Description

Rehabilitation device used after operations such as lower limb fracture and joint replacement

Technical Field

The invention relates to the technical field of medical instruments, in particular to a rehabilitation device used after operations such as lower limb fracture, joint replacement and the like.

Background

Lower limb fractures are mostly caused by external violence, and no matter the internal fixation or external fixation operation is adopted for treatment, the fractured and displaced bone blocks are usually fixed by adopting metal material (steel or titanium) plates and screws, so that the patients are helped to recover the bony anatomical structures and the vertical lines as early as possible, the early activity capability of the patients after the fracture operation is recovered, and the original functions of the related joints of the lower limbs are kept. Similarly, joint replacement surgery is also a common orthopedic treatment at the end of severe osteoarthritis, simply by removing the long-term degenerative and severely damaged facet of the joint and the underlying facet portion in place of an artificially designed prosthetic component. Each step in the joint replacement procedure is to take into account whether the function concerned is affected, whether the endoprosthesis is suitable, and whether the stability after fixation is sufficient, etc., and to ensure that the patient can resume his normal movement after the procedure.

Therefore, rehabilitation exercise after the operation is also very important, which directly influences the occurrence of secondary injuries such as thrombosis and other complications of patients, local soft tissue swelling and necrosis and the like. It is known that the flexion and extension functions and muscle strength of the lower limbs are important bases for ensuring independent walking in daily life and are clinical responses of the overall recovery curative effect after orthopedic surgery. The aim of knee joint rehabilitation training in clinic is to keep the range of motion of the knee joint after operation, such as flexion, extension, rotation and the like, so as to keep the living needs. The slowing of blood flow in the lower extremities caused by the braking department is also one of the factors of the deep vein thrombosis of the lower extremities.

However, after the operation, the patients have inflammatory reaction after the soft tissues such as muscles are incised and sutured and the local trauma occurs, the soft tissues are usually quite painful, the rehabilitation exercises such as joint movement and the like cannot be automatically completed, the patients often need medical, technical and nursing staff to assist the rehabilitation treatment, and the requirements on experienced professional rehabilitators are large. Due to serious shortage of rehabilitation therapists, many primary hospital orthopedics usually replace the work of the rehabilitation therapists by nurses who are simply trained. However, professional differences and the lack of standardization of rehabilitation therapy often lead to the conditions that the pain of patients is aggravated and the risk of re-fracture is caused due to simple and violent exertion of non-professional therapists, the compliance of the patients is poor, and the postoperative disability reduction rate cannot reach the ideal rate.

Disclosure of Invention

The invention aims to provide a rehabilitation device used after operations such as lower limb fracture, joint replacement and the like, which solves the problem that patients with lower limb fracture and joint replacement in the background technology are inconvenient to exercise independently.

The technical purpose of the invention is realized by the following technical scheme: a rehabilitation device used after operations such as lower limb fracture, joint replacement and the like comprises a panel, a supporting frame is arranged below the panel, the middle part of the panel is provided with a first groove and a second groove which are communicated with the first groove, a rotating plate is rotatably connected in the first groove, a first sliding groove is jointly formed in the first groove and the second groove, a lead screw is rotationally connected in the first sliding groove, a first sliding block and a second sliding block are connected on the lead screw in a threaded manner, the first sliding block and the second sliding block are both connected in the first sliding groove in a sliding way, the first sliding block is rotatably connected with a supporting rod, one end of the support rod, which is far away from the first slide block, is rotatably connected to the lower side wall of the rotating plate, a placing groove is formed in the second groove, a bending and stretching air bag is arranged in the placing groove, a sealing plate is fixedly connected to the second sliding block, and the sealing plate is connected in the second groove in a sliding manner; a power cavity is formed in the panel, one end of the lead screw penetrates into the power cavity, a first bevel gear positioned in the power cavity is arranged on the lead screw, a connecting rod is connected in the panel in a rotating mode, one end of the connecting rod penetrates into the power cavity, a second bevel gear positioned in the power cavity is arranged on the connecting rod and is connected with the first bevel gear in a meshed mode, a turntable positioned outside the panel is fixedly connected to the other end of the connecting rod, and a handle is arranged on the turntable; and an inflation mechanism for inflating the flexion-extension air bag is arranged on one side of the panel, and an air release valve for releasing the flexion-extension air bag is arranged on the other side of the panel.
