Adjustable Skin Wound Closure Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skin wound closure devices face challenges in adjusting stitching force randomly, making it difficult for doctors to manage wound drainage, breathability, and dressing changes, while also hindering observation of wound healing and causing inconvenience due to closed surfaces.
Innovation Solution
A skin wound closure device with a support structure and a locking device comprising a locking bar and buckle, where the locking member allows for adjustable stitching force by moving the support structure closer or further from the wound, enabling loose fitting and locking of the locking bar, facilitating breathability and direct observation of wound healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a ratchet wheel mechanism is used to increase stitching force, then the stitching force can be increased without doubt, but the stitching force cannot be randomly adjusted to increase or decrease as needed during wound stitching and healing
Solution Approach 1:
The locking member is designed to be movable relative to the locking bar, transitioning between locked and unlocked positions. This dynamic mechanism allows the stitching force to be adjusted randomly in either direction (increased or decreased) by moving the locking member, rather than being fixed in a single adjustment direction like a ratchet wheel.
Solution Approach 2:
Instead of using a ratchet wheel that only allows force increase in one direction, the invention inverts the approach by allowing the locking member to move in multiple directions. The locking member can be pushed into the locking bar to increase force, or pulled out to decrease force, providing bidirectional adjustment capability.
2Reliability
If whole wound closure is used, then skin wound edges can be closed, but it is difficult for doctors to operate and check for flat face-to-face closure of skin wound edges
Solution Approach 1:
The wound closure device is divided into multiple independent locking units, each capable of being adjusted and locked separately. This segmentation allows doctors to operate and check each locking unit individually for proper face-to-face closure, making it easier to verify the quality of closure without having to manipulate the entire wound closure system at once.
Solution Approach 2:
The locking members can be dynamically adjusted and locked in different positions, allowing the device to transition between open and closed states. This dynamic capability enables doctors to easily operate the device for closure and then adjust it to an open state for checking and observation, providing operational flexibility.
3Reliability
If whole wound closure is used, then skin wound edges can be closed, but wound healing situations cannot be observed
Solution Approach 1:
The device divides the wound closure into separate locking units with visible locking members that can be individually adjusted and locked. This segmentation creates visible indicators of the closure state and allows direct observation of healing situations at each segment, making wound healing detection easier compared to a fully closed whole wound closure system.
Solution Approach 2:
Instead of maintaining a fully closed wound surface that hides healing progress, the invention allows the locking members to be positioned in ways that maintain closure while providing visual access to healing situations. The locking members can be adjusted to provide both closure and observation capabilities simultaneously.
4Reliability
If whole wound closure is used, then skin wound edges can be closed, but it is very inconvenient for wound breathability and discharge of wound drainage
Solution Approach 1:
The wound closure is divided into multiple independent locking units with spaces between them, allowing air and fluid passage. This segmentation maintains closure of the wound edges while creating channels for breathability and wound drainage discharge, eliminating the need for separate drainage systems.
Solution Approach 2:
The locking members can be dynamically adjusted to maintain closure while allowing for breathability and drainage. The dynamic positioning of locking members enables the system to adapt between complete closure and partial openness to facilitate air and fluid passage, improving convenience for wound care.
5Reliability
If whole wound closure is used, then skin wound edges can be closed, but requirements for wound cleaning and dressing change cannot be met
Solution Approach 1:
The device divides the wound closure into separate locking units that can be independently accessed and adjusted. This segmentation allows medical personnel to clean and change dressings at each segment without compromising the overall closure, meeting the requirements for regular wound care while maintaining closure integrity.
Solution Approach 2:
The locking members can be dynamically adjusted and relocked after cleaning and dressing changes, allowing the system to adapt to different wound care requirements. The dynamic capability enables the device to maintain closure during healing while allowing access for cleaning and dressing changes when needed.

AI summary
The invention discloses a skin wound closure device capable of promoting skin wound healing and characterized by being capable of randomly adjusting stitching force for a wound. The skin wound closure device includes a support structure respectively arranged at both sides of a skin wound, at least one locking device is arranged above the support structure, the locking device includes a locking bar and a locking buckle arranged on the support structure, the locking bar is movably connected within the locking buckle, and a locking member is arranged on the locking buckle and can lock or loosely fit the locking bar in the locking buckle. Arrangement of the locking member allows doctors to loosely fit the locking bar in the locking buckle by controlling the locking member, randomly move the support structure and the locking device towards the direction close to the skin wound or the direction away from the skin wound, and lock the locking bar in the locking buckle by the locking member after proper movement, thus achieving the purpose of randomly adjusting the stitching force for the skin wound. The skin wound closure device is suitable for widespread application to healing treatment of skin wounds.
