Abstract：This article was intended to carry out the study and discussion with regard to the problems as
well as solutions in the process of using HYG TC-I type thermo chemical ablation system for the precise
injection control of the alkali metal ablation agents. Until now, the general standard of precision injection
pumps has not been clearly defined, and the flow accuracy of most such products are in the range of
5%~20%. However, the alkali metal ablation dosage is microliter grade, such a large error will lead to a
less accurate control in ablation reaction. Via the optimized design of the storage scheme and the drive
structure, the accurate intensity and extent of alkali metal ablation can be achieved in order to ensure
the safety and effectiveness of the thermo chemical ablation therapy. Through the theoretic calculation
and measurement, the injection accuracy of thermochemical ablation system for HYG TC-I type can be
controlled within 2%. Therefore, the precise control of the alkali metal ablation agents can be realized,
which provides the basic conditions for the realization of alkali metal ablation therapy.
