Description

Elbow joint brace capable of adjusting forearm rotation angle

Technical Field

The utility model relates to the field of medical treatment of bone surgery, in particular to an elbow joint support capable of adjusting the rotation angle of a forearm.

Background

At present, the ratio of patients with olecranon fracture or radius small head fracture in the bone surgery is very high, and the fracture position can be basically healed at 6-8 weeks after the internal fixation operation, but as the upper limbs of early patients are in a braking state after the operation, most of forearms of the patients in the braking state are placed at the bedside or elbow bend and put on the body in a pronation state, and the joints can be adhered or even contracture at different degrees about 2 weeks generally. At present, a lot of elbow joints are available on the market, the elbow joint bending and stretching activity degree of the patient is obviously improved, but the type of elbow joint bending and stretching activity degree has the defect that the forearm rotation problem cannot be improved, so that a lot of patients can find that the fracture healing is good when one and a half go to an orthopedics outpatient examination after operation, the elbow joint bending and stretching function can basically achieve life self-care, but the forearm rotation function has a great obstacle, the actions of twisting towels, stretching hands to receive things, feeding to the mouth after dish clamping, making calls and the like cannot be smoothly performed, the life quality of the patient is seriously influenced, and particularly the influence on the young patients who engage in manual aspects is larger. In addition, for hemiplegic patients, no matter in the early stage, the upper limbs on the hemiplegia side are in a supination state and are placed at the bedside or bend elbow to be placed on the body, and the state can also cause dysfunction of the forearm on the affected side to different degrees, so that the difficulty of later functional rehabilitation is increased. For this purpose we propose an elbow joint brace with adjustable forearm rotation angle to solve the above problems.

Chinese patent document CN 214908828U describes an elbow joint brace with cold stimulation function, comprising upper arm cold compress equipment, forearm cold compress equipment, elbow joint cold compress bag, support fixing rod; the supporting and fixing rod comprises an upper arm telescopic rod and a forearm telescopic rod; the upper arm telescopic rod and the forearm telescopic rod are rotationally connected through an elbow joint part; the upper arm cold compress device is arranged on the upper arm telescopic rod; the forearm cold compress device is arranged on the forearm telescopic rod; the elbow joint cold compress bag is arranged on the elbow joint part; the upper arm cold compress device and the forearm cold compress device are electrified and started through the power connector. The device is used for carrying out temperature-controllable ice compress detumescence on the elbow joint when the elbow joint is fixed at the early stage of fracture, and is convenient to detach. However, the forearm of the device can not rotate, which directly leads to the actions of twisting towels, stretching hands to receive things, feeding dishes to the mouth after clamping dishes, making calls and the like, thus seriously affecting the life quality of patients, and particularly having larger influence on young patients who are engaged in manual work. The use has drawbacks and needs improvement.
