AI Technical Summary

Problems solved by technology

Commands such as "right" may correspond to moving the scope left and down, which can be highly counter-intuitive to an assistant and can lead to a trial and error approach
These issues can lead to extended operating room time and inefficient workflow

Embodiment Construction

[0016] In accordance with the present principles, embodiments directed to systems, devices, and methods provide guidance tools for manual manipulation of endoscopes. In one embodiment, pre-operative and / or intra-operative images are registered with endoscopic images. Visual cues can be superimposed onto the endoscopic view as a guidance tool to allow the user (eg, surgeon's assistant) to steer the endoscope toward a selected region of interest. The motion of the endoscope can be tracked in real time using image features to update the visual cues. The visual cues may include, but are not limited to: a direction indicator, which shows the direction to the selected region of interest; an endoscope tracker, which shows the motion of the endoscope; a direction error indicator, which shows angular error of the motion out of the endoscope compared to the direction to the selected region of interest; the distance error indicator, which shows the distance to the selected region of int...

Abstract

Systems and methods for guided endoscopic navigation include a registration module (118) configured to use a processor to align the first set of images (112) with the endoscope ( 102) of the second set of images (114) are registered. The selection module (120) is configured to receive a selected region of interest on the first set of images and transform the selected region of interest to an endoscopic coordinate frame. A guidance module (122) is configured to superimpose a guidance tool on the second set of images to allow a user of the endoscope to navigate to the selected region of interest.

Description

technical field [0001] The present disclosure relates to medical instruments, and more particularly to guide tools for manual manipulation of endoscopes. Background technique [0002] Coronary artery bypass grafting (CABG) is a surgical procedure used to revascularize blocked coronary arteries. Minimally invasive CABG is performed using the endoscope as the only feedback from the surgical site. In a standard setup for a minimally invasive CABG procedure, the surgeon holds the instrument with both hands while an assistant holds the endoscope. The endoscope is usually inserted into the chest cavity from the right side of the patient or from the front-to-back direction. This can result in three related coordinate systems: that of the endoscope (eg, camera), that of the surgeon, and that of the assistant. This can cause many problems. For example, while the surgeon is looking forward at the screen, the camera is showing anatomy from a side view. Also, if the camera located ...
