Abstract

An impactor and methods of operation of an impactor. The impactor includes an electromagnetic component that has a stationary electromagnetic housing and a moving magnet actuator, a striker, and one or more strike plates. The striker is coupled to an object. The stationary electromagnetic housing includes a coil that receives an electric current. The moving magnet actuator includes one or more magnets. The magnets generate a high potential magnetic field that interacts with the electric current applied to the coil disposed within the stationary electromagnetic housing and trigger translation movement of the moving magnet actuator. The electromagnetic field, generated as a result of application of the electric current to the coil, forces the moving magnet actuator to translate. Translation of the moving magnet actuator causes the moving magnet actuator to strike at least one of the strike plates to thereby translate the striker.

Abstract

A bone cutting device, such as a burr or saw blade, is irrigated to cool not only the bone cutting device itself, but also the bone of the subject on which a bone resection procedure is being performed. The bone cutting device can have one or more (e.g., a plurality of) internal flow channels that eject a cooling medium (e.g., water or an inert gas) from the bone cutting device. This emission of the cooling medium can not only flush bone chips from the resection site, thereby reducing frictional heating of the bone cutting device, but can also provide internal cooling to the bone cutting device while flowing through the one or more internal flow channels and also can cool the surface of the bone via conductive heat transfer (e.g., by the flow stream of the cooling medium impinging on the bone surface).

Abstract

Systems and methods for providing implant placement guidance in a shoulder procedure are disclosed. Tracking elements are affixed to a patient's scapula and humerus. The patient's shoulder is oriented into one or more orientations. Non-stressed positional data is collected based on a location and alignment of the tracking elements for each of the one or more orientations.

Abstract

An intramedullary (“IM”) nail and surgical technique or method. The IM nail includes a body including an opening for receiving a lag screw and a compression screw. The body further including one or more screw openings for receiving a bone screw. The surgical technique enables a surgeon to selectively prevent or allow movement (e.g., medialization) of the IM nail within the patient's intramedullary canal. The position of the IM nail can be selectively secured within the patient's intramedullary canal depending on surgeon preference and/or depending on the fracture pattern being treated. In use, the surgeon can elect to either secure the position of the IM nail within the patient's intramedullary canal thereby preventing movement (e.g., medialization) of the IM nail within the patient's intramedullary canal, or the surgeon can allow the IM nail to move (e.g., medialize) within the patient's intramedullary canal.

The method can include percutaneously attaching a tracking assembly to the patella, tracking the tracking assembly as the knee is moved through a range of motion; making an incision to open a joint capsule of the knee, everting the patella, reconfiguring the tracking assembly to reorient the tracking elements relative to the patella, and intraoperatively collecting data associated with the patella. The tracking assembly can be configured to use electromagnetic or optical tracking modalities.

Abstract

Delivery device and anchor combinations use sutures having a spliced transfer loop at one end. Each transfer loop is loaded with two or more suture tapes or repair sutures. The surgeon inserts the anchor loaded with the transfer loops into bone and then removes the delivery device from the anchor, leaving the anchor and the transfer loops behind in the bone. Removing the delivery device frees up more space within the internal volume of the anchor. Then, using the free end of the suture, the surgeon pulls the transfer loop through the anchor, thereby loading the two or more tapes or repair sutures into the free internal volume of the anchor. In this way, multiple suture tapes or repair sutures can be used with the smaller anchor in the repair of soft tissue.

In some examples, the tibial resection is perpendicular to the leg mechanical axis and an asymmetric tibial implant is used and/or the femoral resection is perpendicular to the leg mechanical axis and an asymmetric femoral implant is used. Other examples are described.

Abstract

An orthopedic template configured to assist surgeons in removing a tibial implant previously implanted within a patient's bone. In use, the template provides a reference that mimics the underlying support member of the previously implanted tibial implant. That is, the template provides a representation or footprint that mimics the configuration of the underlying support member of a tibial implant, which cannot be readily seen when the tibial implant is inserted into a patient's bone. For example, the template may include a superiorly extending structure or a visual image that mimics the underlying configuration of the support member of the tibial implant. In use, the template may be positioned on a superior surface of the tibial implant. Thereafter, an instrument such as a bone cutter, can be used to trace the representation formed on the template while simultaneously cutting or removing bone beneath the tibial tray.

Registering a three-dimensional bone model. Various examples are directed to methods and related systems of identifying surface features of a rigid structure visible in a video stream, and using the surface features to register a three-dimensional model for use in computer-assisted navigation of the surgical procedure. In some examples, the surface features are determined using touchless techniques based on a known or calculated motion of the camera. In other examples, the surface features are gathered using a touch probe that is not itself directly tracked. In yet still further examples, the three-dimensional model may be registered by use of a patient-specific instrument that couples to the rigid structure in only one orientation.

Abstract

Tissue repair systems which use knotless all-suture anchors and have the ability to lock multiple repair sutures within the anchor construct. The anchor construct includes a tension suture wrapped or looped upon itself to create an open eyelet, through which multiple repair sutures originating in soft tissue are passed. The location of the eyelet may be anywhere inside the all-suture anchor or adjacent to the exterior of the anchor body. Tensioning of the tension suture causes the eyelet to restrict movement of the repair sutures and secures them within or against the anchor body.
