ABSTRACT:
The invention relates to a sealing cap for guide tubes or reducing sleeves for inserting surgical instruments containing an all-round skirt extending down from the end wall of the sealing cap. The internal diameter corresponds to the external diameter of the tubular headpiece of the guide tube or reducing sleeve or is somewhat smaller. Below the end wall is provided a circular groove for receiving an all-round circular flange on the headpiece of the guide tube or reducing sleeve. In the center of the end wall is provided a circular insertion opening for the surgical instrument to be inserted in the guide tube or reducing sleeve. The sealing cap is made from a flexible, natural or synthetic rubber-like material, characterized in that on the lower edge of the skirt is shaped a gripping tongue whose outer boundary edges pass tangentially from two virtually diametrically facing areas of the skirt and pass into one another in a rounded portion on the outer gripping tongue end. On the gripping tongue top and/or bottom an arcuate bead is shaped in the rounded region of the outer gripping tongue end. The circular groove provided below the end wall is spaced from the underside of the end wall.
