Abstract
This utility model relates to technical field of medical instruments, particularly relate to a kind of suture, this stitching thread is provided with chitosan nano fiber bundle, described sutural cross section is regular polygon, described stitching thread is provided with an end, this end is the regular polygon identical with described stitching thread axis, the length of side of the cross section regular polygon of described end is greater than the length of side of described sutural cross section regular polygon, solve existing sutural fracture strength lower, absorption phase is long, suture normally will be tied a knot at self with single line with it, the knot broken into easily automatically is untied thus needed to get more knots increases treatment time problem.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of suture.
Background technology
At present, medical operation suture thread is mainly divided into two classes, and a class is non-absorbent stitching thread, and such stitching thread Post operation needs to take out stitches, cumbersome; Another kind of is absorbable stitching thread, and that commonly uses now has suture of amniotic membrane, PGA (polyglycolic acid), PGLA (polylactic-co-glycolic acid) etc., but there is certain deficiency in these materials, sutural fracture strength is lower, and absorption phase is long, has certain zest etc.
In operating room and outpatient clinic's surgical operation, suture normally will be tied a knot at self with single line with it, but, the knot broken into tends to automatically untie as time goes by, in operation process, force operator must get the knot of high quantity successively like this, by the time that whole sew application of tiing a knot needs cost longer, this have impact on the time of whole treatment widely, and can cause relevant harm to the health of patient.
Utility model content
The technical problems to be solved in the utility model is: lower in order to solve existing sutural fracture strength, absorption phase is long, stitching thread easily skids, suture normally will be tied a knot at self with single line with it, the knot broken into easily automatically is untied thus needed to get more knots increases treatment time problem, this utility model provides a kind of suture, described stitching thread is provided with chitosan nano fiber bundle, described sutural cross section is regular polygon, described stitching thread is provided with an end, this end is the regular polygon identical with described stitching thread axis, the length of side of the cross section regular polygon of described end is greater than the length of side of described sutural cross section regular polygon, solve existing sutural fracture strength lower, absorption phase is long, stitching thread easily skids, suture normally will be tied a knot at self with single line with it, the knot broken into easily automatically is untied thus needed to get more knots increases treatment time problem.
This utility model solves the technical scheme that its technical problem adopts:
A kind of suture, comprise stitching thread and sewing needle, described stitching thread comprises chitosan nano fiber bundle, the elastic fibrous layer of the some strands of spiral windings that shuffling has and the hemostasis and anti-inflammation layer that is provided with on elastic fibrous layer on described chitosan nano fiber bundle, described sutural cross section is regular polygon, described stitching thread is provided with an end, this end is the regular polygon identical with described stitching thread axis, and the length of side of the cross section regular polygon of described end is greater than the length of side of described sutural cross section regular polygon.
Particularly, the thickness of described end is 1 ~ 3mm.
Particularly, described stitching thread is connected with described sewing needle one.
Particularly, the thickness of described hemostasis and anti-inflammation layer is 0.5 ~ 1um.
The beneficial effects of the utility model are: this utility model provides a kind of suture, described stitching thread is provided with chitosan nano fiber bundle, described sutural cross section is regular polygon, described stitching thread is provided with an end, this end is the regular polygon identical with described stitching thread axis, the length of side of the cross section regular polygon of described end is greater than the length of side of described sutural cross section regular polygon, solve existing sutural fracture strength lower, absorption phase is long, stitching thread easily skids, suture normally will be tied a knot at self with single line with it, the knot broken into easily automatically is untied thus needed to get more knots increases treatment time problem.
