Abstract

The present invention discloses a lens nucleus pre-splitting device suitable for a micro-incision cataract ultrasonic emulsification operation. A head end of the device and a connecting rod can come in and out of eyes from a 2-mm micro-incision. The lens nucleus pre-splitting device comprises a connecting rod, a middle of the connecting rod is hollow tubular, a Y-shaped double-channel structure isformed in the hollow tubular connecting rod, an elastic handle is arranged at a rear end of the connecting rod and comprises two elastic slices, one ends of the elastic slices are connected to a rodbody of the connecting rod, the other ends of the elastic slices are a movable end, a silk thread structure is arranged in the hollow tubular connecting rod, one end of the silk thread structure is connected to the movable ends of the elastic slice, and the other end of the silk thread structure is divided into two strands at the double-channel structure to form a ring-shaped ring sleeve. The lensnucleus pre-splitting device is convenient in operation and short in learning curve, can easily and completely split nuclei of cataract crystalline lens, especially the hard nuclei, also has little damage to intraocular tissues, greatly improves efficiency and safety of nucleus splitting and is beneficial to smooth proceeding of the subsequent ultrasonic emulsification operation.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical devices, in particular to a lens pre-chopping device suitable for micro-incision cataract phacoemulsification surgery. Background technique [0002] Cataract phacoemulsification surgery has become a standard procedure for cataract treatment and is widely used clinically. With the advancement of surgical equipment and technology, the surgical incision of cataract can be reduced to 2mm or less, which is more minimally invasive and allows faster postoperative recovery. However, micro-incision surgery will increase the difficulty and risk of hard nuclear cataract (nuclear hardness grade 4 and above). At present, the nuclear splitters commonly used in cataract surgery have greatly reduced the success rate and efficiency of hard core splitting, and the operation is difficult, requiring a certain learning curve, and it is easy to damage the intraocular tissue during the operation. In phacoem...
