Electrodes for use in electroencephalographic recording, including consciousness and seizure monitoring applications, have novel features that speed, facilitate or enforce proper placement of the electrodes, including aligning tabs and arrowed aligning juts, color coding, and an insulating bridge between reference and ground electrodes which ensures a safe application distance between the conductive regions of the two electrodes in the event of cardiac defibrillation or to prevent shorting between the adjacent electrodes by preventing the conductive path to be shared. A method of using a set of four such electrodes is also disclosed.

Described herein is a portable electrocardiograph, suitable for being hung round the neck of a patient and comprising a central body, a plurality of connectors and an electronic unit. Each one of the connectors is suitable for being associated to a respective electrode applied on the chest of the patient for detecting respective electric signals. Each one of the connectors is suitable for receiving the electric signals detected by the respective electrode and for transmitting the electric signals to the electronic unit. The central body comprises a rear surface, facing the patient when the electrocardiograph is in use. At least one of the connectors is mounted in a fixed manner on the rear surface of the central body. Each one of the other connectors is connected to the central body by means of a respective wire which can be wound and unwound. The central body comprises winding/unwinding means suitable for allowing each wire to be unwound independently from the other wires and for allowing each wire to be wound. The electronic unit is configured for receiving the signals from the connectors and for transmitting them to an electronic device external to the electrocardiograph. The invention also relates to an assembly comprising the electrocardiograph and the external electronic device.

A method of planning path for a surgical instrument is provided for use during a surgical procedure. The method includes identifying a treatment target in images of a patient to be treated during a surgical procedure, determining dimensions of the patient, a surgical instrument, and an external obstruction, and determining a path to guide the surgical instrument to the treatment target during the surgical procedure. The surgical instrument is configured to be used during the surgical procedure. The external obstruction is an object external to the patient's body that interferes with one or more potential paths of the surgical instrument. The path is determined such that the surgical instrument avoids the external obstruction based on the determined dimensions of the surgical instrument and the determined dimensions of the external obstruction.
