A medical robotic system that includes a robotically controlled surgical instrument. The system includes a constraint controller that constrains the movement of the instrument based on a predetermined parameter. The parameter may be a surgical space, wherein the instrument cannot be moved into, or alternatively cannot be moved out of, the space. The surgically constrained spaced may be defined through a telestrator screen that allows a surgeon to point and click the boundaries of the space.

The present invention relates to a medical robot system capable of effectively removing a calcified thrombus in a blood vessel. The present invention proposes a new guide-wired helical microrobot for mechanical thrombectomy applied to a calcified thrombus. Also, the present invention proposes an electromagnetic navigation system (ENS) which uses a high frequency operation that is based on a resonant effect in order to enhance the boring force of a microrobot. The microrobot system of the present invention can precisely tunnel through a blood vessel blockage site by means of the electromagnetic navigation system without damaging blood vessel walls. The microrobot system of the present invention has a wide range of applications including not only for thrombosis, but also thromboangiitis obliterans caused by vasoocclusion, cerebral infarction, strokes, angina or myocardial infarction, peripheral artery occlusive disease, or atherosclerosis, etc.

Flexible elongate devices and methods include an articulable body portion and a control structure attached with one or more pull wires that control articulation of the articulable body portion. The control structure includes a metallic material that defines a sealing surface functionalized by a primer. A polymer material disposed onto the sealing surface of the control structure creates a seal between the control structure and polymer material. Flexible elongate devices and methods also include a control structure and a pull wire configured to control articulation of the flexible elongate device. The control structure includes a plurality of control segments stacked along a longitudinal axis, where each of the control segments define a pull wire aperture, where pull wire apertures of adjacent control segments are offset relative to one another, such that a portion of the pull wire extending through the pull wire apertures has a non-linear shape.

A method for remote intervention for a subject includes acquiring an image of a region of interest of the subject using an interventional device positioned on the subject and an image acquisition system. The region of interest includes a target structure and the subject is located at a first site. The method further includes analyzing the acquired image using an image analysis module to identify and label the target structure in the region of interest and transmitting the labelled image from the first site to a second site for expert review. The second site is remote from the first site. The method further includes receiving a command signal at the first site from the second site where the command signal is generated based on the expert review of the labelled image and configured to control an action of the interventional device. In some embodiments, the method may further include analyzing the acquired image to determine a pathway to the vessel that avoids critical structures.

A robotic arm according to various implementations includes: a tool driver configured to hold a surgical tool; a first section comprising a first end coupled to a base, a second end distal from first end; a first link that includes a motor configured to rotate at least a portion of the first section around a pitch axis; a second link coupled to the first link, the second link including a motor configured to rotate at least a portion of the first section around a roll axis; and a second section comprising: a first end coupled to the second end of the first section, a second end distal from the first end, a first link that includes a motor configured to rotate at least a portion of the second section around a roll axis, a second link coupled to the first link.

The present invention relates to a visualization system disposed in a human body, including, a nanobot configured to be disposed within the human body, the nanobot having at least one embedded biosensor, the biosensor which operates in real-time to continuously obtain data from within the human body; a visualization device configured to be integrated and/or embedded within the nanobot to provide real-time visualization data in the human body; a transmitter/receiver disposed on the nanobot which transmits data from the nanobot to an external transmitter/receiver, the transmitted data including the data from the biosensor and the data from the visualization device; and a processor configured to receive the data from the external transmitter/receiver of the nanobot and analyze the visualization data to determine the anatomic localization of the nanobot at a specific anatomic position within the human body.

The present invention provides a robotic locomotive device (1) that is capable of driving itself forwards and backwards, anchoring and steering itself whilst inside a tubular structure (200), for example, the human colon, or any structure comprising two opposing walls (202, 204). In this respect, the device is made up of two or three segments (102, 104, 106) covered in an elastic material and driven by an internal actuating mechanism. All of the segments (102, 104, 106) have a concertina configuration that enable a shortening and lengthening motion. As well as contracting and extending in length, at least one of the end segments (102, 106) is capable of bending at an angle away from the longitudinal axis such that it becomes wedged or jammed between the walls (202, 204) of the tubular structure (200). That is, the end segments (102, 106) are capable of both a bending action and a contracting and extending action. The device (1) moves by alternately jamming a segment (102, 104, 106) between the walls (202, 204) of the tubular structure (200), and then contracting or extending the segments (102, 104, 106) to inch the device (1) forward with a more effective locomotive action. As such, the present invention provides a simplified design that is more robust to harsh or unclean environments, whilst still maintaining the level of performance required from such a device.
