But, exactly concerning the operator that possesses superb manual knotting technical ability, owing to be subjected to the spatial restriction of wound site, especially vision can not or the wound site of very difficult arrival especially fixedly implement manual knotting during the ossiculum folded block, also will produce the problem of knotting (being that operation suture thread is not taken out tightly) not in place inevitably, so that influence the normal healing of wound or fracture.Particularly when the stitching of the outstanding thick big wound of human abdomen's fat deposit, often must cooperate under the tractive condition, could finish preferably the assistant.This shows that the surgical sewing thread of prior art is linked to be many troubles such as time-consuming, effort to clinical operation, also caused adverse effect by the wound of operator or union of fracture.

Summary of the invention

The purpose of this utility model is to provide a kind of button knot time saving and energy saving, convenient easy surgical sewing thread, to overcome the deficiency of prior art.

The technical scheme that realizes the purpose of this utility model is, a kind of surgical sewing thread, comprise surgical thread, one end of surgical thread can be connected with operation needle, its improvement is: the other end at surgical thread is provided with and surgical thread interconnection all-in-one-piece snap close, snap close with can be connected between the operation needle end and line segment near the surgical thread of snap close on, be provided with several alternate layouts and with surgical thread interconnection all-in-one-piece button piece; The smaller diameter end of button piece is pointed to the end that can establish operation needle; Snap close and button piece be mutually can be unidirectional the button knot of button knot secondary.

Technical scheme by above given realization this utility model purpose can be understood, as long as being driven surgical thread, operation needle passes snap close, spur surgical thread then, can tie pair by the button that the unidirectional button that snap close and button piece constitute is tied, and finish the task of button knot quickly and easily; Also snap close can be cut off by cutting on the surgical thread, tail end with surgical thread passes snap close then, operator one finger-tight surgical thread tail end, on the other hand advance snap close and make snap close one by one by the button piece until the task of finishing the button knot, thereby make traditional craft knotting be improved to the mechanical clasps knot, realized the purpose of this utility model.

Further improvement of the utility model point also is:

Said can be unidirectional the secondary included snap close of button knot of button knot be circular cone shape, be provided with conical through-hole in the central authorities of snap close, the minor diameter of conical through-hole is slightly less than or equals the external diameter of surgical thread; On the perisporium of snap close smaller diameter end, be provided with axial crack groove; Axially the crack groove extends to the axial middle part of snap close by smaller diameter end to larger diameter end, thereby makes snap close constitute elastic lock; Said button piece is circular cone shape and is mutually with conical through-hole that snap close is had and is slidingly matched; Thereby make snap close and button piece be mutually can be unidirectional the button knot of button knot secondary.

More than given button that can unidirectional button knot tie subsidiary technical scheme, be the special recommendation of this utility model institute.This is because it is not only simple in structure, and because snap close is an elastic lock, and when practical operation, snap close is light by the button piece, put in place, and unidirectional button knot is firmly reliable.Certainly, button of unidirectional locating button knot is tied auxiliary structure form (as shown in Figure 6) such as having the tight surgical thread of the direct pawl of localizer (especially pigtail shape suture) that pawl refers in the apportion also can to adopt other.But the technical scheme that its effect is recommended than this utility model is a little bit poorer.This this utility model is not very advocated.

Several button pieces axially equidistantly distribute along surgical thread, or either large or small the distribution.Its purpose obviously is in order to further facilitate the enforcement of operation button knot.

Adjacent two button pieces along the axially mutual spacing of surgical thread in 2～10mm scope.This is that the applicant is by repeatedly practising the spacing of given clinical practice.The spacing that particularly is located at adjacent two the button pieces of front end is preferably smaller, or the spacing of adjacent two button pieces is progressively dwindled by rear end to front end.Can further facilitate the adjusting that puts in place when being on the verge of to detain the knot end like this.

Surgical thread, snap close and button piece are that the commaterial that can be held by the animal body tissue is made into integration, thereby make surgical thread be mutually one with snap close, button piece respectively.

After this utility model technique scheme is implemented, what it had changes the mechanical clasps knot into by the knotting of operator maneuver, and button is tied, and time saving and energy saving, convenient easy effect and effect are conspicuous, and have tangible positive effect for improving the operation stitching soft tissue with the quality of tying up little sclerite.
