PUNCTURE GUIDER AND PUNCTURE GUIDING SYSTEM

摘要

Disclosed are a puncture guider (02, 2) and a puncture guiding system, wherein a puncture channel (80) automatically adapted to the diameter of a puncture needle (03) can be realized in the puncture guider (02, 2). The puncture guider (02, 2) is used for connecting to a puncture support, and the puncture guider (02, 2) comprises a depth block (21) and a push plate (22), wherein the depth block (21) comprises: a connection structure for being connected to the puncture support, and a first guiding wall (211) and a second guiding wall (212), which are connected to each other and form an included angle; and the push plate (22) comprises: a needle groove plate (222), and an adaptive component. A first end face (2221) of the needle groove plate (222), and the first guiding wall (211) and the second guiding wall (212) enclose a puncture channel (80), and under the action of the adaptive component, a displacement can occur between the first end face (2221) of the needle groove plate (222) and the first guiding wall (211) and second guiding wall (212), so that the puncture channel (80) can change automatically according to the specification of the puncture needle (03), thereby automatically adapting to puncture needles (03) with different needle diameter specifications. The puncture guiding system comprises a puncture support and a puncture guider (02, 2).
