Abstract: In a bipolar pincette having two pincette arms (12.sub.a) which are connected at one end by a holding means and which are electrically insulated from each other, the holding means has two interconnected channel-like profile portions (24.sub.a) each of which is provided with two insertion slots or the like guide paths for a respective blade-like region or a gripping blade (20) of one of the pincette arms (12.sub.a) and bears against a longitudinal edge of the pincette arm or gripping blade. The channel-like profile portions (24.sub.a) are formed from ceramic material or metallic material; the latter is provided with an electrically insulating coating layer.

Abstract: A surgical instrument, in particular microsurgical scissors or cutters or tweezers or forceps, with a gripping portion and at least one gripping surface which extends over at least a section of the gripping portion and which affords enhanced friction in comparison with the adjacent sections of the instrument, is improved in that the gripping surface is in the form of a roughening with small, juxtaposed raised portions and depressed portions of different dimensioning and with an arrangement which is irregular in respect of dimensioning.

Abstract: A microsurgical pincette consists of two metallic arm members and a metallic connection member, rigidly fixing the two arm members one to each other at an end region of the arm members. To ensure an electric insulation between the two arm members, a part of their length, including said end region, is provided with an oxide protection coating, preferably consisting of aluminium oxide, applied by plasma coating technique.
