The materials of surgical scrub brushes are diverse, mainly including the following categories:

Materials of the Brush Head

  • Natural Bristles: Made from natural hairs such as pig bristles, they are soft and have good elasticity. They can effectively remove dirt and impurities without damaging the skin or the surface of surgical instruments. Natural bristles also have good water absorption, which can better cooperate with cleaning agents to play a cleaning role. They are suitable for preoperative skin cleaning with high requirements for skin irritation, as well as the cleaning of some smooth and delicate surgical instruments.
  • Synthetic Fibers
    • Nylon: The brush head made of nylon has high strength, good wear resistance, and excellent elasticity and flexibility. It can maintain its shape and performance after repeated use and cleaning. It also has good chemical stability and is not easy to react with disinfectants and other chemical substances. It can be used for the cleaning of various surgical instruments and is also suitable for some skin preparation work that requires strong cleaning power.
    • Polyester: The polyester fiber brush head has excellent corrosion resistance and antibacterial properties, which can effectively prevent the growth of bacteria and reduce the risk of cross-infection. Its surface is smooth, and it is not easy to retain dirt, making it easy to clean. It is commonly used in the cleaning of surgical instruments and wound debridement.
    • Polypropylene: The brush head made of polypropylene has good water resistance and chemical stability, and its texture is relatively hard. It is suitable for cleaning stubborn stains and dried substances attached to the surface of instruments. However, when used for skin cleaning, attention should be paid to the force to avoid damaging the skin.
  • Sponge: The sponge brush head is soft in texture and has strong water absorption. It can evenly apply cleaning agents and is suitable for the cleaning of sensitive skin areas, such as the skin preparation before surgeries around the face and eyes. At the same time, it can be made into different shapes and densities according to needs to meet different cleaning requirements.

Materials of the Brush Handle

  • Plastic
    • Polypropylene (PP): The PP material brush handle is lightweight and low in cost. It has good corrosion resistance and insulation properties and is easy to be processed and molded. It can be made into various shapes and colors, which is convenient for medical staff to distinguish and select according to different usage scenarios and needs.
    • Polycarbonate (PC): The PC material brush handle has high strength and transparency, with a beautiful appearance and good impact resistance. It can withstand a certain degree of external force extrusion and collision and is suitable for surgical scrub brushes with high requirements for the quality and durability of the brush handle.
  • Metal
    • Stainless Steel: The stainless steel brush handle has excellent corrosion resistance, strength, and rigidity. It can maintain stable performance in high-temperature and high-pressure disinfection environments and is not easy to deform or damage. It is often used for cleaning brushes of surgical instruments that require frequent disinfection and have extremely high hygiene requirements, as well as some scrub brushes that need to withstand greater force.
    • Aluminum Alloy: The aluminum alloy brush handle is lightweight, has relatively high strength, and has good thermal conductivity and corrosion resistance. Its surface can be processed by oxidation treatment and other processes to increase its aesthetics and wear resistance. It is suitable for some surgical scrub brushes with requirements for weight and a certain degree of strength.
  • Composite Materials: Different materials such as plastic and metal are combined. For example, the grip part of the brush handle uses plastic material to provide a good hand feel and anti-slip performance, while the part connected to the brush head uses metal material to enhance the firmness and stability of the connection. It combines the advantages of different materials and improves the overall performance and user experience of the scrub brush.
