Universal Handpiece for Navigated Surgical Drills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigated surgical tools are limited in flexibility, as they often require specific vendor-provided drills and tracking systems, restricting surgeons' ability to use their preferred equipment with existing surgical navigation systems.
Innovation Solution
A handpiece and navigated surgical tool kit that includes a retaining member, guard, mounting member, and actuator, allowing user-selected surgical drills to be configured with a tracking system and navigation software, providing flexibility and compatibility with various tools and software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional navigated surgical tools use vendor-provided drills and tracking systems, then system reliability is improved, but adaptability deteriorates
Solution Approach 1:
The handpiece is designed as a universal interface that can accommodate multiple types of surgical drills and tracking systems through standardized mounting mechanisms. The retaining member and mounting member are configured to work with various tool configurations, allowing a single handpiece design to serve multiple functions and integrate with different vendor equipment while maintaining system reliability
Solution Approach 2:
The handpiece acts as an intermediary device between the surgical tools and the navigation system. It provides standardized interfaces and mounting mechanisms that mediate between proprietary tool designs and the navigation system requirements, enabling compatibility without compromising the reliability of either component
2Manufacturing precision
If a fixed target robotic navigation system is used, then cutting precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system separates the functions of precision positioning (handled by the robotic arm with fixed target) from tool control (handled by the handpiece interface). This segmentation allows the robotic component to maintain high cutting precision while the handpiece provides familiar freehand operation controls, improving ease of operation without sacrificing precision
Solution Approach 2:
The system transitions from completely fixed robotic positioning to a hybrid approach where the robotic arm provides guided positioning but the surgeon maintains dynamic control through the handpiece. This dynamic control allows adaptation to real-time surgical conditions while preserving the precision benefits of robotic guidance

AI summary
A handpiece arrangement for a tool having a retaining member configured to receive a portion of the tool in a secure position, a guard configured to cover a portion of the tool, at least one mounting member configured to receive a portion of a tracking system and an actuator mounted to the handpiece. The actuator may be configured to control the exposure of the tool. A navigated surgery kit is also provided including a tracking system, a tool in communication with the tracking system, a platform in communication with the tracking system and the tool. The platform may have a processor, a computer readable storage medium having computer readable program code configured to selectively control shaping of an object with the tool via at least one hidden object associated with a predetermined navigated surgical operation.
