Abstract

The invention provides a kind of pre-knotted suture, including main line, sewing needle, stopper cylinder and cynapse；Wherein described cynapse is closely connected with main line.Its is green, and intensity is high, and durability is good, and without knotting, greatly saves operating time and reduce the health risk of patient.

Description

A kind of pre-knotted suture
Technical field
The invention belongs to medical applications technical field, in particular it relates to a kind of pre-knotted suture.
Background technology
Suture operation is the surgical procedures frequently used very much in operating room and ambulatory surgery operation.Although suture Using having there is very long history, but the blocking model of thread end not yet optimizes.Especially, for a line end is fixed to In partial biological tissue, typically same root line is knotted with itself, still, the knot substantially broken into when Between passage tend to untie automatically so that this blocking model is less reliable.For being proved to be necessary in surgical procedure For each sewing process, operator is forced to get the knot of high quantity successively.Therefore, performed by knot tying techniques Whole suture operation needs to spend one time that can not ignore to greatly affected the time span entirely treated, and can be to disease The health of people causes related harm.
The content of the invention
Goal of the invention：In order to overcome the above insufficient, the invention provides a kind of pre-knotted suture, its green ring Protect, intensity is high, and durability is good, and without knotting, greatly saves operating time and reduce the health risk of patient.
Technical scheme：In order to overcome the deficiencies in the prior art, the invention provides a kind of pre-knotted medical sutures Line, including main line, sewing needle, stopper cylinder and cynapse；Wherein described cynapse is closely connected with main line.
Further, a kind of above-mentioned pre-knotted suture, the sewing needle can be closely connected with main line head end, so The link of threading a needle in sewing process can be reduced, saves operating time；Stopper cylinder and main line tail end are closely coupled.
Further, above-mentioned a kind of pre-knotted suture, the stopper cylinder diameter are more than main line and sewing needle Diameter 0.5-1mm, can so prevent suture during pullling end unclamp cause suture fail.
Further, above-mentioned a kind of pre-knotted suture, the cynapse is in a manner of unilateral, polygon mode or along spiral Path is arranged on the main line, but the direction of cynapse can be so ensured after it has been gathered towards tail end by main line head end Without knotting, inverse cynapse can block body tissue surface completely, will not unclamp suture.
Further, above-mentioned a kind of pre-knotted suture, the sewing needle are C font flat sewing needles, so Inserting needle can be made in sewing process more easily laborsaving and facilitate operation surgical forceps to clamp sewing needle.
Further, above-mentioned a kind of pre-knotted suture, the main line, cynapse include following component：Group by weight Part meter,
Collagen：24-55 parts
Fibroin：23-56 parts
Fibroin：12-27 parts
Silk gum：13-23 parts
Glycolic：12-30 parts

Further, above-mentioned a kind of pre-knotted suture, described stopper cylinder include following component：By weight Component calculates,
Collagen：20-35 parts
Fibroin：10-36 parts
Fibroin：10-20 parts
Silk gum：10-20 parts
Glycolic：10-20 parts
Lactic acid：10-26.
Various formula constituent components are reasonable, green, and raw material sources are wide, are easily obtained, and production cost is low, is adapted to Large-scale industrial application.
Beneficial effect：Compared with prior art, the present invention has advantages below：A kind of pre-knotted of the present invention is medical Suture is green, and intensity is high, and durability is good, and without knotting, greatly saves operating time and reduce the strong of patient Health risk.And raw material sources are wide, are easily obtained, and production cost is low, are adapted to large-scale industrial application.
