Coiled Nerve Tissue Wrap for Suture-Free Lesion Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for treating nerve and tendon lesions, such as suturing and additional wrapping, are cumbersome, anatomically challenging, and complicate surgical procedures, often leading to improper closure and increased tissue damage.
Innovation Solution
A medical tissue wrap with a coiled wall design featuring a circumferential inner and outer end portion with a discontinuous radial spacing and structural outer surface modifications, allowing for secure closure and retention of the anatomical structure without sutures, facilitating easy application and reducing tissue growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional suturing techniques are used to coapt nerve ends, then nerve connection is achieved, but surgical complexity and tissue damage increase
Solution Approach 1:
The invention extracts and eliminates the need for sutures and complex coaptation techniques by using a simple elastic bandage wrap that mechanically secures the nerve ends together through elastic retraction, achieving nerve connection without traditional surgical complexity
Solution Approach 2:
The elastic bandage wrap performs the nerve coaptation function autonomously through its elastic properties, automatically securing the nerve ends together without requiring complex surgical techniques or additional materials like sutures
2Reliability
If additional wrapping or multiple layers are applied to ensure closure, then closure reliability improves, but ease of operation deteriorates
Solution Approach 1:
The elastic bandage is segmented into multiple loops that can be independently applied around the nerve, with each loop providing a portion of the closure function, allowing reliable closure to be achieved through simple repeated applications rather than complex single-step procedures
Solution Approach 2:
The elastic bandage utilizes dynamic elastic retraction properties to automatically adjust and secure the nerve ends together, providing reliable closure through the material's inherent elasticity rather than requiring rigid, complex structural constraints
3Stability of the object's composition
If the medical tissue wrap uses continuous wall structure, then structural stability improves, but ease of operation deteriorates due to difficulty in insertion
Solution Approach 1:
The continuous elastic bandage is segmented into discrete loops that can be individually applied around the nerve, allowing the structure to maintain continuity and stability while being easy to apply through simple loop placement rather than complex insertion
Solution Approach 2:
The elastic bandage transitions from a potential single continuous structure to multiple discrete loops arranged in a longitudinal sequence, allowing the wrap to be applied by simply placing loops around the nerve in sequence, which is operationally simpler while maintaining structural integrity

AI summary
The invention relates to the field of medical tissue wraps for internal anatomical structures as well as a use and a method of treating a nerve lesion using such medical tissue wraps. In particular, the invention relates to medical tissue wraps for neural tissue supporting the repair of peripheral nerve lesions by facilitating secure application of the medical tissue wrap. Accordingly, a medical tissue wrap (10) for an internal anatomical structure of a mammal is suggested, wherein the medical tissue wrap (10) is formed by a coiled wall (12) having a circumferential inner end portion (20) and a circumferential outer end portion (22) extending around and overlapping the circumferential inner end portion (20). The wall (12) thereby defines a longitudinal through-hole (16) for accommodating a portion of the anatomical structure. According to one aspect of the invention, the circumferential outer end portion (22) is radially spaced-apart from the circumferential inner end portion (20) by a discontinuous spacing in the circumferential direction. According to a further aspect, the tissue wrap comprises a structural outer surface modification at opposing longitudinal end portions of its wall.
