Modular Surgical Guide With Interchangeable Collets for Spinal Robotics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical treatments for spinal disorders, such as degenerative disc disease and osteoporosis, often require multiple instruments and implants, which can complicate the surgical process and disrupt the sterile field, while current surgical instruments lack versatility for accommodating various sizes and types of surgical tools during a single procedure.
Innovation Solution
A modular surgical guide system that includes a body with interchangeable collets and extenders, allowing for multiple surgical instruments to be used with a single surgical robot, maintaining sterility and facilitating efficient instrument changes during spinal surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple instruments are used in spinal surgery, then surgical versatility is improved, but device complexity increases
Solution Approach 1:
The surgical guide body is designed with a universal interface that accepts multiple types of surgical instruments through interchangeable collets. The single guide body can accommodate different instrument types (screwdrivers, drivers, reamers) by simply changing the collet, eliminating the need for multiple specialized guides and reducing overall device complexity while maintaining high versatility.
Solution Approach 2:
The system is divided into modular components: a permanent guide body and interchangeable collets. Each collet is a separate segment that can be independently selected and attached to the guide body. This segmentation allows the system to adapt to different surgical needs by combining the universal guide body with specific collet components, reducing the total number of instruments needed.
2Adaptability or versatility
If multiple instruments are used in spinal surgery, then surgical versatility is improved, but loss of time increases
Solution Approach 1:
Multiple collets are prepared in advance and can be pre-loaded into the guide body or kept in a sterile tray ready for immediate attachment. The guide body is designed with a pre-configured interface that allows for rapid collet changes without requiring complex assembly procedures. This preliminary preparation and simplified interface reduce the time lost during instrument changes while maintaining the ability to use multiple instrument types.
3Adaptability or versatility
If multiple instruments are used in spinal surgery, then surgical versatility is improved, but device complexity increases
Solution Approach 1:
The guide body incorporates a universal interface design that works with all collet types. The interface includes standardized features such as a uniform bore, consistent retention mechanisms (screw or friction fit), and aligned tooling surfaces. This universality simplifies the operator's task by providing a single, intuitive attachment method for all instruments, improving ease of operation despite the variety of tools available.
