This application relates to the field of medical device technology, and in particular to a minimally invasive dilation and drainage kit, comprising a sheath body and a dilator. The dilator is fixedly and detachably assembled to the end of the sheath body. An annular groove is provided on the outer peripheral wall of the end of the sheath body near the dilator. A hemostatic ring assembly and a cooling ring assembly are disposed within the annular groove. Both the hemostatic ring assembly and the cooling ring assembly are connected to the control part of a minimally invasive surgical device via wires. The wires are either attached to the outer peripheral wall of the sheath body or pre-embedded inside the sheath body.
