A medical instrument, such as a surgical device for manipulating and placing a tissue suture and methods of using the same is disclosed. The device comprises a handle, a hollow shaft removably coupled to the handle assembly and a stylet extending within the hollow shaft and longitudinally slideable therein. Preferably, the stylet is not rotationally moveable relative to the shaft. The stylet may be moved between a first position wherein a grasping member formed on the stylet is retracted into a distal end portion of the shaft and a second position wherein the grasping member extends distally beyond the distal end portion of the shaft. Distal movement of an actuation member on the handle correspondingly moves the stylet to the extended position and movement of the actuation member to a proximal position on the handle correspondingly moves the stylet to the retracted position. Lateral movement of the actuation member on the handle does not impart rotational movement of the stylet relative to the shaft.
