The suture line has simple structure, convenient use and operation time saving, and can be widely used for suturing various surgical soft tissues.
Description
Technical Field
The utility model relates to a medical treatment operation stylolite especially relates to an one-way barb exempts from stylolite of knoing.
Background
The existing knotting-free suture line is generally realized by uniformly distributing barbs on a line body, and is divided into a unidirectional barb line and a bidirectional barb line, so that the concept that the traditional suture needs to be knotted is changed, the use is convenient, the trouble is saved, and the operation efficiency is improved.
The existing one-way barb suture line is formed by uniformly cutting a plurality of fishbone barbs on a smooth cylindrical suture line, wherein the fishbone barbs are distributed along an axial 360-degree three-dimensional spiral shape, one end of the suture line is connected with a suture needle, the other end of the suture line is fixed with a coil or a wing piece, the needle falls from one end of a wound during suture, the suture needle penetrates through the coil, is tensioned and fixed or fixed by the wing piece, then is sutured towards the other end, and the suture line is cut off after the suture is finished.
Because the suture has barbs and can only be tightened in one way and cannot be retracted, once the suture is inserted and led out, the situation that the stay wire is too tight or has errors is found, the suture is difficult to be reversely drawn and the suture is sewn again, so that the local stress of the sewing part is too large to cause secondary injury, the operation is carried out by doctors with abundant experience, and the operation difficulty is increased.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an one-way barb exempts from stylolite of knoing, its aim at overcome current barb stylolite when the operation is sewed up in case the needle insertion tension or needle insertion error, be difficult to the shortcoming of returning.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a suture line of knoing is exempted from to one-way barb, is including the line body that has two ends, the suture needle is connected to an end of the line body, and another end sets up a line and keeps off, the line body only sets up at least one unidirectional umbrella-shaped barb near the end that is close to the suture needle, the umbrella point orientation suture needle of barb.
The line body, barb, line keep off and do not restrict the material kind, can be absorbable or non-absorbable material, and the material can be the same or different.
The thread may be made by a variety of existing spinning techniques, and may be natural or dyed.
The wire stopper is an anti-drop structure and can be a separation blade or a wire ring.
Preferably, the line body is the same with the material of barb, barb and line body structure as an organic whole, the barb can be formed through the direct cutting of cutting device online body surface layer. The barb and the thread body can be made of absorbable Polydioxanone (PDO), the PDO has excellent mechanical strength, and the suture time of the wound supporting part can reach 6 weeks.
Furthermore, the line body, barb, line keep off the material homogeneous phase the same, the line body can be as an organic whole structure with the line fender, through hot melt or hot extrusion or knot formation. The material of the wire body, the agnail and the wire baffle can be poly-p-dioxanone (PDO).
The line body can be coated with different colors at the barbed part for marking.
The utility model has the advantages that: the line body interlude does not have the barb, walks the line easily, does not worry that the situation of acting as go-between tension or making mistakes appears, only strains the suture when getting into the barb position, makes the barb exert oneself through backstitch or side seam, and fixed suture plays the effect of exempting from to tie a knot. The common fishbone barb is not easy to fix, and the umbrella-shaped barb does not slide or deflect relatively between the suture and the wound tissue due to the stress on the periphery, so that the fixation is firm. The surgical suture line is simple in structure, reasonable in design, convenient to use and capable of saving surgical time. The barb part on the line body is coated with color, which is beneficial to the visual identification.
