Description

Cataract crystal crusher

The invention relates to a crystal crusher structure which can be applied to cataract surgery, in particular to a cataract crystal crusher.

When the crystal crystals become opaque due to the soluble protein gradually becoming insoluble protein for any reason, the blurred vision is called cataract; ageing aging is the most common cause, and other factors include diabetes, trauma, inflammation, and heredity.

Once the lens of the eye is gradually turbid, the vision is reduced, and finally the opaque white color prevents the light from entering the eye and the patient loses sight. So far, no drug therapy has been proven to effectively prevent or cure the cataract.

At present, cataract surgery is currently the only effective cure method. There are two kinds of surgery. One is "ultrasonocytic phacoemulsification and artificial hydrocrystal implantation". It is a small incision cataract surgery. It emulsifies and wicks the crystals with ultrasonic waves. It can be sutured or finger-slit 1 to 2 needles; the second is "extracapsular cataract extraction and artificial crystal implantation". The cataract is too mature. It is necessary to open a large wound to remove the entire crystal nucleus, so it is necessary to sew 6 to 7 needles; Special lenses or contact lenses should be added after surgery to correct the patient's vision.

In the surgical operation, when ultrasonic crystal emulsification is applied to remove the crystal crystal, it is necessary to pulverize the crystal grains to facilitate emulsification, so that cataract crystals for ocular surgery as disclosed in Patent Document 1 are used.
