The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0019] The utility model provides an endoscope injection needle holder, such as Figure 1-4 As shown, it includes a storage mechanism 1, and an injection head 2 is slidably connected inside the storage mechanism 1.
[0020] It should be noted that, since the needle of the existing endoscopic injection needle holder is usually still outside the endoscope after the injection is completed, this may lead to the risk of secondary injury. In this solution, the piston 16 moves so that it drives the moving block 21 to move through the connecting buckle 17, thereby storing the needle 24 inside the accommodating tube 11, and the injection head 2 is fixed as a whole inside the accommodating tube 11 through the mutual connection between the positioning block 18 and the positioning groove 23.
[0021] Specifically, in this embodiment, this scheme mainly includes a storage mechanism 1, and the injection head 2 is slidably connected inside the storage mechanism 1. The driving rod 15 is driven to move, so that the driving rod 15 drives the piston 16 to approach the moving block 21, thereby discharging the medicine inside the accommodating tube 11 from the inside of the needle 24 to the inside of the accommodating tube 11 until the piston 16 and the moving block 21 are fitted with each other. When the piston 16 and the moving block 21 are fitted with each other, the connecting buckle 17 will be engaged with the inside of the card slot 22. At this time, the driving rod 15 is pulled, so that the driving rod 15 drives the moving block 21 to follow its movement through the connecting buckle 17. At this time, the positioning block 18 will be separated from the positioning slot 23, so that the needle 24 slides inside the connecting hole 14, and the needle 24 is stored as a whole into the accommodating tube 11.
[0022] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the storage mechanism 1 includes a accommodating cylinder 11, a protective cover 12 is fixedly connected to the outside of the accommodating cylinder 11, a sliding hole 13 is provided on the top of the accommodating cylinder 11, a connecting hole 14 is provided at the bottom of the accommodating cylinder 11, a driving rod 15 is slidably connected inside the sliding hole 13, a piston 16 is fixedly connected to the bottom of the driving rod 15, connecting buckles 17 are fixedly connected on both sides of the bottom of the piston 16, positioning blocks 18 are slidably connected on both sides of the inside of the accommodating cylinder 11, the piston 16 is slidably connected to the inside of the accommodating cylinder 11, and a spring is provided at the connection between the positioning block 18 and the accommodating cylinder 11. First, the moving block 21 is installed inside the accommodating cylinder 11 until the positioning groove 23 and the positioning block 18 are engaged with each other, and the driving rod 15 is driven to slide inside the sliding hole 13, and the drug is drawn into the accommodating cylinder 11 from its inside after passing through the injection head 2.
[0023] In a further preferred embodiment of the present invention, Figure 1-4As shown, the injection head 2 includes a moving block 21, and both sides of the top of the moving block 21 are provided with a slot 22, and both sides of the moving block 21 are provided with a positioning slot 23. The bottom of the moving block 21 is fixedly connected to a needle 24, and the needle 24 is slidably connected to the inside of the connecting hole 14. The inside of the slot 22 is engaged with the connecting buckle 17, and the inside of the positioning slot 23 is engaged with the positioning block 18. The driving rod 15 is driven to move, so that the driving rod 15 drives the piston 16 to approach the moving block 21, so that the medicine inside the accommodating cylinder 11 is filled. The object is expelled from the needle 24 into the accommodating tube 11 until the piston 16 and the moving block 21 fit together. When the piston 16 and the moving block 21 fit together, the connecting buckle 17 will fit into the inside of the card slot 22. At this time, the driving rod 15 is pulled, so that the driving rod 15 drives the moving block 21 to follow its movement through the connecting buckle 17. At this time, the positioning block 18 will be separated from the positioning slot 23, so that the needle 24 slides inside the connecting hole 14, and the needle 24 is stored in the accommodating tube 11 as a whole.
