Modular Incision Tool for Precise Minimally Invasive Prosthetic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive surgical suturing devices are not compatible with prosthetic devices, requiring manual adaptation of sutures, which increases cardio-pulmonary bypass (CPB) time and risks, and there is a need for efficient incision tools to reduce surgical staff exposure to sharp instruments.
Innovation Solution
A modular surgical apparatus with a base, pivots, alignment tabs, and a blade mechanism, compatible with minimally invasive tools, for precise incisions, and a prosthetic suturing device with a guide tip and needle system for efficient suture management through prosthetic sewing cuffs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If current surgical suturing devices are used with prosthetic devices, then the suturing process becomes manual and time-consuming, but the device complexity and adaptability are limited
Solution Approach 1:
The prosthetic suturing device is designed with a universal interface that accepts both traditional suturing needles and suture adapters from minimally invasive surgical devices. The guide tip incorporates a receiving structure that can accommodate different needle types and adapter configurations, allowing the same device to perform both manual suturing and automated adapter-based suturing without requiring separate specialized tools for each function.
Solution Approach 2:
The suturing device is divided into modular components including a handle, guide tip, and needle receiving mechanism that can be independently configured. The guide tip can be detached and replaced or adjusted to accept different needle sizes and adapter types, allowing the system to be adapted to various prosthetic devices and suring requirements without redesigning the entire system.
2Loss of time
If manual suturing methods are used for prosthetic devices, then adaptability to different suture types is maintained, but the cardio-pulmonary bypass time increases
Solution Approach 1:
A suture adapter serves as an intermediary component that bridges the minimally invasive suturing device and the prosthetic device sewing cuff. The adapter includes a coupling mechanism that attaches to the suture end and a interface that engages with the guide tip, enabling the minimally invasive device to manipulate and pass sutures through the prosthetic sewing cuff without requiring manual needle threading, thereby reducing surgical time while maintaining ease of operation.
3Adaptability or versatility
If suture adapters are cut off and re-threaded manually, then compatibility with prosthetic devices is achieved, but the overall surgical time increases
Solution Approach 1:
The suture adapters are pre-configured with coupling mechanisms and interface features that are ready for direct attachment to the guide tip without requiring cutting or re-threading. The adapters come pre-assembled with sutures attached and pre-formed engagement structures that match the guide tip receiving mechanism, eliminating the time-consuming manual preparation steps while maintaining full compatibility with prosthetic devices.
