Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pharyngoscope. Background Art

[0002] The pharyngoscope is used to observe the pathological conditions of the throat. In clinical anesthesia and emergency medicine, it is often necessary to intubate the patient for artificial respiration and anesthesia. During tracheal intubation, first insert the anesthesia pharyngoscope into the patient's mouth, gradually go deeper, press the tongue to the bottom of the mouth to show the pharyngeal cavity, and after seeing the epiglottis clearly, place the tip of the lens in the epiglottic valley between the epiglottis and the root of the tongue, move the lens upward to make the epiglottis as close to the root of the tongue as possible, revealing the glottis and pharyngeal cavity originally blocked by the epiglottis, then aim the tracheal tube at the glottis and insert it into the trachea, and remove the pharyngoscope.

[0003] The patent with the announcement number CN219680591 U discloses a clinical laryngoscope for anesthesia, including a handle, one end of which is equipped with a camera and an LED light source, and the other end of which is equipped with a display screen. The user of the utility model can rotate the fixed shell, and the rotating column rotates synchronously along the inner part of the built-in groove while the fixed shell rotates, so that the display screen can be adjusted in multiple directions, and the display screen can be rotated, extended and contracted, so that different users can adjust the display screen to a comfortable observation position for themselves.

[0004] The handle of the above-mentioned pharyngoscope cannot rotate relative to the pharyngoscope. When in use, due to the different lying positions and head tilt degrees of the patients, the fixed-angle pharyngoscope will have a hard top and rub against the patient's oral cavity wall during insertion, making the insertion process uncomfortable and affecting the patient's treatment experience. At the same time, the display screen can only be adjusted in height and rotated laterally, but the angle of the display screen cannot be adjusted, so that the display screen cannot face the medical staff's line of sight, which makes it inconvenient for medical staff to observe the patient's throat condition well, and the practicality is poor.
