Detailed Description

The above-described aspects are further described below in conjunction with specific embodiments. It is to be understood that these examples are illustrative of the utility model and are not intended to limit the scope of the utility model. The implementation conditions used in the examples may be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are generally those in routine experiments.

In a specific embodiment, a controllable flushing device is provided, which comprises a handheld part 1 and a water inlet pipe 2, wherein the water inlet pipe 2 is communicated with the rear end of the handheld part 1, a flushing pipe 6 is communicated with the front end of the handheld part 1, a doctor holds the flushing device through the handheld part 1 when ureteroscope operation is performed, water is injected through the water inlet pipe 2, flows out of the front end of the flushing pipe 6, flushes the inside of a patient, and flushes blood and broken stone in the patient. Still be provided with drain pipe 5, drain pipe 5 intercommunication sets up in handheld portion 1 rear end to with negative pressure device intercommunication setting, after ending the washing operation to the patient, open negative pressure device, place sewage department in wash pipe 6 front end, attract the internal sewage discharge body through drain pipe 5, flow into the container that holds and connect sewage, guarantee doctor's operation field of vision is clear.

In order to meet the requirement that a doctor changes the flushing water pressure at any time according to the internal condition of a patient in operation, the device further comprises a pressure control valve 3, wherein the pressure control valve 3 is arranged on the water inlet pipe 2, the pressure control valve 3 is a foot control valve, and the communication closure of the water inlet pipe 2 and the water pressure inside the water inlet pipe 2 can be controlled by controlling the pressure control valve 3. When the pressure control valve is used, as a doctor needs to take surgical instruments and the handheld part 1 by both hands, the pressure control valve 3 is set as a foot control valve, so that the doctor can conveniently step on the pressure control valve at any time, the pressure control valve 3 is stepped on to enable the water inlet pipe 2 to be communicated with the flushing pipe 6 for flushing operation, the water pressure is adjusted by the degree of stepping on the pressure control valve 3, the pressure control valve is convenient to use, the operation of the doctor cannot be influenced, and the operation efficiency is improved.

In order to facilitate the doctor to observe the water pressure during flushing, the device further comprises a hydraulic gauge 4, wherein the hydraulic gauge 4 is arranged on a water inlet channel between the water inlet pipe 2 and the flushing pipe 6. When the doctor steps on the pressure control valve 3, the water pressure of flushing is also different, so the hydraulic pressure gauge 4 can intuitively observe the current water pressure of flushing, and the doctor can adjust the water pressure at any time. Two embodiments of the installation form of the hydraulic gauge 4 are available for selection:

in the first embodiment, the hydraulic gauge 4 is installed on the water inlet pipe 2, the specific installation position is that the pressure control valve 3 is on the water inlet pipe 2 of the hand-held part 1 section, the water flow adjusted through the pressure control valve 3 directly flows through the hydraulic gauge 4, and the hydraulic gauge 4 can display the water pressure in real time. In the second embodiment, the hydraulic gauge 4 is mounted on the hand-held part 1, and when the flushing operation is performed, a doctor can observe the numerical value of the hydraulic gauge 4 conveniently.

As a concrete embodiment that the water inlet pipe 2 and the water outlet pipe 5 are communicated with the hand-held part 1, a flow dividing piece 1.1 is communicated with the rear end of the hand-held part 1, the flow dividing piece 1.1 is of a three-way tubular structure, the flow dividing piece 1.1 is respectively communicated with the water inlet pipe 2 and the water outlet pipe 5, one-way valves are respectively arranged at the joints of the flow dividing piece 1.1 with the water inlet pipe 2 and the water outlet pipe 5, and the directions of the two one-way valves are opposite. By providing the flow divider 1.1 and by providing opposite directional check valves at both of the interfaces, interference between the inlet pipe 2 and the outlet pipe 5 during flushing and suction is avoided.

In order to avoid overlarge local water pressure during flushing, stones are soaked; or during aspiration, the stone fragments or blood clots block the wash tube 6, so that as a preferred embodiment of the wash tube 6, a side hole is provided at the end of the wash tube 6. During flushing, a part of water flow can flow out of the side holes, so that the flushing water flow is dispersed, and the water pressure of the water discharged from the front end of the flushing pipe 6 is reduced. At the time of suction, even if the end of the flushing pipe 6 is clogged with stone fragments or blood clots, sewage can be sucked into the drain pipe 5 through the side hole and discharged from the drain pipe 5.

Because only rely on the negative pressure device to attract the blood dirt, the suction magnitude is invariable, and the suction magnitude is different, and the effect of attracting the blood dirt is also different, so in order to be convenient for the doctor adjust suction magnitude in order to adapt to different operation conditions at any time, washing unit still includes imbibition valve 7, imbibition valve 7 installs on drain pipe 5 to the drainage channel of wash pipe 6. The suction valve 7 is provided in the drain passage, and can control the amount of suction force for sucking sewage and also control the connection or disconnection between the drain pipe 5 and the flush pipe 6. The suction valve 7 is shifted, the drain pipe 5 is communicated with the flushing pipe 6, sewage is pumped out of a patient body through the flushing pipe 6, the sewage is discharged out of the body through the drain pipe 5, and the drain pipe 5 is disconnected from the flushing pipe 6 when the suction valve 7 is loosened, so that water suction operation cannot be performed.

There are two specific embodiments of the suction valve 7:

in the first embodiment, the liquid suction valve 7 is a manual valve and is mounted on the hand-held part 1. The suction valve 7 is hinged on the handheld part 1, the drain pipe 5 of the suction valve 7 is stirred to be communicated with the flushing pipe 6 for suction, the suction valve 7 is continuously stirred, the communication degree between the drain pipe 5 and the flushing pipe 6 is gradually increased, and then the technical effect of gradually increasing suction is realized.

In the second embodiment, the liquid suction valve 7 is a foot control valve and is arranged on the drain pipe 5. The imbibition valve 7 is the automatically controlled valve and with negative pressure device communication connection, and the pipeline of drain pipe 5 passes imbibition valve 7, and through the degree difference of stepping on imbibition valve 7, sends the signal of telecommunication to the negative pressure device, makes the negative pressure device attract with different suction.

With the above-described preferred embodiments according to the present utility model as an illustration, the above-described descriptions can be used by persons skilled in the relevant art to make various changes and modifications without departing from the scope of the technical idea of the present utility model. The technical scope of the present utility model is not limited to the description, but must be determined according to the scope of claims.
