Description

General anesthesia mouth gag for oral operation

Technical Field

The utility model relates to an anesthesia opening field specifically is oral operation general anesthesia mouth gag.

Background

During general anesthesia of a patient, various reflexes of the patient disappear and respiratory functions are inhibited, except that the patient can still breathe by himself under the strict monitoring of an anaesthetist in some painless examination or superficial operation anesthesia, most general anaesthetized patients need artificial assisted respiration, the artificial assisted respiration is of various types, the highest clinical utilization rate is oral tracheal intubation, in the process, the anaesthetist inserts a plastic tube with small fingers and thickness into the trachea from the oral cavity by using an intubation tool after consciousness of the patient disappears, in the operation process, the tracheal catheter is used for conveying oxygen to the patient, and after the operation is finished, when various indexes of the patient are qualified and the respiratory functions are recovered, the anaesthetist pulls out the catheter for the patient. The fixed pipe mode of current oral cavity general anesthesia operation, adopt the adhesive tape to paste more, often change the pipe position because of the operation needs in the operation, for example move the pipe to another side mouth angle by one side mouth angle, this makes the pipe need paste fixedly again, so, because the influence of antiseptic solution, blood or secretion, often make the pipe paste insecure, because the doctor is absorbed in operation itself more, therefore the pipe often takes place the dropout incident, under the condition of having begun the operation, the pipe drops not only very dangerous, and it is great to carry out the trachea cannula degree of difficulty once more, because the intubate equipment is usually only clean and aseptic article, consequently also can increase the operation infection risk. The utility model discloses a general anesthesia mouth gag of peroral surgery, borrow the complete mouthful of artificial tooth mould of department of stomatology, cup joint the mould on patient's tooth, and utilize some mechanical structure, let the mould keep at the open state, make patient when doing the general anesthesia operation of peroral department, keep the opening action, can save anesthesia doctor for preventing that patient from stinging the bite-block that the pipe used, and set up fixed cover on last tooth mould, parts such as fixed pin and larynx hoop, can relax fixes the pipe on last tooth mould, and can be according to the operation demand at any time, quick transform pipe male position, when making things convenient for the doctor to operate, can also reduce the risk that the pipe drops, guarantee going on smoothly of operation.
