Abstract

Methods, non-transitory computer readable media, and ultrasound imaging apparatuses and systems that facilitate improved ultrasound imaging that emphasizes structures of interest are disclosed. With this technology, position data for a transducer assembly is continuously obtained along with ultrasound scan data captured via the transducer assembly. Image processing techniques are applied to ultrasound images generated from the ultrasound scan data to identify structure(s) of interest included therein and highlight the identified structures on a composite representation generated from the ultrasound images. The intensity of portions of the resulting composite representation is then adjusted to reflect the time in which the associated ultrasound scan data was captured. The composite representation is then output to an augmented reality headset or superimposed over an image of the patient to facilitate improved visibility and relation of the structures of interest.

Abstract

A suture/anchor and delivery device combination includes a first cannulated suture and a second stepped or staged suture that has a smaller diameter section connected to a larger diameter section. The smaller diameter of the second suture is passed through the first suture and the assemblage of sutures is further passed through a tube which acts as an inserter. To actuate the device, the larger diameter of the second suture is pulled into the lumen of the first suture, thereby expanding the first diameter of the first suture to create an interference fixation within bone.

A cutting guide for resecting a portion of a patient's bone such as, for example, a humeral head of a patient's humerus. The cutting guide including a body component, a cutting slot component including a cutting slot configured to receive a cutting instrument for resecting the portion of the patient's bone, a ball-joint coupling or clamping mechanism for coupling the cutting slot component to the body component, and a quick release mechanism moveable between a first position and a second position. In the first position, the release mechanism applies a clamping or spring force on the ball-joint coupling or clamping mechanism to inhibit movement of the cutting slot component relative to the body component. In the second position, the release mechanism releases the clamping or spring force on the ball-joint coupling or clamping mechanism so that the cutting slot component can be moved (e.g., rotated) relative to the body component.

Abstract

An impactor and methods of operation of an impactor. The impactor includes an electromagnetic component having a stationary electromagnetic housing and a moving armature component. The housing includes a coil that receives an electric current resulting in generation of an electromagnetic field for triggering translation of the armature within the housing. The impactor includes a striker body coupled to the armature. The striker body includes a distal end. The impactor includes a strike chamber having an interior and a distal strike wall disposed at a distal end of the chamber, and a spacer disposed at a proximal end of the chamber and opposite the distal strike wall. The electromagnetic field forces the armature and the striker body to translate in at least one direction. Translation of the armature causes the distal end of the striker body to strike at least one of the distal strike wall and the spacer.

Abstract

The disclosed Retrieval Augmented Generation systems and methods include a system with several components. First, a user interface generates a query for a large language model (LLM). The system features prompt generator circuitry that accesses a database containing documents, each with priorities linked to various factors. This circuitry retrieves context and factor priorities from these documents in response to the query. The system also includes an LLM interface that submits a query to the LLM, incorporating the original query, retrieved context, and factor priorities. The system then receives a response from the LLM, which includes data related to the documents and factor priorities. Finally, an output interface presents the user with response data from the LLM, detailing information about the documents and the retrieved factor priorities.

The orthopedic augment has, on an internal surface (2) thereof, cement fixation features (3) that receive an orthopedic cement therein and aid in resisting separation of the orthopedic prosthesis from the orthopedic augment. In addition, the orthopedic augment may include mechanical fixation mechanisms to engage the orthopedic prosthesis. Thus arranged, the orthopedic augment provides greater flexibility, in that it can be used in the form of a cone (e.g., cemented fixation) or a sleeve (e.g., mechanical fixation).

Abstract

Methods, non-transitory computer readable media, and surgical computing devices are illustrated that improve surgical planning using machine learning. With this technology, a machine learning model is trained based on historical case log data sets associated with patients that have undergone a surgical procedure. The machine learning model is applied to current patient data for a current patient to generate a predictor equation. The current patient data comprises anatomy data for an anatomy of the current patient. The predictor equation is optimized to generate a size, position, and orientation of an implant, and resections required to achieve the position and orientation of the implant with respect to the anatomy of the current patient, as part of a surgical plan for the current patient. The machine learning model is updated based on the current patient data and current outcome

A surgical system receives one or more initial transfer functions and one or more preoperative input factors for a patient and generates a surgical plan comprising one or more patient-specific implant parameters based on the one or more initial transfer functions and the one or more preoperative input factors for the patient. The surgical system further receives one or more intraoperative input factors for the patient and updates the one or more patient-specific implant parameters based on the one or more intraoperative input factors for the patient. An implant for the patient is selected based on the one or more updated patient-specific implant parameters.
