Certified Instrument Specialist (CIS) Practice Exam

Profunda clamps are specifically designed for vessel control during surgical procedures. Their primary purpose is to occlude blood vessels, which helps minimize blood loss and maintains a clear surgical field. This capability is crucial when performing surgeries that involve significant vascular structures, as it enhances the surgeon's ability to perform procedures safely and effectively.

While holding tissues in place is an important function of surgical instruments, that role is typically fulfilled by other types of clamps or instruments, such as tissue forceps or hemostatic clamps. Cutting through bone is accomplished with specialized tools like bone saws or chisels, which are designed for that purpose and not related to the function of profunda clamps. Additionally, suturing wounds involves the use of needle holders and suturing instruments rather than clamps, which are not designed for that specific task.
