Description

Throat expansion and foreign matter taking device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a laryngeal dilation and foreign body extraction device.

Background

Foreign matter card larynx is when getting into the esophagus, the card is in the throat position, foreign matter card larynx phenomenon takes place on children mostly, but also do not get rid of and can not take place on one's body adult, the foreign matter card larynx is light then leads to children to breathe not smooth, then oppress the trachea and lead to children to suffocate and die, or meet sharp-pointed thing card larynx and arouse patient's throat infection, bacterium or inflammation diffusion are easily aroused fever etc. and are accompanied the symptom to the trachea, the patient must come the foreign matter when the foreign matter card larynx, otherwise can influence patient's daily diet, or harm patient's self healthy.

Most of the existing devices aiming at the foreign body throat blockage adopt tools such as tweezers or operation lead to be taken out from the esophagus, if the patients encounter sharp foreign bodies, the throat of the patients is easily scratched in the taking-out process, causes secondary wound to the patient, if the device is combined with the expansion device, the safety of taking out the foreign body is improved, the conventional forceps are not suitable for all shapes and materials, and the absence of a fixing device for taking out foreign matters requires a doctor with higher technique, so that the operation process is longer, the treatment time is delayed, if the throat is locally expanded, the stress area is too small, and the throat is fragile, the trachea or mucosa in the throat is easily damaged and not easy to recover, the incidence rate of the accidents of the patient treatment is increased, moreover, if local dilation is adopted, for example, foreign bodies stuck in the throat are provided with obvious tips or raised parts, and the throat is easily scratched when the foreign bodies are taken out.
