Title:
PUNCTURING DEVICE AND PUNCTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/041140
Kind Code:
A1
Abstract:
This puncturing device (1) has a puncturing section and an operation section. The puncturing section has: a curved section (713) curved in an arc; and a needle tip (351) that punctures in vivo tissue. The operation section has: a shaft section (73) provided on a rotating shaft (J1); and a coupling section (72) that couples the tip end of the shaft section (73) to the back end of the curved section (713). The arc center of the curved section (713) is on the rotating shaft (J1). The coupling section (72) and shaft section (73) are thicker than the curved section (713), and so the rigidity of the coupling section (72) and the shaft section (73) is greater than the rigidity of the curved section (713). When the shaft section (73) rotates by means of a handle (74), the curved section (713) rotates over a puncturing pathway (X) such that the curved section (713) has the rotating shaft (J1) as the center thereof, and the needle tip (351) punctures in vivo tissue. As such a time, although external force resulting from puncturing resistance is applied to the coupling section (72) and the shaft section (73), the coupling section (72) and shaft section (73) do not deform due to having high rigidity.
