FIELD: medicine. ^ SUBSTANCE: invention refers to medical engineering and can be used for the formation of anastomoses at surgical treatment of gastrointestinal tract diseases. Device for overlapping a circular anastomosis comprises a body, bracket mechanism with guide grooves, pushers, a cassette with straps and tape with holes for knee braces. The body is made in the form of L-shaped frame. The frame consists of two mechanically bonded halves in the inner space of which there is a compressing lever, fuse, support shaft and compressing rod spring-mounted at the two ends. The rod has an option of turning around the axis which is fixed on the L-shaped frame and is located closer to the distal end. The proximal portion of compressing rod has a longitudinal groove. Inside the groove with an option to move the compressing lever end is fixed having a spinning axis fixed to L-shaped frame and an option to rest upon the fuse. The support shaft is made detachable and is able to interact with the support embodied in the L-shaped frame and with a screw. The screw is installed in the middle part with an option of rotation inside of the L-shaped frame. The distal parts of the L-shaped frame, compressing rod and supporting rod are designed in the form of non-closed rings. Outer diametre of L-shaped frame non-closed ring is larger than the outer diametre of non-closed ring of compressing rod and is equal to the supporting rod outside diametre. The non-closed rings internal diametres of L-shaped frame and the supporting rod are made equal and designed equal to the outer diametres of cassette with straps and holes for knee braces. ^ EFFECT: free carrying of saturated intestine parts in order to fix them on acuses of sterilising matrices. ^ 3 cl, 4 dwg |
