Problems solved by technology

At the same time, the spring properties do not allow the use of the material when it is placed in thin anatomical structures (such as the submucosa of the eyelid, the cornea, etc.), due to the possibility of tearing the material or placing it on the mucosa with a single thread of titanium mesh. risk of punching
Currently available materials cannot quickly and properly place natural metal tricots in thin anatomical structures with mucous membranes and adjacent tissue thickness less than 1mm, nor can they fix their entire surface uniformly to the tissues of surgical wounds

Embodiment 1

[0045] Endoprostheses for keratoplasty made of tension-free metal tricot with a wire diameter of 30 μm and a size of 3x3x mm were obtained for three experimental animals (rabbits, 4 months old) and implanted using standard surgical techniques. enter. During the implantation procedure, a high plasticity of the material is noted, which makes it easy to place the material in the corneal tissue. Simultaneously, an upper eyelid rupture with a connective tissue defect was simulated, filled with the same metal tricot. The main purpose is postoperative wound healing. After 10 days, the animals were withdrawn from the experiment. When the morphological changes were studied, white scars were found over the entire surface of the reticular fabric; microscopically, the structure of the postoperative scar appeared as ordered connective tissue fibers without signs of sterile inflammation.

Embodiment 2

[0047] Surgical intervention implanted the claimed tension-free titanium metal tricot in rats generally anesthetized by intraperitoneal injection of 30 mg / kg sodium pentobarbital (Nembutal). At the time of the intervention, the animals were 6 months old.

[0048] Create a surgical wound on the anterior abdominal wall of the experimental animal by dissecting the skin, muscle, and subcutaneous fat tissue into the peritoneum. The tension-free titanium metal warp braid retroperitoneum was implanted at the border between the metal warp braid and the peritoneum, and its thickness did not exceed 0.5 mm. Apply muscle sutures, subcutaneous fat sutures, and skin sutures. All animals were divided into two groups, 6 animals in each group.

[0049] In the first group (control group), meshes made of natural metal tricot with non-contour lines were used for implantation. In the second group, individuals were implanted with a tension-free titanium metal warp braid having a contour with a v...

Abstract

The invention relates to the fields of medicine and medical technology, and is directed toward improving the technical properties of mesh implants used for delicately surgically shaping thin anatomical structures: eyelids, cornea, etc. A tension-free titanium metal warp knit fabric for surgically shaping soft tissues is a mesh fabric made of titanium threads bent to form interconnected loops, wherein the titanium threads have a contoured surface. The technical result is a decrease in the elasticity and an increase in the plasticity of the material, making it possible to incorporate said material into thin anatomical structures without risk of trauma, while improving the formation of connective tissue, reducing wound discharge, shortening healing times, and reducing the rate of complications, thus enabling more rapid recovery of patients.

Description

technical field [0001] The present invention relates to the field of medicine and medical technology, and aims to improve the technical performance of mesh endoprostheses for fine surgical shaping of thin anatomical structures: eyelids, facial tissue, inguinal ring, etc. Background technique [0002] Such a solution is known from the prior art (RU 160627 U1, published on March 27, 2016), which describes a mesh material for hernia repair. The titanium mesh with the bioactive coating is secured peripherally to the edge with interrupted U-shaped sutures or continuous sutures. A second peripheral suture can be used along the edge of the hernia hole if very secure fixation of the mesh to the tissue is desired. [0003] A disadvantage of this solution (ie the one described above) is the use of additional fixators when fixing the mesh endoprosthesis in the form of sutures or staples made in various ways. This solution cannot quickly establish a firm fixation of the endoprosthesis...
