Embodiment 1

[0036] like Figure 1 to Figure 5 As shown, the MRD and the levator muscle strength measurement device provided by the present invention include a curved surface fixture 1 , an I-shaped gasket 2 , a push rod 3 and a light emitting element 6 .

[0037] The arc length of the curved surface fixing part 1 is 160 mm, the central angle of the circle where the curved surface fixing part 1 is located is 70 °, the width of the curved surface fixing part 1 is 25 mm, and both ends of the curved surface fixing part 1 are provided with a lifting lug 11. A rope or a rubber band can be connected to the top, and the curved surface fixing part 1 is fixed on the patient's head along the eyebrow arch by the rope or the rubber band, so as to fix the eyebrow arch.

[0038] A rectangular first through hole 12 is provided at a distance of 8 mm from the lower edge of the curved surface fixing member 1. The width of the first through hole 12 is 3 mm. The length of the first through hole 12 is not limi...

Embodiment 2

[0050] like Image 6 As shown, another kind of eyelid margin reflection distance (MRD) and levator muscle strength measurement equipment provided by the present invention includes a curved surface fixture 1 , an I-shaped spacer 2 , a push rod 3 and a light emitting element 6 .

[0051] The arc length of the curved surface fixing part 1 is 250mm, the central angle of the circle where the curved surface fixing part 1 is located is 60°-80°, the width of the curved surface fixing part 1 is 30mm, and both ends of the curved surface fixing part 1 are provided with a lifting lug 11, Can connect rope or rubber band etc. on the lug 11, by rope or rubber band etc., curved surface fixture 1 is fixed on patient's head along brow arch.

Abstract

The invention provides eye lids margin illumination distance and levator palpebrae superior muscle strength measuring equipment. The equipment comprises a hook face fixing piece, a luminous element, a geisoma compressing piece and a pulling rod, wherein the hook face fixing piece is provided with at least one first through-hole, the pulling rod is connected to the geisoma compressing piece after being inserted into the first through-hole, and the light of the luminous element can form a liminescent printing point in the most protruding point of the cornea. The eye lids margin illumination distance and levator palpebrae superior muscle strength measuring equipment can perpendicularly fix the geisoma when levator palpebrae superior muscle strength is measured, and thus operation errors is reduced during measurement. An integrated measurement way makes a straightedge directly attach under the measuring device, the operator can directly read a corresponding number value, thus the operation time is shortened, the errors are further lowered, and precision of data is improved. Therefore, insufficient correction or overcorrection caused by insufficient ptotic amount judgment is avoided, and the surgery effect is improved. The whole standardized measuring tool can be fixed at the head of a patient, thus the operation is simpler and convenient, and the compatibility and the compliance of the patient are improved.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a measuring device for the light reflection distance of the eyelid margin and the strength of the levator muscle, in particular to a device capable of avoiding the interference of subjective factors and accurately measuring the light reflection distance of the eyelid margin (The Marginal Reflex Distance, MRD value) and equipment for levator muscle strength. Background technique [0002] Ptosis refers to the insufficiency or complete loss of the levator muscle (innervated by the oculomotor nerve) and Müller smooth muscle (innervated by the sympathetic nerve), resulting in partial or complete drooping of the upper eyelid. Covering not only hinders the appearance and affects vision, but also may cause severe amblyopia in patients with congenital ptosis. [0003] Levator muscle shortening is one of the main clinical procedures for the treatment of congenital, senile, traumatic or other ...
