Description
Technical Field
The utility model relates to a medical auxiliary instrument, in particular to a head-wearing type head position correction auxiliary device for ophthalmology.
Background
In ophthalmic surgery, such as cataract intraocular lens implantation surgery or refractive corneal corrective surgery, axial astigmatism marking of the patient's cornea is performed prior to surgery to enable accurate astigmatism correction during surgery. When the cataract artificial lens is implanted, the correct axial position can be accurately implanted according to the position of a cornea mark, and when the cornea is in a cornea refractive correction operation, in order to avoid astigmatic axial position correction errors caused by eyeball self-rotation (oculotoricsion) in a lying position, the laser scanning of the cornea can be directly carried out according to the position of the cornea mark. Therefore, how to accurately mark the axis of the cornea and measure the accurate astigmatism axis before the operation is particularly important.
In the prior art, for example, a doctor uses a slit lamp to mark the axis of the cornea of a patient before surgery. The head of a patient is placed on a main support of a slit lamp, the forehead and the chin respectively support an upper support and a lower support, the patient horizontally watches the right front, a doctor observes a cornea through a microscope, the horizontal slit lamp is arranged, and a marking pen is used for marking a horizontal axis on the edge of the cornea. Because of the difference of the craniofacial skeleton structure of each person, even if the head is accurately fixed by the support, the head may be inclined, when a patient with a convex chin leans forward relatively, and vice versa, the head may lean backward relatively, and the head is not in a natural head position state, and the 6 eye muscle coordination of the two eyes and the head position in a normal natural upright state may be different. The head position distortion may be horizontal rotation distortion, left-right tilting distortion, or front-back tilting distortion. Any deviation causes self-rotation of the eyeball, which affects the correct corneal horizontal marking and axis of astigmatism measurement.
As shown in FIG. 1, the external muscles of the eyes act on the eyeball rotation. When both eyes are simultaneously looking at an object, the movements of both eyes must also be coordinated with each other. Wherein the contraction quantity of each muscle of 6 eye muscles of a single eye can generate different contraction tension along with the change of a fixation point, and the muscle can generate additional clockwise and anticlockwise rotation motions besides the up-down, left-right motions, that is, the self-rotation of the eyeball, for example, when the head leans against the slit lamp and is horizontally rotated and tilted to the right, the right eye will compensate for the forward fixation and rotate to the left (inward rotation), at this time, in addition to the contraction and tension increase of the right eyeball's internal rectus muscle, the right eyeball's upper and lower rectus muscles will also increase the tension to help the right eyeball to rotate inward, but at the same time, the right eyeball's upper and lower rectus muscles will generate additional eyeball rotation, if the contraction tension of the superior rectus muscle of the right eye is slightly greater than the inferior rectus muscle, a right intra-ocular rotation (clockwise rotation) may occur, thereby causing errors in the measurement and marking of the astigmatic axis of the eyeball. In the prior art, a level instrument is usually utilized to assist in marking the horizontal axis of a cornea, for example, a corneal astigmatism axis marker with the level instrument disclosed in patent No. CN201822197045.9 and a femtosecond laser cataract surgery marker with the level instrument disclosed in patent No. CN201921936217.8 all need a patient to sit upright and look straight ahead when in use, an eyelid opener fully exposes the cornea after dropping a surface anesthetic, the marker is placed on the cornea of the patient and finely adjusted by a handle to enable the level instrument to be in a horizontal state, and the neutrality of the vertical diameter of the cornea is determined according to the relative positions of three circular rings and the cornea. Therefore, the marker with the level gauge does not solve the problems of eyeball spin and the like caused by head position movement. Even if carry out accurate mark through the spirit level, eyeball still can lead to the stiff head position unnatural of health because of patient sits up, causes eyeball spin, and the position of mark still has the error.
Moreover, a patient needs to perform a plurality of items of ophthalmic optical measurement items before operation, slight head deflection which is difficult to distinguish by naked eyes can exist in any measurement, for example, when the axis of astigmatism is measured, the head slightly tilts forwards in the items of the computer optometry instrument, slight head tilting backwards occurs in the items of the comprehensive optometry instrument, the measurement errors of the axes of astigmatism of the two items are superposed to cause larger measurement errors of the axes of astigmatism, and the operation and error risks of a doctor are increased.
