Integral lacrimal passage intubation guidance system

Abstract

The invention relates to an integral lacrimal passage intubation guidance system used for the operative treatment of child obstruction of the lacrimal passage, and has the advantages of safe technology, definite curative effect and extremely small side effect. As a brand new operation mode, the guidance system connects a polypropylene soft guidance system with a diameter of 0.4 millimeter and a hollow silicone tube with a diameter of 0.64 millimeter so as to form a unique lacrimal passage guidance and intubation system together with a special stainless steel hollow funnel type probe of which the middle part has a rail of 0.3 millimeter. The guidance system is provided with a special steel hook for hooking up the silicone tube in the lacrimal passage simultaneously. With smooth connection of a lacrimal passage soft guiding thread, the soft silicone tube in the lacrimal passage can be inserted into the lacrimal passage easily. The specifically designed intubation device can finish the lacrimal passage probing and the implantation of the lacrimal passage silicone tube synchronously, and avoid the damage to the lacrimal passage caused by a plurality of probing. The integral lacrimal passage intubation guidance system has the unique lacrimal passage soft guidance system, an integrally connected silicone tube design system, and a specific funnel type lacrimal passage hollow probe which can withdraw from the soft guidance system, thus the combination of the three systems is applicable to lacrimal passage intubation operative treatment on underage children.

Description

Technical field [0001] The invention relates to an operation treatment for children's lacrimal duct obstruction, and is especially suitable for young children with lacrimal duct obstruction. Background technique [0002] At present, congenital lacrimal duct obstruction is a common eye disease in infants and young children, and its incidence rate is as high as 6%. [1-3] . Lacrimal duct intubation is one of the commonly used methods to treat lacrimal duct obstruction. In China, the metal guide system is usually introduced into the nasal cavity. This method causes great damage to the lacrimal duct, is not easy to operate, cannot elastically expand the lacrimal duct, and is inconvenient to pull the silicone tube during the operation. Due to the current shortage of lacrimal duct intubation for infants and young children in China, the inventor invented an integrated lacrimal duct guiding and intubation system to solve the above problems. Its advantages are: 1. The metal guide s...
