Embodiment Construction

[0022] see Figure 1 to Figure 6 , The invention relates to a three-wire variable-range stone-taking basket device, including a control end and a working end.

[0023] The control end includes a handle main body 2, the handle main body 2 is a hollow tube, and a fixed rod 3 is arranged inside it, and the rear end of the fixed rod 3 is connected with the fastening rear cover 4 through a latch 5, and the fixed rod 3 is connected with the fastening rear cover 4. A sliding rod 1 is arranged between the handle main bodies 2, and the front end of the sliding rod 1 stretches out from the handle main body 2, and can slide back and forth relative to the handle main body 2 and the fixed rod 3, so that the sliding rod 1, the handle main body 2, the fixed rod 3, A push-pull handle that can be freely pushed and pulled is formed to form a control end.

[0024] Three ranges of 8mm, 11mm, and 15mm can be set in the handle body 2. By twisting and tightening the back cover 4 to act on the latch...

Abstract

The invention relates to a three-wire variable-range calculus retrieval mesh basket device. The three-wire variable-range calculus retrieval mesh basket device comprises a control handle and a sheathtube arranged on the control handle, wherein a mesh basket is connected to the sheath tube; the mesh basket is unfolded or contracted through operation of the control handle; when the mesh basket is unfolded, the mesh basket is in a triangular cone shape, and the bottom face of the mesh basket is in an opening shape; and when the mesh basket is contracted, the calculus retrieval mesh basket is integrally contracted into the sheath tube. Compared with a four-wire mesh basket, the three-wire variable-range calculus retrieval mesh basket device has the advantages that calculi in a body can be more conveniently and accurately grasped without injuring blood vessels. On the basis of the three-wire structure, the applicant, namely, a company, abandons a mesh basket with a fixed specification andadopts a variable-range design, the calculus retrieval mesh basket does not need to be frequently replaced for calculi with different sizes and different structures in the operation process, the maximum unfolding degree of the mesh basket is directly adjusted and changed through the handle, and the calculi can be removed at a time, so that the operation efficiency is improved, and the pain of a patient is greatly relieved.

Description

technical field [0001] The invention relates to a three-wire variable-range stone extraction net basket device and a use method thereof, belonging to the technical field of medical devices. Background technique [0002] Kidney stones are common diseases of the urinary system. Abnormal metabolism of the body, urinary tract obstruction, infection, foreign bodies and the use of drugs are common causes of stone formation. With the development of science and technology, flexible ureteroscopy lithotripsy has become a treatment for kidney stones. Or one of the methods for upper ureteral stones. Under the flexible ureteroscope, the holmium laser is used to crush the stones, and then remove them as much as possible. The stone extraction basket is a device for removing stone fragments after crushing the stones under the flexible ureteroscope. The existing four-wire lithotripsy basket has a relatively simple structure and specifications. During the operation, since the size of the sto...
