The principle of use of electric plaster saw

For ordinary people, the biggest impression of orthopedics is the white plaster cast on the chest of patients, as well as the old crutches, which are the standard equipment of orthopedics. But as long as there is a cast, there is a cast removal, and when the cast is removed, the patient will see the intimidating and liberating electric cast saw. With the rotation of the chainsaw, the patient's plaster shackles will be broken, but once the chainsaw is turned, many patients will have a question full of fear: "Will the cutting chance saw my hand?" In response to this question, Let's start with "gypsum" itself.

The fine powder of anhydrous calcium carbonate is scattered on a special fine-pored gauze bandage, and after soaking in water for a short time, the final shape will be completed, and the final finalized model is what people often call "gypsum". Moreover, a new type of polymer gypsum has also appeared at present, which is made of polymer glass fibers or polymer polyester fibers. Compared with traditional gypsum, this new type of gypsum has the advantages of high strength, low weight, thin layers, breathability and waterproof. However, regardless of the form of plaster, its essence is still a stone-like body similar to cement, which makes the removal method of both the same, that is, cutting with a plaster saw.

The electric plaster saw uses a low-voltage DC motor to drive the gear at the end, and there are countless blades distributed on the gear. The rotation of these blades makes the object to be cut withstand countless times of blade chopping at the same time, that is, "reciprocating cutting". With the continuous slashing of these blades, the cutting action was finally completed. To put it simply, the teeth of the medical cutting machine will not rotate a full circle, it will only vibrate in a high-frequency, small-amplitude mode. This cutting method, when it touches the human body, is like a massage machine, except for high-frequency vibrations, there is no more impact.
