Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of foreign matter removal device as shown in Figure 1, Figure 2, Figure 3 shows, comprises handle 1, finger ring 2, runner 3, outer sheath 4, snare 5, mesh bag 6, wiring 7, connection tube 8 and seal wire 9; Finger ring 2 is slidably located on handle 1, handle 1 is connected with the near-end of outer sheath 4, seal wire 9 is worn in outer sheath 4, the near-end of seal wire 9 is connected with finger ring 2, seal wire 9 is arranged with runner 3 and runner 3 can drive seal wire 9 to rotate, runner 3 is arranged on handle 1, the far-end of seal wire 9 is fixedly connected with by the rear end of connection tube 8 with snare 5, described snare 5 can be taken in the far-end of outer sheath 4, snare 5 is provided with mesh bag 6, mesh bag 6 is fixedly connected with snare 5 near the front portion of snare 5 front end, and mesh bag 6 is connected with connection tube 8 by wiring 7 near the rear portion of snare 5 rear end.
Foreign matter removal device is primarily of extracting portion part and operation control assembly composition.Extracting portion part mainly comprises the parts such as mesh bag, wiring, snare; Operation control assembly is primarily of part compositions such as finger ring, handle, runner, seal wire, outer sheath.Extracting portion part gathers foreign body in the course of the work and collects, operation control assembly in order to control extracting portion and divide rotation, open or reclaim.Above-mentioned two parts collaborative works, complete the operation of taking foreign body.Above-mentioned two parts are connected by connection tube.
In the present embodiment, as shown in Figure 3, described mesh bag 6 front portion is fixedly connected with snare 5 by several fixed-nodes 62, described fixed-node 62 is fixed on snare 5 by the grid on mesh bag 6 is formed by mode that is bonding or binding, Fig. 4 is for be adhesively fixed by glue, and Fig. 5 is for fix by wiring colligation.
As shown in Figure 2, described wiring 7 is tied a knot with at least one mesh node 63 at mesh bag 6 rear portion and is connected, and described wiring 7 is tied a knot fixing after the elongated portion of mesh bag 6 is wound around some circles by the rear and front end of connection tube 8 respectively, and knotting point is 71,72.Use wiring at mesh bag near snare rear portion, walk around one or several grid places knotting; In addition, mesh bag elongated portion, at connection tube two ends, is wound around circle or some circles by wiring respectively, as far as possible near the knotting of connection tube end.Such mode, structure simply easily realizes, and well can ensure fixed effect.Above-mentioned node can be fast knot and can be slip-knot, preferred fast knot.
Be connected with snare 5 by multiple slip node 61 in the middle part of described mesh bag 6, described slip node 61 is socketed on snare 5 by the grid activity on mesh bag 6 and is formed.Such net suspension mode, makes to ensure in mesh bag work process that each several part and snare are better fitted, mesh bag each several part uniform force, is not easy to damage; And foreign body can not spill from A space.
The front and rear of mesh bag is fixed respectively, and mid portion is not fixed, and can be free to slide.Such mode can ensure that mesh bag stretches out with reclaimer operation smooth with snare, is not shifted and comes off; And catching in removal process, middle slip part can move forward and form darker pouch, helps to catch larger target as far as possible.
