Abstract
The invention relates to a medical suction device (10) for sucking up liquids and particles, said device comprising a hollow base body (12) having a longitudinal axis X-X, an outer surface (16), an inner surface (14), and a suction opening (20). Part of said base body has a reflecting surface (24).
Description
The present invention relates to a kind of aspirator of dental, it is used in therapeutic process pumping liquid and granule from a patient oral cavity, this aspirator has a hollow matrix that has a longitudinal axis X-X, and this matrix has an outer surface, an inner surface and a suction opening.
When treatment and dental treatment, often need be with liquid that produces or the granule carrying-off that comes off.For example, when dental treatment, need in therapeutic process, saliva, flushing water and blood be siphoned away.For example also can accumulate at the water that is used to wash or implement a multi-functional injection, these water must be sucked away.Thus, use aspirator usually.In general, the tubular body that aspirator is made of plastics constitutes, and a flexible pipe is fixed on its end, and flexible pipe is connected with a pump.Then, can aspirate away fluid and the solid that hinders by flexible pipe or aspirator.
Also in other medical range, especially during surgical intervention, usually need in operation process, aspirate and walk blood, water and/or bone scraps etc.
Aspirator is not to be arrested by operative doctor or the surgeon oneself that undergoing surgery usually, but is arrested and operated by an assistant.Because the doctor's who undergos surgery two handss are used for operation, therefore this situation is necessary.For example, a boring bar tool is arrested through hands commonly used by an odontologist, and another hands is arrested a mirror, and the doctor can see the zone that needs treatment clearly by this mirror.This situation is equally applicable to the surgeon, often similarly needs to arrest two apparatuses operation process Chinese and foreign department doctor, yet also needs to use a mirror.
The shortcoming of said process is: two people, that is, and before operative doctor and assistant must be each other very closely stand or are sitting in patient to be performed the operation around zone to be performed the operation.If relate to suitable difficulty or need meticulous electrically operated operation fully, then this just can make the doctor who undergos surgery can feel to have interference.
Another shortcoming of bringing thus is: when operative doctor must use a medical tool, an aspirator and a mirror, he can indicate the assistant so.This is a special shortcoming just for odontologist, because dental operation often can carry out under the situation that does not have the assistant to help, yet also must extract fluid or chip out, and just had any problem this moment.
At last, what often hindered is that a general aspirator often uses with drill bit, this means that the work of using drill bit and aspirator simultaneously is very difficult.
Task of the present invention is to improve a kind of general aspirator, and this aspirator can use on the one hand with versatility, on the other hand, can help user and undergo surgery.Another task is, can make user also can implement some work or treatment under the situation that does not have an assistant.And this aspirator should be made cheap and use simple.
According to the present invention, this task is solved by the aspirator of a dental treatment.This aspirator is used for aspirating liquid and granule from patient's mouth, it has a hollow matrix that has a longitudinal axis X-X, this matrix has an outer surface, an inner surface and a suction opening, wherein, one reflecting surface is set, to enable to see clearly at least a portion in oral cavity by this surface in the zone of suction opening.
In addition, this task is solved by the aspirator of a dental treatment.This aspirator is used for aspirating liquid and granule in operation process from patient's mouth, it has a hollow matrix that has a longitudinal axis, this matrix has an outer surface, an inner surface and a suction opening, wherein, matrix is deformable longitudinally, so that the orientation of longitudinal axis X-X can change along all directions.
Can allow user that medical aspirator both can be used as pumping liquid and a particulate aspirator according to reflectance coating of the present invention also can be used as a mirror simultaneously and use.For example, this is very helpful for odontologist, because odontologist uses a boring bar tool generally must to hole simultaneously and aspirate when dental treatments.In addition, when seeing processed position, the doctor can not use a mirror.By means of aspirator of the present invention, now can make the doctor not have on the scene just can the enforcement of assistant to perform the operation.This aspirator also can be used as mirror simultaneously and uses.
Not to make whole aspirator be provided with a reflectance coating to carry out desirable function, on the contrary, just enough if this coating is arranged in the zone of suction opening.Both can be coated on the inner surface and also can apply on the outer surface.
Commercial aspirator general, that be used for the dental treatment purpose usually has a suction opening, and this opening stretches obliquely with respect to the main longitudinal extension direction of tubular matrix.The end with suction opening of tubular matrix also is not orthogonal to longitudinal axis but favours longitudinal axis ground extends.Thus, aspirator forms a form that tilts to extend, and like this, can easily be incorporated between buccal and the tooth.In such application scenarios, suction opening is then towards tooth, and long another part matrix, relative with suction opening leans against on the buccal.
In of the present invention one particularly advantageous embodiment, coating one reflectance coating on the inner surface of matrix, that can see the from the outside especially zone.Here it is means this: just as the odontologist of operation is accustomed to, aspirator can be directed to exactly the adnexa of tooth, that is, make suction opening towards tooth, then, tooth or zone to be performed the operation can be watched through the inner surface of reflection by suction opening by odontologist.That is to say, will mirror be extended for an extendible portion of aspirator.The advantage of doing like this is: swabbing action can not have a negative impact, and does not enlarge because leave the distance in zone to be sucked.Find in addition: for the same reason, can not increase by the air-breathing and sound that force generation.For the situation that in the face of the mirror of suction opening, comes to this, because this can produce disadvantageous air swirl.
