Abstract
A traction system for automatically tracking and displaying parameters of a joint during surgery. The traction system includes a traction device and a computing device. The traction device has a proximal end and a distal end. The proximal end has a platform with a perineal post extending therefrom and the distal end has one or more footrests extended therefrom. One or more sensors are connected to the traction device. The one or more sensors generate sensor data based on movement of the traction device. A computing device is connected to the one or more sensors and is configured to receive the sensor data and process the sensor data into a metric. A display connected to the computing device is configured to display the metric.
Core Innovation
The invention describes a traction system that uses a traction device with a moveable component and one or more sensors directly attached to the traction device. The sensors generate sensor data based on movement of the moveable component, and a computing device receives and processes the sensor data into a first metric that is an angle of a patient's anatomy.
The traction system further includes a camera connected to the computing device and positioned toward the traction device. The camera generates camera data, which is processed via the computing device into a traction time metric, and a display connected to the computing device displays both the first metric and the traction time metric.
The computing device is programmed such that each of the first metric and the traction time metric has a threshold, and the display indicates when each respective threshold is exceeded. In one described implementation, the traction device includes a proximal end with a platform having a perineal post extending therefrom and a distal end having one or more footrests extended therefrom.
Claims Coverage
The document contains two independent claims. Across both independent claims, the main inventive features include sensor-generated anatomical angle metrics, camera-derived traction time metrics, and threshold-based indication on a display.
Sensor-generated anatomical angle metric on a traction system
A traction device having a moveable component with one or more sensors directly attached thereto, wherein the sensors generate sensor data based on movement of the moveable component; and a computing device connected to the one or more sensors and configured to receive the sensor data and process the sensor data into a first metric, wherein the first metric is an angle of a patient's anatomy.
Camera-derived traction time metric
A camera connected to the computing device and configured to be positioned toward the traction device, wherein the camera generates camera data which is processed via the computing device into a traction time metric.
Threshold-based indication for both metrics on a display
A display connected to the computing device configured to display the first metric and the traction time metric, wherein the computing device is programmed such that each of the first metric and the traction time metric has a threshold, and the display is configured to indicate if the respective threshold is exceeded.
Proximal platform with perineal post and distal footrests with sensor-generated movement data
A traction device having a proximal end and a distal end, the proximal end having a platform with a perineal post extending therefrom and the distal end having one or more footrests extended therefrom; one or more sensors directly connected to the traction device, wherein the one or more sensors generate sensor data based on movement of the traction device.
The independent claims cover a traction system that computes an anatomical angle first metric from sensor data, computes a traction time metric from camera data, and displays both metrics with threshold-based exceeded indications; one independent claim further specifies the proximal platform with a perineal post and distal footrests.
