Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Also, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

The application provides a soft mirror water injection equipment of foot-operated ureter is united to quiet formula of dripping, and when the field of vision is clear, the quiet water injection that drips, when the field of vision is unclear, the operator adopts pedal pressurization water injection by oneself, and the water injection of oneself control does not need assistant's help, a single ureter soft mirror operation of accomplishing that can be better.

As shown in fig. 1 in particular, the ureter soft lens water injection device 10 according to an embodiment of the present application includes a liquid storage container 11, a pressurization pedal 14, and a water injection head 15, and further includes a first three-way pipe 121, a second three-way pipe 122, a third three-way pipe 123, a first water guide channel 131, a second water guide channel 132, a third water guide channel 133, a first check valve 161, a second check valve 162, and a third check valve 163. The first end 1211 of the first three-way pipe 121 is communicated with the water outlet of the liquid storage container 11, the second end 1212 is communicated with the water inlet of the first water guide channel 131, and the third end 1213 is communicated with the water inlet of the second water guide channel 132. The first end 1221 of the second tee 122 is communicated with the water inlet of the water injection head 15, the second end 1222 is communicated with the water outlet of the first water guide channel 131, and the third end 1223 is communicated with the water outlet of the third water guide channel 133. The first end 1231 of the third three-way pipe 123 is communicated with the pressurizing pedal 14, the second end 1232 is communicated with the water outlet of the second water guide channel 132, and the third end 1233 is communicated with the water inlet of the third water guide channel 133. The first check valve 161, the second check valve 162 and the third check valve 163 are respectively disposed on the first water guide channel 131, the second water guide channel 132 and the third water guide channel 133 to respectively ensure that water flow in the first water guide channel 131, the second water guide channel 132 and the third water guide channel 133 can only flow from the water inlet to the water outlet and cannot reversely flow back.

In one embodiment, the reservoir 11 may be a conventional static drip reservoir, such as a bottle or bag, that is hung in a high position to provide water flow by the automatic gravity of the water. The water injection head 15 is used for connecting with the water injection channel of the flexible ureteroscope and supplying water into the water injection channel of the flexible ureteroscope, and the specific connection mode is the prior art and will not be described in detail herein. The pressurizing foot pedal 14 is used to pressurize the water flow in the third water channel 133 to meet the specific needs of the operator. The pressurizing pedal 14 is generally composed of a chamber, a pedal, and a return spring, and the pressure is supplied by pressing the chamber by stepping on the pedal. The implementation of the booster pedal 14 is conventional and will not be described in detail herein. The first water guide channel 131, the second water guide channel 132 and the third water guide channel 133 are respectively implemented by, for example, one or more communicated plastic water introduction pipes. The first, second, and

third check valves

161, 162, and 163 may be disposed in the first, second, and third
