Surgical instrument having an integrated local anesthetic delivery system

摘要

A surgical instrument includes a handle portion having a distal end, a proximal end, and a substantially hollow body defining a valve chamber therein; a curved incising tube partially housed within the handle portion adjacent the handle portion proximal end, extending a predetermined distance from the handle portion, and in fluid communication with the valve chamber; a local anesthetic inlet tube partially housed within the handle portion adjacent the handle portion distal end, extending a predetermined distance from the handle portion, and in fluid communication with the valve chamber; a local anesthetic delivery actuator disposed on the handle portion, whereby the local anesthetic delivery actuator is selectively operative between opened and closed valve chamber positions.

1. A surgical instrument configured for locally delivering anesthetic while implanting a mechanism configured for treating female urinary incontinence, the surgical instrument comprising:
a handle portion having a distal end, a proximal end, and a substantially hollow body defining a valve chamber therein; a curved sling- and anesthetic-delivery tube partially housed within the handle portion adjacent the handle portion distal end, extending a predetermined distance from the handle portion, and in fluid communication with the valve chamber, and configured to:
form a path in the lower abdomen of a patient;move a sling through pelvic fascia and soft tissue of the patient; andposition the sling between the patient's urethra and vaginal wall; a local anesthetic inlet tube partially housed within the handle portion adjacent the handle portion proximal end, extending a predetermined distance from the handle portion, and in fluid communication with the valve chamber; a local anesthetic delivery actuator disposed on the handle portion, connected to a biasing member that is configured to move the local anesthetic delivery actuator to a return position, wherein the local anesthetic delivery actuator is selectively operative between opened and closed valve chamber positions; and an actuator guard disposed on the handle portion and configured to prevent inadvertent actuation of the local anesthetic delivery actuator; wherein the surgical instrument is configured to locally deliver anesthetic while assisting a surgeon with forming the path through, moving the sling within, and implanting the sling in, the patient's abdomen.
