Surgical Suturing Device Pre-Knotted Suture Continuous Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical suturing methods, particularly those using pre-knotted endoloops, require users to repeatedly release and re-grasp the target area, which can be problematic, especially when dealing with sensitive areas like bleeding vessels, as they often necessitate opening and closing the loop around the application site.
Innovation Solution
A surgical suturing device comprising a handle, grasping mechanism, first and second jaws, and couplers that allow for the application of an open-loop, pre-knotted suture to be closed around a target area without requiring the user to release their hold, utilizing a mechanism where the suture can be passed through the device to form a closed loop and tied off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional endoloops are used for suturing, then the suture can be applied around the target area, but the user must repeatedly release and re-grasp the target area which increases operational complexity and time
Solution Approach 1:
The suture is pre-knotted and prepared in advance with the knot already formed, eliminating the need for the user to perform knot-tying actions during the procedure. The pre-knotted configuration allows the suture to be directly applied around the target area without requiring repeated manipulation and re-grasping actions.
Solution Approach 2:
The device serves as an intermediary mechanism that facilitates the passage of the pre-knotted suture around the target area. The device's structure enables the suture to be looped and secured without requiring the user's hand to repeatedly grasp and release the target area, thereby reducing operational time and complexity.
2Adaptability or versatility
If the user repeatedly releases and re-grasps the target area to apply the endoloop, then the suture can be positioned, but this increases the risk of complications to delicate tissues
Solution Approach 1:
By preparing the suture in advance with the knot already formed, the procedure eliminates the need for repeated grasping and releasing actions that could damage delicate tissues. The pre-knotted configuration allows for a single, controlled application around the target area, reducing the risk of tissue trauma while maintaining adaptability to different tissue types.
3Reliability
If a closed-loop endoloop is used, then the suture can be tied off, but the user cannot maintain continuous control over the target area during application
Solution Approach 1:
The suture is pre-knotted and prepared in advance, which allows the user to maintain continuous control over the target area during application. The pre-formed knot eliminates the need for repeated grasping and releasing actions, enabling the user to keep their hand on the target area throughout the entire procedure and ensure reliable placement.

AI summary
The present invention is a surgical suturing device that assists in applying an open-looped, pre-knotted suture around a targeted area of application. The surgical suturing device contains a handle, a grasping mechanism, a first jaw, a second jaw, a first coupler, and a second coupler. The first jaw and the second jaw each contains a jaw body and a coupler receiver. The first coupler and the second coupler each contains a strand receiver. The handle is operatively connected to the first jaw and the second jaw through the grasping mechanism. The coupler receiver is positioned adjacent to the jaw body, opposite to the grasping mechanism along the jaw body. The first coupler is removably positioned within the coupler receiver of the first jaw. The strand receiver traverses into the first coupler and the second coupler. The second coupler is removably positioned within the coupler receiver of the second jaw.
