  • Publication number: 20240285269
    Abstract: A procedure tool module for a vascular intervention procedure device is provided. The procedure tool module is coupled to a platform, which transfers at least one of a catheter, a guide wire, a micro catheter, and a micro guide wire in a front and rear direction and generates rotation power for rotating the same about a rotation axis of the front and rear direction. The procedure tool module supports a procedure tool which is one of the catheter, the guide wire, the micro catheter, and the micro guide wire. The procedure tool module includes a module housing separably coupled to the platform, and a driven gear rotatably disposed in the module housing and coupled to the procedure tool. The driven gear is driven by the rotation power from the platform and rotates the procedure tool about the rotation axis.
