle 41 and the long rod 42 are integrally formed. The long rod 42 can be inserted into the valve placement cavity 32 to push the valve, and a through hole for the long rod 42 to pass through is provided at the rear end of the base 1. It is feasible that the push rod 4 is also sealed inside when the product is packaged. The fixing frame 13 can be a card slot structure, or it can be integrally injection-molded on the base 1, and the push rod 4 can be unscrewed when in use.

[0031] The working principle of the utility model is that when using, the push rod 4 is first removed, and then the upper cover 2 is removed to check whether the appearance of the loader is complete, the upper cover is opened, and the flap is checked to see if it has fallen off, and the sleeve 5 is pulled to the limit position where the line is the longest. At this time, the flap bracket is pulled and retracted into the flap placement cavity 32, and the sleeve 5 is restored to its original position. At this time, two lines are cut with scissors. In this embodiment, any one of the two top pull lines can be cut first, and then any one of the side pull lines can be cut, and finally the sleeve is detached. After detachment, check whether the flap is in the set position, place the front end of the delivery device, i.e., the delivery catheter, in the base card slot, and use the push rod to push the flap in the funnel tube into the tip of the delivery device, and the loading process is completed.
