Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular to a flushing device used in clinical thoracic surgery. Background Art

[0002] During thoracic surgery, the patient's chest cavity needs to be opened to remove foreign objects (tumors) in the patient's chest cavity. There will be bacteria, impurities, tissue debris and other substances in the incision site of the opened chest cavity and the wound surface where the foreign objects are removed. This requires a flushing device to flush the opening to separate the substances from the tissues and suck them away under suction to keep the incision and wound surface clean.

[0003] In order to protect patients to the greatest extent, the incision during surgery should be as small as possible. Existing flushing devices all spray cleaning fluid through vertical pipes. However, in the narrow space during surgery, it is difficult to change the direction and angle of the flushing fluid in the patient's chest cavity, resulting in incomplete flushing of the patient's surgical wound, affecting the patient's postoperative recovery effect. Therefore, we urgently need a flushing device for clinical thoracic surgery. Summary of the invention

[0004] The purpose of the present invention is to provide a flushing device for clinical thoracic surgery to solve the above-mentioned deficiencies in the technology.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clinical operation flushing device for thoracic surgery, comprising a handle sleeve, the inner wall of the handle sleeve is sleeved with a rotating tube, the top outer wall of the rotating tube is sleeved with a butt joint tube, a top end of the butt joint tube is fixedly provided with a pull-out tube, a top end of the pull-out tube is fixedly provided with an angle adjustment hose, the interior of the angle adjustment hose is embedded with equidistantly distributed metal adjustment rings, the inner wall of the metal adjustment ring is fixedly provided with equidistantly distributed fixing blocks, one end of each fixing block is provided with a stretching hole, and the stretching holes located on the same straight line are provided with a plurality of holes.

[0011] Preferably, the fixed cover is connected to a controller via a wire, and the controller is connected to a power plug.

[0012] S1: When the present invention is used, the liquid guide hose is connected to the output end of the infusion pump, and the flushing liquid is input into the rotating tube through the infusion pump. The physiological saline in the rotating tube moves to the nozzle through the inner wall of the docking tube, the pulling tube and the angle adjustment hose. The operator holds the outer wall of the handle sleeve and sprays the physiological saline through the nozzle to flush the wound and incision, and cooperates with the washing device to suck out the flushing liquid;

[0013] S2: When the cleaning angle of the nozzle spray needs to be changed, one of the clamping rods is pulled downward through the clamping rod, and the clamping rod drives the slider to slide on the inner wall of the guide rail. The clamping rod pulls the metal adjustment ring at the top through the metal tension wire, and one side of the metal adjustment ring begins to tilt and bend, thereby driving the angle adjustment hose to bend.

The clamping rod pulls the metal adjustment ring at the top through the metal tension wire, and one side of the metal adjustment ring begins to tilt and bend, thereby driving the angle adjustment hose to bend. The bending angle of the angle adjustment hose is determined by the length of the metal adjustment ring pulled out, which is convenient for controlling the spray angle.

[0018] The output shaft of the electric motor drives the active gear to rotate, and the active gear drives the rotating tube to rotate through the gear ring. The rotating tube adjusts the direction of the nozzle through the docking tube, the pull-out tube and the angle adjustment hose, and further controls the direction in which the cleaning liquid is sprayed. By controlling the angle and direction of the spray, the wound and incision can be fully rinsed and cleaned during the operation, which is beneficial to improving the patient's recovery effect after surgery.
