摘要：
FIELD: medicine.SUBSTANCE: group of inventions refers to versions of a surgical instrument (CI) and a connecting structure for attaching its end effector (EE). The CI contains EE, a proximal rotary transfer assembly (RTA), a distal RTA, a proximal axial transfer assembly (ATA), a distal ATA, and a connecting structure for simultaneous attachment of the proximal RTA to the distal RTA and the proximal ATA to the distal ATA and their simultaneous disconnection. The proximal RTA is functionally connected to a source of rotary and axial control movements. The proximal RTA is additionally configured to be displaced longitudinally as a result of communicating to it the axial control movements. The distal RTA is functionally connected to the EE to communicate to it the rotary control movements. The proximal ATA is functionally connected to a source of other axial control movements. The distal ATA is functionally connected to the EE to communicate to it the axial control movements. A connecting structure for attaching a EE including a plurality of distal transfer assemblies configured to communicate a plurality of control movements of the EE corresponding to proximal transfer assemblies connected to a driving motions source, wherein the structure comprises a proximal fixing structure (PFS) at the distal end of each proximal transfer assembly, a distal fixing structure (DFS) at the proximal end of each distal transfer assembly, a proximal connecting element (PCE), a distal connecting element (DCE) and the blocking ring (BR). The PCE is configured with the ability of functional support of each proximal transfer assembly so that the PFS is held in the aligned position for the connection. Each DFS is configured with the ability to engage functionally the PFS at the distal end of the corresponding proximal transfer assembly when they are engaged in interlocking with each other. The DCE is functionally connected to the EE and is configured with the ability to functionally support
