Endoscope Cable Guide Member for Single-Handed Visual Field Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic surgery efficiency is hindered by the need for surgeons to release their hands from treatment tools to adjust the endoscope's visual field, requiring assistance and prolonging surgery time.
Innovation Solution
A treatment tool with a guide member that allows the endoscope's cable to be moved forward and backward using a finger, enabling the surgeon to change the visual field without releasing their hands, combined with an interlocking member inside the overtube for coordinated movement of the endoscope and treatment tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the surgeon releases hands from the treatment tool to adjust the endoscope's visual field, then the visual field can be changed, but the surgeon's hands are occupied and surgery time is prolonged
Solution Approach 1:
The patent combines the endoscope and treatment tool into a single integrated unit, allowing the surgeon to control both the treatment tool and endoscope visual field adjustment with one hand. The endoscope is positioned to allow finger access for visual field adjustment while the surgeon maintains grip on the treatment tool, merging two separate control functions into one unified device.
Solution Approach 2:
The endoscope is designed to be self-adjustable by the surgeon's finger without requiring assistance from an endoscopic technician. The visual field can be adjusted directly by the surgeon's finger contact with the endoscope, enabling the surgeon to perform self-service visual field adjustment while maintaining control of the treatment tool.
2Ease of operation
If an assistant operates the endoscope based on surgeon's instructions, then the surgeon can focus on treatment tool operation, but the operation becomes complicated and surgery time is prolonged
Solution Approach 1:
The patent merges the control functions of the endoscope and treatment tool into a single integrated unit. The endoscope is positioned and designed to allow the surgeon to adjust the visual field directly with their finger while maintaining grip on the treatment tool, eliminating the need for separate assistant coordination and simplifying the overall operation.
Solution Approach 2:
The endoscope is designed to be self-adjustable by the surgeon without requiring an assistant. The surgeon can directly manipulate the endoscope's visual field using their finger, making the system self-sufficient and eliminating the complexity of coordinating between surgeon and assistant operations.
3Adaptability or versatility
If multiple holes are made in the patient's body wall for separate endoscope and treatment tool insertion, then each tool can be inserted independently, but the invasion to the patient increases
Solution Approach 1:
The patent combines the endoscope and treatment tool into a single integrated insertion unit. Both the endoscope and treatment tool are inserted through a single hole in the patient's body wall, reducing the number of punctures required while maintaining the functional independence and versatility of both tools through their integrated design.

AI summary
Provided are an endoscopic surgical device, a treatment tool, and a guide member capable of performing change to a visual field suitable for detailed observation and treatment with a simple operation, and improve surgical efficiency. An endoscope insertion part 102 of an endoscope and a treatment tool insertion part 202 of a treatment tool are insertable through an overtube 300 inserted into a body wall, and a slider is provided for moving the endoscope insertion part 102 and the treatment tool insertion part 202 forward and backward in an interlocking manner. An operating part 204 of the treatment tool inserted through the overtube 300 is provided with a guide member 230 that guides a cable part 104 so as to be movable forward and backward in an axial direction so that the cable part 104 of the endoscope 100 is kept from being separated from the surface of the operating part 300 beyond a fixed distance. Accordingly, the cable part 104 can be reliably held down by an index finger of a right hand gripping the operating part 204 of the treatment tool, and, the operation of the operating part 204 and the forward and backward movement operation of the endoscope insertion part 102 can be performed with only a right hand.
