Catheter-guide wire cooperative operation interventional surgery assistance system slave controller

Abstract

The invention discloses a slave end controller of a catheter-guide wire cooperative operation interventional operation auxiliary system, belonging to the technical field of medical equipment; it includes: a guide wire, a guide wire manipulator, a catheter, a catheter manipulator, a sliding bracket, an Controller and housing; the guide wire manipulator is used to rotate, clamp and loosen the guide wire for surgery; the catheter manipulator is used to rotate, clamp and loosen the catheter for surgery; the sliding The stent is used to support the guide wire and catheter, and limit the movement track of the guide wire before entering the catheter, preventing the guide wire from bending before entering the catheter; the axial motion controller is used to control the axial movement of the catheter and guide wire The shell is used to support the guide wire manipulator, the catheter manipulator and the sliding bracket; the present invention completes the intervention action according to the doctor's operation information, and can intuitively feed back the real-time tactile information to the doctor, which can improve the efficiency of the interventional operation. safety and operability.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a slave-end controller of a catheter-guide wire cooperative operation interventional operation auxiliary system. Background technique [0002] Cardiovascular system disease is the most common type of disease in human beings. It is a major cause of death of the world's population and poses a serious threat to human health. Vascular diseases mainly include vascular tumors, thrombosis, vascular malformations, vasoconstriction, and vascular sclerosis. Vascular minimally invasive interventional surgery is a medical surgery mainly used for the diagnosis and treatment of cardiovascular and cerebrovascular diseases. Under the guidance of medical imaging equipment, with the help of interventional catheters along the lumen of blood vessels to reach distant lesion parts, such as coronary arteries, brain, liver and kidney blood vessels, and then perform minimally invas...

Problems solved by technology

Therefore, the experience and skills accumulated in traditional interventional operations are not well utilized and do not meet the requirements of ergonomics.

Moreover, in the actual operation, the doctor's operation must be frequent replacement or simultaneous operation of the catheter and guide wire.

In many studies, the design of the catheter operation robot device at the surgical site is based on the friction roller method, which is easy to cause damage to the catheter, and the damaged catheter may also cause damage to the blood vessel. At the same time, there is a propulsion error in the friction push itself

And there is no function of operating the catheter and guide wire at the same time
