Technical Field

The invention relates to the technical field of medical instruments, in particular to a tongue pressing clamp matched with pharyngeal indirect laryngoscopy.

Background

Indirect laryngoscopy is the most common and simple pharyngeal examination used in otolaryngological head and neck surgery outpatients. During examination, a light source is provided by an otolaryngological comprehensive treatment table, an examiner wears a frontal mirror, the patient sits up, slightly leans forward, opens the mouth, stretches the tongue and breathes by the mouth, the examiner wraps the front end of the tongue of the patient by using a piece of sterile gauze, the tongue is lightly fixed outside the incisors by using a thumb and a middle finger, and the index finger is pressed against the upper teeth. The right hand held indirect laryngoscope enters along the tongue back of the patient, the mirror surface is parallel to the tongue back but is not contacted with the tongue back, when the back of the endoscope reaches the uvula, the mirror surface is rotated to 45 degrees, the back of the endoscope is lightly used for pushing and pressing the root part of the uvula backwards and upwards, the tongue root, the tonsil, the epiglottis valley, the rear wall of the laryngopharynx, the side wall of the laryngopharynx and the free edge of the surface of the epiglottis are observed, and the arytenoid cartilage and the pear-shaped fossa at the two sides can be seen by slightly moving the mirror surface forwards and. Order the patient to make a long 'rely' sound to lift the epiglottis, and at the moment, the epiglottis laryngeal surface, aryepiglottic folds, arytenoid spaces, ventricular zona and vocal cords and the closing condition thereof can be seen; during indirect laryngoscope examination, the back of the tongue of a patient is often highly arched to influence pharyngeal cavity exposure, at the moment, the examinee needs to pull the tongue by himself, the examinee holds the indirect laryngoscope by the left hand, objects such as a right-hand epiglottis drag hook or a bent larynx dropper are held to pull up the epiglottis, the laryngeal cavity is exposed, when foreign matters or biopsy are taken under the indirect laryngoscope, the examinee also needs to pull the tongue by himself, the examinee holds the indirect laryngoscope by the left hand, and foreign matter forceps or biopsy forceps are held by the right hand.

At present, in clinical indirect laryngoscopy, a comprehensive treatment table of an otolaryngological department is matched with a frontal mirror to provide a light source, and meanwhile, a testee or a tested person can not ensure sufficient exposure of a pharyngeal cavity even if a sterile gauze is used for pulling a tongue for a long time, so that the inconvenience of the testee is caused, and the test result is influenced.
