Adaptive Camera Head Cover for 2D and 3D Endoscopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical systems require separate instruments for 2D and 3D endoscopes, leading to increased hospital investment and inefficiencies in surgical procedures, as there is no single system that can adapt both 2D endoscopes of various sizes and 3D laparoscopes, necessitating longer setup times and occupying more space in the operating theater.
Innovation Solution
A surgical instrument with an adaptive element that can hold both the eyepiece of a 2D single channel endoscope and two eyepieces of a Stereo 2 channel 3D laparoscope, featuring a locking arrangement and focusing ring for secure attachment and adjustable focal length, along with a camera head cover and touchpad switch for seamless mode switching between 2D and 3D visuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate systems are used for 2D and 3D endoscopes, then each system can be optimized for its specific function, but hospital investment increases and device complexity increases
Solution Approach 1:
The camera head cover is designed with a universal adaptive element that can accommodate both 2D single channel endoscope eyepieces and stereo 2 channel 3D laparoscope eyepieces. The adaptive element includes a cavity with locking arrangements that can securely hold different types of eyepieces, allowing one camera head cover to perform multiple functions previously requiring separate systems.
Solution Approach 2:
The adaptive element incorporates a dynamic locking mechanism with plunger arrangements that can adjust and secure different eyepiece types. The locking arrangement can be engaged or disengaged to accommodate various eyepiece configurations, providing adaptability without requiring separate fixed systems for 2D and 3D operations.
2Ease of repair
If separate systems are used for 2D and 3D endoscopes, then each system can be independently maintained, but setup time increases and productivity decreases
Solution Approach 1:
The camera head cover serves as a universal platform that can quickly switch between 2D and 3D endoscope configurations. The adaptive element with its standardized cavity and locking mechanism allows rapid attachment and detachment of different eyepiece types, reducing setup time from minutes to seconds while maintaining the ability to independently maintain different endoscope systems.
3Reliability
If separate systems are used for 2D and 3D endoscopes, then equipment availability is ensured, but space requirements increase and cost increases
Solution Approach 1:
The invention merges the previously separate 2D and 3D endoscope systems into a single unified camera head cover. The adaptive element combines multiple eyepiece accommodation capabilities within one structure, reducing the number of separate equipment pieces needed in the operating theatre while ensuring both 2D and 3D functionalities remain available.
Solution Approach 2:
The universal camera head cover eliminates the need for multiple dedicated systems by providing a single platform that can accommodate both 2D single channel and 3D stereo eyepieces. This reduces the space required in the operating theatre while maintaining equipment availability for both surgical modalities.
4Reliability
If separate systems are used for 2D and 3D endoscopes, then system specialization is achieved, but hospital investment increases
Solution Approach 1:
The adaptive element with its standardized cavity and locking mechanism creates a universal interface that maintains system specialization benefits while reducing the need for duplicate investments. Hospitals can invest in one camera head cover system that supports both 2D and 3D operations, eliminating the need to purchase and maintain separate systems for each modality.

AI summary
The present invention is to provide a surgical instrument for performing an endoscopy or a laparoscopy. The surgical instrument includes an adaptive element capable of holding an eyepiece of a 2D single channel endoscope and two eyepieces of a Stereo 2 channel 3D laparoscope. The adaptive element is arranged on a camera head cover of the surgical instrument. Further, the adaptive element is a holder having a cavity which allows the eyepieces of the 2D endoscope or Stereo 2 channel 3D laparoscope to fit positively therewith.
