Description
Technical Field
[0001] The utility model relates to the technical field of medical treatment, in particular to a position limiting protection device after hip joint surgery. Background Art
[0002] Total hip replacement surgery can significantly reduce hip pain and improve joint function. However, patients face various complications after surgery, with postoperative dislocation being a common and serious complication. After hip replacement surgery, the patient's affected limb needs to be abducted to a neutral position to prevent early hip dislocation and facilitate postoperative care. Currently, to maintain a neutral position after hip replacement surgery, a pillow is used to separate the legs to prevent postoperative joint dislocation, and one leg is elevated with a pillow. However, the size of the pillow is fixed, making it inconvenient to adjust the angle between the legs. Furthermore, when using a pillow to elevate the legs, the elevation angle cannot be adjusted, and the patient's feet have no other support limiters, which can easily cause the foot to rotate or evert, resulting in complications such as foot drop. Therefore, it is necessary to provide a device that can adjust the distance and angle between the legs so that the patient's legs can be kept in a neutral position and the angle of the leg elevation can be adjusted to support the patient's feet and reduce the occurrence of foot complications.

[0026] A specific embodiment, as shown in the figure, is a better embodiment of the present invention. A postoperative limiting protection device for hip joint joint mainly comprises a base plate 1, the base plate 1 is placed on the bed plate, two limiting structures are installed on the base plate 1, and the patient's legs are fixed in a limiting structure respectively, the limiting structure mainly comprises a fixing plate 4 and a limiting plate 2, the lower end face of the fixing plate 4 is installed on the upper end face of the base plate 1, the upper end face of the fixing plate 4 is installed with the limiting plate 2, one end of the limiting plate 2 in the length direction is rotatably connected to one end of the fixing plate 4 in the length direction, and the lower end face of the limiting plate 2 is movably fitted with the upper end face of the fixing plate 4; the other end of the limiting plate 2 in the length direction is provided with a long strip plate hole 10, the length direction of the plate hole 10 is parallel to the length direction of the limiting plate 2, and the other end of the fixing plate 4 ... and the length direction of the plate hole 10 is parallel to the length direction of the limiting plate 2. Both sides of the plate are provided with connecting parts 5, each of which is provided with a rod hole 6, and a rotating shaft is installed in each of the rod holes 6. The axis of the rotating shaft is perpendicular to the length direction of the fixing plate 4. A support rod 7 is rotatably connected to the rotating shaft, and one end of the support rod 7 is rotatably connected to the rod hole 6. The other end of the support rod 7 passes through the plate hole 10 of the limit plate 2. Each of the support rods 7 is threadedly connected to two limiting nuts, and the two limiting nuts are respectively located on both sides of the limiting plate 2. The outer diameter of the limiting nut is larger than the width of the plate hole 10, and the two limiting nuts are respectively an upper limiting nut 9 and a lower limiting nut 8; a plurality of fixing straps 3 are installed on the upper end surface of the limiting plate 2, and a plurality of fixing straps 3 are arranged along the length direction of the limiting plate 2.
[0027] The patient's legs are fixed to the base plate 1 by a limiting structure. The patient's unoperated leg can move the base plate 1 by its own strength in conjunction with the strength of the waist. In order to prevent the base plate 1 from being moved along with the patient when moving on the bed, resulting in the legs fixed in the limiting structure of the base plate being passively moved, which can easily cause hip dislocation of the operated leg. Therefore, further, multiple belts are provided on the base plate 1, and the multiple belts are arranged along the length direction of the base plate 1. The patient is fixed to the base plate 1 by the belts. There are multiple belts, and the belts can be selected at appropriate positions according to the patient's waist position for fixing, so that the patient can be well fixed to the base plate. Furthermore, the length of the base plate 1 ranges from 1.2 to 1.8 meters. According to actual conditions, the length of the base plate 1 can be set to 1.2 meters, 1.5 meters, 1.8 meters, etc., so that the patient's lower body and part of the upper body or the entire upper body are all located on the base plate 1. Because the patient's own center of gravity is pressed on the base plate 1, the patient's waist and legs are fixed on the base plate 1. If the patient relies solely on his or her own strength, it is difficult for the patient to move on the base plate, so the patient's legs are well limited and the patient's hip joint is not easily dislocated.
[0028] After hip replacement surgery, it is sometimes necessary to raise the leg on the operated side to a certain angle to reduce the occurrence of foot complications. However, the raised leg on the operated side cannot be moved at will and also needs to be fixed. Select a limiting structure at the corresponding position according to the leg on the operated side to raise the leg. In the utility model, the fixing plate 4 is fixed on the base plate 1, and the fixing plate 4 is rotatably connected to the limiting plate 2. The fixing plate 4 and the limiting plate 2 can be connected by a rotating shaft or by a hinge structure. These structures are common existing structures and will not be described in detail here. When the patient's leg needs to be raised, the upper limit nut 9 on the support rod 7 is loosened, and the limit plate 2 is rotated so that the angle between the limit plate 2 and the fixed plate 4 becomes larger. The limit plate 2 is raised, and the support rod 7 on the fixed plate 4 is rotated so that the support rod 7 is always located in the plate hole 10 of the limit plate 2. Then the upper limit nut 9 and the lower limit nut 8 on the support rod 7 are rotated so that the lower end surface of the upper limit nut 9 abuts against the upper end surface of the limit plate 2, and the upper end surface of the lower limit nut 8 abuts against the lower end surface of the limit plate 2. The limit plate 2 is clamped and fixed by the upper limit nut 9 and the lower limit nut 8 of the support rod 7. The patient's leg on the surgical side is placed on the limit plate 2, and the foot is raised to reduce the occurrence of foot complications. In order to prevent the leg on the surgical side from sliding off the limit plate 2, multiple fixing straps 3 on the limit plate 2 are used to fix the patient's leg on the surgical side to the limit plate 2.
