Description

Special device is sewed up to uterus braces formula

Technical Field

The utility model relates to the technical field of medical equipment, specifically relate to a special device is sewed up to uterus braces formula.

Background

In the delivery process of obstetrics and gynecology department, 5-8% of cases of relaxant hemorrhage caused by major hemorrhage due to uterine muscle contraction and weakness after delivery of the fetus are confirmed. There are also conditions in which the placenta covers the uterine orifice, resulting in a pre-placenta that is not capable of vaginal delivery and requires caesarean section. Especially the pre-placenta of the inland danger type is the most dangerous disease condition in the process of delivery. These conditions are most often effective with compression hemostasis. The operation of hemostasis by compression is carried out by inserting suture needle into the position of 2-3cm lower edge of 3cm position at both sides of uterus incision, penetrating through uterus back wall at the same horizontal line position via uterine cavity, and passing out. The suture thread is tightly adhered to the front and back walls of the uterus and knotted at the bottom of the uterus. However, the existing needle for suturing without a uterus braces type has the defects that the knotting is easy to loosen and slip due to the extremely high tension when knotting, so that the operation is inconvenient and the operation difficulty is increased. Meanwhile, the compression is not thorough, so that the condition of secondary bleeding is easy to occur, and the clinical use of the traditional Chinese medicine is limited. The existing agnail suture line is of a curved needle structure, is short in length, cannot penetrate out of the uterus from the needle entering position through the uterine cavity at the same horizontal line position, and brings hidden troubles to operation safety.

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, the utility model provides a special device 100 is sewed up to uterus braces formula, including sewing needle 1 and stylolite 2, sewing needle 1 is straight needle, and then make sewing needle 1 run through straightly, furthest shortens sewing needle 1, stylolite 2 walks at the inside capable of walking of uterus 9, reduce the damage to uterus 9 itself in the art, and simultaneously, use straight sewing needle, it is clear and definite to go out the needle position, the operation doctor can sew up the position that wants the sewing up reliably, and can reduce the danger of the blood vessel of accidentally injuring near uterus 9 tissue or peripheral visceral organ in the art extremely low, sewing needle 1's one end is connected with stylolite 2's one end, be equipped with a plurality of barbs 8 on stylolite 2, barb 8 can effectively prevent to tighten the time slide wire when tying, guarantee that the firm of ligature is firm, shorten the time of hemostasis in-process, can provide great tension for hemostasis by compression simultaneously, thereby improve hemostatic effect, make uterus 9's palace bottom hemostasis operation safer, convenient, go on going on easily, barb 8 sets up towards one side of keeping away from sewing needle 1, and then avoid the barb 8 influence the suture process of sewing needle of sewing.

Specifically, the suture needle 1 comprises a needle point 3, a needle body 4 and a needle tail 5 which are fixed into a whole in sequence, wherein the needle point 3 is a cone so as to facilitate needle insertion, one end of the needle point 3 is in smooth transition with one end of the needle body 4, the needle body 4 and the needle tail 5 are cylinders with the same outer diameter, and one end, far away from the needle body 4, of the needle tail 5 is used for connecting a suture thread 2. The outer surface of the suture needle 1 can be provided with a coating according to actual needs.

The outer diameters of the needle body 4 and the needle tail 5 are smaller than 1.5mm, the length of the suture needle 1 is 40mm-80mm, and the length of the suture needle 1 is longer, so that the suture process can be completed at one time, and the time loss and the uterus 9 injury caused by multiple times of suture in the suture process are avoided.

The suture needle 1 is made of stainless steel, such as 317L, 420, 3Cr13, 304 and other high-quality stainless steel, and can be bent for many times.

Suture 2 includes linkage segment 6 and barb section 7, and the one end of linkage segment 6 is fixed with the one end of sewing needle 1, and the external diameter of linkage segment 6 equals or slightly is less than the external diameter of backshank 5, makes to sew up more smoothly to reduce uterus 9 damage, the other end of linkage segment 6 is fixed as an organic whole with the one end of barb section 7, preferably integrated into one piece, and linkage segment 6 and 7 external diameters of barb section equal, and barb 8 integrated into one piece is on the outer wall of barb section 7. Preferably, the barbs 8 may be arranged randomly, in a spiral arrangement or symmetrically about a circular point of the cross-section of the barb segment 7, the barbs 8 forming an outermost turn of the tape having a diameter greater than the diameter of the needle 1.

The length of the connecting section 6 is 5mm-50mm, the diameter is 0.35mm-0.4mm, the diameter is larger, the cutting of the suture 2 to the uterus 9 during knotting can be reduced, and the damage to the uterus 9 is reduced. The length of the barbed section 7 is not less than 500mm. The suture 2 is longer, which can ensure to be applicable to the majority of patients to finish the suture hemostasis process once. The material of the suture thread 2 can be degradable material or non-degradable material according to actual need, which can reduce the cost of the special uterine sling type suture device 100, thereby reducing the economic burden of patients. Wherein, the degradable material can be selected from polydioxanone, polylactide, polyglycolic acid polylactide, polycaprolactone and copolymers thereof, etc.; the non-degradable material can be selected from polypropylene, polyurethane or polyester.

The suture 2 and the suture needle 1 are fixed by parallel extrusion or riveting.

As shown in FIG. 2, in actual use, a needle holder is first used to hold the back 1/3 of the needle 1 on one side of the uterus 9, and the angle between the needle holder and the needle 1 is preferably 90 °. The needle tip 3 penetrates the anterior and posterior walls of the uterus 9 in sequence from the needle insertion point c1, exits from the needle exit point c2, is then tightened over the uterus 9 with the barbed section 7 of the suture 2, and is tied off at point a. On the other side of uterus 9, using the same method, the needle holder holds suture needle 1, and needle tip 3 penetrates the anterior wall and posterior wall of uterus 96 from needle insertion point d1, and then penetrates needle exit point d2, and then is tightened with barbed section 7 over uterus 9, and knotted at point b. The barbs 8 on the surfaces of the barb sections 7 can effectively prevent the slide line from being tightened and knotted, so that the compression hemostasis is formed at the bottom of the uterus 9.

The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for those skilled in the art, the idea of the present invention may be changed in the specific embodiments and the application range.
