The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figure 1-Figure 8 As shown, the utility model provides a detachable and replaceable working joint, comprising: a replaceable gun head 3 and an active buckle 4 movably connected to the flushing gun; when the active buckle 4 moves to a first position, the replaceable gun head 3 passes through the active buckle 4 and is plugged into the flushing gun; when the active buckle 4 moves to a second position, the replaceable gun head 3 is locked in the flushing gun by the active buckle 4.

[0036] The replaceable gun head 3 and the flushing gun are detachably connected via an active buckle 4 . After the connection, the flushing gun can flush and suck back the surgical wound via the replaceable gun head 3 .

[0037] In a specific solution, a positioning block 3 - 1 is provided on the replaceable gun head 3 , a housing positioning notch 1 - 1 is provided on the housing 1 of the flushing gun, and a buckle positioning notch 4 - 1 is provided on the movable buckle 4 .

[0038] When the movable buckle 4 moves to the first position, the buckle positioning notch 4-1 is aligned with the housing positioning notch 1-1, and the positioning block 3-1 of the replaceable gun head 3 passes through the movable buckle 4 and is inserted into the housing positioning notch 1-1;

[0039] When the movable buckle 4 moves to the second position, the buckle positioning notch 4-1 is offset from the housing positioning notch 1-1, and the positioning block 3-1 of the replaceable gun head 3 is locked in the housing positioning notch 1-1.

[0040] The working joint provided by this solution only needs to replace different gun heads to easily operate different parts, including flushing and back suction. It not only solves the problem, but also reduces costs, saves energy and protects the environment; it also improves the efficiency of flushing.

[0041] In a specific implementation scenario, combined with Figure 2 and Figure 3 It can be seen that when the replaceable gun tip 3 needs to be installed, the movable buckle 4 is moved to the first position, that is, the movable buckle 4 is pushed from the bottom to the top. When it is pushed to the top, the buckle positioning notches 4-1 on both sides of the movable buckle 4 are aligned with the shell positioning notches 1-1 on both sides of the shell 1. At this time, the replaceable gun tip 3 is in a state of waiting to be installed.

[0042] Combination Figure 4 and Figure 5 It can be seen that the replaceable gun head 3 to be replaced and installed is inserted from the front of the housing 1, and the protruding positioning blocks 3-1 on both sides of the end of the replaceable gun head 3 will first pass through the buckle positioning notch 4-1 of the movable buckle 4, and then enter the housing positioning notch 1-1 in the housing 1. After the end of the replaceable gun head 3 is inserted to the bottom of the housing positioning notch 1-1, the housing 1 is fixed with the outer casing 1. Figure 6 and Figure 7 It can be seen that when the movable buckle 4 is pushed downward from top to bottom, the buckle positioning notch 4-1 of the movable buckle 4 is offset from the positioning block 3-1 of the replaceable gun head 3, and the movable buckle 4 seals the positioning block 3-1 in the positioning notch 1-1 of the shell and cannot be pulled out, so that the replaceable gun head 3 can be locked and fixed on the shell 1.

[0043] When disassembly is required, the movable buckle 4 is first pushed upward from the bottom, and the buckle positioning notches 4-1 on both sides of the movable buckle 4 are aligned with the housing positioning notches 1-1 on both sides of the housing 1. Then the replaceable gun head 3 is pulled out and replaced with a replaceable gun head 3 of another model and size. It should be pointed out that no matter how the model of the replaceable gun head 3 changes, the position, shape and size of the positioning block 3-1 remain unchanged, so that the adaptive connection with the housing 1 can be achieved.

[0044] Further solutions, such as Figure 2-Figure 5 As shown, a flushing channel 5 and a back-suction channel 6 are provided in the replaceable gun head 3. Specifically, the replaceable gun head 3 includes a flushing and suction tube sleeve, and the flushing channel 5 and the back-suction channel 6 are located in the flushing and suction tube sleeve. When the replaceable gun head 3 is plugged into the flushing gun, the flushing channel 5 is docked with the flushing pipe in the flushing gun, and the back-suction channel 6 is docked with the back-suction pipe in the flushing gun. Each replaceable gun head 3 has two channels, and the back-suction channel 6 is generally larger than the flushing channel 5, which can prevent blockage. The two channels extend out of the flushing and suction sleeve 2. When the replaceable gun head 3 is plugged into the flushing gun, the flushing channel 5 is docked with the flushing pipe in the flushing gun, and the back-suction channel 6 is docked with the back-suction pipe in the flushing gun. The channel can be made of rubber or plastic. When the channels are plugged in, a transition or interference fit is used to prevent side leakage.

[0045] Among them, the back-suction channel 6 and the flushing channel 5 are both hollow cylindrical channels, and the flushing channel 5 is located in the back-suction channel 6. This design makes the diameter of the back-suction channel 6 larger than the diameter of the flushing channel 5, prevents blockage, and saves space.

[0046] In a further solution, the irrigation and suction tube sleeve is stepped, and the diameter of the irrigation and suction tube sleeve decreases from the replaceable gun head 3 along the axis inward. This can ensure that the front end irrigation channel 5 and the back suction channel 6 work normally, and under the premise of ensuring limited space, as much redundant part as possible is removed, so that the front end is as small as possible to facilitate entering the wound in the human body.

[0047] In a further solution, grooves are provided on both sides of the housing 1 of the flushing gun, and protrusions are provided on both sides of the movable buckle 4; when the movable buckle 4 moves to the first position, the protrusion on one side cooperates and abuts with the groove on the same side; when the movable buckle 4 moves to the second position, the protrusion on the other side cooperates and abuts with the groove on the other side. In this embodiment, the movable buckle 4 can be naturally placed on the housing 1, or a slide groove can be provided at the end of the housing 1, and the movable opening slides back and forth in one direction in the slide groove. The protrusions at both ends can prevent excessive sliding, and can also ensure that the sliding of the movable buckle 4 between the first position and the second position is accurate.

[0048] In a further solution, the movable buckle 4 is placed at the end of the housing 1, the protrusions are located at the upper and lower sides of the movable buckle 4, and the grooves are located at the upper and lower sides of the housing 1 and correspond to the protrusions; under the action of gravity, the movable buckle 4 moves from top to bottom to the second position, so that the protrusion on the other side cooperates with the groove on the other side to complete the locking. By limiting the position of the protrusion to the upper and lower positions, it is convenient to be more tightly installed after completion, and prevent the replaceable gun head 3 from accidentally falling out due to free loosening.

[0049] Further solutions, such as Figure 8 As shown, the end surface of the housing positioning notch 1-1 and the end surface of the housing 1 are wedge-shaped surfaces 4-2 that cooperate with each other. The setting of the wedge-shaped surface 4-2 can effectively prevent the replaceable gun head 3 from falling due to loosening after the buckle is positioned and fixed. Among them, the wedge-shaped surface 4-2 can be the end surface of the housing positioning notch 1-1 and / or the end surface of the movable buckle 4.

[0050] The embodiment of the utility model further provides a flushing gun, including a flushing gun body, the flushing gun also includes the detachable and replaceable working joint as described above, and the replaceable gun head 3 is connected to the flushing gun body through an active buckle 4. A flushing pipeline and a back-suction pipeline are arranged in the flushing gun body, and when the replaceable gun head 3 is plugged in, the flushing channel 5 and the back-suction channel 6 in the replaceable gun head 3 are tightly connected with the flushing pipeline and the back-suction pipeline respectively, and then normal flushing and back-suction operations can be started.

[0051] The above description is only a preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
