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.

Regional pain blocks are typically performed by the anesthesiologist under ultrasound guidance in the hours before (block room), in the operating suite, or after (post-op ro...

AI Technical Summary

Benefits of technology

[0006]Bolus and continuous drip regional nerve blocks are frequently used to mitigate painful sensations following joint surgery, including following total knee arthroplasty (TKA). In this case, the catheter tip for introducing nerve blocks is placed by an anesthesiologist nearby a nerve in 1 of 3 locations: 1. F

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
