Abstract

A trocar is described. The trocar is formed of a biocompatible material, such as but not limited to stainless steel. Accordingly, the trocar is reusable for a relatively large number of surgical procedures assuming conventional sterilization techniques are employed after each surgical procedure. Additionally, the trocar is provided with an angled blade design formed on a distal portion of the trocar shaft. More specifically, the blade design includes a first portion extending substantially co-planar to a proximal portion of the tip portion of the trocar shaft and a second portion extending angularly inwardly towards a distal portion of the tip portion of the trocar shaft.
