AI Technical Summary
In existing technologies, traditional syringes cannot evenly cover the corneal wound with medication, resulting in uneven drug distribution and drug accumulation, which affects surgical efficiency and safety.
A spray device simulating the arc-shaped structure of the human eyeball was designed and installed at the front end of the syringe. The spray device has multiple small spray holes inside, and the liquid is sprayed evenly in a mist. Combined with the L-shaped needle design, the spraying accuracy and uniformity are improved.
It achieves uniform coverage of the medication, reduces surgical time, improves surgical efficiency and safety, reduces the risk of cross-infection, and enhances the biomechanical stability and healing speed of the cornea.
