A wide variety of disposable and reusable trocars have been designed and marketed for use in laparoscopic surgery. The performance of these instruments varies considerably. Disposable trocars usually contain valve designs which allow the easy passage of instrumentation and safety mechanisms which reduce the likelihood of visceral injury from the trocar point. Whilst most reusable trocars have not provided safety mechanisms, and have been less user-friendly, newer designs are beginning to bridge the gap. The choice of a trocar for laparoscopic surgery will depend on each surgeon's perception of the advantages and disadvantages of competing instrumentation, which may need to be balanced against the budgetary requirements of their practice location.
已经设计并销售了各种各样的一次性和可重复使用的套管针用于腹腔镜手术。这些器械的性能差异很大。一次性套管针通常包含允许器械轻松通过的阀门设计以及减少套管针尖端造成内脏损伤可能性的安全机制。虽然大多数可重复使用的套管针没有提供安全机制，而且对用户不太友好，但新的设计正开始缩小差距。腹腔镜手术中套管针的选择将取决于每位外科医生对相互竞争器械优缺点的看法，这可能需要根据他们所在医疗机构的预算要求进行权衡。
