US Patent:

6340363, Jan 22, 2002

Filed:

Sep 6, 2000

Appl. No.:

09/555885

Inventors:

Ciaran Bolger - Bristol, GB
Anthony J. Melkent - Germantown TN
Kurt R. Smith - Boulder CO

Assignee:

Surgical Navigation Technologies, Inc. - Louisville CO

International Classification:

A61F 504

US Classification:

606 90, 606102

Abstract:

A vertebral distractor is disclosed for use in performing anterior cervical spinal surgery. The vertebral distractor is associated with a computer controlled surgical navigation system employing an energy-detecting array to track positions of the vertebral distractor in three dimensional space relative to a known reference point. The guide comprises a shaft, a stationary first arm, and at least one movable second arm. At least one electrically energizable energy emitter array is attached to the shaft for use in identifying the location of the vertebral distractor relative to the vertebrae. A system for using the vertebral distractor in spinal surgery is disclosed.

International Classification:

A61B 505

US Classification:

600424, 606130, 378205

Abstract:

Apparatus and methods are disclosed for use within an image-guided surgical navigation system for the storage and measurement of trajectories for surgical instruments. An icon representing the real-time trajectory of a tracked instrument is overlaid on one or more pre-acquired images of the patient. At the surgeons command, the navigation system can store multiple trajectories of the instrument and create a static icon representing each saved trajectory for display. The surgeon may also measure a planar angle between any two trajectories. The angle is computed in the plane of the image, and therefore will be computed separately for each image displayed. Furthermore, the surgeon has the option of computing and displaying the three-dimensional distance between two points defined by any two trajectories.

International Classification:

A61B 500

US Classification:

600424, 600426, 606130

Abstract:

Apparatus and methods are disclosed for use within an image-guided surgical navigation system for facilitating the combined positioning and orientation of multiple surgical implements. A tool guide having multiple cannulas is tracked by a surgical navigation system in real time. Position data of the tool guide is registered and combined with pre-acquired images by the navigation computer. Concurrent graphical representations of the plurality of cannulas are superimposed over the images and displayed. The display allows the surgeon to place the tool guide into the patients body and position and orient the plurality of cannulas which are then used to place each of the implements.

Assignee:

SDGI Holdings, Inc. - Wilmington DE

International Classification:

A61B001/32

US Classification:

600210, 600214, 600215, 600233

Abstract:

Methods and devices retract tissue for minimally invasive surgery in a patient. A retractor includes a working channel formed by a first portion and a second portion. The first and second portions are movable relative to one another from a first configuration for insertion that minimizes trauma to skin and tissue to an enlarged configuration after insertion to further retract skin and tissue in a minimally invasive manner. Instruments are engageable to the first and second portions and operable to move the first and second portions relative to one another.

Assignee:

Surgical Navigation Technologies, Inc. - Louisville CO

International Classification:

A61B 5/05

US Classification:

600426

Abstract:

An apparatus and procedures for percutaneous placement of surgical implants and instruments such as, for example, screws, rods, wires and plates into various body parts using image guided surgery. The invention includes an apparatus for use with a surgical navigation system, an attaching device rigidly connected to a body part, such as the spinous process of a vertebrae, with an identification superstructure rigidly but removably connected to the attaching device. This identification superstructure, for example, is a reference arc and fiducial array which accomplishes the function of identifying the location of the superstructure, and, therefore, the body part to which it is fixed, during imaging by CAT scan or MRI, and later during medical procedures.

US Classification:

33512, 33836

Abstract:

A measurement instrument is provided with indicia extending therealong. The measurement instrument indicia is correlated with an indicator of a reference instrument. The measurement instrument is positionable adjacent the entry location of a portal into a patient when the reference instrument is in the portal. The indicator of the reference instrument is correlated to a target location in the patient, and a location of the indicator along the indicia provides an indication of the optimal length for a retractor to be positioned in the portal.
