Device for intracorporal, minimal-invasive treatment of a patient
First Claim
1. A device for intracorporal, minimal-invasive treatment of a patient, comprising:
- a working instrument that can be introduced into a body cavity of said patient for carrying out a treatment step, said working instrument having a distal end defining an intracorporal working area when said working instrument is introduced in said body cavity;
at least one image pick-up unit for picking up an image of said intracorporal working area, said image pick-up unit having an optical axis; and
positioning means for orienting said optical axis of said image pick-up unit in dependency on a spatial position of said intracorporal working area, said positioning means further comprising;
a guide shaft in which said working instrument is guided, said guide shaft having an intracorporal portion, and a holder pivotably fixed to said intracorporal portion of said guide shaft, wherein said image pick-up unit is arranged at said holder in a distance from a location where said holder is linked to said guide shaft, such that said image pick-up unit is intracorporally pivotable into a working position, in which said optical axis runs angularly to a longitudinal center axis of said guide shaft and points to said longitudinal center axis.

Abstract
The present invention describes a device for intracorporal, minimal-invasive treatment of a patient, comprising a working instrument that can be introduced into a body cavity of the patient for carrying out a treatment step, wherein a distal end of the introduced working instrument defines an intracorporal working area, and at least one image pick-up unit for picking up an image of the intracorporal working area, further comprising positioning means for orienting an optical axis of the image pick-up unit in dependency on a spatial position of the intracorporal working area, wherein the positioning means comprise a guide shaft, in which the working instrument is guided, and wherein the image pick-up unit is pivotably fixed at an intracorporal portion of the guide shaft. The positioning means have a holder pivotably fixed to the intracorporal portion of the guide shaft, the image pick-up unit being arranged at the holder in a distance from a location where the holder is linked to the guide shaft, such that the image pick-up unit is intracorporally pivotable into a working position, in which the optical axis runs angularly to a longitudinal center axis of the guide shaft and points to the longitudinal center axis.
