Embodiments of the present disclosure include a system for determining an error associated with an electrode disposed on a medical device. The system comprises a processor and a memory storing instructions on a non-transitory computer-readable medium. The instructions are executable by the processor to receive an electrode signal from the electrode disposed on the medical device. The instructions are further executable by the processor to receive a plurality of other electrode signals from a plurality of other electrodes disposed on the medical device. The instructions are further executable by the processor to determine that the electrode signal received from the electrode disposed on the medical device is an outlier in relation to the plurality of other electrode signals from the plurality of other electrodes disposed on the medical device, based on a comparison between the electrode signal and the plurality of other electrode signals.

A coefficient calculator calculates a correlation coefficient representing a correlation between a normal frame, which is imaged in a state in which normal light is applied to a subject, and a special frame, which is imaged in a state in which special light is applied to the subject; and a processing unit that applies image processing to the special frame so that a part in which the correlation coefficient is high and a part in which the correlation coefficient is low are displayed differently in the special frame. Further provided are: a first determination unit that calculates, for each pixel or each area of the normal frame, a first determination value representing a probability that a predetermined site is imaged; and a second determination unit that calculates, for each pixel or each area of the special frame, a second determination value representing a probability that a predetermined site is imaged.

A method of operating a surgical anchoring system can include inserting an outer sleeve of a surgical instrument at least partially into a first natural body lumen, the outer sleeve having a working channel. The method can include inserting a channel arm of the surgical instrument through the working channel of the outer sleeve and into a second natural body lumen. The channel arm has at least one first anchor member coupled thereto and a control actuator operatively coupled to the at least one first anchor member. The method can include expanding the at least one first anchor member from an unexpanded state to an expanded state to form an anchor point at a portion of the second natural body lumen. The method can include controlling, by the control actuator, a motion of the channel arm to selectively manipulate an organ associated with the first and second natural body lumens.

[Problem to be Solved] Provided are a medical display controlling apparatus and a display controlling method capable of enhancing convenience of medical providers.

[Solution] Provided is a medical display controlling apparatus including: a generating unit configured to generate a three-dimensional model of an observed object based on a right-eye medical captured image and a left-eye medical captured image taken by an imaging device configured to image the observed object; and a display controller configured to cause a display screen to display a combination of the three-dimensional model with a right-eye special light observation image and a left-eye special light observation image, or a combination of the three-dimensional model with biological information acquired from an external biological information acquiring apparatus.

A control section as a tissue identification device includes: an absorbance ratio calculating section configured to calculate the ratio of an absorbance indicated by a transmitted portion of first inspection light transmitted through biological tissue to an absorbance indicated by a transmitted portion of second inspection light transmitted through the biological tissue; and an identification information generating section configured to generate identification information indicative of the type or state of the biological tissue by determining within which of a plurality of preset numerical ranges the ratio falls.

In an imaging system, a differential signal transmission circuit is configured to output a first signal to a first signal line in an image output period and is configured to output a second signal to a second signal line in the image output period. The first signal and the second signal are included in a differential signal. A signal output circuit is configured to output a second clock signal to the first signal line in a blanking period different from the image output period and is configured to output a second control signal to the second signal line in the blanking period. In a PLL, connection between a charge pump and a loop filter is controlled on the basis of the second control signal output to the second signal line.

An object of the present invention is to provide an endoscopic examination information analysis apparatus and an endoscopic examination information analysis method capable of enabling a user to easily grasp a use status of an examination use article and an execution status of a procedure, and an endoscopic examination information input support system capable of efficiently supporting an input of examination information. In accordance with an endoscopic examination information analysis apparatus according to a first aspect of the present invention, since an examination database is updated based on examination information generated whenever an examination is executed, use information of an examination use article is calculated based on a use history of the examination use article for a selected examination item, execution information of a procedure is calculated based on execution history of the procedure, and the calculated use information and execution information are displayed on a display device for each examination use article or procedure, a user can easily grasp the use status of the examination use article and the execution status of the procedure.

A method for mapping an internal structure of a patient with an elongate body is provided. The method includes detecting, at a plurality of instances, contact between a distal portion of an elongate body and an internal structure of the patient; determining a plurality of geometric configurations of the distal portion, the plurality of geometric configurations corresponding to the plurality of instances of contact between the distal portion and the internal structure; determining a plurality of positions of the distal portion, the plurality of positions corresponding to the plurality of geometric configurations; and generating a map of the internal structure based on the plurality of positions of the distal portion.

An optical module for endoscope includes an optical element including an external terminal, a housing in which an insertion hole into which an optical fiber is inserted is present and has a bottom and a bottom surface made of a transparent material, and a sealing plate that is bonded to the housing. The optical element is stored in an upper recess of the housing, the external terminal and a bonding electrode are connected using a bonding wire, and a wire recess in which a part of the bonding wire is stored is present in a bottom surface of the upper recess.

An endoscope apparatus includes a connection interface to which an endoscope is connected, a communication interface that transmits/receives signals to/from an external apparatus, a computation device that determines whether or not the endoscope is connected to the connection interface, switches a processing state of the endoscope apparatus from an inspection state to a non-inspection state or from a non-inspection state to an inspection state, and performs control to switch the processing state from the inspection state to the non-inspection state upon acquiring an instruction signal for instructing switching of the processing state from the inspection state to the non-inspection state from the external apparatus via the communication interface, when it is determined that the endoscope is not connected to the connection interface.
