Mechanical Property Comparison Analysis of Two Kinds of Shape Memory Alloy Patella Claws Based on Finite Element Method
Memory alloy' is a new material that is widely applied for medical equipment. The successful orthopedic repair of severe transverse patella fractures is being advanced through the use of the 'memory alloy patella claw'. We have refined the basic design of this device, by comparing the mechanical properties of patella claws, before and following after refinement of the claw design using finite element model that are simulated by ABAQUS software. When the same load was imposed on each patella claws, under the same boundary conditions, the stress-strain value of anti-shearing force patella claw was smaller. These data indicate that the finite element model demonstrates an efficient way of designing this orthopedic device to produce effective anti-shearing force patella claws, which is of potentially significant benefit to the treatment of patella fractures.
