Description
Technical field
The utility model belongs to medical device fields, is related to therapeutic medical suture, relates more specifically to a kind of medical seam
Zygonema.
Background technique
Operation suture thread finds most common use in the medical procedure of wide scope, by the group of human body be woven in due to wound evil or
It performs the operation and cuts off and keep together later.In addition to being used as tissue fastener, suture and other elongated linear medical devices
It also acts as organization bracket or structural support and is used to grow new tissue or during this period at the targeted tissue sites of patient
It uses.
Surgical suture can be divided into the absorption that is decomposed in vivo absorbable sutures and in vivo not by
Decompose the nonabsorbable suture absorbed.The absorbable sutures and nonabsorbable suture are according to during operative site or suture
Deng and be used separately.Nonabsorbable suture has required stable tensile strength in operation, but has the disadvantage that:
Re-treatm ent is needed to remain in the intracorporal suture of biology as foreign matter using after Removal.In contrast, absorbable sutures by
It is absorbed in vivo after operation, therefore does not need re-treatm ent.But according to operative site, due to being acted on after operation
The external force at the position is different, and therefore, it is necessary to control the tensile strength of suture according to purpose to change with time: decomposing speed
Degree.In order to which ligaturing the position always until operative site is cured, it is necessary to have defined tensile strength, it is preferred that
Be the suture that is controlled of decomposition rate to make it be decomposed while operative site is cured.Ideal suture in addition to
Have regulatable absorbability, insignificant toxicity, mechanical strength that can be lasting, good flexibility, resistant to the sterilising, easily sterilizing
Outside, should also have the function of antibacterial and treatment.By antibiosis anti-inflammatory drug, anodyne or other such as anticarcinogens of drug with therapeutic effect
Or bioactive substance (such as growth factor) is introduced into inside the suture with regulation tensile strength or surface, to eliminate wound
Infection promotes wound healing, reduction of patient pain, is an important development direction of suture.Common method be by
Drug is applied directly to suture surface, though to control postoperative infection have certain effect, be difficult to realize drug by controlled release
It puts.
Utility model content:
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of suture.
The technical solution that the utility model is taken to achieve the goals above are as follows:
A kind of suture, which is characterized in that it is shell with outer surface and inner core, the outer surface, described interior
Core is sandwich layer, and the sandwich layer is made of a concentric inner region；The shell is arranged radially at the same of inner core by multiple
Heart perimeter；The shell layer surface is equipped with the channel by load bioactive ingredients, and the channel is by bioactive ingredients
It is immersed in suture, the sandwich layer is hollow structure or solid construction.
Further, the channel of the shell layer surface use porous structure, it is described it is porous be set as several, the porous edge
Shell layer surface is twist distributed or linear type distribution, and the sandwich layer is hollow structure.
Further, the channel of the shell layer surface uses scalloped recess structure, and the sandwich layer is hollow structure, wherein hollow
Being integrally connected for structure and groove, makes suture at c-type structure.
Further, the channel of the shell layer surface uses curved groove structure, there are two wherein arc groove is set, symmetrical point
For cloth in shell layer surface, the sandwich layer is solid construction.
Further, the diameter 0.3mm of the suture.
Further, the material of the suture is memory metal, and the memory metal is Ti-Ni alloy.
Further, the bioactive substance be by wound suture to human body generation effect drug growth because
Son.
The utility model has the following beneficial effects: the utility model memory metal suture have it is applied widely, with people
Body it is affinity can and the superior function without rejection, have regulation absorbability, can be lasting mechanical strength, good
Flexibility should also have the function of antibacterial and treatment, can sew up a wound and can be reduced infection.There are also include following advantage simultaneously:
1. making it have reminiscence since suture uses Ti-Ni alloy memory metal, can be very good to restore chamber
Road shape keeps water conservancy diversion unimpeded, keeps rectilinear form, can accelerate wound healing to wound persistent pressure.
2. Ti-Ni alloy memory metal does not have bioactivity, it is possible to reduce the allergic reaction of biomaterial.
4. wound is straightened or is drained wound fester everywhere by memory metal, accelerate wound healing, reduces scar.
5. memory metal as external suture, is taken out stitches simply, it can voluntarily take out stitches, be reduced to the trouble of hospital.
6. overstriking memory metal suture has bigger drawing force, preferably wound will be pressed together, preferably
Promote wound healing.
