[0002] In the process of medical general surgery, hepatobiliary drainage is a common medical operation, which involves cutting the common bile duct at a high position, gradually dilating the hepatobiliary stenosis under direct vision, and performing drainage. For example, the patent with publication number CN111956872A discloses a hepatobiliary drainage device, which specifically relates to the technical field of medical devices. A hepatobiliary drainage device includes a drainage tube, a liquid storage tank is provided on the drainage tube, and a vacuum pump is connected to the liquid storage tank. The device is characterized in that: a baffle with a through hole at the bottom is provided in the drainage tube, a sleeve is slidably connected to one side of the baffle, a blocking block is rotatably connected in the sleeve, and a plurality of drainage grooves with gradually increasing diameters are provided on the circumference of the blocking block, which solves the problem that the existing hepatobiliary drainage device cannot adjust the drainage efficiency according to the actual situation of the patient, and can be used for drainage of liquid in the patient's body cavity; Another example is a patented hepatobiliary drainage device with publication number CN108939179A, which includes a conical head, a rubber elastic bag, a liquid inlet, a nut, a tube body, a support rod, a drainage tube, a cubic metal block, a trigger, a spring, a strip support block, a connecting tube, a first valve, a second valve, a third valve, a fourth valve, an air inlet pipe, a rubber hand-held pressure ball, a liquid storage tank, a scale bar, a vent, a liquid discharge tube, an absorbent gelatin sponge, a ring-shaped fixed bracket, a bracket joint, a first connecting tube and a second connecting tube. When in use, the effusion and debris in the affected area can be more thoroughly removed. The absorbent gelatin sponge can absorb the effusion and adsorb the debris on the surface of the absorbent gelatin sponge. The rubber hand-held pressure ball can make the drainage work more convenient and quick, which not only makes the drainage effect more obvious and more efficient, but also greatly simplifies the workflow of medical care. For example, a hepatobiliary drainage device with publication number CN115869476A comprises a drainage catheter, a dredging mechanism and a negative pressure mechanism; one end of the drainage catheter is connected to a puncture needle, and the other end is connected to the negative pressure mechanism, and a connecting port is provided on the drainage catheter; the dredging mechanism comprises a housing, a driver and a dredging rod, and a dredging port is provided on the housing, which is detachably connected to the connecting port, and the drainage tube is dredged by expanding the tube wall and spiral drilling, which has a good dredging effect, and does not need to be drawn out of the patient's body, nor does it need to be injected with water into the patient's body, and is more convenient to use; Most of the above-mentioned existing technologies have improved their overall structure, but the existing hepatobiliary drainage device for general surgery cannot perform adaptive positioning processing at the wound during operation, so as to ensure the stability of its drainage position and the sealing treatment of the wound, resulting in the wound position being easily exposed to the air for a long time and causing infection, and thus there are certain limitations in use.
