medical instrument with kunststoffgriffen with torsionssicherung

摘要

medical instrument (30, 65) by a gap (30) or a nadelhalters (65) with a first (31, 66) and a second lever (32, 64), which in its distal end (33, 34,68 and 69) each werkzeugteil (35, 36, 70, 71) in which each with a proximal griffteil (40, 41, 75, 76) is connected.with a metallic material existing parts (35, 36, 70, 71) for pressing the griffteile (40, 41, 75, 76) for a lagerachse (37,72) from an open position against the torque of at least one ru00fcckstellelementes (44, 45, 79, 80) in a closed "position" revolving (arrows 2526) and the respective griffteil (40, 41, 75, 76), with the griffteil (40, 41, 75, 76) fixed coupled verbindungsabschnitt (38, 39, 73, 74) are characterised bythat either one or both of griffteile (40, 41, 75, 76) from a form plastic.and are fixed with the corresponding verbindungsabschnitt (38, 39, 73, 74) of the werkzeugteils (35, 36, 70, 71) are connected, and in the proximal end (42, 43, 77,78), the griffteile (40, 41, 75, 76) between the griffteilen (40, 41, 75, 76) guiding elements (55, 58, 56, 57, 90, 91, 92, 93),what in the betu00e4tigungsbewegung the griffteile (40, 41, 75, 76) from their position in the "closed" position so adjustable interlock,a tordierende verwindung and / or a side slip of the plastic existing griffteils (40, 41, 75, 76) or plastic existing griffteile (40, 41, 50,76) is avoided.
