What type of instrument is a suture scissor?

A suture scissor is specifically designed as a surgical instrument for cutting sutures. This tool features a sharp blade that can efficiently cut through the material used for stitching, making it an essential device in various surgical and medical procedures. Its design often includes a slight curve or specific tip shape to facilitate precise cutting in tight spaces, which is crucial for ensuring that sutures can be removed without causing additional trauma to the surrounding tissues.

The other options describe instruments that serve entirely different purposes. For instance, measuring pressure typically involves devices like sphygmomanometers and not scissors. Instruments that listen to heart sounds are stethoscopes, while hearing tests are conducted using audiometers. Therefore, the unique function of suture scissors aligns perfectly with the correct choice, distinguishing it clearly from these unrelated tools.
