Description
Technical Field
The invention belongs to the field of medical equipment, relates to a device for measuring the distance of the light reflected by the eyelid margin and the muscle strength of the upper eyelid, and particularly relates to a device capable of avoiding the interference of subjective factors and accurately measuring the distance of the light reflected by the eyelid margin (The Marginal Reflex Distance, MRD value) and the muscle strength of the upper eyelid.
Background
Ptosis refers to the incomplete or complete loss of function of lifting the upper eyelid muscles (ocular innervation) and the Muller smooth muscles (sympathetic innervation), so that the upper eyelid exhibits partial or complete ptosis, the light person covers part of the pupil, and the serious person's pupil is covered completely, which not only impairs the beauty and affects the vision, but also the congenital upper eyelid prolapse patient may cause severe amblyopia.
The procedure of shortening the eyelid muscles is one of the main clinical procedures for treating congenital, senile, traumatic or other types of ptosis. The levator upper eyelid shortening operation maintains the original walking and movement direction of the muscle and meets physiological requirements, so that the aim of better beautifying can be achieved. The operation is to judge the required muscle quantity to be excised in the operation according to the sagging amount of the patient's lifting blepharos, so that the effect of correcting the sagging of the upper eyelid is achieved, and therefore, the accurate judgment of the sagging amount of the lifting blepharos before operation is a key for ensuring the success of the operation.
It is currently internationally accepted that the eye lid margin photopic distance (MRD value) is used to reflect the eye lid muscle lifting force and press the arch of the eyebrow during measurement to eliminate the help of the frontal muscle to the eye lid lifting force and eliminate the possibility of some false eye lid droops. The specific process is that a measurer orders the patient to look up, a flashlight irradiates the pupil center of the patient, light is reflected by the pupil center, the measurer holds a common ruler, the zero scale is aligned to the upper eyelid center eyelid margin, and the distance from the light reflection point to the eyelid center eyelid margin, namely the MRD value, is read. Wherein the distance between the light reflection point and the central eyelid margin of the upper eyelid is MRD1 value; the distance from the light reflection point to the central lid edge of the lower eyelid is MRD 2. The patient's arch is pressed by the other hand, and the patient is instructed to look upward, and the MRD1 value is read. And judging the muscle strength of the blepharomy lifting according to the change of the MRD1 values of the two times, so as to estimate the muscle quantity required to be resected before operation.
However, the existing measurement method for the muscle strength of the eyelid is operated by a pure manipulation, and the measurement result has close relation with the manipulation of an operator, if the operator does not press the arch of the eyebrow vertically, the measurement of the muscle strength can be influenced by a little angular deviation, and the larger or smaller sagging amount can be read. Or the condition reflection phenomena such as eye closure and the like of a general patient can occur after the light irradiation, thereby affecting the excision amount of muscles in operation, causing insufficient or overcorrection of operation and causing operation failure. And the original measurement method has complicated steps and long time consumption. Patients, especially children patients, are not easy to cooperate with doctors, and are also the reasons for causing large errors and affecting the operation effect. Therefore, it is necessary to develop a set of objective integrated measurement equipment which is not affected by the manipulation of the operator, so as to improve the accuracy of the measurement of the muscle strength of the upper eyelid, thereby improving the therapeutic effect of the operation. While no instrument or device dedicated to measuring the muscle strength of the levator palpebral muscle is yet seen in the market.

Further, a cursor 52 is further provided on the ruler 5, and the cursor 53 can slide along the surface of the ruler 5.
When the blepharo-optical distance (MRD) and the blepharo-myodynamia measuring device provided by the invention are used for measuring the blepharo-myodynamia of a patient, the I-shaped gasket 2 is slid to a proper position along the first through hole, the I-shaped gasket 2 is positioned at the front part of the eyebrow arch, the luminous element 6 is positioned at the upper part of the center of the upper eyelid margin, the groove 42 of the arch pressing piece 4 is aligned with one end of the second through hole 23 of the I-shaped gasket 2, and the protruding part of the arch pressing piece 4 is inserted into the second groove 211. The arch pressing piece 4 and the H-shaped gasket 2 can relatively move along the axial direction of the cylindrical rod 31, and the arch pressing piece 4 and the H-shaped gasket 2 are relatively fixed along the direction perpendicular to the axial direction of the cylindrical rod 31. And the arch compression piece 4 is placed at the arch position of the patient, the lifting lugs 11 at the two sides can be connected with ropes or rubber bands and the like, and the curved surface fixing piece 1 is fixed on the head of the patient along the arch through the ropes or the rubber bands and the like.
The conical surface end 312 of the cylindrical rod 31 slowly rotates from the other end of the second through hole, passes through the cuboid connecting piece 22 and presses against the eyebrow bow pressing piece 4 to fix the eyebrow bow.
The light emitting element 6, such as a spotlight, is moved down to the vicinity of the pupil along the second connecting piece 61, the power is turned on, the light emitting element 6 emits light, the position of the light emitting element 6 is finely adjusted, the light of the light emitting element 6 is vertically irradiated at the center of the pupil of the patient, the locking structure is locked, the length of the light emitting element 6 is fixed, the zero scale value of the moving cursor 52 is aligned with the pupil reflecting point, the patient is ordered to look at head-on, the distance between the eyelid margin of the upper eyelid and the pupil reflecting point is ordered to look at, and the distance between the eyelid margin and the pupil reflecting point is ordered to look at upward. And then obtaining the levator blepharomy muscle strength grade of the patient according to the difference value of the two measured MRDs and a standard comparison table of the levator blepharomy muscle strength grade, thereby preparing a corresponding operation scheme and realizing accurate diagnosis and treatment.
According to the MRD and the device for measuring the muscle strength of the lifting blepharos, provided by the invention, the arch of the eyebrow is fixed when the muscle strength of the lifting blepharos is measured, so that the error in the measuring process is reduced. And when the MRD is measured, by using a decrement method, the phenomenon that the opening size of the upper eyelid is influenced due to conditional reflection when the pupil of a patient is irradiated by the light-emitting element is avoided, and the obtained data is more accurate. The ruler and the standardized measuring tool are of an integrated structure, so that corresponding data can be directly read out, errors are further reduced, the accuracy of the data is improved, and the standardized measuring tool can be fixed on the head of a patient, so that the operation is simpler and more convenient.
The above description of the specific embodiments of the present invention has been given by way of example only, and the present invention is not limited to the above described specific embodiments. Any equivalent modifications and substitutions for the present invention will occur to those skilled in the art, and are also within the scope of the present invention. Accordingly, equivalent changes and modifications are intended to be included within the scope of the present invention without departing from the spirit and scope thereof.
