Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Fig. 1,5,8, Endoscopic Treatment magnetic bead disclosed by the utility model, including at least one 1 and fixing line
2, at least one of which magnet pearl 1 is equipped with fixing line 2, and the both ends of fixing line 2 and magnet pearl 1 are affixed.
Magnet pearl 1 at least there are two, can according to practical operation need select use magnet pearl 1 number, such as Fig. 4,7,10
Shown, there are three magnet pearls 1, and multiple magnet pearls 1 attract can form magnetic bead string together, increases drawing gravity, opens to increase
Power, preferably exposure removing position.
Embodiment 1
As shown in Figure 1, 2, the magnetic pole of magnet pearl 1 descends both ends, the both ends of fixing line 2 and magnet pearl on it in the present embodiment
1 upper end is affixed.The end face of the upper and lower ends of magnet pearl 1 is the plane being parallel to each other.The cross section of magnet pearl 1 is circle.Magnetic
The diameter of 1 cross section of iron shot is greater than the height of magnet pearl 1.Preferably, magnet pearl 1 is cydariform.Magnet pearl 1 is solid construction.
As shown in figure 3, two sides opposite on magnet pearl 1 are respectively equipped with a fixing line connector 11, the two of fixing line 2
End is embedded in respectively in one of fixing line connector 11, and fixing line 2 is made to be closely coupled to the side of magnet pearl 1.
The distance between two fixing line connectors 11 are 0.5cm-1cm.The length of fixing line 2 is 2cm-4.2m.For example,
The length of fixing line 2 is 2.5cm, 3cm or 4cm, and certainly, the length of fixing line can according to need reasonable setting, and unlimited
In above-mentioned length.Wherein, the diameter of magnet pearl 1 is 0.8cm-1cm.
Magnet pearl 1 at least there are two, can according to practical operation need select use magnet pearl 1 number, as shown in figure 4,
There are three magnet pearls 1, and magnet pearl 1 attracts forms magnetic bead string together.Have that magnet pearl 1 of fixing line 2 only with a magnet
Pearl 1 is attracting and fixing line 2 is located at upper end.
Embodiment 2
The present embodiment the difference from embodiment 1 is that: as shown in Fig. 5,6,7, magnet pearl 1 be ferromagnetic sphere, magnet pearl 1
Opposite two sides are respectively equipped with a fixing line connector 11, preferably, fixing line connector 11 is set to the middle part of magnet pearl 1
Position, the both ends of fixing line 2 are embedded in respectively in one of fixing line connector 11.
Embodiment 3
The present embodiment the difference from example 2 is that: as shown in Figure 8,9, 10, the left and right sides of magnet pearl 1 is plane,
Fixing line connector 11 is set to the center of plane.
Embodiment 4
The present embodiment the difference from embodiment 1 is that: as shown in figure 11, at least one of which magnet pearl 1 be equipped with two
