Description

Pillow for turning over after hip joint replacement

Technical Field

The utility model belongs to the technical field of surgery postoperative care, concretely relates to pillow stands up after hip joint replacement art.

Background

Osteoarthritis (OA) is a chronic degenerative disease of the joints characterized by cartilage degradation, bone remodeling, osteophyte formation, joint inflammation, and loss of normal joint function. Its clinical manifestations are mainly local pain and limited mobility of the joints. OA is a common disease in the middle-aged and elderly, which is better in women over 55 and men over 65. As the economy progresses and the population ages, the number of patients with osteoarthritis continues to increase. Osteoarthritis is considered one of the most common diseases that are globally disabling. In 2018, royal and et al found that KOA prevalence in china is as high as 18% and the burden of the disease is heavy by meta analysis of data of more than 20 years. The clinical treatment is usually performed by an operation, and the operation mode is generally artificial joint replacement operation.

Demos et al report that the initial THA postoperative dislocation rate is 3.2% -6.5% and the revision postoperative dislocation rate is 7.4% -11.4%. Wherein, part of dislocation is postural dislocation: the prosthesis is correctly positioned, the soft tissues are balanced, and dislocation is caused by improper movement of the affected limb. Dorr et al classify THA post-operative dislocation into four categories, category I: postural dislocation: the prosthesis is correctly positioned, the soft tissues are balanced, and dislocation is caused by improper movement of the affected limb. And II: the unbalanced dislocation of soft tissues comprises a high acetabular cup, excessive osteotomy of femoral neck, short femoral neck and the like. Class III: malposition of the prosthesis. Including placement errors in the position and orientation of the cup and femoral stem prosthesis. And IV: there is a combination of soft tissue imbalance and malposition of the prosthesis. Postural dislocation is often caused by early improper activity after surgery. Therefore, how to guide and help the patient to move early after the operation can effectively reduce the dislocation probability after the hip replacement.

At present, the symptomatic treatment aiming at postural dislocation is mainly achieved by means of postoperative guide activities, methods of forbidding squat, lifting legs, and the like. When the patient turns over in the early period after operation, the patient usually turns over after a pillow is filled between the two knees to avoid the over internal rotation of the hip joint, thereby causing the dislocation of the hip joint. However, the pillow is placed incorrectly and still in an over-pronated position after the pillow is placed, which results in a dislocation after the hip joint operation, because the patient or family members are not fully understood.

The existing turning-over pillow adopts a trapezoidal design with a short upper part and a long lower part. Mainly considering knee joint postoperation, in order to prevent complications such as bedsore after the operation, the turning-over time may need to be longer than half an hour. The turning-over pillow with the trapezoidal design needs assistance of family members of a patient (the patient does not slide out of the periphery of the turning-over pillow by holding the affected limb), and is more suitable for turning over during short-time operation such as bed-crossing.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a pillow for turning over after hip joint replacement, which can effectively reduce the dislocation of the position after hip joint replacement caused by improper activity after the operation.

In order to achieve the above object, the utility model provides a pillow stands up after hip joint replacement art, including last top surface, bottom surface, shank fixed slot and the buckle that flexible material made, the buckle is equipped with the multiunit, and the upper and lower part of every group buckle is fixed respectively on last top surface and bottom surface down, and the shank fixed slot is between last top surface and bottom surface down.

Furthermore, the vertical section of the utility model is in the shape of an I.

Furthermore, two leg fixing grooves are arranged, the cross sections of the leg fixing grooves are similar to a circle, and the diameter of the similar circle is 13-18 cm.

Further, the upper top surface and the lower bottom surface have a length of 50-70cm and a width of 30-45 cm.

The distance between the upper top surface and the lower bottom surface is 15-25 cm.

Further, the buckle is provided with 2-5 groups.

Further, the device comprises a fixing rope belt, and the fixing rope belt is wound in a crossed mode.

Compared with the prior art, the utility model provides a pillow stands up after hip joint replacement art, the shank fixed slot adopts the circular design of class more to accord with human both legs structure, can make the limb of suffering from wrap up in comparatively soft pillow completely, can not make patient experience discomfort because of the time overlength, also need not the people to hold up the limb of suffering from and prevent to suffer from the limb roll-off from shorter one side. The multiple groups of buckles fix the thighs and the shanks at the two sides, so that the moving range of the double-knee joints is limited, and the phenomenon that the double-knee joints are crossed due to improper movement during turning over, so that the excessive internal rotation of the hip joints is caused, and the dislocation of the hip joints is caused is avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment of the utility model provides a pillow stands up after hip joint replacement art, including last top surface 1, lower bottom surface 2, shank fixed slot 3 and the buckle 4 that flexible material made, buckle 4 is equipped with the multiunit, and 4 upper and lower parts of every group buckle are fixed respectively on last top surface 1 and lower bottom surface 2, and shank fixed slot 3 is between last top surface 1 and lower bottom surface 2.

By adopting the structure, the upper top surface 1 and the lower bottom surface 2 form the fixed supporting effect on the leg fixing groove 3, so that the affected limb can be completely wrapped inside the soft leg fixing groove 3, the patient can not feel discomfort due to overlong time, and other people are not required to hold the affected limb to prevent the affected limb from sliding out from the shorter side, so that the hip joint is damaged. The plurality of groups of buckles 4 fix the thighs and the shanks at the two sides, so that the moving range of the double-knee joints is limited, and the phenomenon that the double-knee joints are crossed due to improper movement during turning over, so that the excessive internal rotation of the hip joints is caused, and the dislocation of the hip joints is caused is avoided.
