Description
Technical Field
The utility model belongs to the technical field of medical instrument and specifically relates to a spacing supplementary eyelidretractor of passive hip joint.
Background
The weight of the upper half of the body is transmitted to the lower limbs through the hip joints, which affect the walking, running, jumping, etc. of the body. After a fracture patient is repaired by an operation such as a bone fracture plate, an intramedullary nail and the like or the hip joint of the patient is replaced, the hip joint of the patient cannot bear overlarge load for safety; meanwhile, a bed for long time will affect the recovery of the body. Therefore, a passive hip joint limiting auxiliary support is needed to be developed to help a patient get up for safe exercise, so that the weight of the human body can be supported, and the movement range of the hip joint can be limited.
SUMMERY OF THE UTILITY MODEL
The utility model provides a hip joint limiting auxiliary device for sharing the load of the hip joint for the patients who have the problem of the hip joint or the patients who have the hip joint for treatment.
The utility model adopts the technical proposal that: the waist thermoplastic plate at the upper part of the limiting rod is fixed with the upper body of the human body, the leg thermoplastic plate at the lower part of the limiting rod is fixed with the legs of the human body, and the movement range of the hip joint of the human body is limited through the hip hinge, so that the purpose of limiting is achieved. The foot rest of the supporting rod is connected with the foot plate of a human body, the upper end of the supporting rod is connected with the support, when the supporting rod needs to bear weight, the human body presses the support with the weight of the first half through the armpit, the weight is transmitted to the foot rest through the supporting rod, and finally the weight is transmitted to the ground.
In order to improve the wearing comfort and the disassembly convenience, the sponge inner cores are pasted inside the waist thermoplastic plate and the leg thermoplastic plates, so that the contact area with the human body is increased; the waist thermoplastic plate, the leg thermoplastic plates and the foot supports are fixed with the body parts and the feet of the human body by sponge nylon belts and bayonets.
The limiting rod spherical hinge pair is specially designed and consists of a waist rod, a hip hinge and a hip hinge sleeve, and the motion range of the hip hinge is limited by the special shape of the hip hinge sleeve; through design, the spherical hinge pair can limit the movement of the hip joint, the forward swing is 30 degrees, the backward swing is 7 degrees, the abduction is 10 degrees, the adduction is 7 degrees, and the movement beyond the range is limited. The support spherical hinge pair of the support rod consists of a support, a support hinge and a support hinge cover, and the movement range of the spherical hinge pair is 30 degrees in front swing, 30 degrees in back swing, 30 degrees in abduction and 30 degrees in adduction; the foot support spherical hinge pair of the supporting rod consists of a foot support, a foot support hinge and a foot support hinge cover, and the motion range of the spherical hinge pair is 30 degrees in front swing, 30 degrees in back swing, 30 degrees in abduction and 30 degrees in adduction; the two spherical hinge pairs increase the compatibility of the movement of the supporting rod and the movement of the human body, and the effect of increasing the wearing comfort level is achieved.
The relative position of the lower loop bar and the lower slide bar is changed, thereby adapting to the change of the linear distance between the sole and the armpit when the human body walks. When a human body is upright, the straight line distance from the armpit to the sole is the sum of the leg length and the body length increased by the shank length, and the distance between the armpit and the sole is the longest; when a human body walks, the hip joint is bent, the knee joint is bent, and the shortest straight-line distance from the armpit to the sole can be deduced from the fact that the sum of two sides of the triangle is larger than that of the third side. The change range of the straight line distance between the armpit and the sole needs to be equal to the moving range of the lower loop bar and the lower slide bar sliding pair, so that the geometrical parameters of human walking are met, and the wearing comfort is ensured.
The utility model has the advantages that: aiming at the problem that the patient is difficult to walk after the bone fracture repair of each part of the femur is fixed by an intramedullary nail or a bone plate, the hip joint limiting and reliable hip joint support is provided for the patient to walk after being worn, the time for the patient to lie in bed is reduced, the incidence probability of complications of the patient to lie in bed after the operation is reduced, the activity of the patient is increased, the immunity of the patient is increased, and the recovery of the state of an illness is accelerated.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The exemplary spacing auxiliary support is worn by the left foot, the principle of wearing by the right foot is similar, and the two are symmetrical about the sagittal plane of the human body.
As shown in fig. 1, 2 and 4, the present example provides a passive hip-limiting auxiliary support, comprising: comprises a support rod (A), a limiting rod (B) and a support (C); the support rod (A) comprises a support hinge cover (A1), a support hinge (A2), an upper sliding rail (A3), an upper sliding rod (A4), a lower sleeve rod (A5), a lower sliding rod (A6), a foot support hinge (A7), a foot support hinge cover (A8) and a foot support (A9); the supporting rod (A) comprises a chest rod (B1), a waist thermoplastic plate (B2), a waist rod (B3), a hip hinge sleeve (B4), a hip hinge (B5), a leg rod (B6) and a leg thermoplastic plate (B7); the supporting rod (A) and the limiting rod (B) are connected into a whole through the support (C), the supporting rod (A) realizes the supporting function, and the limiting rod (B) realizes the function of limiting the movement range of the hip joint. The principle of wearing the auxiliary spacing support device on the left foot and the right foot is similar to the principle of wearing the auxiliary spacing support device on the right foot in the figure, and the two are symmetrical about the sagittal plane of a human body.
In the example, the inner walls of the waist thermoplastic plate and the leg thermoplastic plates can be provided with the sponge inner core according to actual needs, so that the contact area between the thermoplastic plates and the human body is increased, and the wearing comfort is improved; the sponge nylon belt is connected with the human body through the edge square holes of the waist thermoplastic plate and the leg thermoplastic plates, the sponge nylon belt is connected with the human body foot plate through the edge square holes of the foot supports, and the connecting mode adopts a buckle and a magic tape; the waist thermoplastic plate is firmly connected with the chest and the waist of the human body, the leg thermoplastic plate is firmly connected with the legs of the human body, and the foot support is firmly connected with the foot plate of the human body, so that the wearing of the hip joint limiting auxiliary support is realized.
