Collapsible Prosthesis Delivery Sleeve for Small-Incision Implant Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inserting prosthetic implants through small surgical incisions are time-consuming, increase infection risk, and result in implant damage due to manual manipulation and the need for single-use sleeves, while lubrication distribution is uneven, prolonging surgery time and increasing costs.
Innovation Solution
A collapsable prosthesis delivery apparatus with a tapered design, expandable opening, and channels for lubricant distribution, allowing multiple uses and even lubrication, reducing manual manipulation time and minimizing implant damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If hand manipulation is used to guide the implant through the incision, then the implant can be inserted through a small incision, but the surgical time increases significantly
Solution Approach 1:
A delivery device is introduced as an intermediary tool between the surgeon and the implant. The device includes a delivery tube with a distal end that can be inserted through a small incision, and the implant is loaded into the delivery tube. The surgeon manipulates the delivery device rather than directly manipulating the implant, enabling controlled insertion through small incisions while reducing surgical time.
Solution Approach 2:
The implant is pre-loaded into the delivery tube before the surgical procedure begins. This preliminary preparation eliminates the time-consuming manual manipulation step during surgery, as the implant is already positioned and ready for insertion through the small incision.
2Device complexity
If direct hand manipulation is used, then no additional equipment is needed, but the risk of implant damage increases
Solution Approach 1:
The delivery device serves as a protective intermediary that interfaces with the implant. The delivery tube provides a controlled environment for implant insertion, preventing direct contact between the surgeon's hands and the implant surface, thereby reducing the risk of contamination and damage while maintaining reasonable equipment simplicity.
3Loss of time
If a sleeve is used to slide the implant through the incision, then insertion time is reduced, but the sleeve must be discarded after single use
Solution Approach 1:
The delivery device is designed to be reusable rather than disposable. After the implant is delivered, the delivery tube can be cleaned and sterilized for subsequent uses. This recovery and reuse of the delivery device eliminates the waste associated with single-use sleeves while maintaining the time-efficient insertion method.
Solution Approach 2:
The delivery device is designed with universal applicability to accommodate different implant sizes and types. The delivery tube can be adjusted or selected in different sizes, and the same basic device structure serves multiple surgical procedures, reducing the need for multiple disposable sleeves.
4Ease of operation
If lubricant is applied to reduce friction, then implant insertion is facilitated, but uneven distribution increases surgical time
Solution Approach 1:
Lubricant is pre-applied to the delivery tube and/or implant before assembly. This preliminary lubrication ensures even distribution of the lubricating agent, facilitating smooth insertion without requiring additional time during the surgical procedure to apply or redistribute the lubricant.
