Forceps - Locking Forceps

Locking Forceps

Locking forceps, sometimes called clamps, are used to grasp and hold objects or tissue. When they are used to compress an artery to forestall bleeding they are called hemostats. Another form of locking forceps is the needle holder, used to guide a suturing needle through tissue. Many locking forceps use finger loops to facilitate handling (see illustration, below, of Kelly Forceps). The finger loops are usually grasped by the thumb and middle or ring fingers, while the index finger helps guide the instrument.

The most common locking mechanism is a series of interlocking teeth located near the finger loops. As the forceps are closed, the teeth engage and keep the instrument's grasping surfaces from separating. A simple shift of the fingers is all that is needed to dis-engage the teeth and allow the grasping ends to move apart. Forceps are also used for surgery.
