Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasonic examination, and particularly relates to an auxiliary device for pelvic floor ultrasonic examination. Background Art

[0002] Pelvic floor ultrasonic examination usually adopts transabdominal ultrasonic examination or transperineal ultrasonic examination. The examination bed usually consists of a head bed board, a leg bed board rotatably connected to one side of the head bed board, and leg supports located on both sides of the leg bed board. During transabdominal ultrasonic examination, the top of the head bed board and the leg bed board are flush, and the patient lies flat on the examination bed to receive ultrasonic examination. During transperineal ultrasonic examination, the upper body of the patient lies flat on the head bed board, and the two legs are respectively supported on the leg supports. However, the existing leg support plates are often fixedly arranged and cannot be adjusted according to different patients, resulting in some patients receiving examinations in uncomfortable postures, which is likely to cause fatigue and may also affect the ultrasonic examination results. In addition, to avoid hindering the doctor's operation, the leg bed board needs to be rotated downward, and the downward rotation of the leg bed board requires a certain space, resulting in a relatively high examination bed, which is not convenient for some patients to get on and off the bed.

The hypotenuses of the two trapezoidal blocks are respectively slidably matched with the two guide inclined surfaces.

[0010] Preferably, a gear is coaxially fixed at the rotational connection between the second rotating plate and the sliding plate. A moving frame is slidably arranged inside the lifting frame. A lead screw rotatably penetrating through the moving frame is rotatably arranged inside the lifting frame. A rack is fixedly installed on one side of the moving frame. The gear is meshed with the rack.

[0011] Preferably, inclined chutes are provided at the bottoms of the two first rotating frames. Two push rods slidably penetrate through one side of the lifting frame. Fixing rods are fixedly installed at one ends of the two push rods. The two fixing rods are respectively slidably matched inside the two chutes.

[0012] Preferably, a guide rod is fixedly installed on the lifting frame. Two sliding seats are symmetrically and slidably connected to the lifting frame.

[0014] Preferably, a double-headed screw is rotatably arranged on the base. The two sliding frames are respectively screwed to both ends of the double-headed screw.

[0015] Preferably, a second electric push rod is fixedly installed inside the lifting frame. A fifth connecting rod is rotatably connected between the telescopic end of the second electric push rod and the bottom of the back plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention is provided with a second rotating frame, a sliding sleeve and a fourth connecting rod. When a patient undergoes a transperineal pelvic floor ultrasound examination, the first electric push rod pushes the sliding sleeve to slide on one side of the second rotating frame so that the two fourth connecting rods push the foot board to rise, and at the same time the leg board rotates upward so that the leg board and the foot board lift the patient's legs upward and bend them. Then the two second rotating frames rotate to both sides so that the leg board and the foot board drive the patient's legs to open to both sides. By controlling the moving distance of the sliding sleeve and the rotation angle of the second rotating frame, any patient can be examined in a relatively comfortable manner to avoid fatigue and affect the examination results.

[0018] (2) The present invention is provided with a top plate, which supports the legs during transabdominal ultrasound examination, so that the patient can lie flat to receive ultrasound examination. During transperineal ultrasound examination, the second rotating plate is rotated to drive the top plate and the first rotating plate to rotate, so that the height of the top plate is lowered, and then the sliding plate is used to drive the top plate to move to the bottom of the seat cushion and the back plate to avoid obstructing the doctor's operation. The existence of the top plate reduces the width setting of the leg plate and the foot plate, so that after the second rotating frame is rotated, there is a larger area between the two leg plates for the doctor to perform pelvic floor ultrasound examination.

