Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 The shown bile duct stone removal device includes an outer tube 1 with an operating handle at the rear end, an air pump tube 3 sleeved inside the outer tube 1 , and a balloon tube 4 sleeved inside the air pump tube 3 . A liquid injection port 2 communicating with the inner cavity of the outer tube 1 is provided on the side wall of the outer tube 1 near the end of the operating handle. The rear end of the air bag tube 4 is connected with an inflation device, and the front end is connected with a radially expandable air bag 5 , and the air bag tube 4 is a rigid tube. The rear end of the air pump pipe 3 is connected with an air pump, and the front end is connected with a suction cup 8 . There is a suction hole communicating with the air pump pipe 4 at the bottom of the suction cup 8 . The outside of the suction cup 8 is connected with an expansion br...

Abstract

The invention relates to a bile duct stone extractor, which comprises an outer tube (1), an air pump tube (3) and a balloon tube (4). The air pump tube (3) is sleeved inside the outer tube (1), and the balloon tube (4) is sleeved inside the air pump tube (3). A fill inlet (2) is communicated to the back end of the outer tube (1). An inflating unit is connected to the back of the balloon tube (4),and a balloon (5) is connected to the front end of the balloon tube (4). An extracting pump is connected to the back end of the air pump tube (3), and a sucker (8) is connected to the front end of the air pump tube (3). A dilating support (9) is connected to the outside of the sucker (8). By the aid of the bile duct stone extractor, stone extraction efficiency in gallstone operation is high, and stone caked on the wall of a bile duct can be extracted easily. The bile duct stone extractor cause low harm to patients, while contrast agent, relaxant, therapy drug and the like can be injected in any time according to needs of operations.

Description

technical field [0001] The invention relates to a medical device, in particular to a bile duct stone removal device. Background technique [0002] Gallstone is a common disease, and its incidence is directly proportional to the patient's age. With the increasing proportion of my country's aging population, the number of gallstone patients is also increasing. For patients with symptomatic gallstones, if they do not seek medical attention in time, serious complications may occur, even life-threatening. At present, drug treatment is mostly ineffective, and surgical treatment is generally required, such as laparotomy and endoscopic lithotomy. Among them, endoscopic lithotomy has gradually shown its advantages due to its small trauma, quick recovery, and is suitable for intrahepatic stone extraction. [0003] The currently commonly used stone removal device in clinic is as shown in the patent No. 200820057990.2. Since the stone removal basket of this kind of stone removal devi...
