Abstract

The invention discloses a respiration tracking and positioning needle which comprises a catheter and an adhesion excitation unit. Wherein the far end of the catheter is provided with a needle; the catheter further comprises an adhesion section and a flexible catheter, and the needle head, the adhesion section and the flexible catheter are sequentially distributed from the far end of the catheter; the adhesion excitation unit is configured to perform adhesion excitation on the adhesion section after the catheter moves to a preset position of the to-be-treated tissue, so that adhesion positioning occurs between the adhesion section and the to-be-treated tissue. According to the invention, the relative position between the needle head and the to-be-treated tissue is fixed in an adhesion positioning mode, and the optimal synchronization state between the positioning needle and the focus can be achieved no matter the positioning needle is used for puncturing or passing through a natural orifice.

Description

technical field

[0001] The invention relates to the technical field of puncture, in particular to a breathing tracking positioning needle. Background technique

[0002] In recent years, image-guided puncture biopsy of various organs, tumor ablation and radioactive seed implantation are often used in clinical diagnosis and treatment. The field of interventional therapy has risen rapidly, and has become a recognized and effective means of interventional diagnosis and treatment of tumors, and its clinical application is becoming more and more extensive.

[0003] One of the unavoidable motion problems faced when performing chest and abdominal scans is breathing motion. How to overcome the unstable position of the target area caused by respiratory exercise is the first problem to be considered in chest and abdomen scans. Respiratory gating technology is the best solution to this problem.

[0004] Respiratory gating technology is a technology to control or track the deviation c...
