摘要 目的:探讨基于光学追踪系统和力传感技术的吸脂针运动记录系统在吸脂术中对吸脂针运动数据的检测效果,并分析检测数据与吸脂效率的关系。方法:选取中国医学科学院整形外科医院2019年1月至2019年9月符合入选标准的脂肪抽吸手术患者。分别由A、B 2位术者抽吸患者吸脂区域的左侧和右侧,通过基于光学追踪系统和力传感技术的吸脂操作记录系统,采集术者250~400 s的操作轨迹数据和力数据,测量试验时间内吸出的脂肪量,分析比较2位术者吸脂针运动的幅度、频率、前进阻力,计算并对比吸脂效率。数据采用配对t检验和符号秩和检验进行分析。结果:共入组18例患者,均为女性,年龄23~49岁,平均37岁。吸脂部位分别为腹部、大腿、腰部。术者A的吸脂针运动幅度和前进阻力分别为(11.43±1.23)cm和(9.35±2.24)N,高于术者B的(10.00±2.33)cm和(8.20±3.05)N,差异均具有统计学意义(t=2.780、P=0.013,t=2.328、P=0.033)。术者A吸脂针运动的频率为(2.14±0.19)Hz,术者B为(2.19±0.55)Hz,二者比较差异无统计学意义(t=-0.366、P=0.719)。术者A的吸脂效率为(19.20±9.36)ml/min,术者B为(15.27±8.05)ml/min,A比B高3.93 ml/min,差异具有统计学意义(t=3.736、P=0.002)。结论:基于光学追踪和力传感技术的吸脂针运动记录系统,可以很好地记录和分析吸脂术术者的操作轨迹和阻力,并发现吸脂针的运动幅度和前进阻力较大时,吸脂效率更高。 Objective This study aims to discuss the detection effect of a novel liposuction cannula movement recording system based on optical tracking technique and force sensor during liposuction and analyze the relationship between recorded data and liposuction efficiency.Methods The patients who met inclusion criteria underwent liposuction from January 2019 to September 2019 were enrolled in this study and operated on by two surgeons with extensive liposuction experience.During a given procedure,one surgeon performed liposuction on one side of the targeted liposuction area,another surgeon performed liposuction on the contralateral side.The trajectory and force of liposuction cannula were recorded for approximately 300 seconds,and the volume of upper layer fat in liposuction aspirate was measured during experiment.The average amplitude,average frequency,and average forward resistance of the liposuction needle movement of the two surgeons were compared,and the liposuction efficiency was calculated and compared.The data were analyzed by paired t-test and signed rank sum test.Results Eighteen patients were enrolled.All patients were females at 23-49 years old,with the mean age of 37 years old.Liposuction was performed in the abdomen,thighs,and waist.The movement amplitude and forward resistance of the liposuction cannula of surgeon A were(11.43±1.23)cm and(9.35±2.24)N,which were higher than those of surgeon B(10.00±2.33)cm and(8.20±3.05)N,and the differences were significant(t=2.780,P=0.013;t=2.328,P=0.033).The frequency of liposuction cannula movement of surgeon A was(2.14±0.19)Hz,and that of surgeon B was(2.19±0.55)Hz.There was no significant difference between the two surgeons(t=-0.366,P=0.719).The liposuction efficiency of operator A was(19.20±9.36)ml/min,and the efficiency of operator B was(15.27±8.05)ml/min.A was 3.93 ml/min higher than B.The difference was statistically significant(t=3.736,P=0.002).Conclusions The liposuction cannula movement recording system based on optical tracking and force sensing technology established in this study can record and analyze the operation trajectory and resistance of the liposuction cannula.When the movement amplitude and forward resistance of the cannula are larger,the liposuction efficiency is higher.
