Laparoscope Rotation Assist with Light-Guide Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laparoscopes require two-handed manipulation or assistance for rotation, which can prolong surgeries, introduce miscommunication risks, and pose safety hazards due to light-guide cable disconnections.
Innovation Solution
A rotational assistance device that attaches to a laparoscope, allowing single-handed rotation by extending from the instrument and securing the light-guide cable, preventing disconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-handed manipulation is used to rotate the laparoscope, then rotation control is achieved, but surgical efficiency decreases and miscommunication risks increase
Solution Approach 1:
The device separates the rotation control function from the main instrument body by adding a独立的 extension element with interface component. This allows one hand to hold the camera while the other hand operates the extension element for rotation, resolving the contradiction between rotation control and surgical efficiency.
2Ease of operation
If two-handed manipulation is used to rotate the laparoscope, then rotation control is achieved, but safety risks increase due to light-guide cable disconnections
Solution Approach 1:
The extension element is pre-configured with the interface component and light-guide cable connection before the surgical procedure. This preliminary setup ensures that the light-guide cable remains securely connected during rotation operations, eliminating safety risks while maintaining rotation control.
3Productivity
If a rotational assistance device is added to enable single-handed rotation, then surgical efficiency improves, but device complexity increases
Solution Approach 1:
The extension element acts as an intermediary component that connects the operator's hand to the laparoscope's rotation mechanism. This simple mediator enables single-handed operation without requiring complex integrated systems, thus improving surgical efficiency while minimizing added complexity.

AI summary
A surgery system includes a surgical instrument and a rotational assistance device. The surgical instrument includes an elongated element and is configured to be connected to a laparoscopic camera. The rotational assistance device includes one or more interface components attachable to the surgical instrument. The rotational assistance device further includes an extension element extending from the one or more interface components. A force applied to the extension element can cause rotation of the elongated element of the surgical instrument relative to the laparoscopic camera of the surgical instrument.
