Description

An intelligent support for hip fracture

technical field

The invention relates to the technical field of medical devices, in particular to an intelligent brace for hip joint fractures.

Background technique

Hip fracture is a common disease in orthopaedics. After the occurrence of hip fracture, the common treatment methods include plate, intramedullary nail and joint replacement. For patients treated with plates and intramedullary nails, they need to be immobilized in bed after surgery, and can gradually bear weight until the fracture heals.

However, in the traditional rehabilitation process, it is difficult for many patients to receive adequate rehabilitation guidance. Premature and excessive weight bearing may lead to secondary fractures, while some patients are afraid of secondary fractures caused by weight bearing, which may lead to late landing and poor functional recovery. , the existing rehabilitation aids need to consume a lot of the patient's strength during the recovery and use of the patient, and also test the patient's physical ability to use strength continuously. This requirement has great psychological pressure, especially for the elderly, and the body is also difficult Coping well. Therefore, how to help patients recover early, reduce their physical energy consumption, and achieve good disease recovery and functional exercise through the innovation of auxiliary braces, so that auxiliary braces can not only be suitable for ordinary young patients, but also adapt to the elderly. Rehabilitation training is the pursuit of orthopedic surgeons.

At present, the emergence of technologies such as exoskeletons provides solutions to the above problems.
