Abstract

The invention relates to a frictional wear testing device of an orthopaedic implantation instrument. The frictional wear testing device comprises a machine-table frame, a cam, a balance-weight collecting module and a movement module. The cam is installed on a motor of the machine-table frame, one end of the movement module is connected with the cam, and the balance-weight collecting module and the movement module are fixed on a bottom plate of the machine-table frame through a screw; a balance weight of the balance-weight collecting module is arranged over a sample box of the movement module. The motor of the machine-table frame drives the cam to rotate, rotation of the cam is converted into left-right reciprocating rectilinear movement of a long movement plate in the movement module, and a test piece is subjected to a frictional wear test. By means of the frictional wear testing device, the movement condition of the human body can be simulated through reciprocating movement; the frictional wear characteristic of the orthopaedic implantation instrument can be tested under the different loading conditions; manufacturing cost and maintaining cost are low, operation is convenient, and application and popularization are easy.

Description

technical field [0001] The invention relates to a friction and wear testing platform, in particular to a friction and wear testing device for orthopedic implantation instruments. Background technique [0002] Orthopedic implanted devices are an important supporting technology in orthopedics. Orthopedic implanted devices are used to solve diseased or damaged orthopedic problems, which can help patients resume normal movement and improve their quality of life. It is of great significance to human health engineering and has a huge potential market value. [0003] Friction and wear performance is an important parameter index in orthopedic implant technology, which directly affects the reliability and long-term stability of orthopedic implant devices. Both the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM) have formulated relevant in vitro testing standards for the friction and wear properties of orthopedic implant ...
