METHOD FOR DETECTING TRANSPLANT'S LENGTH DURING RESTORATIVE MICROSURGICAL OPERATIONS UPON NERVES, BLOOD VESSELS AND TENDINOUS-MUSCULAR COMPLEX Russian patent published in 2004 - IPC

FIELD: medicine, surgery.

SUBSTANCE: one should measure tension powers in distal and proximal ends of the structure under restoration, area of cross-sectional section in restorative and transplanted structures, one should detect tension power of restorative structure when its is stretched for 1 cm, it is necessary to detect the value of this power referred to area unit of cross-sectional section of restorative structure; one should measure longitudinal tension power of transplanted structure and detect its ratio to area unit of cross-sectional section of transplanted structure. One should detect transplant's length l_req due to the following ratio: where d - diastasis value; F_s - longitudinal tension power of transplanted structure referred to area unit of cross-sectional section of this structure; F_cs - tension power referred to area of cross-sectional section of restorative structure; Moreover the quotient has got dimensionality of length units matched for measuring. The method provides possibility to detect optimal transplant's length.

EFFECT: higher accuracy of detection.
