[0017] The present invention provides a liquid drainage device for hysteroscopic surgery, which has the following beneficial effects:

[0018] 1. The present invention provides an extraction mechanism to extract body fluids in this way, thereby avoiding the problem that once a traditional straw is pressed against a wound in the body during operation, the wound is damaged due to negative pressure when the negative pressure in the hose and the liquid extraction connector is used to absorb the liquid. At the same time, it also avoids the situation in which the accumulated fluid is difficult to extract, thereby ensuring the stability of the extraction of body fluids in the patient's body and protecting the wound in the patient's body as much as possible.

[0019] 2. The present invention provides an extraction mechanism, and the opening of the opening slot is mostly blocked by the elastic plate, so that when absorbing the shallow water level effluent, the air entry is reduced, the negative pressure extraction is stable, and the problem that the shallow water level effluent cannot be extracted is avoided;

[0020] 3. The present invention sets an extraction mechanism. When a large amount of liquid needs to be extracted, the negative pressure strength can be increased to increase the negative pressure in the hose. Then the elastic plate bends toward the inside of the liquid extraction connector to open the opening of the opening groove, thereby increasing the liquid extraction area and improving the liquid extraction speed. In addition, the liquid can reduce the strong negative pressure in the hose during high-intensity liquid extraction by increasing the liquid extraction area, thereby avoiding the problem of damage to the affected area due to negative pressure once one end of the liquid extraction connector contacts the affected area during large negative pressure extraction.

[0021] 4. The present invention sets an extraction mechanism. After extracting more deep accumulated fluid with high intensity, when extracting the remaining shallow accumulated fluid, the negative pressure intensity in the hose is reduced, and the elastic force of the elastic plate and the elastic plate are used to naturally close the upper opening groove, thereby completing the stable extraction of shallow water level. The opening size of the opening groove can be freely controlled simply, quickly and conveniently to adapt to different working environments.

[0022] 5. The present invention sets an auxiliary mechanism and utilizes the rotation of the liquid extraction connector and the strip grooves on the liquid extraction connector to complete the movement of the liquid extraction connector deep into the effusion, and stirs the bottom layer of the effusion through the open grooves provided in the liquid extraction connector to complete the turning of the bottom layer of the effusion, so that the broken particles and waste at the bottom layer of the effusion are merged with the upper layer of the effusion, and then the negative pressure enters the liquid extraction connector and the hose, and is drawn into the liquid extraction machine, thereby completing the removal of the waste in the effusion and avoiding the impact caused by the waste at the bottom layer of the effusion adhering to the wound in the patient's body.

[0023] 6. The present invention provides an auxiliary mechanism. When the liquid extraction connector rotates, the liquid can achieve the effect of stirring the deeper effusion through the opening of the strip-shaped groove, so that the deeper effusion can be fully stirred and turned over, thereby improving the effect of turning over the waste in the effusion, and at the same time further reducing the impact of the waste on the patient.

[0024] 7. The present invention provides an auxiliary mechanism, and the opening of the pressure valve can ensure that once one end of the liquid extraction connector is in contact with the wound in the patient's body and the accumulated fluid is extracted under negative pressure, the negative pressure inside the liquid extraction connector increases, and the pressure valve will automatically open to complete the pressure relief, thereby reducing the degree of negative pressure damage caused by the liquid extraction connector being in contact with the mucous membrane in the patient's body due to improper operation of the staff, thereby ensuring the safety and health of the patient's wound as much as possible and avoiding the occurrence of unexpected situations during the operation.

Specific embodiments

[0038] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: A liquid drainage device for hysteroscopy surgery, including a liquid extractor 2, a hose 1 is fixedly connected to one side of the liquid extractor 2, and an extraction mechanism 3 is provided at one end of the hose 1;

[0039] The extraction mechanism 3 includes:

[0040] The bearing connection sleeve 301 is a circular hollow sleeve structure. The inner wall of the bearing connection sleeve 301 is fixedly connected to the outer wall of the hose 1. The outer wall of the bearing connection sleeve 301 is fixedly connected to the liquid extraction connector 302. The bearing connection sleeve 301 is used to connect the hose 1 and the liquid extraction connector 302.

[0041] The opening groove 304 is a rectangular groove, which is provided at one end of the liquid extraction connector 302. The opening groove 304 is used as a channel for the liquid extraction connector 302 to extract external liquid;

[0042] When in use, the hose 1 is inserted into the patient's body during hysteroscopic surgery, and the liquid extraction machine 2 is started to form negative pressure through the hose 1 to extract the liquid in the patient's body, thereby completing the drainage of the accumulated fluid in the affected area;

[0043] When one end of the hose 1 is inserted into the liquid and the liquid is discharged by using negative pressure, the liquid is sucked into the hose 1 through the liquid extraction connector 302 on one end of the hose 1, and the plurality of open grooves 304 provided at one end of the liquid extraction connector 302 allow the liquid to enter the liquid extraction connector 302 through the outside of the liquid extraction connector 302. The body fluid is extracted in this way, and the problem of the traditional suction tube being damaged by the negative pressure when the negative pressure is sucked in the hose 1 and the liquid extraction connector 302 once it is pressed against the wound in the body during operation is avoided. At the same time, the situation that the accumulated fluid is difficult to be extracted in this case is also avoided, thereby ensuring the stability of the body fluid extraction in the patient's body and protecting the wound in the patient's body as much as possible.

[0044] Example 2: Please refer to Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: a first elastic plate 305 is disposed on the inner wall of the opening groove 304, the first elastic plate 305 is an arc-shaped structure, and the first elastic plate 305 is a thin sheet structure.

