Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an endoscope transparent cap wiping device. Background Technology

[0002] In clinical practice, the emergence of transparent caps is related to the development and advancement of endoscopic mucosal resection. As endoscopic surgeries such as polyp removal, mucosal resection, and foreign body removal become increasingly common, a transparent cap is typically placed at the tip of the endoscope during endoscopic procedures. This cap serves to support, isolate, stabilize, and expand the operating space, facilitating intracavitary exploration, tissue placement, and removal.

[0003] When using an electrocautery knife to cut the mucosa, oil droplets are generated. These droplets adhere to the inside of the transparent cap, thus affecting the surgical field of vision. Because there are no specialized instruments for cleaning the transparent cap, medical staff must remove the endoscope from the body before cleaning it, impacting clinical efficiency.

[0004] To address this, we have improved the existing five-head endoscopic foreign body forceps by combining existing multi-head endoscopic foreign body forceps with clinical experience. We modified the guidewire end to a brush head with a wiping transparent cap and designed a leak-proof tube with a cotton layer at the end of the outer sheath. This allows the wiping device to be directly inserted into the endoscopic tube to wipe the transparent cap at the end without removing the endoscope. It also prevents oil droplets from sticking to the endoscopic tube wall. The structure is scientifically designed, easy to operate, and improves the clinical efficiency of endoscopic treatment. Utility Model Content

[0005] The purpose of this invention is to provide an endoscope transparent cap wiping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An endoscope transparent cap wiping device includes an outer sheath, an inner guidewire disposed inside the outer sheath, an operating handle for driving the movement of the inner guidewire at one end of the outer sheath, and a plurality of elastic outer guidewires connected to the inner guidewire at the other end of the outer sheath, with a brush head at the end of each elastic outer guidewire.

[0008] As a further preferred embodiment of this utility model: a leak-proof tube is threaded to one end of the outer sheath tube near the elastic outer guide wire, and a cotton layer is provided inside the leak-proof tube, so that the elastic outer guide wire and the brush head can be retracted into the leak-proof tube.

[0009] As a further preferred embodiment of this utility model, five elastic external guide wires are provided.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This transparent cap wiping device improves upon the traditional five-point foreign body forceps for endoscopes by replacing the multi-point guide wire forceps at the end with a brush head capable of wiping the transparent cap. This allows for easy cleaning of the transparent cap at the end of the endoscope without removing it from the patient, making it convenient to operate and improving the efficiency of endoscopic clinical treatment. Furthermore, by incorporating a leak-proof tube, the brush head, after wiping away oil droplets, can be stored inside the tube when the wiping device is removed from the endoscope. The inner cotton layer prevents oil droplets on the brush head from adhering to the endoscope tube wall. The design is scientific, reasonable, and highly practical. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0018] Please see Figure 1-4 This embodiment provides an endoscope transparent cap wiping device, including an outer sheath tube 1, an inner guide wire 2 disposed inside the outer sheath tube 1, an operating handle 3 for driving the inner guide wire 2 to move at one end of the outer sheath tube 1, and a plurality of elastic outer guide wires 4 connected to the inner guide wire 2 at the other end of the outer sheath tube 1, with a brush head 5 disposed at the end of the elastic outer guide wire 4.

[0019] Meanwhile, a leak-proof tube 6 is threaded to one end of the outer sheath tube 1 near the elastic outer guide wire 4. A cotton layer 7 is provided inside the leak-proof tube 6, and the elastic outer guide wire 4 and the brush head 5 can be retracted into the leak-proof tube 6; preferably, five elastic outer guide wires 4 are provided.

[0020] It should be noted that the outer sheath 1, inner guidewire 2, operating handle 3, and elastic outer guidewire 4 are conventional structures familiar to those skilled in the art, and their movement principle is the same as that of existing endoscopic multi-head foreign body forceps, which will not be described in detail in this application.

[0021] In addition, as a conventional operation that those skilled in the art can conceive of, the operating handle 3 can also be improved so that when medical staff press the operating handle 3, the inner guide wire 2 can rotate, driving the elastic outer guide wire 4 and multiple brush heads 5 to rotate and wipe when wiping the transparent cap, thereby improving the wiping effect. This design can be obtained through custom processing and is an existing conventional design, which will not be described in detail in this application.

[0022] like Figure 2 As shown, when it is necessary to wipe the transparent cap of the endoscope, simply insert the wiping device into the endoscope tube so that it reaches the transparent cap at the end of the endoscope. Control the operating handle 3 to extend the elastic external guide wire 4 and the brush head 5 out of the leak-proof tube 6. The elastic external guide wire 4 is spread open so that the brush head 5 is pressed against the inner wall of the transparent cap. The brush head 5 moves back and forth to complete the wiping of the inner wall of the transparent cap. Alternatively, the outer sheath tube 1 and the operating handle 3 can be manually rotated to rotate the brush head 5 and improve the wiping effect. This is the routine operation and will not be described in detail.

[0023] After wiping is completed, the brush head 5 is retracted into the leak-proof tube 6 by controlling the operating handle 3. The oil droplets on the brush head 5 will soak into the cotton layer 7, which can prevent the brush head 5 from contacting the endoscope tube wall when the wiping device is pulled out, thus avoiding the problem of oil droplets sticking to the endoscope tube wall.

[0024] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0025] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