[0019] (3) The present invention is provided with a clamping rod, a clamping groove, a trapezoidal block and a second spring. Initially, the second spring pushes the trapezoidal block to contact with the guiding inclined surface at the end of the fixed plate. When the movable frame drives the rack to move, the trapezoidal block and the guiding inclined surface first hinder the movement of the slide plate, so that the rack drives the gear to rotate through meshing transmission, thereby causing the second rotating plate to rotate and drive the height of the top plate to drop until the top plate contacts the slide plate, so that the second rotating plate and the gear cannot continue to rotate. At this time, continuing to drive the rack to move will cause the rack to drive the gear to move synchronously, thereby driving the second rotating plate and the slide plate to move toward the bottom of the seat cushion and the back plate. At the same time, the fixed plate will push the trapezoidal block to compress the first spring and push the clamping rod. The rod extends into the slot on the second rotating plate, so that when the trapezoidal block moves between the two fixed plates, the second rotating plate and the top plate are always fixed relatively to the sliding plate, so that when the moving frame moves in the opposite direction, the top plate is prevented from moving up and colliding with the bottom of the back plate and the seat cushion to hinder the sliding plate and the top plate from being pushed out, until the vertical end of the sliding plate of the L-shaped structure collides with one side of the lifting frame so that the sliding plate cannot continue to move, and at this time the two trapezoidal blocks move out from between the two fixed plates, the second spring causes the trapezoidal block to drive the clamping rod out of the slot, and then the moving frame continues to drive the rack to move so that the gear drives the second rotating plate to rotate, so that the top plate is raised and reset again, thereby ensuring the smooth expansion and contraction of the sliding plate and the top plate.

[0020] (4) The present invention is provided with a push plate, a sixth connecting rod, a sliding seat, a third connecting rod, a push rod, a fixed rod and a sliding groove. After the moving frame drives the sliding plate and the top plate to move and contract, the moving frame can continue to move to push the push plate to move along the guide rod and compress the first spring. The two sixth connecting rods push the sliding seat to move to both sides, so that the two third connecting rods push the push rod to drive the fixed rod to move. The fixed rod pushes the second rotating frame to rotate outward through the sliding groove. When the moving frame moves in the reverse direction, the elastic force of the first spring pushes the push plate to move in the reverse direction, thereby realizing the adjustment of the rotation angle of the second rotating frame, reducing the setting of driving equipment and lowering the equipment cost.

[0021] (5) The present invention is provided with a lifting assembly. The top plate shrinks in a sliding manner, so that the height of the equipment is not restricted. Therefore, when the double-headed screw is rotated to make the two sliding frames move relatively, one ends of the two groups of second connecting rods are driven to move respectively, and then the two groups of first connecting rods rotate on the base respectively, so that the tops of the two groups of second connecting rods drive the lifting frame to lift, thereby realizing the lifting of the equipment, enabling it to move to a height suitable for a doctor to manipulate the ultrasonic probe for examination, making the doctor's operation more stable and avoiding harm to the patient. At the same time, it is also convenient for different patients to get on and off the bed.

[0022] (6) The present invention is provided with a second electric push rod and a fifth connecting rod. The telescoping of the second electric push rod enables the fifth connecting rod to push the back plate to rotate, which can assist the patient to lie flat or get up, improving the efficiency and comfort for patients with inconvenient movement or relatively stiff bodies.

Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-9 As shown, the present invention provides the following technical solutions:

[0035] An auxiliary device for pelvic floor ultrasound examination, including a base 1 and a lifting frame 2 arranged above the base 1. There is a lifting component between the base 1 and the lifting frame 2. A seat cushion 4 is fixedly installed at the top of the lifting frame 2. A back panel 3 is rotatably connected to the top of the lifting frame 2. Two second rotating frames 13 are symmetrically and rotatably connected to one side of the lifting frame 2. The tops of the two second rotating frames 13 are both rotatably connected to leg plates 5. The ends of the two leg plates 5 are both rotatably connected to foot plates 6;

[0036] The bottoms of the two second rotating frames 13 are both fixedly installed with first electric push rods 21. The telescopic ends of the two first electric push rods 21 are both fixedly connected with sliding sleeves 22. Two fourth connecting rods 23 are respectively rotatably connected between the two sliding sleeves 22 and the two foot plates 6.

