Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with drawings and the specific embodiments,
The utility model is described in further detail.
As shown in Figs. 1-2, the utility model provides a kind of telescopic disposable stone extraction basket of novel belt funnel, packet
Control handle 1, the sheath being connected with control handle 1, mesh basket 3 are included, the sheath includes being sequentially sleeved in from inside to outside together
4th pipeline 4, third pipeline 5, the second pipeline 6, the first pipeline 7, wherein the 4th pipeline main structure is stainless steel wire, third
Pipeline 5, the second pipeline 6, the first pipeline 7 are hollow tubing conductor, and 4 front end of the 4th pipeline is connect with 3 head of mesh basket, before third pipeline 5
End is connect with the tail portion of mesh basket 3, and the mesh basket 3 is telescopic reticular structure, and the mesh basket is worked out by several mesh basket seal wires
It forms, the 4th pipeline pulls to the right mesh basket, can strut mesh basket, the tail portion of the front end connection funnel 8 of the second pipeline 6, the funnel 8
It can shrink or stretch.
The funnel includes external hopper walls and internal spring 2, and the hopper walls are by the medical height with retractility
Molecular material is made into, and the main structure of the spring is netted.Spring can be the reticular structure of similar mesh basket, in the work of external force
It may be implemented to support under open and close, high molecular material and contained spring are integrated through injection molding, and external high molecular material has
Retractility can be realized in the state that internal support spring is open and close and freely expand and reduce.Not according to operative site
Together, the diameter of funnel head opening can be different, the product of different tissue (such as urethra) selection correspondingly-sizeds, funnel openings
Size is smaller than tissue, facilitates disengaging tissue.Foreign matter or calculus 9 are encountered, funnel is realized by the active force of spring with reaction force
Opening and tube wall.The process that funnel is opened is as follows: funnel travels forward, and resists calculus 9, and funnel inner spring is by resistance to back brace
Open-drain bucket.Funnel closing process: the second channel interior be it is hollow, the inside is provided with connecting line, and connecting line tail portion is connected to hand
At handle, front end is connect with funnel, and connecting line funnel is pulled to shrink.
The third pipeline 5, the second pipeline 6, the first pipeline 7 material be high molecular material.In four pipelines, the second pipeline
Can be movable in the first pipeline, it can prevent funnel from accidentally opening, funnel is placed in the second pipeline, the second pipeline is not leaked out,
The second pipeline is allowed in this way across the first pipeline, then opens funnel, can prevent funnel from accidentally opening.
The mesh basket 3 is medical stainless steel material.According to the needs of processing different size calculus, the mesh of net can be set
Count into different densities, Fig. 3 provide low-density, middle density, 3 kinds of different densities of high density mesh basket structure chart.Mesh basket can be with
It is designed to pull rod type, i.e. the tail portion of mesh basket is the big pull rod in gap, and front end is mesh basket, as shown in Figure 4.
The utility model improves in traditional mesh basket structure, now will increase by the 4th pipeline among mesh basket, mesh basket is set
It is calculated as netted scalable form (or railing form), rear portion increases the band contractile funnel of spring, by the first pipe when product uses
Road is put into operative channel to solid position, after the second pipeline reaches solid position by the first pipeline, operates instrument, in funnel
Spring struts, to strut funnel, third pipeline (front end is with the 4th pipeline of connection) reaches solid position by the second pipeline
Front end pulls the 4th pipeline of connection, struts net, as the pulling of funnel direction, pulls in solid in funnel, passes through pipeline for solid
It pulls out, completes operation.
In conclusion the utility model not only has the advantages that simple in sturcture, ingenious in design, but also the design is original
It being made improvements on stone extraction basket, structure is simple, and it is easy to accomplish, the first pipeline is put into operative channel to solid position, the second pipe
After road reaches solid position by the first pipeline, instrument is operated, funnel inner spring struts, to strut funnel, third pipeline is logical
It crosses the second pipeline and reaches solid position front end, pull the 4th pipeline of connection, strut net, pulled to funnel direction, by solid drawing
Enter in funnel, prevent calculus or stone debris from falling off, pulled out solid by pipeline, complete operation, saves operating time, have
Effect improves the success rate for taking stone, greatly improves and takes Shi Xiaoguo, mitigates surgical intensity, accelerates patient's recovery process.
