Catheter assistor for intervene through radial artery

Abstract

The invention discloses a catheter assistor for intervene through radial artery, which is used to guide the instrument through abnormal paths, guide the instrument into the blood vessel or increase the torque control of catheters in the intervene through radial artery therapy; the device comprises a head end, a body part, a transition section, a push rod, a lock lever and a tail handle. the head end is tapered; the body part is cylindrical; the transition section is slanting streamline and gradually transitions to the push rod; a quick exchange hole is arranged in the middle of the transitionsection; the head end, the body part and the transition section are hollow, and there are opaque X-ray marks near the end hole and the two ends of the body part; the push rod is a stainless steel hypotube; the locking rod is a cylinder presets different grooves for easy locking with the guide wire and the catheter end; the end handle is flat, which is good for the operator to control; the surfaceof the instrument is coated with a super-slip coating. The catheter assistor for intervene through radial artery is designed according to the anatomical features of the intervene through radial arterytherapy, which can effectively improve the safety of the interventional procedure and the success rate of the approach.

Description

technical field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a transradial artery interventional catheter assisting device for guiding an instrument through an abnormal path, guiding the instrument into a blood vessel or increasing the twist control of the catheter during transradial artery interventional treatment. Background technique

[0002] Compared with the transfemoral approach, the transradial approach has the advantages of a lower incidence of vascular-related complications and no need for bed rest. According to literature reports, more than 90% of domestic coronary interventional operations are completed through the radial artery approach, and the radial artery approach has become the preferred approach for coronary interventional treatment techniques.

[0003] Anatomical variations of the radial artery are common, such as hypoplasia, ring, tortuous, high origin, etc. In addition, the radial artery is prone ...
