Rotatable Suture Passer Guide for Endoscopic Wound Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current suture passer guides require time-consuming and tissue-damaging maneuvers to position sutures within surgical cavities, especially after endoscopic port removal, leading to inefficiencies and potential tissue damage during wound repair procedures.
Innovation Solution
A suture passer guide with a rotatable suture positioning member that extends radially from an elongate member, allowing the suture to be repositioned from one side to another without significant tilting, and an expandable member for stabilization within the surgical cavity, facilitating easier suture placement and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional suture passer guides are used after endoscopic port removal, then suture placement can be achieved, but time-consuming and tissue-damaging maneuvers are required to position sutures
Solution Approach 1:
The suture positioning member is designed to be rotatable relative to the elongate member, allowing dynamic adjustment of suture position from a first side area to a second side area. This rotational capability eliminates the need for time-consuming tilting maneuvers and enables efficient suture repositioning within the surgical cavity.
Solution Approach 2:
The suture positioning member extends radially from the elongate member, providing access to sutures in a radial dimension rather than requiring axial tilting. This dimensional change allows the distal end to reach sutures positioned laterally within the surgical cavity, significantly reducing procedural time.
2Ease of operation
If traditional suture passer guides are used after endoscopic port removal, then suture placement can be achieved, but tissue damage occurs during the positioning maneuvers
Solution Approach 1:
The rotatable suture positioning member provides dynamic positioning capability without requiring forceful tilting or probing maneuvers. The rotation mechanism allows smooth, controlled movement to reposition sutures, minimizing mechanical stress and damage to surrounding tissues.
Solution Approach 2:
The suture positioning member acts as an intermediary tool between the surgeon and the suture within the surgical cavity. It provides a controlled mechanism for suture manipulation that eliminates the need for direct, potentially damaging manual maneuvers in the tissue.
3Productivity
If the suture passer guide is inserted after endoscopic port removal, then wound repair can proceed, but surgical cavity pressure may be lost requiring re-insufflation
Solution Approach 1:
The suture passer guide is inserted into the endoscopic port before removal, maintaining the sealed state of the surgical cavity. This preliminary positioning allows the endoscopic port to be removed while the guide remains in place, preventing pressure loss and eliminating the need for re-insufflation during the wound repair process.

AI summary
This disclosure relates to suture passer guides and related kits and methods. In certain aspects, a suture passer guide includes an elongate member and a suture positioning member that can be radially extended from a distal end region of the elongate member and rotated relative to the elongate member such that the suture positioning member can reposition a suture from a first side area of the elongate member to a second side area of the elongate member.
