摘要： To enable puncture of a body wall with a greater degree of sensitivity with a surgical obturator for puncturing the body wall having a knife, the cutting edge of which extends outwards from a tip of the obturator in the direction of various sides and backwards in relation to the tip, and which is orientated throughout its entire length parallel to the puncturing direction, so that the cutting edge points in the puncturing direction, it is proposed that the cutting edge be of helical line-shaped configuration.

摘要： A surgical obturator is provided which has a tubular housing, a blade carrier displaceable in the tubular housing in a longitudinal direction between an advanced cutting position and a retracted protected position. A blade with a cutting edge is held on the blade carrier. A protective cap engages over the blade and is displaceable in the tubular housing in the longitudinal direction between an advanced rest position in which the blade is completely covered in its protected position and a retracted work position. The protective cap has a slit through which the cutting edge passes. In a work position of the protective cap, the blade projects through the slit. A retracting device is arranged in the tubular housing for displacing the blade from the cutting position to the protected position. The retracting device is activatable by displacement of the protective cap from the work position to the rest position.

摘要： In a surgical obturator with a tubular housing, with a blade carrier displaceable in the tubular housing in the longitudinal direction between an advanced cutting position and a retracted protected position, a blade with a cutting edge being held on the blade carrier, the cutting edge being guided in a correspondingly extending guide of the tubular housing, with a protective cap engaging over the blade and being displaceable in the tubular housing in the longitudinal direction between an advanced rest position in which the blade is completely covered in its protected position and a retracted work position, the protective cap having a slit through which the cutting edge of the blade passes and, in the work position of the protective cap, projects over the latter, and with a retracting device arranged in the tubular housing and displacing the blade from the cutting position to the protected position, the retracting device being activatable by displacement of the protective cap from the work position to the rest position, in order to reduce the size of the retracting device, it is proposed that the retracting device comprise a switching element which fixes the blade in the cutting position and, upon activation, releases the blade for displacement to the rest position, the switching element being mounted in the tubular housing so as to be freely rotatable about the longitudinal axis of the tubular housing and immovable in the longitudinal direction, and the switching element being rotatable, upon displacement of the blade carrier and/or the protective cap in the longitudinal direction of the tubular housing, by means of a cam guide which is operative between the switching element, on the one hand, and the blade carrier and/or the protective cap, on the other hand.
