The present invention is a device and method of using a variety of laparoscopic or NOTES surgical tools at a confined or inaccessible space, e.g., an intra-abdominal surgical and NOTES tool inserted through a single incision through the skin or hollow viscus. Generally, the laparoscopic or NOTES surgical devices include a device body having a first side and a second side, wherein the first side includes a positioning mechanism and the second side includes one or more of a variety of laparoscopic or NOTES tools.

A surgical instrument comprises a first elongated member and a second elongated member, the first elongated member and the second elongated member being operatively connected and configured to rotate in opposite directions to substantially limit counter torque. The first and second elongated members are flexible shafts. The surgical instrument can be configured to apply fasteners to a tissue portion. This embodiment of the surgical instrument includes a cartridge having a plurality of fasteners, an anvil, said anvil and cartridge being relatively movable between spaced and approximated positions, and a sled disposed in the cartridge. The sled includes a cam member. The cam member is designed to drive the fasteners through tissue and toward the anvil.

A duel lumen catheter is provided for use in minimally invasive surgery. The catheter generally includes a first tube defining an operative lumen and a second tube terminating proximally of the first tube and defining an inflation lumen. In one embodiment, the first and second tubes are concentric. In an alternative embodiment, the first and second tubes are separate and extend parallel to each other. The first and second tubes are provided with inflation ports adjacent their respective distal ends. There is also provided a method for performing minimally invasive surgery by inserting the catheter through the esophagus of a patient, insufflating the stomach and performing a surgical operation through the catheter and external to the stomach.

The present application provides a transverse stapler for intraluminal surgery, comprising a control member, a clamping push rod assembly, a positioning needle push rod assembly, a positioning needle driving assembly and a clamping driving assembly, and the positioning needle push rod assembly is sleeved on the clamp Holding the outside of the push rod assembly, the positioning needle push rod assembly and the positioning needle drive assembly are rotatably connected, and the positioning needle push rod assembly and the positioning needle drive assembly are axially relatively fixed and rotate relative to each other, clamping the push rod assembly and the clamp The holding and driving assembly is connected in rotation, and the axial direction between the clamping push rod assembly and the clamping driving assembly is relatively fixed and the two rotate relative to each other, and the control member drives the clamping push rod assembly to rotate to make the clamping member rotate relative to the clamping driving assembly, And the control member drives the positioning needle push rod assembly to rotate through the clamping push rod assembly, so that the positioning needle rotates relative to the positioning needle driving assembly. The steering of the end of the stapler is driven by the rotating control member, which is convenient for the operator to control the steering of the end without the hand-held handle part being rotated, and is convenient to use.