[0045] There are six opening slots 304 and six first elastic plates 305 . The opening slots 304 and the first elastic plates 305 are evenly distributed on one side of the liquid extraction connector 302 .

[0046] The second elastic plate 307 is fixedly connected to the outer wall of the first elastic plate 305 . One end of the second elastic plate 307 is fixedly connected to one side of the opening slot 304 . The second elastic plate 307 and the first elastic plate 305 are elastic.

[0047] The outer wall of the first elastic plate 305 is provided with an arc groove 306, which is an arc-shaped groove. The number of the arc grooves 306 provided on the outer wall of the first elastic plate 305 is eight;

[0048] The opening of the open slot 304 is mostly blocked by the first elastic plate 305, so that when absorbing the accumulated liquid at a shallow water level, the entry of air is reduced, the stability of negative pressure liquid extraction is ensured, and the problem that the accumulated liquid at the shallow water level cannot be pumped out is avoided;

[0049] At the same time, when a large amount of liquid needs to be pumped, the negative pressure intensity can be increased, so that the negative pressure in the hose 1 increases. Then, the first elastic plate 305 on the open slot 304 will be easily bent due to its thinness and bend into the liquid extraction connector 302, opening the opening of the open slot 304, realizing an increase in the liquid extraction area to improve the liquid extraction speed. And by increasing the liquid extraction area, the strong negative pressure in the hose 1 during high-intensity liquid extraction is reduced, avoiding the problem that once one end of the liquid extraction connector 302 contacts the affected area during large negative pressure extraction, the affected area is damaged due to the negative pressure;

[0050] The arc-shaped groove 306 on the first elastic plate 305 can make the first elastic plate 305 bend more easily, reducing the problem that the first elastic plate 305 is difficult to bend due to the negative pressure inside the liquid extraction connector 302. At the same time, the second elastic plate 307 can pull the first elastic plate 305. When the negative pressure in the hose 1 decreases, the first elastic plate 305 can return to its natural position. When extracting the remaining shallow-position accumulated liquid after high-intensity extraction of more and deeper accumulated liquid, the negative pressure intensity in the hose 1 is reduced, and the first elastic plate 305 and the second elastic plate 307 use their elasticity to naturally close the open slot 304, completing the stable extraction of the shallow water level, and being able to simply, quickly and conveniently freely control the opening size of the open slot 304, so as to adapt to different working environments;

[0051] Embodiment 3: Please refer to Figure 1-12 , based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: An auxiliary mechanism 4 is provided on the outer wall of the first elastic plate 305. The auxiliary mechanism 4 includes a pressure valve 401. The pressure valve 401 is opened on the inner wall of the first elastic plate 305, and the number of pressure valves 401 opened on the outer wall of the first elastic plate 305 is four.

[0052] The pressure valve 401 is opened on the outer wall of the first elastic plate 305. The inside of the pressure valve 401 is communicated with the inside of the liquid extraction connector 302. A fixing block 402 is fixedly connected to one side of the first elastic plate 305, and the outer wall of the fixing block 402 is fixedly connected to the inner wall of the open slot 304.

[0053] A strip-shaped groove 403 is opened on the outer wall of the liquid extraction connector 302. The strip-shaped groove 403 is a rectangular groove, and the strip-shaped grooves 403 are evenly distributed outside the liquid extraction connector 302;

[0054] When the first elastic plate 305 is bent, one side of the first elastic plate 305 is fixed by the fixing block 402, so that the side away from the fixing block 402 is bent, and the accumulated liquid is sucked into the liquid extraction connector 302 through the bent side of the fixing block 402 during bending. Since the liquid enters the liquid extraction connector 302 from one side of the first elastic plate 305, a thrust is applied to the first elastic plate 305, so that the first elastic plate 305 drives the fixing block 402 and the liquid extraction connector 302 to rotate, and the liquid extraction connector 302 is rotatably connected to one end of the hose 1 through the bearing connecting sleeve 301, so the liquid extraction connector 302 is The bearing connection sleeve 301 is rotated on one end of the hose 1, and the pumping connector 302 is rotated and the strip groove 403 on the pumping connector 302 is used to move the pumping connector 302 deep into the effusion. The bottom layer of the effusion is stirred by the opening groove 304 provided on the pumping connector 302, so that the bottom layer of the effusion is turned over, and the broken particles and waste at the bottom layer of the effusion are allowed to merge with the upper effusion. Then, the negative pressure enters the pumping connector 302 and the hose 1, and is drawn into the liquid extraction machine 2, so that the waste in the effusion is removed, and the waste at the bottom layer of the effusion is prevented from being attached to the wound in the patient's body.

[0055] When the liquid extraction connector 302 rotates, the liquid can be moved through the strip grooves 403 to achieve the effect of stirring the deeper effusion, so that the deeper effusion can be fully stirred and turned up, thereby improving the effect of turning over the waste in the effusion, and further reducing the impact of the waste on the patient;

[0056] The opening of the pressure valve 401 ensures that once one end of the extraction connector 302 is in contact with the wound in the patient's body and the accumulated fluid is extracted under negative pressure, the negative pressure inside the extraction connector 302 increases, and the pressure valve 401 will automatically open to complete the pressure relief, thereby reducing the degree of negative pressure damage caused by the extraction connector 302 being in contact with the mucous membrane in the patient's body due to improper operation by the staff, thereby ensuring the safety and health of the patient's wound as much as possible and avoiding the occurrence of unexpected situations during the operation.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
