an elongated body,

and at least of one drive member designed for transmitting a driving motion from said power unit to said surgical assembly and movably disposed within said elongated body,

a distal coupling means for coupling the distal ends of said drive assembly to said surgical assembly,

a separable proximal coupling means for detachable coupling the proximal ends of said drive assembly to said power unit,

an operating means designed for an operation control of said surgical assembly and disposed on said drive assembly distally of said separable proximal coupling means.

2. The surgical apparatus of claim 1, wherein said distal coupling means is separable allowing detachable coupling the distal end of said drive assembly to said surgical assembly, and said distal and proximal coupling means have identical design allowing the use of any end of said drive assembly for coupling to said power unit and correspondently to said surgical assembly.

3. The surgical apparatus of claim 1, wherein said operating means has a stiffening means including a rigid element participating in the transmission of surgeon controlling efforts directed to said surgical assembly.

4. The surgical apparatus of claim 3, wherein said rigid element is made as a rigid portion of said drive assembly.

5. The surgical apparatus of claim 1, wherein said operating means is detachably set on said drive assembly by means of a mounting means.

6. The surgical apparatus of claim 5, wherein said mounting means includes a resilient member like a rubber spacer compressed between a clamping nut and a base of said operating means and forced out in the direction of said drive assembly thereby fixing said base on said drive assembly.

7. The surgical apparatus of claims 3, wherein said stiffening means is made as a supporting means having said rigid element detachably set on said flexible portion of drive assembly to impart a rigidity to said flexible portion of drive assembly during the surgical apparatus operation and there is a mounting means for said detachably seting.

8. The surgical apparatus of claim 1, wherein said operating means is provided with a holding means including a handle designed for holding the surgical apparatus by surgeon during the execution of the surgical operations.

9. The surgical apparatus of claim 8, wherein said operating means includes an operation desk disposed on said holding means and designed for the surgeon control of the surgical assembly motions including at least the control of said power unit.

10. The surgical apparatus of claim 1, wherein a distal end portion of said drive assembly is flexible and there is at least one steering wire disposed within said drive assembly along its axis and connecting said flexible distal end portion of drive assembly with a steering member disposed distally of said proximal separable coupling means and designed for turning said surgical assembly by surgeon, there is a holding means including a handle designed for holding the surgical apparatus by surgeon during the execution of the surgical operations and said steering member is disposed on said holding means.

11. The surgical apparatus of claim 1, wherein said power unit includes an least one electric motor, said drive member is flexible, axially rotatable and capable of transmitting a torque from said electric motor into said surgical assembly, where the rotation motion of said drive member is transformed into another needed motion kinds.

12. The surgical apparatus of claim 11, wherein there are at least two said rotatable flexible drive members.

13. The surgical apparatus of claim 1, wherein said drive member is capable of transmitting a pulling/pushing effort from said power unit into said surgical assembly.

14. A surgical apparatus, having

a surgical assembly,

a power unit providing the needed power for actuating said surgical assembly,

a drive assembly connecting said power unit and said surgical assembly, being flexible at least in the limits of the part of its length, and including

an elongated body,

and at least of one drive member designed for transmitting a driving motion from said power unit to said surgical assembly and movably disposed within said elongated body,
