Embodiment 1

[0028] Refer Figure 1-12 A gallbladder stones, including outer casing 1, and the outer casing 1 is provided with a movable block 2. The lower surface of the movable block 2 is fixedly mounted, and the outer casing 1 at the top of the movable block 2 is fixedly mounted, and there is a movable block 2. The corresponding pulling mechanism is moved by pulling the movable block 2 in the outer sleeve 1 with pulling activity block 2. The pull mechanism includes a wire 9, a fixed sleeve 10, a pull plate 11, a spring 12, a pull ring 13, and a wire 9 fixed to the upper surface of the movable block 2, and the outer sleeve 1 at the top of the movable block 2 is fixed to the fixed sleeve 10, The other end of the wire 9 is fixed upward, and the fixing sleeve 10 is fixed to the pull plate 11, and the fixing sleeve 10 is fixed between the sleeve 12, and the pull plate 11 is moved away from the fixed sleeve 10 on the surface. Pull ring 13.

[0029] The stone module includes the connecting plate 3,...

Embodiment 2

[0033] Refer Figure 1-12 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the drive mechanism includes a crank 16, a drawn cord 17, a pulled mechanism, and the rotating shaft 4 is also fixed to fix the crank 16, pull the rope 17 One end is fixed to the crank 16 at one end of the rotary shaft 4, and the other end of the drawing cord 17 is traveling up through the movable block 2 along the outer casing 1, outside the outer sleeve 1, the outer sleeve 1, the outer sleeve 17 end and pull The brake mechanism is fixed, and the pull mechanism is used to pull the drawstring 17 so that the drawing cord 17 drives the crank 16 to drive the rotating shaft 4. The drawing mechanism includes a gas cylinder 19, a piston rod 18, a piston 20, a blowout 21, and a sealing plate is fixedly mounted, and the sealing plate is formed through the piston rod 18 in which the piston 19 is coaxial, the piston rod in the piston 19 in the gas cylinder 19 The pisto...

Abstract

The invention relates to the technical field of medical instruments, in particular to a gallstone extractor. The gallstone extractor comprises an outer sleeve, a movable block is arranged in the outer sleeve, a calculus removing module is fixedly mounted on the lower surface of the movable block, a pulling mechanism corresponding to the movable block is fixedly mounted at the tail end of the outer sleeve above the movable block, and the pulling mechanism is used for pulling the movable block to move in the outer sleeve; and the calculus removing module comprises a connecting plate, a rotating shaft, an iron movable rod, a calculus removing mechanism, a driving mechanism and a magnetic attraction mechanism. By arranging the calculus removing mechanism with a swingable net bag, calculus can be taken out more conveniently and quickly.

Description

Technical field [0001] The present invention relates to the field of medical devices, in particular, to a gallbladder stones. Background technique [0002] Gallbladder stones are a clinically common disease, one of cholelosemia, mostly cholesterol stones or mixed stones and melanoid stones mainly based on cholesterol. According to the calculus component, there is a cholesterol spectrum: it is the premise of bile cholesterol and is formed under the action of promoting nuclear factors, and the gallbladder shrubilin receptor is lacking, bacterial and immunoglobulin also affect the formation of cholesterol stones. The gene also plays an important role in the formation of stone formation, and cholorin stones: essence is a high polymer formed by bilirubin and a plurality of metal ions such as Ca2 +, Mg2 +. Decreased bile acid, bacterial infection, glycoprotein, and free radicals can promote the formation of stones. During the treatment of gallbladder stones, the common method is to rem...
