Embodying the exemplary embodiment of the utility model feature and advantage will describe in detail in the following description.It should be understood that
Be that the utility model can have various changes in different embodiments, it does not all depart from model of the present utility model
Enclose, and explanation therein and diagram are treated as purposes of discussion in itself, and be not used to limit the utility model.
In order to further illustrate principle of the present utility model and structure, it is preferable to carry out in conjunction with accompanying drawing to of the present utility model
Example is described in detail.
The utility model is when describing orientation, using the operator of guiding wire as object of reference, one end of close operator, i.e.,
Operator promotes one end of guiding wire to be near-end, and opposite one end is then distal end.
Refering to Fig. 1, the guiding wire of the present embodiment includes main mandrel 11, traction element 12, seal wire outer layer 13, spring protecting sleeve
14 and termination 15.
Main mandrel 11 is included pushing section 111, supporting section 112, connection tip 113 and soft tip successively by near-end to distal end
114。
Bar segment 111 is pushed to be used for pushing supporting section 112, connection tip 113 and soft sophisticated 114 movement in the blood vessels.
The connection of supporting section 112 pushes bar segment 111 and connection tip 113, and in the presence of the power of bar segment transmission is pushed
Promote connection tip 113 and soft sophisticated 114 traveling in the blood vessels.
Connection tip 113 is prolonged axis direction and is tapered, the support force intravasation for receiving the offer of supporting section 112.
Soft tip 114 is prolonged axis direction and is tapered, and the support force for receiving the transmission of connection tip 113 enters blood
Pipe.
The main material of mandrel 11 is Nitinol or stainless steel, with good buckle resistance, pushability, it is ensured that lead
The pushability of silk 1, support force.
Spring protecting sleeve 14 is sheathed on the distal end of main mandrel 11.Spring protecting sleeve 14 is close to one end of the near-end of the main mandrel 11
Weld together with main mandrel 11.Spring protecting sleeve 14 can improve the flexibility of the distal end of guiding wire 1, so that unlikely damage human body
Tissue, while the touch feedback of operator can be improved, improves the operating characteristics of guiding wire 1.
Specifically in the present embodiment, the diameter of spring protecting sleeve 14 is consistent with the diameter of the main mandrel of near-end 11.By Nitinol
Silk or stainless steel wire coiling are formed.
Seal wire outer layer 13, is wrapped in outside main mandrel 11.Seal wire outer layer 13 can increase guiding wire 1 by property, drop
Low friction.Seal wire cladding material can be polyamide, polyurethane, polyethylene, polypropylene and their composite.
Passage is offered inside seal wire outer layer 13, the proximal openings 131 of passage are located at the proximal end of seal wire outer layer 13, lead to
The distal openings 132 in road are located on the side of seal wire outer layer 13.
Specifically in the present embodiment, distal openings 132 are located at seal wire outer layer 13 at termination 20cm ~ 100cm.
Termination 15, is welded in the distal end of the seal wire outer layer 13.Termination 15 is Nitinol head.
The profile of termination 15 is hemispherical.Termination 15 uses hemispherical curved surface, contributes to guiding wire 1 to enter tissue,
Strengthen guiding wire 1 by property, do not damage tissue.
In traction element 12, the passage for being contained in seal wire outer layer 13.The length of traction element 12 is more than the length of main mandrel 11
Degree.
Refering to Fig. 2, Fig. 3, one end of traction element 12 is passed in proximal openings 131, and the other end is worn in distal openings 132
Go out, and be close to the outer wall of seal wire outer layer 13, weld together with termination 15.
The material of traction element 12 is Nitinol or stainless steel, with good buckle resistance, pushability, it is ensured that traction
Pushability, bend resistance power of the part 12 in movement.
Guidewire lumen 16 is interior hollow-core construction, in the passage of seal wire outer layer 12, is sheathed on traction element 12.For
Bottom offset thereon is controlled when traction element 12 is moved.
There is traction element, when operation needs guiding wire 1 to bend certain angle inside guiding wire of the present utility model
When, the near-end of fixed main mandrel 11 prolongs the axis direction of traction element 12, slowly pulls at the proximal tips of traction element 12,
Traction element 12 is set proximally to be moved by distal end.Now, the distal end of traction element 12 drives the distal end of main mandrel 11 to be allowed to
Slowly bend, reach required angle, guiding wire is quickly passed through, reach appointed part.
It can be seen that, guiding wire of the present utility model is by pulling traction element come adjustable guide wire distal angle, you can
Guiding wire is saved into the seal wire molding step before human body, guiding wire is quickly reached specifying part while distal end can be regulated and controled again
Position, shortens operating time, reduces operation risk, reduction patient's pain.
Although describing the utility model with reference to several exemplary embodiments, it is to be understood that, term used is to say
Bright and exemplary and nonrestrictive term.Because the utility model can be embodied without departing from practicality in a variety of forms
New is spiritual or substantive, it should therefore be appreciated that above-mentioned embodiment is not limited to any foregoing details, and should be in right of enclosing
It is required that widely explained in the spirit and scope limited, thus whole changes for falling into claim or its equivalent scope and
Remodeling all should be appended claims and be covered.
