Application of ultrasonic emulsifier in the medical field
Ultrasonic emulsifier is the process of using ultrasonic energy to mix two (or more than two) immiscible solutions uniformly to form a dispersion system, where one liquid is evenly distributed in the other liquid to form an emulsion.
Ultrasonic emulsifier is suitable for many industries:
1. Biological industry: natural pigment extraction, polysaccharide extraction, alkaloid extraction, oil extraction.
2. Chemical industry: ultrasonic gel liquefaction, resin defoaming.
3. Laboratory applications: cell crushing, material dispersion and aggregation.
4. Water treatment industry: polluted water is degraded.
5. Food and cosmetics industry: liquor is refined, and nano particles are produced.
In medicine, ultrasonic emulsifier is used to treat cataract. Ultrasonic emulsifier is used to smash the lens nucleus with ultrasound through a 3-5mm cornea or scleral incision to make it chylo-like, and then suck out together with the cortex. After the operation, the posterior lens capsule is retained and the posterior chamber intraocular lens can be implanted at the same time.
Cataract phacoemulsification Compared with traditional cataract surgery, phacoemulsification has better surgical results and has become an internationally recognized advanced and reliable cataract treatment method.
Features of ultrasonic emulsifier for cataract:
1. Better vision recovery and lighter postoperative response.
2. Postoperative astigmatism is small, and it is more conducive to correct or control postoperative astigmatism.
3. the operation time is short, the incision is small, and the pain is light; the light damage that may be caused to the retina is reduced, and surface anesthesia can also be considered in cases with conditions.
4. The surgical trauma is small and the postoperative recovery is quick; the postoperative drug dosage is small and the time is short; the chance of iris injury during the operation is reduced, and the conjunctival and scleral scars are reduced.
5. Surgical control is better, safety is improved, and complications are reduced; it is easy to maintain a deep anterior chamber during the operation, and the probability of posterior capsule injury and cortical remnant is reduced; intraocular lens implantation is safer and more reliable; closed surgery can maintain vitreous pressure Better, it is safer to deal with once complications occur, and the degree of control is better; the incidence of complications such as cystoid macular edema is reduced.
6. There is no need to wait for the cataract to mature before the operation can be performed, which avoids all the inconvenience and pain in the long waiting process and improves the quality of life.
