System for navigating a surgical instrument
The invention relates to a system for navigating a surgical instrument (1), comprising a processor configured for: obtaining a first 3D medical image of a first volume (V1) of a patient's body, said first volume (V1) comprising a reference marker (M), registering the first 3D image with said reference marker (M), obtaining a second 3D medical image of a second volume (V2) of the patient's body, said second volume (V2) being different from the first volume (V1) and not containing the reference marker (M) in its entirety, said first and second 3D images being obtained by a single imaging device, registering the second 3D medical image with the first 3D medical image, obtaining a virtual position of the surgical instrument (1) with respect to the reference marker (M) from a tracking system, determining a virtual position of the surgical instrument (1) with respect to the second 3D medical image.
Radiological imaging device
A radiological imaging device includes a gantry configured to perform radiological imaging and defining an area of analysis, a bearing structure supporting the gantry, and a robotic arm configured to move a medical instrument with respect to the area of analysis. The bearing structure includes a guide defining a translation axis substantially parallel to a longitudinal axis of the device, a first carriage connected to the gantry, and a second carriage connected to said robotic arm, the first and second carriages moving independently of each other, said gantry and said robotic arm configured to move along said translation axis.
Rotary motion passive end effector for surgical robots in orthopedic surgeries
A passive end effector of a surgical system includes a base connected to a rotational disk, and a saw attachment connected to the rotational disk. The base is attached to an end effector coupler of a robot arm positioned by a surgical robot, and includes a base arm extending away from the end effector coupler. The rotational disk is rotatably connected to the base arm and rotates about a first location on the rotational disk relative to the base arm. The saw attachment is rotatably connected to the rotational disk and rotates about a second location on the rotational disk. The first location on the rotational disk is spaced apart from the second location on the rotational disk. The saw attachment is configured to connect to a surgical saw including a saw blade configured to oscillate for cutting. The saw attachment rotates about the rotational disk and the rotational disk rotates about the base arm to constrain cutting of the saw blade to a range of movement along arcuate paths within a cutting plane.
Leveraging two-dimensional digital imaging and communication in medicine imagery in three-dimensional extended reality applications
A surgical system includes an XR headset and an XR headset controller. The XR headset is configured to be worn by a user during a surgical procedure and includes a see-through display screen configured to display an XR image for viewing by the user. The XR headset controller is configured to receive a plurality of two-dimensional (“2D”) image data associated with an anatomical structure of a patient. The XR headset controller is further configured to generate a first 2D image from the plurality of 2D image data based on a pose of the XR headset. The XR headset controller is further configured to generate a second 2D image from the plurality of 2D image data based on the pose of the XR headset. The XR headset controller is further configured to generate the XR image by displaying the first 2D image in a field of view of a first eye of the user and displaying the second 2D image in a field of view of a second eye of the user.
PROBE FOR IMPROVING REGISTRATION ACCURACY BETWEEN A TOMOGRAPHIC IMAGE AND A TRACKING SYSTEM
A medical apparatus includes a probe including a handle having a longitudinal axis, a distal tip disposed on the longitudinal axis, and a position sensor, which is disposed in the handle on the longitudinal axis at a predefined distance from the distal tip and is configured to output a signal indicative of a location of the probe. An alignment jig includes a connector configured to be fixed removably to the distal tip of the probe and three protrusions, which extend from the connector and are configured to contact a surface of a body of a patient at respective points, which are disposed in a plane perpendicular to the longitudinal axis when the connector is fixed to the distal tip of the probe.

Surgery system, contactless control panel for surgery system, and control method
A surgery system includes a contactless control panel, an infrared camera, a computer and a display. The contactless control panel includes control areas which are arranged in a predetermined pattern and are coated with infrared reflective material to reflect infrared radiation. The infrared camera captures an infrared image of the control areas. The computer performs image recognition on the infrared image, determines, based on the predetermined pattern stored in advance and a result of the image recognition, which one of the control areas is masked, and generates a device control signal based on a function corresponding to the one of the control areas that is determined to be masked. The display device displays images based on the device control signal.
REAL-TIME ADJUSTMENT OF HAPTIC FEEDBACK IN SURGICAL ROBOTS
Haptic feedback from a robotic surgical tool can be adjusted based on intra-operative assessment of the accuracy of a pre-operative surgical navigational plans. Navigational reference points are identified in at least one pre-operative image. At least one haptic response is identified for interactions between at least one robotic surgical tool and at least one navigational reference point. At least one intra-operative image is compared to the pre-operative image to determine the relative position of at least two corresponding navigational reference points in the images. The reference points' relative position determines a confidence level in the accuracy of the pre-operative navigational reference point. The haptic response is adjusted in timing, location, type, or amplitude based upon the confidence level. Tolerances and surgical navigation plan may also be updated and altered based on the confidence level.
Method and system for image processing to determine blood flow
Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the patient's heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient's heart and determine a fractional flow reserve within the patient's heart based on the three-dimensional model and the physics-based model.
Systems and methods for projecting an endoscopic image to a three-dimensional volume
A method comprises obtaining an endoscopic image dataset of a patient anatomy from an endoscopic imaging system and retrieving an anatomic model dataset of the patient anatomy obtained by an anatomic imaging system. The method also comprises mapping the endoscopic image dataset to the anatomic model dataset and displaying a first vantage point image using the mapped endoscopic image dataset. The first vantage point image is presented from a first vantage point at a distal end of the endoscopic imaging system. The method also comprises displaying a second vantage point image using at least a portion of the mapped endoscopic image dataset. The second vantage point image is presented from a second vantage point, different from the first vantage point.
