Description
Technical Field
The utility model relates to a glaucoma operation medical instrument technical field, in particular to eyeball sclera marking tool.
Background
Glaucoma is the second leading blinding eye disease in the world, and is also an ophthalmological common disease and frequently encountered disease. It is characterized in that the optic nerve and the visual function are damaged due to the intermittent or continuous increase of the intraocular pressure, mainly symptoms such as optic nerve atrophy, visual deterioration, visual field reduction and the like, although the research on the glaucoma intraocular pressure reduction and the development of new drugs have made great progress, many glaucomas such as angle-closure glaucoma and congenital glaucoma need to be treated by surgery, and many cases of open-angle glaucoma and secondary glaucoma finally need to be treated by surgery. Surgery is therefore still one of the major means of glaucoma treatment.
The scleral flap is required to be made during most glaucoma surgery procedures. In actual operation, because no proper marking tool is available, an operator can only slightly mark by using a surgical instrument by virtue of own experience and then directly make an incision from the limbus to the completely opaque sclera by using a microsurgical knife, and the phenomena of skew and offset of the edge of the incision, uneven distance between the incisions and the like often occur during operation, so that the scleral flap is difficult to make in the operation, and the operation effect is directly influenced.
At present, the actual operation process of the operator roughly follows the scleral flap making method mentioned in the Chinese combined trabeculectomy operation expert consensus made by the ophthalmology division glaucomatology group of the Chinese medical society in 2017: a crescent-shaped knife is used to make a scleral flap with the limbus as the base, which is about 3mm by 4mm, for example, and 1/2 scleral thickness. Wherein, the edge of the scleral flap is clamped by a pair of forceps, turned over as much as possible, pulled downwards slightly, and the fibers between the scleral layers are cut in the direction almost flatly clinging to the sclera by a crescent knife and cut forwards to the inside of the transparent corneal limbus by 1 mm.
For how to make a scleral flap of, for example, 3mm × 4mm, in the surgical operation, an operator usually uses a sterile angle gauge to measure on the surface of the sclera and make a point-like indentation, and then uses a Marker pen after sterilization treatment to make a point-like mark (because the indentation mark is shallow, it will disappear soon), and then the operator cuts and makes the scleral flap with a scalpel between two points according to his own abundant surgical experience, but for the beginners and the doctors with a small amount of surgical experience, because of the softness of the scleral tissue and the complexity left by the previous operation, making a relatively regular scleral flap according to two points has great difficulty, and the phenomena of skew of the incision edge, deviation of the incision, uneven incision interval, etc. often occur, resulting in the difficulty in making the scleral flap in the operation.
In addition, clinically, most patients have undergone trabeculectomy before operation, and local scar is formed after operation, which is usually performed at the 12 th site of the eye. Therefore, when the ophthalmology angle gauge is used for marking the temporo-upper part and the nasal part of the eye, the size and the shape of the scleral flap can not be accurately determined, and the operation difficulty is increased.
The key point of the preparation of the scleral flap is that a marking tool which can directly mark the scleral flap contour of the eyeball does not exist at present, and an operator only adopts a method which is thought by himself to carry out approximate point marking, namely a Marker pen which is subjected to disinfection treatment is used for carrying out approximate point marking, so that the preparation effect of the scleral flap is seriously influenced.
The inventor has searched for the conventional scleral marking tool, but has found that there is no commercially available scleral marking tool product and no related patent for the scleral marking tool, which is why the conventional art still uses a simple Marker pen for writing to perform the operation.
