Micro Scissors TC Straight (18cm)

The Micro Scissors TC Straight (18cm) measures 18 cm in total length with a cross-sectional handle diameter of approximately 1.3 cm, built from AISI 420 stainless steel at a Rockwell hardness of 48–58. The straight blade configuration carries tungsten carbide inserts along both cutting edges, marked by gold-plated rings at the base of the spring handle — a standard TC identification feature across the Castroviejo instrument range. TC inserts extend cutting edge durability up to thirty times beyond standard stainless blades, maintaining a consistent shear line through repeated suture and tissue cuts. The double-ring spring handle with a finely knurled grip section returns the blades to an open position automatically after each activation, allowing continuous single-handed use without hand reset.

Unlike their curved counterparts, T.C. Micro Scissors in straight configuration deliver direct linear cutting strokes along flat tissue planes and suture lines. The straight blade alignment gives the operator an unobstructed sightline along the full cutting path, which is critical when working under magnification loupes or a surgical microscope. Fine, pointed tips allow accurate placement at suture knots or tissue margins without disturbing the surrounding field. The instrument is fully autoclavable and maintains dimensional integrity through repeated sterilization cycles.

Periodontists and oral surgeons use Micro Scissors TC Straight (18cm) for suture removal, trimming collagen membrane edges, cutting suture material flush to knots, and incising gingival tissue during flap procedures on anterior teeth and premolars. Straight micro scissors of this pattern are also standard instruments during guided tissue regeneration and free gingival graft procedures where straight-line cuts are needed along defined tissue borders.

Leader Surgical manufactures this instrument with verified TC insert bonding and blade alignment, supporting consistent cutting performance across every surgical session.

What does “Straight” signify in this model?
The straight blade configuration is typically used for general cutting tasks, linear tissue dissection, and trimming sutures in surgical and laboratory settings.
