<p>The present patent comprises a needle holder (1) including two articulated shafts (2 and 3), of scissors type, with a leaf spring (4) therebetween, the function of which is to guarantee 45° opening between an anterior fastening segment (2A) and an anterior engagement segment (3A), for a straight (5) or curved (5A) needle, the respective shafts being contiguously connected via an articulation drum (6) formed by rings (6A and 6B) that are coupled by a central rod with diametrically projecting locking device (7) inserted in a symmetrical axial hole (8) with internal depression (9). The anterior fastening segment has a through-hole (10) of square section, which fastens the straight needle through the lower section thereof, which is also of square section, and which likewise fastens the curved needle in two different positions. Said fastening is achieved by means of compressing a split oblong ring (11) (locking pin), screwed to one of the ends, which holds the straight or curved needle via compression of the sections thereof formed by a transverse cut (12). The anterior engagement segment further comprises an engagement slot (13) for engagement with the re-entrant part (14) of the straight or curved needle.</p> |
