Apparatus and methods for balancing a joint
A joint replacement balancing system which provides real-time feedback to a surgeon during a joint replacement surgery to assist the surgeon to balance a joint replacement. The joint replacement balancing system includes a non-transitory processor-readable medium storing code representing instructions to cause a processor to receive a signal from a joint balancing apparatus, determine if the joint replacement is out of balance, determine a corrective course of action to bring the joint into balance and generate and display to the surgeon during the joint replacement surgery a recommended corrective course of action to complete the joint replacement surgery.
Method and tracking system for tracking a medical object
The disclosure relates to a method and a tracking system for tracking a medical object. Herein, image data obtained by an imaging method and a predetermined target position is acquired for the medical object. The image data is used to detect the medical object automatically by an image processing algorithm and track the position thereof in a time-resolved manner. Furthermore, it is furthermore indicated when, or that, the detected medical object has reached the target position. A plurality of the detected positions of the medical object and associated detection times are stored in a database.
SYSTEMS AND METHODS FOR IDENTIFYING AND FACILITATING AN INTENDED INTERACTION WITH A TARGET OBJECT IN A SURGICAL SPACE
An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to: detect an intent of a user of a computer-assisted surgical system to use a robotic instrument attached to the computer-assisted surgical system to interact with a target object while the target object is located in a surgical space; determine a pose of the target object in the surgical space; and perform, based on the detected intent of the user to interact with the target object and the determined pose of the target object in the surgical space, an operation with respect to the target object.
METHODS AND SYSTEMS FOR ASSISTING A USER IN POSITIONING AN AUTOMATED MEDICAL DEVICE RELATIVE TO A BODY OF A PATIENT
Provided are systems, devices and methods for assisting a user in positioning an automated medical device on, or in close proximity to, a body of a subject, by simulating the position and orientation of the medical device on one or more images of the subject, and providing the user with instructions regarding the actual positioning of the medical device and/or correction thereof, based on the simulated position and orientation.
PATIENT-SPECIFIC ADJUSTMENT OF SPINAL IMPLANTS, AND ASSOCIATED SYSTEMS AND METHODS
A computer system receives readings from sensors embedded in a spinal implant implanted in a patient during surgery. The sensor readings are indicative of a load applied by a spine of the patient on the spinal implant. The load causes physical discomfort to the patient. A feature vector is extracted from the implant sensor readings using a machine learning module. The feature vector is indicative of the physical discomfort caused by the load. Electrical signals are generated using the machine learning module based on the feature vector. The machine learning module is trained based on patient data sets to generate the electrical signals to balance the load, such that the physical discomfort is reduced. The electrical signals are transmitted to one or more actuators embedded in the spinal implant to cause the one or more actuators to configure the spinal implant, such that the load is balanced.
Patient-specific pre-operative planning
A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.
Surgical systems and methods for identifying tools guided by surgical robots
A surgical system for assisting a user in performing a surgical procedure at a surgical site, comprising a tool having a checkpoint, a pointer having a tip, and a localizer to determine a position of the pointer within a field of view. A memory comprises identification data associated with a plurality of tools. A controller is configured to prompt the user to position the tip of at the checkpoint, to receive position data from the localizer associated with the pointer within the field of view, to compare position data associated with the pointer against the identification data of the memory to determine an identity of the tool, and to present the user with the identity of the tool.
Spinal Rod Preparation Systems and Methods
The present disclosure provides systems and methods for preparing a spinal rod that enable the digital mapping of rod contours to produce spinal rods that conform to an ideal rod trajectory, which reduces spinal rod to screw head misalignment. Reducing spinal rod to screw head misalignment helps reduce a failure rate of spinal rods in patients. In invasive spinal fusion surgeries, a digital three-dimensional representation may be generated of a flexible rod formed to align with screws installed in the patient. In minimally invasive surgeries, a digital three-dimensional representation may be generated using pointers. A surgeon may adjust the digital three-dimensional representation via a graphical user interface. Bending instructions may be generated from the digital three-dimensional representation that direct how a spinal rod should be bent using a bending tool. The final spinal rod accounts for the anatomical environment around the screws installed in the patient.
Robotic navigation of robotic surgical systems
In certain embodiments, the systems, apparatus, and methods disclosed herein relate to robotic surgical systems with built-in navigation capability for patient position tracking and surgical instrument guidance during a surgical procedure, without the need for a separate navigation system. Robotic based navigation of surgical instruments during surgical procedures allows for easy registration and operative volume identification and tracking. The systems, apparatus, and methods herein allow re-registration, model updates, and operative volumes to be performed intra-operatively with minimal disruption to the surgical workflow. In certain embodiments, navigational assistance can be provided to a surgeon by displaying a surgical instrument's position relative to a patient's anatomy. Additionally, by revising pre-operatively defined data such as operative volumes, patient-robot orientation relationships, and anatomical models of the patient, a higher degree of precision and lower risk of complications and serious medical error can be achieved.
DETERMINING RELATIVE 3D POSITIONS AND ORIENTATIONS BETWEEN OBJECTS IN 2D MEDICAL IMAGES
Systems and methods are provided for processing X-ray images, wherein the methods are implemented as a software program product executable on a processing unit of the systems. Generally, an X-ray image is received by the system, the X-ray image being a projection image of a first object and a second object. The first and second objects are classified and a respective 3D model of the objects is received. At the first object, a geometrical aspect like an axis or a line is determined, and at the second object, another geometrical aspect like a point is determined. Finally, a spatial relation between the first object and the second object is determined based on a 3D model of the first object, a 3D model of the second object, and the information that the point of the second object is located on the geometrical aspect of the first object.
