Abstract: A device for performing a transversus abdominis plane (TAP) block anesthetic injection during a laparoscopic surgical procedure. The device includes a handle, a needle fixed to the handle, and a sheath covering the needle. The sheath is slidably retractable via a thumb-operated slider on the handle. In a first position for device insertion, the sheath fully covers the tip of the needle, preventing the needle from puncturing any organ or tissue in the patient. In a second position, the sheath is retracted using the slider to expose the needle tip, enabling insertion of the needle tip into the appropriate tissue and injection of the anesthetic. The needle and sheath have a length suitable for reaching the desired abdominal location from outside the body through the laparoscopic port. A threaded luer and tube, fluidly coupled to the needle, are used to push the anesthetic through the needle and into the tissue.
