Abstract
The invention discloses a eustachian tube aspirator which comprises a connecting tube, wherein the front end of the connecting tube is provided with an attraction port, the attraction port is fixedly connected with the connecting tube, the attraction port is communicated with the connecting tube, and the rear end of the connecting tube is provided with a negative pressure device. The connecting pipe penetrates through the eustachian tube of a human body, the suction port is abutted against the root of an ear, the tail end of the connecting pipe is led out from the nasal cavity and then connected with the negative pressure device, so that smoke can be sucked away from the nasal cavity through the eustachian tube in the ear operation, and the smoke generated in the ear operation is effectively removed.
Description
Technical field
The present invention relates to a kind of medical instrument articles, especially push away the auxiliary instrument of ear operation.
Background technique
When carrying out ear operation, when using electric tool, such as bipolar hoe scaler either laser is cut
When cutter, a large amount of smog can be all generated.Smog not only influences whether the visual field of doctor, but also disease included in smog
The substances such as poison and its DNA, pernicious gas also will affect the health of patient and doctor, so, it is needed in the course of surgery with attraction
The sucking head of device quickly absorbs smog caused by operation.But since operation is carried out in ear, due to ear
Space is limited, and relatively, only one external opening of ear, so causing the removal effect of smog unsatisfactory.
Summary of the invention
The technical problem to be solved by the present invention is the smog generated in ear operation can effectively be removed by providing one kind
The auxiliary instrument on hand removed.
The solution that the present invention solves its technical problem is: a kind of Eustachian tube aspirator, including connecting tube, the connection
The front end of pipe is equipped with suction port, and the suction port is fixedly connected with connecting tube, and the suction port is connected to connecting tube, the connection
The rear end of pipe is equipped with negative pressure device.
As a further improvement of the above technical scheme, the suction port is in horn-like, suction port it is outer go to without leave after
It gradually decreases, the rear end of the suction port connects with connecting tube.
As a further improvement of the above technical scheme, the connecting tube is silica gel material.
As a further improvement of the above technical scheme, the negative pressure device includes vacuum pump and hose, the hose with
The rear end of connecting tube is connected by interface.
As a further improvement of the above technical scheme, the cross section of the suction port is oval.
As a further improvement of the above technical scheme, the maximum outside diameter of the suction port is 3-5mm.
The beneficial effects of the present invention are: the present invention is by the Eustachian tube using connecting tube through human body, then suction port is supported
The firmly root of ear, then the end of connecting tube is drawn from nasal cavity connects negative pressure device again, so that in ear operation, smog
It can be attracted away via Eustachian tube from nasal cavity, effectively remove the smog generated in ear operation.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, to form more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Referring to Fig.1, the front end of a kind of Eustachian tube aspirator, including connecting tube 1, the connecting tube 1 is equipped with suction port 2, institute
It states suction port 2 to be fixedly connected with connecting tube 1, the suction port 2 is connected to connecting tube 1, and the rear end of the connecting tube 1 is equipped with negative pressure
Device 3.
Tympanum in human body ear be not it is completely enclosed, it is communicated with the outside world by one " Mi Dao ".This Mi Dao
It is exactly Eustachian tube, its opening in tympanum is ostium tympanicum.Enter from ostium tympanicum, channel here is mainly made of bone, channel
It is sideling downward, and is tapered, arrived only one two millimeters of isthmus internal diameter, this is most narrow place.Followed by forward, by
Gradually open, " building materials " are also changed to based on cartilage, and for the end in channel in pharynx nasalis, entire channel is about 35 millimeters.On channel
Under difference in height be 15~25 millimeters, the liquid of such pharynx nasalis is not easy " sailing against the current " into middle ear.Eustachian tube it is main
Effect is the pressure adjusted in tympanum, and in addition there are also the effects of drainage, and the secretion in tympanum is discharged.The pharynx drum of nearly tympanic segment
Pipe is often open state；The Eustachian tube of nearly nasopharynx section can reduce or expand, and be usually to close, when swallowing, yawn, sing
Or it is just opened when firmly blowing one's nose.
Eustachian tube is exactly utilized as communicating passage in the Eustachian tube aspirator of the application, using connecting tube by tympanum and nose
Chamber is connected to by force, and negative pressure device is then accessed from nasal cavity, carries out attraction row to smog caused by the operation carried out in tympanum
It walks, so that ear operation progress is more smooth.
Be further used as preferred embodiment, the suction port in horn-like, suction port it is outer go to without leave after gradually
It reduces, the rear end of the suction port connects with connecting tube.The cross section of suction port is oval, and the maximum of the suction port
Outer diameter is 3-5mm.Horn-like suction port can allow suction port preferably to cooperate with tympanum, to the maximum extent by tympanum
In smog attract walk.
It is further used as preferred embodiment, the connecting tube is silica gel material.The outer surface of connecting tube will have enough
Flexibility, guarantee the surface for not injuring Eustachian tube when through Eustachian tube, at the same the inside of connecting tube to have it is enough
Intensity guarantees the Eustachian tube for strutting occlusion.The shape of connecting tube can be adapted to the change in shape with Eustachian tube simultaneously, will even
Adapter tube is made into stair-stepping pipe, and the caliber of front end is greater than the caliber of rear end, so that connecting tube can be preferably through pharynx
Tympanic canal.
Be further used as preferred embodiment, the negative pressure device includes vacuum pump and hose, the hose with connect
The rear end of pipe is connected by interface.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
