Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a simple water sealing cap for a ureteroscope. Background Art

[0002] Ureteroscope is one of the most commonly used endoscopic instruments in urology. Its operating end is respectively provided with a water inlet hole, a water outlet hole and an operating hole. The operating hole can be respectively inserted with surgical devices such as lithotripsy forceps and laser optical fiber according to the requirements of the operation. At present, in order to prevent the water input from the water inlet hole during the operation from leaking from the operating hole, a water sealing cap is provided at the end of the operating hole. There is a hole in the center of the water sealing cap to facilitate the insertion of various operating instruments. However, the existing water sealing cap is not provided with an anti-leakage device, which often causes the water in the ureteroscope to leak through the water sealing cap, affecting the doctor's surgical operation. Therefore, it is important to provide a new simple water sealing cap to solve the above technical problems. Summary of the invention

[0003] The technical problem to be solved by the utility model is that the existing water sealing cap is prone to water leakage.

[0004] The technical solution of the utility model is as follows:

[0005] A simple water-sealing cap for a ureteroscope comprises a water-sealing cap body, a first instrument hole, a second instrument hole, and an anti-leakage device.

[0006] The water sealing cap is hollow cylindrical and made of rubber material with certain elasticity. There is an instrument hole 1 in the center of one end (due to the elasticity of rubber, the instrument hole cannot be observed with the naked eye). The instrument hole 1 is a passage for various surgical devices (such as stone removal forceps, laser optical fiber) to enter and exit. Due to the elasticity of rubber, the instrument hole 1 has a certain anti-leakage function.

[0007] The anti-leakage device is located inside the water-sealing cap body and is conical in shape. One end is fixed to the water-sealing cap body and the other end is open to the instrument hole 2, which is a passage for various surgical devices (such as lithotomy forceps and laser optical fiber) to enter and exit. The instrument hole 2 is made of tough rubber. Due to the elasticity of the rubber, the instrument hole 2 is closed under normal conditions. When an instrument passes through the instrument hole 2, it can fit the instrument well to prevent water leakage.

[0008] The beneficial effects of the utility model are:

[0009] 1. The utility model is designed with a double anti-leakage device to prevent water leakage in the ureteroscope body.

[0010] 2. The utility model is made of tough rubber, which can better create a closed environment and reduce water leakage in the ureteroscope.

[0011] 3. The utility model can be installed by itself, the device is simple, and can be used for a long time and multiple times. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a three-dimensional structural schematic diagram of the utility model.

[0013] Figure 2 It is a cross-sectional schematic diagram of the utility model.

[0014] Among them: 1. Water sealing cap body; 2. Instrument hole 1; 3. Instrument hole 2; 4. Anti-leakage device. DETAILED DESCRIPTION

[0015] In order to more clearly describe the specific use of the utility model, a preferred example is provided below, which is described in detail with the accompanying drawings. It should be noted that this embodiment is descriptive, not restrictive, and the protection scope of the utility model cannot be limited thereby.

[0016] like Figure 1-2 As shown, this embodiment provides a simple water sealing cap for ureteroscope, including a water sealing cap body 1, one end of which has an instrument hole 1, and the other end is connected to the ureteroscope. An inverted cone-shaped anti-leakage device 4 is connected inside the water sealing cap body 1, and the other end of the anti-leakage device 4 is an instrument hole 2.

[0017] The instrument hole 1 at one end of the water-sealing cap body 1 is a passage for surgical instruments to enter and exit. It is made of a tough rubber material. Under the naked eye, the instrument hole 1 cannot be observed due to the toughness of the rubber material, but the surgical instrument can open the passage and pass through. The other end of the water-sealing cap body 1 is also made of a tough rubber material and is connected to the ureteroscope. Due to the toughness of the rubber material, this end can be tightly connected to the ureteroscope. The water-sealing cap body 1 can be tightly connected to the ureteroscope to prevent water leakage in the ureteroscope body.

[0018] The anti-leakage device 4 is conical, with one end (the bottom of the cone) fixed in the water-sealing cap, and the other end (the top of the cone) opening in the instrument hole 2, which is the passage for surgical instruments to enter and exit. It is made of a tough rubber material. Under the naked eye, the instrument hole 2 cannot be observed due to the toughness of the rubber material, but the surgical instrument can open the passage and pass through. In addition, the instrument hole 2 can fit well with the surgical instrument. The anti-leakage device 4 has the function of further preventing water leakage in the ureteroscope.

[0019] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
