Abstract
A kind of minimally invasive elevator belt of face of present invention offer, its moulding process and its working method, the minimally invasive elevator belt of face includes the elongated straps body for having thickness, multiple connecting holes are distributed on the one side with body, multiple protrusions for being pierced into facial fascia superficialis system are distributed on another side.The present invention provides a kind of minimally invasive elevator belts of face simple in structure, easy to use, good fixing effect, and compared with prior art, the present invention solves and stays the end of a thread and fixed unstable clinical problem after current hangnail line suspends in midair.
Description
Technical field
The present invention relates to a kind of plastic operation materials, and in particular to a kind of minimally invasive elevator belt of face, its moulding process and its
Working method.
Background technology
With advancing age, face appearance relaxes, is sagging, and specific manifestation goes out tissue recess, tissue moves down accumulation, elasticity
The clinical symptoms such as reduction, wrinkle increase.It is a kind of common medical hand in beautifying face plastic operation that face crinkle-removing, which promotes operation,
Then art arrive nonabsorable material from traditional Tossed Mung Clear Noodles in Sauce operation to the promotion art of mini-invasive incision, then arrive PDO, PPDO,
PLLA etc. can be a quantum leap of medical cosmetology technology by the material implantation that body tissue is metabolized, and it is small, extensive that technology possesses wound
It answers advantages, the clinics such as fast, effect duration is long, can be implanted into repeatedly and is able to extensive utilization.But mini-invasive incision, which promotes art, is
Various suspention lines are implanted between facial skin and muscle by minimally invasive method, to the relative position of facial muscles and skin
It is adjusted, to achieve the purpose that wrinkle removal beauty treatment, although wound is small, the guiding needle due to burying suspention line at present is straight
Needle, therefore the suspention line being embedded between skin and muscle is also linearly to be distributed, so the position of suspention is single point, is drawn
Position be also local, cannot achieve the purpose that integrally to improve, overall effect unobvious.
For this purpose, clinic is highly desirable to a kind of better implantation instrument of minimally invasive fixed effect and method.
Invention content
The technical problem to be solved in the present invention is to provide a kind of minimally invasive elevator belt of face, its moulding process and its work sides
Method, simple in structure, easy to use, good fixing effect solve to stay the end of a thread and fixation insecure after current hangnail line suspention
Clinical problem.
In order to solve the above technical problems, the embodiment of the present invention provides a kind of minimally invasive elevator belt of face, including has thickness
Multiple connecting holes are distributed on the one side with body in elongated straps body, and it is shallow that multiple piercings faces are distributed on another side
The protrusion of fascia system.
Wherein, the connecting hole is through the through-hole with body.
Further, the structure snd size of each protrusion with side side are identical, and it is described protrusion have can be inserted into through-hole
And with the structure snd size of through-hole close-fitting.
The structure snd size of the protrusion with side side can also be different, multiple protrusions point with side side described at this time
For the first bonding pad protrusion and the first lifting zone protrusion, first bonding pad protrusion have can be inserted into through-hole and with through-hole close-fitting
Structure snd size.
Wherein, the connecting hole with one side of body is blind hole.
If the blind hole overlaps in the axial direction with the protrusion with another side of body, at this point, if the depth of the blind hole
More than the thickness with body, the structure snd size of the protrusion with side side cannot be all identical, then described with side side
Protrusion be divided into the second bonding pad protrusion and the second lifting zone protrusion, second bonding pad protrusion have can be inserted into blind hole and with it is blind
The structure snd size of hole close-fitting.If the depth of the blind hole is less than the thickness with body, the structure of the protrusion with side side
Also cannot be all identical with size, the protrusion with side side is divided into third bonding pad protrusion and third lifting zone protrusion,
Third bonding pad protrusion have can be inserted into blind hole and with the structure snd size of blind hole close-fitting.
If the blind hole and the protrusion with another side of body are misaligned in the axial direction.At this point, if the depth of the blind hole
Degree is more than the thickness with body, and the structure snd size of each protrusion with side side can be identical, and the protrusion has and can insert
Enter blind hole and with the structure snd size of blind hole close-fitting.The structure snd size of each protrusion with side side can not also all phases
Together, the protrusion with side side described at this time is divided into the 4th bonding pad protrusion and the 4th lifting zone protrusion, and the 4th bonding pad is convex
Rise have can be inserted into blind hole and with the structure snd size of blind hole close-fitting.
If the depth of the blind hole is less than the thickness with body, the structure snd size of each protrusion with side side cannot
All identical, the protrusion with side side described at this time is divided into the 5th bonding pad protrusion and the 5th lifting zone protrusion, the 5th connection
Area's protrusion have can be inserted into blind hole and with the structure snd size of blind hole close-fitting.
Wherein, the lower end outside of the protrusion is equipped with hangnail.
Wherein, the width with body is 0.01mm-100mm, thickness 0.01mm-10mm.
