Abstract

The invention discloses a flexible puncture needle device, comprising a puncture needle, the puncture needle includes an outer sleeve and a central tube, and the central tube is inserted into the outer sleeve from the distal end of the puncture needle of the outer sleeve to form a central tube vacant part of the outer sleeve and inserted into the central tube The vacant part of the central tube can be bent. When the central tube moves forward or backward along the axis of the outer tube in the outer tube, the bending angle of the vacant part of the central tube changes with the length of the vacant part of the central tube. The flexible puncture needle device disclosed in the present invention can be applied to percutaneous puncture surgery, and can realize the adjustment of the bending angle and direction during the puncture process. The puncture needle device can be integrated into the surgical robot system, combined with medical imaging feedback, for Percutaneous surgery offers a flexible, precise solution.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a flexible puncture needle device. Background technique [0002] Puncture needle is an instrument used for percutaneous puncture interventional surgery. Compared with other surgical methods, puncture surgery can directly reach the patient site without exposing internal tissues and organs. It is easy to operate and is a minimally invasive diagnosis and treatment method. . [0003] Common puncture needles on the market, such as Seldinger needles and Chiba needles, are mostly slender and rigid structures. In the actual puncture process of this kind of slender rigid puncture needle, since it cannot flexibly bypass obstacles such as some important organs or tissues of the human body, its puncture process is difficult to control precisely. At the same time, the puncture needle itself is deformed, and the puncture needle is easy to deviate from the target. It is difficult ...
