Vena Cava Filter Grabber

Abstract

The invention relates to the technical field of medical equipment, and discloses a vena cava filter catcher, which includes a recovery tube, and a connecting tube is sleeved inside the recovery tube; The position mechanism is used to limit the position of the limit block, so that after the snare catches the hook of the pulse filter, it can lock the hook of the pulse filter at the bottom of the connecting tube, and locking the hook of the pulse filter can prevent the medical staff from pulling When taking it out, the hook of the pulse filter and the snare will be separated due to looseness, avoiding the need for medical staff to operate the hook of the pulse filter twice, shortening the patient's operation time and reducing the damage to the patient's veins. Tightening the hook of the pulse filter can also reduce the operation of the hook of the pulse filter by the medical staff, and prevent the medical staff from distracting the operation of the recovery tube and the connecting rod of the snare, which reduces the difficulty of the operation, and is more convenient and quick to use, and is extremely practical powerful.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vena cava filter catcher.
