What type of surgical instrument has a groove or hook to slide under sutures?

1. Puncture scissors

2. Suture scissors

3. Hemostatic forceps

4. Needle holders

The correct answer is: Suture scissors

The instrument that features a groove or hook specifically designed to slide under sutures is indeed suture scissors. Suture scissors are specially designed with a pointed end that allows for precise and careful cutting of sutures without damaging the surrounding tissue. The unique groove or hook assists in easily catching the suture material, enabling the user to lift and cut it effectively, which is particularly important during surgical procedures or when removing stitches after healing. In contrast, puncture scissors are designed for cutting tissue and materials but do not have the specific feature for catching sutures. Hemostatic forceps are used to clamp blood vessels or tissues to control bleeding, and needle holders are used to grasp and manipulate suturing needles during surgical procedures. While all these instruments have important roles in a surgical setting, suture scissors are distinctively engineered for the task of cutting sutures.
