The present application proposes a chest and abdominal respiration signal decoupling and reconstruction method based on millimeter wave radar. Using a millimeter wave multiple-input multiple-output radar device, the radar echo is first mapped to a three-dimensional space using 3D beamforming technology, mapping the one-dimensional time domain signal to a spatial energy heat map containing distance, azimuth, and elevation three-dimensional information. Then, through spatial filtering strategy, the physiological vibration source signal clusters of the subjects with coupling relationship are separated. When the physiological vibration source includes the chest reflection area of the first anatomical site and the abdominal reflection area of the second anatomical site, combined with the adaptive best point selection algorithm, according to the anatomical features of the human body, the chest reflection area and the abdominal reflection area are physically located and distinguished in the three-dimensional space, and the independent breathing waveform is extracted from the body surface reflection to perform high-precision spatial separation and anti-interference waveform extraction operation of chest and abdominal respiration movement. The present application can realize high-precision spatial separation and anti-interference waveform extraction of chest and abdominal respiration movement.

The present invention includes a method for targeted isolation, segmentation, and coloring of anatomic images, anatomic maps, points of interest, and regions of interest for dynamic, translated form generation. For example, this invention includes a method whereby a description of anatomy that includes an anatomic site, and optionally laterality and other descriptors, targets and isolates diagrams from an anatomic map library that fits the anatomy description. A point of interest on a layered, hierarchical map is visualized in relation to the borders of each isolated anatomic site above, below, on the same level along with translated human readable descriptions of the pin position relative to each layer. An anatomic region of interest is also visualized in relation to sites above, below, and on the same hierarchical or layer level. Targeted isolation of each layer provides visualization, translation, descriptions, and visual selection points for a visual, translated hierarchical travel method included in this invention. A dynamic anatomy library combines with other data to generate dynamically filled in and fillable forms with relevant visualizations, codes, translations, and data. Dynamic forms that contain anatomy data are processed through a form processing engine for detection, categorization, encoding, translation, and labeling of the anatomy and non-anatomy data, and those outputs then process through a billing code engine, record generation engine, and image and visualization labeling engine. A record retrieval engine applies neural networks, computer vision, and artificial intelligence to re-create, analyze, categorize, and serve back record defined data to complete the loop.

A delivery arm assembly of a medical system includes a head having an end arranged to face a reference plane and a multistage slide mechanism coupled to the head. The multistage slide mechanism includes a long-range slide mechanism configured to move the head in a direction toward the reference plane and a short-range slide mechanism coupled with the long-range slide mechanism. The short-range slide mechanism is configured to stop further movement of the head in the direction toward the reference plane in response to a resistive force against movement of the head toward the reference plane.

A system for tracking the position of a surgical tool manipulated by a surgical robotic system, to determine that the tool is correctly positioned and orientated. Miniature 3-D tracking cameras are mounted on the end effector of the robotic system, one viewing markers on the surgical tool, and the other markers attached to the anatomy part being operated on. The initial spatial position and orientation of the surgical tool on the surface of the anatomy part is measured, and the progress of the surgical tool into the anatomic body part is tracked using one of the miniature cameras. The cameras or sensors are close to the surgical region of interest, and all the mechanical and sensor elements necessary for the system operation are mounted within the realm of the robot. The system thus avoids interruption of communication between a remotely positioned navigation camera and the robot or patient.
