1. A puncturing device, comprising: a handle connected with a puncturing needle; the handle comprises a proximal end handle part and a distal end handle part which are opposite to each other; the proximal end handle part comprises a proximal end handle shaft having an axial inner cavity and a proximal end handle ring connected to the proximal end handle shaft; the axial inner cavity of the proximal end handle shaft passes through a proximal end face and a distal end face of the proximal end handle shaft; the distal end handle part comprises a distal end handle shaft having an axial inner cavity and a distal end handle ring connected to a side wall of the distal end handle shaft; the axial inner cavity of the distal end handle shaft passes through a proximal end face and a distal end face of the distal end handle shaft; and the proximal end handle shaft is movably arranged in the axial inner cavity of the distal end handle shaft in a penetrating manner, and the distal end handle ring is closer to a proximal end of the puncturing needle than the proximal end handle ring;
wherein the proximal end handle ring is connected to a side wall of the proximal end handle shaft.
