SYSTEMS, METHODS, AND DEVICES FOR REGISTERING AND TRACKING ORGANS DURING INTERVENTIONAL PROCEDURES
20230090468 · 2023-03-23 ·

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using specialized catheters and inserts. A bend altering device is introduced into a conduit in an organ causing it to take on a tortuous path and to assist in its visualization. A scan is performed of a patient's anatomy to identify targets critical structures and the path of the conduit. A bend altering device containing position indicating elements is placed into the conduit in the same path as before the scan. During a procedure, the pre-procedure scans may be registered to the patient using the location of the position indicating elements in the conduit. This registration may be used in an intervention to guide instruments and templates to obtain diagnostic information or provide therapy to the targets identified in the scans.

DETERMINING RELATIVE ROBOT BASE POSITIONS USING EXTERNALLY POSITIONED IMAGERS

11660148 · 2023-05-30 · ·

Surgical systems and methods for tracking physical objects near a target site during a surgical procedure are provided, the surgical system employs a navigation system and a surgical instrument; an instrument tracker is provided on the surgical instrument and a patient tracker is provided on the patient's target tissue; the system and method is configured to detect an error condition compromising accuracy of the navigation guidance and to track and monitor a tool-to-bone offset.

Optical markers for calibration/alignment of medical diagnostic devices

Optical sensors and optical markers are placed on components in a medical system to provide calibration and alignment, such as on a patient transportation mechanism and spatially separated medical diagnostic devices. Image processing circuitry uses the data captured by these optical devices to coordinate their movements and/or position. This enables scans that were captured in multiple medical diagnostic devices to be accurately aligned.

OPTICAL TRACKING DEVICE WITH BUILT-IN STRUCTURED LIGHT MODULE

A system is disclosed that includes an optical tracking device and a surgical computing device. The optical tracking device includes a structured light module and an optical module that includes an image sensor and is spaced from the structured light module at a known distance. The surgical computing device includes a display device, a non-transitory computer readable medium including instructions, and processor(s) configured to execute the instructions to generate a depth map from a first image captured by the image sensor during projection of a pattern into a surgical environment by the structured light module. The pattern is projected in a near-infrared (NIR) spectrum. The processor(s) are further configured to execute the stored instructions to reconstruct a 3D surface of anatomical structure(s) based on the generated depth map. Additionally, the processor(s) are configured to execute the stored instructions to output the reconstructed 3D surface to the display device.
