System for guiding an instrument within a vascular network of a patient are disclosed. In some embodiments, the system receives a medical image from a medical imaging device and identifies a distal tip and a direction the instrument in the image. The system may then determine a waypoint for the distal tip of the instrument based at least in part on the position and direction of the distal tip of the instrument. The system may then generate a trajectory command for moving the instrument through the vascular network from the current position to the waypoint. The system may operate in a closed loop. The system may provide the trajectory command to a robotic medical system configured to move the instrument according to the command.

Provided is a multi-segment rotation robotic arm which contains a plurality of concatenated robotic arm segments which can rotate 360 degrees along an adjacent oblique section thereof. Any one of the concatenated robotic arm segments of the multi-segment rotation robotic arm can be arbitrarily concatenate in accordance with use requirements. When the concatenated robotic arm segments rotate relatively, they can rotate 360 degrees without affecting the electric supply, and can also reduce the volume increase by rotated joints. Therefore, the multi-segment rotation robotic arm of the present invention can effectively adapt to complex and tortuous spaces in the body cavity to reduce the possibility of expanding the opening of the minimally invasive surgery and causing damage to organs or tissues in the body cavity.

The present invention relates to a micro robot driving apparatus which can increase the intensity of magnetic field generation in a driving area of a micro robot by attaching a magnetic shield unit to an electromagnetic drive coil unit for driving the micro robot, or locally focus a magnetic field through the combination of two electromagnets, and a system using the same. According to the present invention, there is an effect that driving the micro robot injected into the body may be controlled by increasing a magnetic field generation intensity in the region of interest or focusing the magnetic field.

Apparatus and methods are described including acquiring 3D image data of a targeted skeletal portion within a body of a subject, and a 2D radiographic image of the targeted skeletal portion. A machine-learning engine is used to generate machine-learning data based on (i) the 3D image data of the targeted skeletal portion, (ii) a database of 2D projection images generated from the 3D image data, and (iii) respective values of one or more viewing parameters corresponding to each 2D projection image. A computer processor receives the machine-learning data, receives the 2D radiographic image of the targeted skeletal portion, and registers the 2D radiographic image to the 3D image data by using the machine-learning data to find a 2D projection from the 3D image data that matches the 2D radiographic image of the targeted skeletal portion. Other applications are also described.

A surgical system includes a drive unit on a support. The drive unit includes motors or other actuators and a plurality of output elements arranged such that operation of each drive unit linearly translates a corresponding one of the output elements. A surgical device has an input subsystem carried at the proximal end of the shaft. The input subsystem includes linearly translatable input elements or pistons. The input and output elements are positioned such that operation of an actuator linearly translates an output element, causing linear translation of a corresponding input element. The input elements deliver linear motion to a rotary conversion system which converts the linear motion to rotary motion and delivers the rotary motion to a shaft of the surgical device, causing axial rolling of the surgical device or its distal end effector. A sterile drape is positionable between the input elements and the output elements.
