Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, it is a ciliary muscle stimulator for adjusting intraocular pressure. BACKGROUND

[0002] Trabecular meshwork pathway is the important anatomical structure of draining aqueous humor, regulating outflow resistance of aqueous humor and determining intraocular pressure level. The trabecular meshwork pathway lesion causes the outflow resistance of aqueous humor to increase, and the intraocular pressure to rise, which is the most important reason leading to the occurrence and development of glaucoma. Relevant research has confirmed that the trabecular meshwork pathway pumps aqueous humor out of the eye in a pulsatile manner and returns to the systemic circulation. The ciliary body is mainly composed of muscle fibers, and the longitudinal muscle thereof crosses the sclera and inserts into the trabecular meshwork. Previous studies have shown that the ciliary body-trabecular meshwork tension state is an important factor for regulating the aqueous humor drainage function of the trabecular meshwork pathway. The contraction of the ciliary muscle pulls the trabecular meshwork, opens the Schlemm's canal, and promotes the outflow of aqueous humor, so that the intraocular pressure quickly returns to the baseline level. Therefore, the ciliary body becomes an important anatomical site for regulating intraocular pressure.

[0003] At present, the treatment of glaucoma includes drug treatment and surgical treatment. The monitoring index of curative effect mainly relies on intraocular pressure measurement. However, in the prior art, the treatment of glaucoma mostly depends on the discovery of high intraocular pressure, then surgery and drug treatment. This form often misses the treatment opportunity for acute glaucoma, and the surgery is generally a traumatic surgery, which is difficult to perform and requires professional high-level ophthalmologists to implement. When acute glaucoma occurs, it cannot be guaranteed that the patient can receive effective treatment within the time from the onset of the disease to the reception of the surgery. Moreover, once glaucoma occurs, it is crucial to reduce the intraocular pressure, and there is no simple and effective auxiliary device in the existing glaucoma treatment that can rapidly reduce the intraocular pressure. UTILITY MODEL CONTENT

[0004] Therefore, the purpose of the utility model is to provide a ciliary muscle stimulator for adjusting intraocular pressure. Considering that the ciliary body is an important anatomical site for regulating the outflow of aqueous humor and is attached to the inner surface of the sclera, a brand-new ciliary muscle stimulator for adjusting intraocular pressure is proposed. Once high intraocular pressure is found, the electrode can be turned on during the eye examination by using a gonioscope to stimulate the ciliary muscle, promote the pumping out of aqueous humor, and adjust the intraocular pressure to decrease.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a ciliary muscle stimulator for adjusting intraocular pressure, which comprises a gonioscope, an electrode sheet and an electrode stimulator. The gonioscope comprises a corneal contact lens in contact with the cornea. The corneal contact lens is provided with an extended edge extending to the limbus. The surface of the extended edge is provided with a groove. The electrode sheet is placed in the groove, and the electrode sheet is connected to the electrode stimulator.

[0006] Further preferably, the gonioscope further comprises an observation mirror, a reflecting mirror and a mirror housing; the observation mirror and the contact lens are arranged at two ends of the mirror housing, and the reflecting mirror is arranged on the inner side of the mirror housing.

[0007] Further preferably, the extended edge of the contact lens extends to a position 3.5 mm behind the limbus.

[0008] Further preferably, the groove is arranged at a position 2-3 mm behind the limbus.

[0009] Further preferably, the gonioscope further comprises a control handle, and the electrode stimulator is arranged on the control handle, and a plurality of keys are arranged on the control handle.

[0010] Further preferably, the gonioscope further comprises a foot control, and the foot control is connected with the electrode stimulator, and a plurality of keys are arranged on the foot control.

[0011] Further preferably, the keys comprise switch keys and gear adjustment keys, and the switch keys and the gear adjustment keys are connected with the electrode stimulator.

[0012] The ciliary muscle stimulator for adjusting intraocular pressure disclosed in the application has at least the following advantages compared with the prior art:

[0013] The electrode piece is integrated on the gonioscope, which allows the doctor to treat the patient immediately after diagnosing that the patient has glaucoma. For angle-closure glaucoma, especially acute angle-closure glaucoma, the pupil block / ciliary ring block can be quickly broken, the intraocular pressure is reduced to a safe range, the immediate treatment effect is achieved, or a safer operation opportunity is provided for subsequent incisional surgical treatment. For open-angle glaucoma, the treatment purpose of restarting the pumping function of the trabecular meshwork can be achieved through this technology, and reference and basis are provided for subsequent surgical strategy of glaucoma minimally invasive surgery.

[0018] The utility model is further described in detail below by means of the drawings and specific embodiments.

