Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If laser fiber is used for laparoscopic surgery, then cutting and hemostatic effects are improved, but control difficulty increases requiring multiple incisions and assistants
Solution Approach 1:
The patent integrates multiple functions (cutting, flushing, suction) into a single laser fiber operator device. The operator includes a laser fiber channel, flushing liquid injection channel, and smoke suction channel all combined in one instrument, allowing single-handed operation without requiring multiple incisions or assistants.
Solution Approach 2:
The laser fiber operator is designed as a multi-functional device that can perform cutting, continuous flushing, cooling, and smoke suction operations simultaneously or sequentially through integrated channels and valves, making it a universal tool for laser-assisted laparoscopic surgery.
2Temperature
If continuous flushing is performed to cool laser fiber, then eschar formation is reduced, but surgical field vision is blurred
Solution Approach 1:
The patent enables continuous flushing action through the integrated flushing liquid injection channel that runs along the laser fiber, maintaining continuous cooling to prevent eschar formation while the suction channel simultaneously removes excess fluid to maintain surgical field visibility.
Solution Approach 2:
The patent introduces smoke suction as an intermediary function that removes excess flushing liquid and smoke from the surgical field, allowing continuous flushing to occur without blurring the surgical vision. The suction channel acts as a mediator between the flushing system and the visual field.
3Object-generated harmful factors
If smoke suction is performed with pneumoperitoneum, then smoke is removed, but air leakage causes pressure instability
Solution Approach 1:
The patent extracts smoke and excess fluid from the surgical field through a dedicated suction channel that is integrated into the laser fiber operator. This allows selective removal of harmful substances without requiring separate suction incisions, and the system can be designed to minimize air intake during suction.
Solution Approach 2:
The laser fiber operator performs self-service by integrating suction and flushing functions directly into the cutting instrument, allowing the surgeon to control all functions (cutting, flushing, suction) through a single device without requiring separate assistants or instruments, thereby maintaining pneumoperitoneum stability.
4Temperature
If multiple incisions are made for flushing and suction, then cooling and smoke removal are improved, but patient injury and costs increase
Solution Approach 1:
The patent merges flushing liquid injection and smoke suction functions into a single integrated operator device that enters through one incision. The device includes a laser fiber channel, flushing liquid injection channel, and smoke suction channel all combined in one instrument, eliminating the need for multiple separate incisions.
Solution Approach 2:
The laser fiber operator serves multiple functions (cutting, flushing, cooling, suction) through a single multi-functional device, reducing the number of incisions required and minimizing patient trauma while maintaining effective cooling and smoke removal capabilities.
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
Enhances surgical efficiency and safety by ensuring stable pneumoperitoneum pressure, clear vision, and reduced patient injury and costs through integrated operation of cutting, flushing, and suction functions.
Implementation Method 1
Because of high efficiency, accuracy and good cutting and hemostatic effects, laser may not only be used to remove skin on the body surface, lumps, etc.
Implementation Method 2
Due to high energy of laser fibers, continuous cooling with water is required during a surgery to reduce the formation of eschar on a wound.
Implementation Method 3
laser fibers may also produce a lot of smoke when cutting organs or human tissues, so an operation field of view is blurred and smoke needs to be discharged in time

AI summary
The present invention provides a laser fiber operator. The laser fiber operator includes a first pipe sleeve for mounting, and the first pipe sleeve is provided with a front passage for threading of an optical fiber in an axially through manner. Moreover, a first guide pipe, a second guide pipe, and a third guide pipe are axially mounted at a front end of the first pipe sleeve, and flow guide passages are formed between the guide pipes. Similarly, a second pipe sleeve and a third pipe sleeve are coaxially mounted at a rear end of the first pipe sleeve, and a flow guide passage is also formed between the second pipe sleeve and the third pipe sleeve. As the passages at the front end and the rear end of the first pipe sleeve are correspondingly connected and independently provided, effects of suction drainage and flushing drainage can be achieved according to requirements of use. Moreover, valves are disposed on the corresponding passages to achieve control over suction and flushing. An incision is rapidly and accurately flushed and cooled during cutting of a laser surgery, a field of view can be improved, and surgical efficiency and safety are improved. In addition, cutting, flushing and suction functions are integrated, and a surgeon can achieve the above operations with one hand, and usage is more convenient.
