Endoscopic Anchor Member for Organ Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic surgical procedures face challenges in manipulating and stabilizing endoscopic devices and body organs due to the distance between the distal and proximal ends of the endoscope and the consistency of large, dense organs, which complicates surgical procedures.
Innovation Solution
The development of anchor members that can be endoscopically implanted in the internal wall of a body cavity to create an opening for anchoring endoscopic devices or support members, allowing for the manipulation of organs by sliding the device relative to the anchor member, with various configurations such as hoops, elongate rods, and sutures for tissue engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the endoscope is used to access the peritoneal cavity through a natural body orifice or small incision, then the invasiveness is reduced and recovery time is shortened, but the ability to manipulate and stabilize organs is compromised due to the distance between distal and proximal ends
Solution Approach 1:
The patent introduces an anchor member as an intermediary device that is implanted in the body cavity wall to provide a stable reference point. This anchor member acts as a mediator between the endoscope and the organs, enabling the surgeon to manipulate and stabilize organs by sliding the endoscope relative to the anchored position, thereby resolving the contradiction between minimally invasive access and the ability to manipulate organs.
2Object-affected harmful factors
If the endoscope is inserted through a natural body orifice or small incision, then the surgical approach is less invasive, but the consistency and density of large organs makes manipulation difficult
Solution Approach 1:
The anchor member is implanted and anchored to the body cavity wall before the surgical manipulation of organs begins. This preliminary action establishes a stable reference framework that enables subsequent manipulation of dense organs by providing an external anchor point, allowing the surgeon to control organ position without increasing surgical trauma.
3Volume of moving object
If the distal end of the endoscope is located inside the body far from the proximal end, then access to deep surgical sites is achieved, but control and stabilization of the device becomes difficult
Solution Approach 1:
The anchor member serves as an intermediary reference point that is fixed in the body cavity wall. By anchoring the endoscope to this stable reference point, the surgeon can maintain control and stabilization of the distal end even when it is positioned deep within the body cavity, resolving the contradiction between reach depth and control capability.

AI summary
Various exemplary methods and devices are provided for manipulating and/or anchoring devices and body parts during surgical procedures. In one embodiment, an anchor member is provided for anchoring a device or body part to tissue, such as an internal wall of a body cavity. The device can be, for example, an endoscopic device, an accessory channel coupled to an endoscopic device, or a support member adapted to support or manipulate an organ. The anchor member can include or form an opening through which the device can be inserted. The anchor member or device can thus be manipulated relative to the tissue to control movement of and/or provide support to the device, tools inserted through the device, and/or organs grasped by the device or tools.
