Suturing Instrument for Minimally Invasive Pelvic Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for treating pelvic conditions such as incontinence and prolapse are often invasive and require lengthy recovery periods, with a need for more minimally invasive and effective methods and instruments.
Innovation Solution
Development of surgical tools and methods for sacral colpopexy procedures, including a suturing instrument for semi-automated, one-handed operation and a suture passer that allows for easy suture deployment through tightly confined spaces using a curved needle with a hook tip and a hypo tube for pressurized suture injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures are used to treat pelvic conditions, then effective treatment can be achieved, but the procedures are invasive and require lengthy recovery periods
Solution Approach 1:
The patent changes the physical parameters of the surgical approach by transitioning from open surgical incisions to percutaneous needle-based delivery. This parameter change enables the same therapeutic effect (mesh attachment to sacrum) to be achieved through a minimally invasive route, thereby maintaining treatment effectiveness while reducing invasiveness and recovery time
2Reliability
If sacral colpopexy procedures are performed to treat vaginal vault prolapse, then effective repair can be achieved, but the procedures are complicated and require lengthy surgical times
Solution Approach 1:
The patent extracts the essential therapeutic function (attaching mesh to sacrum) from the complex traditional surgical procedure. By using a needle-based delivery system that can be guided to the sacrum through minimal access points, the core function is isolated and simplified, eliminating unnecessary surgical steps and reducing overall procedure time while maintaining repair effectiveness
3Strength
If traditional suturing methods are used in pelvic procedures, then adequate tissue attachment can be achieved, but the suturing process is time-consuming and difficult to control
Solution Approach 1:
The patent replaces the traditional mechanical suturing system (needles, threads, manual stitching) with a controlled delivery mechanism that uses a needle guide and pushrod system. This substitution allows for more precise control of the attachment process, reduces the time required to achieve adequate tissue attachment strength, and improves overall suturing efficiency through a more systematic approach
