A clip applier includes a shaft having a proximal end and a distal end. Further, the distal end of the shaft includes a flexible tool having at least two rails connected to each other by at least one jointed connection, and the at least two rails configured to rotate about the jointed connection. Additionally, a pair of jaws may be provided at a distal end of the flexible tool. Further, an actuator may be provided at the proximal end of the shaft to advance the surgical clip within the flexible tool.

Flexible clip applier

A clip applier for deploying a surgical clip includes an actuator having a flexible wire and a collet chuck coupled to a piston. Further, actuation of the piston in a forward direction towards a distal end of the clip applier advances the flexible wire in the forward direction.

Actuator and detachable connector of flexible clip applier

A clipping instrument for an endoscope is provided. The clipping instrument includes a flexible sheath and at least one clip assembly with a pair of openable and closable clipping arms. The clip assembly is arranged in vicinity to a distal end portion of the flexible sheath with the clipping arms closed. The clipping arms are configured to be protruded forward to open outside the flexible sheath and to be closed to clip onto a treatment object outside the flexible sheath. The clipping instrument further includes an operating wire, which is configured to be forwarded and retracted to operate the pair of arms to be opened and closed. The clip assembly includes a bendable portion, which corresponds to a position of a shaft to support the clipping arms. The clip assembly can be arbitrarily bended at the bendable portion.

Clipping instrument for an endoscopic surgical device

A clipping instrument for an endoscope is provided. The clipping instrument includes a flexible sheath, an operation wire, at least one detachable clip assembly, including a pair of clipping arms and a fastening ring. The clipping arms are configured to be projected forward to open outside the flexible sheath and to be closed to clip onto a treatment object outside the flexible sheath according to movements of the fastening ring. The clipping instrument further includes a sleeve formed to have a plurality of slits and a blade spring piece to be attached to the sleeve. The sleeve includes a plurality of blade springs, each of which is settled in one of the plurality of the slits of the sleeve when the blade spring piece is attached to the sleeve. The plurality of blade springs can resiliently hold the detachable clip assembly in a posture with respect to the flexible sheath.
