Abstract
A trocar sleeve comprises a flexible hollow shaft comprising a distal end and a proximal end, and a handling head that is formed at the proximal end of the hollow shaft. The trocar sleeve is manufactured from an elastomer material. The hollow shaft comprises an inner contour that is adapted to an outer contour of a trocar mandrel in such a way that the trocar sleeve and the trocar mandrel are arranged to be coupled to one another while generating a defined preload to stabilize the trocar sleeve. A trocar system comprises a trocar sleeve and a trocar mandrel that is arranged to be inserted in the trocar sleeve, while generating a defined preloading in the trocar sleeve. A method of manufacturing a trocar sleeve involves integrally forming a hollow shaft and a handling head in a common mold by molding.
