Description
technical field [0001] The invention relates to a medical tool, in particular to a corneal foreign body scraping, collecting and cleaning system. Background technique [0002] The cornea is a transparent film at the front of the eye. The cornea is completely transparent, located in the front of the eyeball, and has a transverse oval shape. The cornea has very sensitive nerve endings. If a foreign object touches the cornea, the eyelids will involuntarily close to protect the eyes. [0003] In some cases, some foreign matter has entered the cornea. Generally, in the hospital, doctors often use the needle of the syringe to remove it. There is no tool specifically designed to remove foreign bodies from the cornea. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a corneal foreign body scraping, collecting and cleaning system. [0005] To achieve the above object, the present invention provides...
