Description

High-efficiency stone-taking net basket

Technical Field

The utility model mainly relates to the field of medical equipment, especially, relate to high-efficient stone basket.

Background

The calculus removing basket is used for capturing and removing ureteral calculus under an endoscope.

Conventional stones are too large and require a plan to be easily removed. The existing stone-taking net basket is composed of three to four metal wires, when stones are taken, the metal wires rub the side wall of human tissue to form friction damage, the crushed stones taken out at a time are few, the efficiency is low, fine stone chips are difficult to take out completely, and the risk of relapse is caused.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect of prior art, the utility model provides a high-efficient stone basket of getting, set up at the 1 inside action bars of beam tube including beam tube 1 and activity, action bars one end is equipped with and gets stone basket 2, gets 2 head ends of stone basket and sets up and get stone filter screen 3, gets stone filter screen 3 and is hollow cylindric, and collapsible holding is in beam tube 1, and lateral wall mesh maximum aperture is less than 2 mm.

Preferably, the stone extraction basket 2 comprises at least three constrictions fixed to the open edge of the stone extraction screen 3.

Preferably, the tail end of the stone taking filter screen 3 is provided with a limiting block 4.

Preferably, the diameter of the cylinder hole of the stone taking filter screen 3 after release is less than 5 mm.

Preferably, the bottom of the inner cavity of the stone taking filter screen 3 is connected with a stone taking line 6.

Preferably, one end of the stone taking line 6 is fixedly connected to the stone taking basket 2.

Preferably, the stone-taking line 6 is an elastic line, and a stone-taking baffle is arranged close to the joint of the stone-taking line and the inner cavity of the stone-taking filter screen 3.

Preferably, the top end of the bundle tube 1 is flared.

The utility model has the advantages that:

1. the quantity can be increased by taking stones once, and the efficiency is improved;

2. the stone is taken out cleanly, and fine stone chips can also be taken out

3. The times of fetching stones are reduced, and the friction damage is reduced.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention and are not intended to limit the scope of the invention.

As shown in fig. 1-2, the present invention comprises: beam tube 1 sets up at the inside action bars of beam tube 1 with the activity, and action bars one end is equipped with gets stone basket 2, gets 2 head ends of stone basket and sets up and gets stone filter screen 3, gets stone filter screen 3 and is hollow cylindric, and collapsible holding is in beam tube 1, and lateral wall mesh maximum aperture is less than 2 mm.

When in use, the tube bundle 1 firstly enters the human body, and the calculus removing basket 2 enters from the interior of the tube bundle 1 and then comes out from the body of the patient. Can collect knot stone through pull-back calculus extraction basket 2, because calculus extraction basket 2 does not have the constraint thing, appear the cage form after scattering, get stone filter screen 3 in the cracked calculus entering of pull-back in-process and be collected, liquid flows out from the gap in the basket, and the rubble can not be overflow. Because the single stone extraction is more, the side wall of the stone extraction filter screen 3 can be caused to bulge outwards and clamped at the pipe opening of the beam tube 1, the probing degree of the beam tube 1 and the probing degree of the stone extraction basket 2 cannot be too much at each time, and strict control is required. When the single stone removal is excessive, the stone removal net basket 2 needs to be stretched again to release redundant broken stones.

Meanwhile, due to the existence of the stone taking filter screen 3, the stone taking basket 2 only leaves few stone chips when working, and the stone chips are discharged out of the body through the self-circulation of the human body and are not easy to relapse.

Preferably, get stone basket 2 and include at least three stem of restrainting, three stem of restrainting is fixed with the opening edge of getting stone filter screen 3 of restrainting, and the selection of its fixed point generally is fixed in proper order for the equidistance, and the guide of the stone basket 2 of being convenient for gets stone filter screen 3 and opens the back, collects and takes out tiny stone bits.

Preferably, get 3 ends of stone filter screen and be equipped with stopper 4, because get stone filter screen 3 and need pass in and out beam tube 1 repeatedly, the stopper 4 of head mount can prevent and get 3 tops of stone filter screen card die.

Preferably, the bore diameter of the cylinder of the stone taking filter screen 3 after being released is less than 5mm, so that the phenomenon that the inside of the beam tube 1 is blocked due to excessive stone taking in one time is prevented.

Preferably, the calculus removing line 6 is an elastic line, and a calculus removing blocking body is arranged close to the joint of the calculus removing line and the inner cavity of the calculus removing filter screen 3.

After the stone taking filter screen 3 takes out the broken stones, because the inner diameter of the stone taking filter screen 3 is small, all the broken stones are difficult to take out, at the moment, the stone taking line 6 is pulled, the stone taking baffle body is dragged, and residues are taken out.

Preferably, the top end of the beam tube 1 is provided with a bell mouth, so that the stone taking filter screen 3 is conveniently bundled into the beam tube 1 after the stone is taken.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Those skilled in the art can modify and/or change the above-described embodiments without departing from the spirit and scope of the present application. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims be embraced by the present application.
