DEVICE AND METHOD FOR POSITIONING A JOINT
The present invention relates to a joint positioning device for positioning a joint and methods for using such devices. The joint positioning device may comprise a patient support comprising a substantially flat surface, the patient support configured to be positioned on a medical examination table; a first leg and a second leg extending from the patient support, the legs configured to immobilize the patient support to the medical examination table in a lateral or longitudinal direction. The joint positioning device may further comprise a vertical pillar or pole, the vertical pillar or pole oriented substantially perpendicular to the substantially flat surface of the patient support, the vertical pillar or vertical pole extending in an opposite direction from the first leg and the second leg.
DEVICES AND METHODS FOR SUPPORTING A PATIENT'S LEGS
A foot holding assembly that includes a boot configured to hold the foot of the patient, a rigid sole coupled to the boot, a pivot arm having a first end rotatably coupled to the sole, a slider block pivotally coupled to a second end of the pivot arm and configured to be slidably mounted to a rail. The slider block includes a segmented body including a pair of longitudinal segments and a lateral segment, and a retainer disposed at an lateral interface of the pair of longitudinal segments and the lateral segment, wherein the retainer is configured to receive a second end of the pivot arm, wherein the pair of longitudinal segments and the lateral segment of the segmented body are each configured to move relative to one another in response to insertion of the second end of the pivot arm into the retainer.
Surgical Leg Positioner
A surgical leg positioner capable of bending the knee in varus or valgus while simultaneously distracting the tibia from the femur, the leg positioner having a thigh clamp module, a swing arm module connected to the thigh clamp module in a manner that offsets a joint axis laterally to the side of the knee of the patient so as not to damage the opposite compartment of the knee when bent in varus or valgus. The swing arm module also distracts the knee simultaneously when the knee is bent in varus or valgus. The swing arm module also permits flexion and extension of the knee at the knee's natural flexion-extension axis. The surgical leg positioner also utilizes a thigh brace that property aligns the leg on the surgical leg positioner.
Articulating Patient Positioning Apparatus
An apparatus comprises means for engaging a patient platform. The means comprises at least one layer of laminar sheeting of radiolucent material. At least one anatomical support member which comprises at least one layer of laminar sheeting of radiolucent material. At least one articulating joint unit is in engagement with the at least one of anatomical support member. The at least one articulating joint unit comprise at least one layer of laminar sheeting of radiolucent material with a primarily non-metallic connector at a central pivot point. The at least one articulating joint unit is positionable in at least a vertical and horizontal orientations enabling positioning of portions of an anatomy in three dimensions along x, y, and z axes. At least one primarily non-metallic locking member is configured to lock the at least one articulating joint unit at selectable position(s), in which a load bearing stress is spread across lengths of the laminar sheeting to mitigate a susceptibility to stress fractures and load failure.
System and method for patient positioning in an automated surgery
The present solution is generally directed to a patient positioning system used to position body parts, such as a knee, during a medical or surgical procedure. Further, the present solution is generally directed to a system and method for establishing and tracking virtual boundaries, and controlling a patient positioning system to adjust those virtual boundaries to facilitate an automated surgery procedure. Further, the present solution is generally directed to the synergistic combination of an autonomous patient positioning sub-system with a robotic surgical manipulator sub-system.
Articulating patient positioning apparatus
An apparatus having at least one anatomical support member which comprises at least one layer of laminar sheeting and at least one articulating joint unit is in engagement with the at least one of anatomical support member. The joint is positionable in at least a vertical and horizontal orientations enabling smooth positioning of portions of an anatomy in three dimensions such that translational and/or rotational centrepoints in its x, y and z axes substantially coincide. The joint is preferably made of by material(s) that do not cause substantial radiographic or nuclear imaging artifacts when medically imaged thereby.
SYSTEMS, DEVICES, AND METHODS FOR TESTING SUTURE PERFORMANCE UNDER STATIC AND DYNAMIC CONDITIONS
A system for testing sutures includes a test bench having a rotatable table, a framework supporting the test bench and the rotatable table above a surface, and a continuous passive motion (CPM) machine mounted on the rotatable table. The CPM machine is configured to rotate between a first position in which the CPM machine is upright and located above the rotatable table and a second position in which the CPM machine is inverted and located below the rotatable table. The system includes a fluid supply subsystem for directing an infusion fluid toward the CPM machine, a pump for circulating the infusion fluid in the fluid supply subsystem, a heat exchanger for heating the infusion fluid, a fluid collection tray located below the CPM machine and the rotatable table, and a pressure monitoring subsystem for monitoring a pressure level of the infusion fluid.
Devices and methods for supporting a patient's legs
A foot holding assembly for securing a foot of a patient during a surgical or diagnostic procedure includes a boot configured to hold the foot of the patient. In addition the assembly includes a rigid sole coupled to the boot. Further, the assembly includes a pivot arm having a first end rotatably coupled to the sole with a rotatable coupling configured to allow the sole to rotate relative to the first end of the pivot arm about an axis oriented perpendicular to the sole. The rotatable coupling includes an incremental locking mechanism including a locked position and an unlocked position. When the incremental locking mechanism is in the locked position, the rotational position of the sole about the axis is releasably locked. When the incremental locking mechanism is in the unlocked position, the sole is free to rotate relative the first end of the pivot arm only about the axis.
INTERACTIVE ANATOMICAL POSITIONER AND A ROBOTIC SYSTEM THEREWITH
A system and method are provided for improving the positioning of a target anatomy relative to a robot to perform a medical procedure. The system and method is especially advantageous for complex procedures that require a large operational workspace and/or several manipulator orientation changes to execute a surgical plan in its entirety such as total knee arthroplasty (TKA), as well as any of a wide variety of other surgical procedures, orthopedic or otherwise, including hip arthroplasty, ligament reconstruction, and shoulder arthroplasty. Dynamic and controlled repositioning of the target anatomy promotes robotic surgical system access in a way that any static positioning of the target anatomy cannot thereby speeding a surgical process and extending the spatial range of operation of the robot and tools carried thereon.
METHOD OF FLUOROSCOPIC SURGICAL REGISTRATION
Methods and systems for x-ray and fluoroscopic image capture and, in particular, to a versatile, multimode imaging system incorporating a hand-held x-ray emitter operative to capture digital or thermal images of a target; a stage operative to capture static x-ray and dynamic fluoroscopic images of the target; a system for the tracking and positioning of the x-ray emission; a device to automatically limit the field of the x-ray emission; and methods of use and use of such systems to register a virtual model of an anatomic structure to the corresponding anatomic structure.
