Surgical Instrument Adapter With Interchangeable Mounting Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical adapter devices are typically specific to particular systems, limiting the versatility and compatibility of surgical instruments, and often require multiple specialized instruments for different procedures, increasing costs and complexity.
Innovation Solution
An adapter device with a modular design that includes an adapter member and an exchangeable mounting member, allowing interchangeable connection of various instruments, including those for navigation-assisted and robotic-assisted surgery, and capable of being used with standard connections like ¼ inch couplings, enabling the attachment of multiple instruments to a single surgical instrument, and allowing precise positioning and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adapter devices are specifically adapted to each other, then reliability of connection is improved, but adaptability is worsened
Solution Approach 1:
The adapter device incorporates a universal interface design with a mounting member that can interchangeably connect multiple different surgical instruments to a single surgical instrument shaft. The mounting member features a standardized connection interface that accommodates various instrument types including navigation instruments, robotic-assisted surgery instruments, and simple holding devices, allowing one adapter to serve multiple functions across different surgical systems
Solution Approach 2:
The adapter device acts as an intermediary component between the surgical instrument shaft and various additional instruments. The mounting member with its standardized interface mediates the connection, enabling instruments from different systems to be coupled to the shaft without requiring system-specific custom adapters, thus bridging compatibility gaps between different surgical systems
2Adaptability or versatility
If multiple specialized instruments are provided for different procedures, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
Instead of requiring separate specialized instruments for each surgical procedure, the invention provides a single surgical instrument shaft with a universal mounting member that can accommodate multiple different additional instruments. This allows the same basic shaft to be used across various procedures by simply changing the mounted instrument, reducing the total number of specialized instruments needed in the system
Solution Approach 2:
The surgical system is segmented into a reusable core component (the surgical instrument shaft with adapter) and interchangeable additional instruments. This segmentation allows the expensive or complex shaft to be retained and reused while only the smaller, procedure-specific additional instruments need to be changed, simplifying system management and reducing overall complexity
3Adaptability or versatility
If multiple specialized instruments are provided for different procedures, then adaptability is improved, but loss of substance is worsened
Solution Approach 1:
The universal mounting member allows a single surgical instrument shaft to perform multiple procedures by interchangeably mounting different additional instruments. This eliminates the need to purchase and maintain multiple complete specialized instrument systems, reducing overall system cost while maintaining the ability to perform various surgical procedures
Solution Approach 2:
The design enables recovery and reuse of the expensive surgical instrument shaft across multiple procedures and patients. Instead of discarding or dedicating entire instrument systems to single procedures, the shaft is recovered and reused with different additional instruments mounted for different procedures, maximizing resource utilization and reducing cost
