Laparoscopic trainers have gained recognition for improving laparoscopic surgery skills and preparing for operations on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for young surgeons in small medical centers. The solution might be for them to construct a device by themselves.
To make a relatively cheap and easy to construct laparoscopic trainer for residents who wish to develop their skills at home.
TWO LAPAROSCOPIC SIMULATORS WERE DESIGNED AND CONSTRUCTED: 1) a box model with an optical system based on two parallel mirrors, 2) a box model with an HD webcam, a light source consisting of LED diodes placed on a camera casing, and a modeling servo between the webcam and aluminum pipe to allow electronic adjustment of the optical axis.
The two self-constructed simulators were found to be effective training devices, the total cost of parts for each not exceeding $100. Advice is also given for future constructors.
Home made trainers are accessible to any personal budget and can be constructed with a minimum of practical skill. They allow more frequent practice at home, outside the venue and hours of surgical departments. What is more, home made trainers have been shown to be comparable to commercial trainers in facilitating the acquisition of basic laparoscopic skills.
腹腔镜训练器因能提高腹腔镜手术技能并为人体手术做准备而受到认可。不幸的是，由于价格高昂，商业模拟器很难获得，尤其是对于小型医疗中心的年轻外科医生来说。解决办法可能是他们自己制作一个设备。
为希望在家中提高技能的住院医生制作一个相对便宜且易于构建的腹腔镜训练器。
设计并构建了两种腹腔镜模拟器：1）一种基于两个平行镜的带有光学系统的箱式模型；2）一种带有高清网络摄像头、由放置在摄像头外壳上的发光二极管组成的光源以及位于网络摄像头和铝管之间用于电子调节光轴的建模伺服装置的箱式模型。
发现这两种自制模拟器是有效的训练设备，每个的零件总成本不超过100美元。还为未来的制作者提供了建议。
自制训练器在任何个人预算范围内都可获得，并且只需最少的实践技能就能构建。它们允许在家庭、手术科室以外的场所和时间进行更频繁的练习。此外，事实证明自制训练器在促进基本腹腔镜技能的掌握方面与商业训练器相当。
