Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, and in particular to a waterproof sealing cap of a ureteroscope with a guide channel. Background Art
[0002] Ureteroscopy is a slender instrument consisting of a light-guiding fiber, a working cavity, and various working accessories for different purposes. The water seal cap is a working accessory that prevents the outflow of ureteroscope liquid. The current ureteroscope cap is usually a straight or I-shaped through-tube. When installed, it is usually directly inserted into the pipeline. The final fixing effect and sealing effect are poor. When the water pressure inside the pipeline is too high, water overflow is likely to occur, disrupting the stability of the water flow during treatment, interfering with the clarity of the surgical field, and thus affecting the surgical operation.
[0003] Moreover, during ureteroscopic surgery, when guide wires, laser optical fibers, occluders, stone removal baskets and other working tools are inserted through the sealing cap channel for surgical auxiliary operations, the channel of the water sealing cap itself is small and the channel diameter is fixed and cannot be expanded. The guide wires, laser optical fibers, occluders, stone removal baskets and other tools are relatively thin and difficult to operate, which increases the difficulty of insertion and affects the operating efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a waterproof sealing cap for a ureteroscope with a guide channel, which can solve the problem that the existing waterproof sealing cap has a small channel itself, resulting in difficulty in inserting tools such as guide wires and laser optical fibers, and ensure the sealing effect of the waterproof sealing cap itself and the stability of the connection.
[0005] In order to solve the above technical problems, the technical solutions adopted by the present utility model are as follows.
[0006] A waterproof sealing cap for a ureteroscope with a guide channel comprises an operating channel outer sheath, and both ends of the operating sheath channel are respectively provided with external threads; the front end of the operating sheath channel is threadedly connected to the front end connecting cap, and the other end of the front end connecting cap is threadedly connected to the ureteroscope channel; the rear end of the operating sheath channel is threadedly connected to an adjustable sealing cap; the tail end of the adjustable sealing cap is provided with a guide channel for guiding a guide wire, an optical fiber, etc. for easy insertion.
[0007] The above-mentioned waterproof sealing cap of a ureteroscope with a guide channel comprises a tapered portion and a straight portion connected to the tapered portion, wherein the outer end diameter of the tapered portion is greater than the inner end diameter of the tapered portion.
[0008] The above-mentioned waterproof sealing cap of the ureteroscope with a guide channel has a hollow rubber inner core installed inside the front end of the adjustable sealing cap to ensure sealing. One end of the rubber inner core is connected to the guide channel, and the other end of the rubber inner core is slidably installed inside the operating outer sheath channel.
[0009] The above-mentioned waterproof sealing cap of a ureteroscope with a guide channel, the rubber inner core is a T-shaped structure with a small front end diameter and a large rear end diameter, the rear end of the rubber inner core is installed in the central groove of the front end of the adjustable sealing cap, and the large diameter end of the rubber inner core can be inserted and matched with the inner wall of the operating outer sheath channel.
[0010] Due to the adoption of the above technical scheme, the technical progress achieved by the present invention is as follows.
[0011] The utility model provides a waterproof sealing cap for a ureteroscope with a guide channel. By arranging an adjustable sealing cap threadably connected to an operating outer sheath channel and a rubber inner core installed between the adjustable sealing cap and the operating outer sheath channel, the sealing of the operating channel can be adjusted in time, thereby avoiding the occurrence of water leakage and improving the stability of the channel connection. In addition, by arranging the guide channel, the insertion of tools such as guide wires, laser optical fibers, occluders, and stone removal baskets can be completed more quickly, thereby improving the operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the specific structure inside the utility model.
[0013] Among them: 1. outer sheath of operation channel, 2. front end connecting cap, 3. adjustable sealing cap, 4. rubber inner core, 5. conical part, 6. straight part. DETAILED DESCRIPTION
[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0015] A waterproof sealing cap for a ureteroscope with a guide channel, such as Figure 1 As shown, it includes an operating channel outer sheath 1, both ends of the operating outer sheath channel 1 are respectively provided with external threads, the front end of the operating outer sheath channel 1 is threadedly connected to the front end connecting cap 2, and the rear end of the operating outer sheath channel 1 is threadedly connected to the adjustable sealing cap 3.
[0016] A guide channel for guiding guide wires, optical fibers, etc. is provided at the rear end of the adjustable sealing cap 3, wherein the guide channel includes a conical portion 5 and a straight portion 6 connected to the conical portion 5, wherein the outer end diameter of the conical portion 5 is larger than the inner end diameter of the conical portion 5, so that guide wires, laser optical fibers, lithotripsy forceps, and other working tools that are difficult to insert can be introduced.
[0017] A rubber inner core 4 is installed inside the front end of the adjustable sealing cap 3 , one end of the rubber inner core 4 is connected to the guide channel, and the other end of the rubber inner core 4 is slidably installed inside the operating outer sheath channel 1 .
