Abstract

This article studied a novel connection method between the steel wire rope and the outer shell of a cobalt-60 afterloading brachytherapy source delivery whip. The performance requirements for the connection between the steel wire rope and the shell are described by analyzing the structural characteristics and usage environment of the source whip. Multiple joint forms and process ideas are proposed and explored. After repeated testing and improvement, a set of embedded adhesive bonding connection methods is finally proposed. The small-diameter cobalt-60 afterloading radiation source whip produced by this method meets the requirements of experimental verification and clinical use, effectively solving the problem of connection between the radiation source shell and steel wire rope.
