Self-Expanding Spatial Structure for Endoscopic Tissue Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic surgeries, existing methods often damage non-target body tissues and require multiple grasping forceps, increasing invasiveness and operator burden, as they struggle to effectively support tissues and maintain a clear operative field without enlarging the body cavity.
Innovation Solution
A deformable spatial structure that can be shrunk for insertion and enlarged within the body cavity to support tissues, allowing for the insertion of endoscopes and treatment instruments to target lesions while minimizing invasiveness and operator burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple grasping forceps are used to move non-target tissues, then tissue displacement is achieved, but the number of holes required increases and invasiveness increases
Solution Approach 1:
The patent combines multiple functions (tissue support, displacement, and operative field creation) into a single self-expanding spatial structure. This structure can be inserted through one hole and performs multiple functions simultaneously, eliminating the need for multiple separate grasping forceps and multiple insertion holes, thus reducing invasiveness while maintaining operational capability.
Solution Approach 2:
The spatial structure serves multiple purposes: it supports non-target tissues, creates operative field space, and enables instrument insertion. This multi-functional design replaces the need for multiple specialized tools (multiple grasping forceps), reducing the number of holes required and overall invasiveness while maintaining ease of operation.
2Ease of operation
If multiple grasping forceps are used to move non-target tissues, then tissue displacement is achieved, but operator burden increases
Solution Approach 1:
The patent merges the functions of multiple grasping forceps into a single spatial structure that automatically performs tissue displacement and support. This reduces the number of instruments the operator must manage, thereby reducing operator burden while maintaining the same tissue manipulation capability.
Solution Approach 2:
The spatial structure is self-expanding and self-positioning, eliminating the need for multiple manually operated grasping forceps. The structure automatically creates the operative field and supports tissues without requiring continuous manual intervention with multiple instruments, thus reducing operator burden and simplifying the procedure.
3Ease of operation
If the body cavity is enlarged to create operative field, then observation and treatment access is improved, but tissue damage to non-target organs increases
Solution Approach 1:
The spatial structure provides localized support to specific non-target tissues that need to be displaced, rather than requiring global enlargement of the entire body cavity. This targeted approach creates the necessary operative field access while minimizing unnecessary tissue manipulation and damage to organs not requiring displacement.
Solution Approach 2:
The self-expanding spatial structure automatically creates the operative field and positions tissues without requiring manual manipulation with multiple instruments. This automated process reduces the risk of tissue damage by eliminating repeated insertion and manipulation of grasping forceps, while still achieving the necessary field access for observation and treatment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The spatial structure effectively supports tissues, creates necessary space for observation and treatment, reduces invasiveness, and simplifies procedures by allowing self-enlargement without external operation, thereby minimizing tissue damage and operator burden.

AI summary
A minimally invasive endoscopic surgical procedure or an endoscopic surgical procedure through natural orifices which includes: introducing a spacial structure in a shrunken state into a body cavity by a spacial structure introduction portion; enlarging the spacial structure in the body cavity; setting the enlarged spacial structure in a predetermined position in the body cavity and supporting the tissues inside of the body cavity with the set spacial structure; inserting a distal end of at least an endoscope or a treatment instrument from at least a part of an opening portion of the spacial structure, and orienting the distal end to a pathological lesion located on the inner side of the tissues inside of the body cavity which is supported by the spacial structure.
