Deployable Probe and Blade for Obstructed Target Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld cutting instruments lack the ability to accurately and specifically cut targets that are obstructed from view, as they require direct access and visual or physical alignment, which is not possible in all scenarios, especially in minimally invasive surgical procedures like carpal tunnel release surgery.
Innovation Solution
A handheld apparatus with a deployable probe and blade that includes a probe with a target interaction surface and a cutting edge, allowing for selective movement between retracted and extended positions, enabling precise targeting and cutting without direct line of sight, suitable for use in minimally invasive surgical procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a general cutting tool is adapted for a particular purpose, then the tool can perform the cutting function, but it requires direct visual or physical access to the target object for accurate cutting
Solution Approach 1:
The patent introduces an intermediary imaging system (endoscope, ultrasound, or other imaging devices) that mediates between the surgeon and the target object. This imaging system provides visual or physical information about the target object's location and characteristics without requiring direct line-of-sight access, enabling accurate cutting of obstructed targets while maintaining the versatility of the cutting tool for different surgical applications
2Ease of manufacture
If direct line of sight is required for cutting, then the cutting can be performed with simple tools, but accurate cutting of obstructed targets becomes impossible
Solution Approach 1:
An imaging intermediary system is introduced to provide precise information about the target object's location, size, and characteristics. This intermediary delivers measurement data without requiring complex modifications to the cutting tool itself, maintaining tool simplicity while achieving accurate targeting of obstructed objects through the imaging system's mediation
3Measurement precision
If imaging technologies are used to locate targets, then accurate cutting of obstructed targets becomes possible, but the cost and complexity of the system increases
Solution Approach 1:
The patent designs the cutting tool with multi-functionality, integrating both the cutting function and the ability to work with imaging intermediaries. The tool is configured to receive imaging information from various sources (endoscopes, ultrasound devices, or other imaging systems) and translate this information into accurate cutting guidance, eliminating the need for separate specialized equipment and reducing overall system complexity while maintaining high measurement precision

AI summary
A device includes a handle, an apparatus for probing and cutting, and an adaptor. The handle includes one or more triggers. The apparatus for probing and cutting is connectable to the handle and includes an elongated member, a probe, and a blade. The probe and the blade are selectively deployable from the elongate member via activation of the one or more triggers on the handle. The adaptor is configured to selectively connect the apparatus to the handle in a predetermined orientation.
