Patent

CA 2050117

A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue. The distal end of the shield is hemispheric in profile and contains a slot which conforms to the geometry of the cutting tig. Instead of using a discrete shield component the shielding function may be provided by spring-loading the trocar tube itself to spring forward and shield the obturator tip after the tip penetrates tissue. Alternately a safety mechanism insures the tip is covered by the shield after the tip penetrates tissue.
