Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the most preferred embodiment of the present invention is a stone basket with variable basket wire number, comprising a basket component 1, a push-pull wire, an outer tube 3, a three-way tube 4, a guide head 5, a core bar 6, a sliding ring 7 and a pull cable 9, wherein the guide head 5 is fixedly arranged at the front end of the basket component 1, the end of the basket component 1 is connected with the front end of the push-pull wire, the end of the push-pull wire is fixedly connected with the sliding ring 7, the sliding ring 7 is slidably sleeved on the core bar 6, the outer tube 3, the core bar 6 and the three-way tube 4 are all sleeved on the push-pull wire, the rear end of the outer tube 3 is fixedly connected with the front end of the three-way tube 4, the rear end of the three-way tube 4 is fixedly connected with the core bar 6, the side of the three-way tube 4 is further provided with a third tube orifice 41, the first tube orifice of the three-way tube 4 is forward, the second tube orifice of the three-way tube 4 is backward, the central axis of the third tube orifice 41 and the included angle α of the horizontal line are 30-70 degrees, the number of the basket component 11 is equal to or more than the number of the basket handle of the basket 11, the basket component, the number of the basket component is equal to the number of the basket component, the handle of the pull cable is equal to the handle.

In this embodiment, the total number of the basket wires on the basket assembly 1 is 4, the coils 8 are sleeved on the two adjacent basket wires 11, and the included angle α between the central axis of the third pipe orifice 41 and the horizontal line is 45 °.

A protective sleeve 10 is further arranged between the outer pipe 3 and the three-way pipe 4, and the protective sleeve 10 is sleeved on the push-pull wire and the pull cable 9.

The working process is as follows: as shown in figures 1-3, in the operation process of extracting a large calculus, the coil 8 is pulled backwards to the front end of the outer tube 3 by the operating handle 2 shown in figure 1, the total number of basket wires 11 on the basket assembly 1 is 4, the position of the operating handle 2 is locked by the operating handle locking mechanism, and a small calculus can be extracted by pushing and pulling the sliding ring 7. When the basket wires 11 on the basket assembly 1 are opened, the operating handle 2 pushes the inhaul cable 9 to advance, so that the coil 8 advances, two adjacent basket wires 11 are close to each other and are basically combined into one, the distance between the basket wires 11 is increased, large stones 12 (shown in figures 2 and 5) can be conveniently taken out, finally, the operating handle 2 is pulled again, the baskets are restored into 4, the stones are prevented from slipping (shown in figure 3), and the sliding ring 7 is pulled, the stones are tightened and taken out. The basket wires 11 can be switched between 4 and 3 by pushing and pulling the operating handle 2. In clinical use, when a large stone 12 is encountered, the stone cannot enter the basket through the gaps (as shown in fig. 1 and 4) because the gaps between the 4 basket wires 11 are small.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
