ABSTRACT:
In a surgical obturator for piercing a body wall, comprising a tubular housing that at one end forms an introduction tip with a continuously decreasing diameter, and comprising a blade projecting from the introduction tip for making an incision in the body wall, in order to reduce the risk of injury during piercing of the body wall it is proposed that the introduction tip comprises a central protective cap, which is displaceable in longitudinal direction relative to the introduction tip between an advanced inoperative position and a retracted working position, that the blade in the housing is displaceable in longitudinal direction between an advanced cutting position and a retracted protected position, that disposed in the housing is a retraction device that displaces the blade from the cutting position into the protected position, and that the retraction device may be activated by a displacement of the protective cap from the working position into the inoperative position.