[0029] When the leg on the operated side is raised and the leg that was not operated on is laid flat, or when both legs are laid flat, both legs of the patient need to be kept in neutral abduction to avoid hip dislocation. Therefore, two limiting structures are set on the base plate 1, and the patient's legs are fixed by the two limiting structures so that the angle between the legs cannot be changed arbitrarily and the neutral abduction position is maintained. Because the patient's legs are fixed on the limiting plate 2 and the fixing plate 4 is installed on the base plate 1, but the limiting plate 2 can rotate around the fixing plate 4, it is necessary to fix the limiting plate 2 and the fixing plate 4; the upper limit nut 9 and the lower limit nut 8 can be completely removed so that the limiting plate 2 and the fixing plate 4 fit together, and the support rod 7 always passes through the plate hole 10 on the limiting plate 2, and then the upper limit nut 9 and the lower limit nut 8 are threadedly connected to the support rod 7 and abut against the upper end surface of the limiting plate 2, and the limiting plate 2 is clamped on the fixing plate 4. The limiting plate 2 and the fixing plate 4 act as a whole, and the patient's legs can be well fixed on them. The lower limit nut 8 can also be rotated downward, the lower end face of the lower limit nut 8 abuts against the fixed plate 4, the limit plate 2 is pressed on the lower limit nut 8, and the lower end face of the upper limit nut 9 abuts against the upper end face of the limit plate 2, so that the limit plate 2 is placed as flat as possible and fixed together with the fixed plate 4.
[0030] Because different patients have different body shapes, the distance and angle between the legs will vary when the legs are kept in the neutral abduction position. Therefore, further, two elongated sliding holes are opened on the bottom plate 1, and the length directions of the two sliding holes are parallel to the width direction of the bottom plate 1, and the two sliding holes are respectively a first sliding hole 11 and a second sliding hole 17, and each of the limiting structures is connected to the first sliding hole 11 and the second sliding hole 17; the side surface of the fixing plate 4 of each limiting structure is protruded with two fixing parts 12, and the two fixing parts 12 are located on the same side of the fixing plate 4, and each of the fixing parts 12 is respectively opened with an elongated third sliding hole 13 and an elongated fourth sliding hole 16, and the length directions of the third sliding hole 13 and the fourth sliding hole 16 are parallel to the length direction of the fixing plate 4, and the first sliding hole 11 and the third sliding hole 13, the second sliding hole 17 and the fourth sliding hole 16 are all penetrated by a fixing screw 14, the nail head of the fixing screw 14 abuts the lower end surface of the bottom plate 1, and the fixing screw 14 is threadedly connected with a fixing nut 15, and the lower end surface of the fixing nut 15 abuts the upper end surface of the fixing plate 4. The patient's legs are fixed in the limiting plate 2 by the fixing belt 3, and the limiting plate 2 is fixed to the fixing plate 4 by the limiting nut. After adjusting the spacing and angle between the two limiting structures so that the patient's legs are in the neutral position of abduction, use the fixing screw 14 to pass through the first sliding hole 11 on the base plate 1 and the third sliding hole 13 on the fixing plate 4 in sequence, and use the fixing nut 15 to connect with the fixing screw 14 so that the lower end surface of the fixing nut 15 abuts against the fixing plate 4, and the nail head of the fixing screw 14 abuts against the lower end surface of the base plate 1, clamping and fixing the fixing plate 4 on the base plate 1. Similarly, use the fixing screw 14 to pass through the second sliding hole 17 and the fourth sliding hole 16 in sequence, and use the fixing nut 15 to fix it. The two fixing screws 14 can make the fixing plate 4 well fixed on the base plate 1, and the positions of the two limiting structures are fixed.
[0031] Furthermore, the upper end surface of the limiting plate 2 is covered with a cushion, and the patient's legs can be placed on the limiting plate 2 for greater comfort.
[0032] Furthermore, the fixing strap 3 is fixed with Velcro, which is convenient for fixing, and the fixing length of the fixing strap 3 can be adjusted according to the thickness of the patient's legs. Alternatively, the length of the fixing strap 3 can be adjusted, and the fixing strap 3 is fixed with a buckle, which is a common existing structure and will not be described in detail here.
[0033] Furthermore, a quilted layer is provided on the side of the fixing belt 3 that contacts the human body. The quilted layer acts as a buffer to improve the comfort of use.
[0034] Furthermore, an anti-slip pad is provided on the lower end surface of the base plate 1 to prevent the base plate 1 from sliding.
[0035] Furthermore, an anti-slip pad is provided on the lower end surface of the fixing plate 4 to prevent the fixing plate 4 from sliding.
