The technical fields used in this tool along with the relevant explanations and differences include the following elements:

• Device performance: the feeding system and control circuit of Rayin Sanat medical plastering saw is based on direct or dc power supply, but it causes the blade to move by converting electrical energy into rotary motion and then into oscillating motion. Rayin Sanat’s medical plastering saw uses a 24-volt electric power supply mechanism. Based on the need to use the maximum efficiency of the DC motor, a 10 amp power switch has been used as a converter and power source for the drive motor. The use of DC electrical systems has added good advantages and capabilities to this device, which include: easy use and the possibility of changing the speed, light weight of the device, high safety, better controllability and greater stability, reduced construction costs, high mobility for the operator.
• Strong and precise performance: Rayin Sanat plastering saw can cut plaster precisely and strongly. High performance, appropriate cutting power and reducing the risk of cuts or damage to the underlying tissues are among the functional features of this device.
• Blade: The blade of a medical plaster saw is usually made of steel or stainless steel and resistant metal alloys. The design of the blade is such that it has many sharp edges so that it can easily pass through the plaster and make a smooth and precise cut without getting stuck inside the plaster. Rayin Sanat medical plastering saw blades are made narrow (thickness less than 2 mm) and sharp (Kose tooth type) so that they can move well on the surface of the plaster. find quality, it can increase the useful life of the saw.
• Body: The body of Rayin Sanat medical plastering saw is designed and made in an ergonomic way, which is easy to hold and allows the user to have precise control. The body is made of aluminum (light weight and high strength). Also, the location of the hand on the body is designed in such a way that it allows the user to adjust the angle of the hand and the position of the device in relation to the patient’s limb.
• Power system: The power required to cut plaster in this machine is from an electric motor based on DC input power with 24 voltage. The electric motor of Rayin industrial plastering saws is a powerful motor that has passed cutting tests on wood and plasters with polyester fibers and even Teflon, and this electric motor provides the movement of the blade. This motor is activated by connecting to the output power source of the power switch, and based on the design, it provides the driving force required for the swing of the blade with maximum speed and power. Then the power output enters the power transmission mechanism unit.

The switching power converter system, which is also called the switching power supply system, is a type of electronic circuit that is used to convert and regulate voltage and electric current between power sources and loads, based on pulse width (PWM) voltage and It adjusts the current according to the needs of the device. This system is used in the feeding section of the device, which needs to be fed with its independent voltage or current by 220 volt city electricity. The used power switch converter system increases the efficiency of the device due to the reduction of energy wastage and reduces energy loss to a great extent. Also, compared to other traditional methods of providing input power, it has a smaller volume and lighter weight, which increases the overall capabilities of the device.

