Description of reference numerals: the valve comprises a valve body 1, a valve inner column hole 1-1, a notch 1-2, a water inlet interface 2, an instrument interface 3, a valve rod 4, a barrier strip 5, a tensioning bell mouth 6, a handle 7, a spherical bulge 8, a through hole 9 and a boss 10.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

the embodiment is as follows: as shown in attached figures 1-3, the detachable flushing water valve comprises a valve body 1, a valve inner column hole 1-1, a notch 1-2, a water inlet connector 2, an instrument connector 3, a valve rod 4, a barrier strip 5, a tensioning bell mouth 6, a handle 7, a spherical bulge 8, a through hole 9 and a boss 10. As shown in fig. 3, a water inlet port 2 (which can be used for externally connecting or discharging flushing fluid) and an instrument port 3 (which is used for connecting a surgical instrument) are arranged on the left side of the valve body 1 in the horizontal direction (i.e., the left-right direction in the drawing). An inner cylinder hole 1-1 of the valve is arranged in a vertical direction (namely, the vertical direction in fig. 3) of the valve body 1 in a penetrating way, and the water inlet interface 2 and the instrument interface 3 are respectively communicated with the inner cylinder hole 1-1 of the valve. Referring to the attached drawing 1, a valve rod 4 is detachably mounted on a valve inner column hole 1-1, a tensioning bell mouth 6 at the lower part of the valve rod 4 is matched and sealed with a lower opening of the valve inner column hole 1-1, and a boss 10 on the outer wall of the valve rod 4 is matched and sealed with an upper opening of the valve inner column hole 1-1. Referring to fig. 2, a through hole 9 is radially formed in the valve rod 4 between the boss 10 and the tensioning bell mouth 6 in a penetrating manner, and the through hole 9 can be used for communicating the water inlet interface 2 with the instrument interface 3. As shown in fig. 2, a handle 7 is transversely arranged at the upper part of the valve rod 4, and the handle 7 is used for driving the valve rod 4 to rotate along the inner wall of the valve inner column hole 1-1, so that the contact area between the opening part of the through hole 9 and the water inlet interface 2 and the instrument interface 3 is changed, and the water inlet and outlet amount is controlled.

As shown in fig. 3, preferably, a notch 1-2 is formed at the upper opening of the inner column hole 1-1 of the valve, a stop bar 5 is arranged at a position corresponding to the notch 1-2 on the outer wall of the valve rod 4, the stop bar 5 is used for stopping the notch 1-2, and when the valve rod 4 rotates, the stop bar 5 is stopped by two sides of the notch 1-2, so that the rotation within the angle between the two sides of the notch is limited.

Referring to fig. 2, preferably, the handle 7 is provided with three spherical protrusions 8 for preventing slipping during rotation. The expansion bell mouth 6 is provided with three split bell mouths which can be respectively matched with the lower openings of the column holes 1-1 in the valve for expansion, so that the sealing effect is achieved, and the disassembly is convenient. The instrument interface 3 is provided with external threads, so that the external connection of surgical instruments is facilitated.

As the preferred technical scheme, the valve rod 4, the barrier strip 5 on the valve rod 4, the tensioning bell mouth 6, the handle 7 and the spherical bulge 8 are all made of plastic materials, and can be easily detached, cleaned or replaced after the operation is finished.

The utility model discloses a working process: when the valve is used, the valve rod 4 is inserted along the direction of the inner cylinder hole 1-1 of the valve, the tensioning bell mouth 6 is tensioned at the lower opening of the inner cylinder hole 1-1 of the valve to realize sealing, and meanwhile, the boss 10 seals the upper opening of the inner cylinder hole 1-1 of the valve. In the operation, the contact area of the mouth part of the through hole 9, the water inlet interface 2 and the instrument interface 3 is changed by rotating the handle 7, and the water inlet and outlet quantity is further controlled. When the valve rod 4 rotates, the barrier strip 5 is blocked by two sides of the notch 1-2, so that the barrier strip is limited to rotate in an angle between two sides of the notch, excessive rotation is avoided, and the use safety and reliability are ensured. After the operation, the valve rod 4 can be detached for cleaning or replacement, so that the valve core is convenient and quick, and the valve core cannot be blocked by human tissue residues after the operation, so that the valve core is prevented from being blocked, and the water inlet and outlet amount is prevented from being blocked.

It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
