Lenticular nucleus supporter for cataract surgery

Abstract

The invention provides a lenticular nucleus supporter for a cataract surgery. The supporter is formed by an infusion handle, an infusion tube tail cover, an infusion tube, an infusion rod, a spring, an infusion tube cover, an infusion needle head and an infusion three-jaw. The infusion tube is hollowed, one end of the infusion tube is embedded into the infusion tube tail cover, the other end of the infusion tube is embedded into the rear end of the infusion tube cover, the front end of the infusion tube cover is in a cone shape, one end of the infusion needle head is embedded into the front end of the infusion tube cover, the infusion three-jaw is three thin steel wires, the tail end of each steel wire is fixed with the front end of the infusion rod, the spring is sleeved outside a front section of the infusion rod, a middle section of the infusion rod is adapted to the infusion tube in diameter, and the infusion handle is fixedly connected with the tail end of the infusion rod. According to the lenticular nucleus supporter, the infusion three-jaw is utilized to form a fan-shaped strut in an eye when the laceration of a posterior lens capsule occuring in an ultrasonic emulsification operation so as to support a downfallen nucleus, so that the operation is enabled to be carried out smoothly. The infusion needle head can also be used as an auxiliary hook, and the functions of chopping and rotating the nucleus can be played. The supporter has reasonable design, is simple and convenient to manufacture, adopts metal materials, can be disinfected at high temperature and high pressure, can be used repeatedly, and is low in cost.

Description

technical field [0001] The invention belongs to an ophthalmic surgical instrument, and relates to a microscopic instrument for ophthalmic phacoemulsification cataract surgery, in particular to a lens nucleus supporter for cataract surgery. Suitable for phacoemulsification cataract surgery. Background technique [0002] Cataract is the first blinding eye disease in the world and in my country, accounting for about 45% of all blinding patients. Cataracts cannot be prevented, but they can be successfully treated surgically to restore vision. [0003] It has long been recognized that cataracts occur due to clouding of the lens, which prevents light from entering the eye, and removal of the cloudy lens can effectively improve and restore vision. There were records of cataract acupuncture more than 1,000 years ago in my country and India. The modern intracapsular cataract extraction (ICCE) removes the cloudy lens completely from the eye. Since the posterior capsule of the lens ...

AI Technical Summary

Problems solved by technology

However, phacoemulsification cataract surgery has higher requirements for the operator, especially for beginners or those with a hard lens nucleus. If the phacoemulsification energy is not properly controlled during the operation, the posterior capsule of the lens is prone to rupture, and the lens nucleus falls into the vitreous cavity. series of serious complications
