AI Technical Summary

Technical Problem

Existing vascular intervention methods face challenges in precisely remotely controlling surgical tools to navigate through complex blood vessel structures with multiple branches and bends, leading to potential delays and damage during insertion.

Method used

A vascular intervention master device with an operating rod capable of translational and rotational movements, equipped with measuring units to generate remote control signals for a slave device, and a control unit that provides various operation modes such as screw motion, leader and follower, tip sync, vibration, and anti-stall jumping to facilitate smooth tool insertion.

Benefits of technology

Enables precise remote control of surgical tools, allowing them to navigate through difficult vascular sites efficiently, minimizing damage and improving intervention efficiency.

Abstract

A vascular intervention master device is provided. The vascular intervention master device is operated by a surgeon and may include: an operating rod that is capable of translational and rotational movements; a rotating part into which the longitudinal tip of the operating rod is inserted, and which has a guide hole inside that longitudinally guides the translational movement of the inserted operating rod and which is linked to the rotational movement of the inserted operating rod; a first measuring unit connected to one longitudinal side of the operating rod that is exposed outside the rotating unit, which measures a physical quantity of the translational movement of the operating rod such that when the operating rod is performing a translational movement, a remote control signal provided to a slave device that drives a surgical tool inserted into the body is generated based on the translational movement of the operating rod; and a second measuring unit connected to the rotating unit, which measures a physical quantity of the rotational movement of the operating rod such that when the operating rod is performing a rotational movement, a remote control signal provided to the slave device is generated based on the rotational movement of the operating rod.