• Power transmission mechanism: In order to transfer rotational force to the head of the device, and also considering creating suitable conditions for repairs and future after-sales services for the device, a special coupling called FLEXIBLE coupling is used to couple the rotating rods between the engine and the oscillating mechanism. has been That is, the rotating shafts transfer the power to the oscillating sole piece.
• Oscillating mechanism: by using an off-axis roller bearing and a horseshoe-shaped part, it applies a controlled back-and-forth oscillation to the shaft carrying the blade (oscillating cutting mechanism) (this mechanical part converts the rotary movement of the motor into a linear movement does). The amount of this fluctuation is very important. A low oscillation prevents the plaster from splitting and a high oscillation causes injury to the patient’s skin.
• The mechanism for changing and controlling the speed and power: this feature allows the operator to change and increase or decrease the operating speed (oscillation of the blade) according to the needs of the operator and the type of material and thickness of plaster and according to his needs. The speed change in Rayin Sanat plastering saw is done by changing the speed in the main engine. To change the speed of the plastering saw, there is no need to turn off the device, and this change is done using the volume key installed on the converter section (electronic power supply) of the device. It should be noted that using the right speed for cutting can help prevent areas such as temperature increase, excessive wear of blade teeth and power transmission parts and unnecessary pressure.
• The ability to operate with a rechargeable battery built into the power case when the input power is cut off
• Additional parts: Rayin Sanat medical plastering saws have additional parts that give the user more possibilities. These parts include:
  • The special screw (blade lock) for quick blade replacement is a system to facilitate the heat transfer of the engine from the body and the place where the blade sits on the body. It is possible to quickly detach the blade from the body of the saw and install a new blade quickly and easily. It should be noted that the possibility of changing the blade with a new and sharper blade increases the useful life and efficiency of the device.
  • Wrench for changing the blade
• Control system: The plastering saw has a control system that includes an on/off switch and speed control volume. These systems allow the user to control the operation of the device and ensure safety in use. For this purpose, two on/off keys have been installed, one on the device itself and the other on the power supply case. The use of two keys somehow increases the device’s power and adds a step to prevent unwanted movement or possible user error. .
• Ease of use: Rayin Sanat plaster saws are much easier to use due to the use of a DC electrical system. The user only needs to turn on and off the feeding device, which is also designed separately and on the table, and does not need to apply pressure or special mechanical movement. This feature allows the user to be more efficient and control.
• Ability to be lightweight: due to the separation of its supply source from the device and the creation of a desktop case for it, the Rayin Sanat plastering saw has given the user more scope of action and the lightness of the device does not cause fatigue of the user and pain and muscle cramps due to the weight and vibration. reduces This feature allows the user to use it easily and without restrictions in different places.

According to the mentioned cases, Rayin Sanat’s plastering saw with the ability to be used by one hand can allow doctors to work with the other hand and improve performance.

• Safety and protection system: The safety issue of the device can be separated into two areas, electrical and functional. The safety of patients and doctors is very important when using plaster saws. The characteristic of no damage when dealing with the skin and surrounding tissues of the patient’s limb is determined based on the determination of the swing course of the blade. That is, in terms of functionality, the design of the device has been done in such a way that no injury is caused by the contact of the blade with the patient’s skin, while this device immediately creates a cut when it is placed on hard surfaces such as plaster. In the field of electricity, Rayin Sanat’s plastering saws have completely reduced the risk of electrocution due to the use of 24 V electricity as the operating voltage and the resulting risks on the operator and the patient. The cases that have a risk of occurrence are the risk of damage to the connecting wire or the risk of cutting the wire during operation, which are eliminated in Rayin Sanat’s plastering saw due to the use of 24-volt electricity.
• Good stability of the device: due to the use of the power switch converter system, changes and fluctuations in voltage and input current as well as output current to the motor have more control and the device operates in a more stable state.
• Ergonomic design: The design of the plaster saw is based on comfortable and consistent use by doctors. The location of the device provides the user with a high operational capability.

The isolation of the electrical power supply and its connection to the device by a wire rope allows the operator to easily access areas far from the patient and perform better.

• Ability to clean and disinfect: In order to maintain health and prevent infection, the plaster saw can be washed with cleaning and disinfecting materials, just make sure that the washing conditions are based on the IPX2 standard.
• Repairability: The ability to replace parts and easy repair can also be one of the additional advantages of this device. That is, the body of the device is designed in two pieces, which gives the repairman the ability to access the two head mechanisms and the engine output coupling separately.
• Efficiency and speed: The plaster saw has the capability of fast cutting with high efficiency (motor speed more than 16000rpm) and thus the time of cutting plaster or fiber is reduced and allows doctors to use it effectively.
• Vibration reduction: the small size of the body increases the natural frequencies of the resonance factor, and this, along with the use of high-power dc motors and flexible coupling mechanism, has a significant effect on damping the annoying and tiring vibrations of the user.
• Easy portability: Due to its lightness and small volume, the Rayin Sanat plaster saw can be easily transported and can be packed in a bag. This will help doctors and operators in the integration of use and 5S. It also allows the operator to easily move the device and its accessories from one room to another.
