AI Technical Summary
The saw teeth of existing medical device saw blades are of a one-piece structure, which requires replacement of the whole piece after wear, increasing the cost of use and making it impossible to maintain them individually.
The design allows for quick tooth replacement of medical instrument saw blades. The saw base is accurately positioned and fixed by the cooperation of the limiting groove and the limiting block, combined with the threaded connection, simplifying the saw tooth replacement process.
It enables rapid replacement of saw teeth, ensuring that the equipment returns to normal working performance after replacement, reducing maintenance costs and improving the operational stability of the equipment.
