Description

A kind of expander

Technical field

The utility model relates to a kind of transportation system components that plugging device is sent into inside of human body affected part, more particularly to one kind Expander.

Background technique

Patent ductus arteriosus, aberrant angiogenesis access, atrial septal defect, acleistocardia and ventricular septal defect are a kind of serious The deformity of patient's growth and development is influenced, previous surgical operation is its unique treatment method, and interventional therapy is removed and opened for patient Outside another therapy approach, more important is it to have many advantages compared with surgical operation, such as: the hospital stays is short, does not need tracheae inserts Caudal block, patient suffering is small, damages and does not leave any abnormal pigmentary deposit on the skin trace etc., therefore the receiving by more and more patients less,.Arterial duct Arteriosus occluder, aberrant angiogenesis access plugging device, atrial septal defect plugging device, oval hole plugging device, ventricular septal defect envelope Stifled device is exactly the interventional therapy special equipment of these illness.Its mechanism of action is to be placed in the metal truss structure containing filler Lesion, mechanical blocking abnormal blood flow, and thrombosis or stimulation surrounding tissue growth are induced by filler, reach envelope Close defect, the purpose of radical curing of disease.

Plugging device is to be sent into inside of human body affected part by transportation system.As shown in Fig. 1, Fig. 8, Figure 15, Figure 22, conveying System includes the sheath 1 for constituting plugging device Transfer pipe, for guiding sheath 1 to be inserted into the expander 2 in inside of human body affected part, being used for Plugging device is passed through sheath 1 to send to the driven rod 3 in inside of human body affected part, the loader 4 for being used to be placed in plugging device in sheath 1.

Sheath 1 includes tube body 1-1, and the pipe tail of tube body 1-1 is connected to tube socket 1-2, and tube socket 1-2 passes through connecting tube 1-4 and three Port valve 1-3 connection.

Expander 2 includes tube body 2-1, and the pipe tail of tube body 2-1 is connected to tube socket 2-2, what the tube head of tube body 2-1 was tapered in Expanding pilot head 2-3.

Driven rod 3 includes body of rod 3-1, and the bar tail of body of rod 3-1 is fixedly connected by fixing screws 3-3 with handle 3-2, bar The head of body 3-1 is provided with transfer head 3-4, is provided with screw thread on transfer head 3-4.

Loader 4 includes tube body 4-1, and the pipe tail of tube body 4-1 be connected to tube socket 4-2, tube socket 4-2 pass through connecting tube 4-4 and Triple valve 4-3 connection.

In use, first expander 2 is inserted into sheath 1, then the tube head of sheath 1 is inserted by inside of human body by expander 2 Then expander 2 is extracted in affected part；The transfer head 3-4 of driven rod 3 is passed through into loader 4, plugging device is screwed on transfer head 3-4, Driven rod 3 is stirred, enters plugging device in loader 4, then loader 4 is connected with sheath 1, then, inserting dynamic driven rod 3 makes Plugging device enters sheath 1 until inside of human body affected part from loader 4, and turning driven rod 3 makes plugging device be detached from driven rod 3, finally Extract driven rod 3 and sheath 1.

As shown in Fig. 2, in the prior art, the tube body 1-1 of sheath 1 is by skeleton pipe 1-1-1, inner protective tube 1-1-2, outer protection tube 1-1-3 is constituted.Wherein, skeleton pipe 1-1-1 is by waiting wire-diameter steels i.e.: cylindrical steel wire is wound i.e. through spiral and silk: screw pitch is equal to Gauge of wire constitutes the solenoid of isometrical uniform pitch.When tube body 1-1 made of solenoid with this structure is used for sheath 1, The side wall of tube body 1-1 can be made very thin, the outer diameter for being conducive to the cavity for increasing tube body 1-1 or reducing tube body 1-1.But by It is all the same from tube head to the amount of deflection of pipe tail in tube body 1-1, so, the tube head of tube body 1-1 is easy to advance in inside of human body curve, can That during being subsequently inserted, the strength of pipe tail is not easily controlled, strength is just bent with big pipe tail, strength used small and Insert motionless pipe tail.

As shown in figure 3, skeleton pipe 1-1-1 is substituted for by equal wire-diameter steels i.e.: cylinder in order to which the strength of pipe tail is easy to control Shape steel wire interweaves i.e. through isodensity: the constant isometrical isopycnic grid pipe of composition of steel wire radical in unit length.With this knot When tube body 1-1 made of the grid pipe of structure is used for sheath 1, the side wall of tube body 1-1 can also be made very thin, be conducive to increase tube body The cavity of 1-1 or the outer diameter for reducing tube body 1-1.But since tube body 1-1 is all the same from tube head to the amount of deflection of pipe tail, so, The tube head of tube body 1-1 is not easy to advance in inside of human body curve, but, during being subsequently inserted, the strength of pipe tail is easy Control, strength are not also bent with big pipe tail.
