Embodiment Construction

[0145] figure 1 A portion of an instrument set of a robotic surgical system according to an embodiment of the present invention is shown in a perspective sectional view.

[0146] The instrument set includes an instrument 1 , a drive unit 2 connected to the instrument 1 , and an instrument interface arranged between the drive unit and the instrument, and the instrument interface has a sterile shield 5 .

[0147] In this embodiment, the axis of rotation of the drive unit coincides with the shaft axis of the instrument. This concept is especially suitable for instruments activated via a pull / push rod.

[0148] exist figure 1 The left side of the diagram shows a sterile surgical instrument 1, in figure 1 The drive unit 2 is shown on the right in . The instrument 1 is mechanically detachably connected to the housing 6 of the drive unit 2 via a connecting flange 4 at the proximal end of the instrument shaft 3 . The drive unit 2 is surrounded by a sterile shroud 5 to prevent con...

Abstract

A robotic surgery system includes a robot and an instrument assembly. The instrument assembly includes a drive unit with at least one rotary drive having an electric motor and a drive shaft that has a coupling part for coupling to a drive shaft of the instrument; an instrument including an instrument shaft and a drive shaft that has a coupling part for coupling to a drive shaft of the drive unit; and an instrument interface including a sheath that encompasses the drive unit. In order to detachably couple an instrument module to an instrument part of a surgical instrument, an electromagnet in a magnet assembly of the instrument module is activated or deactivated, a permanent magnet of said magnet assembly is moved into a locking position and / or an angular position of a coupled counter element assembly of the instrument part is detected by an angle sensor of the instrument module.
