Description

Inflatable shoulder joint fixing brace

Technical Field

The invention belongs to the field of medical instruments, and particularly relates to an inflatable shoulder joint fixing brace.

Background

Shoulder joint diseases occupy an important position in the department of sports medicine, shoulder joint diseases are treated in the third place in outpatient service of sports medicine, and main diseases of shoulder joints comprise shoulder sleeve injury, shoulder joint dislocation, fracture and the like.

(1) Rotator cuff injury

The movement of the shoulder joint depends on the traction and the cooperation of muscles, the rotator cuff makes tendons thickened around the shoulder joint to surround the proximal part of the humerus, muscle strength can be transmitted to bones through the rotator cuff to generate movement, so that the rotator cuff is degenerated or can cause rotator cuff injury under the condition of external force, for example, the rotator cuff injury can be caused by slight trauma of old people, accidental injury of young people and the like. After the rotator cuff is damaged, the damaged split is mainly repaired through an operation, the rotator cuff part needs to be fixed to repair the rotator cuff after the operation, and the rotator cuff needs to be fixed through a bracket for about 3 months generally.

(2) Dislocation of shoulder joint

Dislocation of the shoulder joint refers to dislocation, i.e. the change of the normal position of the joint, the most important injury of dislocation is soft tissue injury around the joint, and the dislocation can be developed into habitual dislocation, i.e. repeated dislocation without proper treatment. The primary injury of shoulder joint dislocation is that the joint capsule around the shoulder joint is seriously torn and the soft tissue is loosened in the case of external injury, and the repeated dislocation patients still have the looseness, so the main method in treatment is the tightening and overlapping repair of the joint capsule, even the repeated dislocation causes the bone to be worn out, so bone surgery is needed, the shoulder fixation is needed after the bone surgery to ensure the tissue to grow and heal, and the process needs to be fixed by using a support, generally about 3 months.

(3) Fracture of bone

The fracture around the shoulder joint mainly comprises: humerus surgery neck fracture, humerus anatomy neck fracture, proximal humerus fracture, scapula fracture, clavicle fracture and the like, and the treatment of these fractures, whether conservative treatment or surgical treatment of the fracture, requires postoperative fixation with a brace, especially for conservative treatment patients, because there is no way to stably fix the fracture at this site by plaster fixation, the brace becomes the most important and most commonly used tool.

The shoulder joint brace needs to satisfy the supporting and fixing functions, and common braces in the prior art comprise a fixed hand and elbow support, a non-adjustable brace (commonly called a small sofa), an adjustable metal fixed brace and the like. Wherein, fixed hand elbow support is hand elbow support promptly, and the characteristics of fixed hand elbow support include: the angle of the shoulder joint cannot be fixed, the protection performance is poor, the main function is only lifting or simple fixing, the use is convenient, the wearing is simple, and the technical content of the production is low. Is mainly suitable for conservative treatment of shoulder joint fracture operation (except soft tissue), clavicle fracture operation, scapula fracture operation, primary shoulder joint dislocation operation, slight shoulder joint fracture and the like. The non-adjustable brace (commonly called as a small sofa) is characterized by being capable of keeping a shoulder joint at a certain angle, having a lifting function, mainly applied to shoulder joint soft tissue operations (such as rotator cuff injury and shoulder joint dislocation) and being nonadjustable in angle. The adjustable metal fixing brace is characterized in that: the fixation strength is high, and the bone fracture fixation device is used for fixing bone fracture before and after operation; the metal material can adjust the abduction angle; the bearing is not carried in the axial direction due to no lifting function; the metal material is heavier and has poorer comfort; the elasticity is poor, and the local part generates indentation or pressure sore after long-term use; it is inconvenient to carry and heavy.

The disadvantages of the existing brace are as follows: 1. a part of the braces only have a fixing function and are weaker in body position maintaining and strength; 2. part of products can be maintained in a specific body position, have a protection effect at the same time, have a lifting and pressure reducing effect in the axial direction, protect joints, but cannot adjust the angle along with the disease condition; 3. the brace with partial metal design can be used for angle adjustment, but has the advantages of rough working, heavier weight, poorer elasticity and poor comfort, does not have axial lifting function, and cannot reduce the pressure of the joint. The main reason for the above characteristics is that the above designs are not related to the treatment characteristics of the main diseases of the shoulder joint of the human body and the biomechanics characteristics of the human body, cannot be designed and improved in the aspects of angle adjustment, strength support in various directions and the like, cannot completely meet the actual clinical needs, and simultaneously is deficient in consideration of comfort in design.
