Description

Technical Field

[0001] The invention relates to the technical field of pediatric orthopedic saws, in particular to a multifunctional orthopedic saw. Background Art

[0002] Orthopedic oscillating saws are surgical tools commonly used in orthopedic surgery. When in use, the oscillating saw is driven by a motor to drive the saw blade to swing back and forth at high frequency to cut bones, thereby achieving accurate cutting of bones. However, the existing orthopedic oscillating saws do not have the function of position limitation when in use, so that when the oscillating saw is driven by the motor to drive the saw blade to produce high-frequency vibration, it will bring hidden dangers of hand-transmitted vibration disease to doctors who hold the oscillating saw for a long time, and then affect future surgeries and life. Not only that, the existing oscillating saws are also relatively simple in functionality when in use. When in use, they only rely on the doctor to hold them fixedly and then perform surgery, and do not have the corresponding position fixing function. This operation will seriously increase the fatigue of the doctor's arm, causing soreness in the doctor's arm and affecting the smooth progress of the operation. When using the oscillating saw for linear cutting, the cutting position may be offset, causing major medical accidents. For this reason, we propose a multifunctional orthopedic saw.
