Abstract
Description
Technical Field
[0001] The utility model relates to an abdominal exhaust device, in particular to disclose an abdominal exhaust device for full-thickness resection under digestive endoscopy. Background Art
[0002] During the process of full-thickness resection under digestive endoscopy, it is necessary to exhaust the patient's abdomen. The most commonly used exhaust tool at present is a common 20-ml syringe. 10 ml of normal saline is drawn, vertically inserted into the patient's abdomen, then the piston of the syringe is pulled out, and the syringe is temporarily fixed on the patient's abdomen with adhesive tape. If there are bubbles tumbling in the water in the syringe, it indicates that the exhaust is successful. The injection device is removed after the operation. By fixing the syringe with adhesive tape, the stability of the syringe is poor. At the same time, the vertically inserted syringe is not easy to fix, and the injection needle is easy to shake in the abdominal cavity and damage other organs. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the defects existing in the prior art and provide an abdominal exhaust device for full-thickness resection under digestive endoscopy with good stability, high safety, firm fixation and convenient operation.
[0004] The utility model is realized as follows: an abdominal exhaust device for full-thickness resection under digestive endoscopy, including a water storage device and a right-angle injection needle. The water storage device is in a horizontal column shape. The upper part inside the water storage device is a water storage cavity, and the bottom surface of the water storage cavity is an inclined surface with the front lower and the rear higher. An air inlet is arranged at the lower part of the front end of the water storage cavity. A syringe connector connected to the air inlet is arranged at the front end of the water storage device. A water injection port communicating with the water storage cavity is arranged on the top surface of the tail of the water storage device, and a sealing cover is arranged on the water injection port.
[0005] The right-angle injection needle includes a fixed seat, a handle and a right-angle needle. The right-angle needle is formed by connecting a needle head and a needle body that are perpendicular to each other. The needle body is fixed on the fixed seat. The handle is arranged at the top or both sides of the fixed seat. A needle head interface matching with the syringe connector is arranged at the tail end of the needle body.
[0006] A first sticker is arranged at the bottom of the fixed seat; both sides of the first sticker extend to both sides of the bottom surface of the fixed seat.
[0007] A second sticker is arranged at the bottom of the water storage device; both sides of the second sticker extend to both sides of the bottom surface of the water storage device.
[0008] The water storage cavity of the water storage device is a transparent container, and a volume scale is arranged on the outer surface of the water storage cavity.
[0009] The bottom surface of the water storage device is a plane or a concave arc surface.
[0010] The outer contour shape of the cross-section of the water storage device is rectangular, bow-shaped or crescent-shaped.
[0011] The handle is composed of a first sheet-shaped handle and a second sheet-shaped handle. The first sheet-shaped handle and the second sheet-shaped handle are symmetrically fixed on both sides of the top of the fixed seat. The plane where the first sheet-shaped handle is located forms an angle of 45 to 60 degrees with the horizontal plane.
[0012] A detachable plug is provided on the syringe connector.
[0013] The beneficial effects of the present utility model are as follows: Through the fixed seat, the handle and the right-angle needle, it is convenient to puncture the right-angle needle into the patient's abdomen. After puncture, the fixed seat is fixed on the patient's abdomen to prevent the displacement of the right-angle needle; the right-angle setting of the right-angle needle can prevent the obstruction of the line of sight during puncture, facilitating puncture and holding. Due to the bottom surface of the water storage cavity of the water storage device being an inclined surface that is lower in the front and higher in the rear, the water in the water storage cavity automatically gathers at the front end of the water storage cavity, facilitating the observation of the bubble tumbling situation of the water in the water storage cavity.
