Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to traumatology and orthopedics. After performing refreshing of meniscus fractures under the control of arthroscopy, a back port is formed, in which a protective cannula is placed. Through the front port from inside to outside under the control of arthroscopy through the posterior horn of the meniscus there is a curved needle, and its point is visualized behind a meniscus horn. Monofilament suture is introduced through the needle lumen and withdrawn by a clamp from a joint cavity through the back port into a protective cannula. At end of monofilament thread in front port there formed is knot, in which braided thread is fixed. Braided thread is inserted into the joint by the monofilament suture by pulling through the meniscus into the protective cannula. Using the clamp, the free end of the braided suture is transferred above the posterior horn of the meniscus into the posterior parts of the joint. Free end of the braided thread over the meniscus is brought out to the back port by means of a clamp. In rear port cannula, therefore, two free ends of braided thread after its through posterior horn of meniscus. On one end of the thread a sliding assembly is applied and, by traction after the other end, the threads are fixed on the meniscus. Seam by two subsequent nodes is blocked by means of a sniffer of the assembly. Ends of threads above knot are cut in joint cavity through installed cannula by means of nippers. Actions are repeated in the same way along the whole length of the meniscus hinge rupture by controlling the meniscus reduction by arthroscopy. Skin is sutured. 
     EFFECT: method improves reliability of fixation of a damaged posterior horn of a meniscus due to application of a stable suture without involvement of a capsule, and also simplifies suture execution due to possibility of threads in all required directions under visual control.

Abstract: FIELD: oil and gas industry.  
     SUBSTANCE: device for catching and holding the broken end of the cable at the mouth from going into the well belongs to the oil and gas industry, namely to the field of research and development of wells using a geophysical cable or other flexible traction element. The device includes a hollow body with an axial opening, which has a length sufficient for the installation of three clamps in it, forming locking assemblies at three levels, working in parallel, but independently of each other. End stops made with a larger outer diameter than that of the body form two annular bands for fixing between them a pipe elevator holding the device at the wellhead. For working with wire, the body is made with an inner conical surface, and the clamps are made in form of three balls of different diameters. To work with the cable, a cylinder with an inner conical surface, made up of two halves, is installed in the housing, and the clamps are made in form of three balls of different diameters. The body and end stops have a lateral longitudinal slot. The axial hole of the upper end stop is oval to keep the clamps from falling out, while maintaining possibility of fully pressing the cable to the tapered surface, along the line of the major axis of the oval. When working with a traction belt, a cylinder with a wedge-shaped channel, made up of two halves, is installed in the body. The axial hole is rectangular in cross-section that corresponds to the tape passed through it. The clamps are made in form of three balls of different diameters or rollers from roller bearings, the body and end stops have a lateral longitudinal slot. To keep the clamps from falling out, a truncated disc is installed between the upper stop and the composite cylinder, on which the wedge-shaped channel is made.  
     EFFECT: increasing reliability of work by keeping the upper end of the emergency-cut flexible traction element at the wellhead from going into the well.

Abstract: FIELD: information processing. 
     SUBSTANCE: invention relates to the field of processing and transmission of discrete information. To realise the described effect, a method for transmitting multiblock messages by cascade code is proposed, consisting in the fact that the source information on the transmitting side is divided into blocks of a predetermined length, used to form a message. A message is comprised of a title used to determine the sequence number of the blocks, an information or verification block, and a verification stage. Sets of verification blocks are then formed for sets of these blocks. A synchronising sequence is added to each block encoded by a cascade code, and the obtained combination of characters is transmitted to the receiving side. Synchronisation is performed not only by error-free code words, but also by code words containing errors. Decoding is performed simultaneously for hard and soft solutions, and multiple attempts are made in decoding the matrices of the multiblock message. Low-level matrices are used in encoding. After the blocks are decoded, the original messages are collected and transmitted to the recipient. 
     EFFECT: increasing the reliability of transmission of multiblock messages and reducing the time of transmission thereof.
