Abstract

The utility model discloses a chamber angle separator comprising a separator main body and a handle, wherein, the separator main body is a circular arc-shaped cylindrical object made of hard material; the external diameter of the cylindrical object ranges from 0.45 to 0.60 mm; the radian of the separator main body is larger than that of an iris and smaller than that of a cornea; a plane surface is formed at the innerarc part of the separator main body near the end part thereof; the front outline of the plane surface is oblong; and the connections between each part of the chamber angle separator are round and smooth. The chamber angle separator is characterized in that a through hole can be formed in the main body of the chamber angle separator; the handle is made of hard material and connected with the connecting part at the bottom of the separator main body; and the handle can be dismounted from the separator main body. By adopting the chamber angle separator, the direct blunt separation of a closed or narrow chamber angle can be realized only by forming a puncture orifice on a transparent cornea, therefore, the success rate of chamber angle separation is improved. The chamber angle separator has the advantages that not only the operation of angle separation is simplified; but also the pain of a patient and the operation cost are reduced.

Description

The room corner separator

Technical field

This utility model relates to a kind of medical apparatus and instruments, the separation instrument that is used to separate the angle, room that particularly uses in the ophthalmologic operation.

Background technology

The cornea of human eye and iris at peripheral position mutually near and form angle, cry the angle, room, just the usually said angle of anterior chamber of people.Important structure such as trabecular reticulum are arranged in the angle, room, be the effusive major avenues of approach of aqueous humor,, just cause aqueous humor to flow out and be obstructed if periphery cornea iris is in contact with one another even adhesion is promptly closed at angle, medically said room, intraocular pressure raises because of gathering of aqueous humor, finally causes glaucomatous generation.Treat this oculopathy, on the wall of eyeball of Fang Jiaochu, cut an openning usually, set up an artificial channel, flow out outside the eye for unnecessary aqueous humor, thereby reach the effect that reduces intraocular pressure.Be the patient of this operation,, the holding capacity of external force weakened because the integrity of the wall of eyeball destroyed.Aqueous humor drainage that can only ophthalmic is unnecessary with stylish aqueous humor flow pass arrives under the conjunctiva of eyeball, and one of formation " filtering bubble " under conjunctiva, the existence that filters bubble has changed eye tear peripheral passage, cause ophthalmic uncomfortables such as xerophthalmia easily, when the bubble wall that filters bubble is thin, intraocular infection easily takes place, and the risk of grievous injury eyeball structure and function is arranged.Narrow or close the glaucoma that causes by the treatment of this room corner separator because of the angle, room, do not damage the integrity of wall of eyeball, because of its mechanism is the filtering function of closing the angle, room by reopening, do not have the existence that filters bubble, avoided because of filtering the potential risk that existence brought and the discomfort of bubble.

The utility model content

At the problems referred to above, the utility model proposes a kind of angle, isolating room, angle, room separating operation that is used to make, utilize this apparatus, the otch that need not undergo surgery just can be narrow or angle, the room separation of closing, and simplify therapeutic process greatly, and a recovery that helps performing the operation.Room of the present utility model corner separator comprises separator main body and handle, the circular arc column of separator main body for making by hard material, the scope of column external diameter is 0.45-0.60mm, the radian of separator main body is greater than the radian of iris and less than the radian of cornea, inner arc part at this separator main body is a plane near the place, end, this planar outline of facing is for oval, and the connection on the described room corner separator main body between the each several part all is a rounding off; Handle is that hard material is made, and removably is connected with separator main body.

Further, described separator main body inside along its length has through hole, and the length of separator main body is 10-15mm.

In addition, have connector between described separator main body and the handle, described separator main body is fixedlyed connected with connector, and it is as a whole to adopt the injection moulding mode to connect, and this connector can be sleeved on the handle.

Further, connector can be the plastics union joint of standard DB syringe needle, and handle can be the syringe of various different sizes.

Further, the afterbody of described separator main body is the one section radian opposite with the radian direction of this separator main body.

Adopt room of the present utility model corner separator, can realize the direct passivity separation at angle, room, changed traditional incision surgery therapeutic modality, not only simplified the isolating operation in angle, room, also alleviated patient's misery greatly, patient's operation risk and operation cost have been reduced, the human disease's that has wholesome effects simultaneously recovery.Angle, described room exclusion can repeat.

The room corner separator structural representation of Fig. 2 this utility model second embodiment;

Fig. 3 is that the A of Fig. 2 is to partial enlarged view.

The specific embodiment

Below in conjunction with accompanying drawing, a preferred embodiment of the present invention is described.Referring to Fig. 1, room of the present utility model corner separator comprises separator main body 1 and handle 2, separator main body is the whole arcual column that is, the diameter of this column is in the 0.45-0.60mm scope, the optional 10-15mm of length range, similar syringe needle, can make by metal or other hard material, described arcual radian is greater than the radian of iris and less than the radian of cornea, is a plane 4 in this column inner arc part 3 near the place, end, and this plane is about 1.5-3mm at length direction, and it joins by arc transition and outer arc part 5, form the head of separator main body, the described planar outline of facing is for oval.

When using this utility model to carry out angle, room lock out operation, at first use syringe needle on peripheral transparency cornea, to do an oblique puncture orifice, like this, room corner separator main body just can be goed deep in the anterior chamber by this puncture orifice, and arrival Fang Jiao position, because the radian of separator main body makes in operating process greater than the radian of iris and less than the radian of cornea, the structure of angle, the room adnexa that is difficult for damaging comprises cornea and iris.Utilize the planar section of room corner separator main body, push iris root, make the angle, room separately, expose the trabecular reticulum inner surface, recover its aqueous humor drainage function.This each coupling part of corner separator main body, room is a rounding off all, has avoided the damage of corneal puncture orifice.

In addition, as described in Figure 2, second embodiment for this utility model room corner separator can be shaped on through hole 6 in this separator main body, is used to inject medicine or other liquid, and as shown in Figure 3, for this is with foraminous end face partial enlarged view, its outline is oval.Separator main body can directly peg graft or be injection-moulded on the handle 2, also can be sleeved on the handle 2 by connector 7.But the plastics union joint of connector choice criteria DB syringe needle, separator main body can be made by injection molding way and adapter integral body, and handle can be selected the syringe of all size.Highly versatile not only, and can be as required to intraocular injection medicine or other required liquid.

In addition, the afterbody of separator main body also can be made has one section radian opposite with the radian direction of this main body, and radian is less than the radian of separator main body, like this, when carrying out angle, room lock out operation, the handle moving range reduces, and has reduced the damage of corneal puncture orifice.
