Product Specification

The blade consists of an outer hollow sheath and an inner hollow rotating cannula, forming a "tube within a tube" mechanism. The inner sheath's window acts as a dual-edged cylindrical blade rotating within the outer tube. The shape and geometry of the inner and outer tube tips determine the blade's aggressiveness. Both work together can help to improve intraoperative functionality and precision when incising or removing soft tissue, hard tissue, or bone.

They are available in standard and long lengths, curved and straight styles, and shaft diameters ranging from 1.9 to 5.5 mm, depending on the joint involved and the procedure to be performed. Smaller blades allow access to smaller or more constrained joints. Manners Technology offers a wide array of blades and burs capable of supporting even the most challenging surgical procedures.

The tapered design of the Arthroscopy Tapered Shaver Blade offers numerous benefits. Its tapered tip facilitates easy access into and around joint spaces, while the oval shape of the outer window reduces clogging by limiting tissue size. Equipped with dual inner cutting windows, the blade provides precision cutting edges for clean and aggressive tissue resection. Additionally, its design allows for easy access to tight spaces, difficult-to-reach anatomy, and sensitive areas, making it a versatile tool that enhances surgical efficiency and precision.

Standard blades are stocked in 304, 316 L, L 605, Ni-Ti, and other exotic alloys in Manners Technology. Custom sizes can be quoted to request. In the workshop, our engineers suggest that the tip of the blade material should be 630 or 17-4 for hardening treatment, with a hardness of HRC 52-56, and this is commonly done to ensure high hardness and better surface finish of the inner tube tip head. Manners is always committed to offering maximum performance and durability.

After being heat-treated for hardening, the blade's tip is hollowed out using a five-axis CNC machine to ensure smooth inner walls. If designed with toothed edges, these are then precision-ground using a grinding machine. Utilizing a five-axis CNC grinding center, the blade can be precision-ground into any desired shape, meeting customers’ requirements for sharpness, cutting-edge depth, number of flutes, tooth profiles, and thread angles. 

Due to the different hardness of the materials used for the tip and shaft, after the tip is machined, the two parts are welded together using laser welding technology.

However, if it is a curved-style shaver blade, the inner tube needs to be laser cut, and the outer tube needs to be bent using a bending machine to assemble the inner and outer tubes. Manners uses a 5-axis laser cutting machine to cut the inner tube, resulting in higher precision, finer slits, better edge quality, and the ability to meet different slit widths between 15um and 30um. This produces an inner tube that is extremely flexible, ensuring that even in curved designs, the rotation speed of the inner tube remains unchanged, thereby minimizing the impact on cutting.
