A medical observation apparatus includes: a camera configured to capture an object image of an observation target; a support configured to support the camera so as to be rotatable about a plurality of mutually-different shafts; a memory configured to store the position of the camera; a brake configured to switch between: a permission state for permitting the camera to rotate about at least one of the plurality of shafts; and a restriction state for restricting the rotation; and a controller configured to perform a reproduction process for switching the brake to the permission state, and thereafter switching the brake from the permission state to the restriction state when the support is operated according to an external force applied to the support by an operator and the camera is located at the position of the camera stored in the memory.

The present disclosure provides a treatment assistance apparatus, comprising: a base; a first joint of which one side is coupled to the base to relatively move; a first arm of which one end is rotatably coupled to the other side of the first joint; a second joint of which one side is rotatably coupled to the other end of the first arm; an adapter arm of which one end is coupled to a first adapter to relatively move, and the first adapter is rotatably coupled to the other side of the second joint; a first driving part disposed in the first joint and configured to rotate the first arm; a second driving part disposed in the second joint and configured to rotate the adapter arm; a pressure part configured to stop a relative motion of the first adapter; and a controller configured to control the first driving part, the second driving part and the pressure part.

A vaginal speculum which includes a fixed blade and a movable blade. The movable blade designed to be extended or retracted as required in order to adjust to the length of the vaginal canal of the patient undergoing surgery. A vaginal speculum is further designed with a blade angle mechanism and a blade pivoting mechanism which allows and controls the angle and rotation of the blades in relation to its base. Vacuum connection and a light can also be provided.

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

Systems and methods for delivery a medical device to a heart valve annulus are disclosed. A method of delivering a medical device to a heart valve annulus includes: (1) aligning a first imaging sensor such that a view of the first imaging sensor is along a primary plane of the heart valve annulus; (2) aligning a second imaging sensor such that a view of the second imaging sensor is along a longitudinal axis of the heart valve annulus; (3) attaching a delivery system holding the medical device to a delivery arm; (4) adjusting the delivery arm to set an angle of the delivery system perpendicular to the primary plane using images from the first imaging sensor; (5) adjusting the delivery arm to center the delivery device in the heart valve annulus using images from the second imaging sensor; and (6) deploying the medical device into the heart valve annulus.

A medical holding device includes: an arm configured by coupling a plurality of links to each other by joints, the arm having at least seven or more degrees of freedom by rotational operations on rotation axes, and being configured to support a medical instrument; and an arm controller configured to control an operation of the arm. The arm has six degrees of freedom realized by rotational operations of six passive rotation axes that passively rotate and one or more degrees of freedom realized by rotational operations of one or more active rotation axes that actively rotate, and the arm controller is configured to rotate the active rotation axis so as to avoid a predetermined state of a posture of the arm.

A medical observation control device and system include a memory that stores a parameter for a first imaging condition of an imager at a first time of capturing a first medical image and circuitry configured to correct for brightness differences between the first medical image captured at the first time and a second medical image captured at a second time. The circuitry is configured to restore the parameter for the first imaging condition as a second imaging condition for capturing the second medical image, control the imager so as to capture an image of an observation object under the second imaging condition as the second medical image, compare the first medical image with the second medical image, and correct brightness of at least one of brightness of the first medical image and brightness of the second medical image based on a comparison result.

A computer-implemented medical data processing method for controlling a geometric status of a mechatronic articulable arm. Current geometric status data is acquired describing a current geometric status of the mechatronic articulable arm defined by a set of current spatial relationship between connected elements of the mechatronic articulable arm. Changed geometric status data describing a changed geometric status of the mechatronic articulable arm defined by a set of changed spatial relationship between the connected elements is determined based on current device position data, the current geometric status data, changed device position data, and device definition data. Instruction data describing an instruction for changing the geometric status of the mechatronic articulable arm from the current geometric status to the changed geometric status is determined. The instruction describes changes from the current spatial relationship to the changed spatial relationship.
