FIELD: medicine.
SUBSTANCE: retention anchor for fixation of suture material relative to solid tissue comprises pin part. On the periphery of the pin part there is a material having thermoplastic properties, and for retention of the suture material, a suture passage at the distal end of the pin part. To fix the suture material relative to solid tissue, the distal suture can be deformed by a compressive load. Method of securing suture material in solid tissue using a suture retainer involves steps: taking a suture anchor containing a pin portion, wherein on periphery of pin part material with thermoplastic properties is arranged, and a suture passage at a distal end of the pin portion, wherein to fix the suture material relative to the retainer, the distal suture can be deformed. Orifice is made in a hard cloth having such cross-section size that force is required to install the pin part into the above hole in the hard tissue. Forcefully inserting the piercer portion of the suture retainer into the hole in the hard tissue, transferring the vibratory energy to the anchor retainer for a time sufficient for diluting the material, having thermoplastic properties in places of contact with solid tissue inside hole in solid fabric. Suture material is fixed by means of its clamping between a hard tissue and a site on a proximal end of a pin part or by means of its clamping by deformation of a seam passage. Set for fixation of the suture material relative to a solid tissue contains the above-mentioned retention retainer and a vibration instrument. Vibration tool is configured to fix the retention latch in the solid tissue opening by placing the distal end of the instrument opposite to the proximal end of the retainer and transmitting the pusher force and mechanical vibrations from the vibration tool to the seam fixture. Proximal end of the fixator has an inlet section of the retention groove passing in the axial direction along the peripheral surface of the retention retainer. Distal end of the instrument and the proximal end of the retainer are so adapted to each other that the distal end of the instrument does not close said inlet section, available on the proximal end of the retainer, when the distal end of the instrument is located opposite to the proximal end of the retainer for fixation.
EFFECT: suture retainer, a method and a kit for anchoring a suture material relative to a solid tissue are disclosed.
