Description
The MAYFIELD® Modified Swivel Adaptor (REF A-1115) is designed to provide all the
functionality of the standard swivel adaptor, and in addition offers a feature to tighten the
fit of the ratchet extension to the body of the skull clamp, when the adaptor is used with a
skull clamp. The tightened fit of the ratchet extension reduces motion that might be caused
by the tolerance differences of these two components, thereby minimizing movement of
the skull clamp during a surgical procedure. (In procedures such as image-guided surgery, or
procedures under a microscope, minimal or no movement of the skull clamp is desired.)

skull clamps and headrests (A-1011, A-1051, A-1012, A-1059, A-1108, and A-2000). It provides
optimal positional flexibility via 360-degree rotation as well as supplementary stability of
the skull clamp ratchet extension.
