INTRAMEDULLARY FIXING DEVICE THAT CAN EFFECTIVELY PROMOTE FRACTURE HEALING

WIPO Patent Application WO/2017/080131

A1

Disclosed is an intramedullary fixing device that can promote fracture healing, characterized in that: the intramedullary fixing device comprises a plurality of short cylinders (1) and a plurality of connection structures, wherein the plurality of short cylinders (1) are arranged in a staggered manner, the plurality of connection structures are respectively connected to the two adjacent short cylinders (1), and each connection structure has a plurality of spaces where bone trabeculae can grow. The intramedullary fixing device that can promote fracture healing is made by the interconnection of the plurality of short cylinders (1) and a plurality of upright columns (2), wherein the short cylinders (1) can provide enough support strength, and the connection structures have the plurality of spaces where bone trabeculae can grow. The intramedullary fixing device can allow the bone trabeculae to grow along and into the spaces of the connection structures, so that the intramedullary and extramedullary bone calluses can grow at the same time, thereby shortening the time of fracture healing, recovering the physiological and mechanical properties, and reducing complications with fractures and the operation.
