Medical instruments used in minimally invasive surgery are suitable for small, thin and narrow spaces, so medical tools must be made of high-strength steel materials to meet the operation requirements including cutting, cutting, setback, torsion and cutting, and avoid the tools from being broken and remaining in the human body.
Tools for minimally invasive surgery must meet the following requirements:
1High rigidity and can cut, cut, clamp and twist;
2Heating by current and oscillating by ultrasonic wave;
3In vitro operation, the tool must be able to pass the diameter only5MMThe aperture of;
4Have complex features to provide necessary functionality, such as sampling pliers, micro scissors and other tools;
5Materials of tools shall be harmless to human body.
At present, the design and application of metal injection molding parts in medical device industry is not wide enough, for several reasons:
01.Do a good job in technical exchange and promotion of metal injection molding
02.Successful R&D intensity is greater than1000MPa, salt spray test meets1000hIs suitable for the field of medical devices
