Surgical pin extractor using kinetic force and automatic blocking of the pin on the apparatus

摘要

Device making it possible to pull out surgical pins. The invention allows easy and adapted extraction of surgical pins with different diameters, without bearing on the support into which they are driven. It consists of an outer part (1, 2) sliding on an inner part (3, 4, 6) until it abuts thereon. Throwing the body (1) facilitates extraction of the pin by the kinetic energy released at the moment of this arrival in abutment. Furthermore, the inner part (3, 4, 6) produces automatic blocking of the pin introduced into the apparatus by bracing of a plate (6) which lies in the inner part and which is positioned obliquely with respect to the axis of the pin, either by gravity or by the inertia created at the moment of throwing the body (1). The device according to the invention is particularly intended for extracting surgical pins. IMAGE
