Abstract

Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

Abstract

Disclosed are systems and methods for a computerized framework that provides novel mechanisms for arthroscopic applications using real-time blood flow information. The disclosed framework operates by determining a real-time (or near real-time or substantially simultaneous) visualization of blood vessels or perfusion within anatomical structures during intraoperative procedures, and leveraging this determined information for the performance of an arthroscopic procedure. The disclosed framework can enable an arthroscopic camera to see blood flow and perfusion in tissues in real-time, which allows for differentiation of various parts of the anatomy that may otherwise be undetectable.

Abstract

The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.

Abstract

Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

Abstract

Methods, non-transitory computer readable media, and surgical computing devices that more effectively protect anatomical structures from resection during surgical procedures are disclosed. With this technology, a virtual protection area is defined in a reference frame by extending a line defined by an obtained set of coordinates in the reference frame in at least one direction. The reference frame is of a bone to be resected during a surgical procedure. Resection equipment is tracked during the surgical procedure to obtain a location of the resection equipment in the reference frame. A determination is made when the obtained location of the resection equipment is within the defined virtual protection area. The resection equipment is disabled when the determination indicates the obtained location is within the defined virtual protection area. Accordingly, this technology advantageously allows a surgeon to intraoperatively establish a protection area to facilitate automated protection of particular anatomical structures from resection.
