Technical Field
[0001] The present application relates to a medical device, and particularly to a flexible ureteroscope irrigator. Background Art
[0002] Flexible ureteroscopes are commonly used in urology for upper urinary tract examinations and minimally invasive transurethral lithotripsy surgeries. As Figure 1 shown in the basic structure of a flexible ureteroscope, it includes a handle 11 and a flexible tube 12. Among them, the flexible tube 12 is the part to be inserted into the ureter. Its lumen is small, and the material is polyurethane. The flexible ureteroscope needs to be cleaned and then disinfected after each use for the next use.
[0003] Currently, a 20 ml syringe is usually used for irrigation clinically. Clear water is aspirated into the syringe and then injected into the fiber insertion tube of the flexible ureteroscope to wash the inside of the tube. Due to the small lumen of the flexible tube, the irrigation process is relatively slow, and it takes a lot of time to aspirate clear water for irrigation. In addition, when manually injecting the syringe, attention needs to be paid to the injection pressure. If the pressure is too high, it is also easy to cause deformation of the flexible tube.

[0021] Hereinafter, the flexible ureteroscope flusher of the present application will be described in detail with reference to the accompanying drawings.
[0022] The flexible ureteroscope flusher of the present application includes: a first box body 20, a second cylinder body 30, and a cover body 40.
[0023] The first box body 20 is used to hold the cleaning liquid; the upper end of the first box body 20 is open, and a first hole is formed on the side wall of the first box body 20; the first hole is closed by a first rubber film 21; a first round hole is formed on the first rubber film 21; the first round hole is located at the lower part of the first box body.
[0024] The lower end of the second cylinder body 30 is closed by a bottom plate; the upper end of the second cylinder body 20 is open; a support platform 31 protruding upward is arranged at the central position of the bottom plate; the support platform 31 is used to horizontally place the handle 11 of the flexible ureteroscope 10; a space 34 for accommodation is formed between the support platform 31 and the peripheral wall of the second cylinder body 30; a second hole is formed on the peripheral wall of the second cylinder body 30; the second hole is closed by a second rubber film 33; a second round hole is formed on the second rubber film 33.
[0025] The cover body 40 is used to be threadedly combined with the upper end of the second cylinder body 30 to hermetically seal the upper end opening of the second cylinder body 30; an air pump 50 is installed on the upper part of the cover body 40; the air inlet channel of the air pump 50 passes through the cover body and communicates with the lower part of the cover body; the exhaust channel of the air pump is located above the cover body; a seal is formed between the air inlet channel of the air pump 50 and the cover body 40.
[0026] The free end of the flexible tube 12 of the flexible ureteroscope 10 passes out of the second cylinder body 30 through the second round hole, and then is inserted into the first box body 20 through the first round hole and immersed in the cleaning liquid; the diameters of the first round hole and the second round hole are smaller than the outer diameter of the flexible tube 12, so as to be tightened on the outer periphery of the flexible tube 12 to form a seal.
[0027] A recessed part 32 corresponding to the shape of the handle 11 of the flexible ureteroscope 10 is formed on the top side of the support platform 31 to stably support the handle 11.
[0028] The support platform 31 is integrally formed with the bottom plate of the second cylinder body 30. In another embodiment, the support platform 31 is a discrete device, which is convenient for taking out the support platform.
[0029] During use, open the cover body, as Figure 3Install the flexible ureteroscope on the flexible ureteroscope flusher of the present application as described above, insert the free end of the hose into the first box body; the handle is accommodated in the second cylinder body and located on the support platform. The first box body and the second cylinder body maintain a predetermined distance so that the hose is as straight as possible, and thus the resistance in the hose is relatively small. After covering the cover body, the air pump can be turned on first for suction to form a negative pressure in the second cylinder body. Under the action of the negative pressure, the air in the first box body is sucked along the hose into the second cylinder body, forming the flow of air in the internal pipeline of the flexible ureteroscope to conduct airflow cleaning on the internal pipeline first; then pour a predetermined amount of cleaning liquid into the first cylinder body; after the cleaning liquid is sucked into the internal pipeline, it flows out from the handle end and enters the accommodation space, thereby conducting liquid flow cleaning; when the liquid level in the first box body drops to the lower side of the free end of the hose, there is no longer liquid flow, and air re-enters the hose, and the re-flow of the airflow serves to dry the internal pipeline.
