The present application relates to a motion control method and system for a mechanical arm and surgical system, the terminal end of the mechanical arm is adapted to carry an effector, the method includes steps of: receiving a first control command from a first input device by a graphical user interface, wherein the first control command is configured to control the mechanical arm to move according to a first movement mode; receiving a second control command from the first input device or a second input device, wherein the second control command is configured to control the mechanical arm to enter a second movement mode; and receiving a third control command from the second input device, wherein the third control command is configured to control the effector to perform a predetermined movement, wherein the first input device and the second input device are separated from each other.

A system and method are provided for aligning a tool with a targeted axis in tissue to perform a medical procedure. medical plan is registered to the location of the tissue using a computer-assisted medical system, where the medical plan include a planned position for the targeted axis based on pre-procedure data. The tool is aligned with the planned position for the targeted axis using a computer- assisted medical system. The computer-assisted medical system includes a hand- held device having a handle and a working portion adjustable relative to the handle so as to orient the tool. A computing system is also provided comprising a tracking system and a control system for registering the medical plan to the location of the tissue, tracking the hand-held device relative to the tissue and the medical plan, and adjusting the working portion of the hand-held device relative to its handle.

A system for performing a surgical procedure includes a controller including a memory and a processor, the memory storing instructions, which when executed by the processor cause the processor to receive an image captured by a camera, generate a segmented image by applying a first threshold value to the image captured by the camera, identify a lumen within the segmented image, determine a centroid of the lumen within the segmented image, and align a portion of a surgical device operably coupled to the controller with the centroid of the lumen.

The present disclosure provides a system for enabling autonomous or semi-autonomous surgical operations. The system comprises: one or more processors that are individually or collectively configured to: process an image data stream comprising one or more images of a surgical site; fit a parametric model to a tissue surface identified in the one or more images; determine a direction for aligning a tool based in part on the parametric model; determine an optimal path for automatically moving the tool to perform a surgical procedure at the surgical site; and generate one or more control signals for controlling i) a movement of the tool based on the optimal path and ii) a tension force applied to the tissue by the tool during the surgical procedure.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

A system for ablating or monitoring a zone of the heart, includes a system to measure the heart electrical activity; a phased array for generating a beam of focussed ultrasound signals on a targeted zone of the heart; an imaging system determining an image of a transcostal wall projected in an image plane of the phased array by taking into consideration a position and direction of the phased array and making it possible to deactivate elements of the phased array in accordance with the position of the elements with regard to the position of the projected image of the transcostal wall; a positioning system to control the position of a focussed zone of a beam of focussed ultrasound signals on the targeted zone, a monitoring system to measure a temperature and tissue deformation in the targeted zone; and a device for measuring a level of cavitation in the targeted zone.

A system for assisting guiding an endovascular instrument in vascular structures of an anatomical region of interest of a patient. This system includes an imaging device for capturing three-dimensional images of parts of the body of a patient, a programmable device and a viewing unit. The imaging device captures partially superposed fluoroscopic images of the region, and the programmable device forms a first augmented image, representative of a complete panorama of bones of the region, and cooperates with the imaging device to obtain a second augmented image including a representation of the vascular structures of the region. The imaging device captures a current fluoroscopic image of a part of the region, and the programmable device registers the current fluoroscopic image with respect to the first augmented image and locates and displays, on the viewing unit, an image region corresponding to the current fluoroscopic image in the second augmented image.

Systems and methods are provided in which intraoperatively acquired surface data is employed to verify the correspondence of an intraoperatively selected spinal level with a spinal level that is pre-selected based on volumetric image data. Segmented surface data corresponding to the pre-selected spinal levels may be obtained from the volumetric image data, such that the segmented surface data corresponds to a spinal segment that is expected to be exposed and identified intraoperatively during the surgical procedure. The segmented surface data from the pre-selected spinal level, and adjacent segmented surface data from an adjacent spinal level that is adjacent to the pre-selected spinal level, is registered to the intraoperative surface data, and quality measures associated with the registration are obtained, thereby permitting an assessment or a determination of whether or not the pre-selected spinal surface (in the volumetric frame or reference) is likely to correspond to the intraoperatively selected spinal level.
