Use of a mechanical arm to hold the laparoscopic camera has many advantages. FreeHand (FreeHand Ltd, Guildford, United Kingdom) is a robotic camera holder which uses head movement and infrared technology. This trial assessed the usefulness of FreeHand in laparoscopic appendicectomy. This was a single center prospective cohort study on patients undergoing emergency laparoscopic appendicectomy using FreeHand. Patient demographics, operative details, conversion to human camera holder and surgeon discomfort were recorded. Utilization of assistant time while not assisting was also recorded. Twenty-two participants were included, with a mean age of 32 years and a mean BMI of 25.3. The mean set up time was nine minutes. There were five conversions to a manual camera holder (22.7%). There were 22 lens cleaning episodes with nine (40.9%) not requiring any lens cleaning and six (27.3%) requiring one clean. There were no peri-operative complications. Most surgeons reported minimal or no discomfort. Assistant's time was used for ward work (57%), clerking patients (36%) and for a break (7%). FreeHand can be safely used in laparoscopic appendicectomy. It provides a stable image, puts the surgeon in control of the surgical field, causes minimal user discomfort, and frees up personnel.
使用机械臂握持腹腔镜摄像头有诸多优点。FreeHand（英国吉尔福德的FreeHand有限公司）是一种利用头部运动和红外技术的机器人摄像头固定器。本试验评估了FreeHand在腹腔镜阑尾切除术中的实用性。这是一项针对使用FreeHand进行急诊腹腔镜阑尾切除术患者的单中心前瞻性队列研究。记录了患者人口统计学资料、手术细节、转换为人工摄像头固定器的情况以及外科医生的不适感。还记录了助手在不提供协助时的时间利用情况。纳入了22名参与者，平均年龄为32岁，平均体重指数为25.3。平均设置时间为9分钟。有5例转换为手动摄像头固定器（22.7%）。有22次镜头清洁情况，其中9次（40.9%）不需要任何镜头清洁，6次（27.3%）需要一次清洁。没有围手术期并发症。大多数外科医生报告极少或没有不适感。助手的时间用于病房工作（57%）、接待患者（36%）和休息（7%）。FreeHand可安全用于腹腔镜阑尾切除术。它能提供稳定的图像，使外科医生能够掌控手术视野，引起的使用者不适感最小，并能腾出人员。
