Abstract
Disclosed is an interventional instrument that is convenient to position, comprising a support (), wherein the support () is of a frame structure with a hollowed-out area () and is provided with an axis in space, and the support () has a loaded state, in which the support is radially compressed, and a released state, in which the support is radially expanded; a sealing film (), connected to the support (), and the position of which corresponds to at least part of the hollowed-out area, wherein in the loaded state, the peripheral face of the support () is enclosed to form a storage space, and the sealing film () is located in the storage space; and a friction increasing component () connected to the sealing film (). According to the interventional instrument, by arranging the friction increasing component () and improving the mounting position of the friction increasing component (), frictional positioning is provided, and adverse effects on loading are also avoided, such that potential safety hazards are eliminated as much as possible. Further disclosed are a corresponding machining method and an interventional system.
