Provided is a medical display control device including a display control unit that causes a first captured medical image and a second captured medical image to be simultaneously displayed, the first captured medical image having been captured in an imaging device in a first imaging mode where imaging is performed with special light, the second captured medical image having been captured in the imaging device in a second imaging mode different from the first imaging mode before the first captured medical image.

Medical display control device, medical observation device, display control method, and medical observation system

There is provided a medical stereoscopic observation device, including: an acquisition section that acquires a first signal associated with a first imaging section and a second signal associated with a second imaging section via mutually different transmission channels; and a switching section that switches a signal to use for a certain control between the first signal and the second signal, in accordance with a state of the transmission channel for transmitting the first signal.

Medical stereoscopic observation device, medical stereoscopic observation method, program, and medical stereoscopic observation system

There is provided a wearable medical observation apparatus used by being worn on a head of a user, including: a first observation section having a configuration enabling a first observation of an observation target through an optical system including at least an objective lens; a second observation section having a configuration enabling a second observation of an observation target by a first medical observation image in which the observation target is imaged by a first imaging device; and a control section configured to control an observation state of the observation target.

Medical observation apparatus

A medical three-dimensional observation apparatus includes at least a pair of imaging units, a three-dimensional image processing unit, a calculating unit, and an index superimposing unit. The imaging units image a .specimen from different viewpoints. The three-dimensional image processing unit displays a three-dimensional image of the specimen on a display in accordance with images of the specimen. The calculating unit calculates a region of a three-dimensional reproduction space of the display in which the three-dimensional image of the specimen is to be reproduced. The index superimposing unit superimposes an annotation image on a depth position corresponding to the region in which the three-dimensional image is reproduced.

Medical three-dimensional observation apparatus

An apparatus for holding a medical device has an arm unit equipped with, for example, a polyarticular arm, which holds the medical device such as endoscope movably in the space. Additionally to a determination unit and a controller, the holding apparatus has an operation unit equipped with a plurality of operation members with which an operator's operation causes the arm unit to be moved spatially. The determination unit determines whether or not operator's operations at the plurality of operation members corresponds to an improper state deviating from a properly operated state in which at least two predetermined operation members have been operated within a predetermined period of time which is set to measure simultaneity for operations. If it is determined that the operation is in the improper state, the controller prohibits the arm unit from moving. As long as the operation is proper, the arm unit can be moved.

Method and apparatus for removably holding medical device

There is disclosed an operation microscope in which an observing and displaying system of an operating instrument are selected, and an endoscope image for observing a dead angle of the microscope and a navigation image are selectively displayed in a microscope observation field, so that a tomographic image, three-dimensionally constructed image, and the like can be selectively displayed in a display screen in accordance with a treatment position displayed in a monitor or an observation position of the operation microscope.

Operation microscope

A plurality of handpieces used to perform an operation is connected to a main operation apparatus, which generates a driving signal, through connectors formed on the main apparatus. When an operator holds a handpiece he/she wants to use, an output line over which the driving signal is transmitted is routed to the held handpiece owing to an output of a sensor that detects a change in capacitance stemming from the hold. The operator therefore need not manually set a mode in which the driving signal is applied to the handpiece he/she wants to use. Moreover, a port number assigned to a port to which the output line is routed is indicated on a display device. The operator can readily identify the usable handpiece.

Surgical operation system

A light-source device includes a lamp unit having a light-source lamp and a device housing which is provided with a lamp-unit container for containing the lamp unit in a removable manner. The device housing includes a CPU for measuring the illumination time of the light-source lamp and an antenna for sending the illumination time measured by the CPU to the lamp unit. The lamp unit includes an RFID tag which is fixed thereto. The RFID tag is provided with an antenna for receiving the illumination time information sent from the antenna of the housing and a rewritable memory for storing the illumination time information received by the antenna of the tag.

Light source device

Provided is a surgical observational system capable of effectively displaying, in the field of an operating microscope, a real-time image obtained by means of an ultrasonic probe, for example, and a slice image obtained by a preoperative diagnosis on the location of the distal end portion of the probe or a three-dimensional image of an affected region, in association with an actual observational image obtained by means of the microscope. The surgical operation observational system is provided with two monitors in the operating microscope for the observation of the affected region to be operated. Images on the two monitors are alternatively superposed on the optical path of the operating microscope.

Surgical microscopic system

A surgical microscope apparatus incorporating a frame portion placed on a floor, a microscope body for stereoscopically observing a portion to be operated, an arm portion supported by the frame portion and arranged to suspend the microscope body, and an endoscope for observing a blind spot for a stereoscopic observation field of view. The frame portion has a light source unit for generating light for illuminating a portion observed with the endoscope and a camera control unit for processing an observed image of an observed portion obtained by the endoscope. A light guide fiber extending from the light source unit to the microscope body and capable of supplying light to the endoscope, and a camera cable for transmitting the image observed with the endoscope to the camera control unit extend in the arm portion. The microscope body is provided with an end of the light guide fiber for connecting the endoscope and a camera head connected to the camera cable.

Surgical microscope apparatus

A surgical microscope includes an illumination optical system for illuminating a microscope visual field, an observation optical system which has an eyepiece lens and an imaging lens and allows observation of a first image of an observation target by guiding reflected light from the observation target irradiated with illumination light to the eyepiece lens from the illumination optical system, an image projection optical system for projecting a second image as image information within a portion of the microscope visual field, and visual field adjusting mechanism which has a field stop placed at an imaging position of the imaging lens and having a changeable stop shape and adjusts an area of the microscope visual field by changing the stop shape of the field stop in accordance with a projection state of the second image with respect to the microscope visual field.
