It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, the present invention provides a technical solution: a uterus cleaning tool comprises a tube body assembly 1, wherein the tube body assembly 1 comprises a long and thin suction tube 11, a hose 12 is sleeved on the outer side of the suction tube 11, a conical mounting head 13 is connected to one end of the hose 12 in a threaded mode, the mounting head 13 is connected to the outer side of the suction tube 11 in a sliding mode, a spring 14 and an expansion piece 15 are arranged between the suction tube 11 and the hose 12, the expansion piece 15 is arranged along the axial direction of the hose 12, and the uterus cleaning tool further comprises a tightening assembly 2 used for shrinking the diameter of the hose 12.

In the embodiment, when in use, firstly, the four bolts 22 are screwed forwards, the bolts 22 drive the pressure applying foot 23 to press the hose 12, so that the hose 12 is contracted on the outer wall of the suction pipe 11 to form a state with the smallest diameter, then the suction pipe 11 and the mounting head 13 are inserted into the vagina, the hose 12 is slowly inserted into the vagina, the external tightening component 2 is blocked by the vagina opening, the tightening component 2 is forced to slide on the outer wall of the hose 12 along with the continuous slow insertion of the hose 12, the four bolts 22 are reversely rotated along with the insertion of the hose 12 to drive the pressure applying foot 23 to be away from the outer wall of the hose 12, the control of the pressure applying foot on the hose 12 is released, the spring 14 in the hose 12 is not pressed and reversely expanded, the expansion piece 15 is pushed to move outwards to expand the hose 12 so as to open the inside of the vagina, then the suction pipe 11 is pushed to slide the suction pipe 11 deep into the vagina, then the suction device is clamped at the butt joint of the outer end of the suction pipe 11 and is started to suck intrauterine residues in the vagina, after the suction is finished, the four bolts 22 are screwed forwards, the hose 12 is squeezed and contracted until the minimum state is reached, and then the hose is sucked out of the vagina.

Furthermore, one end of the spring 14 is provided with a foot pad, and the foot pad is slidably connected to a sliding groove formed in the outer wall of the straw 11.

In the embodiment, the foot pad of the spring 14 slides in the sliding groove of the outer wall of the suction pipe 11, when the spring 14 supports the expansion piece 15 positioned at the outer side out, the diameter of the hose 12 is expanded, when the vagina is expanded, the suction pipe 11 is pushed into the vagina deep inside, the suction pipe 11 slides deeply, the foot pad of the spring 14 slides in the sliding groove of the outer wall of the suction pipe 11 to ensure that the original position is not moved, and the expansion range of the vagina is limited and is not too large, so the expansion distance of the spring 14 is not too long, and the phenomenon that the spring 14 bends or is misplaced due to left and right movement caused by too long extension does not occur during sliding.

Further, the other end of the spring 14 is fixedly connected to the inner wall of the expansion piece 15, and the outer wall of the expansion piece 15 is fixedly connected to the inner wall of the hose 12.

In the present embodiment, the spring 14 expands the expansion piece 15 around the inner straw 11 as a fulcrum to support and expand the outer tube 12, so that the tube 12 can open the vagina and the inner straw 11 can slide more deeply into the vagina.

Further, four sets of springs 14 and expansion pieces 15 are provided, and are circularly arranged between the suction pipe 11 and the flexible pipe 12.

In this embodiment, the four sets of springs 14 and the expansion pieces 15 in different directions expand the tube 12 uniformly and simultaneously in all directions, so that the entire tube 12 is expanded in diameter, but not in a single direction, to facilitate expansion of the vaginal inner diameter.

Further, the left and right ends of the expansion piece 15 are respectively provided with a spring 14, and the length of the expansion piece 15 is smaller than that of the hose 12.

In the present embodiment, the springs 14 are provided one on each of the left and right sides of the expanding piece 15, and the springs 14 expand the expanding piece 15 to increase the diameter of the tube 12, so that the tube 12 is directed to the vagina.

Further, the cross-section of the expansion piece 15 is arc-shaped and is adapted to the inner wall of the hose 12.

In this embodiment, the section of the expansion piece 15 is arc-shaped and is adapted to the inner wall of the flexible tube 12, so that when the expansion piece 15 is contracted or expanded, the flexible tube 12 is not damaged, and the external pressure foot 23 is also matched to clamp the flexible tube 12 and change the diameter of the flexible tube 12, so that the vagina is expanded by the expansion of the flexible tube 12, and then the internal suction tube 11 is conveniently inserted into a deeper position.

Further, the tightening assembly 2 includes a ring 21, a bolt 22 and a pressing leg 23, the ring 21 is sleeved on the outer wall of the hose 12, the bolt 22 is screwed on the ring 21, and the pressing leg 23 is rotatably connected to one end of the bolt 22.

In this embodiment, the outer side of the hose 12 is sleeved with the circular ring 21, and the installation positions are provided for the screw and the pressing foot 23, and then the pressing foot 23 below is driven to move by the rotation of the bolt 22, when the bolt 22 rotates forwards, the bolt 22 drives the pressing foot 23 to be away from the circular ring 21 to extrude the surface of the hose 12, otherwise when the bolt 22 rotates backwards, the bolt 22 drives the pressing foot 23 to be close to the circular ring 21 to pack up the surface of the hose 12, so that the hose 12 is expanded.

Further, four sets of the bolts 22 and the pressing legs 23 are provided, corresponding to the four sets of the springs 14 and the expansion pieces 15, respectively.

In the present embodiment, the four sets of bolts 22 and the pressing legs 23 are provided to compress the springs 14 and the expansion pieces 15 inside the tube 12 from four different directions, respectively, so that the diameter of the entire tube 12 is reduced, and the reduction of the tube 12 is more uniform in all directions in the four different directions, and does not deviate from the axis of the straw 11, thereby causing a deviation problem.

Further, the cross section of the presser foot 23 is arc-shaped, and is adapted to the expansion sheet 15, and is clamped between the inner side and the outer side of the hose 12.

In this embodiment, the arc pressurizing feet 23 are adapted to the arc expanding pieces 15, so that the expanding pieces 15 inside the hose 12 can be extruded from the outside, the expanding pieces 15 inside the hose 12 can be contracted, the diameter of the hose 12 can be contracted, the whole outside hose 12 can be reduced, the inside suction pipe 11 can be close to, and the original probe state can be formed.

Further, the end of the suction pipe 11 remote from the hose 12 is provided with a docking port for connection to an external suction device.

In this embodiment, the outer end of the suction tube 11 is provided with a butt joint for clamping an external suction device, so that the suction device and the suction tube 11 are butted, the suction force is guided to the inside of the vagina, and intrauterine residues in the vagina are sucked and are sucked out.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
