An auxiliary device for removing gallstones from the cystic duct
The application provides an auxiliary device for removing gallbladder stones from a cystic duct, which comprises a longitudinal extension body with a proximal end and a distal end, and a dilating body connected to the distal end of the longitudinal extension body, the cross section of the dilating body increases along a first longitudinal direction, and the dilating body is provided with an open slot, wherein the first longitudinal direction is opposite to the direction of the auxiliary device entering a target subject. Based on the auxiliary device for removing gallbladder stones from a cystic duct, the application uses a cystic duct incision method to replace a bile duct incision method, specifically, after gallbladder removal, the auxiliary device is placed along the cystic duct, and a knife placed in the open slot is used to incise the cystic duct, so that the dilating body of the auxiliary device is used to dilate the cystic duct with a small diameter, and the operation purpose is achieved. Since the bile duct is not damaged, the patient does not need to be placed with a T-shaped drainage tube after the operation, and the postoperative pain of the patient is greatly reduced.
