Which statement correctly describes tungsten carbide tipped needle holders?

• A. They are cheaper than smooth tips and wear quickly.
• B. They are identical in performance to smooth tips.
• C. They are weaker than toothed tips and damage sutures easily.
• D. They last longer and cause less damage to sutures than toothed tips.

Answer: (D)

Durability and suture safety of needle holders are shaped by tip material. Tungsten carbide tips are extremely hard and wear-resistant, so they maintain their alignment and grip quality far longer than ordinary stainless-steel tips. This means less frequent replacement and steadier performance during repeated use. At the same time, their gripping surfaces tend to be smoother and more controlled than toothed tips, which can crush or nick delicate sutures with their teeth. That combination—lasting wear resistance and gentler, more precise handling of sutures—explains why tungsten carbide tipped needle holders last longer and cause less damage to sutures than toothed tips.
