Which instrument is typically used to grasp the cervix during a vaginal hysterectomy?

The correct instrument used to grasp the cervix during a vaginal hysterectomy is the tenaculum. This surgical tool is designed with sharp, curved points that can efficiently secure and manipulate the cervix, allowing for better access and control during the procedure. The tenaculum's design enables the surgeon to firmly hold the cervix in place, making it easier to perform the necessary steps of the hysterectomy safely.

The Hegar dilator is primarily used for cervical dilation and is not intended for grasping. The Kelly clamp, while useful for clamping blood vessels or tissue, does not have the specific contour designed for holding the cervix. Pennington forceps, typically used to grasp uterine tissue or ligation, lack the pointed design and stability required for the cervix. Understanding the unique functions of these instruments is key in surgical practice, ensuring safety and effectiveness in procedures like a vaginal hysterectomy.
