Clipping is a surgical procedure performed to treat an aneurysm. If the aneurysm is intracranial, a craniotomy is performed, and afterwards an Elgiloy (Phynox) or titanium Sugita clip is affixed around the aneurysm's neck. Surgical clipping was introduced by Walter Dandy of the Johns Hopkins Hospital in 1937.
Articulating Steerable Clip Applier for Laparoscopic Procedures
A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

The present invention relates to a device for the non-surgical clipping of aneurysms. The invention also includes methods of use to treat aneurysms, including intracranial aneurysms. The aneurysm is clipped by positioning a wire comprising a shape memory alloy, pre-set to a mutually twisted conformation, on opposite sides of the neck of the aneurysm and causing the wires to twist around each other. Thus, the aneurysm neck is substantially closed. The resulting thrombosis in the aneurysm further excludes the aneurysm from blood flow and pressure.

The invention relates to a medical surgical clamp matched with an endoscope, in particular to a visible surgical clamp with an endoscope sheath used for taking the intrauterine device out from the uterus. The existing visible surgical clamp is used in the birth control surgery, for example in the surgery to take the intrauterine device out from the uterus with the endoscope. Due to the easy bleeding of the endometrium tissue, the lens of the endoscope is easily contaminated to dim the surgery view, and the device is inserted in and taken out repeatedly for flashing, therefore the surgery time is prolonged and the operation is complicated. After the improvement, the groove formed after the side by side arrangement of the endoscope sheath and the drive rod is also fixed with two flush pipes 15 and 17, wherein the open of one flush pipe faces the open of the endoscope sheath 10, and the open of the other flush pipe faces a clamp head 6. A surgical cannula is provided, and the water nozzle on the surgical cannula is communicated with a negative pressure source to absorb and remove the water of flushing. The improved surgical clamp provides clear surgery view, has compact integral structure and convenient operation, and can shorten the surgery time.
