The independent cooler control system for the laser scalpel has high power, supports independent coolers with various cooling modes, assists the laser scalpel in cooling, enables the surgical effect to be optimal, and promotes the laser scalpel to be clinically applied. The problem of laser surgery cooler cooling power low, the cooling effect is not good is solved.
The cooling requirements of different types of operations on the laser cutter head can be met, and the independent cooler is simple and convenient to operate, high in cooling speed and stable and reliable in working on the premise of meeting the cooling temperature.
The working principle is shown in figure 1:
an independent cooler is designed on the basis of a built logic control circuit and a built gas circuit by adopting an electronic refrigeration technology. The chiller is designed to support three modes of operation: electronic semiconductor refrigeration, air refrigeration and carbon dioxide refrigeration. Different working modes can be selected according to different operation types. The switching between the modes is realized by a logic circuit, can be completed by one key, and is simple and convenient to operate. The gas flow and the pressure can be adjusted, and the current gas flow, the current pressure and the current temperature can be observed in real time through the digital display module.
The invention mainly comprises an air compression pump, a semiconductor cooling module, an electric control system, an air path and a pneumatic element. An air compressor pump provides a source of compressed gas for air cooling and electronic cooling. The compressed gas has a certain flow velocity in the rear-stage gas circuit, and the heat of the cutter head can be quickly taken away by the flowing gas, so that the purpose of cooling is achieved. The semiconductor cooling module mainly comprises an electronic refrigeration piece and a fan cooling module, and is a core component of electronic refrigeration. When gas flows through the copper coil pipe in the electronic refrigeration cavity, the gas is rapidly cooled, and the heat of the tool bit can be rapidly taken away by the cooled flowing gas. The gas circuit and the pneumatic element realize the switching of different cooling modes, gas source selection and gas flow direction control under the coordination of an electric control system. The electric control system comprises a power switch, a power filter, a switch power supply, a logic control circuit, a digital display module and the like. Mode switch button, digital display module, flow control knob and pressure adjustment knob overall arrangement are on the front panel, convenient operation and observation.
In the present invention, an air compressor pump is used to provide a compressed air source for the cooling gas. When the laser cutter head works in an air cooling mode, compressed air is conveyed to the rear stage for cooling the laser cutter head through flow and flow rate regulation. When the laser tool bit works in the electronic refrigeration mode, compressed air is cooled by the electronic refrigeration piece and then is used for cooling the laser tool bit. When the cooling device works in a carbon dioxide cooling mode, an external carbon dioxide gas source is used for providing a carbon dioxide gas source for the independent cooler. And the carbon dioxide gas is conveyed to the rear stage for cooling the laser tool bit after the flow and the pressure are adjusted.
In the invention, noise generated by the air compression pump during operation is reduced. The design of the secondary damping structure and the arrangement of the silencer at the inlet of the air compression pump well solve the noise problem of the air compression pump.
In the invention, in order to improve the refrigeration efficiency of the whole machine, an air duct and a shell heat dissipation system are designed according to the internal structure and the layout.
As shown in FIG. 2, the present invention designs a simple and easy-to-use operation panel, which is convenient for the user to select the operation mode and adjust the gas pressure and flow rate according to the requirement. The operation panel is arranged on the front side of the cooler shell and consists of a power switch, a work starting key, an indicator light, a gas flow regulating valve, a carbon dioxide pressure regulating valve, a gas flow digital display, a carbon dioxide pressure digital display, a gas temperature digital display and a luer connector.
The invention has the main advantages that:
1. the cooling power is large: a high-power supply, an air compression pump and an electronic refrigerating sheet are adopted, so that the laser cutter head with the maximum weight of 25W can be cooled; 2. three cooling modes are supported: the air refrigeration mode, the electronic refrigeration mode and the carbon dioxide refrigeration mode can meet most of operation requirements.
The specific embodiment is as follows:
the cooler is used in cooperation with the laser scalpel and used for cooling the scalpel head. When in use, the laser scalpel main machine and the laser scalpel main machine are arranged on the same trolley. When the operation is prepared, after the cooler is successfully electrified by operating the power switch by an operator, the cooler enters a ready state, and different cooling working modes can be selected for cooling according to the type of the operation.
A carbon dioxide refrigeration mode: and pressing a carbon dioxide selection key under the condition of ensuring that other refrigeration modes are closed, wherein a corresponding carbon dioxide indicator lamp is turned on, and the carbon dioxide refrigeration mode is selected and started. At this time, the pressure and flow rate of the carbon dioxide gas can be adjusted.
An electronic refrigeration mode: and when the electronic refrigeration selection key is pressed under the condition that other refrigeration modes are ensured to be closed, the corresponding electronic refrigeration indicator lamp is turned on, and the electronic refrigeration mode is selected and started. The electronic refrigeration mode is started and then precooled for about 20 minutes, and cold air starts to be output after the precooling time is over, so that the electronic refrigeration mode can be normally used, and the gas flow can be adjusted. Therefore, when the electronic cooling mode is used, the electronic cooling mode should be started in advance. After the use is finished, the electronic refrigeration selection button is pressed, the electronic refrigeration working mode is stopped, air is still output, and the time is about 20 minutes. During the period, the power supply is not cut off, and the power supply is turned off after the digital flow display shows zero. If the power is turned off in advance, the operation of the cooler may be abnormal.
An air cooling mode: and when the air cooling selection key is pressed under the condition that other cooling modes are ensured to be closed, the corresponding air cooling indicator lamp is turned on, and the air cooling mode is selected and started. At this time, the air flow rate may be adjusted as needed.
The invention has the beneficial effects that:

Adopt the electron refrigeration piece, can cool off the air fast, provide the air cooling source of lower temperature. And the flow regulating valve is adopted to regulate the gas flow.
2. Support three cooling modes
In order to meet different surgical occasions, three cooling modes are designed: air refrigeration, electronic refrigeration, and carbon dioxide refrigeration. The user can select different cooling modes according to the needs. The air refrigeration adopts a mode of compressing normal temperature air, and directly acts on the laser surgical knife head after flow regulation for cooling the surgical knife head; the electronic refrigeration cools the normal temperature gas through the electronic refrigeration piece, and the cooled gas acts on the laser surgical knife head through compression and flow regulation and is used for cooling the surgical knife head. The carbon dioxide refrigeration mode adopts an external carbon dioxide gas source, and the gas source acts on the laser surgical knife head after pressure regulation and flow regulation and is used for cooling the surgical knife head.
3. Low noise
