Description
Technical field
The invention belongs to operation medical apparatus and instruments, relate in particular to the apparatus that ophthalmology is used when implementing intraocular surgery.
Background technology
In anatomy of human eye, corpus ciliare is the ring-type organ between crystalline lens and vitreous body, and ciliary processes is capsulociliary radial projection.When some ophthalmic diseases, ciliary processes meeting pathologic bulge increases or atrophy diminishes.At present whether ciliary processes there is is the judgement of pathologic size variation, depend on and take ultrasound investigation as main Medical Imaging inspection.In eyeball of normal person, approximately there are 70 left and right ciliary processes.Existing medical literature is recorded ciliary processes normal size for being about 2mm, wide about 0.5mm, high about 1mm.The source of this normal value is also according to the statistical analysis to Medical Imaging data.And these medical imaging means are difficult to ciliary processes size dimension to quantize, often there is error in observed result and practical situation, has time error also very large, thereby hinder or mislead the diagnosis of disease and treatment.
In some ophthalmologic operation, need again scene to measure entity.For example treat the solidifying art of glaucomatous light, need to measure the number of ranges of the ciliary processes of being coagulated the number of ranges of the ciliary processes of excising by light and being retained, and at this moment can not use the Medical Imaging means such as ultrasound investigation.
Therefore, in Physiological Anatomy, need to after being measured, numerous individual entities statistics set people's ciliary processes physiology normal value; For the needs of patients that ciliary processes pathological proliferation or atrophy occur, with measurement data, objectively respond; In disease treatment, need measurement data to determine the amount to the amount of cyclophotocoagulat and reservation.But there is no at present, live body eye inner tissue is implemented to the utensil of directly measuring.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of, when intraocular surgery, eye ciliary processes is implemented to the utensil of directly measuring.
The utensil that the present invention implements directly to measure to eye ciliary processes is called intraocular ruler.Intraocular ruler of the present invention comprises handle, main scale, secondary chi three parts, and main scale near-end is connected with handle, and main scale far-end is connected with secondary chi near-end.Main scale and secondary chi are strip-shaped structure, and main scale is longer, and secondary chi is shorter, and the suitable length of main scale is 30-50mm, and the suitable length of secondary chi is 3-5mm; Main scale and secondary chi are advisable with wide, and suitable width is 0.5-1.5mm; Main scale and secondary chi are advisable with uniform thickness, and its thickness should be thin unsuitable thick under the prerequisite that keeps certain rigidity.Its rigidity should be difficult for bending when contacting with part tissue of eye.Intraocular ruler of the present invention should be used metal material to make, and suitable thickness is 0.5-1.5mm.Main scale and secondary chi are L shaped layout under using state.Main scale and secondary chi all arrange scale.Within the scope of the forward end 4mm of main scale, scale is set, secondary chi total length all arranges scale.The density of scale should be suitable for perusal under the cooperation of endoscope.The handle of intraocular ruler of the present invention is for ease of hand-held size and shape.
When some needs, can be that main scale is wider by the structural design of main scale and secondary chi, secondary chi is narrower; Main scale is thicker, and secondary chi is thinner.Secondary chi width is equivalent to the 1/2-3/4 of main scale width, and secondary chi thickness is equivalent to the 1/2-3/4 of main scale thickness.Wider, thicker main scale is conducive to stability and the ruggedness of intraocular ruler.
Main scale and secondary chi can arrange scale in one side, also can at upper and lower surface, scale be all set simultaneously.When upper and lower surface all arranges scale, the scale unit on two sides and density can be identical, also can use respectively up and down the scale density that different long measures is different with density is set.For example, a kind of preferred scale set-up mode is, the front scale of main scale and secondary chi is metric system long measure, and back side scale is mile; Another kind of preferred scale set-up mode is, the front scale of main scale and secondary chi is metric system long measure, and the back side arranges the labelling that can represent the ciliary processes normal in size value that medical circle is generally acknowledged.
As optimization, main scale and secondary chi are two parts, in main scale distal portion and secondary chi close end, rotating shaft are set, and by the two combination, formation is rotationally connected.
Intraocular ruler using method of the present invention is: for major-minor chi integral type, the fixing intraocular ruler of right angle conjunction type, from limbus of corneae auxiliary incision, direction of rotation is sent into ophthalmic, uses main scale to measure ciliary processes cross-directional length, uses secondary chi to measure ciliary processes vertical-direction length.For major-minor chi, be rotationally connected type intraocular ruler, secondary chi turned to main scale overlapping, the two is ruler state, from limbus of corneae auxiliary incision, sends into ophthalmic anterior chamber.Operation enters in camera oculi anterior from another cut-out of limbus corneae with endoscope.With termination portion of endoscope, promote the secondary chi of intraocular ruler, secondary chi is turned to and the main scale state that meets at right angles, implement the measurement to ciliary processes.
Intraocular ruler of the present invention is for measure the size of ciliary processes when intraocular surgery, convenient, direct, accurate.With the present age multiple ophthalmological instruments be used in conjunction with, made up the blank of ciliary processes being implemented to direct measuring appliance.
Accompanying drawing explanation
Accompanying drawing is intraocular ruler structural representation of the present invention.
The parts that number in the figure is represented or position be, 1-hands handle; 2-main scale and handle junction; 3-main scale; 4-major-minor chi connection rotating shaft; 5-secondary chi.
The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Each parts of intraocular ruler of the present invention are all used metal material to make, and wherein the preferred nichrome of main scale and secondary chi is made.Handle 1 length 80mm-120mm, can be designed to any hand-held shape of being convenient to, for example round roller shape, flat rod shape.Main scale 3 near-ends can be welded as a whole with handle 1, also can be designed as Spliced movable syndeton 2.Main scale 3 and the movable connected structure 2 of handle 1 are convenient to depositing and postoperative cleaning, sterilization under resting state.
The optimum size of major-minor chi is, the long 40mm of main scale 3, and the long 3mm of secondary chi 5, major-minor chi width is 1mm, and major-minor chi thickness is 0.5mm.Main scale distal portion 4 forms and is flexibly connected with rivet combination with secondary chi close end 4.Each is arc by an angle skiving for main scale distal portion and secondary chi close end, and when main scale 3 and secondary chi 5 turn to L-shaped crossing at right angle state, L shaped exterior angle is curved.So structure can reduce the probability of intraocular ruler harmed eye inner tissue.
The front of main scale 3 and secondary chi 5 arranges scale, is metric system grade long measure.Main scale 3 back sides arrange scale, are the length in the horizontal direction of ciliary processes under the generally acknowledged normal physiological state of medical circle, and secondary chi 5 back sides arrange scale, are ciliary processes length in the vertical direction under the generally acknowledged normal physiological state of medical circle.
