An automated spatial frame is disclosed. The spatial frame may include a master controller unit arranged and configured as a centralized controller for exchanging data with a remote computing system, exchanging data with a plurality of automated struts, and delivering power to the automated struts. Thus arranged, the master-controller unit may be configured as a fully integrated, rechargeable power supply/controller unit for powering and controlling the automated struts. In one embodiment, the master-controller unit is coupled to an external surface of a platform. The platform acting as a conduit for coupling the master-controller unit to the automated struts. As such, at least one of the platforms provides integrated connectivity to the automated struts. In one embodiment, the struts may be wireless automated strut including a motor, a power source, and a wireless communications module for communicating with an external computing system.

Automated spatial frame and automated struts used therewith

A surgical system and method for markerless intraoperative navigation is provided. The system can includes a structured light system that can be utilized to intraoperatively sense three-dimensional surface geometry. The computer system is configured to segment a depth image to obtain surface geometry data of an anatomical structure embodied within the depth image, register the surface geometry data of the anatomical structure to a model, and update the surgical plan according to the registered surface geometry data. The surgical system is an endoscopic surgical system.

Markerless navigation system

An automated and/or motorized spatial frame including a control unit and a plurality of motorized struts is disclosed. The control unit being configured as a controller for exchanging data with an external computing system, exchanging data with the plurality of motorized struts, and delivering power to the motorized struts. Thus arranged, the control unit may be configured as a fully integrated power supply and controller for powering and controlling the motorized struts. In some embodiments, the control unit includes a plurality of PCB modules, each positioned within the spaces or pockets formed between adjacent tabs on a ring of the frame. The PCB modules being detachably coupled to the ring. In some embodiments, the PCB modules may be detachably coupled to the ring via interconnecting male and female connectors. Alternatively, the PCB modules may be detachably coupled to the ring via a plurality of brackets.

Methods and devices for bone adjustment, such as limb lengthening, are disclosed. For example, in one embodiment, a bone adjustment device may include a proximal portion configured to attach to a first bone portion, a distal portion configured to attach to a second bone portion, a motorized drive assembly, a control circuitry operably coupled to the motorized drive assembly, the motorized drive assembly and the control circuitry being hermetically sealed within a motor compartment, a driving element having a first end operatively coupled to the motorized drive assembly and a second end operatively coupled to the distal portion, the control circuitry is operative to receive wireless control signals from an external computing device, the motorized drive assembly is configured to be actuated based on the control signals to force rotation of the driving element to cause movement of the distal portion away from the proximal portion. Other embodiments are described.

Implantable motorized bone adjustment devices

Methods and systems for treating osteochondral defects (OCDs) are disclosed. The methods include collecting surface data of a joint using image-free methods, generating a three-dimensional (3D) healthy bone model based on the surface data and a database of healthy bone anatomies, defining a boundary of the OCD on the joint, and generating a 3D implant model based on the 3D healthy bone model and the boundary. The method may also include manufacturing an implant based on the 3D implant model, generating an implantation plan, resecting the joint according to the implantation plan, and placing the implant into the resected cavity. The 3D implant model may include a first and second porous layer separated by a nonporous layer. A polymer material is overmolded onto the second porous layer and treated to exhibit properties that mimic cartilage, while the first porous layer allows the implant to fuse to patient bone.
