[0006] The rear end of the flushing pipe is fixedly provided with a rotating head which is rotatably connected to the handle assembly through the rotating head;

[0007] The front section of the flushing pipe is provided with an arc-shaped arc section.

[0008] Compared with the previous technology, the beneficial effects of the utility model are:

[0009] 1. The flushing tube and the umbrella-shaped nozzle of the utility model can rotate together with the rotation of the rotating head. With the design of the arc segment, the working range of the flushing aspirator is wider, and the arc segment can also provide a certain support capacity for the organ.

DETAILED DESCRIPTION

[0022] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0023] like Figures 1 to 10 As shown, a multifunctional flushing and aspirating device comprises a nozzle assembly 11, a connecting rod assembly 12 and a handle assembly 13 connected in sequence front and back; the connecting rod assembly 12 is a flushing tube 121; the front end of the flushing tube 121 is connected to the nozzle assembly 11;

[0024] The feature is that: a rotating head 127 is fixedly disposed at the rear end of the flushing tube 121 and is rotatably connected to the handle assembly 13 through the rotating head 127;

[0025] The front section of the flushing pipe 121 is provided with an arc-shaped arc section 123 .

[0026] The structure of the arc segment 123 allows the flushing tube 121 of the flushing aspirator to present a certain curvature, and the rotation together with the rotating head 127 can make the working range of the flushing aspirator wider, and the arc segment 123 can also provide a certain support capacity for the organ.

[0027] The nozzle assembly 11 is a replaceable umbrella-shaped nozzle, which is detachably connected to the front end of the arc segment 123;

[0028] The umbrella-shaped nozzle is provided with a plurality of flushing ports, one of which 111 is provided at the front end of the umbrella-shaped nozzle; the other flushing ports 111 are arranged in a circular array around the axial direction of the umbrella-shaped nozzle on the side wall of the umbrella-shaped nozzle; each flushing port 111 is connected to each other, and each flushing port 111 is connected to the flushing pipe 121. The design of having a plurality of flushing ports can cover different positions around the cavity, further expand the working range, and ensure comprehensive cleaning.

[0029] The front end of the flushing pipe 121 is provided with an external thread structure 124, and the rear end of the umbrella-shaped nozzle is provided with an internal thread structure 112 that cooperates with the external thread structure 124. The threaded connection structure of the flushing pipe 121 and the umbrella-shaped nozzle is relatively conventional, so it will not be described in detail. Here, it is not limited to the threaded connection structure, and the threaded connection structure can also be replaced by a buckle connection structure.

[0030] The handle assembly 13 comprises:

[0031] The outer shell 131 serves as the main body of the handle assembly 13:

[0032] A connecting pipe 132 is disposed inside the outer shell 131, the front end of the connecting pipe 132 is connected to the rear end of the flushing pipe 121, and the rear end of the connecting pipe 132 is connected to a docking joint 133 for connecting to an external device; and

[0033] The button 134 is disposed on the side wall of the outer shell 131 and controls the connection of the connecting tube 132 .

[0034] The rear end of the flushing pipe 121 is provided with a flushing pipe joint 125, and the front end of the connecting pipe 132 is provided with a connector 136;

[0035] The flushing pipe 121 and the connecting pipe 132 are connected by a flushing pipe joint 125 and a connector 136. A button 134 is arranged on the connecting pipe and cooperates with the outer shell 131, and the flushing liquid is turned on and off by squeezing the button 134.

[0036] An annular connecting groove 126 is provided on the side wall of the flushing pipe joint 125;

[0037] The front end of the connector 136 is provided with an annular sheet 137 that cooperates with the annular connecting groove 126;

[0038] The outer periphery of the flushing pipe joint 125 is provided with a sealing ring 138, which is located behind the annular sheet 137. The sealing ring 138 is used to ensure the air tightness of the connection between the flushing pipe joint 125 and the connector 136, and plays a sealing role, that is, to ensure the air tightness of the connection between the annular connecting groove 126 and the annular sheet 137, thereby preventing the entire utility model from leaking liquid or gas.

[0039] A spring 135 for resetting the button 135 is disposed inside the button 134. The spring 135 is used to assist the button 134 in resetting.

[0040] To sum up, when the flushing aspirator is in use, the nozzle assembly 11 and the connecting rod assembly 12 are inserted into the human tissue through the established instrument channel, and then the flushing liquid is controlled by buttons to flush the inside of the tissue. If necessary, the rotating head is used to rotate the entire connecting rod assembly 12 and drive the nozzle assembly 11 to rotate together, thereby expanding the working range.

[0041] The flushing pipe 121 of the present invention can be made of plastic.

[0042] However, under specific requirements, the flushing tube 121 is also made of metal. If metal is used, an outer sleeve 122 is provided on the outer periphery of the flushing tube 121 , and the tail end of the outer sleeve 122 is connected to the rotating head 127 .

[0043] Generally speaking, the front end of the outer sleeve 122 will not extend to the front end of the flushing tube, that is, the front end of the outer sleeve 122 is at a certain distance from the front end of the flushing tube. If the outer sleeve 122 extends to the arc section 123 provided at the front end of the flushing tube 121, the corresponding part of the outer sleeve must also be arc-shaped.

[0044] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
