We sold medical electric saw saw a lot of customers have different speed sawing saw do not understand, the same are electric drill, why have different speed requirements?
As the classification of orthopedic drill is divided according to different surgical sites and different operations (such as craniotomy and skull milling is mainly used for brain surgery), then the different medical electric saws on the natural speed of the different requirements. Take the acetabular grinding drill, for example, in the joint replacement surgery we need to remove the broken joint at the same time need to use the acetabular grinding drill on the cutting surface for grinding and correction, this time we require the acetabular grinding drill speed can not be too fast, In the 0-400 r / min or so. If the speed is too fast easily lead to bone burns and necrosis, and we know that a reason - the rated power of the speed and torque inversely proportional to, if the speed is too fast then the cross-section of the power will be very small, so medical saw can only finish deep Drill can not be finished grinding, so acetabular grinding drill is also known as "slow drilling". On the contrary, bone drilling is mainly used for trauma surgery to play steel plate screws and orthopedic drilling, in the actual operation does not require excessive torque and the need for faster speed, so the speed is generally required in 0-1100 r / min or so.
The above is just a list of two examples to illustrate the reasons for the different speed of orthopedic electric sawing, Shanghai Bo Jin medical equipment company in the production and development of medical electric saws will be the speed of the study, according to the actual operation of the surgery and the results of the experiment , According to the use of medical electric saws to develop different speed, to ensure that doctors in the fast completion of the operation at the same time will not affect the bones, so I also hope that customers in the purchase of medical electric saws when the product also has a certain understanding.
