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).
