Description

Technical Field

[0001] This utility model relates to the field of surgical nursing instruments, specifically a limb support device for day surgery. Background Technology

[0002] Day surgery refers to surgeries that allow patients to get out of bed and be discharged on the same day. These are mostly minor surgeries of the limbs. In lower limb surgeries, the patient's lower limbs need to be elevated so that the lower part of the limbs is in front of the medical staff, giving them a better surgical field of vision.

[0003] Existing surgical limb support devices mostly use two methods: nurse support and pole support. Nurse support involves the nurse lifting the patient's lower limbs up. This method is time-consuming and laborious, and it also affects the surgeon's field of vision. The pole support method allows the patient's lower limbs to rest on the pole.

[0004] Chinese utility model patent CN213490195U discloses a limb support device for day surgery. Although this limb support device uses the cooperation of an arc-shaped rack and a main gear to fix the patient's lower limbs with a placement plate and an abdominal binder, making it easier to raise the patient's lower limbs for the doctor to perform surgery, the fixed position of the placement plate and the abdominal binder does not allow for the fixation of the lower limbs of people of different heights.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a bed board, straps, and an arc-shaped positioning plate. The bed board has a rotating plate with a T-shaped groove extending along its length. Limiting holes are distributed along the length of the bottom of the T-shaped groove. A T-shaped slider is slidably fitted inside the T-shaped groove. A fixing component is provided inside the T-shaped slider. The fixing component includes a pressure post, a limiting post, and a connecting plate. The pressure post and the limiting post are vertically arranged. The T-shaped slider has openings for the limiting post. The downward-moving through hole, as the T-shaped slider slides along the T-shaped groove, can sequentially be coaxial with the limiting hole. The limiting post can be vertically inserted into or disengaged from the limiting hole. A rotating shaft is provided between the pressure post and the limiting post. The rotating shaft is hinged to the connecting plate, and the rotating shaft and the connecting plate form a lever structure. The rotating shaft is fixedly connected to the T-shaped slider. Sliding posts are provided on both the limiting post and the pressure post. The surface of the connecting plate has elongated holes along its length that mate with the sliding posts. A spring is sleeved on the pressure post, and the spring provides the elastic force for the pressure post to return to its original position.

[0009] Optionally, the T-shaped slider has an internal mounting groove, which is an I-shaped groove. A pressure plate is fixedly connected to the surface of the pressure column. The mounting groove can be divided into a first vertical groove, a second vertical groove, and a horizontal groove. A limiting groove is provided on the first vertical groove to restrict the upward movement of the pressure plate. The two ends of the spring are fixedly connected to the pressure plate and the limiting groove, respectively. A relief groove is provided on the horizontal groove to avoid the connecting plate from rotating and getting stuck.

[0013] This utility model provides a limb support device for day surgery, which has the following beneficial effects:

[0014] 1. This day surgery limb support device, when the position of the strap and the arc-shaped positioning plate needs to be changed, press the pressure column, which moves the pressure column downward, causing the sliding column on the surface of the pressure column to move downward. Through the cooperation of the elongated hole, it causes the connecting plate to rotate counterclockwise around the pivot, causing the sliding column on the surface of the limiting column to move upward, causing the limiting column to move upward and disengage from the limiting hole. Through the cooperation of the T-shaped slider and the T-shaped groove, it changes the position of the strap and the arc-shaped positioning plate, which can accommodate people of different heights for lower limb fixation. After the strap and the arc-shaped positioning plate have moved to the appropriate position, release the pressure column. Due to the elasticity of the spring, the limiting column is firmly fixed in the limiting hole, preventing the strap and the arc-shaped positioning plate from moving and affecting the operation of medical staff.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0021] Please see Figures 1 to 4 The present invention provides a technical solution including a bed board 2, a strap 4, and an arc-shaped positioning plate 5. Universal wheels 1 are fixedly connected to both sides of the bottom end of the bed board 2. A connecting shaft 10 is rotatably connected inside the bed board 2. A groove 20 is formed in the center of the top end of the bed board 2, with the bottom end of the groove 20 penetrating through the bed board 2. The connecting shaft 10 is rotatably connected to the groove 20. A rotating plate 3 is fixedly connected to the surface of the connecting shaft 10. A T-shaped groove 9 extends along the length of the rotating plate 3. Limiting holes 6 are distributed along the length of the bottom of the T-shaped groove 9. A T-shaped slider 8 is slidably fitted inside the T-shaped groove 9. Lubricant is provided on the contact surface between the T-shaped groove 9 and the T-shaped slider 8 to ensure that the T-shaped slider 8 slides smoothly on the surface of the T-shaped groove 9. A fixing component 18 is provided inside the T-shaped slider 8. The fixing component 18 includes a pressure post 7, a limiting post 21, and a connecting plate 17. The pressure post 7 and the limiting post 21 are vertically arranged. The T-shaped slider 8 has a through hole for the limiting post 21 to move downward. The diameter of the through hole is larger than the diameter of the limiting hole 6, which facilitates the alignment of the limiting post 21 with the limiting hole 6. When the T-shaped slider 8 slides along the T-shaped groove 9, the through hole can be coaxial with the limiting hole 6 in sequence, and the limiting post 21 can be inserted into or removed from the limiting hole vertically. A rotating shaft 15 is provided between the pressure post 7 and the limiting post 21. The rotating shaft 15 is hinged to the connecting plate 17, and the rotating shaft 15 and the connecting plate 17 form a lever structure. The rotating shaft 15 is fixedly connected to the T-shaped slider 8. Both the limiting post 21 and the pressure post 7 are provided with sliding posts 11. The surface of the sliding posts 11 is coated with lubricating oil to avoid excessive wear on the long hole 19 opened in the connecting plate 17. The surface of the connecting plate 17 is provided with long holes 19 along its length to cooperate with the sliding posts 11. A spring 13 is sleeved on the pressure post 7, and the spring 13 provides the elastic force for the pressure post 7 to return to its original position.

