Adductor Canal Block Introducer

Abstract

An adductor canal block introducer for introducing a catheter and also administering an initial dose of local anesthetic. The adductor canal block introducer generally includes a cannula having an elongated body with a distal end, a proximal end, and a slot extending along the elongated body, the slot having two sides and a lower surface. It also includes a cannulated trocar positioned in the slot of the cannula, the cannulated trocar having a distal end and a proximal end, wherein the trocar includes a discharge proximate to the distal end, wherein an inlet and the discharge are in fluid communication with each other. The introducer also includes a catheter positioned in the slot, held in place by the cannulated trocar. The catheter may also be positioned by a grasper introducer that holds the catheter and also includes a discharge at its distal end through which an anesthetic can be administered.

AI Technical Summary

Benefits of technology

This patent describes a device called the Matthews Adductor Canal Block Introducer that helps surgeons to accurately and efficiently perform nerve blocks in a way that doesn't require ultrasonic or electrical guidance. This device can be used during joint surgery, such as total knee replacement, to help manage pain and provide better patient care in situations where anesthesia services are not available. By using this device, surgeons can avoid the need for a separate anesthesia procedure to place the catheter.

Problems solved by technology

Despite the surgeon's enthusiasm and skills, it is evident that surgeons may not have the tools on-hand to reliably and safely place catheters intraoperatively.

Similarly, the lack of a set of standardized tools can place a significant burden on the surgical staff and administration to compile and maintain the correct set of instruments to assure safe and reliable catheter placement.

Surgeons are often supplied with insufficient / incorrect instruments, causing misplaced and / or damaged catheters.
