Description

Technical Field

[0001] This utility model relates to the field of joint replacement nursing technology, and in particular to an anti-dislocation nursing device for total hip replacement. Background Technology

[0002] Total hip replacement surgery is a procedure that replaces the femur and acetabulum with an artificial joint to treat severe hip joint diseases or injuries. The surgery is usually performed under general or spinal anesthesia. The surgeon makes an incision at the hip joint, removes the damaged femoral head and acetabular cartilage, and then implants an artificial hip joint prosthesis. After surgery, patients need to be observed in a rehabilitation ward for a period of time. Once their vital signs are stable, they are transferred back to a regular ward. Doctors will develop a personalized rehabilitation plan based on the patient's recovery progress, including physical therapy and rehabilitation training, to help the patient regain hip joint function as quickly as possible.

[0003] Complications of total hip arthroplasty include loosening and dislocation of the artificial acetabulum, necessitating the use of anti-dislocation devices postoperatively, such as the anti-dislocation device disclosed in publication number CN214857990U. However, current devices cannot effectively restrict leg movement, leading to excessive hip joint movement and increasing the risk of secondary hip injury. Utility Model Content

[0004] To address the problem mentioned in the background art that patients are prone to over-exertion of the hip joint, leading to secondary hip joint injury, this utility model provides the following technical solution:

[0005] A total hip replacement anti-dislocation nursing device includes a waist belt with a support plate fixed to the outside of the waist belt. Both sides of the support plate are provided with connecting plates. Leg guards are provided at the bottom of the two connecting plates and are connected by a connecting component to fix the legs.

[0006] A limiting component is provided at the connection between the support plate and the connecting plate. The limiting component includes a rotating plate fixed to one end of the connecting plate. A rotating block is fixed to the outer wall of the rotating plate. Two baffles are provided on the side of the support plate near the rotating plate. The two baffles are located on the outside of the rotating plate. By limiting the movement of the legs during the patient's walking, the walking range can be controlled to avoid excessive movement of the hip joint and to avoid secondary injury to the hip joint.

[0007] Furthermore, an annular groove is provided on the side of the support plate near the rotating plate, and two sliders are slidably arranged in the annular groove. The two sliders are respectively fixed to two baffles, and the baffles are threadedly connected with locking bolts two for fixing the baffles to the support plate, so as to facilitate the adjustment of the position of the baffles and thus the adjustment of the range of leg restriction.

[0008] Furthermore, the leg brace includes a support plate fitted onto the outer side of the other end of the connecting plate, and a leg strap is fixed to the outer side of the support plate. Both ends of the waist strap and the two ends of the leg strap are connected by Velcro.

[0009] Furthermore, the support plate is slidably connected to the connecting plate, and a locking bolt is threadedly connected to the support plate to fix the support plate and the connecting plate. The support plate can move up and down on the connecting plate, which makes it easy to adjust the height of the leg brace to meet the needs of different patients.

[0010] Furthermore, the connecting assembly includes a threaded sleeve and a threaded head that is threadedly connected to the threaded sleeve. The ends of the threaded sleeve and the threaded head that are far apart are respectively rotatably connected to a telescopic rod and a support rod. The telescopic rod and the support rod are respectively rotatably connected to the side of the two support plates that are far away from the leg straps. By connecting the two leg braces through the connecting assembly, the legs can be fixed when the patient is not moving, further avoiding secondary injury to the hip joint caused by excessive leg movement.

[0011] Furthermore, auxiliary drive components are provided on both sides of the support plate. The auxiliary drive components include a micro motor. A rectangular plug is fixed to the output end of the micro motor. A rectangular socket matching the rectangular plug is opened at the end of the rotating plate away from the support plate. When the rectangular plug is inserted into the rectangular socket, the micro motor drives the rotating plate to rotate, which helps the patient to carry out walking rehabilitation training and avoids secondary damage to the hip joint caused by the patient's early independent leg movement after surgery.

[0012] Furthermore, a support plate is fixed to the top of the micro motor, and a hollow plate is slidably provided on the outer side of the support plate away from the micro motor. A locking bolt for fixing the hollow plate to the support plate is threaded on the hollow plate. A mounting plate is fixed to the end of the hollow plate away from the support plate. The mounting plate and the support plate are detachably connected to facilitate the disassembly and assembly of the auxiliary drive component.

