Description

Suture needle and thread for operation

Technical Field

The utility model relates to the field of medical equipment, in particular to surgical suture needle and line.

Background

In order to make the tail part of the surgical suture needle press the suture line, the suture line is wrapped, so the diameter of the surgical suture needle is far larger than that of the suture line, but the suture line cannot completely block the needle hole due to the structure, and the blood seeps from the needle hole.

The existing annular hollow suture line has the defects that the knot part is not easy to loosen but is limited by the hollow structure, and the suture line is easy to deform and cannot block the needle hole under the tension when being sutured.

In view of the above problems, the present invention provides a surgical suture needle and thread.

Further, the thickness of the transition section is smaller than that of the sewing section and the needle tail of the sewing needle; the width of the transition section is smaller than the width of the sewing section and the needle tail of the sewing needle.

The beneficial effects of the utility model reside in that:

this application adopts the changeover portion that adds the thick gradually to connect suture needle and stylolite, has both guaranteed the connection of suture needle and stylolite, has also guaranteed simultaneously that the overall dimension of stylolite is unanimous with the afterbody of suture needle for the needle eye is stopped up by the stylolite, is difficult for taking place the oozing blood condition.

The interior of the suture is of a solid structure, the upper side and the lower side of the cross section of the suture are parallel, the suture is not easy to deform and distort in the suturing process, and meanwhile, the suture is of a flat structure, so that the contact area of the suture and a sutured tissue structure is large in the tensioning process, the pressure is reduced, the tissue cutting is reduced, and a sutured needle hole cannot be enlarged; the flat design also makes the knot of the suture less likely to loosen.

The left side and the right side of the section of the suture line adopt circular arc design, thereby reducing the cutting force between the suture line and the sutured tissue structure and leading the tissue not to be easily cut.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, a suture needle 1 for operation comprises a suture needle 1 and a suture thread 2 for matching; the tail of the suture needle 1 is connected with a suture 2.

As shown in fig. 1 and 3, the suture needle 1 is flat, i.e. the width of the suture needle 1 is larger than the thickness thereof; in the cross section of the sewing needle 1, the upper side and the lower side of the cross section are parallel straight lines, the stress area is increased, and the left side and the right side of the cross section are arc-shaped, so that the cutting force of the sewing needle 1 and a sewing part is reduced.

The needle point of the suture needle 1 is changed from thin to thick, and the needle body and the needle tail are as wide as and as thick as the suture section 4 of the suture thread 2.

The thickness of the suture needle 1 is between 0.085mm and 0.375mm, and the width thereof is between 0.255mm and 1.125 mm.

The thickness of the needle tail of the sewing needle 1 is between 0.085mm and 0.375mm, and the width thereof is between 0.255mm and 1.125 mm.

As shown in FIG. 1, the needle 1 is an 1/2 circular arc needle with a chord length of 13mm to 44 mm.

As shown in figures 1 and 2, the suture 2 comprises a transition section 3 and a suture section 4 which are connected, wherein the head of the transition section 3 is connected with the tail of the suture needle 1, and the tail of the transition section 3 is connected with the head of the suture section 4.

As shown in fig. 4, the suture section 4 of the suture thread 2 is also flat, i.e. the width of the suture thread 2 is larger than the thickness thereof, so that the suture thread 2 is not easy to deform or distort during the suture process; in the section of the suture line 2, the upper side and the lower side of the section are parallel straight lines, so that the stress area is increased, the pressure is reduced, the tissue cutting is reduced, the sutured needle hole cannot be enlarged, and the left side and the right side of the section are arc-shaped, so that the cutting force between the suture line 2 and a sutured part is reduced, and the sutured tissue is not easy to be cut. The flat design also makes the knots of suture 2 less likely to loosen.

The sectional shape of the sewing section 4 is the same as that of the tail end of the sewing needle 1, and the width and the thickness of the sewing section 4 are the same as those of the tail end of the sewing needle 1, so that the sewing thread 2 can completely block the needle hole caused by the sewing needle 1 through the arrangement.

The sewing section 4 has a thickness of 0.085mm to 0.375mm and a width of 0.255mm to 1.125 mm.

As shown in fig. 1, the length of the transition section 3 of the suture 2 is between 5mm and 15mm, and the length of the transition section 3 is preferably 10 mm; the thickness of the transition section 3 is less than that of the sewing section 4 and the needle tail of the sewing needle 1; the width of the transition section 3 is smaller than the width of the suture section 4 and the needle tail of the suture needle 1.

The transition section 3 of the suture 2 is gradually thickened from the needle tail end to the suture section 4 end. The gradually thickened transition section 3 is connected with the suture needle 1 and the suture thread 2, so that the connection between the suture needle 1 and the suture thread 2 is ensured, and meanwhile, the shape and the size of the suture thread 2 are consistent with the tail part of the suture needle 1, so that the needle eye is blocked by the suture thread 2, and the condition of blood seepage is not easy to occur.

Above is the utility model discloses preferred embodiment the utility model discloses make a plurality of other simple replacements and changes under the design prerequisite, all should regard as belonging to the utility model discloses a protection category.
