AI Technical Summary

Technical Problem

Conventional trocars are inserted 'blindly' into the body, making it difficult for physicians to accurately locate the distal end during invasive procedures, and existing solutions are costly due to the need for multiple types of trocars with integrated cameras and sensors for different tissue types.

Method used

A navigated trocar with an internal camera and position sensor, allowing real-time image guidance and position tracking, combined with modular obturator heads for different tissue types, reduces costs by allowing reuse of the obturator heads and using a disposable proximal end with a camera and sensor.

Benefits of technology

Enables precise visualization and tracking of the trocar's position within the body, improving the quality of minimally invasive procedures while reducing the expense associated with custom trocars for various tissue types.

Abstract

A trocar for insertion into an organ of a patient includes a cannula, a channel inside the cannula, and a camera. The cannula has a longitudinal axis, and the channel inside the cannula is fitted parallel to the longitudinal axis. The camera is disposed at a distal end of the channel and is configured to provide images in a direction of a distal opening of the cannula.
