[0041] In order to achieve flexible adjustment of the angle of the flush suction tube relative to the flush suction device body, the embodiments of the present application provide a flush suction device, comprising: a flush suction device body and a flush suction tube; a first connecting piece arranged at one end of the flush suction device body, the first connecting piece being provided with a first opening in communication with the inner cavity of the flush suction device body; a second connecting piece arranged at one end of the flush suction tube, the second connecting piece being provided with a second opening in communication with the inner cavity of the flush suction tube, the second connecting piece being rotatably connected with the first connecting piece; and a communication tube connected between the first opening and the second opening to make the inner cavity of the flush suction device body and the inner cavity of the flush suction tube in communication. The present application achieves the angle-adjustable connection of the flush suction tube relative to the flush suction device body through the rotatable connection of the first connecting piece and the second connecting piece, and forms a liquid passage by using the communication tube to communicate the inner cavities of the flush suction tube and the flush suction device body, so that the normal communication of the liquid passage between the flush suction tube and the flush suction device body can be maintained when the angle changes, and the normal realization of the function of the flush suction device is ensured.

[0042] The structure of the flush suction device button assembly and the flush suction device in the specific embodiments will be described in detail below with reference to the accompanying drawings. It can be understood that the structure shown in the drawings and described below is only an example, and is not a limitation on the scope of protection of the present application. The same reference numerals in the drawings represent the same or similar structures, and thus repeated description thereof will be omitted.

[0043] As Figure 1As shown, an embodiment of the present application provides a flushing aspirator, comprising a flushing aspirator body 1 and a flushing suction tube 2, wherein the flushing suction tube 2 is connected to one end of the flushing aspirator body 1. A flushing button assembly 31 and a suction button assembly 32 are provided on the side of the flushing aspirator body 1. The flushing button assembly 31 is used to control the switch of the liquid passage between the flushing pipeline and the flushing aspirator body 1. The suction button assembly 32 is used to control the switch of the liquid passage between the suction pipeline and the flushing aspirator body 1. In order to achieve the connection between the flushing aspirator body 1 and the flushing suction tube 2 and the communication of the liquid channel, the flushing aspirator further comprises a first connecting member 4, a second connecting member 5 and a flexible connecting tube 6. The connecting tube 6 is, for example, a soft rubber tube or a plastic tube. The first connecting member 4 is provided at one end of the flushing aspirator body 1, and the first connecting member 4 is provided with a first opening 41 (shown in FIG. 1 ) which is connected to the inner cavity of the flushing aspirator body 1. Figure 6 The second connecting member 5 is provided at one end of the irrigation and suction tube 2. The second connecting member 5 is provided with a second opening 51 (shown in FIG. 1 ) which is in communication with the inner cavity of the irrigation and suction tube 2. Figure 8 The second connecting member 5 is rotatably connected to the first connecting member 4. The connecting pipe 6 is connected between the first opening 41 and the second opening 51 to connect the inner cavity of the irrigation aspirator body 1 with the inner cavity of the irrigation aspirator tube 2.

[0044] The irrigation suction tube 2 can be arranged relative to the irrigation suction device body 1 along Figure 1 The irrigation and suction tube 2 is swung in the direction of the middle arrow, thereby switching the angle of the irrigation and suction tube 2 relative to the irrigation and suction device body 1. Figure 2 The structure after the irrigation suction tube 2 is swung to one side relative to the irrigation aspirator main body 1 is exemplarily shown in the figure. By adopting the present application, when it is necessary to adjust the angle of the irrigation suction tube 2 relative to the irrigation aspirator main body 1, the second connecting member 5 rotates relative to the first connecting member 4 but still maintains the connection between the two, so that the irrigation suction tube 2 will not be separated from the irrigation aspirator main body 1. The connecting tube 6 can be optionally a flexible hose, so that the connecting tube 6 can be deformed as the angle of the irrigation suction tube 2 changes, and the irrigation aspirator can be kept working normally at various angles. Therefore, by adopting the irrigation aspirator of the present application, the angle between the irrigation suction tube 2 and the irrigation aspirator main body 1 can be flexibly switched without replacing the irrigation suction tube 2, so as to meet the needs of different surgical procedures and usage habits.

