Abstract

It is hanged the invention discloses a kind of band tooth pipe for plastic operation and carries 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 present invention is outstanding to carry 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

A kind of band tooth pipe is outstanding to carry line
Technical field
The present invention relates to medical instruments more particularly to a kind of the outstanding of plastic operation to carry line.
Background technology
With absorbable or the outstanding skin histology that carries of Absorption Line does not reach the existing applicating history for many years of face rejuvenation.It is acted on Principle is to carry the structural member that can reversely generate resistance in the outstanding wire body for carrying line, after sutured needle is conducted into facial tissue, instead To lifting, generated reversed resistance can drive tissue to be promoted, slight, moderate Aging damage appearance illness to reach treatment face Purpose.
It is this kind of it is outstanding carry line and be broadly divided into three classes for its structures and methods feature, one kind is reversely to generate the knot of resistance Component is formed to hang by the tooth that itself cutting generates in wire body carries line;Second class, which is that whole thermoplastic is outstanding, carries line, including entire section line Body and the structural member that can reversely generate resistance are all outstanding to carry line by what hot pressing or injection molding were formed;Third class is reversed energy What the structural member for generating resistance was that the conulite being hung in wire body is formed outstanding carries line.
This kind of hang that cutting forms tooth carries line, and wire body is orientated the sub-thread spinning threadling enhanced, the production of tooth to be stretched 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 carry line and enter tissue when, the direction-adapting of tooth walks direction, and crown is inserted into 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 carry 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 forms tooth with cutting carries line It is identical.
It is that the conulite through injection molding is hung in wire body that hollow cone is outstanding, which to carry line, and wire body can be stretched takes To and the sub-thread spinning threadling that enhances, can also be multiply litzendraht wire, and knot along this root wire body uniform intervals, hollow cone is fixed Between each two knot, the technology contents as disclosed in US7582105B2 and CN201404310Y.Lifting principle is carried when outstanding When line enters tissue, the smaller tip direction-adapting of cone walks direction, and the tail portion that cone is larger when reversely pulling generates reversed Resistance drives tissue to be promoted.
Outstanding regardless of structure carries line, and the size of power is most importantly lifted for lifting tissue.
Cutting forms the outstanding of tooth and carries 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 suitable The tiny position lifting little for pulling tension requirements.
Whole thermoplastic is outstanding to carry 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 that overstretching is orientated is compared to much smaller;Meanwhile to reach sub-thread spinning threadling equality strength and can process Property, it generally requires to increase wire body diameter, inflammatory reaction or patient's is uncomfortable caused by being likely to result in implantation material so too much Sense.
Hollow cone is outstanding to carry line, and wire body is also to be orientated the sub-thread spinning threadling enhanced or multiply litzendraht wire to be stretched, Intensity is larger, but conulite does not have the structure of tooth, only leans on the reversed resistance generation of cone to pull power, lifting dynamics is excessive When, there is the possibility of slippage.
Invention content
It in view of the above deficiency of the prior art, is hanged the object of the present invention is to provide a kind of band tooth pipe and carries line, the band tooth pipe is outstanding Carrying line has higher intensity, will not occur to be broken in lifting or slip.

The wire body is equipped with for limiting the knot with tooth pipe position;
The band tooth pipe includes hollow tube and is arranged in hollow tube outer wall and outwardly projecting tooth.
The band tooth pipe is outstanding to be carried line and is mainly formed by wire body and with tooth pipe, and wire body is orientated the sub-thread enhanced to be stretched Spinning threadling or multiply litzendraht wire have good wire body intensity;Its band tooth pipe is thermoplastic shaping, passes through the protrusion of tooth form on tube body Object realizes good tooth intensity, will not occur to be broken in lifting or slip.
Preferably, the band tooth pipe be two or more, the caliber at the hollow tube both ends it is identical or Close, the size of the knot is more than the internal diameter of hollow tube.
Preferably, the section of the tooth root of the tooth to crown is gradually reduced, the crown is along the hollow tube The axis of body is tilted to a side.
Preferably, each with tooth Guan Shangshe there are three or three or more teeth, the crown inclined direction phase of all teeth Together.
In the present invention, the tooth is in any position of hollow tube wall, preferably, any two tooth is not in hollow tube wall On the same circumference.
In the band tooth pipe, circumferentially at any angle between two tooth.Preferably, in described There are three teeth outside blank pipe body, circumferentially at hexagonal angle degree between each of which tooth.
Preferably, along the hollow tube axial direction between two neighboring tooth (5) on the same hollow tube Distance is 0-5mm.
Preferably, the length of the tooth root of the tooth to crown is no more than 5mm, the tooth root of the tooth is along described The width of hollow tube axial direction is 0.1-4mm, the tooth root of the tooth along the thickness of the hollow tube circumferential direction for more than 0.2mm。
Preferably, the gradient of the crown of the tooth, which is the 10-80 ° of angle, substantially refers to that denticle is carried with hollow tube Axial angle.
Preferably, the knot being distributed in wire body can be wire body itself knot, or the knot of welding up, two knots it Between distance can arbitrarily adjust.
The band tooth pipe of the present invention is outstanding to carry line, wherein the stretched orientation of the wire body absorbable material or multiply are compiled It knits;The band effective absorbable material of tooth is made by injection molding.Absorbable material includes:L- lactides, DL- lactides, Glycolide, caprolactone, trimethylene carbonate, the homopolymer of Lanthanum Isopropoxide or copolymer, homopolymer or copolymer are total to Mixed object.
