[0017] 1. The utility model proposes an adjustable auxiliary distraction device. For a straddling esophageal foreign body, the distraction device is delivered to the distal end of the foreign body through a gastroscope, and then air or water is pumped into the inner wall of the air bag of the device through a gas supply hose so that the air bag on the inner wall of the device bulges and presses against the esophageal wall (the esophageal wall near the foreign body) to loosen or fall off the foreign body, making it easier to remove the foreign body. Alternatively, during an endoscopic operation, the distraction device is inserted through a digestive endoscope, and then water or steam is injected into the device through a gas supply hose. The relative position of the device in the digestive tract is changed by the traction of gravity or the pulling action of a traction tube, making it easier to perform the operation. Alternatively, the digestive tract is temporarily closed to facilitate inflation of the surgical area to expand the digestive tract and make it easier to perform the operation.
[0018] 2. The utility model proposes an adjustable auxiliary expansion device, which can supply air or inject water to the inner wall of the airbag through the air supply hose on the inner wall of the traction tube, and realize the expansion function by making the airbag swell. In addition, the device pulls the upper plate through the traction tube, so that the upper plate drives the airbag to achieve a vertical and horizontal state, making the expansion mechanism more convenient to adjust, and a bracket is provided inside the airbag, which makes the airbag more durable.