[0022] Specifically, when it is necessary to change the position of the strap 4 and the arc-shaped positioning plate 5, press the pressure post 7 to move it downwards, which in turn moves the sliding post 11 on the surface of the pressure post 7 downwards. Through the cooperation of the elongated hole 19, the connecting plate 17 rotates counterclockwise around the rotating shaft 15, which in turn moves the sliding post 11 on the surface of the limiting post 21 upwards, which in turn moves the limiting post 21 upwards, causing the limiting post 21 to disengage from the limiting hole 6. Through the cooperation of the T-shaped slider 8 and the T-shaped groove 9, the position of the strap 4 and the arc-shaped positioning plate 5 is changed, which can accommodate people of different heights for lower limb fixation. After the strap 4 and the arc-shaped positioning plate 5 have moved to the appropriate position, release the pressure post 7. Due to the elasticity of the spring 13, the limiting post 21 is firmly fixed in the limiting hole 6, preventing the strap 4 and the arc-shaped positioning plate 5 from moving and affecting the operation of medical staff.

[0023] Please see Figures 1 to 4 The T-shaped slider 8 has an internal mounting groove 14, which is an I-shaped groove. The surface of the pressure column 7 is fixedly connected to the pressure plate 12. The mounting groove 14 can be divided into a first vertical groove 23, a second vertical groove, and a horizontal groove. The first vertical groove 23 has a limiting groove 22 that restricts the pressure plate 12 from moving upward. The two ends of the spring 13 are fixedly connected to the pressure plate 12 and the limiting groove 14, respectively. The horizontal groove is provided with a relief groove to avoid the connecting plate 17 from rotating, so as to prevent the connecting plate 17 from getting stuck when rotating.

[0024] Specifically, when the pressure column 7 is pressed down, it causes the pressure plate 12 to compress the spring 13. When the pressure column 7 is released, the spring 13 returns the pressure column 7 to its original position due to its elasticity.

[0025] During use, when it is necessary to change the position of the strap 4 and the arc-shaped positioning plate 5, press the pressure post 7 to move it downwards, which in turn moves the sliding post 11 on the surface of the pressure post 7 downwards. Through the cooperation of the elongated hole 19, this causes the connecting plate 17 to rotate counterclockwise around the rotating shaft 15, which in turn moves the sliding post 11 on the surface of the limiting post 21 upwards, causing the limiting post 21 to move upwards and disengage from the limiting hole 6. Through the cooperation of the T-shaped slider 8 and the T-shaped groove 9, this allows the limiting post 21 to move upwards and disengage from the limiting hole 6. By changing the position of the strap 4 and the arc-shaped positioning plate 5, the lower limbs can be fixed to people of different heights. After the strap 4 and the arc-shaped positioning plate 5 are moved to the appropriate position, the pressure column 7 is released. Due to the elasticity of the spring 13, the limiting column 21 is firmly fixed in the limiting hole 6, preventing the strap 4 and the arc-shaped positioning plate 5 from moving and affecting the operation of medical staff. When the pressure column 7 is pressed down, it causes the pressure plate 12 to compress the spring 13. When the pressure column 7 is released, the spring 13 returns the pressure column 7 to its original position due to the elasticity of the spring 13.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
