Abstract
A positioning unit for guiding a medical object such as a needle includes a securing unit by which the positioning unit may be arranged on the medical object. In order to enable an improved guidance for the medical object, an indicating element with a plurality of indicators is provided. The indicating element is arranged in a fixed position relative to the securing unit. An acquisition unit acquires an item of movement information. The positioning unit is configured to control the plurality of indicators dependent upon the movement information.
Claims20
A positioning unit for guiding a medical object, the positioning unit comprising:
- a securing unit, by which the positioning unit is arrangeable on the medical object;
- an indicating element that is arranged in a fixed position relative to the securing unit, the indicating element comprising:
- two plates that are each arrangeable on the medical object by a respective part of the securing unit independently of one another, and
- a plurality of indicators, wherein at least three first indicators of the plurality of indicators are arranged on a first of the two plates, and at least three second indicators of the plurality of indicators are arranged on a second of the two plates, and wherein the securing unit is arrangeable on the medical object such that the medical object extends through the first plate between one of the at least three first indicators and another of the at least three first indicators and through the second plate between one of the at least three second indicators and another of the at least three second indicators;
- and
- an acquisition unit for acquiring an item of movement information,
- wherein the positioning unit is configured to control the plurality of indicators dependent upon item of the movement information.
A positioning system comprising:
- a positioning unit for guiding a medical object, the positioning unit comprising:
- a securing unit, by which the positioning unit is arrangeable on the medical object;
- an indicating element that is arranged in a fixed position relative to the securing unit, the indicating element comprising:
- two plates that are each arrangeable on the medical object by a respective part of the securing unit independently of one another, and
- a plurality of indicators, wherein at least three first indicators of the plurality of indicators are arranged on a first of the two plates, and at least three second indicators of the plurality of indicators are arranged on a second of the two plates, and wherein the securing unit is arrangeable on the medical object such that the medical object extends through the first plate between one of the at least three first indicators and another of the at least three first indicators and through the second plate between one of the at least three second indicators and another of the at least three second indicators;
- and
- an acquisition unit for acquiring an item of movement information, wherein the positioning unit is configured to control the plurality of indicators dependent upon the item of movement information;
- a sensor unit configured to acquire a position, orientation, or position and orientation of the positioning unit;
- and
- a processor configured to determine the movement information dependent upon the acquired position, orientation, or position and orientation of the positioning unit and a target position.