[0029] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0030] Please see Figures 1-3This utility model provides an anti-dislocation nursing device for total hip replacement surgery, including a waist belt 1. A support plate 2 is fixed to the outside of the waist belt 1. Connecting plates 3 are provided on both sides of the support plate 2. Leg braces 4 are provided at the bottom of the two connecting plates 3. The leg braces 4 include a support plate 41 sleeved on the outer side of the other end of the connecting plate 3. The support plate 41 is slidably connected to the connecting plate 3, and a locking bolt 43 is threaded on the support plate 41 to fix the support plate 41 to the connecting plate 3. Leg straps 42 are fixed to the outer side of the support plate 41. The two ends of the waist belt 1 and the two ends of the leg straps 42 are connected by Velcro. By fixing the waist belt 1 to the waist and the two leg straps 42 to the legs, dislocation prevention after total hip replacement surgery is achieved. Since the support plate 41 can move up and down on the connecting plate 3, the height of the leg braces 4 can be adjusted to meet the needs of different patients.

[0031] like Figures 1-2 As shown, the two leg braces 4 are connected by a connecting assembly 6 to fix the legs. The connecting assembly 6 includes a threaded sleeve 61 and a threaded head 62 threadedly connected to the threaded sleeve 61. A telescopic rod 63 and a support rod 64 are rotatably connected to the ends of the threaded sleeve 61 and the threaded head 62, respectively. The telescopic rod 63 and the support rod 64 are rotatably connected to the sides of the two support plates 41 away from the leg straps 42. After the two leg straps 42 are fixed to the patient's legs, the threaded sleeve 61 and the threaded head 62 are screwed together to restrict the movement of the two leg braces 4. This fixes the legs when the patient is not moving, preventing secondary injury to the hip joint caused by excessive leg movement.

[0032] like Figures 1-6 As shown, a limiting component 5 is provided at the connection between the support plate 2 and the connecting plate 3. The limiting component 5 includes a rotating plate 51 fixed to one end of the connecting plate 3. A rotating block 52 is fixed to the outer wall of the rotating plate 51. Two baffles 53 are provided on the side of the support plate 2 near the rotating plate 51. The two baffles 53 are located on the outside of the rotating plate 51 and are used to limit the movement of the legs. An annular groove 55 is opened on the side of the support plate 2 near the rotating plate 51. Two sliders 56 are slidably arranged in the annular groove 55. The two sliders 56 are respectively fixed to the two baffles 53 to facilitate the adjustment of the position of the baffles 53. The baffles 53 are threadedly connected with locking bolts 54 to fix the baffles 53 to the support plate 2.

[0033] Auxiliary drive components 7 are also provided on both sides of the support plate 2. The auxiliary drive components 7 include a micro motor 71. A rectangular plug 72 is fixed to the output end of the micro motor 71. A rectangular socket 57 matching the rectangular plug 72 is opened at the end of the rotating plate 51 away from the support plate 2. When the rectangular plug 72 is inserted into the rectangular socket 57, the micro motor 71 drives the rotating plate 51 to rotate, which facilitates the patient's walking training. A battery and switch can be installed on the micro motor 71 to facilitate the power supply and control of the micro motor 71.

[0034] The micro motor 71 is fixed with a support plate 73 at its top. A hollow plate 74 is slidably provided on the outer side of the support plate 73 away from the micro motor 71. A locking bolt 75 is threadedly connected to the hollow plate 74 to fix the hollow plate 74 to the support plate 73. A mounting plate 76 is fixed on the end of the hollow plate 74 away from the support plate 73. The mounting plate 76 and the support plate 2 are detachably connected by bolts or other structures to facilitate the disassembly and assembly of the auxiliary drive component 7.

[0035] When the patient is undergoing walking rehabilitation training, the rectangular insert 72 is first inserted into the rectangular slot 57 of the rotating plate 51, and then the mounting plate 76 is fixed on the support plate 2. The rotating plate 51 is driven to rotate by the micro motor 71, which in turn drives the connecting plate 3 and the leg brace 4 to rotate, thereby applying driving force to the leg rotation to assist the patient in walking and avoid secondary damage to the hip joint caused by the patient's early independent leg movement after surgery. After the patient gradually recovers, the auxiliary drive component 7 can be removed, allowing the patient to move their legs independently and improving the rehabilitation effect.

[0036] Furthermore, by rotating the baffle 53 and slider 56 along the annular groove 55, the two baffles 53 are rotated to the appropriate position. Then, the locking bolt 2 54 is tightened to fix the baffle 53. When the patient walks, the rotating plate 51 is rotated, which in turn drives the rotating block 52 on the rotating plate 51 to rotate. The rotating block 52 can only rotate to the position of contact with the baffle 53. Therefore, the walking range of the leg can be controlled to avoid the patient from over-moving the hip joint and further avoid secondary injury to the hip joint.

[0037] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
