[0031] like Figures 2 to 4 As shown, the blocking assembly 5 includes a guide rod 51 movably connected to the guide hole 4, which can guide the guide rod 51 to move. One end of the guide rod 51 is fixedly connected to a push block 52, and the other end of the guide rod 51 is fixedly connected to a blocking block 53, and the blocking block 53 is arranged in an arc-shaped structure, which is convenient for limiting the bone wax and preventing it from falling. The outer wall of the guide rod 51 is connected to a first spring 54, one end of the first spring 54 is fixedly connected to the storage tube 1, and the other end of the first spring 54 is fixedly connected to the blocking block 53, which can generate a thrust on the pushing block 52, so that the pushing block 52 moves more stably and the bone wax is discharged one by one in sequence.

[0032] like Figures 2 to 4As shown, the linkage assembly 6 includes a linkage slide 61 movably arranged inside the guide groove 3, and the opposite surfaces of the linkage slide 61 are respectively provided with grooves 62, which are in close contact with the push block 52 and can limit the push block 52. One end of the linkage slide 61 is fixedly provided with a pressing cap 63, and the upper surface of the pressing cap 63 is provided with anti-slip grooves, which makes the finger pressing more stable. The other end of the linkage slide 61 is respectively provided with a slide groove 64, and the interior of the slide groove 64 is movably sleeved with a slide rod 65, which is fixedly connected to the inner bottom surface of the guide groove 3, and the outer wall of the slide rod 65 is sleeved with a second spring 66, one end of the second spring 66 is fixedly connected to the storage tube 1, and the other end of the second spring 66 is fixedly connected to the linkage slide 61, which can reset the linkage slide 61 to prevent multiple bone waxes from falling out of the interior of the storage tube 1.

[0033] Furthermore, a pressing block 8 is fixedly provided on the bottom surface of the pressing cap 63 , and the pressing block 8 is movably connected to the storage tube 1 , which can push the bone wax to move inside the storage tube 1 to avoid being stuck in the storage tube 1 .

[0034] Secondly, a card tray 9 is fixedly provided on the outer wall of the storage tube 1 to prevent the card tray 9 from falling when being taken out.

[0035] Furthermore, the outer wall of the storage tube 1 is sleeved with a rubber sleeve 10 to increase the friction between the storage tube 1 and the hand during the picking process, thereby increasing the stability of picking.

[0036] In addition, a receiving groove 11 is provided on the inner wall of the storage tube 1 to receive the blocking block 53 to avoid limiting the position of the bone wax.

[0037] Finally, the contact surfaces of the push block 52 and the groove 62 are tilted, so as to generate a thrust on the push block 52, so that multiple push blocks 52 move simultaneously and limit multiple bone waxes at the same time.

[0038] The operating principle of this embodiment is as follows: Before surgery, a cone of bone wax is placed into the storage cartridge 1 through the addition port 2. Subsequently, the pressing cap 63 is manually pressed, which drives the linkage slide 61 within the guide groove 3, which in turn drives the groove 62. The first spring 54 cooperates to push the push block 52 toward the groove 62, causing it to cling to the groove 62. The push block 52 then drives the blocking block 53 via the guide rod 51. When the blocking block 53 moves into the receiving slot 11, the bone wax inside the storage cartridge 1 falls downward to the space between the next blocking block 53.

[0039] After the bone wax falls between the next blocking block 53, the pressing cap 63 is released, and the second spring 66 pushes the linkage slide 61 to cooperate with the slide groove 64 and the slide rod 65, so that the linkage slide 61 is reset inside the guide groove 3, so that the linkage slide 61 drives the groove 62 to move, and the groove 62 pushes the push block 52 to move. The push block 52 pushes the blocking block 53 to reset through the guide rod 51, intercepting the fallen bone wax and preventing it from falling out from the bottom of the storage tube 1. Therefore, the bone wax is stored in the storage tube 1 in sequence.

[0040] After the bone wax is stored, during use, the pressing cap 63 is manually pressed to move the blocking block 53 into the receiving groove 11, so that a piece of bone wax falls from the lower end of the storage tube 1 onto the wound. This allows for quick and accurate placement of bone wax, reduces the number of operations required of operating room nurses to prepare small balls of gauze, saves time and effort, is more convenient, and avoids the risk of losing small balls of gauze, thereby increasing surgical safety.

[0041] The above specific embodiments are merely several optional embodiments of the present invention.