[0019] As Figures 1-2 The utility model provides a ciliary muscle stimulator for adjusting eye pressure, including gonioscope 1, electrode piece 2 and electrode stimulator 3, gonioscope 1 includes the contact lens of cornea 4, the contact lens of cornea 4 is equipped with the extended edge, the extended edge extends to the limbus of cornea, the surface of the extended edge is equipped with the recess, electrode piece 2 is placed in recess, electrode piece 2 is connected electrode stimulator 3.

[0020] Gonioscope 1 still includes observation mirror 101, mirror 102 and mirror shell 103, observation mirror 101 and cornea 4 contact lens are equipped with the both ends of mirror shell 103, and mirror 102 is equipped on the inner side of mirror shell 103.

[0021] The extended edge of cornea 4 contact lens extends to the place 3.5mm behind cornea 4 limbus.

[0022] The recess is arranged at the place 2-3mm behind cornea 4 limbus, and is located the opposite side of mirror 102, so that the doctor can observe the effect after stimulation through mirror 102 in the subsequent operation electrode piece process.

[0023] As Figure 2 Still include control handle, electrode stimulator 3 is arranged on control handle, and control handle is equipped with a plurality of keys. The key includes switch key and gear adjustment key, and switch key and gear adjustment key are connected with electrode stimulator 3, and the example of placing electrode stimulator 3 in the inside of control handle is shown in the drawing, and whether the electrode stimulation is started can be realized by pressing switch key on control handle 6, and the gear can be adjusted by pressing gear adjustment key.

[0024] For example, the up-regulation key can increase the frequency and / or amplitude applied to electrode piece 2, and the down-regulation key can reduce the frequency and / or amplitude applied to electrode piece 2.

[0025] Or the ciliary muscle stimulator can also include a plurality of electrode pieces 2. For example, one gear can control only one electrode piece to start, and two gears can control two electrode pieces to start, that is, the number of started electrode pieces can be increased by operating the up-regulation gear key, and the number of started electrode pieces can be reduced by operating the down-regulation key.

[0026] As Figure 3Different from the foregoing embodiments, a foot control is arranged, the foot control is connected with the electrode stimulator 3, and a plurality of keys are arranged on the foot control. The keys include a switch key and a gear adjusting key, and the switch key and the gear adjusting key are connected with the electrode stimulator 3. For example, the up key on the left pedal and the down key on the right pedal.

[0027] In use, the doctor contacts the corneal contact lens of the gonioscope with the cornea, and the electrode sheet is placed in the groove and at 2-3 mm behind the corneal limbus; when the doctor judges that it is glaucoma and detects that the intraocular pressure is persistently high, the doctor presses the switch key to start the electrode sheet to stimulate the ciliary muscle to contract, increase the outflow of aqueous humor, and restore the intraocular pressure to a normal level. For patients in the late stage of open-angle glaucoma, because the function of the trabecular meshwork passage to sense the change in intraocular pressure and adjust the rhythm is lost, the ciliary muscle can be stimulated by the electrode sheet at a fixed rhythm to artificially reconstruct the pumping function of the trabecular meshwork, maintain the stability of the intraocular pressure, and adjust the stimulation intensity according to the target intraocular pressure. During the discharging process of the electrode sheet, the doctor can determine the treatment time by observing the shape of the iris under the gonioscope and the opening of the angle of the anterior chamber. After treatment, the intraocular pressure is measured. The doctor can determine the number of electrode sheets to be turned on according to the patient's condition and the measured data of the intraocular pressure, and press the up key or the down key on the handle to increase or decrease the number of electrode sheets; or adjust the frequency and / or amplitude of an electrode sheet to adjust the gear.

[0028] The present application has the following potential therapeutic effects:

[0029] Acute angle-closure glaucoma: stimulating the ciliary muscle, rotating the ciliary process backward and inward, causing the iris attachment point and the iris to shrink and flatten, opening the entrance of the anterior chamber angle, reducing pupil resistance, increasing the flow of aqueous humor from the posterior chamber to the anterior chamber, and finally flowing into the trabecular meshwork passage to rapidly reduce the intraocular pressure.

[0030] Malignant glaucoma: ciliary ring block is the root cause of the occurrence of malignant glaucoma, which is the most difficult type of glaucoma to treat and has the worst prognosis. There is currently no rapid and effective treatment measure. Electrically stimulating the ciliary muscle increases the distance between the ciliary process and the equator of the lens, relieves the ciliary ring block, and increases the circulation of aqueous humor.

[0031] Open-angle glaucoma: electrically stimulating the ciliary muscle, longitudinally contracting the muscle, increasing the trabecular meshwork tension, and observing the phenomenon of blood flowing back to the Schlemm's canal under the gonioscope, reducing the resistance in the trabecular meshwork area, and increasing the outflow of aqueous humor.

[0032] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
