Registration Probe Motion Mapping for Sterile IGS Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interaction methods with image-guided surgery (IGS) navigation systems, such as keyboards, mice, and touchscreens, are cumbersome and compromise sterility during surgical procedures, requiring surgeons to leave the sterile field or rely on assistants, leading to inefficiencies and increased costs due to specialized device requirements.
Innovation Solution
A registration probe with integrated position sensors and non-contact motion tracking allows surgeons to interact with the IGS system by mapping movement patterns to control inputs, eliminating the need for direct contact and reducing the need for additional devices, thus maintaining sterility and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional interaction methods (keyboard, mouse, touchscreen) are used with IGS navigation system, then the system can be operated, but the surgeon must leave the sterile field or rely on assistants, compromising sterility and surgical efficiency
Solution Approach 1:
The patent introduces a foot pedal as an intermediary device that allows the surgeon to interact with the IGS navigation system without leaving the sterile field. The foot pedal acts as a mediator between the surgeon's commands and the system controls, maintaining sterility while enabling operation. This resolves the contradiction by providing a new interaction pathway that doesn't require the surgeon to contaminate the sterile field with hands or leave the area.
2Adaptability or versatility
If conventional interaction devices are used during surgery, then the IGS system can be controlled, but additional devices and personnel are required, increasing complexity and cost
Solution Approach 1:
The foot pedal is designed to perform multiple functions within the IGS system, including zooming, panning, and other navigation controls. This multi-functional device replaces the need for multiple separate interaction devices and assistants, reducing overall system complexity while maintaining full control capability. The single foot pedal interface provides versatile access to various system functions that would otherwise require multiple devices or personnel.
3Ease of operation
If surgeons interact with touchscreen or keyboard during procedure, then IGS navigation can be adjusted, but sterility must be compromised requiring re-sterilization or glove changes
Solution Approach 1:
The foot pedal serves as a sterile intermediary that allows surgeons to adjust IGS navigation settings without compromising the sterile field. By placing the control interface on the foot, which remains outside the sterile boundary, the system enables navigation adjustments while maintaining sterility requirements. This eliminates the need for re-sterilization or glove changes that would be required with hand-operated interfaces.

AI summary
Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.
