Description

Technical Field

[0001] The invention relates to an instrument for throat examination and minimally invasive surgery assistance. Background Art

[0002] Since the ear, nose and throat are deep and small cavities, special lighting devices and inspection instruments must be used for inspection. Commonly used ones include 100-watt inspection lamps with focusing lenses, forehead mirrors (concave reflectors that can focus light), otoscopes, pneumatic otoscopes, gun-shaped forceps, rolled cotton seeds, cerumen hooks, tongue depressors, anterior nasal mirrors, posterior nasal mirrors, indirect laryngoscopes, tuning forks, sprayers, etc. The general oropharyngeal inspection method is to use a tongue depressor to gently press the front 2 / 3 of the patient's tongue, check the tonsils, lingual palate arches, pharyngeal palate arches, posterior pharyngeal wall, etc., and observe the activity of the soft palate. The functional status of the Eustachian tube is closely related to the occurrence and prognosis of otitis media. In the case of middle ear diseases or sound transmission dysfunction, the patency of the Eustachian tube should be checked. There are many methods for this inspection, and the following are commonly used: ① Swallowing method and pinching nose pneumatic method (Valsalva method). When the examinee swallows or pinches his nose to blow air, the examiner can listen to the sound of air entering the tympanic cavity through the Eustachian tube through the stethoscope. There is an earplug head at each end of the tube, which can be inserted into the examinee's ear and the examinee's ear canal respectively. If the Eustachian tube is open, the examiner can hear the sound of the Eustachian tube opening from the stethoscope. ② The Polizzer method. First clear the nasal secretions, and then let the examinee hold a small amount of drinking water in his mouth. The examiner inserts the olive head of the Polizzer blowing ball into one of the anterior nostrils, and presses the other anterior nostril with the fingers of the other hand, so that the patient swallows water, and the soft palate will close the pharyngeal passage, making the nasopharynx closed; the examiner simultaneously pinches the Polizzer ball, the pressure in the nasopharynx increases, and the air will be forced to enter the tympanic cavity through the Eustachian tube, and the sound can be heard through the stethoscope. ③ The catheter method. After anesthetizing the surface of the nasal mucosa with a special Eustachian tube catheter, send its elbow along the nose to the nasopharynx. At the position equivalent to the posterior edge of the nasal septum, turn the catheter elbow downward and outward to insert it into the pharyngeal opening of the Eustachian tube, and use a balloon to press air in. The examiner can also monitor the airflow entering the Eustachian tube through the stethoscope. The pressure applied during the blowing of the Politzer method and the catheter method is relatively large. When the Eustachian tube is narrow, it can often be opened by the airflow. Through the stethoscope, you can hear the "chi chi" sound of the airflow squeezing through the narrow part. If you hear the sound of bubbles, it indicates that there may be tympanic effusion; if it is completely silent, it indicates that the Eustachian tube is blocked. The blowing of the Eustachian tube should be gentle to avoid iatrogenic damage. Therefore, the tympanic membrane and hearing should be checked before and after blowing to observe whether there are any changes. Then the current methods are too traditional, and there is no one that can improve this traditional method and lead to an instrument that is convenient for surgery or examination.
