Provided is a stent to be inserted into an in vivo organ having a tubular structure that allows a degree of freedom in design and excellent mechanical flexibility. A cylinder-shaped stent is inserted to be placed and used in the inner cavity of an in vivo tubular organ, wherein: the wall of the stent has a planar mesh pattern filled with a plurality of closed cells being adjacent to each other and having congruent shapes; the closed cells have point-symmetric parallel hexagonal shapes; all closed cells circumferentially adjacent to each other are congruent and similar in shape; two closed cells adjacent to each other sharing different sides form a substantially V-shaped member; and the vertex of each folded part in the substantially V-shaped member points to the circumferential direction.

A bending-resistant and tensile elevator or lift travelling flexible fireproof cable comprises multi-strand soft copper wire conductors formed by twisting multiple strands of soft copper wires. A first synthetic mica tape layer is wound on the surface of each multi-strand soft copper wire conductor, and a ceramic silicone rubber insulation layer is arranged on the surface of each first synthetic mica tape layer through extrusion to form a fireproof insulated wire core. A plurality of fireproof insulated wire cores are stranded together, and a third refractory layer and a second synthetic mica tape layer wrap the stranded fireproof insulated wire cores to form a cable core. A plurality of cable cores are arranged in parallel to form a cable core group, multi-strand flexible steel wires are arranged between the cable groups, each multi-strand flexible steel wire is coated with a second refractory layer, and the gaps between the cable cores and between the cable cores and the multi-strand flexible steel wires coated with the second refractory layers are filled with glass fibers, so as to form a multi-group cable core. A first refractory layer and a third synthetic mica tape layer are arranged in a winding way, a metal welding corrugated armor layer is arranged in a longitudinal wrapping way and a ceramic silicone rubber outer sheath is arranged in an extrusion way outside the multi-group cable core in sequence.
