US 2026/0174416 A1 · Puncture Device and Puncture Method Thereof

Abstract

The application discloses a puncture device and a puncture method thereof. In the puncture device, a position limiting member is provided on the second member, and the position limiting member is used to limit the position of the first member, so that the first member can drive the second member to move toward the third member. The catheter is connected to the second member, so that the catheter can move together with the second member. The puncture needle is connected to the first member, so that the puncture needle can be driven to move when the first member moves, and the puncture needle can drive the catheter through the tissue together during puncturing. After that, the puncture needle can be withdrawn, and the catheter can be left in the tissue for subsequent surgical treatment, thereby reducing damage to the tissue during the operation.
