A fiberoptic device that facilitates the performance of tracheotomies and a method for performing tracheotomies using that device. The device comprises a relatively short rigid tubular housing sealed at one end and connected at the other to a long tubular sheath. A bundle of optic fibers is contained in the sheath throughout its length. Light may be passed through the fibers and directed to a port near the sealed tip of the housing where it exits. The sheath has distance markings on its surface which enable a determination of the distance of the port to a point of observation within the markings. Also on the sheath is an alignment marking which enables the determination of the orientation of the port by observing the orientation of the alignment marking. To use the device there must first be an endotracheal tube in place in the patient. An incision is made in the anterior portion of the neck and tissues in the vicinity of the trachea exposed. The device is then inserted into the endotracheal tube to the extent that the distance markings with relation to an appropriate reference point, such as the end of the endotracheal tube, indicate that the port is at the desired position. Light is then passed through the bundle of optic fibers, is emitted from the port and is seen by the surgeon through the exposed tissues. The surgeon is thereby directed to the proper location to complete the tracheotomy.
