    Abstract: 一种不损伤毛囊的毛发移植方法及移植系统,毛发移植方法包括毛囊选取(A)、毛发提拔(B)、毛囊切取(C)、毛囊装针(D)、毛囊种植(E),毛发移植系统包括毛囊获取装置、毛囊种植装置。毛囊获取装置包括截取器、毛发拔,截取器内设中空毛囊护筒(101),毛囊护筒(101)外套设筒状切割刃(102),切割刃(102)外设置护盖(3)。毛发移植方法采取提拔待取毛囊(7)上的毛发(6)对凸起皮肤切割而非插入式获取毛囊,毛发毛囊(7)在毛发拔持续牵引下拖入毛囊护筒(101)内,内筒保护、中筒切割、外护盖(3)固定皮肤,从而避免毛囊锐性损伤。毛囊种植时顺装进入毛囊筒(1401)内,避免修剪和针尖损伤毛囊,毛囊(7)的装填及位移过程都在套筒内完成,避免了毛囊与受区组织的摩擦进而减少了毛囊的挫伤和挤压伤,针芯(1201)抵压毛囊(7)时退出针管不会带出毛囊,从而实现毛囊自提取到种植全过程毛囊损伤最小化,种植成活率大大提高。

    Abstract: A digital control method for inverters and frequency conversion comprises steps of: firstly, taking logic switch "0" or "1" as off or on status of each power switch tube and arranging "0" and "1" sequentially to form digit code for all the power switch tubes in the circuit; secondly, calculating the duration of each status on the basis of the defined modulation waveform and the period decided by the frequency of the output AC voltage; finally, outputting orderly respective digit code sequence and duration for all the power switch tubes in the circuit in accordance with the data obtained by preprocessing to form the modulation waveform of each switch; representing the digit code with hex system.
