Description

Technical Field

[0001] The utility model relates to the field of medical equipment accessories, in particular to a flanging device for an endoscope. Background Art

[0002] Endoscope refers to a device that enters the human body through various channels. It can enter the body through surgical incisions or other natural channels to observe the internal conditions of the human body. Endoscopes can be used to see lesions that cannot be shown by X-rays, so they are very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and develop the best treatment plan based on this. Some endoscopes also have therapeutic functions, such as cystoscopes, gastroscopes, colonoscopes, bronchoscopes, laparoscopes, etc. As the core accessory of endoscopes used in surgery, snake bone rubber is crucial to ensure the clarity of the endoscopic surgical field and the smooth progress of the operation. When the curved snake bone of the endoscope is inserted into the rubber sleeve, a dilator is needed to be used to flanging the rubber sleeve and put it on the curved snake bone. The dilator in the prior art expands the rubber sleeve by external force, so that the rubber sleeve can achieve the expansion effect and is inserted into the curved snake bone. When using an ordinary dilator to expand the rubber sleeve, it is easy to damage the rubber sleeve and there is also a risk of damage to other accessories of the curved part. The damaged rubber sleeve not only affects the surgical effect, but also may cause surgical failure and increase the risk to the patient. In addition, when using an ordinary dilator to expand the rubber sleeve, it is usually necessary to spend a lot of time manually to assemble and adjust the rubber sleeve, which not only wastes precious medical time, but also may cause inaccurate or unstable assembly due to human factors. In emergency surgery or urgent use, this inefficient assembly method may cause surgical delays or operational errors.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0033] like Figures 1 to 9 As shown, a flanging device for an endoscope is used for flanging a rubber sleeve 14, which includes an expansion cone head 1 for inserting the rubber sleeve 14, and a push rod 3 sleeved on the expansion cone head 1; one end of the expansion cone head 1 is sequentially provided with a guide rod 15 and a push rod positioning column 13 for inserting the push rod 3, and the guide rod 15 is provided with a plurality of cone head guide grooves 12 with inclined surfaces 16; one end of the push rod 3 is provided with a plurality of push rod arms 31 correspondingly inserted into the cone head guide grooves 12, and the push rod 3 can move axially on the push rod positioning column 13; wherein, the push rod 3 is sleeved on the push rod positioning column 13 and pushed in the direction of the rubber sleeve 14, so that the push rod arm 31 is inserted into the rubber sleeve 14 through the cone head guide groove 12, and the push rod arm 31 expands through the inclined surface 16 and pushes the rubber sleeve 14 to be flanging.

[0034] Specifically, Figures 1 to 9As shown, at least four cone head guide grooves 12 are provided on the guide rod 15, and the height of the inclined surface 16 gradually increases from the end close to the push rod positioning column 13 to the end away from the push rod positioning column 13. The push rod arms 31 are arranged at intervals at one end of the push rod 3. The push rod arms 31 and the push rod 3 are all integrated structures, and at least four push rod arms 31 are provided. In this embodiment, the material of the push rod 3 is plastic or metal, so that the four push rod arms 31 have deformation characteristics, and one end of any push rod arm 31 is provided with a push block 3 3. The inner cavity of the push rod 3 is provided with a push rod positioning groove 32, and the side surface of the push block 33 is a smooth arc surface. The push rod positioning groove 32 is sleeved on the push rod positioning column 13, so that the push rod 3 can move along the axis of the push rod positioning column 13; the four cone head guide grooves 12 are evenly distributed on the end of the guide rod 15 close to the push rod positioning column 13, and any inclined surface 16 is also provided with a low inclined surface and a high inclined surface, and the inclined surface height of the low inclined surface is less than the height of the high inclined surface, so that the inclined surface 16 forms a stepped inclined surface, and the push rod arm The push rod arm 31 is positioned and plugged with the cone head guide groove 12. Based on the deformation characteristics of the plastic or metal material, the push rod arm 31 can be bent and deformed, so that when the push rod 3 moves axially along the push rod positioning column 13 toward the end close to the expansion cone head 1, the push rod arm 31 is positioned and plugged with the cone head guide groove 12 and moves along the cone head guide groove 12 toward the end close to the expansion cone head 1. As the push rod arm 31 goes deeper into the rubber sleeve 14, the push rod arm 31 passes through the inclined surface of the cone head guide groove 12. The surface 16 gradually expands, and the expanded push rod arm 31 expands the rubber sleeve 14 through the push block 33 and causes the rubber sleeve 14 to be flanged. The combination of the plastic material and the inclined surface 16 can effectively reduce the risk of the push rod 3 breaking during the expansion process. On the other hand, the smooth arc surface of the push block 33 can not only help the rubber sleeve 14 to be flanged, but also effectively reduce the friction between the inner wall of the rubber sleeve 14 and the push rod arm 31, thereby reducing the damage to the rubber sleeve 14.

[0035] like Figures 1 to 9 As shown, the guide rod 15 is in the shape of a truncated cone, and the area of ​​one end of the guide rod 15 close to the push rod positioning column 13 is larger than the area of ​​the other end of the guide rod 15 close to the expansion cone head 1, and the area of ​​one end of the guide rod 15 close to the push rod positioning column 13 is larger than the area of ​​the push rod positioning groove 32; in this embodiment, the guide rod 15 can, on the one hand, limit the movement trajectory of the push rod arm 31 during use, and on the other hand, further limit the movement range of the push rod 3 in the push rod positioning column 13 through the end face of one end of the guide rod 15, effectively preventing the push rod 3 from moving too long and causing the push rod arm 31 to expand excessively and break, and further avoiding damage to the rubber sleeve 14 during expansion.

[0036] To further optimize this embodiment, Figures 1 to 9As shown, a cone head groove 11 is provided between the expansion cone head 1 and the guide rod 15, and a clamping ring 2 for fixing the rubber sleeve 14 is sleeved in the cone head groove 11, and the shape of the clamping ring 2 is C-shaped; in this embodiment, the rubber sleeve 14 is sleeved on the expansion cone head 1, and the clamping ring 2 is sleeved on the rubber sleeve 14 and clamped with the cone head groove 11, so that the rubber sleeve 14 is fixed on the expansion cone head 1 and the flange length of the rubber sleeve 14 on the expansion cone head 1 is fixed, which can effectively prevent the rubber sleeve 14 from falling off from the expansion cone head 1 during the expansion flanging process, avoid affecting the flanging effect, and enhance the use effect of this embodiment.

[0037] Working principle: align the push rod positioning groove 32 of the push rod 3 with the push rod positioning column 31, place the push rod arm 31 in the cone head guide groove 12, the rubber sleeve 14 is sleeved on the expansion cone head 1 and covers the cone head guide groove 31, the clamping ring 2 is sleeved on the rubber sleeve 14 and clamped with the cone head groove 11, push the push rod 3 into the rubber sleeve 14, the push rod arm 31 expands and pushes the rubber sleeve 14 to flanging.
