Description

Technical Field

[0002] Supine hypotension syndrome refers to low blood pressure and related symptoms that occur when a pregnant woman is in the supine position. This is a relatively common complication in cesarean section surgery. When a pregnant woman is in the supine position for surgery, the enlarged uterus will compress the inferior vena cava, reducing the amount of blood returning to the heart, which will lead to a decrease in cardiac output and a decrease in blood pressure. This will cause pregnant women to easily experience symptoms such as dizziness, nausea, vomiting, chest tightness, pale complexion, cold sweats, rapid pulse, palpitations, etc. The blood pressure of some people drops significantly, and the fetus is also affected, manifested as accelerated fetal heart rate, increased fetal movement, followed by a slow fetal heart rate, weakened fetal movement, and then acute fetal distress, which seriously affects the progress of the operation.

[0003] In this situation, we can usually improve the patient's symptoms by adjusting the patient's position, but the traditional surgical position placement method has some limitations. It is impossible to adjust the patient's position accurately and at multiple angles, and the tilt angle of the operating table is difficult to control accurately. An inappropriate angle will affect the surgical field of view and operational convenience, and it is difficult to prevent supine hypotension syndrome continuously and effectively.

[0032] The tilting assembly 207 includes a tilting worm 2071, a tilting seat 2072, a fixing block 2073, a tilting motor 2074, a tilting worm wheel 2075, and a power rod 2076; the rear end of the adjustment plate 210 is provided with a tilting seat 2072 fixedly connected to the tilting motor 2074; the front end of the tilting motor 2074 is provided with a tilting worm 2071 engaged with the tilting worm wheel 2075; both ends of the tilting worm 2071 are rotatably connected to the lifting ring 202; the front end of the tilting worm wheel 2075 is provided with a power rod 2076 rotatably connected to the tilting ring 204; the two ends of the power rod 2076 are symmetrically provided with fixing blocks 2073 fixedly connected to the bottom of the head pad 201;

[0033] The support assembly 4 includes support legs 401, side panels 402, a bottom plate 403, and a box body 404; the box body 404 is disposed on the upper end of the bottom plate 403, and the support legs 401 are disposed on the bottom; the side panels 402 are symmetrically disposed on both sides of the rear end of the box body 404;

[0034] In this embodiment, the working principle of the lifting component 208 is as follows: by starting the lifting motor 2083, the output shaft drives the lifting worm 2082 to rotate, and the lifting worm 2082 and the lifting worm wheel 2084 are meshed with each other. Since the lifting worm wheel 2084 is fixed on one side of the T-shaped rod, under the action of the meshing transmission, the T-shaped rod will rotate along the limit seat 209, so that the pulleys 2086 symmetrically arranged on both sides of the end of the vertical surface of the T-shaped rod slide in the inclined groove 206 at the front end of the inclined bottom plate 403205, so that the head pad 201 is lifted as the T-shaped rod moves. By controlling the forward and reverse rotation and rotation speed of the lifting motor 2083, the lifting angle and speed of the head pad 201 can be accurately adjusted to meet the different body position requirements of the parturient;

[0035] The working principle of the tilting assembly 207 is as follows: by starting the tilting motor 2074, the tilting worm 2071 at the front end rotates accordingly, and the tilting worm 2071 meshes with the tilting worm wheel 2075. When the tilting worm 2071 rotates, the tilting worm wheel 2075 rotates. The power rod 2076 set at the front end of the tilting worm wheel 2075 is connected to the tilting ring 204. The fixed blocks 2073 at both ends of the power rod 2076 are fixedly connected to the bottom of the head pad 201. Therefore, the rotation of the tilting worm wheel 2075 will drive the tilting ring 204 to rotate through the power rod 2076, thereby tilting the head pad 201 to the left or right as a whole. By controlling the forward and reverse rotation and rotation parameters of the tilting motor 2074, the precise control of the tilting angle and direction of the head pad 201 can be achieved to meet different operation requirements during surgery and prevent supine hypotension syndrome.

[0036] In this embodiment, the lifting component 208 can accurately adjust the head height according to the specific needs of the parturient, such as different physical conditions, surgical progress, etc. When the parturient is slightly dizzy, the head can be appropriately raised slightly to improve the blood supply to the brain; when it is necessary to better expose the surgical field, it can be accurately adjusted to a suitable height, which not only ensures the comfort of the parturient, but also facilitates the smooth progress of the operation;

[0037] When the tilting component 207 tilts to the left, it can effectively prevent supine hypotension syndrome, reduce the pressure on the inferior vena cava by changing the position of the uterus, ensure the stability of the maternal blood circulation, and then ensure the blood supply to the fetus, reducing the risk of fetal distress, etc.; when tilting to the right, it can provide the surgeon with a clearer surgical field of view according to the surgical site and operation requirements, making it convenient for the doctor to perform delicate operations in cesarean section, such as suturing the uterine incision, exploring the abdominal cavity, etc., thereby improving the efficiency and quality of the operation.

