Systems and methods for internal bone fixation

Abstract

Internal bone fixation devices and methods for using the devices for repairing a weakened or fractured bone are disclosed herein. According to aspects illustrated herein, there is provided a device (700) for repairing a fractured bone that includes a delivery (710) having an elongated shaft (701) with a proximal end, a distal end, and a longitudinal axis therebetween, the delivery catheter (710) having an inner void (713) for passing at least one reinforcing material, and an inner lumen (711) for accepting a light pipe (652), wherein a distal end (723) of the inner lumen (711) terminates in an optical lens (754); a conformable member (703) releasably engaging the distal end of the delivery catheter (710), the conformable member (703) moving from a deflated state to an inflated state when the at least one reinforcing material is delivered to the conformable member (703); and an adapter releasably engaging the proximal end of the delivery catheter (710) for receiving the light pipe (652) and the at least one reinforcing material.

Description

Technical field [0001] The embodiments disclosed herein relate to medical devices for repairing weakened bones or fractured bones, and more specifically, to internal bone fixation devices and methods of using these devices to repair weakened or fractured bones. Background technique [0002] Fracture repair is the process of rejoining and realigning the ends of broken bones. When it is necessary to restore the normal position and function of the broken bone, fracture repair is required. Throughout the fracture healing phase, the bone must be held firmly in the correct position and supported until it is strong enough to support the weight. If the fracture is not properly repaired, the dislocation of the bones may occur, causing possible physical dysfunction of the bones or joints in that area of ​​the body. [0003] Until the last century, doctors relied on molds and splints to support bones from outside the body (external fixation). However, the development of aseptic surgery has...

AI Technical Summary

Problems solved by technology

Conventional bone cement injection devices have difficulty adjusting or controlling bone cement injection volume or injection rate in real time in response to cancellous bone volume and density conditions encountered inside a fractured bone

Traditional bone cements can also cause complications, including leakage of bone cement into the outer area of ​​the fractured bone site, which can lead to soft tissue damage as well as nerve root pain and constriction
