Endoscopic medical device for tissue hemostasis or closure
The patent US12070226B2 describes a medical device designed for tissue hemostasis or closure, specifically for use through an endoscope. The device features a handle, a sheath device attached to the handle, and a clamp device that includes a clamp base and at least two clamp arms. A control wire runs through the sheath and is movable in both distal and proximal directions, allowing for the opening and closing of the clamp arms. The clamp arms are connected to the control wire via a pivot pin, enabling the arms to open and close based on the wire's movement. Notably, the design includes exit-passages in the clamp arms that facilitate the uncoupling of the control wire after the clamp arms have closed, allowing for a secure yet reversible operation.
Further claims detail the structural components and functionalities of the device. The clamp arms can elastically or plastically deform when spread apart, and they are designed to lock into place using hooks that engage with a shoulder on the clamp base. The device also incorporates a guide pin and guide grooves that ensure coordinated movement of the clamp arms during operation. Additional features include side teeth on the clamp arms for enhanced gripping and a coupling head that aids in the pivotal connection of the clamp arms to the control wire. Overall, the patent outlines a sophisticated mechanism aimed at improving the efficacy and safety of endoscopic procedures involving tissue closure.
