Innovation Solution
A multifunctional compound light penetration enhanced imaging system that uses a combination of white light and red light for simultaneous illumination, with an algorithm for image synthesis, and a modular baffle plate design to adapt to different surgical modes, while maintaining minimal image processing complexity and preserving imaging speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If narrow-band imaging technique is used with special camera device and image synthesis, then image contrast enhancement is achieved, but imaging time increases and imaging speed decreases
Solution Approach 1:
The patent uses simultaneous illumination with multiple light sources (white light and red light) to achieve continuous imaging without time-sharing, eliminating the need for sequential illumination and image synthesis while maintaining enhanced image contrast and penetration through blood
2Adaptability or versatility
If multiple endoscopic sheaths are used for different surgical procedures, then adaptability to different surgical modes is improved, but device complexity and cost increase
Solution Approach 1:
The patent designs a single endoscopic sheath that can perform multiple functions by integrating different working baffle plates (single-function and multi-function) that can be selectively installed, allowing the same sheath to adapt to various surgical procedures including spinal endoscopic surgery and transforaminal endoscopic surgery
Solution Approach 2:
The patent incorporates adjustable working baffle plates that can be dynamically configured or replaced based on surgical needs, enabling the system to adapt its functionality during different surgical procedures without requiring multiple fixed sheaths
3Ease of manufacture
If single-function working baffle plate with certain size is used, then ease of manufacture is improved, but adaptability to different surgical operations decreases
Solution Approach 1:
The patent divides the working baffle plate into separate, interchangeable components (single-function baffle plate and multi-function baffle plate) that can be manufactured independently and then assembled or replaced based on specific surgical requirements, simplifying manufacturing while enhancing adaptability
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 system achieves enhanced imaging without sacrificing speed, simplifies image processing, and adapts to various surgical procedures by adding a red light component to white light for improved penetration through blood, ensuring clear images with minimal light loss and reduced wound size for different surgical applications.
Implementation Method 1
the fluid mixed with the blood appears red, with the minimum absorption for red light and the maximum absorption for other colors such as blue light; at this moment, the red light component penetrates through the fluid mixed with the blood, irradiates onto the tissue

AI summary
The present invention belongs to the technical field of medical instruments, and discloses a multifunctional compound light penetration enhanced imaging system and an enhanced imaging method. The structural design of the present invention is reasonable. Through the cooperation of the first working channel tube, the second working channel tube, and the third working channel tube, the size of the channel is switched. When the system shrinks to the minimum, the opening size of the wound is only ⅓ of that when the system is fully opened, which is suitable for a double-channel spinal endoscopic surgery. When the system is expanded to the maximum, it is suitable for transforaminal endoscopic surgery, and is suitable for multiple surgical modes. By adding a special red light component on the basis of the white light to form compound light illumination and increase the system transmittivity, the background penetration is realized.
