Abstract
This utility model relates to a kind of head end adjustable-angle seal wire, comprises guidewire body, regulates silk and regulating handle.The front end of described guidewire body is fixed with adjustment silk, and described adjustment silk to be inlaid in guidewire body and to stretch out from the rear end of guidewire body.Then stretch and regulate silk that the front end of guidewire body can be made to bend, thus regulate the angle of guidewire body front end, and then the angle of stopper and heart atrial septal defect position are coincide, ensure therapeutic effect.By regulating silk stretching structure to regulate adjustment silk, can the operation of person greatly easy to use, improve Position location accuracy.Regulate the design of silk stretching structure can regulate more accurately the angle of guidewire body front end, result of use is very good.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, particularly a kind of seal wire of head end angle adjustable.
Background technology
One of common method for the treatment of of heart atrial septal defect adopts heart atrial septal defect plugging device to carry out interventional therapy.During treatment, first seal wire positioning plugging device transfer position will be utilized, then enter stopper delivery sheath along seal wire, extracted out by guidewire body, heart occluder is transported to the assigned address of heart by recycling push rod along delivery sheath, open stopper and blocked by heart defect.But due to the position of heart atrial septal defect, residing plane difference, and existing seal wire angle is fixed, and can not regulate.Thus, although stopper can arrive the assigned address of heart, because stopper angle can not regulate, can not well and heart atrial septal defect position coincide, affect its therapeutic effect.
Utility model content
The purpose of this utility model is to provide a kind of head end adjustable-angle seal wire, solves stopper and can not to coincide with heart atrial septal defect position well the technical problem causing therapeutic effect bad.
Above-mentioned technical purpose is solved for reaching, the utility model proposes a kind of head end adjustable-angle seal wire, seal wire comprises guidewire body and regulating handle, the front end of guidewire body is fixed with adjustment silk, regulate silk to be inlaid in guidewire body and stretch out from the rear end of guidewire body, extension connects with regulating handle.
Head end adjustable-angle seal wire as above, regulating handle comprises the load bearing seat installing guidewire body, and the end of load bearing seat is provided with tensioning member, regulates silk through load bearing seat and is fixedly connected with tensioning member.
Head end adjustable-angle seal wire as above, regulating handle comprises the revolving part be sleeved on outside tensioning member, and revolving part is sleeved on the end of load bearing seat, and revolving part inside coordinates with tensioning member outer surface thread.
The beneficial effects of the utility model are: the front end of this utility model guidewire body is fixed with adjustment silk.Wherein, regulate silk to be inlaid in guidewire body, and stretch out from the rear end of guidewire body, then stretch and regulate silk that the front end of guidewire body can be made to bend, thus regulate the angle of guidewire body front end, and then the angle of stopper and heart septal defect position are coincide, ensure therapeutic effect.By regulating silk stretching structure to regulate adjustment silk, can the operation of person greatly easy to use, improve Position location accuracy.Regulate the design of silk stretching structure can regulate more accurately the angle of guidewire body front end, result of use is very good.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of this utility model specific embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described:
A kind of head end adjustable-angle seal wire, comprises guidewire body 1, regulates silk 3 and regulating handle.
Wherein, be fixed with in the front end of guidewire body 1 and regulate silk 3, regulate silk 3 to be inlaid in guidewire body 1 and stretch out from the rear end of guidewire body 1.
Be connected with regulating handle in the rear end of guidewire body 1, regulating handle regulates silk 3, to regulate the angle of guidewire body 1 for stretching.
Wherein, regulating handle comprises the load bearing seat 4 installing guidewire body 1, and the end of load bearing seat 4 is provided with tensioning member 5, regulates silk 3 through load bearing seat 4 and is fixedly connected with tensioning member 5.
In the outer cover of tensioning member 5, revolving part 6 is housed, revolving part 6 is also sleeved on the end of load bearing seat 4, and revolving part 6 inside coordinates with tensioning member 5 outer surface thread.
During use, guidewire body 1 arrives heart atrial septal defect position, the revolving part 6 of regulating handle is utilized to rotate, thus drive tensioning member 5 away from load bearing seat 4, adjustment silk 3 is stretched, and then the angle of bend of the front end of guidewire body 1 is adjusted, until the angle of stopper is identical with the angle of heart septal defect position, then carry out ductus arteriosus occluder operation.After completing plugging operations, the revolving part 6 of regulating handle is rotated in the other direction, thus drive tensioning member 5 near load bearing seat 4, adjustment silk 3 is bounced back, and then the angle of bend of the front end of guidewire body 1 is restored, guidewire body 1 is taken out from human body.
In sum, this utility model can regulate the setting angle of stopper easily, reaches very perfectly therapeutic effect.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
