Guide wire recovery catheter for interventional operation and application thereof

Abstract

The invention discloses a guide wire recovery catheter for interventional operation and an application thereof. The guide wire recovery catheter comprises a catheter body and a straight sheathing canal sleeving on the catheter body, wherein the catheter body is made from a flexible material and is provided with a near end tubular structure and a far end flared structure connected to each other; the far end flared structure is configured such that when the straight sheathing canal shrinks, the far end flared structure extending out of the straight sheathing canal is unfolded outward through a self-recovery force. The catheter can be used for recovering guide wires, and can recover far end guide wire reversely smoothly in interventional operation, so that the problem of operation failure asthe guide wire cannot enter a positive catheter to establish a guide ware path when the far end artery is punctured reversely is solved, and meanwhile, a lot of time and vigor wasted for re-establishing the guide wire path are avoided, so that the X ray exposure time of doctors and patients is reduced.

Description

technical field [0001] The invention relates to a guide wire recovery catheter for interventional surgery, belonging to the technical field of vascular interventional medical devices. Background technique [0002] Endovascular treatment is the current development direction for the treatment of various arterial diseases. With the development of interventional technology and equipment, endovascular treatment of peripheral arteries has become the mainstream surgical method. [0003] For vaso-occlusive diseases of the lower extremities, the reverse puncture technique has become a common technique for the treatment of complex lesions, but due to the limitations of existing equipment, it is very difficult for the retrograde guide wire to enter the forward catheter. It is 4-5Frech thickness), which is quite different from the diameter of the blood vessel. It often takes a long time of repeated attempts to send the distal retrograde puncture guide wire into the forward catheter and ...

AI Technical Summary

Problems solved by technology

[0003] For vaso-occlusive diseases of the lower extremities, the reverse puncture technique has become a common technique for the treatment of complex lesions, but due to the limitations of existing equipment, it is very difficult for the retrograde guide wire to enter the forward catheter. It is 4-5Frech thickness), which is quite different from the diameter of the blood vessel. It often takes a long time and repeated trials to send the distal retrograde puncture guide wire into the forward catheter and establish a guide wire channel

If the guidewire channel cannot be established, the procedure fails

But at present, there is no catheter specially used to collect the guide wire, which makes the operator feel powerless and affects the operation and quality of the operation.
