It is hanged the utility model discloses a kind of band tooth pipe for plastic operation and mentions line, including wire body, the multiple knots being distributed in wire body, string has band tooth pipe between knot in wire body, band tooth pipe is hollow tube, hollow tube outer wall be equipped with one or more, two or more, three or three or more project radially out tooth outside tube body；It the wire body and is made with the effective absorbable material of tooth.The band tooth pipe of the utility model is outstanding to mention line, it has good wire body intensity, while also having good tooth intensity；By the protrusion with tooth form, increase Junctional tissue, so that lifting power greatly improves.
Description
Technical field
The present invention relates to medical instruments more particularly to a kind of the outstanding of plastic operation to mention line.
Background technique
With absorbable or the outstanding skin histology that mentions of Absorption Line does not reach the applicating history that face rejuvenation has many years.It is acted on
Principle is to have the structural member that can reversely generate resistance in the outstanding wire body for mentioning line, after sutured needle is conducted into facial tissue, instead
To lifting, generated reversed resistance will drive tissue promotion, hold illness to reach facial slight, the moderate Aging damage for the treatment of
Purpose.
It is this kind of it is outstanding mention line and be broadly divided into three classes for its structures and methods feature, one kind is the knot that can reversely generate resistance
Component is formed to hang by the tooth that itself cutting generates in wire body mentions line；Second class, which is that whole thermoplastic is outstanding, mentions line, including entire section line
Body and the structural member that can reversely generate resistance are all that formed by hot pressing or injection molding outstanding mentions line；Third class is reversed energy
The structural member for generating resistance is to hang to mention line composed by the conulite that is hung in wire body.
This kind of hang that cutting forms tooth mentions line, and wire body is the sub-thread spinning threadling of stretched orientation and enhancing, the production of tooth
Life is to cut wire body itself along some direction and form many pawls, the barbed suture as disclosed in CN101027168A.
Lifting principle is: when it is outstanding mention line and enter tissue when, the direction-adapting of tooth walks direction, tooth tip insertion tissue and produces when reversely pulling
The raw power that pulls can promote tissue.
It is that many pawls are formed in wire body by hot pressing or injection moulding process that whole thermoplastic is outstanding, which to mention line, and tooth is grown from wire body
And one is formed with wire body, it does not cut, such as the fish-bone line of Johson & Johnson.This kind of hang that lifting principle and cutting form tooth mentions line
It is identical.
It is that the conulite through injection molding is hung in wire body that hollow cone is outstanding, which to mention line, and wire body can be stretched take
To and the sub-thread spinning threadling that enhances, be also possible to multiply litzendraht wire, and knot along this root wire body uniform intervals, hollow cone is fixed
Between every two knot, the technology contents as disclosed in US7582105B2 and CN201404310Y.Lifting principle is mentioned when outstanding
When line enters tissue, the lesser tip direction-adapting of cone walks direction, and the biggish tail portion of cone generates reversed when reversely pulling
Resistance drives tissue to be promoted.
Outstanding regardless of structure mentions line, and the size of power is most importantly lifted for lifting tissue.
Cutting forms the outstanding of tooth and mentions line, since denticle is not hard enough, is easily deformed, overturns or is broken when reversely pulling, because
The lifting intensity of this tooth is also minimum；Meanwhile wire body is due to by cutting damage, tensile strength also very little is easy to be pulled off, only fit
The tiny position lifting little for pulling tension requirements.
Whole thermoplastic is outstanding to mention line, and since tooth is more thick and solid, lifting intensity is larger, but the tensile strength of wire body and the warp with diameter
The sub-thread spinning threadling of overstretching orientation is compared to much smaller；Meanwhile to reaching sub-thread spinning threadling equality strength and caning be processed
Property, it generally requires to increase wire body diameter, inflammatory reaction or patient's caused by being likely to result in implantation material so too much is uncomfortable
Sense.
Hollow cone is outstanding to mention line, and wire body is also the sub-thread spinning threadling or multiply litzendraht wire that enhance for stretched orientation,
Intensity is larger, but conulite does not have the structure of tooth, only pulls power by the reversed resistance generation of cone, lifting dynamics is excessive
When, there is the possibility of slippage.
