The tractor lower part is provided with the terminal external screw thread of straight pole section, and the terminal external screw thread lower part of straight pole section is provided with the chamfer.
The tractor handle is cylindrical, and the diameter D of tractor handle is phi 25mm ~ phi 35mm, accords with the best diameter of holding of staff, and the tractor handle middle part is provided with handle internal thread hole, and handle internal thread hole upper portion is provided with the chamfer, and the tractor handle lower part is provided with convex afterbody.
The tractor is matched with a handle internal thread hole arranged in the middle of a handle of the tractor through external threads at the tail end of the straight rod section and is connected together through threads. The total length of the intestinal canal tractor is 200 mm-800 mm according to the difference of minimally invasive surgical operations under the endoscope.
The tractor is made of aluminum alloy materials.
The retractor handle is made of nylon materials.
The utility model discloses intestines tube tractor reasonable in design, compact structure, simple and practical adopts tractor, tractor handle to pull, part and lift the tissue at patient's abdominal cavity position to make intracavity cutting anastomat centre gripping to the best cutting of tissue more easily and sew up the position, reduce the operation incision, alleviate patient's misery, instrument when avoiding laparoscopic minimally invasive surgery alternately interferes, and very big extension operation field of vision shortens the operation time, provides convenience for doctor's operation.
