Abstract
A pushing apparatus and conveying system for an interventional medical instrument. By covering a thermoplastic elastomer on the surface of a steel cable to form an overlay film, steel cable support is improved when guaranteeing the flexibility thereof so that it is difficult for the instrument to deviate from a predetermined position when conveying the instrument, the operation time is shortened, and the operation risk of patients is reduced. Meanwhile, in the conveying system, a sealing member is provided in an inner cavity of a hemostasis valve body to match the overlay film of the steel cable so that the distal end of the hemostasis valve body is isolated from the outside, and the release effect of the instrument can be assessed by radiography before the instrument is released from the steel cable in operation, thereby effectively reducing harm to patients.
