Description

Parallel Guidewire Introducer The present invention relates to a parallel guidewire introducer that secures a pathway for guidewire insertion through vascular puncture, and more specifically, to a parallel guidewire introducer that arranges introducer needles for vascular puncture and intravascular entry in parallel, thereby increasing the success rate of targeted vascular puncture through the insertion of introducer needles and guidewires, even if the operator's proficiency is low or ultrasound equipment is unavailable, and enabling the smooth execution of necessary interventional procedures. Introducer needles or guidewires are devices used in the medical field for interventional procedures. They enable examinations and treatments tailored to specific purposes by puncturing a patient's blood vessel and inserting specific medical devices into it. Using introducer needles and guidewires allows for safer access to the vascular lumen compared to not using them, and maintains access to the lumen even after the medical devices are inserted or removed. However, when the operator performing the puncture lacks proficiency or equipment such as ultrasound is unavailable, successfully performing the puncture is difficult; consequently, there were frequent failures in inserting the guidewire and securing access to the vessel lumen. This resulted in the inability to perform the intended procedure, leading to delays or failures in examinations and treatments, which in turn caused a worse prognosis for the patient. As a conventional device for vascular puncture, a steerable needle has been devised as disclosed in Korean Registered Patent Publication No. 10-1729150. However, in emergency situations where a guide wire must be inserted into the blood vessel quickly, the blood vessel could not be easily punctured with a steerable needle, and even if the needle is inserted into the correct desired position, there are cases where the blood vessel is pushed sideways and the puncture fails. Accordingly, there is a need for a device that can rapidly puncture blood vessels for guidewire insertion even when an operator with low proficiency performs the procedure or when ultrasound equipment is unavailable. The technology forming the background of the present invention is disclosed in Korean Registered Patent No. 10-1729150.
