An endoscope having a guide tube is described herein. The assembly has an endoscope which is slidably insertable within the lumen of a guide tube. The guide tube is configured to be rigidizable along its entire length from a relaxed configuration. The endoscope has a steerable distal portion to facilitate the steering of the device through tortuous paths. In the relaxed configuration, a portion of the guide tube is able to assume the shape or curve defined by the controllable distal portion of the endoscope. Having assumed the shape or curve of the endoscope, the guide tube may be rigidized by the physician or surgeon to maintain that shape or curve while the endoscope is advanced distally through the tortuous path without having to place any undue pressure against the tissue walls.

A microsurgical instrument has a pair of operative surgical surfaces that are moved relative to each other in shearing or grasping procedures performed by the instrument. The instrument has a handle containing an elongate center rod with a ring mounted for reciprocating movement on the rod. A tube is secured to the ring and a shaft extends through the tube and is secured to the rod. The handle also includes a plurality of resilient arms that extend along the length of the rod and engage against a sliding surface of the ring on the rod. The plurality of actuator arms are alternatively manually compressed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the arms to flex radially inwardly and outwardly. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod and causes the tube and shaft to move axially relative to each other.

A surgical tissue ligation clip and an applicator device for delivery of multiple ligation clips is provided.

A safety ring binder mechanism helps prevent finger pinching by requiring simultaneous opposite movement of sliding actuators at both ends of the mechanism in order to open and close the rings. When the actuators are outermost, dimples on the actuators press the blades of the device against the housing, holding the rings open. When the actuators are pushed in, inclined tongues cam the ends of the blades downward, forcing the rings to close and holding them in a closed position.

A pair of capacitors are provided at a window sash or a window glass edge. Each capacitor is connected to two variable phase delay generators in parallel. Selectors are inserted between the capacitors and variable phase delay generators. Each selector alternates the connection between the capacitor and two variable phase delay generators. Upon insertion of human bodies, two variable phase delay generators reverse relative phase delays of the output signal from the two variable phase delay generators. If one of the relative phase delays is reversed, the human bodies are detected to be inserted into the window opening.
