Publication number: 20110172494Abstract: Various embodiments of the present invention provide a surgical retractor having two blade-supporting arms, which are mounted to be laterally slideable towards and apart from each other by a toothed rack. Each arm supports a respective retractor blade. In some embodiments, the retractor blades are curved in the same direction as each other so that the first blade is concave in the first direction, and a second blade is also concave in the same direction. Alternatively or additionally, in some embodiments, a cushioned material or cushioned sleeve is present on the blades where the blades contact the anatomy. The cushioned material or sleeve may be made of a soft silicone. Further, the cushioned material or sleeve may be coated or molded onto the blade structure, or may be a removable sleeve that is manually slid onto or off of the blade structure. Also, alternatively or in addition in some embodiments, blade-mounted lighting may be provided.Type: ApplicationFiled: January 12, 2011Publication date: July 14, 2011Applicant: TEDAN SURGICALInventors: Daniel Bass, Ray Bertolero, Terry Johnston, Danny Fishman

Patent number: 7139601Abstract: A system for use during a medical or surgical procedure on a body. The system generates an image representing the position of one or more body elements during the procedure using scans generated by a scanner prior or during the procedure. The image data set has reference points for each of the body elements, the reference points of a particular body element having a fixed spatial relation to the particular body element. The system includes an apparatus for identifying, during the procedure, the relative position of each of the reference points of each of the body elements to be displayed. The system also includes a processor for modifying the image data set according to the identified relative position of each of the reference points during the procedure, as identified by the identifying apparatus, said processor generating a displaced image data set representing the position of the body elements during the procedure.Type: GrantFiled: April 12, 2001Date of Patent: November 21, 2006Assignees: Surgical Navigation Technologies, Inc., St. Louis UniversityInventors: Richard D.

Patent number: 6616604Abstract: A surgical retractor securing apparatus includes an adjustable securing device which attaches the apparatus to the surgical accessory bar of a halo style head fixation device and a capture assembly that releasably engages the elasticized band of a scalp hook retractor. The adjustable securing device compressively grips along a portion the length of a surgical accessory bar or otherwise attaches to an external support, providing a plurality of attachment points. The capture assembly may include a pivotable cam that releasably grips the elasticized band of a scalp hook retractor by compressing the band between the gripping cam and the surgical accessory bar or other external support.Type: GrantFiled: April 5, 2002Date of Patent: September 9, 2003Assignee: Allegiance CorporationInventors: Daniel Bass, Udo Wiedenmaier

Publication number: 20020198533Abstract: The invention disclosed herein relates to a site preparation guide for use in conjunction with intervertebral implants. In particular, the site preparation guide contains a hollow body, lumen and interior surface adapted to accommodate and control the positioning of a surgical tissue removal device during the creation of the implant site. The site preparation guide of the invention can further include side openings through the body of the guide to accommodate and control the positioning of a surgical drill, an integrated intervertebral distractor, and a distal endplate which serves as a drilling template for an implant having a corresponding endplate. The site preparation guide is a unitary, one-piece, sterilizable device. Also disclosed herein is a method of preparing an orthopedic intervertebral site using the site preparation guide of the invention and surgical kit including the guide.Type: ApplicationFiled: April 3, 2002Publication date: December 26, 2002Inventors: Fred Geisler, Michael Foster, Daniel Bass, Thomas Wiedenmaier, Terry Johnston

Patent number: 6042540Abstract: A surgical retractor with interchangeable retractor blades allows the retractor blades to be positioned in an incision before being side-loaded into the retractor body and locked in place. The surgical retractor uses a connector head with a circumferential groove that fits in a side-loading socket and is locked in place with a cam that fits in the circumferential groove. A release lever releases the cam and allows the retractor blades to be removed.Type: GrantFiled: August 18, 1997Date of Patent: March 28, 2000Assignee: Pacific Surgical Innovations, Inc.Inventors: Terry Johnston, Thomas Wiedenmaier, Daniel Bass, Todd Pope

Patent number: 5654642Abstract: A system and method for testing underground electric cables, while in service, for active corrosion and degree of neutral loss. The method is conducted by applying a non-harmonic selected frequency signal to the neutral(s) of the underground cable connecting a pair of structures, e.g., power transformers, from a variable frequency generator of the system. The test is conducted by a surveyor wearing foot electrodes which contact the earth as the surveyor walks along the earth over the cable in close interval steps. At each step, direct current (DC) potentials are monitored by a voltmeter between a copper-copper sulfate electrode carried by the surveyor and brought into contact with the ground at each step and the transformer ground. The potential of the gradients between the foot electrodes at the selective frequency and at the native alternating current (AC) is also measured by the voltmeter. These measurements are recorded at a stationary location on a digital data logger and/or computer.Type: GrantFiled: December 12, 1995Date of Patent: August 5, 1997Assignee: Henkels & McCoyInventors: Craig Daniel Bass, Richard Donald Valenti, Jr., Emer Cox Flounders, Jr.
