| titleOfInvention |
Diamantine surface coating for surgical instrument - is formed by plasma deposition from mixed hydrogen and gaseous hydrocarbon |
| abstract |
The pointed or cutting work-surface (1) of an instrument for piercing or cutting a patients body is coated to a depth of 1-20nm with a layer (2) of carbon at least partly with diamond crystal structure. The layer is applied by a plasma vapour deposition process carried out in an atmos. of H2 and hydrocarbon gases, esp. methane, ethane or propane, with a very wide range of possible proportions. The plasma is formed with a microwave frequency of 1-10 GHz and applied to a substrate at 300-1300 deg.C. ADVANTAGE - Instrument has min. friction, with no effect on blood coagulation, and is stable w.r.t. body fluids. |
