Surgical trocar

Image Number 4 for United States Patent #5342382.

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 slides within cutting tip. The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue. In other embodiments, positive mechanical means effect shielding. Alternately, the obturator tip is retractable into the cannula or shield, by use of mechanical means such as a spring mechanism.
