Embodiment Construction

[0026] refer to Figure 1 to Figure 6 As shown, a compound phacoemulsification lens multi-layer chopping hook of the present invention includes a handle 1, a recess 4 is arranged on the side wall of the middle part of the handle 1, and the two recesses 4 are respectively located on both sides of the cutting edge of the chopping knife 3b. The two recesses 4 can make it more comfortable for the operator to hold; on the handle 1 on both sides of the recess 4, a number of anti-slip rings 5 ​​are arranged at intervals along the length direction. It can not only play the role of anti-slip but also make the grip more comfortable.

[0027] One end of the handle 1 is provided with a first hook 2, and the first hook 2 is composed of a first connecting rod 2a and a splitting needle 2b vertically arranged at the free end of the first connecting rod 2a; the first connecting rod 2a is V-shaped. Shaped structure and the included angle of the V shape is 120°. The splitting needle 2b has a c...

Abstract

The invention discloses a composite cataract ultrasonic emulsification crystalline lens multilayer nucleus chopping hook and belongs to the technical field of nucleus chopping hooks. The nucleus chopping hook is characterized by comprising a handle. A first hook part is disposed at one end of the handle, and a second hook part is disposed at the other end of the handle. The second hook part comprises a second connecting rod, a nucleus chopping cutter vertically disposed at the free end of the second connecting rod and a plurality of auxiliary cutters which are disposed on two sides of the blade of the nucleus chopping cutter at intervals and along the length direction of the nucleus chopping cutter, wherein the central line of the second connecting rod and the blade of the nucleus chopping cutter are located on the same plane; the auxiliary cutters located on two sides of the nucleus chopping cutter are in one-to-one correspondence and form a V shape, and the blades of the corresponding auxiliary cutters are opposite. The composite cataract ultrasonic emulsification crystalline lens multilayer nucleus chopping hook for treating cataract is ingenious in structure, flexible to use and good in effect.

Description

technical field [0001] The invention relates to a core chopping hook, and more specifically relates to a composite multi-layer core chopping hook for phacoemulsification of a lens. Background technique [0002] In the field of surgery in recent years, how to apply the concept of minimally invasive surgery throughout all surgical procedures has become a hot spot of concern. Cataract phacoemulsification technology is constantly being updated and matured. It has become a routine surgical method for cataract treatment and has been gradually transformed into refractive surgery. How to minimize the surgical incision, reduce the ultrasonic energy, shorten the operation time, reduce the loss of corneal endothelial cells and tissue damage, improve the operation efficiency, and obtain the best postoperative vision as early as possible under the premise of ensuring the safety of the operation is an important issue for all ophthalmologists. The goal pursued by the surgeon. The choppin...
