Needle-Transfer Suturing Device for Percutaneous Native Tissue Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical treatments for urinary incontinence and pelvic organ prolapse, such as abdominal and transvaginal surgeries, are invasive and often require artificial mesh implants, which can be difficult and pose complications.
Innovation Solution
A suturing device with a fixed arm, movable jaw, and needle transfer mechanism that allows for precise suturing and securement of needles in multiple positions, enabling minimally invasive procedures using native tissue repair without artificial mesh.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional abdominal or transvaginal surgery with artificial mesh is used to treat urinary incontinence and pelvic organ prolapse, then surgical effectiveness can be achieved, but the procedure becomes invasive and carries higher complication risks
Solution Approach 1:
The invention changes the fundamental parameter of surgical approach from invasive (abdominal/transvaginal) to minimally invasive (percutaneous). The suturing device delivers sutures through small puncture sites in the abdominal wall, transforming the surgical pathway without compromising the ability to achieve effective tissue approximation and organ support.
Solution Approach 2:
The invention extracts and eliminates the need for artificial mesh implants by using pure native tissue repair. The percutaneous suturing device directly approximates abdominal wall tissues and supports pelvic organs using only the patient's own tissues, removing the harmful element of foreign body implants while maintaining surgical effectiveness.
2Strength
If artificial mesh implants are used for repair, then structural support can be provided, but the device complexity and potential for complications increase
Solution Approach 1:
The invention removes artificial mesh from the surgical system entirely. The suturing device creates structural support exclusively through native tissue approximation, eliminating the complex multi-component mesh implantation system and reducing overall device complexity while maintaining the necessary structural support for organ prolapse repair.
Solution Approach 2:
The invention enables native tissues to provide their own structural support through direct approximation and healing. Rather than requiring artificial mesh to provide strength, the patient's own tissues are sutured together to create the necessary structural integrity, allowing the biological system to serve itself in the repair process.
3Object-affected harmful factors
If percutaneous suturing with native tissue repair is performed, then invasiveness is reduced, but surgical precision and needle control become more difficult
Solution Approach 1:
The invention introduces a specialized suturing device as an intermediary tool that bridges the gap between percutaneous access and precise tissue approximation. The device includes needle drivers, suture passers, and tissue graspers that enable accurate needle placement and suture delivery through small puncture sites, maintaining surgical precision despite the minimally invasive approach.
Solution Approach 2:
The suturing process is segmented into discrete, controllable steps: puncture site creation, needle insertion, suture passage, and tissue approximation. Each step is facilitated by specialized components of the suturing device that provide precise control and feedback, allowing the surgeon to maintain accuracy throughout the minimally invasive procedure.
