Interchangeable Surgical Hand Tool With Friction-Lock Jaws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for interchangeable surgical tools are limited to electrically-powered devices and specific applications, lack versatility, and have cumbersome interchangeability systems, particularly for mechanically operated tools that require fast part replacement and are suitable for diverse medical procedures.
Innovation Solution
A hand tool device with adjustable, interchangeable jaws and handles connected via a central pivot and threaded screw-type connectors, allowing for quick tool changes and suitable for both surgical and non-surgical applications, with an optional spring for tension and ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pin system is used for tool interchangeability, then the device can be universal and interchangeable, but the tool change process becomes slow and cumbersome and small parts may be lost
Solution Approach 1:
The patent removes small intermediary parts (pins, clips, screws) from the interchangeability system. Instead, it uses a direct friction-fit interface where the tool head inserts into the handle and is retained by friction alone, eliminating components that could be lost and simplifying the exchange process to a single motion.
Solution Approach 2:
The friction-fit interface is self-retaining and self-locking without requiring additional fastening components. The tool head automatically secures itself in the handle through friction when inserted, and can be removed by simple manual manipulation, making the system self-sufficient without small parts.
2Extent of automation
If electrically-powered devices are used for interchangeable tools, then automated tool changes are possible, but the devices cannot be used for mechanically operated tools and have limited applications
Solution Approach 1:
The patent creates a universal mechanical interface that works with any manually operated tool requiring a handle and gripping action. The same friction-fit system can accommodate scissors, forceps, clamps, and other surgical or non-surgical tools, making the system applicable across diverse manual procedures without requiring electrical components.
3Area of stationary object
If a limited array of tools is kept within easy reach, then space requirements are reduced, but the selection may not be adequate for all surgical situations
Solution Approach 1:
The patent segments the tool system into a permanent handle component and interchangeable tool head components. This allows the surgical team to keep a compact set of handles with universal interfaces while being able to quickly swap tool heads to match specific surgical needs, effectively expanding the functional toolkit without increasing storage space for multiple complete tools.
