Abstract: Objective In order to overcome the problems that bone rongeur and Kirschner forcep's less function and easy damage, trivial and inefficient, bulky volume, bone and needle broken edge is not neat, needle tail easy spatter wounding and other defects, integrated "U" shaped cutting edge rongeurs of pruning finger-toe and bending-truncating pin is desigened.Methods Pruning-truncating rongeurs set the trimming, bending and shearing, straight and twisting, loading and unloading, filing and stripping, string devices, aintenance functions and other functions in one, compare with bone rongeurs in clinical application.Results Pruning-truncating rongeurs are molding once, manipulation convenient, light and safe, anti damage and maintenance free, cost-effective.Conclusion Pruning-truncating rongeurs are highly integrated and portable anti-lost, preparation instrument swift, man-machine coordination, sharp instrument injury prevention, to improve the operation efficiency.
