Abstract

The invention discloses a lamellar cornea detacher, which comprises a first tweezer head, a second tweezer head, a first tweezer rod and a second tweezer rod. The first tweezer rod is hinged to the second tweezer rod, the first tweezer head is fixed to a hinge end of the first tweezer rod, and the second tweezer head is fixed to a hinge end of the second tweezer rod. The first tweezer head has thecurvature radius of 6.8-7.0mm, thickness of 0.8-1.0mm and arc length of 3-5mm. The second tweezer head has the curvature radius of 7.2-7.5mm, thickness of 1.0-1.2mm and arc length of 3-5mm. The lamellar cornea detacher has advantages that dimensions of the first tweezer head and the second tweezer head fit those of human eyes; openness between the first tweezer head and the second tweezer head iscontrolled by compression of the first tweezer rod and the second tweezer rod, lamellar cornea detaching is realized under the counteracting force, and convenience in operation, accuracy in opennesscontrol, high stability, high reliability and applicability to cornea detaching surgeries.

Description

technical field [0001] The invention relates to the field of eye surgery equipment, in particular to a lamellar corneal peeler. Background technique [0002] Lamellar keratoplasty is a partial-thickness corneal transplant. During the operation, only the diseased tissue in front of the cornea is resected, and then a part-thick transparent corneal donor is transplanted to repair the resected area. The chance of immune rejection after surgery is low. Clinically, it is commonly used in the treatment of superficial corneal opacity, corneal dystrophic opacity, keratoconus, superficial corneal infection, corneal tumor, etc. [0003] Lamellar keratoplasty can remove the lesions in time, the lesions can be treated thoroughly during the operation, the inflammation can be easily controlled, the eyeball can be preserved, and conditions can be created for another vision-enhancing keratoplasty. The operation does not need to cut the anterior chamber, and postoperative complications suc...
