A clip applier for deploying a surgical clip, the clip applier comprising an actuator having: a flexible wire adapted to be connected to an actuating mechanism configured to reciprocate linearly in a backwards and foward direction, and a piston, wherein actuation of the piston in a forward direction towards a distal end of the clip applier advances the flexible wire in the forward direction, and a collet chuck coupled to the piston, wherein a proximal end of the flexible wire is positioned within the collet chuck and characterized by a collet chuck ring at a circumference of a distal end of the collet chuck, the collet chuck ring configured to apply a clamping force to the distal end of the collet chuck so as to clamp the proximal end of the flexible wire within the collet chuck, and a tube push configured to operate a distal end of the clip applier, wherein the collet chuck ring is positioned within a slit of the tube push; the slit having a front end engagement surface; and when the collet chuck is advanced in the forward direction, the collet chuck ring advances with the collet chuck until the collet chuck ring engages the front end engagement surface of the slit, and a valve positioned intermediate the proximal end and a distal end of the flexible wire in an axial direction of the clip applier and positioned within the tube push and press-fitted within an opening of an inner coil pipe, and the inner coil pipe being rotatably coupled to a rotator provided at a proximal end of the clip applier, wherein, when the collet chuck returns in a rearward direction towards the proximal end of the clip applier, the collet chuck releases the flexible wire such that the flexible wire is generally stationarily supported within the valve relative to the valve. a flexible wire adapted to be connected to an actuating mechanism configured to reciprocate linearly in a backwards and foward direction, and a piston, wherein actuation of the piston in a forward direction towards a distal end of the clip applier advances the flexible wire in the forward direction, and a collet chuck coupled to the piston, wherein a proximal end of the flexible wire is positioned within the collet chuck and characterized by a collet chuck ring at a circumference of a distal end of the collet chuck, the collet chuck ring configured to apply a clamping force to the distal end of the collet chuck so as to clamp the proximal end of the flexible wire within the collet chuck, and a tube push configured to operate a distal end of the clip applier, wherein the collet chuck ring is positioned within a slit of the tube push; the slit having a front end engagement surface; and when the collet chuck is advanced in the forward direction, the collet chuck ring advances with the collet chuck until the collet chuck ring engages the front end engagement surface of the slit, and a valve positioned intermediate the proximal end and a distal end of the flexible wire in an axial direction of the clip applier and positioned within the tube push and press-fitted within an opening of an inner coil pipe, and the inner coil pipe being rotatably coupled to a rotator provided at a proximal end of the clip applier, wherein, when the collet chuck returns in a rearward direction towards the proximal end of the clip applier, the collet chuck releases the flexible wire such that the flexible wire is generally stationarily supported within the valve relative to the valve.
