Solution Overview

Problem

Existing surgical methods for suturing prosthetics to human tissue, such as in sacrocolpopexy procedures, face challenges including limited visibility, tissue handling difficulties, and anatomical variability, which affect the durability and efficacy of support for prolapsed organs.

Innovation Solution

A method involving endomechanical suturing using a surgical tool with deployment members to secure prosthetics, such as mesh materials, to human tissue by deploying fasteners through the prosthetic and into the tissue, allowing for secure fixation without manual needle handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional separate suture passing through mesh and tissue is used, then the surgical procedure can be performed with simple tools, but the attachment durability and precision are compromised

Engineering Contradiction:

Improveattachment durabilityVSAvoidsurgical tool complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the suture, needle, and deployment mechanism into a single integrated surgical tool assembly. The needle is attached to the suture within the elongated member, and the deployment mechanism integrates multiple functions (suture advancement, needle deployment, suture release) into one device, eliminating the need for separate manual passing of sutures through mesh and tissue

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary deployment mechanism that acts as a mediator between the surgeon's control and the suture-tissue-mesh attachment process. The deployment mechanism includes features like the deployment member, lateral side, and release features that mediate the complex actions of penetrating tissue, securing mesh, and releasing the suture in a controlled sequence

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If laparoscopic approach with small incisions is used, then patient trauma is reduced, but visibility and tissue handling become difficult

Engineering Contradiction:

Improvepatient traumaVSAvoidtissue handling

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent replaces manual tissue handling and suture passing with a mechanically actuated surgical tool that can be controlled through the laparoscopic port. The elongated member with deployment mechanism allows automated or semi-automated suture deployment, reducing the need for direct manual manipulation of tissues through small incisions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The surgical tool is segmented into distinct functional components (elongated member, deployment mechanism, needle, suture) that can be independently controlled and deployed. This segmentation allows the surgeon to perform complex tissue attachment tasks through a small incision by controlling individual components of the tool rather than requiring large exposure for manual manipulation

Inventive Principle:

Principle #1Segmentation

3Measurement precision

If in-situ suturing is performed manually, then the procedure can be done with basic surgical instruments, but precision and control are limited

Engineering Contradiction:

Improvesuture placement precisionVSAvoidsurgical tool complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The surgical tool is pre-configured with the suture attached to the needle within the elongated member before the surgical procedure. The deployment mechanism is pre-designed with specific geometric features (lateral side, deployment member, release features) that ensure precise suture placement and controlled deployment sequence, eliminating the need for manual measurement and positioning during surgery

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The deployment mechanism incorporates feedback features that provide tactile or visual confirmation of suture penetration, mesh capture, and tissue attachment status. The release features and lateral side geometry provide feedback on the deployment progress, allowing the surgeon to precisely control the suture placement and attachment process

Inventive Principle:

Principle #23Feedback

AI summary

A method of side-suturing a prosthetic to human tissue is disclosed. The method includes accessing a surgical site on a body portion of a patient; identifying the human tissue within the surgical site; endomechanically positioning the prosthetic adjacent the human tissue within the surgical site; aligning a surgical tool proximate the tissue with the prosthetic between the tool and the tissue, the surgical tool having an elongated member with distal and proximal ends; actuating the surgical tool in-situ to drive deployment members of the surgical tool outwardly away from the surgical tool, through the prosthetic and into the tissue; and retracting the deployment members back into the surgical tool, whereby the deployment members deploy a fastener to fixatedly suspend the prosthetic to the human tissue.
