Abstract
A maxillofacial or cranial-facial surgical stabilizer comprising a head frame fully or partially surrounding the head of a patient at an angle running from ears to temple, and that is fixated to the skull of the patient by multiple screws and/or ear holders and screws. One or more flexible/locking arms are removably attached to the head frame for holding and positioning a plurality of interchangeable instruments or accessories. One flexible/locking arm is a medial/center arm accessorized with a dental arch mold. A method of using a head frame to position the pieces of bones during maxillofacial or cranio-facial surgery is also provided.
Claims15
A maxilla/cranial-facial surgical stabilizer for use during maxilla/cranial-facial surgery, comprising:
- a metal frame configured to be fixated to a skull of a patient to establish a fixed frame of reference there about;
- at least three flexible arms each attached at one end to said frame and protruding from said frame to a distal end, each of said flexible arms having a fully flexible state of omnidirectional flexibility along its entire length for bending to a desired orientation a rigid state along its entire length, and a locking mechanism for locking said flexible arm in said rigid state at a desired orientation, and a mounting receptacle at the distal end of each of said flexible arms configured for removable attachment of one of the maxillofacial surgical aids, such as, a dental arch mold or template, a clamp, a holder or a tissue retractor;
- whereby said maxilla/cranial-facial surgical stabilizer may be fixated to a skull of a patient and each of said arms bent to and locked in a desired orientation relative to said fixed frame of reference to allow the said maxillofacial surgical aids to support, orient and stabilize the bony structures and/or segments thereof, relative to said skull of said patient.
A maxilla/cranial-facial surgical stabilizer for use during maxilla/cranial-facial surgery, comprising:
- a head frame formed as a rigid ring at least partially encircling a patient's head to establish a fixed frame of reference there about;
- at least three flexible locking arms, each said flexible locking arm further comprising
- an adjustable base joint at one end configured for releasable attachment to said head frame,
- a mounting socket at another end for releasable attachment of a surgical device chosen from among the group of a dental arch mold or template, a holder and a tissue retractor,
- a flexible arm extending between said base joint and said mounting socket formed of a plurality of flexible locking joints and having a fully flexible state of omnidirectional flexibility along its entire length for bending to a desired orientation, and a rigid state along its entire length, and
- a tensioner mounted on said flexible arm for adjusting tension of said flexible arm along said plurality of flexible locking joints and locking said flexible arm in said rigid state at a desired orientation;
- and
- one of a dental mold, clamp, holder or tissue retractor attached to the mounting socket of each flexible locking arm.
