Medical Emitter/Detector Imaging/Alignment System And Method
US Patent:
2012002, Jan 26, 2012
Filed:
Apr 26, 2011
Appl. No.:
13/094524
Inventors:
David Chang - Rochester NY, US
Nicholas Ransom Powley - St. Paul MN, US
Andrew G. Fischer - Hopkins MN, US
Alan Fischer - Ames IA, US
Nicholas Ransom Powley - St. Paul MN, US
Andrew G. Fischer - Hopkins MN, US
Alan Fischer - Ames IA, US
International Classification:
A61B 6/00, H05G 1/64
US Classification:
600407, 378 988
Abstract:
Improved methods and apparatuses for imaging during medical procedures in accordance with various embodiments of the present invention include use of an image correction algorithm. In various embodiments, an original image of a region of interest where a medical procedure occurring along a particular axis will be performed is created with a beam emitter and a generally planar detector. Due to the emitter not being aligned orthogonal to the detector, the original image will be skewed. Using a known location and orientation of the detector, a location and orientation of the emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to perform the medical procedure while viewing an accurate corrected image in real-time.
Methods And Apparatuses For Vertebral Body Distraction And Fusion Employing A Coaxial Screw Gear Sleeve Mechanism
US Patent:
2012032, Dec 20, 2012
Filed:
Aug 22, 2012
Appl. No.:
13/591463

International Classification:
A61F 2/44
US Classification:
623 1716
Abstract:
Improved methods and apparatuses for vertebral body distraction and fusion in accordance with various embodiments of the present invention employ one or more coaxial screw gear sleeve mechanisms. In various embodiments, coaxial screw gear sleeve mechanisms include a post with a threaded exterior surface and a corresponding sleeve configured to surround the post, the corresponding sleeve having a threaded interior surface configured to interface with the threaded exterior surface of the post and a geared exterior surface. A drive mechanism can be configured to interface with the geared exterior surface of the sleeve, causing the device to distract.

International Classification:
G01T 1/161, H05G 1/06, H05G 1/00, H05G 1/10, H05G 1/24
US Classification:
606130, 606 97, 25036302, 25036307, 378102
Abstract:
Improved methods and apparatuses for inserting pedicle screws in accordance with embodiments of the present invention include an image correction algorithm. In various embodiments, an original image of a region of interest of a patient including a pedicle is created with an X-ray emitter and an X-ray detector. Due to the X-ray emitter not being aligned orthogonal to the X-ray detector, the original image will be skewed. Using a known location and orientation of the X-ray detector, a location and orientation of the X-ray emitter provided by a position monitoring system, and the original image, a processing system can execute the image correction algorithm to provide a corrected image to allow a surgeon to properly insert a pedicle screw along the axis of the pedicle while viewing an accurate corrected image in real time.

US Classification:
7442482, 7442471
Abstract:
An improved mechanism for expanding or lifting a device in accordance with various embodiments of the present invention is a coaxial screw gear sleeve mechanism. In various embodiments, coaxial screw gear sleeve mechanisms includes a post with a threaded exterior surface and a corresponding sleeve configured to surround the post, the corresponding sleeve having a threaded interior surface configured to interface with the threaded exterior surface of the post and a geared exterior surface. A drive mechanism can be configured to interface with the geared exterior surface of the sleeve, causing a device utilizing such a mechanism to expand or lift between a collapsed configuration and an expanded configuration.
