Description
Technical field
This utility model relates to a kind of eye surgery otch measuring appliance, the length of otch such as especially a kind of transparency cornea tunnel incision that is used for accurately measuring the ophthalmology cataract operation, limbus of corneae tunnel incision, scleral tunnel otch or the measuring device of other external coats that needs accurate measuring length and surgical incision.
Prior art
The incision length of modern day cataract operation is generally 2.6～3.2mm, otch is little, and certainty of measurement requires high, and existing surgery measuring appliance, ophthalmologic operation otch measuring appliance particularly,, shortcomings such as certainty of measurement low, inconvenient operation single because of size are difficult to satisfy application demand.Cataract operation treatment field is numerous with the patient at the ophthalmic industry element, development is rapid, satisfactory effect is celebrated, in recent years, the novel art formula of a kind of " bimanual microphacoemulsificaandn ultrasonic emulsification for cataract " by name has been released in international ophthalmology's cataract operation treatment field again, operative incision length shortens dramatically than traditional operation, only is 0.9～1.4mm.At present, about the bibliographical information of this art formula, deliver for existing many pieces abroad, only this center has pertinent literature to deliver at home.Because of cutter use aspect disunity, each research is very not consistent about the report of operation length yet.Recently the high folding property artificial intraocular lenses who various cooperation micro-incision both hands phacoemulsifications occur, but this type of high folding property intraocular lens waits clinical groping to the subject range of incision length.Thereby, be necessary accurately to measure operative incision, make the operative incision standardization of new art formula by clinical practice, grope to guarantee the best incision length of operation safety execution, and before measuring existing high folding property implantation of artificial lens, the incision length of postoperative, for introducing and promote clinical manifestation that novel art formula, development be applicable to the dedicated tool of new art formula and estimate novel intraocular lens to vast ophthalmology worker all by significance.
The survey tool of using in the ophthalmologic operation mainly contains two classes at present: a class is a branch formalism measuring device.The shortcoming of this class measuring device is (1) only distance of energy measurement tissue surface point-to-point transmission, can't stretch into the otch inwall, measures incision length in tissue; (2) certainty of measurement is low.Another kind of is single-piece sonde-type otch measuring device, the less at home application of this class measuring device, and abroad the structure of this series products is mainly the strip foil of different in width, bonding jumper is inserted otch measure.The shortcoming of existing this type of measuring device is (1) one-piece design, needs during measurement to select and change between a plurality of measuring devices, operates complicated; (2) measuring device leading portion foil exposes, and subjects to wearing and tearing, thereby causes certainty of measurement to reduce.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, provide a kind of and can make things convenient for, accurately measure the length of otch such as transparency cornea tunnel incision, limbus of corneae tunnel incision, scleral tunnel otch of ophthalmology cataract operation or the measuring device of other external coats that needs accurate measuring length and surgical incision, and be convenient to preserve, not easy to wear.
For reaching above purpose, the technical scheme that this utility model is taked is: this utility model measuring device comprises the gage outfit 1 of a processing precise, this gage outfit 1 is connected drive link 2 front ends, gage outfit 1 can be connected by the pin thread nut with drive link 2, also can adopt other modes to connect or directly welding.The rear end of drive link 2 links to each other with control piece; The drive link and the control piece that are connected with gage outfit are installed in the sliding tray of cover casing 3; The drive link that is connected with gage outfit can axially move in sliding tray; By promoting control piece, the gage outfit of drive link front end is extended shell, measures.The exposed parts of control piece is the control knob 4 of a small wrench spline structure, is installed in the horizontal draw-in groove 7 short on cover casing 3 panels, and in use, the operator promotes the control knob along horizontal draw-in groove, and the control piece of the drive link that promotes in succession is released gage outfit.For ease of preserving, can design two screens (see figure 1)s respectively at the two ends of horizontal draw-in groove, like this under preservation state and measurement state, the control knob is to be stuck in the screens at horizontal draw-in groove two ends, so that fixation measuring head, and in pushing course, pull the control knob can make columniform drive link along longitudinal axis rotation 45 degree, wait to arrive and recover former angle when measuring the position again.
The gage outfit processing precise that this utility model measuring device is adopted, machining accuracy are 0.02mm, and certainty of measurement is 0.1mm (as Fig. 4 figure below).Measuring device is divided into four kinds of specifications, the measuring device of every kind of specification all comprises the gage outfit of 6 sizes, measuring range is respectively 0.9～1.4mm, 1.5～2.0mm, 2.1～2.6mm, 2.7～3.2mm, and the gage outfit front end is carved with corresponding dimension mark, can be for patient's reading under the operating microscope direct-view.
This utility model measuring device can be a single-piece; Also the gage outfit of a plurality of different sizes can be installed in the flat cover casing that has multiple tracks parallel sliding groove, constitute dull and stereotyped combined type ophthalmologic operation otch measuring device with a plurality of gage outfits; Can also be according to the theory of mechanics of commercially available bull ball pen, a plurality of gage outfits with different size are installed in the cover casing of pen type, constitute the pen type combined type ophthalmologic operation otch measuring device with a plurality of gage outfits, pen type combined type ophthalmologic operation otch measuring device includes extension and contraction control element 5 and spring 6 parts (see figure 4)s in addition.
This utility model measuring device in use, user is as long as promote the button of measuring device control piece gently, gage outfit is promptly extended, to measure length or other external coat that needs accurate measuring length and the surgical incision of otch such as transparency cornea tunnel incision, limbus of corneae tunnel incision, scleral tunnel otch; The measuring device of composite members design is equipped with the multiple tracks sliding tray on its cover casing, and the operator can choose wantonly and wherein release gage outfit together and measure, and is improper as length, can switch to another sliding tray easily, releases the probe of another gage outfit and measures.
The gage outfit 1 of this utility model measuring device, the material of spring 6 are medical stainless steels, and the material of drive link 2, control knob 4, extension and contraction control element 5 and shell 3 can be made with medical stainless steel or the nontoxic macromolecule polymeric material of heatproof (as politef).
The advantage of this utility model measuring device is:
1, easy to use, simple to operate.
2, can guarantee certainty of measurement for a long time.Because when not using this measuring device, as long as promote the button of measuring device control piece once more gently, in the retraction measuring device shell, gage outfit does not expose, does not subject to wearing and tearing to gage outfit, guarantees certainty of measurement for a long time immediately;
3, simple in structure, cost is low.Except that gage outfit, drive link, control piece and measuring device shell be processing easily all, and with low cost;
4, easily sterilization.All parts of this measuring device all adopt the medical stainless steel manufacturing, can carry out autoclave sterilization to measuring device integral body very easily.