In any case, if substitute coated inside, or in addition a reflectance coating being coated on the outer surface of matrix outside the coated inside, then is favourable again.
In another embodiment of the present invention, the suction opening that the end of aspirator has is expanded into toroidal, so that increase inner minute surface thus especially.If inner surface that can see, aspirator is used as reflecting surface by suction opening, then this just has meaning.Such horn mouth shape also can better maintenance soft tissue etc. be avoided.
According to the desired function that reaches,, then just has its meaning if the coating of reflection has an effect that amplify or that dwindle.On the one hand, can realize this effect in this wise: aspirator self has a shape protrusion or depression, has applied a corresponding reflection or a specular material on it; Perhaps, can realize above-mentioned effect in this wise: on matrix, place a mirror indent or an evagination.This mirror can be pasted up, although it also can be shaped integratedly with the material that constitutes matrix.Importantly, if use an additional mirror, then mirror should be connected with matrix like this,, should carry out the sterilization of aspirator easily that is.For this reason, provide certain methods here, use together so that mirror and the matrix of handing are coupled together in conjunction with common odontologist's mirror when using these methods.
Particularly advantageously be that use one has the insertable element of reflecting surface.This element removably is connected with aspirator in the suction opening zone.For example, aspirator can have a groove, can be for inserting this insertion element.As a result, this insertion element can optionally be changed and can be suitable for desirable occasion.This insertion element can have shape arbitrarily, and the face of reflection can be recessed, protruding or a different types.
Although aspirator according to the present invention can be with suitable material manufacture for the reason of cost, yet, make practical with plastic material.
According to the present invention, matrix can be constructed like this, that is, it can be adapted to desirable situation by plastic deformation.For example, this can realize in this wise: matrix is made with the plastics of a quite soft plastically deformable, makes operative doctor just it can be curved desirable shape by easy bending before using according to its purposes.Perhaps, can use one or more multi-directional ball joints.Importantly, the orientation of the longitudinal axis of aspirator can change along all directions.At an advantageous particularly is among the embodiment, and this spherojoint is arranged near reflector space, or reflector space self can or be configured to and can rotate with respect to reflector space around the longitudinal axis rotation.
Describe the present invention below with reference to the accompanying drawings in detail.Wherein:
Fig. 1 illustrates a diagrammatic side view according to aspirator of the present invention,
Fig. 2 illustrates the view of amplification of the end regions of the aspirator with a suction opening.
Shown in two views, a medical aspirator 10 has for example piped matrix 12 of a hollow, and this matrix has an inner surface 14 and an outer surface 16.In addition, matrix 12 have one linearly or as shown in embodiment, have one the bending longitudinal axis X-X.The advantage of this bending is that aspirator 10 can easily be placed on the position that needs treatment.
Matrix 12 has a connection opening 18 and a suction opening 20.This connection opening 18 is used for being connected to a unshowned flexible pipe here, and suction opening 20 is used for therefrom fluid or the chip by being sucked away.
In addition, an edge part 22 is shown in this embodiment, this edge part extends around the part of suction opening 20.For the aspirator 10 that uses in the dental treatment field, edge 22 can make patient's buccal or lip avoid zone to be treated better.In addition, this edge 22 makes aspirator not have sharp-pointed seamed edge in its suction opening zone.
According to the present invention, the part of aspirator 10 has a reflecting surface 24.This surface is represented with a cross hatched regions.Find: as in an illustrated embodiment, reflexible if the inner surface 14 of aspirator 10 is configured to for example become in this zone that can see clearly by suction opening 20, this is favourable.This just in time is for example in when treatment zone relative with tooth to be treated, because need in any case with close this zone of reflecting surface, so that clean effectively.In addition, because the ventilation constantly that is produced by the inner surface 14 of bleeding at matrix 12, this can guarantee that the surface of reflecting 24 do not coverd with by aqueous vapor.Yet in any case, as shown in Figure 1, the part that also can be outer surface 16 provides a reflecting surface 24.Edge 22 preferably also can be as shown in figure hundred to be configured to broad a little so that strengthen reflective surface area.
If matrix 12 all visible surfaces have the surface 24 of a reflection, or matrix 12 made by a reflecting material, then also are rational.
Aspirator 10 can have a light source in the zone of its suction opening 20, this light source illuminates the zone that can see by reflecting surface 24.For example, this can guarantee that this optical fiber extends along the length of matrix 12 by an optical fiber.Light source can directly be arranged in the zone of connection opening 18, if or this light source irradiation in photoconduction, what for to can be outside with light source arrangement.
Matrix 12 can be with all suitable material manufacture, and it is suitable that a kind of duroplasts is for example arranged, because it is sterilized easily.In order to guarantee that according to a modification of this invention matrix can be made with a kind of soft material partly, or part made the corrugated tube (Falgenbalg) that is similar to an inverted pleat.The advantage of this corrugated tube is that aspirator 10 can shorten or extend.
Aspirator 10 according to the present invention can make the personnel that undergo surgery from behind (from 12 o ' clock positions) patient is undergone surgery.Because the personnel of operation can bend over above patient from above, so this obviously alleviates the load at surgical staff back.Because aspirator is used for dental field just very frequently, so the present invention can make valuable contribution for the human engineering in improvement place.
The present invention is not limited to the above embodiments, and it also covers all equivalent embodiment.The variant of described embodiment is just given an example, and should not be construed as by any way to limit the scope of the invention.
