A surgical instrument for fastening together opposing portions of a body organ. The instrument comprises a first support for supporting the first opposing portion of the body organ, a second support opposing the first support, for supporting the second opposing portion of the body organ, and a displacement-preventing member connected to the first or second support for preventing the supports from displacing relative to each other. The member comprises a pin protruding from one of the supports and a hole formed in the other of the supports. The pin is made of thermoplastic resin. When heated, the pin is softened and deformed, whereby the first and second supports are secured to each other, fastening together the opposing portions of the body organ.

Tissue-fixing surgical instrument, tissue-fixing device, and method of

A surgical manipulator system comprising at least one surgical manipulator, at least one guide, a detector, and a drive controller. The surgical manipulator has a surgical device for performing a desired operation. The guide guides the surgical device. The detector detects a position and/or orientation relationship between the surgical device and the guide, and/or a position and/or orientation relationship between the surgical device and another surgical device. The drive controller controls the surgical manipulator such that the surgical device is guided by the guide.

Surgical manipulation system

A stereoscopic endoscope including an objective lens system for forming an image of an object which objective lens system is arranged at the front end of an inserting section and has a single optical axis; an image transmission device coaxially arranged with the objective lens system and adapted to transmit the image formed by the objective lens system; a pupil dividing device for dividing the image transmitted through the objective lens system and the image transmission device so as to obtain left and right images of the object; an image sensing device for picking up the left and right images obtained by the pupil dividing device; a first support structure containing at least the objective lens system; and a second support structure containing at least the pupil dividing device and the image sensing device, wherein the first and second support structures are rotatable relative to each other around an axis extending along the longitudinal dimension of the endoscope.

Stereoscopic endoscope

A multi-degree-of-freedom manipulator includes a flexible tube having a plurality of flex portions provided therealong, a plurality of actuators made of shape memory alloy and respectively provided near the flex portions to correspond to the flex portions, for flexing the flex portions, two common energy transmission paths, extending along the flexible tube, for transmitting an energy to the actuators, and selective energy supply members, provided between the common energy transmission paths and the actuators in series, for controlling the energy supplied from the common energy transmission path to the actuators, thereby respectively independently driving the actuators to bend the flexible tube. The manipulator is made by forming electronic circuits in a plurality of regions on a semiconductor substrate, forming wiring regions to connect the electronic circuits with flexible wiring portions, and removing a region of the semiconductor substrate other than a region thereof on which the electronic circuits are formed, thereby forming an actuator controlled chip array, used in the manipulator.
