Abstract

Systems and methods of image-based registration are disclosed herein. A method can include importing a pre-operative patient model and a statistical shape model, wherein the pre-operative patient model is associated with a patient's bony anatomy, pre-fitting the statistical shape model to the pre-operative patient model to generate a pre-fit model, and determining a transformation between the pre-fit model and the statistical shape model. Based on the determined transformation, the pre-operative patient model can be converted to a converted pre-operative patient model in an anatomic reference frame of the statistical shape model. A plurality of points on the bony anatomy in a tracker reference frame can be collected by a sensor and, based on the plurality of points, the pre-fit or converted pre-operative patient model can be registered to the tracker reference frame.

Abstract

Systems and methods of tensioning a joint are disclosed herein. Trackers are affixed to the anatomy of the joint and the joint is adjusted into a fixed pose. In the fixed pose, a force is applied to the joint using a joint tensioner. The force is measured by the joint tensioner while a tracking system simultaneous captures the displacement of the joint generated by the force. A force-displacement relationship is generated based on the measured force and the captured displacement. The force-displacement relationship is used to determine a patient-specific tensioning force and to perform surgical planning.

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

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.

A spatial frame apparatus for positioning on a patient to treat an injury. The apparatus includes a frame having one or more motorized struts. The motorized struts include one or more motors configured to cause movement of the motorized struts in one or more directions in accordance with a treatment plan. The apparatus includes one or more sensors and one or more processing components communicatively coupled to motorized struts and/or motors. The sensors obtain data related to operation of the frame, including at least one of: position and/or movement data associated with the patient and/or the frame, data associated with operational status of one or more components of the frame, external data, and/or any combination thereof. The data is sensed prior to, during and/or after one or more adjustments performed by the frame. The processing components determine an optimal time to perform adjustments by the motorized struts based on the obtained data.

Abstract

A probe for registering an anatomical surface for a registration procedure includes a probe shaft, a probe tip having a base end coupled to a distal end of the probe shaft, a contact ball disposed and configured to rotate within a contact end of the probe tip, and a biasing element disposed within the probe tip. The biasing element is configured to bias the contact ball toward the contact end of the probe tip and the contact ball is configured to, in response to external force against the contact ball, push against the biasing element. The probe is configured to generate a signal in response to the contact ball pushing against the biasing element.

Abstract

Controlling endoscopic light output. One example is a method of operating an endoscopic system, the method comprising: providing, from an endoscopic console, light to an endoscope at a first illumination level; receiving, by the endoscopic console, a first electronic image from a camera head associated with the endoscope; partitioning, by the endoscopic console, the first electronic image into a plurality of regions; calculating, by the endoscopic console, a value indicative of exposure for each region of the plurality of regions, thereby creating a plurality of values indicative of exposure; determining, by the endoscopic console, that a distal end of the endoscope is outside a body cavity, the determination based on the plurality of values indicative of exposure; and reducing, by the endoscopic console, the light provided to the endoscope to a second illumination level lower than the first illumination level.

Abstract

A motor module for use in a spatial frame is disclosed. Each of the motor modules being selectively attachable and detachable from a manually adjustable strut in a spatial frame. In use, with the motor modules detached, the struts can be manually adjusted to, for example, facilitate initial construction of the spatial frame in the operating room, to allow patients to manually adjust the struts if desired, etc. Thereafter, with the motor modules coupled to the struts, motorized and/or automated adjustment of the struts according to a treatment plan can be achieved. In use, each of the motor modules is configured to engage an actuation point positioned at the end of the manually adjustable struts.
