Portable Input Handle for Robotic Surgical Telementoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic surgical systems face challenges in providing effective training for novice clinicians, as hands-on experience is often limited due to time constraints and the need for expert surgeons to switch positions during procedures, making it difficult to offer comprehensive training in minimally invasive medical procedures.
Innovation Solution
A robotic surgical system with a first console, a second console, and a controller that includes a portable input handle with position and proximity sensors, allowing for the display of a virtual surgical tool on a display based on the pose of the portable input handle, enabling remote telementoring and improved training capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the novice clinician switches positions with the expert surgeon during the procedure, then the novice clinician gains hands-on training experience, but the procedure time is extended and procedural efficiency is reduced
Solution Approach 1:
The system creates a virtual copy of the surgical tool that is displayed on the display device, allowing the novice clinician to interact with a digital representation rather than requiring physical switching of positions. The virtual surgical tool replicates the functionality and visual appearance of the actual surgical tool, enabling training without interrupting the actual procedure.
Solution Approach 2:
The portable input handle serves as an intermediary device between the novice clinician and the surgical system. It transmits control signals to the controller, which then manipulates the virtual surgical tool display, allowing the novice to practice control without physically taking over the master console position.
2Duration of action of stationary object
If the expert surgeon remains at the console to provide continuous guidance, then training continuity is maintained, but the expert surgeon cannot provide hands-on experience
Solution Approach 1:
The system provides a virtual copy of the surgical tool through the display device that responds to inputs from the portable handle, allowing the novice clinician to gain hands-on experience with a digital representation while the expert surgeon remains at the master console providing continuous guidance and oversight.
3Adaptability or versatility
If a portable input handle with position sensor is used for remote telementoring, then training accessibility is improved, but device complexity increases
Solution Approach 1:
The portable input handle is designed to be a universal control device that can be used by multiple novice clinicians for telementoring sessions. It incorporates position sensing capabilities and communicates with the controller through wireless or wired connections, providing multiple functions in a single device including position tracking, signal transmission, and virtual tool control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and effective training by allowing master clinicians to provide remote guidance and visual feedback to novice clinicians, enhancing the learning experience without the need for physical presence and reducing the limitations of time and procedural interruptions.
Implementation Method 1
The second input handle includes a position sensor. The second console includes a position transmitter configured to receive pose data of the position sensor relative to the position transmitter
Implementation Method 2
the second input handle may include a proximity sensor configured to detect an object and, in response to a detection of an absence of the object, the controller may cause the display not to display the images of the surgical tool
Data Source
AI summary
Methods and systems are provided for facilitating telementored surgical procedures. The systems include a portable input handle further including a housing, a position sensor disposed adjacent to the housing, and a position transmitter in communication with the position sensor. The position sensor may be configured to sense a pose of the housing relative to the position transmitter. The position transmitter may be configured to receive and transmit the sensed pose of the housing to the robotic surgical system.
