Surface anesthesia device suitable for hypopharynx and throat biopsy
Technical Field
The utility model belongs to the technical field of medical equipment, concretely relates to surface anesthesia device suitable for pharynx and throat's biopsy down.
Background
The laryngopharynx examination is the routine specialized examination of otolaryngology department, and when a doctor carries out the examination on a patient, because the pharyngeal reflex of part of the patient is sensitive, the surface anesthesia of the pharynx and the larynx is often required. The common method is to spray surface anesthetic (such as tetracaine) on the surface of pharynx and larynx mucosa, and the medicine is absorbed by mucosa to anesthetize peripheral nerve, so that local tissue pain is eliminated.
Hypopharynx and larynx biopsy is the most common and indispensable means for defining new biological properties of hypopharynx and larynx. In the process of carrying out biopsy of a new organism under an electronic laryngoscope, most patients can have obvious pharyngeal reflex, the biopsy parts are often not activated accurately, and the discomfort of patient choking cough, pain and the like can be reduced by properly using surface anesthetic, and the accuracy of biopsy can also be improved. At present, the common anesthesia device for the otolaryngological department is mainly a straight-head injection device with a certain angle. The anesthesia method can achieve a good anesthesia effect on the soft palate, the tongue root, the posterior pharyngeal wall and other parts, but cannot accurately spray or drip surface anesthesia medicaments to parts required by biopsy, such as vocal cords and ventricular cords, due to the fact that the anesthesia method cannot be operated under an indirect laryngoscope. This is the region where the new life is frequently generated in the throat, and stimulation of this region most easily causes the patient to choke and swallow, so that biopsy in this region cannot be performed smoothly.

Drawings
FIG. 1 is a schematic structural view of a topical anesthetic device suitable for biopsy of the hypopharynx and larynx according to the present invention;
names and sequence numbers in the figure:
the indirect laryngoscope comprises an indirect laryngoscope 1, a gun barrel 2, an extension pipe 3, a shower nozzle 4, a drug suction pipe 5, a grab handle 6, a trigger 7, a closing switch 8, a drug storage bottle 9 and a negative pressure device 10.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1:
as shown in figure 1, a surface anesthesia device suitable for hypopharynx and larynx biopsy is provided, which comprises an indirect laryngoscope 1 and an anesthesia gun, wherein the anesthesia gun comprises a gun barrel 2, an extension tube 3, a shower nozzle 4, a drug suction tube 5, a grab handle 6 and a trigger 7.
The barrel 2 is hollow and has a medicine storing bottle 9 in the middle, one end of the medicine storing bottle is connected with the handle 6, and the other end of the medicine storing bottle is a conical water outlet.
Stretch into 3 one ends of pipe and be connected with barrel 2 and the toper delivery port of depositing medicine bottle 9, the one end is connected with gondola water faucet shower nozzle 4 in addition.
The interior of the grab handle 6 is provided with a negative pressure device 10 which is communicated with the medicine storage bottle 99 through a negative pressure pipe.
The medicine suction tube 5 is communicated with a medicine storage bottle 9, and a closing switch 8 controlled by a button on the outer surface of the gun tube 2 is arranged at the communication position.
The trigger 7 is arranged at the corner of the grab handle 6 and the gun barrel 2 and is electrically connected with the negative pressure device 10 through a lead to be used as a switch for starting the negative pressure device 10.
