Vascular interventional catheter and device, and contact force detection method and detection device

Abstract

The invention provides a vascular interventional catheter and device, and a contact force detection method and detection device. The vascular interventional catheter includes a phase change material catheter, wherein the stiffness of the phase change material catheter changes according to a temperature change. The vascular interventional catheter includes a stress induction section and a stiffnessadjustment section, wherein the stress induction section is arranged at the top end of the phase change material catheter and intervenes into the blood vessel to acquire the contact force between thephase change material catheter and the blood vessel wall; and the stiffness adjustment section is connected with the stress induction section and used for adjusting the stiffness of the phase changematerial catheter. According to the vascular interventional catheter and device, and the contact force detection method and detection device, by arrangement of the stress induction section, the monitoring of the blood vessel wall contact force can be achieved, the stiffness of the vascular interventional catheter can be adjusted by arrangement of the stiffness adjustment section, and thus the safety in the intervention process is improved.

Description

technical field [0001] The present disclosure relates to the technical field of vascular interventional surgery, and in particular to a vascular interventional catheter, equipment, contact force detection method and detection equipment. Background technique [0002] In my country, the death of cardiovascular and cerebrovascular diseases accounts for the first cause of death among urban and rural residents. Minimally invasive vascular intervention surgery (endovascular intervention surgery), as an alternative to traditional thoracotomy, has been used in cardiovascular diseases for its advantages of small wound, good effect and quick recovery. It has been widely used in the clinical treatment of diseases. Traditional vascular interventional surgery refers to the process in which the doctor holds a special catheter guide wire, and with the assistance of real-time images, sends the catheter and guide wire from the puncture site into the blood vessel and continues to send it to th...

Problems solved by technology

[0006] Based on the above technical problems, the present disclosure provides a vascular interventional catheter, equipment, contact force detection method, and detection equipment, so as to alleviate the problem of using machine-assisted interventional surgery methods in the prior art, which cannot measure the contact force between the interventional catheter and the vessel wall. And the interventional catheter is relatively rigid, which is likely to cause technical problems of potential safety hazards
