LAPAROSCOPIC INSTRUMENT FOR ACCURATE EXTRALUMENAL LOCATION OF A COLORECTAL TUMOR

The invention relates to a laparoscopic instrument which facilitates the accurate position of a tumor in the colon tract in the abdominal laparoscopic surgery and also with possible applications in open surgery. Precise location of a rectal tumor is required to decide the appropriate line of distal resection but current methods like bimanual palpation is approximatively and very subjective, lacking the needed “surgical” precision. The principle for precise identification of tumor location is that the tumor will be made “visible” for the laparoscopic instrument by placing sensing trackers close to its margins.
