Description
Technical Field
The invention relates to the field of medical instruments, in particular to an adjustable fixing support.
Background
Developmental hip dysplasia (DDH) is one of the most common bone joint deformities in infants. For infants older than 6 months or failed initial brace treatment, a "closed reduction + hip fixation" treatment regimen is commonly used clinically. The proposal can maintain the stable reduction of the femoral head in the acetabulum by forcedly fixing the hip joint in a specific human body position (namely, high buckling and abduction position), thereby creating a mechanical environment for the normal development of the acetabulum.
However, the traditional hip-herringbone gypsum has a plurality of inherent defects, which seriously affect the treatment effect, the comfort of the children and the home care experience:
The fixation is stiff and cannot be adjusted, and once the gypsum is solidified and molded, the fixed angles of the hip joint and the knee joint cannot be changed. In the whole treatment period up to several months, fine adjustment at any angle cannot be performed according to the change of the resetting stability or the growth and development of the child, and individuation and adaptability are lacking.
The nursing is difficult, the risk of complications is high, gypsum materials are heavy and airtight, and the gypsum materials cannot be disassembled, so that the skin of an infant is difficult to clean, and eczema, pressure sores and even infection are extremely easy to cause. In addition, the thick gypsum severely hampers the daily activities of the child, the sleeping and the caring work of the parents.
The growth and review are hindered, the infant grows rapidly, the fixed gypsum tube is often rapidly tightened due to thickening and lengthening of the limb, the blood circulation of the limb is possibly affected, the growth must be adapted by complete disassembly and remanufacturing, the process is tedious, and the pain of the infant is increased. Meanwhile, gypsum causes serious interference to X-ray images, and accurate assessment of reset quality by doctors is affected.
To overcome the shortfall of gypsum, some adjustable brace devices have been developed in the prior art. However, these devices typically provide only limited, coarse angular adjustment functions (e.g., if a gear is engaged), and lack a precise, continuous, and quantifiable angular adjustment mechanism. The adjusting process often depends on experience hand feeling of doctors, accurate angle setting and reproduction based on imaging review results cannot be achieved, and stability and reliability of the joint locking structure after adjustment are insufficient. In addition, the prior adjustable brace has obvious defects in the aspects of ventilation, light weight and intelligent monitoring.
Therefore, in order to solve the problem that the angle cannot be adjusted, the invention designs an adjustable fixing support to adjust the angles of the hip joint and the knee joint of the related support.

Firstly, adjusting a knee joint adjusting part, firstly, adjusting a limiting part in a limiting state, and then enabling a second spring to be compressed by a clamping ring on a first pushing part to be in a tightening state by pressing down the first pushing part, wherein the second pushing part is pushed to the depth of a first opening in a first fixing part, at the moment, loosening the first pushing part, the second spring rebounds and drives the first pushing part to move upwards, and drives the second pushing part to extend out of the first opening, at the moment, a clamping block meshed with a third sawtooth is correspondingly lifted, at the moment, the knee joint adjusting part is in a rotatable state, at the moment, the second sawtooth outside the knee joint adjusting part drives the meshed first sawtooth to rotate by rotating along a groove, and then drives the first connecting part to rotate, so that the knee joint angle adjustment is realized, after the knee joint angle adjustment is finished, the first pushing part in the limiting part is pushed downwards, and then the second pushing part on the limiting part is pushed into the first fixing part to stretch into the first opening of the knee joint, and the adjustment is realized, and the adjustment of the knee joint angle is realized; when the angle of the hip joint brace is adjusted, the hip joint adjusting part is required to be adjusted, the adjusting part is firstly rotated and adjusted, the adjusting part in a pressed state is rotated, the adjusting part is adjusted to be in a lifting state because the adjusting part rotates around an eccentric screw, at the moment, the adjusting part does not press the upper rotating part, so the upper rotating part is lifted upwards by the third spring, the upper rotating part is far away from the lower rotating part meshed with the upper rotating part, the lower rotating part can rotate around the supporting column, and the lower rotating part is connected with the connecting part, so that the connecting part is driven to adjust the angle, the thigh support is driven to rotate, the angle between the thigh support and the hip joint support is adjusted, after the adjustment is finished, the adjusting part rotates, the adjusting part returns to a downward pressing state, the upper rotating part is pressed down to a position meshed with the upper rotating part, the lower rotating part cannot rotate, the adjusting part is fixed through a first screw hole in the screw-in supporting column, rebound of the adjusting part is avoided, and the adjustment of the angle of the hip joint support is realized.
In summary, the traditional fixing support is improved, so that in the correction process by using the support, a doctor can adjust the knee joint and hip joint angles of the support according to the recovery condition, the support is prevented from being disassembled, and the multi-angle adjustment of the traditional fixing support is effectively realized.
