[origin: WO9406681A2] An automatic retractable safety penetrating instrument for introduction of sleeves, such as portal sleeves, cannulas and catheters, into anatomical cavities by means of penetrating members, such as solid tip trocars, other solid configuration obturators and cannulated penetrating members, such as needles, include locking and releasing mechanisms for automatic retraction ot the penetrating member into the sleeve upon the sleeve entering the anatomical cavity. Various locking and releasing mechanisms are utilized for disposition in the penetrating member hub, in the shaft of the penetrating member or partially in the shaft and the hub, and the penetrating member can be made of telescoping distal and shaft sections to minimize the length of the penetrating member hub.
