Abstract
Disclosed is an adjustable cryoablation needle, comprising a needle rod (), a front-segment heat-insulated tube (), a rear-segment heat-insulated tube (), and an gas inlet structure () penetrating the needle rod () and the front-segment heat-insulated tube (), wherein the needle rod () can move relative to the rear-segment heat-insulated tube () in the axial direction of the rear-segment heat-insulated tube () so as to adjust a first axial distance between the front end of the rear-segment heat-insulated tube () and the front end of the needle rod (); and the front-segment heat-insulated tube () can move relative to the rear-segment heat-insulated tube () in the axial direction of the rear-segment heat-insulated tube (). The adjustable cryoablation needle can prevent the inconvenience caused by a doctor selecting the model of the cryoablation needle.