[0045] like Figure 3 and Figure 4As shown, the first connecting member 4 includes at least one first connecting portion 42, and the second connecting member 5 includes at least one second connecting portion 52, and the first connecting portion 42 and the second connecting portion 52 are rotatably connected. Optionally, the rotatable connection between the first connecting portion 42 and the second connecting portion 52 is achieved by a tooth-like structure, and the irrigation and suction tube 2 can be maintained in its current position when the angle of the irrigation and suction tube 2 is not adjusted. In this embodiment, the first connecting member 4 includes two axially symmetrically arranged first connecting portions 42, and the first connecting portion 42 is a first lug facing the second connecting member 5. The second connecting member 5 includes two axially symmetrically arranged second connecting portions 52, and the second connecting portion 52 is a second lug facing the first connecting member 4. A first tooth portion 421 is provided on the outer side of the first connecting portion 42, and the first tooth portion 421 includes at least one external tooth. A second tooth portion 521 is provided on the inner side of the second connecting portion 52, and the second tooth portion 521 includes a plurality of internal teeth, and the plurality of internal teeth are arranged circumferentially, and each external tooth is respectively embedded in an internal tooth. When the angle of the flushing and suction tube 2 relative to the flushing and suction device body 1 is switched, each outer tooth rotates relative to the inner tooth and re-embeds with another inner tooth. In this embodiment, the inner teeth and / or the outer teeth are elastic. For example, the outer teeth are elastic. When the inner teeth and the outer teeth rotate relative to each other, an external force that can overcome the elastic deformation force of the outer teeth needs to be applied. The outer teeth will be slightly deformed, making the relative rotation of the inner teeth and the outer teeth smoother. After the rotation stops, the elastic retention effect of the outer teeth can also maintain the stability of the engagement of the inner and outer teeth. In another alternative embodiment, a plurality of inner teeth can be provided on the inner side of the first connecting portion 42, and at least one outer tooth can be provided on the outer side of the second connecting portion 52, which also falls within the scope of protection of the present application. The number and arrangement of the inner and outer teeth can be selected and set as needed, and are not limited to those shown in the figures.

[0046] The first connecting member 4 and the main body 1 of the flushing aspirator can be integrally formed, or can be two parts that are separately formed and then fixedly connected to each other. Figures 5-7 As shown, the first connecting member 4 and the flushing aspirator body 1 are two components that are molded separately. The inner side of the first connecting member 4 is provided with an internal thread, and the outer side of the communication port 12 of the flushing aspirator body 1 is provided with an external thread 11, and the first connecting member 4 and the flushing aspirator body 1 are connected by threads. In another alternative embodiment, the outer side of the first connecting member 4 may be provided with an external thread, and the inner side of the flushing aspirator body 1 may be provided with an internal thread, or the first connecting member 4 and the flushing aspirator body 1 may be connected by interference fit or the like. The threaded connection between the first connecting member 4 and the flushing aspirator body 1 provides a higher connection stability between the first connecting member 4 and the flushing aspirator body 1, and the sealing of the liquid channel connecting the first connecting member 4 and the flushing aspirator body 1 is achieved by threaded fit, thereby avoiding liquid leakage at the connection.

[0047] The second connecting member 5 and the irrigation and suction tube 2 can be integrally formed components, or can be two components that are separately formed and then fixedly connected to each other. Figure 8 As shown, the second connecting member 5 and the irrigation and suction tube 2 are two separately formed parts, and the second connecting member 5 is away from one end of the irrigation and suction device body 1 ( Figure 8 The left end of the second connecting member 5) is sleeved on one end of the flushing and suction tube 2 ( Figure 8 On the outside of the right end of the middle flushing and suction tube 2), the second connecting piece 5 and the flushing and suction tube 2 are tightly matched to avoid liquid leakage at the connection.

[0048] like Figure 1 and 3 As shown, the first connecting member 4 is away from one end of the flushing aspirator body 1 ( Figure 3 The left end of the first connecting member 4 is sleeved on the outside of the connecting pipe 6. The second connecting member 5 is away from one end of the flushing and suction tube 2 ( Figure 3 The right end of the second connecting member 5 is sleeved on the outside of the connecting pipe 6. Figure 3 and Figure 6 As shown, a first step portion 43 is provided inside the first connecting member 4, and the first end of the connecting pipe 6 abuts against the step surface of the first step portion 43, and the axial relative position of the connecting pipe 6 and the first connecting member 4 is limited by the first step portion 43. Figure 3 and Figure 8 As shown, a second step portion 53 is provided inside the second connecting member 5 , and one end of the connecting pipe 6 is abutted against the step surface of the second step portion 53 , and the axial relative position of the connecting pipe 6 and the second connecting member 5 is limited by the second step portion 53 .

[0049] The above content is a further detailed description of the present application in conjunction with specific preferred embodiments, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be considered to fall within the scope of protection of the present application.
