The Protractor is a self-retaining ring retractor used mainly for minilaparotomies in adults. We report our positive results of using this retractor in pediatric surgery. We performed surgery with the aid of the Protractor in 57 pediatric patients aged from 1 day old to 16 years old. The Protractor allowed a wide operative view and did not cause any major complications. It was especially useful for Kasai's portoenterostomies and ureteroneocystostomy (Cohen's repair). In neonatal surgery, the Protractor not only provided a wide operative view, but also prevented the washing fluid from overflowing onto the covering sheet. In appendectomy, the Protractor protected the surgical wound from contaminated ascites and the appendix. The Protractor is a very useful tool for assisting with various abdominal operations in infants and children.
量角器是一种主要用于成人小型剖腹手术的自固定环形牵开器。我们报告了在小儿外科手术中使用这种牵开器的积极结果。我们在57例年龄从1天至16岁的儿科患者中借助量角器进行了手术。量角器可提供广阔的手术视野，且未引起任何重大并发症。它对Kasai肝门空肠吻合术和输尿管膀胱再植术（科恩修复术）特别有用。在新生儿手术中，量角器不仅提供了广阔的手术视野，还防止冲洗液溢出到覆盖单上。在阑尾切除术中，量角器可保护手术伤口免受污染腹水和阑尾的影响。量角器是辅助婴幼儿各种腹部手术的非常有用的工具。
