Description

Non-binding fixing belt set for fracture

Technical Field

The invention belongs to the technical field of fracture reduction fixing tools, and particularly relates to a binding-free flexible fixing tool for a fracture part.

Background

Common surgical treatment methods for fixing fractures of femoral shafts and the like include steel plate fixing and intramedullary nail fixing, the steel plate fixing has the advantages of simple operation, short learning period, large wound, high accidental injury probability, more required matching models, infection, non-healing, delayed healing, nail and plate fracture sometimes, large postoperative scar, beautiful influence and non-compliance with the minimally invasive principle. The intramedullary nail adopts a closed and minimally invasive technology, the locked intramedullary nail can prevent the rotational deformity of the fracture, reduce the risk of the fracture of the built-in object, reduce the infection rate of the operation, promote the high healing rate of the fracture, avoid the stress shielding effect by central fixation and have low incidence rate of the re-fracture. The intramedullary nail mode accords with the minimally invasive principle, is the current development direction, but is difficult to operate and learn, the intramedullary nail distal end is difficult to lock, the reduction part is closed and limited incision is performed, but the intramedullary nail distal end is not anatomically reduced, the healing is delayed, and the pressure of a patient is higher. Complications such as abnormal healing and poor lower limb force lines may occur after surgery. Because the intramedullary nail is in a linear type fixing mode, the intramedullary nail fixing mode cannot be well solved aiming at special bones with large curvature, such as clavicle, radius and the like. Moreover, the problem of bone resorption exists in the recovery period after the butt joint of the fractured bones, which affects the normal recovery.
