Description

Middle ear mastoidectomy drain ventilation duct

This utility model belongs to the medical apparatus technical field, relates to a kind of mastoid process drain ventilation duct that can be used for the clinical diagnosis and treatment otitis media.

Otitis media is the commonly encountered diseases and the frequently-occurring disease of hals,Nasen und Ohrenheilkunde, and malpractice not only influences patient's audition, hinders one's work, and easily causes severe complication (as facial paralysis and the inside and outside complication of cranium etc.), so occupy critical role clinically.Research about otitis media cause of disease aspect in the past mainly concentrates on dysfunction of eustachian tube and infects two aspects, think that eustachian tube obstruction is the main cause of otitis media, and the pharyngotympanic tube isthmus under a cloud be the position of easy obstruction, therefore in treatment, pay attention to salpingian ventilation drain, its common drain inflammatory exudate method is auripuncture or incision and tube adapter for drum membrane etc., but clinical effectiveness and unsatisfactory.In recent years some studies show that, most pharyngotympanic tube are unimpeded during otitis media, eustachian tube obstruction seldom is the main cause that causes otitis media, and pathological observation does not see that pharyngotympanic tube has tangible inflammatory lesion yet, and irrelevant with the sticking perichondral pathological changes order of severity of pharyngotympanic tube isthmus.

At the problems referred to above, focus on the pathological observation research that interior ventilation drainage channel pathology block of this utility model designer by various secretory otitis media temporal bone sections are done, in ear ventilation drainage channel is easy to by the myxedema of inflammatory in the discovery, adhesion, encapsulated effusion and granulation tissue are blocked to some extent, obstructive position shows higher transudate in later half tympanum zone than preceding half tympanum zone and accumulates rate and granulation tissue incidence rate, this just means that also it is to cause that inflammatory exudate lodges in the middle ear Background Region that the inflammatory pathology of ventilation drain in the middle ear system blocks, cause granulation tissue that the main cause of chronic otitis media takes place also and then forms, so focus on the transudate of drain middle ear Background Region clinically, in ear ventilation drain is the particularly key of chronic otitis media of treatment otitis media in improvement or the reconstruction.

Because the anatomical features of middle ear mastoidectomy, interior vent passages (drum gorge, aditus ad antrum, umbilicus cape gorge etc.) often blocks because of inflammation, cause the inflammatory exudate retention to go up tympanum in the back, as tympanum rear portion, attic, aditus ad antrum and mastoid cavity etc., the long-standing pathologic of inflammation is changed to the mucosa inflammatory edema, oozes out, suppuration, encapsulated effusion, granulation tissue formation, mucosa basement membrane thickened, adhesion cicatrix fibrosis and tympanosclerosis etc., above-mentioned variation is if handle proper ending at any period, otherwise may form the vicious cycle of pathological process.Facts have proved, adopt diagnosis and treatment project, will help to improve and eliminate the obstruction of interior ventilation drainage channel, for clinical diagnosis and treatment otitis media have been founded a brand-new and effective path at mastoidea position Tube Drain transudate.

The purpose of this utility model is to provide a kind of middle ear mastoidectomy drain ventilation duct that is used for drain middle ear Background Region transudate according to the essence of otitis media pathomechanism.

Be used to realize that the technical solution of foregoing invention purpose is such: the middle ear mastoidectomy drain ventilation duct that is provided has a siphunculus of being made by silastic material, is provided with a belt buckle-like pipe close and an ear shape seam sheet respectively in the afterbody mouth end both sides of pipe.In the clinical use, siphunculus is placed patient's middle ear mastoidectomy district, promptly can also carry out radiography with clear and definite middle ear system obstructive position by flushing, drain and the ventilation of siphunculus endoporus realization to middle ear system, thus the selection of accurate instruction clinical treatment method.

Below with reference to accompanying drawing this utility model content is described further.

Fig. 1 is the side direction structural representation of a specific embodiment of this utility model.

Fig. 2 overlooks to sketch map for Fig. 1 structure.

Referring to accompanying drawing, this mastoid process drain ventilation duct is made by the silastic material with good biocompatibility, comprises siphunculus 1, belt buckle-like pipe close 2 and ear shape seam sheet 3 three parts.Said siphunculus 1 is an equal coupling pipe or its afterbody aperture as shown in the figure siphunculus greater than anterior aperture, implement in the structure, the internal diameter and the length of siphunculus 1 all vary with each individual, be applicable to the various types of mastoid process situations of children's to the adult, select suitable caliber also to be convenient to use the inflammatory activity situation that ear endoscope is observed middle ear mastoidectomy, this pipe tail structure can connect syringe, convenient flushing and suction.Belt buckle-like pipe close 2 is connected with at siphunculus afterbody mouth end, utilizes it can be convenient to first plugging observation before tube drawing.After siphunculus places patient's mastoid process, generally can tube drawing after the ventilation drain is normal.Can be convenient to ventilation duct is fixed on the mastoid region skin by suture at the ear shape seam sheet 3 that the afterbody mouth of pipe is set.

Of the present utility model simple in structure, easy to use, cheap, respond well, the mastoid process PTBD that adopts this mastoid process drain ventilation duct and do might substitute traditional simple mastoidotomy to the otitis media early stage patient, the mastoid process postoperative patient is put pipe, ventilation drainage obstruction in can improving, it is intact or create conditions for auditory rehabilitation in the future to preserve ossicular chain.Product described in the utility model can be widely used in the treatment of various early stage, chronic and intractable otitis media, has good social benefit and economic benefit.

Claims (1)

1. A kind of middle ear mastoidectomy drain ventilation duct is characterized in that having a siphunculus of being made by silastic material (1), is provided with a belt buckle-like pipe close (2) and an ear shape seam sheet respectively in the afterbody mouth end both sides of pipe.
