Surgical Guide Release Mechanism for Stuck Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical systems for treating spinal disorders face challenges with surgical instruments becoming fixed, frictionally fixed, stuck, galled, or jammed during robot-assisted spinal implant procedures, leading to increased component manipulation time and potential procedural complications.
Innovation Solution
A surgical guide system with a release mechanism, such as a rescue wheel, that allows for the removal of fixed surgical instruments from a surgical robot, facilitating quick replacement and reducing manipulation time, including a clamp screw accessible through non-conventional access points and a flush-oriented release actuated by a surgical driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If surgical instruments are used in robot-assisted spinal implant procedures, then surgical precision and automation are improved, but instruments may become fixed, frictionally fixed, stuck, galled, or jammed during procedures
Solution Approach 1:
The surgical guide acts as an intermediary device between the robotic system and the surgical instrument. It provides a controlled interface that allows the instrument to be retained by the robotic system while enabling manual access through openings and slots for release mechanisms, thus mediating between automated positioning and manual intervention needs
Solution Approach 2:
The surgical guide is divided into functional segments: a body for instrument retention, openings for screw access, and slots for release mechanism access. This segmentation allows different parts of the device to serve distinct functions - maintaining instrument security while enabling controlled manual access when needed
2Stability of the object's composition
If surgical instruments become fixed or stuck during procedures, then instrument stability is improved, but component manipulation time increases and procedural complications arise
Solution Approach 1:
The release mechanism is pre-configured within the surgical guide structure, with openings and slots positioned for direct access. The clamp screw and release wheel are arranged in advance to enable quick manual intervention without requiring complex disassembly or time-consuming manipulation when instrument release is needed
Solution Approach 2:
The release mechanism extracts the stuck instrument from the surgical guide by providing direct access points through openings and slots. The release wheel and clamp screw can be manually operated to disengage the instrument retention mechanism, effectively removing the instrument from the guide without requiring complete system disassembly
3Ease of operation
If a release mechanism is added to allow removal of fixed instruments, then instrument removal capability is improved, but device complexity increases
Solution Approach 1:
The surgical guide provides self-service functionality by integrating the release mechanism directly into its structure. The openings and slots are positioned to allow direct manual access to the clamp screw and release wheel, enabling the device to be released without requiring external tools or complex manipulation procedures
Solution Approach 2:
The release mechanism is merged with the surgical guide body structure. The openings for screw access and slots for release wheel access are integrated into the guide's architecture, combining the retention and release functions into a single unified device rather than separate components
