APPLICATION OF WATER-ABSORPTION MATERIAL IN MEDICAL CAVITY CHANNEL EXPANDER

摘要

A medical cavity channel expander is prepared by water-absorption resin. The cavity channel expander has great improvements in terms of water-absorption capability and water-absorption speed, especially the water-absorption speed, so as to greatly reduce waiting time of a patient, and be applicable to expansion of all cavity channel surgeries. Moreover, the cavity channel expander has a surface with a hyper-slippery effect after absorbing water, so the cavity channel expander can enter the cavity channel smoothly without any lubricant.
