Problems solved by technology

Intrahepatic bile duct stones are one of the common diseases in the hepatobiliary department. The most effective way to treat intrahepatic bile duct stones is to remove the stones through surgery. The most commonly used stone removal tool in surgery is the stone removal device. During the stone removal process, use the stone removal device Clamp the stone and then take it out, but the structure of the stone removal device in the traditional technology is single, the length of the entire stone removal device cannot be adjusted according to the needs of use, and the use requirements of different operating environments cannot be met, and the flexibility is poor

Embodiment 1

[0027] Such as figure 1 As shown, in the embodiment provided by the present invention, a device for removing hepatic and bile duct stones includes a sleeve 1, and a spacer 2 is fixed inside the sleeve 1, and the sleeve located above the spacer 2 1. A lifting slider 6 is radially slid in the inner cavity, and a movable jaw 3 is hingedly connected to the lifting slider 6 through a hinge seat 9. The top end of the sleeve 1 is also provided with a movable jaw 3 Corresponding to the fixed jaw 4, the movable jaw 3 is made of iron material, and the top of the sleeve 1 is also provided with a magnetic attraction 5 on the same side as the movable jaw 3. When no external force is applied, Under the action of the magnetic attraction 5, the movable jaw 3 and the fixed jaw 4 can be kept in an open state, so as to facilitate the clamping of stones.

Abstract

The embodiment of the invention relates to the field of medical apparatuses, and particularly discloses a hepatic calculus eliminating device. The hepatic calculus eliminating device comprises a sleeve, wherein a separation ring is fixedly arranged in the sleeve; a lifting sliding block is arranged in an inner cavity of the sleeve above the separation ring in the radial direction in a sliding manner; a movable clamping claw is in hinging connection to the lifting sliding block through a hinging seat; a fixed clamping claw which correspondingly cooperates with the movable clamping claw is alsoarranged at the top end of the sleeve; the lifting sliding block is in supporting connection with the separation ring through a supporting spring; and a pull rope is also fixedly connected to the lifting sliding block. According to the hepatic calculus eliminating device disclosed by the embodiment of the invention, the pull rope is pulled, so that the movable clamping claw is continuously close to the fixed clamping claw, and the effect of clamping calculus is realized; and when the whole length of the hepatic calculus eliminating device is adjusted, the pull rope reeled on a reeling block isunreeled, and the length of the pull rope is fitted into the whole length of the hepatic calculus eliminating device, so that the applicability of the hepatic calculus eliminating device is effectively guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the field of medical devices, in particular to a device for removing hepatic and bile duct stones. Background technique [0002] Bile duct stones are a kind of clinical cholelithiasis, which can be divided into extrahepatic bile duct stones and intrahepatic bile duct stones according to the location of the stones. Stones located at the lower end of the common bile duct are called extrahepatic bile duct stones; and stones distributed in the bile ducts in the liver lobe are called intrahepatic bile duct stones. Intrahepatic bile duct stones are one of the common diseases in the hepatobiliary department. The most effective way to treat intrahepatic bile duct stones is to remove the stones through surgery. The most commonly used stone removal tool in surgery is the stone removal device. During the stone removal process, use the stone removal device Clamp the stone and then take it out, but the stone remov...
