Definitions
- the invention relates to the fields of medicine and medical technology and is aimed at improving the technical properties of surgical suture material.
- the prior art surgical suture material in the form of a filament of an alloy based on nickel-titanium (RU 2234868 C2, publ. 27.08.2004).
- the material is made of nickel-titanium, does not have a smooth surface and has the so-called "sawing effect" in relation to tissues, cannot serve as a depot of drugs.
- the phase heterogeneity of titanium nickelide creates the likelihood of diffusion of nickel ions into the surrounding tissue, which can be a source of persistent inflammation.
- the prior art knows the solution closest to the one claimed (RU 1 16035 U1, publ. 05.20.2012).
- Surgical titanium suture material (options)).
- the surgical suture material is made of a titanium alloy, includes a needle tip interconnected with a multifilament suture thread, while the monofilament of the multifilament suture thread intersects at an angle to the longitudinal axis of the suture material.
- the material is made of ordinary multifilament titanium material, does not have a smooth surface and has the so-called “sawing effect” in relation to tissues, cannot serve as a depot of medicines, the risk of suture material breaking is high.
- most polymers have poor adhesion and do not allow self-fixation elements to form on it in the form of spikes, petals, etc. constructions.
- the claimed suture material can significantly overcome these disadvantages inherent in the prototype.
- the technical problem that the proposed technical solution solves is the creation of suture material with high strength, elasticity and plasticity, devoid of a “sawing” effect with respect to tissues, having a low coefficient of sliding friction, and also capable of carrying antibacterial and other medicinal substances in its structure, while the material should be designed for a long stay in the body and in the long-term postoperative period have a high biological inertness, do not initiate or support aseptic inflammation associated with its presence in the body.
- the technical result consists in increasing the strength, elasticity and plasticity of the suture material, the absence of a “sawing” effect in relation to tissues, increasing the coefficient of sliding friction, as well as providing the ability to serve as a depot for antibacterial and other medicinal substances, ensuring a long stay in the body and , in the remote postoperative period, having high biological inertness, excluding the initiation and maintenance of aseptic inflammation associated with found taking material in the body.
- the composite surgical suture material consists of titanium monofilaments assembled into a multifilament thread, while in the spaces between the monofilaments and on their surface a bioresorbable polymeric material is made, and the monofilaments have a relief surface.
- Monofilaments are made of titanium grade GRADE-5.
- the relief surface of the monofilament is made by chemical etching.
- a bioresorbable polymer material is a polymer from the group of polylactic acid, silk fibroin or polyhydroxybutyrate.
- the multifilament yarn is made with a diameter of 0.04 mm to 2 mm.
- the multifilament yarn is made in the form of a tape 0.2-1 mm thick and 3- wide
- the structure of the bioresorbable polymeric material contains at least one drug.
- Self-fixing elements are formed on the surface of the material in the form of spikes having a triangular shape with an acute angle, facing in the direction of movement of the material, and the opposite side of the triangle against movement.
- Self-fixation elements are formed on the surface of the material in the form of petals folded in one direction, having sharp tips directed to the side against the movement of the surgical material.

- Fig. 8 Image of composite surgical suture material with self-fixing elements in the form of spikes formed from a bioresorbable polymer.
- Suture material is intended for use in surgical interventions in various fields of surgery (abdominal, dentistry, orthopedics, including for stitching stitches). It is used for stitching fascial-muscle formations, stitching organs capsules, stitching tendons, for bone grafting, for fixing implants, etc.
- the basis of the invention is the combination of multifilament titanium filament with optimal strength and elasticity for surgery and biologically resorbable polymers, eliminating the sawing effect.
- Composite surgical suture material can consist of 3-96 titanium monofilaments 2, assembled into a multifilament yarn 1 and between which a bioresorbable polymer material is present in the gaps and on their surface 3.
- Such material may be polymers from the group of polylactic acid, silk fibroin, polyhydroxybutyrate, etc.
- the multifilament yarn 1 can be twisted in the form of a cable ( Figure 1), woven in the form of a microtube ( Figure 2), or otherwise connected.
- Suture material can have a diameter of 0.04 mm to 2 mm, and also have the form of a tape with a thickness of 0.2-1 mm and a width of 3-5 mm. (Fig. 3)
- Titanium monofilaments can be made of titanium grades GRADE-1 (VT1.00, VT1.00 sv) or GRADE-5 (VT6) and have a relief surface.
- a multifilament embossed titanium thread is characterized by a decrease in the area of wire contacts of individual monofilaments, which is due to a decrease in their diameter, carried out, for example, by chemical etching already at the stage of formation of a multifilament material (Fig. 46) compared with the starting material (Fig. 4a).
- figures 4A and 46 a section is given of the initial and embossed titanium threads. They show that a decrease in the contact area occurs both due to a decrease in diameter and due to a change in the surface structure, which takes the form of a chaotically built relief. At the same time, upon receipt of the relief, gap spaces appear between the filaments, thus, the multifilament embossed titanium filament has an increased porosity. The result is a reduction in contact length and contact area of used threads.
- the surface relief is a significant factor in improving the fixation of the biologically resorbable polymer to the material, since the surface roughness increases the coefficient of sliding friction. Due to the penetration of the polymer into the gap spaces, the adhesion of the polymer to the titanium filament increases.
