Operation Assistance System

Abstract

An operation assistance system includes a base unit 2 and a robot kinematics device connected to the base unit. The robot kinematics device includes a support column 3 as well as at least a first and second robotic arm 4, 5. A lower end section 3'of the support column 3 is pivotally mounted about a first pivotal axis (SA1) on the base unit 2 and controlled by a first drive unit 8. A first end section 4' of the first robotic arm is pivotally mounted about a second pivotal axis (SA2) on the upper end section 4'' of the support column opposite to the base unit and controlled by a second drive unit. A first end section of the second robotic arm is pivotally mounted about a third pivotal axis (SA3) on a second end section of the first robotic arm by a third drive unit 10. Each drive unit is associated with a controllable magnetic brake unit 18,18* by which the robotic kinematics 3-5 can be uncoupled from the drive units 8-10.

Description

technical field [0001] The present application relates to an operator assistance system according to the preamble of claim 1 . Background technique [0002] Operator assistance systems are known, in particular for providing support for medical interventions or surgeries. Systems of this type are used, for example, to guide auxiliary equipment such as camera systems etc. [0003] As an example, DE102007019363A1 discloses an operation assistance system for guiding surgical or medical tools or equipment, by means of which an endoscope, for example comprising a camera unit, can be guided in a controlled manner. The example Manipulation assistance systems in include controlled robotic kinematics devices so that surgical or medical tools or equipment mounted on their free ends can move in three-dimensional space in a controlled manner. As an example, the robotic kinematics device comprising at least one support column, at least first and second robot arms, and at least one equip...

Problems solved by technology

In this situation, it is possible to move the drive unit using a hand force acting on the device held on the articulated arm. The disadvantage is that this articulated arm does not have any robotic kinematics, that is to say the medical device mounted on it Can only be controlled to a limited extent in three dimensions

However, this type of articulated arm is unsuitable for applications in minimally invasive surgery, especially for controlled guidance and tracking of the camera unit controlled by the operator.
