Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, a gallbladder stone removal device includes a handle 1, a sheath tube 3 connected to the handle 1 at the proximal end, a push-pull rope 4 sleeved in the sheath tube 3, and a stone removal mesh bag 5 arranged at the distal end of the sheath tube 3, The two ends of the push-pull rope 4 are respectively connected to the handle 1 and the stone-taking net bag 5, and the stone-taking net bag 5 stretches out or contracts at the distal end of the sheath tube 3 under the traction of the push-pull rope 4. In this example, if image 3 As shown, the stone removal mesh bag 5 includes a bag body 6, a pulling mesh 7 and an end cap 8, the bag body 6 is semi-closed, and its opening faces the axis of the sheath tube 3, and the pulling mesh 7 is located at the bag body 6 and is open. On the surface, the far-end of pocket body 6...

Abstract

The invention discloses a gallstone removal device. The gallstone removal device comprises a handle, a sheathing canal, a push-pull rope and a gallstone removal net bag, wherein the near-end part of the sheathing canal is connected with the handle; the push-pull rope is sleeved with the sheathing canal; the gallstone removal net bag is arranged on the far-end part of the sheathing canal. The two ends of the push-pull rope are connected with the handle and the gallstone removal net bag respectively, and the gallstone removal net bag is pulled by the push-pull rope to stretch out of or retract in the far-end part of the sheathing canal; the gallstone removal net bag comprises a bag body, a traction netting wire and an end cap, the bag body is semi-closed, an opening of the bag body faces theaxis of the sheathing canal, the traction netting wire is located on the opening surface of the bag body, the far end of the bag body and the far end of the traction netting wire are fixed together and then fixed to the end cap, and the near end of the bag body is fixed to the far end of the push-pull rope. By means of the gallstone removal device, sediment-form or small-sized stones in the gallbladder can be directly taken out of the body, and the gallstone removal device is simple and practical.

Description

technical field [0001] The invention relates to a gallbladder stone removal device, which belongs to the stone removal device in the field of medical equipment. Background technique [0002] The use of a stone extraction basket to extract stones is one of the most commonly used stone extraction methods at present. But present stone-taking net basket is generally made of many metal wires, and stone-taking net basket is formed between many metal wires. When taking stones, put the net basket into the body, place the stones in the net basket by moving the net basket, and then pull the push-pull rope outward through the handle to make the metal wire shrink continuously, crush the stones and discharge them out of the body. However, this method is aimed at lumpy or large stones. For the sediment-like stones in the gallbladder, the stone extraction basket cannot capture them, let alone crush them and discharge them. Contents of the invention [0003] Aiming at the defects of the...
