Description

Technical Field

[0001] The utility model relates to the technical field of drainage tube fixation in hepatobiliary surgery, in particular to a drainage tube fixation structure after hepatobiliary surgery. Background Art

[0002] The department of biliary surgery mainly studies major diseases that seriously threaten the health of Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. After hepatobiliary surgery, it is usually necessary to use a drainage tube to guide the pus, blood and fluid accumulated between human tissues or in the body cavity to the outside of the body to prevent postoperative infection and promote wound healing. In order to prevent the drainage tube from being pulled, it is necessary to use a fixing device to fix it.

[0003] After searching, the prior art, patent application number CN202121742398.8, discloses a postoperative drainage tube fixing device for hepatobiliary surgery, comprising: a fixing plate, a first strap is connected to the right side of the fixing plate, and a Velcro is provided above the first strap; an elastic connecting belt is arranged on the left side of the fixing plate, and a second strap is connected to the left side of the elastic connecting belt; a fixing pile is fixedly installed in the middle above the fixing plate, a card slot is opened on one side above the fixing pile, and a movable plate is installed on one side above the card slot, and a card hole is opened in the middle below the movable plate, and a non-slip pad is provided in the card hole; an adjusting knob is installed in the middle above the movable plate. Compared with the existing device, the postoperative drainage tube fixing device for hepatobiliary surgery can wrap the drainage tube through the fixing pile, the adjusting knob can adjust the position of the movable plate, and the card hole of the semi-cylindrical structure can fit with the outer wall of the drainage tube, so that the drainage tube can be fixed to the fixing plate.

[0004] The above technical solution also has the following defects: after the postoperative drainage tube fixing device for hepatobiliary surgery is fixed to the patient's waist, the elastic connecting belt will be tightly attached to the patient's waist. At this time, the air permeability of the skin covered by the elastic connecting belt is significantly weakened, and it will also cause marks on the skin attached to the airbag, which not only reduces the patient's comfort but also increases the pressure on the patient's waist. A clamping hole is opened in the middle part below the movable plate, and the drainage tube is fixed through the clamping hole. If the clamping force is not enough, the position of the drainage tube is prone to dislocation. If the clamping force is large, the drainage tube is deformed and the drainage performance of the drainage tube is reduced. Utility Model Content
