Description

A passive hip joint limiting aid

technical field

The invention relates to the field of medical instruments, in particular to a passive hip joint limiting aid.

Background technique

The hip joint plays a linking role in the lower limbs and upper body. It is the main force point for lower limb support and walking. It is of great significance to the activities of the lower limbs of the human body. During the treatment of femoral head and neck fractures, trochanteric fractures of the femoral head, hip dislocation, hip replacement, etc., the patient stays in bed for a long time, it is difficult to walk on the ground, and the range of motion of the hip joint is limited. In order to solve the above problems and inconveniences, and at the same time to improve the effective utilization rate of hospital beds, a passive hip joint auxiliary supporter that conforms to the human body space curve is developed and researched.

SUMMARY OF THE INVENTION

The present invention is aimed at patients with hip joint problems or hip joint treatment, and provides them with a hip joint limiting auxiliary device for sharing the load of the hip joint.

The technical scheme adopted in the present invention is: part of the weight of the upper body is transferred to the leg belt through the waist belt, thereby reducing the stress on the hip joint. In order not to affect the rotation of the hip joint, a hinge structure is designed on one side of the hip joint. In order to achieve a good support effect and reduce the impact of walking at the same time, an adjustable spring structure is added to the hip joint auxiliary supporter, and the spring preload is adjusted while adjusting the overall length of the hip joint auxiliary supporter to achieve the matching of different body heights. . In order to achieve the comfort of use, the overall space curve of the support frame of the hip joint auxiliary supporter is designed according to the space curve of the human body, which is basically consistent with the space curve of the human body.

The waistband and leg straps are made of sponge core, the outer wrapping material is linen, and nylon buckles are used as connecting devices to achieve the comfort of contact with the human body and the convenience of attaching and detaching the hip joint auxiliary support; the waistband and the waist plate are connected by rivets at the same time. The connection, the leg strap and the leg plate are connected, and the passive hip joint auxiliary supporter and the human body are connected through the waist belt and the leg strap, so that a part of the upper body weight is transferred to the leg strap through the waist belt to achieve the auxiliary support. effect.

The upper connecting plate is connected with the waist plate by rivets, and adopts a rigid connection, so the two cannot be rotated; the upper connecting plate is connected with the upper cover plate through the connecting hinge copper column, and they are connected by a rotating pair, and the two can be rotated; The front edge of the cover plate rotation has a 40° rib, and the rear edge has a 30° rib, which limits the range of rotation. The upper connecting plate can only rotate 40° forward or 30° backward around the upper cover plate, so as to limit the hip joint. The angle of the back and forth swing. The support frame can only rotate at the hinge in the sagittal plane of the human body, and the angle of rotation is limited, which fully limits the forward and backward movement of the hip joint. At the same time, the support frame is rigid as a whole in the lateral direction, which fully limits the lateral swing and adduction movement of the hip joint.

The rotating handle is connected by the rotating handle connecting column and the threaded stud; the rotating handle connecting column fixes the bearing at the specific position of the rotating handle connecting column through the upper and lower bearing inner blocks; at the same time, the upper cover plate and the bearing lower cover plate limit the bearing. Position; in combination, the rotation of the threaded stud with self-locking capability is achieved by turning the handle. The two spring columns are connected by a spring column connector and a threaded stud. The bottom end of the spring column is in contact with the spring. The rotation of the threaded stud drives the spring connector to move up and down, so as to adjust the overall size and preload of the passive hip joint auxiliary supporter. The effect of force, so that it can be applied to people of a certain height. The spring is at the bottom of the telescopic cavity, and the telescopic cavity and the front and rear plates limit the farthest position of the telescopic cavity and the connecting hinge through the end limit boss, which fully limits the size adjustment range of the passive hip joint supporter.

The expansion cavity is connected by rivets through the lower connecting plate and the leg plate, and the three can not be rotated between each other, which fully guarantees the rigidity of the support frame.

The beneficial effects of the present invention are: aiming at the problem of difficulty in walking of patients after the repair of intertrochanteric and greater trochanteric fractures, providing hip joint limit and appropriate hip joint auxiliary support for patients to walk after wearing, and significantly reducing the complications of bed rest after surgery At the same time, it provides safe exercise, increases the patient's immunity, and accelerates the recovery of the disease.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings.

The exemplary hip joint limiting aid is worn on the left foot, and the principle of wearing on the right foot is similar, and the two are symmetrical with respect to the sagittal plane of the human body.

As shown in Fig. 1, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, this example provides a passive hip joint limiting aid, including: a belt A, a support frame B, and a leg belt C, all of which are The support frame B includes a waist plate B1, an upper connecting plate B2, a connecting hinge B3, a connecting hinge baffle B3-1, a connecting hinge copper column B3-2, a rotating handle B4, a rotating handle connecting column B5, a bearing inner stop B6, a bearing B7, upper cover plate B8, bearing lower cover plate B9, threaded stud B10, spring column connector B11, spring column B12, side plate B13, spring B14, telescopic cavity B15, lower connecting plate B16, leg plate B17, front and rear plates B18, end limit boss B19.

The passive hip joint auxiliary supporter can extremely fit the human body space curve and achieve the effect of wearing comfort. The adjustment of the size of the auxiliary hip joint supporter and the adjustment of the pre-tightening force of the auxiliary hip joint supporter can be realized by rotating the rotary handle, so as to achieve the optimal supporting effect.

In this example, the passive hip joint auxiliary supporter is fastened to the waist by a waist belt, and is fastened to the legs by a leg belt, and is used for walking after adjusting the preload force and the length of the supporter. When standing, the weight of the upper body is transmitted across the hip joint to the lower part of the thigh through the supporter to achieve the effect of auxiliary support.

In this example, the entire front of the passive hip joint auxiliary support frame is only rotatable at the hinge, and the rotation angle is limited, which fully limits the forward and backward movement of the hip joint. At the same time, the support frame is rigid as a whole in the lateral direction, which fully limits the lateral swing and adduction movement of the hip joint. The movement of the lower extremity wearing the support is sufficiently restricted.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
