AI Technical Summary

Technical Problem

The existing wire insertion and guidance methods lead to contamination of the doctor's hands, slipping of the wire guide, hanging the wire on the body of the medical staff and cutting the blood vessels.

Method used

The guide wire guide rub assembly is adopted, including a slider, a first throttle and a second throttle. The circular wheel is formed by clamping the guide wire, inserted into the catheter sheath along the guide base, and fixed the guide wire with a positioning pin, combining the blood guide shell to avoid blood contamination.

Benefits of technology

It avoids the mounting of the guide wire on medical staff and blood contamination, ensures that the guide wire is inserted into the blood vessels smoothly, prevents the blood vessels from being cut, and keeps hands clean.

Abstract

The present invention discloses a guide device for inserting a guidewire for cardiovascular interventional surgery, belonging to the technical field of guidewire guidance. The device comprises a guide seat, a guidewire guiding and twisting assembly comprising a slider, a positioning pin elastically and slidably inserted on the slider, a second dial rotatably connected to the slider, and the second dial elastically connected to the first dial; the guidewire is clamped by the first dial and the second dial, both of which are fan-shaped structures and form a circular wheel, and the guidewire is inserted into a catheter sheath along the guide seat through the reciprocating circular wheel; the first dial and the second dial are toggled and placed on the slider, and the circular wheel clamps the guidewire; the positioning pin is squeezed and inserted into the guide seat by the second dial, thereby preventing blood from flowing out of the catheter sheath and contaminating the doctor's hands, the guidewire, and the catheter sheath. The guidewire is inserted into the catheter sheath by the guidewire guiding and twisting assembly through the reciprocating movement of the guidewire stored in the guidewire storage tube, thereby preventing the guidewire from accidentally being pulled out of the catheter sheath and causing blood vessels to be scratched.
