Description

Spliced leading-in head

Technical Field

The utility model belongs to the technical field of leading-in heads, and particularly relates to a spliced leading-in head.

Background

An intraocular lens is an artificial lens that is placed in the posterior chamber of the eye (between the iris and the anterior surface of the natural lens) by implantation surgery to improve the patient's post-operative corrective vision. The morphology of an intraocular lens is typically composed of a centrally located circular optic and peripheral haptics. The artificial lens is classified into a hard artificial lens having an optical portion made of a hard material such as PMMA, and a soft artificial lens having an optical portion made of a flexible material such as a silicone elastomer, hydrogel, or soft acrylate, due to the different materials of the artificial lens. Intraocular lenses made of soft materials are also often referred to as collapsible intraocular lenses.

When using a rigid intraocular lens, the surgical incision made in the cornea to implant the intraocular lens must be approximately the same as the optic diameter width. And an intraocular lens made of soft material (also often referred to as a foldable intraocular lens) may be implanted into the eye through a small incision (typically 2-3 mm) after being folded or rolled to reduce its area, and the folded or rolled intraocular lens may be automatically unfolded after entering the eye.

The splice type lead-in head and preassembled implantation system disclosed in Chinese patent application publication No. CN211067209U3 are detachably connected with the lead-in head, and the splice type lead-in head is convenient to use with the lead-in head body in a clamping manner:
