Preparation device of bone cement fixation in total knee arthroplasty

摘要

A useful model refers to the field of medicine, especially orthopedics, It can also be used in knee arthroplasty to prepare tibia and femur saw blade for cement fixation.;A useful model for the preparation of bone cement fixation in knee arthroplasty is proposed. The result is that the quality of cement is improved Fixed,Simplify the execution of the hole,Forming the best size hole,Preservation of bone tissue,Extend the functional time of the implant.;The technical achievements areThe bone chip cement fixation preparation device for knee joint replacement comprises the following elements: a handle,Impact pad and workpiece with thorn,Its characteristics are as followsThe working part is a semicircular metal plate,There are sharp spines on the surface of the workpiece, which are like pyramids,There is a passage between them.
