The utility model belongs to the medical appliance field, in particular relates to a lens capsule scale. The utility model is mainly made by connecting the scale through an anti-skid handle, the scale part is in the shape of flat tongue, and laser grinding scales are arranged at the front side of the scale part. The utility model can overcome the defaults in prior art, thus being more suitable for intraocular distance measurement and positioning in the intraocular operation. The utility model has the advantages of high accuracy, non-invasion, real time, convenient operation and safety during the intraocular measurement, and can obviously improve the operation accuracy, thus to improve the operation effects.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of micro-surgical instruments-lens capsule scale that is used for ophthalmologic operation.
Background technology
Over nearly 30 years, ophthalmologic operation especially intraocular surgery has carried out the transition to the micro-operative technique epoch.Along with the progress of surgical technic, increasing intraocular surgery need be found range accurately, locate intraocular structure in art.
Existing accurate measurement means comprises methods such as the outer scale of eye, string rule, UBM, but still has all inconvenience in actual the use.Said method all is to measure outside eye, clinical practice shows, measured data and the real data of the outer scale chord rule of eye has bigger deviation, can not satisfy the requirement of accurate quantification operation, described UBM method checking process is loaded down with trivial details, can not carry out in operation process, and certainty of measurement also is difficult to reach submillimeter level.So present existing measurement means can not satisfy the requirement of quantitative ophthalmologic operation with rapid changepl. never-ending changes and improvements.
Summary of the invention
The purpose of this utility model provides a kind of micro-surgical instruments that is used for ophthalmologic operation, is specifically related to a kind of medical lens capsule scale.This utility model lens capsule scale can overcome the defective of prior art, is fit to more carry out ophthalmic range finding and location in the quantitative intraocular surgery, improves the accuracy of operation, reaches better surgical effect.
This utility model lens capsule scale mainly is connected scale 3 by handle with scale junction 2 by Anti-slip handle 1 and makes.
This lens capsule scale adopts medical no-reflection stainless steel material to make.Described handle portion is the anti-gliding style design of embossing, and length is 15cm, and the transverse section is circular, diameter is 4mm, and scale portion is flat tongue type, and length is 12~18mm, width is 1.8~2.5mm, and thickness is 0.6mm, and that its making requires is smooth, no-reflection, no corner angle and burr.Wherein there is laser polishing scale in the scale front, with 0.25~1.00 millimeter be unit, amount to 10~40 grades.Handle and scale junction 3 are 120 °~160 ° angles.
This utility model be applicable at ultrasonic emulsification for cataract or have that carry out accurately capsule size, artificial intraocular lenses location etc. to tearing in the intraocular surgery such as crystal eye intraocular lens implants, noinvasive, real-time ophthalmic measuring operation, easy operating in the art, easy.Through clinic trial, the result confirms safe and effective.The design of this lens capsule scale is succinct, easy to use, can obviously improve the degree of accuracy of operation, thereby improve surgical effect.

The specific embodiment
Embodiment 1
Adopt the no-reflection medical stainless steel to make the lens capsule scale, described handle portion is the anti-gliding style design of embossing, and length is 15cm, and the transverse section is circular, and diameter is 4mm; Scale portion is made flat tongue type, and length is 18mm, and width is 2.0mm, and thickness is 0.6mm, makes to require smooth, no-reflection, no corner angle and burr, and wherein the scale front is provided with laser polishing scale, with 0.5 millimeter be unit, amount to 25 grades; Handle and scale junction angle are 120 °.Above-mentioned lens capsule scale is tried out, in many focuses of cataract ultrasonic emulsification associating Arrey/Restor intraocular lens implants, because artificial intraocular lenses's optic diameter is 6mm, it is 5.0~5.5mm that the capsule diameter is torn in requirement, must be positioned at simultaneously the pupil center, before tearing capsule, accurately measure the pupil maximum gauge with this scale, get with the pupil center is that center of circle row diameter is the belt continuously capsule that tears of 5.0~5.5mm, Nang Kou mates with crystal optics portion size before having guaranteed behind the implantable artificial crystal, and the position is accurate.
Make the lens capsule scale with the no-reflection medical stainless steel, described handle portion is the anti-gliding style design of embossing, and length is 15cm, and the transverse section is circular, and diameter is 4mm; Scale portion length is 14 mm, and width is 1.8mm, and thickness is 0.6mm, and that its making requires is smooth, no-reflection, no corner angle and burr, and wherein the scale front is provided with laser polishing scale, with 0.25 millimeter be unit, amount to 40 grades.Handle and scale junction angle are 160 °.Above-mentioned lens capsule scale is tried out, in crystal eye artificial intraocular lenses Verisis implantation correction high myopia is arranged, must pass through pupil center to artificial intraocular lenses's 2 lines of two fixation point positioning requirements on iris, and 2 equal apart from pupil center, and requiring pupil diameter simultaneously is 2.0mm~2.5mm.Accurately measuring pupil diameter and keep pupil diameter with viscoelastic agent and miotic with the ophthalmic scale in the art is 2.0mm~2.5mm, the implantable artificial crystal is before iris, accurately locate artificial intraocular lenses's fixation point with this lens capsule scale again, guarantee fixedly artificial intraocular lenses of the coaxial back of its optic and pupil.
