A medical supporting arm according to the present disclosure includes a supporting arm and a calculation unit. The supporting arm supports an oblique-viewing endoscope. The calculation unit calculates a rotation angle of the oblique-viewing endoscope around an axis in a longitudinal direction, and an insertion amount of the oblique-viewing endoscope into a human body on the basis of a first expression that defines coordinates of a subject in a coordinate system in which an insertion opening allowing the oblique-viewing endo scope to be inserted into the human body serves as an origin, and a second expression that defines the coordinates of the subject positioned in an optical axis direction of an objective lens disposed at a distal end of the oblique-viewing endoscope in a coordinate system in which the distal end of the oblique-viewing endoscope serves as an origin.

The technology disclosed herein is directed to a medical manipulator system having a medical device. The medical device such as endoscope or other surgical instrument includes an elongated insertion portion. A holder assembly includes an articulated arm carrying the medical device that is attached thereto and is actuated following movement of the medical device and holds the medical device in a stationary state at a desired position. A position/attitude detection unit detects positions and attitudes of the elongated insertion portion in plurality states into which the medical device is caused to swing about a constraint point. A constraint point estimation unit estimates a position of the constraint point based on the positions and attitudes of the insertion portion as detected by the position/attitude detection unit.

There is provided a system for cardiac electromagnetic/magnetic catheterization for diagnosing and treating blood vessels of a patient. The system having at least one electromagnetic intraluminal capsule able to force its way through a narrowing blood vessel, the capsule carrying a camera allowing visualization of blood vessels of a patient. There is a portable electromagnetic tip, where the tip pulls the electromagnetic capsule by electromagnetic force, and when the magnetic tip moves along a body of a patient and pulls the intraluminal electromagnetic capsule along with it towards a narrowing blood vessel visualized by the camera, so that the capsule then treats the narrowing site and clears the blood vessel from coronary plaque. In addition working capsule can replace diseased valve in any cardiac position for either temporary or permanent needs.

Provided herein are systems, methods, and media capable of determining estimated force applied on a target tissue region to enable tactile feedback during interaction with said target tissue region.

A multifunctional catheter includes a catheter main body (1) and a distal tube (2) that are in a multi-channel structure. The distal tube (2) includes a soft end (21) at a proximal end and a functional end (22) at a distal end; a working channel (3) and a lens channel (6) are provided in the catheter main body (1) and the soft end (21), and the functional end (22) is also provided with a through hole communicating with the lens channel (6); the lens channel (6) is of a circular tubular-cavity structure extending along the catheter main body (1) and the soft end (21); and a plurality of accommodating slots (61) are provided on an inner wall of the lens channel (6) to accommodate a photosensitive chip in a lens assembly by the plurality of accommodating slots (61).

A number of improvements are provided relating to computer aided surgery utilizing an on tool tracking system. The various improvements relate generally to both the methods used during computer aided surgery and the devices used during such procedures. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled using the OTT device. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure including the rate of and type of data processed depending upon a CAS mode.

Disclosed herein are safety devices that are positioned on the end of a fiberoptic cable, such as those used in surgical procedures, to prevent patients and other objects from the risk of burn from light or heat emitted from the end of the cable when not connected to an optical instrument. The disclosed safety devices can be added to the ends of existing cables and/or can be included at the end of cables during manufacture. In some embodiments, the safety device replaces an existing connector at the end of a cable, and in some embodiments the safety device is added in addition to a connector at the end of the cable. In some embodiments, a slit end cover is included over an open end of an adaptor that is mounted on a distal connector of a fiberoptic cable.

A measuring device and methods of use for measuring a section of a bowel of a patient. The measuring device includes a tubular section having a longitudinal axis and at least one wing normally projecting outward transverse to the longitudinal axis. The tubular section is configured for mounting on a conventional or robotic laparoscopic grasper adjacent the grasper's movable jaws. The at least one wing is are pivotable to a closed position so that grasper with the measuring device mounted thereon can be inserted through a conventional trocar, whereupon the at least one wing projects outward transversely to the longitudinal axis. The at least one wing is of a predetermined length to serve as a measurement tool enabling a surgeon to measure off a desired length of the bowel.

Provided herein is a catheter assembly including an imaging device for identifying an anatomical structure. The catheter assembly includes a patient cannula configured to be drawn along a catheter or guide wire; a transseptal puncture catheter at least partially enclosed within the patient cannula; and an imaging catheter. The imaging catheter includes a transducer configured to emit an energy beam capable of reflecting from an anatomical structure and to detect energy reflected from the structure. The catheter assembly also includes a transmitter for conveying a signal representative of the detected energy from the transducer to a signal processor for obtaining information about the structure. An imagining system and a method for identifying a predetermined transseptal puncture location on an atrial septum are also provided herein.

A multifunctional camera system having a bendable arm configured to be inserted into the thoracic cavity of a patient and camera head at a distal end of the bendable arm. The camera head has a high definition video camera and a light source. The camera head has a view adjustment mechanism for changing a view angle of the camera without changing the position of the camera head. A controller controls the view adjustment mechanism under command of a surgeon.
