Abstract
The invention discloses a controllable absorptive medical mending mesh, which is formed by PGA and PGLA. The mending mesh has excellent tissue compatibility with human body tissues, and different degrading and absorbing periods of the two PGA and PGLA substances are advantageous to quick growth of the tissues, so the mending mesh is finally degraded and absorbed by the human body completely. Different weaving structures can be selected according to positions in use so as to determine the degrading and absorbing time and meet the requirement of tissue growth. In the mending mesh, the netting has stable flattening performance, is more compliant, flat and attachable to the structure of the human body, and can be cut into any required shape.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to the repairing net in the medical instruments field.
Background technology
At present, medical repairing net has two types material, a kind of be with polypropylene etc. not absorbable material make, the operation back is just stayed in the human body forever, exists following problem: at first, when being used for stomach wall holostrome defect repairing, mending net will isolate with viscera tissue, if it directly contacts with internal organs and can cause more serious abdominal adhesions, digestive tract blocks, even may corrode intestinal wall, cause intestinal fistula; Secondly, repair if carry out large-area abdominal-wall defect, the cicatrix contraction in later stage can cause the distortion of net sheet, and its irregular surface may stimulate and damage surrounding tissue, causes infection, causes the skin sinus tract to form.Second kind is to make with PGA human body absorbable material, the time cycle of this kind absorbed is about 60～90 days, that is to say to have only and just can be absorbed to official hour, the defective that exists is: after operation in the tissue growth process, especially later stage, tissue is influenced its healing rate owing to fetter.
Summary of the invention
The technical problem to be solved in the present invention provides the medical repairing net of a kind of controlled absorbed, make the material of this repairing net, because absorption cycle difference, be beneficial to the growth of operation back tissue, especially perform the operation the later stage, a kind of material wherein is organized absorption fully, and the medical repairing web frame of this moment is loose, mesh is big, tissue is unfolded, and healing rate is fast.
The present invention is achieved through the following technical solutions:
The medical repairing net of a kind of controlled absorbed, described repairing net is made of PGA and PGLA.
The further improvement project of the present invention is, PGA, PGLA spinning respectively, and both are intervally arranged with 1:0.2-5 and are made into the repairing net.
The further improvement project of the present invention is that the warp thread of repairing net or weft yarn are intervally arranged with 1:0.2-5 respectively and weave; Or warp thread is intervally arranged with 1:0.2-5 and weaves, or weft yarn is intervally arranged with 1:0.2-5 and weaves.
The further improvement project of the present invention is, PGA, PGLA are made into the repairing net after with 1:0.2-5 blend spinning.
Or PGA and PGLA be with 1:0.2-5 blend spinning, and the single yarn of PGA or PGLA and PGA and PGLA blended yarns are made into the repairing net with 1:0.2-5.
Described 60～90 days PGA polyglycolic acid synthetics absorption of human body cycles.
Described 56～70 days PGLA polymeric polyglycolide-polylactide synthetics absorption of human body cycles.
The present invention compared with prior art has the following advantages:
The present invention and tissue have the favorable tissue compatibility, decomposition, absorption cycle that two kinds of materials of PGA/PGLA are different, be beneficial to the quick growth of tissue, and repair net and finally decomposed absorption by human body fully.
Can select different braiding structures according to the position in the use,, satisfy the needs of tissue growth to determine decomposing soak time.
The present invention repairs net, and its net sheet has stable open and flat performance, more obeys, smooth, applying organization of human body, and can cut randomly into required form.
