摘要： A trocar includes a shaft having a leading section, a trailing section, a reduced diameter midsection located between the leading and trailing sections, and a longitudinal axis extending along the length of the shaft. The leading section of the shaft has a tapered region that terminates at a blunt tip. The trailing section of the shaft has a connector located at the trailing end thereof. The leading and trailing sections of the shaft having a first diameter and the reduced diameter midsection of the shaft has a second diameter that is smaller than the first diameter for enabling the shaft to be bent at the reduced diameter midsection. A flexible wound drain catheter having a first end is secured to the connector at the trailing end of the trailing section of the shaft. The flexible wound drain catheter has an outer diameter that matches the first diameter of the leading and trailing sections of the shaft.
