DETAILED DESCRIPTION

[0024] The embodiment of the utility model is further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the technical scheme of the utility model, but cannot be used to limit the protection scope of the utility model.

[0025] Example:

[0026] As Figures 1 to 7As shown, the utility model provides a novel design's disposable ureteral nephroscope, including a mirror body 11, mirror body 11 is the main body frame of whole equipment, mirror body 11 slender shape is to adapt to the physiological structure of human ureter and renal pelvis, can smoothly insert and reach kidney site, so that the doctor can check and treat target area without damaging surrounding tissue. The doctor controls the movement, rotation of mirror body 11 in patient's body and adjusts the angle of the front end of mirror body 11 by holding operating handle 21. At the same time, the illumination assembly is integrated in operating handle 21, and is connected with mirror body 11 through quick disassembly structure, which is convenient for separation treatment after use. The anti-skid lines on operating handle 21 can ensure that the doctor can stably hold operating handle 21 during operation, even if the hands sweat or are affected by other liquids, to ensure the safety of operation and avoid unnecessary harm to the patient due to the sliding of operating handle 21. The imaging assembly located at the front end of mirror body 11 includes a camera 31, an image transmission line and an anti-fog coating outside the camera 31; the camera 31 is used as a device for observing the internal condition, which is responsible for capturing image information inside the ureter and kidney. During the examination, the camera 31 can real-time shoot the shape of the pipe wall, whether there are stones, tumors or other pathological tissues, and convert these visual information into electrical signals to provide the most direct basis for subsequent diagnosis; the image transmission line undertakes the task of quickly, stably and accurately transmitting the image data obtained by the camera 31 to the external display device; the internal environment of human body is warm and humid, under this condition, ordinary camera is easy to form fog on the surface, which seriously affects the image quality. The anti-fog coating prevents this situation from happening, ensuring that the camera 31 can clearly capture images throughout the examination process, maintaining the reliability of imaging.

[0027] As Figure 4 shown, the illumination assembly of the disposable ureteral nephroscope includes a light source 41 and a light guide fiber 42, and the light source 41 provides sufficient illumination inside the ureter and kidney. The LED light source has the advantages of high brightness, low energy consumption, less heat generation and long service life. In the dark internal environment of human body, it can produce light of sufficient intensity to illuminate the examination area, so that the camera 31 can clearly capture images. For example, when examining the deep part of the renal pelvis, good illumination can allow the doctor to clearly see the details of the renal pelvis mucosa. The light guide fiber 42 efficiently conducts the light generated by the light source 41 to the channel at the front end of the mirror body 11. Its good light transmission performance ensures that the light can accurately reach the part that needs to be illuminated, providing a clear view for examination; the camera 31 can adopt an Olympus A2942A camera.

[0028] As Figure 3As shown, the working channel 62 of the disposable ureterorenoscope provides the necessary passage for the insertion of various medical instruments; the sealing valve 61 at the entrance ensures the smooth passage of medical instruments while effectively preventing the leakage of body fluids and gases. The lubricating coating on the inner wall reduces friction when the medical instrument moves in the channel; when inserting biopsy forceps or other instruments, the lubricating coating makes the insertion and removal of the instrument more smooth, improving the operation efficiency.

[0029] As shown in Figure 5 , 6 , the quick disassembly structure of the disposable ureterorenoscope is fixed by pressing the male plug 51 and the female socket 52 with the disposable buckle, which realizes the convenient connection of the scope 11 and the operating handle 21. This connection method ensures the normal use of the ureterorenoscope while facilitating the quick separation after use. After one-time use, medical staff can easily disassemble the scope 11 and the operating handle 21 for disposal, which meets the use requirements of disposable medical instruments. The wedge-shaped guide surface 53 is located at the junction of the two, which facilitates the separation of the scope 11 and the operating handle 21. When disassembly is needed, this wedge-shaped guide surface 53 provides convenience for separation operation, making it easier for medical staff to complete the disassembly process. The disposable buckle includes a clamping block 54 and a clamping groove 55, the clamping block 54 is arranged on the male plug 51, and the clamping block 54 and the male plug 51 are connected through a breakable piece 56, the clamping groove 55 is opened in the female socket 52, which ensures the firm connection of the scope 11 and the operating handle 21 before use, preventing accidental separation during the operation process. After use, the two can be easily disassembled by breaking the breakable piece 56, which also avoids the cross-infection problem that may be caused by secondary use.

[0030] As shown in Figure 7 , after the ureterorenoscope is used, the disassembly tool includes a handle 71 and a pry bar 72, which is used to assist in separating the scope 11 and the operating handle 21. Medical staff hold the handle 71 and use the pry bar 72 in cooperation with the wedge-shaped guide surface 53 to complete the disassembly work, which improves the efficiency of handling disposable medical instruments.

[0031] The specific use and role of this embodiment are:

[0032] In use, the medical staff first checks the integrity of the device. Then the mirror body 11 is slowly inserted through the urethra, along the urethra, bladder into the urethra. The operating handle 21 assists in controlling the direction and speed of insertion, and the anti-skid pattern ensures stable operation, and the bendable part can adjust the angle when encountering physiological bends or narrow places, reducing tissue damage. After the mirror body 11 reaches the target position, the LED light source 41 in the operating handle 21 illuminates the front end of the mirror body 11 through the light guide fiber 42. The camera 31 captures images in a bright environment under the protection of the anti-fog coating, and the images are transmitted to the external display device in real time through the high-speed data transmission line, so that the doctor can observe the inside of the ureter and kidney and judge whether there is a lesion. If further operation is needed, the working channel 62 can be used. The sealing valve 61 ensures that the internal environment of the human body is stable when the instrument is inserted. The lubricating coating on the inner wall of the working channel 62 makes the instrument operation smoother and reduces tissue damage. After use, the mirror body 11 and the operating handle 21 are separated through the quick disassembly structure male plug 51, female socket 52 and other related parts by using the disassembly tool including the handle 71 and the pry bar 72. The disposable buckle: the clamping block 54, the clamping groove 55 and the easy-to-break part 56 ensure that it cannot be assembled again after use, avoid cross infection, meet the medical waste treatment specification, and ensure medical safety.

[0033] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and it is obvious for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments.