[0037] Based on the above - disclosed structure, during pelvic floor ultrasound examination:

[0038] Initially, the tops of the back panel 3, the leg plates 5 and the foot plates 6 are all flush with the top of the seat cushion 4. When performing trans - abdominal ultrasound examination, the patient sits on the seat cushion 4 and then lies flat. The plane formed by the back panel 3, the leg plates 5 and the foot plates 6 is above. Then the doctor uses an ultrasound probe to perform ultrasound examination on the patient's abdomen;

[0039] When performing transperineal ultrasound examination, the patient sits on the cushion 4 and then lies flat on the back plate 3. The two legs are respectively placed on the two sets of leg plates 5 and foot plates 6 on both sides. Then, the two first electric push rods 21 are respectively activated to push out the telescopic ends, thereby driving the two sliding sleeves 22 to move respectively. A parallelogram is formed among the sliding sleeve 22, the foot plate 6 and the two fourth connecting rods 23, so that the sliding sleeve 22 is always parallel to the foot plate 6. When the sliding sleeve 22 moves, the two fourth connecting rods 23 push the top of the foot plate 6 to move, and at the same time, the leg plate 5 rotates upward around the rotation connection with the second rotating frame 13, so that the leg plate 5 and the foot plate 6 lift and bend the patient's legs upward. Then, the two second rotating frames 13 are respectively rotated to both sides, so that the leg plate 5 and the foot plate 6 drive the patient's legs to open to both sides. Then, the doctor uses an ultrasound probe to perform an ultrasound examination from the patient's perineum. Thus, by controlling the moving distance of the sliding sleeve 22 and the rotation angle of the second rotating frame 13, any patient can be examined in a more comfortable manner, avoiding fatigue and affecting the examination results.

[0040] In addition, two first rotating frames 12 are symmetrically and rotatably connected to one side of the base 1. A plurality of universal wheels 20 are fixed to the base 1 and the bottoms of the two first rotating frames 12. Telescopic cylinders 11 are fixedly installed on both of the two first rotating frames 12. Telescopic rods 10 are fixedly installed on both of the two second rotating frames 13. The bottom ends of the two telescopic rods 10 respectively slide into the two telescopic cylinders 11. Based on this, the device can be easily moved by rolling the plurality of universal wheels 20 fixed to the base 1 and the bottoms of the two first rotating frames 12 on the ground. When the second rotating frame 13 rotates outward, the telescopic rod 10 pushes the telescopic cylinder 11 to drive the first rotating frame 12 to rotate outward, so that the first rotating frame 12 is always located below the second rotating frame 13. Furthermore, the second rotating frame 13 is assisted in supporting through the friction between the telescopic rod 10 and the telescopic cylinder 11, avoiding the second rotating frame 13 from bending and breaking and improving the service life.

[0041] In addition, to provide a larger operation area for the doctor during transperineal ultrasound examination, two fixing plates 28 are fixedly installed inside the lifting frame 2. A slide plate 9 with an L-shaped structure is slidably connected between the two fixing plates 28. One end of the slide plate 9 slides through one side of the lifting frame 2. A first rotating plate 8 and a second rotating plate 27 are rotatably connected to the slide plate 9. A top plate 7 is rotatably connected between the ends of the first rotating plate 8 and the second rotating plate 27, and the top plate 7 is located between the two leg plates 5. Based on this, initially, the top of the top plate 7 is flush with the top of the seat cushion 4. During transabdominal ultrasound examination, the top plate 7 can support the legs, and the patient lies flat for ultrasound examination. During transperineal ultrasound examination, first rotate the first rotating plate 8 and the second rotating plate 27 to lower the height of the top plate 7, and then slide the slide plate 9 through the lifting frame 2 to move the top plate 7 and the slide plate 9 below the seat cushion 4 and the back plate 3 to avoid obstructing the doctor's operation. In addition, the presence of the top plate 7 reduces the width of the leg plates 5 and the foot plates 6, so that after the second rotating frame 13 moves outward, there is a larger area between the two leg plates 5 for the doctor to perform pelvic floor ultrasound examination operations.

