Slave end controller of interventional operation assisting system with catheter-guide wire conducting collaborative operation

Abstract

The invention discloses a slave end controller of an interventional operation assisting system with catheter-guide wire conducting collaborative operation and belongs to the technical field of medical equipment.The slave end controller comprises a guide wire, a guide wire operator, a catheter, a catheter operator, a sliding bracket, an axial movement controller and a shell; the guide wire operator is used for conducting rotating, clamping and relaxing operation on the guide wire used for the operation; the catheter operator is used for conducting rotating, clamping and relaxing operation on the catheter used for the operation; the sliding bracket is used for supporting the guide wire and the catheter and limiting the movement locus of the guide wire before entering the catheter so as to prevent the guide wire from being bent before entering the catheter; the axial movement controller is used for controlling axial movement of the catheter and the guide wire; the shell is used for supporting the guide wire operator, the catheter operator and the sliding bracket.According to the slave end controller, interventional actions are completed according to operation information of doctors, real-time haptical information can be fed back to the doctor visually, and safety and operability of the interventional operation can be improved.

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