- embossed titanium thread The technological processes that make it possible to obtain embossed titanium thread are: chemical etching, electrochemical polishing, etc.
- Such processing which reduces the diameter of the titanium filament by 5-35% of the initial diameter, can significantly reduce the density of weaving of the material and at the same time achieve maximum ductility. Thanks to these processes, a specific surface relief arises on the surface of the material: randomly extending depressions and mounds with a rounded surface.
- Distinctive features of the surgical material is the uneven diameter of the titanium thread (Fig.4b). Fluctuation of the diameter of the filament in a monofilament filament (depending on the initial diameter) is 0.1 -10 microns
- the surface layers are cleaned of the remains of technological lubricant and other impurities, which significantly increases the biological properties of the material.
- the high ductility of the embossed thread minimizes spring properties, reduces the likelihood of a biomechanical conflict between suture material and body tissues and allows the material to be placed in delicate anatomical structures without the risk of injury.
- Composite suture material obtained from embossed titanium thread is freely expanded in the area of the surgical wound, does not form unnecessary loops and easily forms surgical nodes.
- High porosity increases the rate of penetration of biological fluids into the suture material during the biodegradation of the polymer, accelerates its colonization with fibroblasts and osteoblasts, and improves biological integration.
- the surface relief of the thread significantly improves the fixation of fibrin fibers on it, thereby contributing to the attraction of fibroblasts serving as a source of newly formed connective tissue.
- the material can be equipped with one or two atraumatic needle tips.
- composite suture material can be used as a self-fixing material in those clinical situations where it is desirable to avoid knitting surgical knots.
- Composite suture material may contain self-fixing elements, which are petals 4 (Fig.7) with a length of 1 -4 mm and a wound width! -1 the diameter of the suture material, folded in one direction, having sharp tips directed to the side against the movement of the surgical material, or representing spikes 5 (Fig. 8) with a height of 0, 1-2 mm, having a triangular shape with an acute angle, facing in the direction of the movement of the material, and the opposite side of the triangle against the movement, so as to prevent the surgical suture from going through.
- Distance between elements self-fixation along the length can be from 0.5 to 2.5 cm.
- Elements of self-fixation are also made of polymer material.
- polymers can significantly improve the ergonomics of the material, eliminate the “sawing effect” and control biological processes in the surgical wound in the short term, and the biological inertness of titanium allows the postoperative scar to form fully in the long term.
- the polymer structure may contain at least one drug: antibiotics, anti-inflammatory drugs, etc. Gradually released drugs can have a prolonged therapeutic effect, preventing inflammation and the development of wound infections.
- the resulting material has a smooth surface and eliminates the "sawing effect", which compares it favorably with conventional multifilament titanium material, where the creation of a smooth surface is an unattainable task.
- the polymer is resorbed by the cells of the body, and in its place there remains an inert titanium thread that does not harm the body.
- Three laboratory animals (4-month-old rabbits) created a model of a ventral hernia on the outer side of the anterior abdominal wall using a 3x3 cm mesh implant through open surgical access.
- the implant was retroperitoneally installed.
- Subcutaneous fat is sewn with suture material consisting of three monofilament filaments with a diameter of 60 ⁇ m and polylactic acid with self-locking elements in the form of spikes.
- suture material When working with suture material, its good slip in tissues with simultaneous self-fixation (lack of counterflow) was noted.
- Leather is sewn with interrupted seams. Postoperative wound healing by primary intention. After 3 months, the animals were withdrawn from the experiment. When studying morphological changes, it was found: a whitish scar is determined over the entire surface of the mesh implant. In the area of suture application, traces of polylactic acid are not determined; microscopic examination of the structure of the postoperative scar is represented by ordered connective tissue fibers without signs of aseptic inflammation.
- the implantation operations of the composite suture material were performed in rats under conditions of general anesthesia with Nembutal 30 mg / kg intraperitoneally. The animals were 6 months old at the time of intervention.
- An operative wound was formed on the lumbar region of the laboratory animal by dissecting the skin, muscles and subcutaneous fat in the lumbar region.
- the wound was contaminated with a Staphylococcus aureus culture of 109 CFU / ml. All animals were divided into three groups of 6 individuals.
- the second group used the claimed composite suture material, with a filament diameter of 2 mm, containing not only titanium filaments, 35% of the floor hydroxybutyrate and 3% of vancomycin in the third group (three individuals) was used for suturing wounds as claimed composite suture as a ribbon thickness of 0.2 mm and a width of 3 mm, containing, besides the titanium filaments 35% polylactic acid and 5 volume% of tobramycin,
- the claimed composite surgical suture material based on multifilament titanium filament and bioresorbable polymers has increased strength, elasticity and plasticity, ensures the absence of a “sawing” effect in relation to tissues, and is also able to carry antibacterial and other medicinal substances in its structure that prevent the development of infectious inflammation in the wound .
- the claimed suture material In the distant postoperative period, after resorption of the polymer, the claimed suture material has a high biological inertness, precluding the initiation and maintenance of aseptic inflammation associated with the presence of a foreign body in the body.
