[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A liquid drainage device for hysteroscopic surgery, comprising a liquid extraction machine, one side of the liquid extraction machine is fixedly connected to a hose, and one end of the hose is provided with an extraction mechanism; The extraction mechanism comprises: The bearing connection sleeve is a circular hollow sleeve structure, the inner wall of the bearing connection sleeve is fixedly connected to the outer wall of the hose, the outer wall of the bearing connection sleeve is fixedly connected to a liquid extraction connector, and the bearing connection sleeve is used to connect the hose and the liquid extraction connector; The open groove is a rectangular groove, and the open groove is opened at one end of the liquid extraction connector. The open groove is used as a channel for the liquid extraction connector to extract external liquid.

[0007] Preferably, an elastic plate is fixedly connected to the outer wall of the elastic plate, one end of the elastic plate is fixedly connected to one side of the opening groove, and the elastic plate and the elastic plate are elastic.

[0008] Preferably, an arc-shaped groove is provided on the outer wall of the elastic plate, and the arc-shaped groove is an arc-shaped groove. The number of the arc-shaped grooves provided on the outer wall of the elastic plate is eight.

[0009] Preferably, the outer wall of the elastic plate is provided with an auxiliary mechanism, and the auxiliary mechanism includes a pressure valve, and the pressure valve is opened on the inner wall of the elastic plate. The number of the pressure valves opened on the outer wall of the elastic plate is four.

[0010] Preferably, a pressure valve is provided on the outer wall of the elastic plate, the interior of the pressure valve is communicated with the interior of the liquid extraction connector, a fixed block is fixedly connected to one side of the elastic plate, and the outer wall of the fixed block is fixedly connected to the inner wall of the opening groove.

[0011] Preferably, the outer wall of the liquid extraction connector is provided with a strip-shaped groove, the strip-shaped groove is a rectangular groove, and the strip-shaped groove is evenly distributed outside the liquid extraction connector.

[0012] The present invention provides a liquid drainage device for hysteroscopic surgery, which has the following beneficial effects: 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.

[0013] 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; 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.

[0014] 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.

[0015] 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 accumulated fluid, and stirs the bottom layer of the accumulated fluid through the open grooves provided in the liquid extraction connector to complete the turning of the bottom layer of the accumulated fluid, so that the broken particles and waste at the bottom layer of the accumulated fluid are merged with the upper layer of the accumulated fluid, 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 accumulated fluid and avoiding the impact caused by the waste at the bottom layer of the accumulated fluid adhering to the wound in the patient's body.

[0016] 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.

[0017] 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.

DETAILED DESCRIPTION

[0020] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: a liquid drainage device for hysteroscopic surgery, comprising a liquid extraction machine 2, a hose 1 is fixedly connected to one side of the liquid extraction machine 2, and an extraction mechanism 3 is provided at one end of the hose 1; The extraction mechanism 3 comprises: 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. 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; 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; 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. Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: an elastic plate 305 is provided on the inner wall of the opening groove 304, and the elastic plate 305 is an arc-shaped structure and a thin sheet structure.

[0021] There are six opening slots 304 and six elastic plates 305 . The opening slots 304 and the elastic plates 305 are evenly distributed on one side of the liquid extraction connector 302 .

[0022] An elastic plate 307 is fixedly connected to the outer wall of the elastic plate 305 , one end of the elastic plate 307 is fixedly connected to one side of the opening slot 304 , and the elastic plate 307 and the elastic plate 305 are elastic.

[0023] The outer wall of the 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 elastic plate 305 is eight; Most of the openings of the opening slots 304 are blocked by the elastic plates 305, so that when absorbing the shallow water level effluent, the air entering is reduced, the negative pressure extraction is stable, and the problem that the shallow water level effluent cannot be extracted is avoided; At the same time, 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 1. Then, the elastic plate 305 on the opening groove 304 will bend toward the inside of the liquid extraction connector 302 because it is thin and easy to bend, opening the opening groove 304 to increase the liquid extraction area, thereby increasing the liquid extraction speed. In addition, by increasing the liquid extraction area, the strong negative pressure in the hose 1 during high-intensity liquid extraction can be reduced, thereby 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. The arc groove 306 on the elastic plate 305 can make the elastic plate 305 easier to bend, reducing the problem that the negative pressure elastic plate 305 inside the liquid extraction connector 302 is difficult to bend. At the same time, the elastic plate 307 can pull the elastic plate 305. When the negative pressure in the hose 1 decreases, the elastic plate 305 can naturally reset. After a large amount of deep effusion is extracted with high intensity, the remaining shallow effusion is extracted, and the negative pressure intensity in the hose 1 is reduced. The elastic force of the elastic plate 305 and the elastic plate 307 is used to naturally close the upper opening groove 304, so as to complete the stable extraction of shallow water. The opening size of the opening groove 304 can be freely controlled simply, quickly and conveniently, so as to adapt to different working environments. Example 3: Please refer to Figure 1-12 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an auxiliary mechanism 4 is provided on the outer wall of the elastic plate 305, the auxiliary mechanism 4 includes a pressure valve 401, and the pressure valve 401 is opened on the inner wall of the elastic plate 305. The number of the pressure valves 401 opened on the outer wall of the elastic plate 305 is four.

[0024] A pressure valve 401 is provided on the outer wall of the elastic plate 305 , the interior of the pressure valve 401 is communicated with the interior of the liquid extraction connector 302 , a fixing block 402 is fixedly connected to one side of the elastic plate 305 , and the outer wall of the fixing block 402 is fixedly connected to the inner wall of the opening groove 304 .

[0025] The outer wall of the liquid extraction connector 302 is provided with a strip groove 403, which is a rectangular groove and is evenly distributed outside the liquid extraction connector 302; When the elastic plate 305 is bent, one side of the elastic plate 305 is fixed by the fixed block 402, so that it bends away from the side of the fixed block 402. When bending, the accumulated liquid is sucked into the liquid extraction connector 302 through the bent side of the fixed block 402. Since the liquid enters the liquid extraction connector 302 from one side of the elastic plate 305, a thrust is applied to the elastic plate 305, so that the elastic plate 305 drives the fixed block 402 and the liquid extraction connector 302 to rotate. 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 connected to the hose 1 through the bearing connecting sleeve 301. The sleeve 301 is rotated on one end of the hose 1, and the rotation of the liquid extraction connector 302 and the strip groove 403 on the liquid extraction connector 302 are used to complete the movement of the liquid extraction connector 302 deep into the effusion, and the bottom layer of the effusion is stirred by the open groove 304 provided on the liquid extraction connector 302, so as 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 allowed to merge with the upper effusion, and then the negative pressure enters the liquid extraction connector 302 and the hose 1, and is drawn into the liquid extraction machine 2, so as to complete the removal of waste in the effusion, and avoid the influence caused by the waste at the bottom layer of the effusion adhering to the wound part in the patient's body; 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; 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.
