The present invention relates to a wireless capsule endoscope and a power supply control method thereof. The method includes controlling the power supply of the capsule endoscope wirelessly and automatically adjusting power consumption of the power supply in the capsule endoscope. The wireless capsule endoscope includes a capsule casing, a light generator arranged at outside of the capsule casing, an opto-electronic switching starter arranged in the capsule casing, a power supply, a control module, a posture sensor, an illumination unit, an image processing device and a radio frequency transmission unit. The power supply being driven by the light generator in the present invention can effectively solve the incompatible problem between a traditional magnetic switch and a magnetic control device. Meanwhile, the control module and the posture detector enable the power supply to be in different working status under different states, which can prolong the service life of the power supply of the capsule endoscope.

A light source illumination unit has operation modes including at least a normal electric power mode to operate with first electric power consumption, and a low electric power mode to operate with second electric power consumption lower than the first electric power consumption. A controller selects at least one of the operation modes in accordance with a use schedule, and controls the light source illumination unit in accordance with the selected operation mode.

The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

An endoscopic system includes an endoscope that obtains image information inside a subject; a first recording medium into which the image information obtained from the endoscope is written; a second recording medium that has a table in which a recording condition for writing the image information obtained from the endoscope into the first recording medium has been recorded; and a controller that obtains, on the basis of an operation time period obtained from the endoscope, a recording condition associated with the obtained operation time period from among the plurality of recording conditions recorded in the table that the second recording medium has, and records the image information in the first recording medium under the recording condition.

An endoscope system capable of automatically turning on/off a light source during a surgical procedure is disclosed. This endoscope system includes: an endoscope module; a light source module coupled to the endoscope module; and a light-source control module. Moreover, the light-source control module controls an ON/OFF state of the light source by: (1) receiving real-time video images captured by the endoscope module; (2) processing the real-time video images to determine whether the endoscope module is inserted into a patient's body or is outside of the patient's body; and (3) in response to determining the endoscope module being outside of the patient's body while the light source is turned on, generating a control signal to immediately turn off the light source to the endoscope module, thereby ensuring safety of people in the operating room and preventing sensitive information in the operating room from being captured by the endoscope module.

A sensor including electrodes, a control module and a physical layer module. The electrodes are configured to (i) attach to a patient, and (ii) receive a first electromyographic signal from the patient. The control module is connected to the electrodes. The control module is configured to (i) detect the first electromyographic signal, and (ii) generate a first voltage signal. The physical layer module is configured to: receive a payload request from a console interface module or a nerve integrity monitoring device; and based on the payload request, (i) upconvert the first voltage signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the sensor to the console interface module or the nerve integrity monitoring device.

A nerve integrity monitoring device includes a control module and a physical layer module. The control module is configured to generate a payload request. The payload request (i) requests a data payload from a sensor in a wireless nerve integrity monitoring network, and (ii) indicates whether a stimulation probe device is to generate a stimulation pulse. The physical layer module is configured to (i) wirelessly transmit the payload request to the sensor and the stimulation probe device, or (ii) transmit the payload request to a console interface module. The physical layer module is also configured to, in response to the payload request, (i) receive the data payload from the sensor, and (ii) receive stimulation pulse information from the stimulation probe device. The data payload includes data corresponding to an evoked response of a patient. The evoked response is generated based on the stimulation pulse.
