Abstract

An apparatus is disclosed for automatically locking an obturator housing to a cannula housing of a trocar assembly when the obturator is advanced to a predetermined distal position. Two latch devices are mounted for pivotal movement within the obturator housing with each having at least one latch positioned at one end thereof. The pivoting latch devices are automatically pivoted into locked engagement with partial apertures or indentations in the cannula housing such that the obturator housing is secured to the cannula housing. Biasing springs are provided to automatically pivot the pivoting latch devices out of engagement with the cannula housing when the obturator is withdrawn to its proximal position.
