A fixture for immobilizing a patient's head during a medical procedure is usable with a CT scanner. The fixture includes a skull clamp having detachable and adjustable radiolucent extensions. The radiolucent extensions include a body portion, a surgical pin holder assembly, and an attachment member. A first radiolucent extension includes a two-pin holder assembly. A second radiolucent extension includes a single-pin holder assembly. The attachment member of the radiolucent extension allows for angular adjustable attachment of the radiolucent extension to the skull clamp through corresponding starburst features. The surgical fixture may include an immobilization base unit having first and second mounting arms, a connecting arm, and a position adapter. The skull clamp with extensions attaches to the immobilization base unit to further immobilize the patient. The position adapter connects to the skull clamp and includes a rotational unit and vertical adjustment unit to position the patient as desired.
摘要:
A surgical fixture includes a skull clamp having a pair of arms. Each of the arms includes a rail having a generally “T”-shaped or dovetail-shaped cross section. An accessory attachment assembly comprises a gripping portion having a pair of jaws that are operable to selectively grip a rail. The accessory attachment assembly also includes a body portion having a feature for receiving surgical accessories. Surgical accessories may be rotated relative to the accessory attachment assembly along a first plane, and may further be secured to the accessory attachment assembly. The body portion may be rotated relative to gripping portion along a second plane. A mechanism is operable to simultaneously effect gripping with the jaws while preventing rotation of the body portion relative to the gripping portion. The mechanism is also operable to simultaneously release gripping of the jaws while permitting rotation of the body portion relative to the gripping portion.
