目的研制符合面部的恒压恒量微创颗粒脂肪注射移植装置,并评估其临床应用价值.方法针对面部脂肪移植小体积、高推力和高精度的要求,采用控制器和电机一体化手持式设计,使脂肪注射移植装置体积更小、重量更轻,以适应面部精细移植的需要.2013年11月至2015年3月,选取50例面部自体脂肪移植患者,同一患者右侧面部采用该装置进行脂肪移植,左侧面部采用注射器手推方式作为对照,同期移植脂肪,并由患者、术者及1名与本研究无关的第三者对临床效果进行评价,内容包括术中疼痛程度、推注难易、术后肿胀和青紫程度、并发症及整体满意度等,疼痛强度评估采用数字分级法(NRS),治疗效果采用李克特(Likert)5分评分法.分别采用x2检验、秩和检验和方差分析进行统计学分析.结果该装置体积小巧,操作轻便,推注速度为7.2 mm/s,脂肪注射量可以精确控制到0.04 ml/s,脂肪移植量达到0.005 6 ml/mm,可实现高精度注射.50例患者面部右侧治疗效果优良百分比为90％(45/50),左侧为78％ (39/50),右侧明显高于左侧(Z=-4.285,P＜0.01);注射局部硬结:右侧为0,左侧7例(x2=6.57,P＜0.05);淤斑:右侧21例,左侧45例(x2=5.37,P＜0.05);疼痛程度:右侧为(3.7±1.1)分,低于左侧的(5.2±0.7)分(F=17.405,P＜0.01).结论面部恒压恒量微创颗粒脂肪注射移植装置,外观设计符合人体工程学要求,操作简便,注射移植精确度高,并发症少,患者痛苦小,满意度高.

Objective To develop and evaluate the application of the facial minimally invasive fat granules injection device with controlled pressure and quantity.Methods Due to the requirement of facial fat grafting(small volume, precision, high pressure), we developed the integrated device with handheld controller and motor.From Nov.2013 to Mar.2015, 50 cases who underwent facial fat transplantation were selected to receive facial fat grafting with the device on the right side and with conventional syringe on the left side as control.The clinical effect was assessed by patients, surgeon and one from the third party.The intraoperative pain, injection difficulty, postoperative swelling and bruising, complications and overall satisfactory were recorded.Pain intensity was assessed using digital classification method (NRS).Therapeutic effect was evaluated using Likert 5 points scoring method.Chi-square test, Wilcoxon test and one-way ANOVA were used for statistical analysis.Results The device has the advantages of minimal designed and easily handling.The injection speed is 7.2 mm/s with the fat injection volume as precise as 0.04 ml/s(0.0056 ml/mm).Among the 50 cases, the excellent and good effect were achieved in 90％ (45/50) on the right face, and 78％ (39/50) on the left face (Z =-4.285,P ＜ 0.01).Local nodes happened in 7 cases on left face, while none on the right face(x2 =6.57,P ＜0.05).Petechiae occurred in 21 cases on right face and 45 cases on left face(x2 =5.37,P＜0.05).Pain was assessed as 3.7 ± 1.1 points on the right sides, and 5.2 ± 0.7 points on the left sides(F =17.405, P ＜ 0.01).Conclusions The facial minimally invasive fat granules injection device with controlled pressure and quantity has the advantages of easily handling, precisely controlled quantity with better effect, less pain and complication.
