Description
Technical field
The utility model relates to medical instruments fields, belong to a kind of auripuncture dress that hospital's ear-nose-throat department outpatient service uses
It sets, it particularly relates to a kind of Tympanostomy device.
Background technique
Acute and chronic secretory otitis media is ear-nose-throat department common disease, and clinical symptoms are ear muffle, Hearing, main
Middle ear hydrotympanum is shown as, common treatment method is auripuncture.Due to no special Tympanostomy device, generally make
With No. seven long syringe needles, traditional 1ml syringe is connect.The first piercing method, operator wear frontal mirror, and left hand adjusts the position of ear canal
It sets, the right hand is held after needle punctures successfully from eardrum front lower place, change the fixed puncture needle of left hand, right hand pumpback syringe piston backward, with
Absorb hydrops in tympanum.Second method punctures under ear endoscope, and operator's left hand holds otoscope, and the right hand is worn out by puncture needle
After eardrum, syringe piston pumpback hydrops is controlled by assistant.This method need by two people cooperate complete, and require operator and
Assistant's good teamwork.Above two method, if it cannot be guaranteed that enough stability, will lead to auripuncture point and expand or rouse
Film tearing, increases the risk of the tympanic membrane perforation；If puncture needle is pierced into too deep simultaneously, promontory of tympanum can be injured and cause the violent otalgia of patient, increased
Add patient suffering, cause unnecessary conflict between doctors and patients, it could even be possible to injured patient's auditory ossicular chain and round window membrane, lead to serious listen
Power decline.Auripuncture is a current clinically used treatment method, and for beginner, auripuncture is otology study
A difficult point, need, if one-time puncture is unsuccessful, to cause suffering for patient by long-time training and psychology is frightened,
The confidence of operator has been hit simultaneously.
Therefore, clinically it is badly in need of a kind of special tympanocentesis needle for facilitating clinical practice at present, if can be in puncture needle
On design a device, adjustable vacuum magnitude is adjusted back after auripuncture success with the device of the adjusting vacuum magnitude
Draft, then do not need that operator is hand-off can to extract middle ear effusion, to considerably increase the stability of operation.Have at present
Some patents of invention improve tympanocentesis needle, but are mostly conceived to puncture needle shape and aspirate the improvement of form, side
Just visual field exposure, for the invention in terms of puncture needle pumpback control, there is not been reported, but this is exactly that we clinically face most
Crucial and urgent problem to be solved.
Utility model content
Technical problem to be solved in the utility model be in view of the above shortcomings of the prior art, provide it is a kind of can illumination,
It can make to facilitate unlatching vacuum suction while doctor's single-hand handling & puncture needle, and be adjustable the auripuncture of the size of negative pressure suction force
Device.
