Description
Technical field
The utility model relates to medical guiding wire technical field, especially a kind of end gradation type medical guiding wire.
Background technique
The use of medical guiding wire clinically is very frequent, such as the puncture of anesthetic tube, the insertion of stomach tube, can all use
To medical guiding wire.Most of medical guiding wire hardness is big at present, and the head and tail portion of core filaments are not soft enough as the inlet of seal wire
It is soft, it in operative process, be easy to cause and wears out some important tissues, increase the resistance for importing human body, influence just
Normal surgical procedure.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of end gradation type medical guiding wire, increase the flexible of medical guiding wire
Property, the smooth of process is facilitated insertion into, the risk of prick into human body is prevented, guarantees safety.
The utility model embodiment provides a kind of end gradation type medical guiding wire, and the both ends of the medical guiding wire form two
Tip, the tip include along medical guiding wire tactic first boss, second boss, third boss and the 4th axially outward
Boss, the first boss, second boss, third boss and the coaxial arrangement of the 4th boss and first boss, second boss, third
The radius of boss and the 4th boss is sequentially reduced, and the circumferential surface of the first boss is formed to curved first cambered surface of second boss,
The circumferential surface of the second boss is formed to curved second cambered surface of third boss, and the circumferential surface of the third boss forms convex to the 4th
Curved 4th cambered surface of platform, the circumferential surface of the 4th boss are formed to curved 4th cambered surface in its end face, first cambered surface,
Two cambered surfaces, third cambered surface and the 4th cambered surface are sequentially connected, and the end face of the 4th boss is equipped with cabochon round end.
Preferably, the radius of the first boss, second boss, third boss and the 4th boss is in arithmetic progression.
Preferably, the radius of the first boss is 0.2mm, first boss, second boss, third boss and the 4th boss
Between radius tolerances be 0.05mm.
Preferably, the radius of the medical guiding wire is 0.25mm.
Preferably, first cambered surface, the second cambered surface, third cambered surface are identical with the radius of curvature of the 4th cambered surface.
Preferably, the round end is hemispherical.
In the utility model, the both ends of medical guiding wire form the gradually smaller first boss of radius, second boss, third
Boss and the 4th boss form step-wise transition, gradually increase the flexibility of end, meanwhile, the circumferential surface of each boss forms arc
The cambered surface in face, boss is also connected with each other, and keeps the tip of medical guiding wire more smooth submissive, makes the process of medical guiding wire insertion human body
It is more smooth, the risk of prick into human body is reduced, ensure that safety.
Detailed description of the invention
Fig. 1 is a kind of diagrammatic cross-section of embodiment of the utility model.
Specific embodiment
The utility model embodiment provides a kind of end gradation type medical guiding wire, as shown in Figure 1, the medical guiding wire can be used
Metal material is made, whole to have certain flexibility.The medical guiding wire includes main part 1 and is arranged at 1 both ends of main part
Two tips 2, tip 2 includes that the first boss 31, second boss 32, third that are linked in sequence axially outward along medical guiding wire are convex
Platform 33 and the 4th boss 34, on the basis of not considering cambered surface hereafter, first boss 31, second boss 32, third boss 33
It is cylindrical with the 4th boss 34, such as the dotted line signal in figure.First boss 31, second boss 32,33 and of third boss
The coaxial arrangement of 4th boss 34, and it is coaxial with the axle center of main part 1.First boss 31, second boss 32, third boss 33 and
The radius of four boss 34 is sequentially reduced, and cross sectional shape is stepped.Since radius sequentially reduces, size is thinner, will increase greatly
Add the flexibility of medical guiding wire end.Meanwhile in order to guarantee that whole structural strength, main part 1, first boss 31, second are convex
Platform 32, third boss 33 and the 4th boss 34 are integrated moldings.
On the basis of this structure, the circumferential surface of first boss 31 is formed to curved first cambered surface 41 of second boss 32, institute
The circumferential surface for stating second boss 32 is formed to curved second cambered surface 42 of third boss 33, the circumferential surface of the third boss 33 formed to
Curved 4th cambered surface 43 of 4th boss 34, the circumferential surface of the 4th boss 34 are formed to curved 4th cambered surface 44 in its end face,
First cambered surface 41, the second cambered surface 42, third cambered surface 43 and the 4th cambered surface 44 are sequentially connected, and the first cambered surface 41 is from main part 1
Circumferential surface is bent to the second cambered surface 42, and the end face of the 4th boss 34 is equipped with cabochon round end 30.So that tip 2 is from round end 30 to whole
A circumferential surface, which is arc-shaped, to smoothly transit, and on the one hand will not scratch tissue, on the other hand makes the process of seal wire insertion human body more
Add smooth.
In one embodiment, the first boss 31, second boss 32, third boss 33 and the 4th boss 34 radius
In arithmetic progression.For example, the radius of first boss is 0.2mm, the radius of second boss is 0.15mm, and the radius of third boss is
0.1mm, the radius of the 4th boss are 0.05mm.The structure of this arithmetic progression makes first boss 31, second boss 32, third
Staged gradual change held stationary between boss 33 and the 4th boss 34 is not in the mutation of radius, guarantees 2 entirety of tip
It is smooth smooth.Further, the radius of medical guiding wire, the i.e. radius of main part 1 are 0.25mm, then main part 1, first boss
31, the radius of second boss 32, third boss 33 and the 4th boss 34 is in arithmetic progression.
In one embodiment, first cambered surface 41, the second cambered surface 42, the curvature of third cambered surface 43 and the 4th cambered surface 44
Radius is identical, also makes the gradual change held stationary of circumferential surface, is not in the too large or too small mutation of radian.
In one embodiment, the round end 30 is hemispherical, keeps transition more steady smooth.
In one embodiment, the surface of medical guiding wire is also wrapped on protective layer, protective layer can using PTFE coating or
Hydrophilic coating is made, and can protect medical guiding wire and is not damaged.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made.
