Abstract
A trocar system is provided for use in obtaining access into a body cavity for laparoscopic/endoscopic procedures. The trocar system includes a protective housing releasably secured to a trocar housing. An obturator shaft is slidably mounted within the housings and has a stylet at an end thereof terminating at a sharp tip. The obturator shaft is movable in a direction of movement between a retracted position, wherein the sharp tip is retracted into the protective housing, and an extended position, wherein the sharp tip extends out of the protective housing. The trocar system also includes a latching and release mechanism provided within the trocar housing for latching the shaft in its extended position and for releasing the shaft to allow retraction thereof to its retracted position. This latching and release mechanism includes a slide plate movable between first and second positions for permitting movement of the obturator shaft between its retracted and extended positions.
