In a bending tube for endoscope on which torsion preventing tab mechanisms are provided on the respective middle parts of first and second slots for bending located in an area from the proximal end of a bending tube body to a predetermined position on the distal end side (the torsion suppressing area), and the bending tube body being permitted to bend by the first and second slots for bending, the torsion preventing tab mechanism of at least any one of the first and second slots for bending arranged on the proximal end side of each of arrays (first and second arrays), other than the first and second slots for bending located at the most proximal end, among the first and second slots for bending arrayed in a same line, respectively, along a longitudinal direction of the bending tube body, is removed.

The present invention is an access sheath comprising a tube or sheath with a passageway primarily for endoscopic procedures accessing the ureter through the bladder. The sheath has a bend limiting feature to limit the bend angle or bend radius. The sheath exhibits flexibility up to this limit at which point it becomes rigid. Excessive force is required to bend the sheath beyond the bend limit and would result in the kinking of the tubular frame.

A resectoscope for endoscopic surgery, having a tubular shaft which includes an elongated sheath tube, and an irrigation tube arranged in the sheath tube for supplying irrigation fluid, as well as a rod-shaped lens and an electrode instrument, characterized in that the lens and the electrode instrument are arranged between the outer wall of the irrigation tube and the inner wall of the sheath tube. In addition, an electrosurgical system including the resectoscope and an irrigation fluid supply device.

A rigid endoscope for prostate biopsy includes: an insertion portion including a distal end portion including an ultrasound transmission and reception portion, and a bent portion bent at a predetermined curvature; a treatment instrument insertion channel that passes through inside the bent portion and includes a first opening portion provided on a distal end side and a second opening portion provided on a proximal end side; a shaft-shaped portion installed to extend in a proximal end direction of the bent portion along a straight line passing through an inflection portion provided between the distal end portion and the bent portion; and a grasping portion that includes the shaft-shaped portion.

Endoluminal robotic systems and corresponding methods include subsystems for visualization, navigation, pressure sensing, platform compatibility, and user interfaces. The user interfaces may be implemented by one or more of a console, haptics, image fusion, voice controls, remote support, and multi-system controls.

An operative cannula includes an elongate shaft that includes a wall structure and a channel extending along the wall structure. The wall structure defines an interior pocket sized to receive a tubular member and is configured to grasp the tubular member when the tubular member is disposed within the interior pocket. The channel is configured to allow passage of an instrument from a proximal end region of the elongate shaft through a distal end region of the elongate shaft.
