Spinal Device Optics Carrier Pivoting Guideway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinal operation devices struggle to position the optics system close to the body surface due to the design requiring a larger overlap of the device body, limiting the depth of insertion and stability during surgical procedures.
Innovation Solution
A tubular device with a guideway element that allows the optics carrier to pivot and lock near the proximal end, reducing the overlap and enabling deeper insertion while maintaining stability through a swivel/lock mechanism and guide elements for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the optics carrier is slid onto the device body in the region of the proximal end, then the optics system can be mounted and moved about the longitudinal axis, but the device body must remain outside the body to be treated, limiting insertion depth
Solution Approach 1:
The device is divided into separate functional components: the device body for insertion and the optics carrier arrangement for positioning. The optics carrier arrangement includes a guideway element with a guideway region that can be positioned at the proximal end of the device body by pivoting, separating the mounting function from the insertion function. This allows the device body to extend deeper into the body while the optics system remains accessible outside.
Solution Approach 2:
The guideway element is designed to pivot about a swivel axis, introducing rotational movement in a different dimension. This allows the guideway region to be positioned at the proximal end of the device body through pivoting motion rather than linear sliding, enabling the optics carrier to be mounted close to the body surface while maintaining insertion depth.
2Ease of operation
If the optics carrier is positioned closer to the body surface, then access and positioning are improved, but the overlap region of the device body increases
Solution Approach 1:
The guideway element is designed with movable components including a movable optics carrier that can be positioned along the guideway region. The swivel bracket element allows the guideway element to pivot into position, creating a dynamic positioning system rather than a fixed structure. This enables the optics system to be easily accessed and positioned while minimizing the static overlap region of the device body.
3Length of moving object
If the device body is inserted deeper into the body, then surgical access is improved, but the region outside the body becomes shorter for optics positioning
Solution Approach 1:
The guideway element acts as an intermediary component between the device body and the optics carrier. It provides a guideway region that can be positioned at the proximal end of the device body through pivoting motion, serving as a mediator that allows deep insertion while maintaining external access points for the optics system through the swivel bracket mechanism.
