Design and Manufacture of a Smart Orthopedic Pin Cutter for Use in the Operating Room and Patients Undergoing Orthopedic Surgery

Background and Aim: Since pin cutter is used in surgical operations involving screw and orthopedic plating and this is one of the most sensitive surgeries, saving time is very important along with reducing infection rate. The purpose of design the Mini-Pin Cutter is to replace a smaller, lighter, more efficient device than conventional and traditional cutters, which ultimately results in a comfortable, clean, and faster shear, resulting in shorter operating time. Methods: This is a descriptive study with design and manufacturing approach. This means that before preparing and assembling the components of the system, first, using force engineering software (ABAQUS and CATIA), the force analysis was done (design approach). Then, after modeling the mechanical parts, the desired parts were prepared for manufacturing and assembly (manufacturing approach). To collect the required data, the subject literature has been used in conjunction with the design team's experiences. Results: The device was designed and built based on the results of orthopedic specialists. It includes an electronic circuit and orthopedic pin cutting blades with high reaction capability in critical situations, which is very useful for speeding up surgery and preventing infection in operating room environments. The designed device is portable with a weight of 1600 grams. Conclusions: The device introduced in this study is a mechanical and automatic system in which tried to eliminate the shortcomings of current and conventional tools. The device is smaller, lighter and safer than existing tools. On the other hand, its’ packing and disinfecting is very easy. The most important advantage of this device compared to old ones is the increasing the cutting speed of orthopedic pins, which reduce surgery time, which is very important in times of crisis and the military.
