Abstract

An anti-twining double-ended needle suture line with a directionless pad consists of needles, a suture line and the pad threaded with the suture line. The suture line penetrates through the pad along a long-axis direction of the pad, so that the suture line and the pad are coaxial. After the front stitch is finished, the suture line of the other needle is straightened to suture, the pad can not be limited by directions, and the suture line is not easy to be twined, and can be knotted without special straightening operation of operators.

Description

With the anti-double needle suture that twines of directionless pad

Affiliated technical field:

This utility model relates to a kind of band pad suture of operation on heart, is particularly useful for the stitching in artificial cardiac valve prosthesis's displacement and the various cardiac operation.

Background technology:

At present, the artificial cardiac valve prosthesis replaces stitching thread and is made up of the suture and the pad of band double needle, suture passes at proximal edge place, pad two ends perpendicular to pad, make double needle pass valvular lobe ring and artificial valve's woven dacron respectively when sewing up the artificial valve, and carry out the double end line self the knotting, thereby fixing artificial valve, the pad role is to avoid suture cutting and stitching tissue, causes and tears.But, in clinical use, find, because suture passes perpendicular to pad, two strands are closely parallel, and the line body is zero to the lateral control force of pad, the double end line easily twines, and suture passes pad directivity, and pad is easy to upset, and operator often needs specially to correct the pad direction and twines suture, otherwise may cause knotting not fastening, the artificial valve is loosening.This has greatly disperseed the operator attention, has prolonged operating time, particularly operates in narrow and small, the darker heart in space, and the operation of correcting pad and suture is wasted time and energy, and increases operation risk greatly.

Summary of the invention:

Easily overturn in order to overcome pad, the double end line easily twines, and operator need specially be corrected pad direction and the deficiency of twining suture, it is a kind of with the anti-double needle suture that twines of pad that this utility model provides, this suture pad is non-directional, and the line body is difficult for twining during stitching, and operator need not specially to correct.Greatly make things convenient for operation technique, saved operating time.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of with the anti-double needle suture that twines of directionless pad, form by the pad that suture needle, line body and line body run through.The line body is run through along the pad long axis direction, and entry and exit point is positioned at 1/2 place of spacer thickness.Keep pad two side line body lengths identical.Because suture and pad are on same axis, otherwise pad does not have just branch.After a seam was finished, the other end only needed get final product the line body is stretching, and nothing notes the pad direction.Simultaneously, because the line body is added the directionless branch of pad to the lateral control force of pad, double end line body twines problem and has not also existed.

The beneficial effects of the utility model are, when operator utilizes this suturing with thread management, need not specially to correct the pad direction and twine suture, have made things convenient for operation technique, have saved operating time.

Description of drawings:

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is existing band pad double needle suture structural map.

Fig. 2 is this utility model structural map.

Fig. 3 is the schematic diagram of existing band pad double needle suture implementation and operation.

Fig. 4 is the schematic diagram that this utility model is implemented.

1. pads among the figure, 2. suture body, 3. suture needle, 4. artificial valve's suture ring

A. have pads placement correct when being with pad double needle suture to sew up now

B. existing band pad double needle suture the line body occurs when sewing up and twines

The pad upset appears in c. existing band pad double needle suture when sewing up

Operating process when d., e. this utility model is sewed up

The specific embodiment:

In Fig. 1, present band pad (1) double needle (3) suture line body (2) runs through pad in vertical direction, in use notes the pad direction; And the line body twines (b) and pad upset (c) easily, has only pad (a) in the right direction just can make line body knotting firmly (Fig. 3).This utility model suture runs through pad (Fig. 2) along the pad major axis, has changed the direction relations of suture body and pad, by vertically changing on same axis, has strengthened the control force of line body to pad; On the other hand, otherwise because the pad after changing does not have just branch, so nothing notes the pad direction.

In the embodiment shown in fig. 4, after the stitching of first pin finishes, only need and will sew up behind another suture needle line body stretching (d), the pad of forgetting it can be tied a knot.

Claims

1. the double needle suture with the anti-winding of directionless pad is made up of the pad that suture needle, line body and line body run through; It is characterized in that: suture line body runs through pad along the pad long axis direction, and line body and pad are on the same axis, and pad does not have positive and negative difference.
