What are thumb forceps primarily used for?

Thumb forceps are primarily used for holding and releasing tissue during surgical procedures. They are designed with two arms connected by a hinge that allows for a pinching action, which provides a firm grip without requiring significant pressure. This control is crucial in surgical settings, as it allows medical professionals to manipulate tissues with precision and stability while minimizing damage to delicate structures.

In contrast, the other options do not accurately reflect the primary use of thumb forceps. Cutting sutures is typically performed with scissors designated for that purpose. Measuring wounds usually involves specific measuring instruments designed for accuracy, rather than forceps. Cauterizing tissue is accomplished with specialized cauterizing tools or instruments, rather than with forceps.
