Catheter Insertion Instruments

Abstract

A catheterization instrument is disclosed that enables single-handed catheterization into a patient's vasculature. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guide wire partially within the handle and the needle cannula, and a first actuator coupled to the handle and guide wire. A first actuator is moveable in a proximal direction relative to the handle to move the guidewire in a distal direction away from the handle, and is moveable in a distal direction relative to the handle so that the The guidewire is moved in a proximal direction toward the handle. The catheter insertion device may also include a needle support that stabilizes the needle cannula during insertion of the needle cannula into the patient.

Problems solved by technology

However, known catheter placement instruments typically require the use of two hands for inserting the guidewire and placing the catheter into the vasculature, which increases the risk of contamination, increases the risk of inadvertently damaging blood vessels due to involuntary tip movement , preventing continuous use of ultrasound from the point of skin penetration, vessel passage, lead insertion until the first distal end and tip of the catheter in the vessel are shielded, making the device less convenient to use
