The image processing unit creates projection image data based on measurement data that has been obtained by measuring an affected part of a patient, and thus creates a projection image as an image that is specified by the projection image data. This projection image is an image that is to be projected onto the patient, and includes an image that shows a state that the affected part is to be in after a surgical operation has started.Type: ApplicationFiled: September 14, 2015Publication date: August 3, 2017Applicant: KYOCERA Medical CorporationInventors: Shinya TSUSAKA, Masahiko HASHIDA

Publication number: 20170215967Abstract: Making a recommendation concerning a surgical procedure in a being is performed by a computer including a computer readable memory storing executable instructions and a processor in communication with the computer readable memory. The method includes a) acquiring information pertaining to the being and b) determining a recommendation pertaining to the being using the acquired information. In particular, the recommendation includes one of: a) one or more options for a new or replacement implant for inserting into the being; or b) a technique to be used for revision of an existing implant in the being. The method also includes transmitting, by the computer, the recommendation.Type: ApplicationFiled: February 1, 2017Publication date: August 3, 2017Inventor: William B. Spath

Publication number: 20170215968Abstract: The present invention relates to compensating for brain shift in catheter trajectory planning. First brain shift information is determined from an initial brain image dataset, an initial planning dataset, a patient orientation dataset, and first burr hole dataset. The brain image dataset is updated based on the first brain shift information and a trajectory of a first catheter is updated based on the updated brain image dataset. For a subsequent catheter placement, subsequent brain shift information is determined based on the updated brain image dataset, the patient orientation dataset, and a subsequent burr hole dataset. The brain image dataset is updated again based on the subsequent brain shift information. The re-updated brain image dataset is utilized to update trajectories of the subsequent catheter as well as any preceding catheters.Type: ApplicationFiled: August 6, 2014Publication date: August 3, 2017Inventor: Maria Inmaculada Rodriguez-Ponce

Publication number: 20170215970Abstract: A force exerted on a distal end of an elongate medical device can be determined. A graphical representation of the distal end of the elongate medical device and a graphical representation of the force exerted on the distal end of the elongate medical device can be computed. The graphical representation of the force can emanate from the graphical representation of the distal end of the elongate medical device. A first dimension of the graphical representation of the force can be increased in response to a longitudinal force being exerted on the distal end of the elongate medical device. A second dimension of the graphical representation of force can be increased in response to a lateral force being exerted on the distal end of the elongate medical device.Type: ApplicationFiled: April 29, 2015Publication date: August 3, 2017Inventors: Michael A. Quinn, Daniel R. Starks

Publication number: 20170215971Abstract: A system and method for tracking the three-dimensional position and orientation of a surgical instrument as the instrument is being utilized within the interior of a patient body. A stereoscopic camera system generates a stereoscopic image of the patient body which is subsequently rendered on a display device. A wireless signal transmitted by an electromagnetic field generator is received by a sensor on the surgical instrument. Utilizing this sensor data, a processor calculates the position and orientation of the surgical instrument and then superimposes upon the rendered stereoscopic image of the patient body a graphical representation indicative of the position and orientation of the surgical instrument.Type: ApplicationFiled: April 13, 2017Publication date: August 3, 2017Inventors: Abhishek GATTANI, Salmaan HAMEED

Publication number: 20170215973Abstract: A triggering device includes an optical fiber (126) configured for optical shape sensing. A supporting element (104) is configured to support a portion of the optical fiber. An interface element (106) is configured to interact with the optical fiber associated with the supporting element to cause a change in a property of the fiber. A sensing module (115) is configured to interpret an optical signal to determine changes in the property of the fiber and accordingly generate a corresponding trigger signal.Type: ApplicationFiled: September 16, 2015Publication date: August 3, 2017Inventors: MOLLY LARA FLEXMAN, ARYEH LEIB REINSTEIN, XINGCHI HE, PAUL THIENPHRAPA, DIRK DIJKKAMP, DAVID PAUL NOONAN

Publication number: 20170215974Abstract: Telerobotic, telesurgical, and/or surgical robotic devices, systems, and methods employ surgical robotic linkages that may have more degrees of freedom than an associated surgical end effector in space. A processor can calculate a tool motion that includes pivoting of the tool about an aperture site. Linkages movable along a range of configurations for a given end effector position may be driven toward configurations which inhibit collisions. Refined robotic linkages and methods for their use are also provided.Type: ApplicationFiled: April 14, 2017Publication date: August 3, 2017Inventors: William C. Nowlin, Paul W. Mohr, Bruce M.
