Product details

The Arthroscopy Tapered Shaver Blade offered by Manners Technology is a specialized instrument designed for precise tissue resection in orthopedic surgery. It consists of an outer hollow sheath and an inner rotating cannula, forming a "tube within a tube" mechanism. The window in the inner sheath acts as a dual-edged cylindrical blade that rotates within the outer tube. The shape and geometry of both the inner and outer tube tips determine the blade's cutting aggressiveness, enhancing intraoperative functionality and precision for incising or removing soft tissue, hard tissue, or bone.

Blades are available in standard materials such as 304, 316L, L605 and Ni-Ti, with custom sizes available upon request. For improved performance, our engineers recommend the use of 630 stainless steel (17-4PH) for the blade tips, which are heat treated to achieve a hardness of HRC 52-56. This hardening process ensures high durability and a superior surface finish for the outer tube tip, maintaining a sharp cutting edge.

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 Arthroscopy Tapered Shaver Blade offers a tapered design, providing several advantages. Its tapered tip enables easy access into and around joint spaces, while the oval shape of the outer window limits clogging by restricting tissue size. With dual inner cutting windows, the blade ensures precise cutting edges for clean and aggressive tissue resection, enhancing surgical efficiency and precision.

The manufacturing process begins with heat treatment to harden the blade tip. A Sliding Headstock Lathe (Citizen L12-1M7) is then used to hollow out the tip to ensure smooth inner walls. If toothed edges are required, they are precision ground on a grinder. A Grinding Machine is used to achieve the desired shape, sharpness, cutting depth, number of flutes, tooth profiles and thread angles to meet specific customer requirements.

Due to the different hardness levels of the tip and shaft materials, the two parts are laser welded together after machining. For curved blades, the inner tube is laser cut and the outer tube is bent on a bending machine to join the inner and outer tubes. A 5-axis Laser Cutting Machine ensures high precision, fine slots, better edge quality, and the ability to achieve slot widths between 15μm and 30μm. This results in an extremely flexible inner tube that maintains a consistent rotational speed, minimizing the impact on cutting even in curved designs.

After the machining process, the Arthroscopy Tapered Shaver Blade undergoes electrolytic polishing to enhance its surface finish and remove imperfections. This process helps achieve a smooth and uniform appearance. Following polishing, the blade undergoes ultrasonic cleaning to remove remaining contaminants and debris. This thorough cleaning process ensures the blade is free from any particles that could compromise its performance or pose a risk to patient safety.

Once cleaned, the blade is then subjected to injection molding. Injection molding is a method to obtain molded products by injecting plastic materials molten by heat into a mold, and then cooling and solidifying them. The method is suitable for the mass production of products with complicated shapes, and takes a large part in the area of plastic processing.

Finally, the blade undergoes rigorous quality inspection to ensure it meets the highest standards. Various tests and measurements are conducted to verify its dimensions, surface finish, and overall performance. Any deviations from the specifications are addressed promptly to maintain the quality and reliability of the product.
