Patent number: 11950852Abstract: Systems and methods are disclosed whereby a surface detection system is employed to obtain intraoperative surface data characterizing an exposed surface of the spine. In some embodiments, this intraoperative surface data is registered to segmented surface data obtained from volumetric data of the spine in order to assess the intraoperative orientation of the spine and provide feedback associated with the intraoperative orientation of the spine. The feedback may characterize the intraoperative spinal orientation as a change relative to the preoperative orientation.Type: GrantFiled: September 29, 2020Date of Patent: April 9, 2024Assignee: 7D SURGICAL ULCInventors: Michael K. K. Leung, Adrian Mariampillai, Beau Anthony Standish, Peter Siegler, Victor X. D. Yang

Patent number: 11754267Abstract: Alignment systems and devices are provided for controlling the alignment of an optical payload. In some embodiments, an optical positioning system is provided that includes a yoke supporting an optical payload. The yoke, which includes a plurality of articulated segments and associated pivot joints, is mechanically coupled to the optical payload, such that when the optical payload is oriented in a given direction, such as towards a distal target, the optical payload is rotatable about a distal pivot axis associated with a distal pivot joint of the yoke. The pivot joints of the yoke may be configured such that the rotation axis associated with a given pivot joint passes sufficiently close to a respective center of mass of a distalward portion of the optical alignment system beyond the given pivot joint, such that the position and orientation of the optical payload is maintained in the absence of external forces.Type: GrantFiled: December 6, 2016Date of Patent: September 12, 2023Assignee: 7D SURGICAL INC.Inventors: Adrian Mariampillai, Peter Siegler, Jean-Francois Paul, Michael Leung, Beau Anthony Standish, Victor X.

Patent number: 11712304Abstract: Various example embodiments of the present disclosure provide systems and methods for performing image-guided navigation during medical procedures using intraoperative surface detection. A surface detection device is employed to obtain intraoperative surface data characterizing multiple surface regions of a subject. Pre-operative volumetric image data is registered to each surface region, providing per-surface-region registration transforms. In some example embodiments, navigation images may be generated intraoperatively based on the dynamic selection of a suitable registration transform. For example, a registration transform for generating navigation images may be dynamically determined based on the proximity of a tracked surgical tool relative to the surface regions. In an alternative example embodiment, multiple navigation images may be displayed, wherein each navigation image is generated using a different registration transform.Type: GrantFiled: June 21, 2018Date of Patent: August 1, 2023Assignee: 7D Surgical ULC.Inventors: Michael K.

Patent number: 11605185Abstract: The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.Type: GrantFiled: September 14, 2020Date of Patent: March 14, 2023Assignee: 7D Surgical ULC.Inventors: Adrian Linus Dinesh Mariampillai, Peter Siegler, Michael Leung, Beau Anthony Standish, Victor X.

Patent number: 11547488Abstract: Systems and methods are provided for performing intraoperative fusion of two or more volumetric image datasets via surface-based image registration. The volumetric image datasets are separately registered with intraoperatively acquired surface data, thereby fusing the two volumetric image datasets into a common frame of reference while avoiding the need for complex and time-consuming preoperative volumetric-to-volumetric image registration and fusion. The resulting fused image data may be processed to generate one or more images for use during surgical navigation.Type: GrantFiled: July 4, 2017Date of Patent: January 10, 2023Assignee: 7D SURGICAL ULCInventors: Victor X.

Patent number: 10973581Abstract: Disclosed are systems and methods for obtaining a structured light reconstruction using a hybrid spatio-temporal pattern sequence projected on a surface. The method includes projecting a structured light pattern, such as a binary de Bruijn sequence, onto a 3D surface and acquiring an image set of at least a portion of this projected sequence with a camera system, and projecting a binary edge detection pattern onto the portion of the surface and acquiring an image set of the same portion of the projected binary pattern. The acquired image set of the binary pattern is processed to determine edge locations therein, and then employed to identify the locations of pattern edges within the acquired image set of the structured light pattern. The detected edges of the structured light pattern images are employed to decode the structured light pattern and calculate a disparity map, which is used to reconstruct the 3D surface.Type: GrantFiled: June 16, 2017Date of Patent: April 13, 2021Assignee: 7D SURGICAL INC.Inventors: Adrian Mariampillai, Kenneth Kuei-Ching Lee, Michael Leung, Peter Siegler, Beau Anthony Standish, Victor X.

Patent number: 10799315Abstract: Systems and methods are provided for use in image-guided surgical procedures, in which intraoperatively acquired surface data is employed to verify the correspondence between intraoperatively selected fiducial points and volumetric fiducial points, where the volumetric fiducial points are selected based on volumetric image data. Segmented surface data obtained from the volumetric image data is registered to the intraoperative surface data using the intraoperative and volumetric fiducial points for initial surface alignment, and this process is repeated for other permutations of the correspondence between the intraoperatively fiducial points and the volumetric fiducial points. Quality measures may be determined that relate to the registration quality for each fiducial correspondence permutation, where the quality measures may be employed to assess of the likelihood that the initially prescribed fiducial correspondence is correct.Type: GrantFiled: July 7, 2017Date of Patent: October 13, 2020Assignee: 7D SURGICAL INC.Inventors: Michael K.
