TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to a disposable endoscope forceps and a use method thereof. BACKGROUND

[0002] Endoscopic surgery is widely used in clinical practice due to its minimal invasiveness and rapid recovery. Endoscopic forceps are key instruments in such surgeries, used for grasping, separating, biopsy or handling tissues. Traditional reusable endoscopic forceps have the risk of cross-infection due to incomplete cleaning and disinfection, performance degradation (such as loose closure of the jaws, rotation failure) caused by aging, and high maintenance costs.

DETAILED DESCRIPTION

[0015] The technical solutions of the present application will be further described in detail below in combination with preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0016] Please refer to Figures 1-6 The present application provides technical solutions: disposable endoscope forceps and its use method, including endoscope assembly 1 and disposable endoscope forceps 2, endoscope assembly 1 includes soft tube 111, embedding groove 112, camera 113 and channel 114; The camera 113 is embedded in the embedding groove 112, the embedding groove 112 is opened at the left end of the soft tube 111, and the right side is connected with the line groove 115, the camera 113 is connected with the external display wire through the line groove 115, the channel 114 is opened in the inside of the soft tube 111, and is in the form of through; The disposable endoscope forceps 2 is inserted into the channel 114; The endoscope assembly 1 is first inserted into the human body, then the image inside the human body is collected by the camera 113, then the disposable endoscope forceps 2 is inserted into the channel 114, the image is collected by the camera 113, the image is displayed on the external display, which is used for observation, and then the tissue is clamped by the disposable endoscope forceps 2, which is simple to operate, safer, and the soft tube 111 is variable, which has strong adaptability; The endoscope assembly 1 can be used continuously, only needs to be stored after disinfection, has simple overall structure, low manufacturing cost, is used more conveniently in cooperation with the disposable endoscope forceps 2, and is safer and more convenient for operation.

[0017] The inner wall left side of the channel 114 is fixed with the electromagnetic plate 116, the inside of the channel 114 is provided with the limiting plate 117, the front and back sides of the limiting plate 117 are integrally formed with the protruding blocks, and the protruding blocks are slidably connected in the channel 114; The spring 118 is arranged between the limiting plate 117 and the electromagnetic plate 116; When the disposable endoscope forceps 2 is inserted into the forceps channel 114 and reaches a certain position, it is blocked by the limiting plate 117, and then the disposable endoscope forceps 2 is continuously pushed, the forceps rod pushes the limiting plate 117 to move to the left side, and the spring 118 is deformed under stress, thereby slowing down the insertion speed of the disposable endoscope forceps 2, controlling the insertion speed, and greatly improving the safety of the operation to avoid discomfort of the patient caused by fast insertion speed.

[0018] The electromagnetic plate 116 is circuit-connected with the camera 113; The limiting plate 117 is made of magnetic metal material; When the camera 113 is running, the electromagnetic plate 116 is synchronously driven by electricity, and when the disposable endoscope forceps 2 pushes the limiting plate 117 through the forceps rod, it first receives the resistance of the spring 118, and at the same time, the electromagnetic plate 116 generates magnetic repulsion, thereby exerting resistance on the limiting plate 117. The resistance of the spring 118 plus the resistance generated by the magnetic force can further slow down the insertion speed of the disposable endoscope forceps 2, further improve the safety, and share the reaction force of the spring 118, thereby relatively prolonging the service life of the spring 118 and reducing the replacement cost.

Slowly advance the forceps so that the forceps head is close to the target tissue and perform the gripping and operation. Step S4: After extracting the tissue, a biopsy is performed; Step S5, Disposal: Dispose of the disposable endoscope forceps 2 in the designated sharps box or medical waste container. It provides a complete and standardized operating procedure, which greatly reduces the risk of instrument damage, tissue damage and endoscope damage caused by improper operation. The clear step-by-step guidance helps operators to quickly and accurately complete instrument preparation, introduction and operation, shortening the operation time. Through the correct use method, it gives full play to the performance advantages of the original design of disposable instruments, improves the biopsy success rate and operation satisfaction. From verification, use to disposal, the core principle of single use is emphasized throughout the process, which fundamentally eliminates cross-infection.
