Abstract

The invention relates to a device for controlling corporeal structures, especially for introducing puncture needles or operation probes. Said device comprises a base plate (1), at least one base holder (2) applied to the base plate (1), and holding rods (3, 4) that are fixed to the base holder in a fixed manner and are used to hold and position a targeting device (10) for a medical instrument (8). The aim of the invention is to create one such device in such a way that it has a simple structure and can guide medical instruments in a variable and precise manner. To this end, the targeting device (10) is mounted on two adjustment arms (7) that can be respectively displaced in the X and/or Y plane, on the free ends of the holding rods (3, 4), by means of an actuating drive (6).

Claims

1. An apparatus for controlling corporeal structures, especially for introducing puncture needles or operation probes, comprising a base plate, at least one base holder applied to the base plate and holding rods attached thereto in an articulated manner for holding and positioning a targeting device for a medical instrument, characterized in that the target device is mounted on two adjustment arms which are each movable by means of an actuating drive on the free ends of the holding rods in the X- and/or Y-plane.

2. An apparatus according to claim 1, characterized in that the adjustment arms are bent towards the patient.

3. An apparatus according to claim 1, characterized in that a guide tube for the medical instrument is mounted on the free ends of the adjustment arms, especially by way of ball heads.

4. An apparatus according to one of the claims claim 1, characterized in that the base plate comprises a scaffold- or portal-like frame.

5. An apparatus according to claim 4, characterized in that the base plate comprises marking for repositioning the frame which can be fastened to the base plate in a magnetic, pneumatic or mechanical manner.

6. An apparatus according to claim 1, characterized in that the two actuating drive are arranged directly above one another and are preferably arranged as flat boxes.

7. An apparatus according to claim 1, characterized in that the actuating drives each comprise a compound slide for the adjustment of the respective adjustment arm in the X-Y plane, especially with remote-controllable threaded spindles.
