An endoscope apparatus includes an identification unit provided in each of a plurality of optical adaptors, an MMA connected in parallel to the identification unit, an MMA drive circuit that is provided in a main body portion and applies a drive signal for driving the MMA through a pair of conductive wires, a sine-wave generation circuit that is provided in the main body portion and applies an alternating signal to the identification unit through a pair of conductive wires in a state where any one of the plurality of optical adaptors is mounted at a distal end portion, and CPU that is provided in the main body portion and measures an input impedance of the pair of conductive wires at a frequency of the alternating current signal to perform individual identification of the optical adaptor mounted at the distal end portion based on a measurement result.

The invention relates to medical devices for carrying out internal examination, such as laryngoscopes. The laryngoscope is provided with a camera element within a channel inside the blade.

A cart or man-portable system and method for performing endoscopic procedures is provided. A portable display device, such as a laptop computer, is coupled to a handle comprising a miniature camera and fiber optic illumination subsystem. A sterile disposable portion is fitted over the illumination subsystem and inserted into a target area on a patient. Images of the target area are conveyed from the camera to the display device while an endoscopic procedure is performed, thus facilitating real-time diagnosis during the procedure.

A medical device may include an insertion portion longitudinally extending between a proximal end and a distal end. The insertion portion may define a channel extending therethrough. The medical device may further include a handle coupled to the proximal end of the insertion portion. The handle may further include an irrigation port in fluid communication with the channel and coupled to a source of irrigation fluid. Additionally, the handle may include an actuator and a pressurizer. Manipulation of the actuator may be configured to actuate the pressurizer to urge irrigation fluid distally through the channel.

A surgical imaging system including a surgical imaging device including identification information; a holding arm that holds and controls a position of the imaging device; a user interface configured to provide non-contact operation of the holding arm; and processing circuitry configured to control the holding arm according to the identification information and an output of the user interface.

An information processing system includes a server, a client, and a tag reader. The server and the client are connected via a network. The tag reader includes: a reading unit that reads an endoscope ID assigned to a single-use endoscope; and a transmitting unit that transmits the endoscope ID read by the reading unit to the client. The client includes: a receiving unit that receives the endoscope ID transmitted from the transmitting unit; and a use information transmitting unit that transmits use information on the endoscope based on the endoscope ID received by the receiving unit. The server includes a use information acquisition unit that acquires the use information transmitted from the use information transmitting unit.

A medical navigation system is provided for controlling medical equipment during a medical procedure. The medical navigation system includes a passive radio frequency identification (RFID) tag, an RFID sensor for detecting the passive RFID tag, a controller coupled to the RFID sensor, and a robotic arm having an end effector and controlled by the controller. The RFID sensor provides a signal to the controller indicating presence of an activated passive RFID tag. The passive RFID tag has an antenna, an RFID circuit, and a switching device coupled to the RFID circuit for activating the passive RFID tag. The passive RFID tag is used to control a payload attached to the end effector.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor is configured to execute the instructions to receive, from a sensor of a surgical instrument, environmental condition information associated with the surgical instrument and detected by the sensor while the surgical instrument is disconnected from an external power source, the surgical instrument including circuitry configured to be powered and operate only while the surgical instrument is connected to the external power source, determine, based on the environmental condition information, an operational condition of the surgical instrument, and provide a notification indicating the determined operational condition of the surgical instrument.

A visualized medical system with a cavity expanding device includes a cavity expanding mechanism and an observation mechanism. The cavity expanding mechanism includes an expanding end arranged at a front end of the operating mechanism and configured to expand a cavity at the front end of the observation mechanism to expand a field of view of the observation mechanism. The observation mechanism includes a lighting module, a lens module, a signal processing module, and a housing. An image and a video observed in the lens module in a light field of the lighting module are processed by the signal processing module, and then outputted to a display system by a circuit system for displaying. The visualized medical system with a cavity expanding device can introduce a surgical instrument into a body from a sheath to perform various surgical operations such as biopsy sampling, electrocution, electrocoagulation, and ablation during observation.

A method for reconditioning an endoscope in a reconditioning apparatus, the method including: connecting an interior of the endoscope to a leakage tester of the reconditioning apparatus; supplying the interior with a fluid at a predefined pressure; carrying out a reconditioning process using a rinsing liquid; monitoring the pressure in the interior of the endoscope during the reconditioning process; and identifying the endoscope as defective if a profile of the pressure deviates from a predefined pressure profile; wherein the predefined pressure profile is determined according to process parameters of the reconditioning process.
