Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a levator palpebrae superioris muscle strength measuring device. Background Art
[0002] Ptosis is one of the most common diseases in ophthalmic plastic surgery. It is caused by partial or complete loss of function of the levator palpebrae superioris muscle or Muller muscle, or other reasons. One or both upper eyelids are significantly lower than the normal position. In mild cases, the pupil is partially covered, and in severe cases, the pupil is completely covered. It not only affects the appearance and vision, but also causes amblyopia. The treatment of ptosis is mainly corrected by surgery. The strength of the levator palpebrae superioris muscle plays a very important role in the choice of surgical method. Therefore, it is very important to correctly measure the strength of the levator palpebrae superioris muscle.
[0003] The existing traditional method: ask the patient to look straight ahead, press the frontalis muscle at the eyebrow arch with the left thumb to block the traction of the frontalis muscle on the upper eyelid, ask the patient to open and close the eyelid with force, and use a ruler in the right hand to measure the range of motion of the upper eyelid margin when opening and closing the eyelid, that is, the levator palpebrae superioris muscle strength (expressed in mm). Disadvantages: During the measurement process, the tester may move the fingers pressing the frontalis muscle, resulting in uneven pressure. When the ruler is used in the right hand for measurement, the ruler has no fixed fulcrum and will move due to shaking, affecting the accuracy of the measurement. Although the existing upper eyelid muscle strength detection device is not affected by the operator's technique, the device is complex in design, has high operating requirements, and is not practical, so it has not been widely used. Summary of the invention
[0004] The utility model proposes a new technical solution for the prior art, and designs a levator palpebrae superioris muscle strength measuring device which is simpler in structure and easier to use than the existing levator palpebrae superioris muscle strength detecting device, and is more accurate than the traditional method.
[0005] The technical solution adopted by the utility model is: a levator palpebrae superioris muscle strength measuring instrument, comprising a brow arch pressure plate and a buckle device; the buckle device comprises a base fixedly arranged on the brow arch pressure plate and a clamping plate flipped and covered with the base; the clamping plate is flexibly connected to the rear edge of the base, and the clamping plate movably flips over the top edge of the base; the edge where the clamping plate covers the base is provided with a forward protruding opening flange, and the base is correspondingly provided with a recessed position for accommodating the opening flange.
[0006] A further technical solution is: the buckle device is arranged at a central position 3 mm away from the lower edge of the eyebrow arch pressure plate.
[0007] A further technical solution is that the brow arch pressing plate is in a flat oval shape.
[0008] A further technical solution is that the brow arch pressing plate and the buckle device are integrally formed of rubber material.
[0009] Its further technical solution is: it also includes a cotton thread used in conjunction with it, and the cotton thread is installed and fixed on the buckle device.
[0010] Due to the adoption of the above technical solution, the levator palpebrae superioris muscle strength measuring device of the utility model has the following beneficial effects:
[0011] 1. The utility model has a simple structure, consisting of an eyebrow arch pressing plate 1 and a buckle device 2, and has a simple manufacturing method and low cost.
[0012] 2. The utility model is easy to use. When measuring, use a marking pen to mark the intersection of the eyelid margin and the cotton thread when the eyelid is open and closed as the marking point. When the marking measurement is completed, remove the cotton thread and use a ruler to measure the distance between the two marking points on the cotton thread, which is the activity amplitude of the levator palpebrae superioris muscle, that is, the levator palpebrae superioris muscle strength. The force-bearing area of the eyebrow arch pressure plate 1 of the utility model is larger than that of the measurer's thumb, so that the force is more uniform when pressing. The eyebrow arch pressure plate 1 is made of rubber material and is attached to the skin on the eyebrow arch during measurement. It is not easy to slide. The buckle device 2 fixes the cotton thread. When measuring, the cotton thread is straightened vertically to form a cotton thread tension fulcrum at the position of the buckle device 2. The measurement will not be affected by slight movements of the patient's head position and eye position, and the measured data is more accurate.
[0013] 3. The utility model is made of rubber material, which is easy to disinfect and can be used repeatedly. The cotton thread is disposable and a new cotton thread is replaced each time a measurement is made, so the use cost is low.

[0021] like Figure 1 to Figure 2 As shown: a levator palpebrae superioris muscle strength measuring instrument, comprising an eyebrow arch pressure plate 1 and a snap device 2 for fixing cotton thread; the snap device 2 comprises a base 21 fixedly arranged on the eyebrow arch pressure plate 1 and a clamping plate 22 flipped and covered with the base; the clamping plate 22 is flexibly connected to the rear edge of the base 21, and the clamping plate 22 is movably flipped to the top edge of the base; the edge where the clamping plate 22 covers the base 21 is provided with a forward protruding opening flange, and the base 21 is correspondingly provided with a recessed position for accommodating the opening flange.
[0022] like Figure 3 As shown, the levator palpebrae superioris muscle strength measuring device of this embodiment also includes a cotton thread 3 used therewith, and the cotton thread 3 is installed and fixed on the buckle device 2.
[0023] The eyebrow arch pressing plate 1 and the buckle device 2 described in this embodiment are integrally formed and made of rubber material, so that the eyebrow arch pressing plate 1 is attached to the skin on the eyebrow arch during measurement and is not easy to slide. The eyebrow arch pressing plate 1 is flat and oval, and the bottom is relatively flat. The size of the flat oval is about 3 cm in the major axis and about 1.5 cm in the minor axis; the buckle device 2 is arranged at a central position 3 mm away from the lower edge of the eyebrow arch pressing plate 1. The base 21 is attached to the top edge of the eyebrow arch pressing plate 1; the splint 22 is rectangular, and the size of the rectangle is about 2 mm × 5 mm. When in use, open the splint by opening the flange, and place the cotton thread on the base surface; then press the opening flange to snap it into the concave position set in the base 21, and the cotton thread is clamped and fixed on the buckle device 2. The cotton thread is a disposable medical cotton thread, which is hygienic, safe and easy to replace.
[0024] The method of using this levator palpebrae superioris muscle strength measuring device:
[0025] When using, place a white cotton thread, buckle the splint to fix the cotton thread, place the eyebrow arch pressure plate 1 on the frontalis muscle above the eyebrow arch, so that the lower edge of the eyebrow arch pressure plate 1 is just level with the lower edge of the eyebrow, the buckle device 2 is on the midline of the upper eyelid margin, and the cotton thread just passes through the midline of the upper eyelid margin (see Figure 4), the operator's left thumb presses the frontalis muscle fixator to block the frontalis muscle from pulling the levator palpebrae superioris muscle, the patient closes the eyelids naturally, and the patient is asked to pull the cotton thread vertically with his hand. The operator's right hand marks the cotton thread with a marker pen at the intersection of the cotton thread and the midline of the upper eyelid margin, and asks the patient to open his eyes with force. The operator uses a marker pen to make another mark on the cotton thread at the intersection of the cotton thread and the midline of the upper eyelid margin. After the marking measurement is completed, the splint is opened, the cotton thread is taken out, and the distance between the two marked points on the cotton thread is measured with a ruler. This is the range of motion of the levator palpebrae superioris muscle, that is, the levator palpebrae superioris muscle strength (expressed in mm). Since the eyebrow arch pressure plate 1 and the buckle device 2 are an integrated structure, when measuring, the cotton thread is vertically tightened, and the buckle device 2 is a fulcrum. The measurement will not be affected by slight movements of the patient's head position, and the measured data is more accurate.
