Automated Realtime Imaging for Laparoscopic Interventions

Project title

DFG LU604/27-2 Automated Realtime Imaging for Laparoscopic Interventions

Goal

Improvement of single incision laparoscopic surgery both in the field of tissue manipulation as well as in the field of intraoperative imaging and visualization of information

Contact

Dipl.-Ing. Sandra Brecht (wiss. Mitarbeiter)

Application

Laparoscopic procedures, especially the resection of deep-seated tumors, for example laparoscopic partial nephrectomy

Research topic

Manipulator system for single incision laparoscopic surgery integrating augmented reality features

State of the art

Manipulation with laparoscopic instruments
Laparoscope (and laparoscopic ultrasound probe) for visualization

Drawbacks of the State of the Art

Restricted instrument handling due to the limited access using only one skin incision
Only superficial imaging with the laparoscope
Images from the laparoscope and the ultrasound system are displayed on separate screens and have to be matched to the anatomical context in mind, which is challenging and error-prone

Concept

Selective laser sintered Single Incision Laparoscopic Manipulator for bimanual manipulation and guidance of an ultrasound probe integrating augmented reality features by superimposing additional information gained with the ultrasound probe onto the laparoscopic image

Current Results

Prototype of the Single Incision Laparoscopic Ultrasound Manipulator System
