摘要:
A surgical system or assembly for performing cardiac surgery includes a surgical instrument; a servo-mechanical system engaged to the surgical instrument for operating the surgical instrument; and an attachment assembly for removing at least one degree of movement from a moving surgical cardiac worksite to produce a resultant surgical cardiac worksite. The surgical system or assembly also includes a motion tracking system for gathering movement information on a resultant surgical cardiac worksite. A control computer is engaged to the attachment assembly and to the motion tracking system and to the servo-mechanical system for controlling movement of the attachment assembly and for feeding gathered information to the servo-mechanical system for moving the surgical instrument in unison with the resultant surgical cardiac worksite such that a relative position of the moving surgical instrument with respect to the resultant surgical cardiac worksite is generally constant. A video monitor is coupled to the control computer; and an input system is coupled to the servo-mechanical system and to the control computer for providing a movement of the surgical instrument. The video monitor displays movement of the surgical instrument while the resultant surgical cardiac worksite appears substantially stationary, and while a relative position of the surgical instrument moving in unison with the resultant surgical cardiac worksite, as a result from the movement information gathered by the motion tracking system, remains generally constant. A method of performing cardiac surgery without cardioplegia comprising removing at least one degree of movement freedom from a moving surgical cardiac worksite to produce at least a partially stationary surgical cardiac worksite while allowing a residual heart section, generally separate from the at least partially stationary surgical cardiac worksite, to move as a residual moving heart part. Cardiac surgery is performed on the at least partially stationary cardiac worksite with a surgical instrument such as needle drivers, forceps, blades and scissors.
