Description

The maxillary sinus chamber is towards suction pipe

Technical field

This utility model relates to a kind of Medical Irrigator tool, is specifically related to a kind of maxillary sinus chamber towards suction pipe.

Background technology

Opening maxillary sinus chamber (namely removing the part paries medialis maxillaris) afterwards in the nasal endoscope operation, usually need to wash the hole chamber, maxillary sinus since its space structure approximate tip down, the irregular hexahedro vertebral body of form, single duct elbow suction pipe when carrying out irrigation of maxillary sinus usually externally the limited zone of sidewall direction wash, flushing for rear wall, antetheca, upper wall, lower wall is all very limited, this mainly is to be subject to that the elbow suction pipe can not rotate freely in the long and narrow space of nasal cavity, can only be with elbow sidewall direction outward.

For addressing the above problem, notification number is that the utility model patent of CN2159222Y discloses " a kind of maxillary sinus chamber irrigator ", this irrigator has the syringe pipe of the tubular that a rear end can be connected with syringe, the front end of syringe pipe has a flushing hole, in addition, also have at least four flushing holes on the anterior side of syringe pipe.Therefore the syringe pipe of this utility model can wash the hole intracavity more all sidedly owing to be provided with a plurality of flushing holes in the side of the front portion of syringe pipe, can improve the success rate of operation and improve cure rate.But, because the space of nasal cavity own is narrow and small, under the conchoscope guiding, Chang Wufa enters two suction pipes (add the camera lens of endoscope, in fact have three tubes will enter the middle nasal meatus zone of nasal cavity, this is impossible substantially) simultaneously: a responsible bath, another root then is responsible for suction, therefore that root pipe that usually will absorb water in the practical operation is put in the prenaris place, because the emptying in time of nasal cavity water liquid usually causes accumulating of nasal cavity water liquid.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of maxillary sinus chamber that not only can wash the maxillary sinus chamber comprehensively and can in time absorb flushing liquor towards suction pipe.

The technical scheme that this utility model solves the problems of the technologies described above is:

A kind of maxillary sinus chamber comprises an outer tube towards suction pipe, and the front end of this outer tube has an elbow, and the sidewall of this elbow is provided with a plurality of apopores, and the rear end of this outer tube is provided with the injection joint that is connected with syringe; Be provided with interior pipe in the outer tube, front end of pipe extends to the front end of elbow in this, and is somebody's turn to do the front port of interior pipe and the external communications of elbow, and rear end of pipe is connected with suction pump in this.

A preferred version of the present utility model wherein, is positioned at the apopore aperture of described elbow crook greater than the apopore aperture of outer crook.Adopt the purpose of this technical scheme to be, for elbow, maxillary sinus antetheca difficulty touches, and rear wall relatively easily touches, if be arranged to the apopore of interior crook and outer crook identical, the developing result of maxillary sinus antetheca (last before comprising, just preceding and preceding lower area) can be slightly poor so, and be arranged to the apopore of interior crook bigger, the apopore of outer crook is arranged to less, then bigger current can be guided to impact maxillary sinus antetheca zone (go up before comprising, just before and preceding lower area), thereby improve whole developing result.

A preferred version of the present utility model, wherein, the front end of interior pipe inserts in the front end-plate of elbow, and interior pipe front end face is concordant with the outer surface of the front end-plate of elbow.Adopt the purpose of this technical scheme to be, be conducive to fixing interior pipe on the one hand, on the other hand, make that the front end of whole syringe pipe is concordant, avoid stabbing skin.

A preferred version of the present utility model, wherein, the knee of elbow is the circular arc bending.The bending of circular arc is convenient to stretch into the maxillary sinus intracavity by otch, handled easily, and be difficult for stabbing skin.

In this utility model, also be provided with apopore on the front end-plate of elbow, with further raising developing result.

In this utility model, the bent angle of elbow is 60 °～120 °, preferred 90 °.

Operation principle of the present utility model is: flushing liquor is behind injector to inject, enter elbow from the circular passage between outer tube and the interior pipe, and rush at each sidewall in maxillary sinus chamber the apopore from the elbow sidewall, under the suction pump effect, the flushing liquor of maxillary sinus intracavity is outside by sucking in the front port of interior pipe and discharging, flushing liquor forms at the maxillary sinus intracavity and inwardly manages the current that front port compiles from all directions, thereby secretions or the deposit of maxillary sinus intracavity are discharged.

Described as seen by top operation principle, this utility model compared with prior art has following beneficial effect:

1, in this utility model, owing to be provided with a plurality of apopores at the sidewall of the elbow of the front end of outer tube, flushing liquor can make whole maxillary sinus chamber all can obtain flushing from all directions towards each sidewall of maxillary sinus chamber; Simultaneously owing in outer tube, be provided with interior pipe, and should in the front port of pipe and the external communications of elbow, the rear end is connected with suction pump, so the flushing liquor of maxillary sinus intracavity can go out by interior bank of tubes in time, has avoided accumulating of nasal cavity flushing liquor;

2, adopted the dual structure of outer tube and interior pipe in this utility model, with respect to using two independently pipes in the prior art, designs simplification not only, volume reduces, and operation is also convenient, flexible, has improved success rate and the quality of operation.
