Patent number: 7794467Abstract: Adjustable and modular systems, devices and methods for accurately cutting or resecting bones during surgery, particularly in preparation for installing joint implants during arthroplasties, including, but not limited to, preparation of femur or tibia during knee arthroplasties, such as total knee arthroplasty. The embodiments of the present invention provide solutions for adjusting a position of the cutting guides, or structures for guiding or directing the implements for resecting a patient's bone tissue, such as saws. The systems and devices comprise an adjustor for adjusting the cutting guide's position at the patient's bone in at least one degree of rotational freedom and in at least one degree of translational freedom.Type: GrantFiled: November 15, 2004Date of Patent: September 14, 2010Assignee: Smith & Nephew, Inc.Inventors: Brian J.

Publication number: 20070118055Abstract: Systems and methods for planning surgical procedures involving custom medical implants that can involve the selection, design and/or creation of custom medical implants and/or the selection, modification, and/or design of custom surgical procedures related to those implants. Certain embodiments allow implants to be selected, designed, created, or otherwise customized and then placed in patients using non-standard surgical techniques. The invention provides greater flexibility in implant use by allowing a surgeon to revise, create, or otherwise select surgical techniques for custom implants and, ultimately, provide better treatment in a greater variety of medical circumstances. Certain embodiments of the invention involve computer assisted surgery to provide for implant-related surgery involving non-standard surgical steps and/or implants.Type: ApplicationFiled: November 6, 2006Publication date: May 24, 2007Applicant: Smith & Nephew, Inc.Inventor: Daniel McCombs

Publication number: 20050279368Abstract: Input/Output systems and processes for computer assisted surgery systems are described. In one embodiment, a rendering apparatus is adapted to render display information on a presentation substrate during surgery. A plurality of location indicia are attached to the presentation substrate and a sensor senses the position and orientation of the location indicia. A computer functionality determines the position and orientation of the presentation substrate from the information from the sensor on the position of the location indicia. The computer functionality coordinates the rendering apparatus with the position of the display substrate so that the rendering apparatus renders display information onto the presentation substrate used in surgery.Type: ApplicationFiled: June 16, 2004Publication date: December 22, 2005Inventor: Daniel McCombs

Publication number: 20050228266Abstract: Methods and apparatuses for providing a reference array input device for use with a computer-aided surgical navigation system. A reference array input device according to an embodiment of the present invention is configured to provide a plurality of fiducial members comprising portions capable of being sensed by at least two sensors associated with the computer-aided surgical navigation system in order to determine position and orientation of the reference array input device by the system. The reference array input device can include a plurality of indicator detectors adapted to facilitate selection of a corresponding instruction associated with the computer-aided surgical navigation system. The reference array input device can also include a mount adapted to support the reference array input device adjacent to an object, a surgical instrument, or a joint replacement prosthesis.Type: ApplicationFiled: March 30, 2005Publication date: October 13, 2005Inventor: Daniel McCombs

Publication number: 20050197569Abstract: Methods and apparatuses for providing a patient-mounted navigational sensor for use in computer-aided surgery are disclosed. A navigational sensor according to embodiments of the invention includes at least two optical tracking cameras for sensing surgical references and a mount adapted to be attached to the bone of a patient. Because the sensor is mounted to the bone rather than to external apparatus, and is thus closer to the surgical references that it is tracking, it is less likely that line of sight issues due to an acute angle between the plane of the surgical reference and the sensor or due to medical personnel obstructing the path of the reference's signal. Because the navigational sensor is much closer to the surgical references being tracked than in a typical computer-aid surgery scenario, the required camera separation is greatly reduced. Other advantages also accrue from such sensor positioning, as related more fully in this document.Type: ApplicationFiled: January 24, 2005Publication date: September 8, 2005Inventor: Daniel McCombs

Publication number: 20050119639Abstract: Devices and processes for use in computer aided or computer navigated surgery include one or more fault interfaces interposed between an indicium and an item to be used during surgery such as a body part, tool, implant, trial or other structure or component. After the indicia have been registered into the system and surgery begun, it is sometimes the case that indicia can be inadvertently moved or dislodged in position and/or orientation relative to the body part. Fault interfaces according to various embodiments are designed to fail first, so that the indicia can be repositioned relative to the item without the need to reregister the indicia into the system relative to the item. The fault interfaces preferably include structure that allows the indicium to be repositioned relative to the item so that it does not need to be reregistered into the system. Frame attachments which can by easily manufactured at relatively low cost, are disposable, and which are manufactured for single use are disclosed.Type: ApplicationFiled: July 23, 2004Publication date: June 2, 2005Inventors: Daniel McCombs, Robert Thornberry, Jody Stallings

Publication number: 20050113659Abstract: A probe for data input for a computer-assisted surgical system, comprising a body; one or more movable fiducials operably associated with the probe; and one or more stationary fiducials operably associated with the probe; wherein the movement of the one or more movable fiducials relative to the one or more of the stationary fiducials triggers data input on a position or an orientation of the probe, or both. The probe is particularly suitable for minimally invasive surgery. Also provided is a method of using the probe to input data during computer-assisted surgery.Type: ApplicationFiled: November 24, 2004Publication date: May 26, 2005Inventors: Albert Pothier, Daniel McCombs
