Under the communication action of the liquid guide tube between the sleeve 4 and the second fixed shell 30, the pressure of the liquid acts on the fixed rod 29 in the second fixed shell 30, so that the fixed rod 29 drives the parts connected by the first fixed ring 21, the rotating shell 23 and the like to move leftwards together, the rotating shell 23 moves leftwards to drive the third fixed block 33 to move together and stretch the tension spring 22, the upper third fixed block 33 gradually breaks away from the cooperation with the second limiting block 34, the rotating shell 23 moves leftwards to drive the second fixed block 31 to move close to the second fixed ring 32, and the through hole 24 always keeps communicating with the first liquid guide shell 27 in the process because the opening area of the port of the first liquid guide shell 27 is larger than that of the through hole 24.
when the second fixing block 31 contacts the second fixing ring 32, the second limiting block 34 releases the limit on the upper third fixing block 33, and the third fixing block 33 continues to move left along with the continuous rising of the liquid pressure, and the rotating shell 23 and the two third fixing blocks 33 rotate around the sleeve 4 and move left under the extrusion action of the grooves on the second fixing ring 32, so that the two first liquid guiding shells 27 are gradually separated from the communication with the through holes 24.
When the two first liquid guiding shells 27 are completely separated from the matching with the through holes 24, under the action of the water pump on the liquid inlet pipe 9, the pressure in the second fixed shell 30 is continuously increased, so that the rotating shell 23 is continuously rotated until the rotating shell 23 cannot move, at this time, the two second liquid guiding shells 28 are rotated to the upper side and are communicated with the adjacent through holes 24, namely, at this time, the right cavity of the first cavity 7 is communicated with the left cavity of the second cavity 8 through the adjacent second liquid guiding shells 28, namely, injected liquid flows out of the left cavity of the second cavity 8, the left cavity of the second cavity 8 is reversely dredged, liquid in the uterine cavity is mixed into the left cavity of the first cavity 7, then impurities such as liquid mucus flow in the left cavity of the first cavity 7, and the subsequent liquid reenters the right part of the second cavity 8 through the adjacent second liquid guiding shells 28 and is discharged from the liquid discharge pipe 10.
After the fluid flow in the uterine cavity is recovered to be normal, the fluid flow in the uterine cavity is reversely operated under the action of the tension spring 22, the third fixed block 33 which is rotated to the upper side at the moment is inserted into the second limiting block 34, the initial state is recovered, the fluid flow in the uterine cavity is reversely dredged to a certain extent by the operation, the first cavity 7 and the second cavity 8 are prevented from being blocked, the safety of a patient is indirectly protected, and discomfort caused by excessive expansion of the uterine cavity of an operator is avoided.
Example 3: based on embodiment 2, referring to fig. 5, 13 and 14, the device further comprises a pressure adjusting mechanism for changing the pressure of the liquid in the first chamber 7, the pressure adjusting mechanism is arranged on the side wall of the shell 1, the pressure adjusting mechanism comprises a second screw rod 35, the second screw rod 35 is in threaded connection with the front side surface of the shell 1, the right part of the sleeve 4 is in sliding connection with a sliding plate 36 in rotational connection with the second screw rod 35, the sliding plate 36 is inserted into the first chamber 7, a flow guiding component is arranged at the left part of the sleeve 4 and is used for changing the flow direction of the liquid in the uterine cavity, and the pressure in the first chamber 7 is adjusted by rotating the second screw rod 35, so that the liquid flow path in the uterine cavity is convenient to adjust subsequently.
Referring to fig. 13-15, the flow guiding assembly includes two third fixing shells 37 that are symmetrical in front and back, the two third fixing shells 37 are embedded in the left portion of the sleeve 4, the two third fixing shells 37 are respectively communicated with the first chamber 7 and the second chamber 8, a sliding plug 38 is slidably connected in each third fixing shell 37, an elastic piece 39 is installed between the sliding plug 38 and the adjacent third fixing shell 37, the elastic piece 39 is located in the adjacent third fixing shell 37, the sleeve 4 is embedded with three second conduits 40 that are uniformly distributed, the three second conduits 40 are respectively communicated with the two third fixing shells 37, the communication ports of the three second conduits 40 and the two third fixing shells 37 are linearly and uniformly distributed in the horizontal direction, the sliding plug 38 is matched with the adjacent second conduits 40, when the pressure in the first chamber 7 is increased, the sliding plug 38 is moved under pressure to release the shielding of the corresponding third fixing shells 37, the corresponding second conduits 40 are convenient for spraying mucus on the side wall of the uterine cavity, and the image recognition unit 5 is improved in scanning accuracy and comprehensive flushing of the uterine cavity.
After the uterine cavity is filled with liquid, an operator scans and records the uterine cavity by using the image recognition unit 5, when the adhesion mucus on the lateral wall of the uterine cavity affects the accurate scanning of the image recognition unit 5 on the lateral wall of the uterine cavity, the operator rotates the second screw rod 35 by properly rotating the second screw rod 35 to drive the sliding plate 36 to move towards the inside of the shell 1, namely the sliding plate 36 is gradually inserted into the sleeve 4, the sliding plate 36 moves to gradually increase the shielding of the flow cross section on the first cavity 7, and the liquid pressure in the first cavity 7 gradually rises at the moment because the suction pump on the liquid inlet pipe 9 keeps constant power.
in the process of gradually increasing the liquid pressure in the first chamber 7, since the elastic coefficient of the elastic piece 39 is smaller than that of the tension spring 22, at this time, the pressure change in the first chamber 7 does not enable the rotating shell 23 to move too much, but the pressure change enables the sliding plug 38 to retract into the adjacent third fixed shell 37, the sliding plug 38 moves to gradually release the shielding of the communication opening on the side wall of the adjacent third fixed shell 37, so that the liquid enters the third fixed shell 37 and is sprayed out of the corresponding second conduit 40 through the communication opening on the rightmost part of the third fixed shell 37, the sprayed liquid has the same irradiation direction as the image recognition unit 5, the sprayed liquid washes the inner wall of the uterine cavity to a certain extent, the release of mucus is accelerated, and the image recognition unit 5 is convenient for carrying out accurate scanning record on the inner wall of the uterine cavity.
The number of turns of the second screw rod 35 is increased, so that the depth of the sliding plate 36 inserted into the first chamber 7 is increased, the pressure in the first chamber 7 is increased, the moving distance of the sliding plug 38 in the third fixed shell 37 is controlled to be increased, the number of the second guide pipes 40 communicated with the first chamber 7 is increased, the impact area and the impact force of the ejected liquid on the inner wall of the uterine cavity are increased, the cleaning effect is improved, and after the cleaning is finished, the operator reversely rotates the second screw rod 35 to reset, so that the initial state is restored.
