Problems solved by technology

[0004] A disadvantage of the camera systems or endoscopes described in the prior art is that the endoscope is only set up for displaying the surgical field, due to the position of the surgical instruments and the position of the endoscope close to the surgical procedure and the field of view angle (FoV, A variation of the "Field of View), the endoscope is however not capable of simultaneously imaging the position and orientation of surgical instruments introduced into the abdominal cavity, where only the area near the surgical procedure is imaged

Embodiment Construction

[0035] figure 1 A multi-camera system according to the invention is shown. Through the body tissue 2 and into the patient's body via the cannula 1a. Through the cannula 1a, an additional carrier 3 for a 2D overview camera can be introduced into the body. The additional carrier 3 is designed in such a way that it can realize a tubular feedthrough for a rotationally symmetrical further main carrier 4 a of rod-like design for the surgical instrument. The camera holder 5 is fastened on the additional carrier 3 via joints 6 such that after passing through the sleeve 1 a it can be pivoted outwards by essentially 90° relative to the axis of rotation by means of a pivoting movement 7 . The camera mount 5 carries an additional image sensor, which is formed by an image sensor 9 and a wide-angle imaging optics 8 with an aperture angle 18 . In order to illuminate the field of view, the camera holder 5 is also equipped with an additional lighting unit, which is formed from a light sourc...

Abstract

The present invention relates to a surgical robot system with at least two robot arms (45, 47, 49, 51), on each of which is arranged at least one endoscope for a minimally invasive surgery, wherein the first endoscope on the first robot arm (47) comprises a main support means (4b) and which comprises at the distal end at least one lighting unit (23, 24) and two image-taking devices (20a, 21a, 22a, 20b, 21b, 22b), and a trocar (1b), and wherein the second endoscope on to the second robot arm (45) comprises a main support means (4a), a trocar (1a), and an auxiliary support means (3).

Description

technical field [0001] The invention relates to a multi-camera system comprising at least one endoscopic camera and at least one cannula camera for use in minimally invasive surgery and in a corresponding surgical robot, in particular for use in minimally invasive surgery , such as in laparoscopy. Background technique [0002] Minimally invasive surgical procedures, such as laparoscopic procedures, are performed through the use of surgical instruments, such as clamps, knives, and suturing tools, which are introduced into the patient's body through one or more cannulae. Typically, two to four, in most cases three surgical instruments are used. What is required in addition to the surgical instrument is the presence of a display unit which enables the surgeon to view the operating field. Such a display unit is usually a camera or an endoscope, which is likewise introduced into the patient's body via a cannula. Usually, the visualization takes place via an endoscope, which sh...
