Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multi-angle adjustable polyp removal device. Background Technology

[0002] With social development and the continuous improvement of people's living standards, gastrointestinal diseases caused by various reasons are very common, especially the number of patients with polyps has surged. Gastrointestinal polyps include colorectal polyps, gastric polyps, and small intestinal polyps, mainly referring to masses formed by localized hyperplasia of the digestive tract mucosa protruding into the lumen. Pathological types of gastrointestinal polyps are classified as inflammatory polyps, hyperplastic polyps, and adenomatous polyps, among which adenomatous polyps are precancerous lesions. With the popularization of endoscopic technology, the detection rate of gastrointestinal polyps is increasing year by year, and endoscopic polypectomy needs to be widely implemented to reduce the incidence of gastrointestinal tumors. The removal of gastrointestinal polyps requires the use of a polypectomy instrument, which is simple, convenient, and efficient to operate. Polyp removal instruments are mainly used for the removal of various polyps and excess tissues under endoscopy in conjunction with high-frequency electric shock. The most common type of polyp removal instrument is the snare, which is a device that uses a nylon rod to tighten a slip knot that has been pre-made with absorbable or synthetic sutures to ligate blood vessels, polyps or other ductal structures. It is easy to operate and has been applied to a variety of laparoscopic abdominal surgeries.

[0003] Most polyp removal instruments currently available cannot be adjusted at a single angle in terms of structure and operation. The angle can only be adjusted through endoscopy, which often fails to achieve the appropriate angle, making it impossible to snare and remove polyps more quickly and accurately.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] A multi-angle adjustable polyp removal device includes an outer tube 1. The outer tube 1 has a connecting groove inside, and a connecting wire 2 is slidably connected inside the connecting groove. A cutting ring 3 is located at one end of the connecting wire 2, and a control ring 4 is located at the end of the connecting wire 2 away from the cutting ring 3. The control ring 4 and the cutting ring 3 are located at opposite ends of the outer tube 1. The outer tube 1 also has an adjusting groove inside, and an adjusting wire 5 is slidably connected inside the adjusting groove. One end of the adjusting wire 5 is located on the outer surface of the cutting ring 3, and an adjusting ring 6 is located at the end of the adjusting wire 5 away from the cutting ring 3. Ring 6 abuts against the outer surface of outer tube 1. Cutting ring 3 has high elasticity and can be stored inside the connecting groove. The diameter of connecting wire 2 is larger than the diameter of adjusting wire 5. The inner diameter of connecting groove is much larger than the inner diameter of adjusting groove. There are two adjusting wires 5, which are evenly distributed on both sides of cutting ring 3 and are symmetrical to each other. There are two adjusting rings 6. The size of adjusting ring 6 is smaller than the size of control ring 4. A guide head 7 is provided at the top of cutting ring 3. The guide head 7 is V-shaped. Anti-slip textures are provided on the outer surfaces of adjusting ring 6 and control ring 4.

[0026] To enable convenient and rapid adjustment of the resection angle of this multi-angle adjustable polyp resection device, and to simplify its structure and improve work efficiency, as shown in the attached document... Figure 1-5 As shown, this application adopts the following structure. Through the coordinated arrangement of the adjusting ring 6, adjusting wire 5, cutting ring 3, connecting wire 2, and control ring 4, during use, after inserting the cutter along with the outer tube 1 to the corresponding polyp location, the relative position of the polyp and the cutting ring 3 is observed through an external endoscope. Subsequently, by pulling the adjusting ring 6, the adjusting wire 5 slides inside the outer tube 1, thereby pulling the cutting ring 3 to swing and adjust the position of the cutting ring 3 (in use, by controlling the adjusting ring 6 at different positions, different angles of swing of the adjusting ring 6 can be achieved, increasing the angle adjustment range), so that the position of the cutting ring 3 matches the position of the polyp. Then, by pulling the control ring 4, the connecting wire 2 slides inside the connecting groove, so that the cutting ring 3 covers the polyp and cuts it off. At the same time, it is stored in the outer tube 1, completing the polyp removal. This multi-angle adjustable polyp cutter has the effect of convenient and quick adjustment of the cutter angle and simplifies the cutter structure and improves working efficiency.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
