Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional medical pendulum saw. Background technique [0002] In orthopedic surgery, it is often necessary to use a saw blade to remove the damaged bone tissue of the patient. During the cutting process, in order to avoid excessive bleeding of the patient, the smaller the wound, the better. High-speed oscillating cutting within the stroke, due to the small swing and high swing frequency, the oscillating saw can only remove bone tissue without hurting muscles, soft tissues and nerve tissues. However, the medical oscillating saw in the prior art, The motor is placed horizontally, parallel to the swing shaft and the split fork, and the output torque of the swing saw is related to the size of the motor. This results in a large output torque, which requires a large diameter motor, but the operator needs to be miniaturized, which creates a contradiction , In addi...

[0002] In orthopedic surgery, it is often necessary to use a saw blade to remove the damaged bone tissue of the patient. During the cutting process, in order to avoid excessive bleeding of the patient, the smaller the wound, the better. High-speed oscillating cutting within the stroke, due to the small swing and high swing frequency, the oscillating saw can only remove bone tissue without hurting muscles, soft tissues and nerve tissues. However, the medical oscillating saw in the prior art, The motor is placed horizontally, parallel to the swing shaft and the split fork, and the output torque of the swing saw is related to the size of the motor. This results in a large output torque, which requires a large diameter motor, but the operator needs to be miniaturized, which creates a contradiction , In addition, because the pendulum saws currently on the market do not have an effective sealing structure, the blood during use will enter the inside of the tool, causing corrosion of internal parts, which is also not conducive to secondary disinfection treatment