[0038] Example 2

[0039] As attached Figure 1 , 2As shown, the waist assembly 1 includes a hydraulic motor 101, a lifting connecting rod 102, a lifting connector 103, a lifting slide 104, a telescopic column 105, a lifting pulley 2086106, and a waist plate 107; the lifting slides 104 are symmetrically arranged at the front ends of both sides of the bottom of the box body 404, and the lifting connectors 103 are symmetrically arranged at the rear end to rotate and connect the connecting rods; the lifting slides 104 are symmetrically arranged at both sides of the front end of the waist plate 107, and the lifting connectors 103 are symmetrically arranged at both sides of the rear end; the connecting rods 303 are The front end is rotatably connected to the lifting connector 103 on the box body 404, and the rear end is rotatably connected to the lifting pulley 2086106 at the bottom of the waist plate 107. The other front end is rotatably connected to the lifting connector 103 at the bottom of the waist plate 107, and the rear end is rotatably connected to the lifting pulley 2086106 at the bottom of the box body 404. A circular hole is set at the intersection of the connecting rods on both sides to connect the telescopic column 105; a hydraulic motor 101 is horizontally set in the middle of the telescopic column 105; the hydraulic motor 101 is fixedly connected to the rear end of the box body 404;

[0040] In this embodiment, the working principle of the waist component 1 is as follows: by starting the hydraulic motor 101, its telescopic action will push or pull the telescopic column 105, and the telescopic column 105 is located in the circular hole at the intersection of the connecting rods on both sides. When the telescopic column 105 is extended and retracted, it will drive the connecting rod to move. Under the action of the telescopic column 105, the two connecting rods will produce relative movement, thereby realizing the lifting and lowering of the waist board 107. The precise control of the hydraulic motor 101 can make the lifting height and speed of the waist board 107 accurately adjusted, so as to accurately adjust the position of the uterus and reduce the pressure on the inferior vena cava. At the same time, the waist component 1 can better fit the body shape of the parturient and provide stable and comfortable support.

[0041] In this embodiment, the waist component 1 can accurately adjust the waist height according to individual differences of the mother, such as uterine size, body shape, etc., so that the uterus can achieve the best leftward displacement effect under the action of gravity, thereby minimizing the pressure on the inferior vena cava, effectively preventing the occurrence of supine hypotension syndrome, ensuring the stability of maternal blood pressure, providing strong protection for surgical safety, and also being beneficial to the health of the fetus.

Through the connection of the connecting rod, the rotation of the opening and closing motor 301 is converted into the opening and closing and lifting and lowering actions of the leg support block 306. When the opening and closing motor 301 rotates forward or reversely, the opening or closing degree of the leg support block 306 can be controlled. At the same time, under the synergistic effect of the connecting rod structure, the leg support block 306 will also achieve a certain degree of lifting and lowering during the opening and closing process, thereby achieving the functions of promoting venous return of the lower limbs and facilitating surgical operations.

At the same time, it can also make the doctor more handy during the operation, and improve the convenience and safety of the operation.

[0046] In summary, the present invention drives the lifting worm 2082 to rotate through the lifting motor 2083, which meshes with the lifting worm wheel 2084, so that the T-shaped rod moves in the vertical direction under the restriction of the limit seat 209, thereby realizing the lifting of the head pad 201, which helps to improve the breathing of the parturient, reduce the pressure on the neck, and relieve the discomfort symptoms caused by the supine position, such as dizziness, nausea, etc., and at the same time can also promote the venous return of the upper body to a certain extent; and, the tilting motor 2074 drives the tilting worm 2071 to rotate, meshes with the tilting worm wheel 2075, and rotates the power rod 2076, and the fixed blocks 2073 at both ends of the power rod 2076 drive the tilting ring 204 at the bottom of the head pad 201 to rotate, thereby realizing the left and right tilting of the head pad 201; it can prevent supine hypotension syndrome and reduce the compression of the uterus on the inferior vena cava;

[0047] At the same time, the hydraulic motor 101 drives the telescopic column 105 to extend and retract, and the connecting rod structure drives the waist board 107 to rise and fall, so that the waist height can be accurately adjusted, so that the uterus can be better shifted to the left under the action of gravity, and the pressure on the inferior vena cava can be reduced, and the supine hypotension syndrome can be effectively prevented. In addition, the lifting of the waist board 107 can better fit the body shape of the parturient, provide comfortable and stable waist support, reduce waist pressure, and avoid the parturient from moving the body due to waist discomfort during the operation, thereby ensuring the stability of the surgical position and facilitating the smooth progress of the operation.
