Trans-Platform Surgical Apparatus Minimizing Incision Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional minimally invasive surgical apparatuses face challenges in inserting large therapeutic tools due to size constraints and complex power transmission systems, leading to increased pain, bleeding, and prolonged recovery times, as well as limitations in the number and size of working devices that can be simultaneously inserted through minimal openings.
Innovation Solution
A trans-platform apparatus featuring a cylindrical main platform with longitudinally arranged working devices and integrated spin shafts that enable vertical and rotational motions, allowing for the simultaneous insertion and reconfiguration of multiple working devices through minimal openings, eliminating the need for separate connection members and simplifying power transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the main tube includes an inner tube and an outer tube to enable three-dimensional surgery, then the structural stability is improved, but the radius of the therapeutic tool which can be mounted becomes much smaller
Solution Approach 1:
The apparatus is divided into a main tube and a separate spin shaft that can be independently inserted and coupled. The spin shaft is inserted through the inner tube and coupled to the therapeutic tool, allowing the tool to have a larger radius than the inner tube while maintaining structural stability through the dual-tube configuration.
Solution Approach 2:
The spin shaft is inserted through the inner tube in a longitudinal direction and then coupled to the therapeutic tool, utilizing the longitudinal dimension to accommodate a larger-radius tool without increasing the cross-sectional dimensions of the inner tube. This dimensional approach allows the therapeutic tool radius to exceed the inner tube radius.
2Ease of operation
If the therapeutic tool and spin shaft are connected through a separate connection member with power transmission, then the operational control is improved, but the power transmission apparatus must be miniaturized
Solution Approach 1:
The connection member integrates both mechanical coupling and power transmission functions into a single component. The spin shaft itself serves as both the connection element and the power transmission element, eliminating the need for separate miniaturized power transmission apparatus while maintaining operational control.
3Object-affected harmful factors
If multiple working devices are inserted through minimal openings for minimally invasive surgery, then the surgical trauma is reduced, but the number and size of working devices that can be simultaneously inserted is limited
Solution Approach 1:
The working devices are segmented into two insertion paths: larger devices through the main tube opening and smaller devices through the inner tube opening. This segmentation allows multiple devices of different sizes to be simultaneously inserted through minimal openings, reducing surgical trauma while increasing the number and size of working devices.
Solution Approach 2:
The apparatus utilizes two different opening dimensions: a larger opening in the main tube for larger working devices and a smaller opening in the inner tube for smaller working devices. This multi-dimensional opening configuration enables simultaneous insertion of multiple working devices with different size requirements through minimal openings.
