Knee joint moving device for leg fracture

Abstract

The present invention discloses a knee joint moving device for a leg fracture, which comprises a bottom plate, a fixed plate and a moving plate. Side boards are arranged at both sides of the upper plate surface of the bottom plate; both the side boards are provided with chutes; two ends of the fixed plate are respectively connected with the bottom plate and the moving plate; the moving plate is connected with the side boards; one row of clamping grooves A are respectively formed at each of both sides of the central line of the upper plate surface of the fixed plate; slidable first left hoops are assembled in the clamping grooves A positioned at one side of the central line; slidable first right hoops are assembled in the clamping grooves A positioned at the other side of the central line; the first left hoops and the first right hoops are matched; one row of clamping grooves B are respectively formed at each of both sides of the central line of the upper plate surface of the moving plate; slidable second left hoops are assembled in the clamping grooves B positioned at one side of the central line; slidable second right hoops are assembled in the clamping grooves B positioned at the other side of the central line; and the second left hoops and the second right hoops are matched. According to the knee joint moving device, a knee joint can do proper exercise on the premise of not drawing a fracture part.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a knee joint movable device for leg fractures. Background technique [0002] Leg fractures are fractures with a high incidence rate. Leg fractures usually include: lower femur fractures, femoral condyle fractures, patella fractures, tibial plateau fractures, proximal fibula fractures, upper tibial fractures, and tibial tuberosity avulsion fractures. After a fracture, it is generally necessary to perform reduction and fixation first, and then mainly bed rest. And because fractures are different from general skin and muscle injuries, the healing time of hard bone is relatively long, which can be as short as 1 month and as long as more than half a year. Long-term bed rest, the knee joint cannot be moved, will cause joint adhesion, joint stiffness, and serious joint dysfunction; and joint movement will affect the leg, if a little improper force will cause Fracture displacement.

Problems solved by technology

Long-term bed rest, the knee joint cannot be moved, will cause joint adhesion, joint stiffness, and serious joint dysfunction; and joint movement will affect the leg, if a little improper force will cause fracture displacement

It needs to be reset and fixed again, which increases the pain of the patient
