Abstract: A surgical end effector includes a clevis and two jaws rotatably coupled to the clevis. A rocking pin in the form of a solid of revolution is pivotally supported by the clevis. The rocking pin may be pivotally supported by the clevis at the midpoint between the first and second ends.

The clevis may be coupled to an elongate shaft to provide an endoscopic instrument. The first and second jaws may be electrically isolated from one another for electrocautery and the rocking pin may be formed from a non-conductive material or electrically isolated from the first and second jaws by electrically non-conductive liners. The jaws may be opened and closed by pushing and pulling on wires coupled to the jaws.

Abstract: A slide slot type multi-arm clamp includes a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, a surgical operator applies an axial thrust and a pulling force to the handle to drive the control line to move, so as to open/close and lock the clamping portion. Moreover, side clamp arms and a clamp base in the clamping portion can be easily separated from the catheter or the spring tube to stay in a human body so as to achieve the functions of hemostasis and tissue suture. The side slot type multi-arm clamp can achieve the effect of minimizing the length of the instrument retained in the human body by the cooperation between the side clamp arms and the clamp base.

Abstract: Apparatus and methods for occluding hollow body structures, such as blood vessels, and for attaching tissue layers together by providing implantable elements on opposite sides of the structure or tissue layers and drawing the implants together to occlude the body structure and/or bring the tissue layers together. The implants are deliverable in a low-profile configuration and self-expand to an enlarged configuration. The implantable elements are delivered by transfixing the body structure, then releasing the implants on opposite sides of the anatomical structure to urge the layers together to effect an occlusion or attachment. The implants are configured to apply oppositely directed forces to opposite surfaces of the tissue layers at alternate, circumferentially spaced locations and may constrain the tissue in a serpentine pattern or in a direct clamping pattern. The implants grip the tissue in a manner that defines a pressure zone about the transfixion aperture that prevents leakage from the aperture.
