Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If laser probes are used for cutting and ablation, then surgical efficiency is improved, but healthy tissues are damaged due to over-high temperature
Solution Approach 1:
The patent changes the temperature parameter from high (laser) to low (plasma), achieving effective cutting and ablation at lower temperatures that do not damage healthy surrounding tissues. The plasma generator operates at temperatures sufficient for tissue separation but below the threshold for thermal damage to adjacent healthy tissue.
Solution Approach 2:
The patent replaces the thermal-mechanical laser system with a plasma-based system that uses ionized gas reactions rather than direct thermal heating. This substitution of the underlying physical mechanism allows for cutting and ablation without the excessive heat generation characteristic of laser probes.
2Productivity
If laser probes are used for cutting and ablation, then surgical efficiency is improved, but smoke is produced due to volatilization
Solution Approach 1:
The patent changes the temperature parameter from high (laser) to low (plasma), preventing the volatilization of solid and liquid materials that causes smoke production. The lower operating temperature of plasma maintains tissues in a non-volatile state, eliminating smoke generation while preserving cutting effectiveness.
3Reliability
If auxiliary apparatus are used for hemostasis and cleaning, then surgical completeness is improved, but workload of medical staff increases
Solution Approach 1:
The patent makes the plasma probe multi-functional by integrating cutting, ablation, hemostasis, and cleaning capabilities into a single device. The plasma reaction simultaneously achieves tissue separation and coagulation of blood vessels, while the irrigation system provides cleaning, eliminating the need for separate auxiliary apparatus and reducing staff workload.
Solution Approach 2:
The patent merges multiple surgical functions (cutting, ablation, hemostasis, cleaning) into a single integrated plasma probe system. By combining these previously separate functions into one device, the system reduces the number of auxiliary apparatus needed and simplifies the surgical workflow.
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 effectively reduces tissue damage and smoke production by maintaining low temperatures during surgeries, simplifies the surgical process, and reduces the workload and costs associated with hemostasis and cleaning.
Implementation Method 1
a vibration module (102), wherein the vibration module is used to vibrate the electrode
Implementation Method 2
the vibration module is used to vibrate the electrode at a vibration frequency of 20 kHz to 100 kHz
Implementation Method 3
Plasma is generated when the normal saline flows to the tool bit. Because a lot of heat is taken away when the normal saline flows, tissues are cut at low temperature to achieve low-temperature cut, hemostasis and ablation.
Implementation Method 4
tissues are cut at low temperature to achieve low-temperature cut, hemostasis and ablation

AI summary
The invention discloses a low-temperature plasma generator used in surgeries and a probe system controlled by the same. The plasma generator comprises a CPU (central processing unit) control module, a vibration module connected with the CPU control module, a low-temperature plasma generator composed of an output module which is connected with the vibration module, and a probe system, comprising normal saline input equipment and a plasma probe, controlled by the low-temperature plasma generator. By the arrangement, defects of over-high temperature and big smog during cutting in existing surgeries are overcome, and defects of serious influences on surgery process caused by the fact that auxiliary equipment is needed for cleaning after blooding are further overcome. Low-temperature cutting is realized by generating the plasma probe, and timely cleaning can also be realized. The low-temperature plasma generator applied to surgeries and the probe system controlled by the same are convenient and quick to operate and quite suitable for operations on operating tables.
