The learning of microsurgical techniques and the maintenance of microsurgical skills have been traditionally based on the use of living animals, mainly laboratory rats. This method although extremely valuable can be economically demanding both for the surgeon and the sponsoring institution; it also requires special training facilities that may not always be available or accessible. Furthermore ethical concerns can limit the use of living animals for training purposes. Alternative training methods, such as inert tubes and gloves have not gained popularity among surgeons since they do not offer an experience similar to that of a clinical situation. Non-living animal models include the use of chicken thighs and wings; they offer a practice experience that resembles a clinical situation to a considerable extent. This type of training is relatively cheap and easily available. The microscope and instruments required can be acquired over the internet, and the chicken pieces can be bought at the local supermarket. This approach allows a motivated trainee to rehearse different types of surgical techniques several times at a reasonable expense, helping to develop or maintain his surgical expertise if more complex facilities are not available. On the current manuscript we describe how to setup a small practice station, how to dissect the specimens, and how to practice both with the chicken thighs and with the chicken wings in a progressive fashion. This approach takes advantage on the versatility of the chicken thigh model and the small size of the chicken wing Brachial artery.
传统上，显微外科技术的学习和显微外科技能的维持基于使用活体动物，主要是实验室大鼠。这种方法虽然极其有价值，但对外科医生和赞助机构来说在经济上要求都很高；它还需要特殊的训练设施，而这些设施可能并不总是可用或可及的。此外，伦理问题可能会限制将活体动物用于训练目的。替代训练方法，如惰性管和手套，在外科医生中并未受到欢迎，因为它们无法提供与临床情况类似的体验。非活体动物模型包括使用鸡大腿和鸡翅；它们提供了在很大程度上类似于临床情况的实践体验。这种类型的训练相对便宜且容易获得。所需的显微镜和器械可以通过互联网购买，鸡块可以在当地超市买到。这种方法使有积极性的受训者能够以合理的费用多次演练不同类型的外科技术，如果没有更复杂的设施，有助于培养或维持其外科专业技能。在当前的手稿中，我们描述了如何设置一个小型练习站，如何解剖标本，以及如何以渐进的方式使用鸡大腿和鸡翅进行练习。这种方法利用了鸡大腿模型的多功能性和鸡翅肱动脉的小尺寸。