[0042] Regarding the movement of the top plate 7 as described above, the following structure is preferably provided:

[0043] Guide inclined surfaces 29 are provided at the ends of both fixing plates 28. Card slots 41 are provided on both sides of the second rotating plate 27. Two clamping rods 42 that are symmetrically arranged inside the slide plate 9 and slidably cooperate with the two card slots 41 respectively are provided. Trapezoidal blocks 40 are fixedly installed at one ends of the two clamping rods 42. Second springs 43 are fixedly connected between the two trapezoidal blocks 40 and the slide plate 9. The hypotenuses of the two trapezoidal blocks 40 are slidably engaged with the two guide inclined surfaces 29 respectively;

[0044] A gear 26 is coaxially fixed at the rotational connection between the second rotating plate 27 and the slide plate 9. A moving frame 31 is slidably arranged inside the lifting frame 2. A lead screw 37 that is rotatably provided inside the lifting frame 2 and threadedly penetrates the moving frame 31 is provided. A rack 30 is fixedly installed on one side of the moving frame 31. The gear 26 is meshed with the rack 30.

[0045] As can be seen from the above, initially, the hypotenuse of the two trapezoidal blocks 40 abuts against the guiding inclined surfaces 29 at the ends of the two fixing plates 28. Rotating the driving lead screw 37 causes the moving frame 31 to move away from the leg plate 5, thereby driving the rack 30 to move. The two second springs 43 respectively push the two trapezoidal blocks 40, causing the trapezoidal blocks 40 and the guiding inclined surfaces to obstruct the movement of the sliding plate 9. Therefore, at this time, there is no relative movement between the sliding plate 9 and the fixing plate 28. The movement of the rack 30 causes the meshing-connected gear 26 to drive the second rotating plate 27 to rotate downward. The ends of the second rotating plate 27 and the first rotating plate 8 drive the bottom of the top plate 7 to descend until the top plate 7 abuts against the sliding plate 9, making the second rotating plate 27 unable to continue rotating downward, thereby making the gear 26 unable to continue rotating. And at this time, the card slots 41 on both sides of the second rotating plate 27 are respectively located on one side of the two clamping rods 42. Then continue to drive the lead screw 37 to drive the moving frame 31 to move away from the leg plate 5. Since the gear 26 cannot rotate, the meshing between the rack 30 and the tooth part of the gear 26 causes the rack 30 to drive the gear 26 to move synchronously, thereby causing the second rotating plate 27 to drive the sliding plate 9 and the top plate 7 to move downward below the seat cushion 4 and the backrest 3. At the same time, the guiding inclined surface 29 at the end of the fixing plate 28 pushes the trapezoidal block 40 to gradually contract into the sliding plate 9. The trapezoidal block 40 pushes the clamping rod 42 to extend into the card slot 41 on the second rotating plate 27 and compress the second spring 43, so that when the two trapezoidal blocks 40 are located between the two fixing plates 28, the sliding plate 9, the second rotating plate 27 and the top plate 7 are relatively fixed;

[0046] Therefore, when the driving lead screw 37 rotates to make the moving frame 31 move towards the leg plate 5, the second rotating plate 27 cannot rotate upward in the sliding plate 9, so that the moving frame 31 and the rack 30 first push the gear 26 and the sliding plate 9 and the top plate 7 to extend out from the bottom of the seat cushion 4 and the backrest 3 until the vertical end of the L-shaped sliding plate 9 abuts against one side of the lifting frame 2 and the sliding plate 9 cannot move any further. And at this time, both trapezoidal blocks 40 have moved out between the two fixing plates 28. The elastic force of the two second springs 43 causes the trapezoidal blocks 40 to drive the clamping rods 42 to disengage from the card slots 41. Then continue to drive the lead screw 37 to rotate to make the moving frame 31 move towards the leg plate 5, which can make the rack 30 and the gear 26 meshingly drive, so that the gear 26 drives the second rotating plate 27 to rotate upward, thereby driving the top plate 7 to rise and reset again.

[0047] In addition, regarding the rotation of the first rotating frame 13, preferably, the following structure is provided:

[0048] Both bottoms of the two first rotating frames 13 are provided with inclined chutes 38. One side of the lifting frame 2 is slidably penetrated by two push rods 18. One end of each of the two push rods 18 is fixedly installed with a fixing rod 39. The two fixing rods 39 are respectively slidably fitted in the two chutes 38;

[0049] A guide rod 33 is fixedly installed on the lifting frame 2. Two sliding seats 36 are symmetrically and slidably connected to the lifting frame 2. Third connecting rods 19 are respectively rotatably connected between the two sliding seats 36 and the two push rods 18. A push plate 32 is slidably connected to the guide rod 33, and the push plate 32 is located on one side of the moving frame 31. A first spring 34 is fixedly connected between the push plate 32 and the lifting frame 2. Sixth connecting rods 35 are respectively rotatably connected between the two ends of the push plate 32 and the two sliding seats 36.

