Abstract: An insertion tool for inserting devices during a laparoscopic procedure includes a first housing comprising a joystick module and a circuit board, a second housing comprising a first pulley and a second pulley, an insertable device, a first jacket coupled to the first housing and the second housing, a second jacket coupled to the second housing and an articulating portion. The articulating portion comprises articulating segments. Each of the articulating segments includes a plurality of apertures through which a plurality of lines passes therethrough from the first and second pulleys to sockets located in the insertable device. Movements of the joystick module send signals through the circuit board to motors which displace the first and second pulleys. The displacement of the first and second pulleys ultimately displaces the insertable device via the plurality of lines. Movement of the lines moves the articulating segments in controlled, precise movements during laparoscopic procedures.

Abstract: An endoscope is described in which the diameter of the image relay assembly is less than that of the objective lens assembly. An endoscope sheath is also described for sheathing the endoscope and housing or directing optical fibers for use in illuminating the endoscope view of view. An endoscope-sheath system is further described comprising the combination of the endoscope and the endoscope sheath in eccentric alignment to reduce fluid flow impedance between the two.
