Objective To explore the improvement effect of diamond-like carbon(DLC)on the cutting performance of medical shavers.Methods With the use of the medical shavers treated with DLC coating in the experimental group and medical shavers treated with passivation in the control group,comparative experiments were conducted on isolated animal tissues(fresh pig lean meat).The cutting depth,wound cleanliness,and degree of tissue thermal damage were recorded and compared between two different working modes.Results With the working modes of unidirectional rotation(3000,4500,6000 r/min)and reciprocating rotation(3000 r/min,0.5 Hz,4500 r/min,2.5 Hz,6000 r/min,4 Hz),the cutting depth and wound cleanliness of the experimental group were higher than those of the control group,and the differences were statistically significant(P<0.05).No tissue thermal damage was observed in both groups with the two working modes.Conclusion The application of DLC coating on medical planers can increase cutting efficiency,enhance wound cleanliness,and significantly improve cutting performance.
