An anatomical gripping system comprising: a binding comprising: a substantially rigid spine; a calf shell mounted to the substantially rigid spine; an anterior shell; and a clamping mechanism connecting the anterior shell to the calf shell; wherein the calf shell comprises a flexible portion configured to selectively engage the superior portion of the calcaneus bone of a patient; and further wherein when the clamping mechanism applies a force to the flexible portion of the calf shell, the flexible portion of the calf shell is drawn into engagement with the superior portion of the calcaneus bone of the patient.

A surgical boot apparatus for use in surgery involving hip distraction includes a boot shell having a sole portion configured for placement adjacent a sole of a foot of a patient and a calf portion configured for placement adjacent a calf of the patient. The boot shell has a heel-receiving opening located between the sole portion and the calf portion and configured for receipt of a heel of the patient. A resilient pad is provided having a main portion configured for engaging an Achilles area of the patient. The main portion includes an end region that extends into the heel-receiving opening. The end region has an end edge that includes a notch configured for receipt of a calcaneus of the patient.

Various embodiments, aspects and features of the present solution encompass a manually adjustable patient positioning device that is configured to reside on an operating table and outside the sterile field of a surgical environment. A carriage assembly rides along a pair of parallel guide rails and supports a cushioning device. A patient's foot, for example, may be placed on the cushioning device such that repositioning of the carriage assembly along the guide rails causes manipulation of the position and degree of articulation for the patient's knee during an orthopedic surgery.

A limb support apparatus and corresponding methods for making same are disclosed. The limb support can comprise a shell for supporting a patient's limb during treatment, examination, and/or recovery. The shell can comprise at least one padding configured to protect the patient's limb. The padding can be secured to the shell using one or more mounting structures included in the padding. The mounting structures are configured such that they are received by corresponding mounting openings and/or features in the shell. An interference fit between the mounting structures and mounting openings/features secures the padding against the shell, thereby preventing the padding from inadvertently moving or sliding on the shell. Embodiments disclosed herein eliminate the need for traditionally used fasteners that are often difficult to clean and sterilize, thereby improving the quality of patient care and facilitating cleaning of patient and/or operating rooms.

Surgical methods and devices that facilitate registration of arthroscopic video to preoperative models are disclosed. With this technology, a machine learning model is applied to diagnostic video data captured via an arthroscope to identify an anatomical structure. An anatomical structure in a three-dimensional (3D) anatomical model is registered to the anatomical structure represented in the diagnostic video data. The 3D anatomical model is generated from preoperative image data. The anatomical structure is then tracked intraoperatively based on the registration and without requiring fixation of fiducial markers to the patient anatomy. A simulated projected view of the registered anatomical structure is generated from the 3D anatomical model based on a determined orientation of the arthroscope during capture of intraoperative video data. The simulated projected view is scaled and oriented based on one or more landmark features of the anatomical structure extracted from the intraoperative video data.

Systems and methods may be used to perform robot-aided surgery. A system may include a robotic controller to monitor a position and orientation of an end effector coupled to an end of a robotic arm. The robotic controller may apply a force to a bone using the end effector, such as via a soft tissue balancing component. The robotic controller may determine soft tissue balance using information from a tracking system, such as a position of a first tracker affixed to the bone. The soft tissue balance may be output, such as to a display device.

A cushioned support device includes a pad for supporting a portion of a patient's leg, a securing system coupled to the pad and configured to secure the portion of the patient's leg to the pad, and a connecting member coupled to the pad and configured to couple the cushioned support device to a second cushioned support device.

The present inventive subject matter describes a device and system for positioning, adjusting, and stretching a patient's extremity for surgical procedures where alignment is critical and minute adjustments may be required repeatedly. The device helps in maintaining the patient's extremity stationary, once the physician has selected the precise position for the elected procedure. The device uses using a combination of an articulating and a rotating frame, support plates and support rings that are attached to the extremity surgical positioning system. The system acts as a limb splint that is firmly attached to the surgical table. The support plates are attached to the patient via a series of adjustable straps preventing the extremity from moving independently of the support plate. A locking rack and gear configuration has adjustable locking pivot points that are positioned along and within the outer/inner proximal tube and outer/inner distal tube that lengthens or rotates various portions of the extremity.

A limb holder comprising: a mounting bracket for attachment to a surgical table; a mounting element comprising a spheroidal surface for attachment to said mounting bracket; a clamping assembly for providing a clamping engagement about said spheroidal surface of said mounting element, said clamping assembly comprising an upper jaw and a lower jaw, wherein said upper jaw and said lower jaw are biased towards one another so as to provide said clamping engagement about said sphereoidal surface of said mounting element; a limb support element mounted to said clamping assembly via a support rod; and a release mechanism mounted to said support rod and connected to said clamping assembly for selectively releasing said clamping engagement of said clamping assembly about said sphereoidal surface of said mounting element, whereby to allow said limb support element to be repositioned relative to said mounting element and hence repositioned relative to the surgical table.

A method for placing an implant on a patient in a robotic surgical procedure using a robotic system. During the robotic surgical procedure, a navigation system tracks the patient. The navigation system also provides information to the robotic system to guide movement of a cutting tool to remove material from the patient such that a cut surface is created to receive the implant. The implant is then robotically placed on the cut surface.