[0050] As can be seen from the above, after the moving frame 13 drives the sliding plate 9 and the top plate 7 to move and contract, when the screw rod 37 is continuously driven to rotate so that the moving frame 31 moves away from the leg plate 5, the moving frame 31 pushes the push plate 32 to move along the guide rod 33. At the same time, the push plate 32 compresses the first spring 34. The two sixth connecting rods 35 at both ends of the push plate 32 respectively push the two sliding seats 36 to move to both sides on the lifting frame 2, so that the two third connecting rods 19 respectively push the two push rods 18 to move, and further drive the two fixed rods 39 to move, so that the two fixed rods 39 respectively push the two second rotating frames 13 to rotate outward through the two sliding grooves 38; conversely, when the screw rod 37 is driven to rotate so that the moving frame 31 moves towards the leg plate 5, the elastic force of the first spring 34 pushes the push plate 32 to move along the guide rod 33, so that the two sixth connecting rods 35 at both ends of the push plate 32 respectively pull the two sliding seats 36 to move towards the middle on the lifting frame 2, so that the two third connecting rods 19 respectively pull the two push rods 18 to move, and further pull the two fixed rods 39 to move, so that the two fixed rods 39 respectively pull the second rotating frames 13 to rotate inward through the two sliding grooves 38, so as to realize the adjustment of the rotation angle of the second rotating frame 13.

[0051] In addition, regarding the lifting assembly, the following structure is preferably provided:

[0052] The lifting assembly includes two sliding frames 17 symmetrically and slidably connected in the base 1. Second connecting rods 15 are rotatably connected to both sides of the two sliding frames 17. The tops of the four second connecting rods 15 are respectively rotatably connected to the lifting frame 2. First connecting rods 14 are respectively rotatably connected between the middle parts of the four second connecting rods 15 and the base 1;

[0053] A double-headed screw rod 16 is rotatably provided on the base 1. The two sliding frames 17 are respectively screwed to both ends of the double-headed screw rod 16.

[0054] As can be seen from the above, driving the double-headed screw 16 to rotate causes the two sliding brackets 17 to move along the double-headed screw 16 towards both ends. The two sliding brackets 17 respectively drive the bottom ends of the two groups of second connecting rods 15 to move. The middle parts of the two groups of second connecting rods 15 respectively push the two groups of first connecting rods 14 to rotate on the base 1. At the same time, the top ends of the two groups of second connecting rods 15 push the lifting frame 2 to move upward; conversely, driving the double-headed screw 16 to rotate causes the sliding brackets 17 on both sides to move along the double-headed screw 16 towards the middle, causing the lifting frame 2 to move upward, thereby realizing the lifting of the examination bed, enabling it to move to a height suitable for the doctor to operate the ultrasonic probe for examination, making the doctor's operation more stable and avoiding harm to the patient. At the same time, it is used to assist patients of different heights to get on and off the bed.

[0055] In addition, a second electric push rod 24 is fixedly installed inside the lifting frame 2. A fifth connecting rod 25 is rotatably connected between the telescopic end of the second electric push rod 24 and the bottom of the back plate 3. Based on this, for patients with limited mobility or relatively stiff bodies, first start the second electric push rod 24 to extend its telescopic end so that the fifth connecting rod 25 pushes the back plate 3 to rotate upward, causing the back plate 3 to rotate and rise. After the patient sits on the cushion 4 and leans against the back plate 3, start the second electric push rod 24 to gradually retract its telescopic end so that the fifth connecting rod 25 pulls the back plate 3 to rotate downward, thereby helping the patient to gradually lie flat. Conversely, it can help the patient to get up, improving efficiency and the patient's comfort.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
