Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to an electronic ureteroscope structure. Background Art

[0002] A ureteroscope is a slender instrument consisting of a light-guiding fiber, a working lumen, and various working accessories for different purposes. It has a small diameter and is 35 to 45 cm long. Ureteroscopic surgery involves inserting a slender endoscope through the urethra, bladder, and ureteral orifice into the ureter, which is 0.2 to 0.5 cm in diameter. With the help of a television monitoring system, lesions within the ureter, such as stones and tumors, can be clearly observed, allowing for the diagnosis and treatment of ureteral diseases. A ureteroscope is a medical device used in urology. The use of a ureteroscope for the diagnosis and treatment of ureteral diseases has greatly improved the diagnosis and treatment of ureteral diseases, shortened patients' hospital stays, reduced treatment costs, and achieved satisfactory clinical results.

[0003] The lighting source and electronic camera of an electronic ureteroscope are generally integrated into an oblique mirror body of the ureteroscope. However, the existing oblique mirror body often suffers from short circuit damage to the internal electronic components due to the infiltration of external water flow. When the electronic components inside the oblique mirror body are damaged, it is not convenient to disassemble the oblique mirror body for repair.

[0004] In summary, there is a need for an electronic ureteroscope structure that is waterproof and easy to maintain and repair. Utility Model Content

The utility model provides an electronic ureteroscope structure with good waterproof effect and easy maintenance.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An electronic ureteroscope structure includes a mirror body, the rear end of which is provided with an infusion port, a water outlet, an instrument port, and an oblique mirror body, the front end of which is installed with a mirror tube, the inner side of which is provided with an operation channel, an observation channel, and an illumination optical fiber, the infusion port, water outlet, and instrument port are all connected to the operation channel, the inner side of the oblique mirror body is provided with a chamber, an inner wiring board is installed in the chamber, an illumination light source and an electronic camera are installed on the inner wiring board, the observation channel and the illumination optical fiber are both connected to the chamber, one end of the chamber is connected to the mirror body, and a waterproof block is installed at the other end of the chamber, and the waterproof block and the chamber are detachably connected.

[0008] By integrating the operating channel, observation channel, and illumination fiber into a single tube, the ureteroscope's compactness is improved, saving space. A waterproof block installed at the chamber port effectively prevents water from entering the chamber, preventing short-circuit damage to the electronic components within the chamber and improving the waterproofing of the oblique scope. The removable waterproof block and chamber design facilitate regular maintenance and repair of the electronic components within the chamber.

[0009] Preferably, the waterproof block is installed on the inner side of the chamber and the two are plugged into each other. A sealing ring 1 is sleeved on the outer wall of the waterproof block. The waterproof block and the chamber are sealed by the sealing ring 1, and an observation window is provided on the waterproof block. The connection method is simple and easy to operate, convenient for installation and disassembly, and reduces the difficulty of subsequent maintenance and repair. The design of the sealing ring 1 improves the sealing between the waterproof block and the chamber, and can effectively prevent external water from entering the chamber through the gap between the waterproof block and the chamber, resulting in a good waterproof effect. The design of the observation window allows staff to observe the working conditions of the electronic devices inside the chamber in real time, and to perform timely repairs when problems are found.

[0010] Preferably, the other end of the chamber is further provided with a sterilization cap, which is mounted outside the chamber port and plugged into the chamber port. Several sealing rings (II) are mounted on the inner sidewall of the sterilization cap, sealing the sterilization cap and the oblique mirror body via the sealing rings. During sterilization, the ureteroscope is sealed by placing the sterilization cap on the other end of the chamber, thereby improving sterilization efficiency and safety. The multiple sealing rings (II) seal the sterilization cap and the oblique mirror body, enhancing the seal between the two.

[0011] Preferably, the central axis of the instrument port, the central axis of the scope body, and the central axis of the operating channel are all located on the same straight line, thereby improving the working accuracy of the ureteroscope.

[0012] Preferably, the instrument port is located at the rear end of the main body, the water outlet is located on the left and right sides of the main body, and the infusion port and oblique mirror body are located on the upper and lower sides of the main body, respectively. The acute angle between the central axis of the infusion port and the central axis of the main body is 15° to 20°, and the acute angle between the central axis of the chamber and the central axis of the main body is 30° to 40°. By integrating the instrument port, water outlet, infusion port, and oblique mirror body into a single unit on the main body, the ureteroscope improves its structural compactness, saves space, and improves space utilization.

[0013] Preferably, the operation channel is located above the illumination fiber, and the illumination fiber is wrapped around the outside of the observation channel. The structure is compact, space is saved, and space utilization is improved.

[0014] The beneficial effects of the present invention are: improving the compactness of the structure of the ureteroscope, saving space, and improving space utilization; improving the waterproof effect of the oblique mirror body; improving the sealing performance; facilitating maintenance and repair; being able to observe the working conditions of the electronic components inside the chamber in real time, and being able to repair them in time when problems are found; improving the efficiency and safety of sterilization; and improving the working accuracy of the ureteroscope.
