Description

A kind of multifunctional alcohol storage tank for PRK operation
Technical field
The present invention relates to a kind of operating theater instruments for PRK operation, belong to technical field of surgical instruments in medical science.
Background technology
PRK full name is (Photorefractive keratectomy), implies that photorefractive keratectomy, operation Principle is to loosen and strike off application excimer laser Central corneal front surface after corneal epithelium with ethanol, that is, remove epithelial layer Bowman's lamina and shallow-layer substrate, make anterior surface of cornea curvature decline with myopia correction.
Applicant, in the past PRK operation process, finds that existing operating theater instruments have a disadvantage that：
1）Not good enough in patient compliance, when frequently rotating eyeball, operator needs hand-held micro- toothed forcepss to grip eyeball, separately One hand-held corneal epithelium ring bores and is gently pressed on anterior corneal surface, and next step is added ethanol into corneal trephine and loosened the operation of corneal epithelium Can need to complete with assistant.
2）Micro- toothed forcepss are fixed to the single-point that is fixed as of eyeball, less effective, and such as patient still has generation when exerting oneself larger Eyeball is mobile or rotates, and leads to the risk of ethanol seepage, and the ethanol of seepage may cause to ocular necessarily to damage.
Content of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes one kind and facilitates one to carry out PRK operation Operate and can well fix the multifunctional alcohol storage tank of eyeball.
The present invention is that the technical scheme solving above-mentioned technical problem proposition is：A kind of multifunctional alcohol for PRK operation Storage tank, including handle, elastic component and circular ophthalmostat and corneal epithelium trepan, described ophthalmostat is used for Fixing eyeball, described corneal epithelium ring the pressure of the drill is located on cornea eye surface；Described corneal epithelium trepan is located at ophthalmostat Interior and be arranged concentrically with ophthalmostat, described ophthalmostat is fixed on handle one end, the bottom surface of described ophthalmostat and Inner ring surface intersection is made as a curved surface matching with cornea eye surface curvature, on the inner ring surface of described ophthalmostat It is formed with along its border uniformly and along axially extended at least two grooves of internal ring, solid on the external annular surface of described corneal epithelium trepan Surely there are at least two bar shaped connecting shafts, each bar shaped connecting shaft is goed deep in a groove and can be slided up and down along groove, described bullet In groove and its two ends is separately fixed on groove and one end of connecting shaft property part.
The present invention using the beneficial effect of technique scheme is：1）By the invention enables fixing eyeball and placing cornea The operating procedure of epithelium trepan can be completed by patient's one hand simultaneously, can voluntarily carry out next step to epithelium ring without assistant's cooperation Add ethanol in boring to loosen the operation of corneal epithelium, decrease human cost and improve efficiency；2）The present invention is by annular eye Ball holder is combined with epithelium trepan, to stablize eyeball from multi-faceted so that eyeball fixed effect is substantially better than existing surgical device Tool, reduces operation risk；3）By at least two bar shaped connecting shafts are fixed with the external annular surface of corneal epithelium trepan, often Individual bar shaped connecting shaft is goed deep in a groove and can be slided up and down along groove, can occur along preventing corneal epithelium ring to be drilled in after stress Rotation（Upset）, sports safety is stable；4）By by elastic component, in groove and its two ends is separately fixed at groove and connection On one end of axle, at least two bar shaped connecting shafts are fixed with the external annular surface of corneal epithelium trepan simultaneously, each bar shaped connects Axle gos deep in a groove and can slide up and down along groove, and so, corneal epithelium trepan can move up and down along groove and keep right The suitable pressure of anterior corneal surface.
The improvement of technique scheme is：Tiny convex-concave anti-slip veins or radial skid resistance strip are formed with described curved surface.
By tiny convex-concave anti-slip veins or radial skid resistance strip are formed with the curved surface of ophthalmostat, can be more preferable Fixing eyeball, prevents Rotation of eyeball.
One of change of technique scheme is：Described elastic component is that one end is fixed on groove top surface and its other end is fixed Compression spring on bar shaped connecting shaft top.
The two of the change of technique scheme are：Described elastic component is that one end is fixed on groove floor and its other end is fixed Extension spring on bar shaped connecting shaft bottom.
The three of the change of technique scheme are：Be formed with the inner ring surface of described ophthalmostat along its border uniform and Along axially extended two of internal ring, three or four grooves, corresponding described groove on the external annular surface of described corneal epithelium trepan It is fixed with two, three or four bar shaped connecting shafts.
The four of the change of technique scheme are：Described bar shaped connecting shaft is that middle part is solid with corneal epithelium trepan external annular surface The L-shaped connecting shaft that fixed ┣ shape connecting shaft or bottom and corneal epithelium trepan external annular surface are fixed.
The five of the change of technique scheme are：Described elastic component is used for driving corneal epithelium trepan to move up and down along groove And corneal epithelium ring the pressure of the drill is located on cornea eye surface.
Brief description
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is a kind of structural representation of multifunctional alcohol storage tank for PRK operation of the embodiment of the present invention.
Fig. 2 is the A of Fig. 1 to schematic diagram.
