A device for connecting tendons, made in the form of a hollow sleeve with a longitudinal slit and installed in the cavity of the coupling of tissue retainers oriented toward its center.

The disadvantage of this device is increased invasiveness due to the need for surgery in two stages.

The aim of the invention is to reduce the morbidity of the operation by conducting operations in a single step.

The aim is achieved in that the coupling is made with a longitudinal slit, provided shipovym connector, with tissue retainers, chipaway RA is e device.

Device for connecting tendons consists of a clutch made from allograft consisting of two longitudinal parts 1 and 2 together using finger connector 3, for example, type dovetail. The sleeve has a longitudinal slit 4. In parts 1 and 2 clutch installed spikes (tissue retainers) 5 and 6, with the inclination to the center of the clutch. Parts 1 and 2 clutches, fabric clamps 5 and 6 and chipaway connector 3 is made of absorbable allograft.

The proposed device for connecting tendons are used as follows.

Prepare the surgical wound is one of the known methods. One of the tendon ends is placed on the studs 5 of part 1 of the coupling. Then tighten the second tendon end so that he was connected with the first tendon end as closely as possible, and stick it on a spike 5 of part 1 of the coupling. The second part 2 of the coupling unite with the help of finger connection 3 with the first part 1 of the coupling. The studs 6 finally fix the ends of the tendons around the inner perimeter of the coupling. The imposition of the coupling on the tendon carried out so that the tendon mesentery, if it survived at the time of the injury, out of the clutch through a longitudinal slot 4. Then wound the ears of the Tata, for example of a tubular bone, one of the known methods.
