The adjustment knob is used to adjust the diameter of the corneal ring to exactly coincide with the patient's limbus.
The utility model discloses a cooperation that sets up cornea ring, needle file, pinhole and adjust knob is used, has changed the in-process of current vitreous chamber injection and has not dedicated operation appurtenance's current situation, reduces the operation degree of difficulty, reduces the operation complication, and this auxiliary device possesses the advantage of being convenient for to fix, easy popularization, and the practicality is strong.
The utility model discloses in, body structure is identical with the sphere of eyeball, and the cornea is located the corneal ring, and the corneal limbus is tangent with the corneal ring, and the cornea is fixed in the corneal ring, and the eyeball is static relatively, and the doctor is handheld special syringe, makes its syringe needle pass corresponding pinhole, directly pours into vitreous intracavity into, keeps accurate needle insertion angle, makes the operation simple and convenient safety more, and easy the popularization. The size of the corneal ring is properly adjusted by the adjusting knob according to the size of the cornea of a patient, so that the difference of patients with different sexes, infants, large corneas or small corneas and the like is solved, and the application prospect is very wide.
Compared with the prior art, the utility model the advantage be: the utility model discloses an advantage of product, the location is accurate, and is simple and convenient good-purpose, improves the security and the standardization of operation, even do not also can accomplish this operation smoothly under the microscope's of performing the operation the condition, and the basic unit of being convenient for is popularized.
