Filed:

May 19, 2000

Appl. No.:

09/575099

Inventors:

Martin Chin - Alameda CA

Assignee:

Walter Lorenz Surgical, Inc. - Jacksonville FL

International Classification:

A61B 1766

US Classification:

606105, 606 87, 606 90

Abstract:

An instrument for mobilizing the midface bones of a human skull in which at least a partial osteotomy between the midface bones and the skull has been performed. A first member includes a dentition engaging portion for engaging the dental arch of the maxilla. A second member includes a nasal engaging portion for engaging the nasal floor of the nasal cavity. An adjustable member is connected to the first member and to the second member and is adjustable to draw the first and second members toward each other so that the first member can be drawn against the dental arch and the second member can be drawn against the nasal floor. A lever is connected to at least one of the first and second members. The lever is disposed anteriorly of the forehead and extends in a superior-inferior direction relative to the skull when the first and second members are engaged with the dental arch and nasal floor, respectively. Simultaneously pulling the lever anteriorly and pushing the forehead posteriorly breaks the midface bones free from the skull.

Martin Chin - Alameda CA

International Classification:

A61B 1786

US Classification:

606 73

Abstract:

An apparatus and method for osteogenesis distraction of small alveolar bone is provided. The alveolar distraction osteogenesis device may be affixed to small and thin bone segments. An alveolar distraction osteogenesis device according to the first embodiment includes a submergible first and second members along with a threaded rod. An alveolar distraction osteogenesis device according to a second embodiment includes an osseointegrated cylindrical member along with an adaptable threaded rod which may be used with a stabilizing plate. The alveolar distraction osteogenesis device is activated using a hexagonal drive wrench or a slot screw driver. In order to allow for bone growth and/or distraction, a constant activation rate between bone segments is applied by a torque.

Inventors:

Martin Chin - Alameda CA

International Classification:

A61B 1766

US Classification:

606 53

Abstract:

An apparatus and method for submergible self-retaining distraction osteogenesis is provided. Distraction osteogenesis devices are submerged below a layer of tissue and/or skin layers and are activated based upon maximum pressures, rather than constant activation rates. Distraction osteogenesis devices are also self-retaining in that the force in displacing bone segments is transferred substantially through metal plates, rather than screws or fixation points. In particular, zygomatic, alveolar and mandibular distraction osteogenesis devices are provided. The zygomatic and alveolar distraction osteogenesis devices include a submergible first and second metal plate along with a threaded rod. The zygomatic and alveolar distraction osteogenesis devices are activated using a cannula, torque wrench adapter and torque wrench. The mandibular distraction osteogenesis device includes a palate expander having a plurality of rods used in coupling first and second self-retaining U-shaped plates.

Appl. No.:

15/200443

Inventors:

Martin Chin - Corte Madera CA, US

International Classification:

A61B 90/14

Abstract:

A head frame apparatus is secured to a human head during maxillofacial surgery and includes devices to easily position and secure an endotracheal (breathing) tube and an anesthesia delivery circuit for the patient that reduces the likelihood that the flow of oxygen through the tube is restricted thereby reducing the risk of severe injury or death. The head frame apparatus also includes a removable reference indicator, which may be easily attached and removed while identifying a reference point of the patient's face. Also the reference indicator includes a universal joint and pointer with an attached ruler. A transport apparatus positions multiple preset reference indicators and allows for preoperative transportation and removal, while protecting the preset reference indicators from inadvertent adjustment. A bendable reference indicator used in an articulator for preoperative modeling allows for easily identifying reference points in a cast model. An orbiting segment apparatus positions a portion of a cast of a jaw in relation to a condyle ball of the articulator.
