Title: Endoscopic surgical instrument with pivotable and rotatable staple cartridge
Inventor: SMITH JACK E
IPC: A61B1/00
Filed: 1994-06-20
Abstract: ABSTRACT OF THE DISCLOSURE      A surgical instrument is provided which is insertable through an endoscopic tube to enable a surgeon to perform a surgical technique inside a body cavity.  The surgical instrument includes a shaft with a pivotally mounted tip attached thereto, the shaft extending from a handle for gripping the instrument for insertion to the body cavity. The tip of the shaft is adjustable to different angular orientations relative to the support shaft and is rotatable at any angular orientation of the tip.  The support shaft may be rotatable about its longitudinal axis relative to the handle, or it may be fixed with respect to the handle, in which case the handle may be rotated to rotate the shaft inside the body cavity.  In one embodiment, the surgical instrument comprises an endoscopic stapling device and the tip of the instrument comprises a staple cartridge which is rotatable 360° about its axes after the cartridge has been articulated with respect to the support shaft.  An improved device for articulating the shaft tip is also provided in which a control knob is mounted to the support shaft for providing sweeping articulation of the shaft tip.  Separate actuator mechanisms are provided on the handle to control the pivotal movement of the shaft tip,  as well as the rotation of the shaft tip and the rotation of the support shaft.

Title: Optical Waveguide Multiplexer for Optical Fiber Amplifiers
Inventor: YOKOYAMA JUN
IPC: G02B6/34
Filed: 1994-06-30
Abstract: An optical waveguide multiplexer for use in optical fiber amplifiers or the like, which is simple in configuration, permits manufacturing at high productivity, and is reduced in size and moreover susceptible to little insertion loss, is to be realized.  A multiplexer-branching filter is provided with first to fourth input/output (I/O) terminals.  Part of an optical signal emitted from the first I/O terminal is reflected by a branching film, formed over one face of a glass plate, and led to the second optical I/O terminal.  The rest of the optical signal penetrates the glass plate, and further penetrates an optical multiplexing film, formed on the other face, to be led to the third optical I/O terminal.  The invention has a particular characteristic that the thickness t of the substrate is set so as to satisfy the condition of t ~ w/cos.theta. x tan [sin -1{(sin.theta.)/n}] where n is the refractive index of the substrate; w, the beam diameter of the output light of the optical I/O terminal for multiplexing the signal light with an pomping light; and .theta., the angle of incidence from this terminal to the substrate.  By setting the substrate thickness at or above the value stated above, the optical path of any leak light from the pomping light side is deviated from that toward the monitor side, and no pomping light can  enter into the monitor.  It is also possible, by adding an aperture film to the substrate, to further reduce the leak light.
