Patent ID: 8920171

Claim:
A modular apparatus comprising: a modular component having an implant of a metal pin form, said implant having a blind cylindrical hole; a stump having a tubular cylindrical stem with an enlarged head defining a shoulder, said stump having a cylindrical hole joined with a seat by a collar, said collar having a circular hole, said seat adapted to be coupled with said implant; a tubular cylindrical bar having a first free end and a second end; a first clip comprising: a plate; a cylindrical stem protruding from said plate and adapted to be firmly inserted into said first free end of said tubular cylindrical bar; and a ring disposed on a back of said plate and having a substantially arched external profile defining a circular hole having a cross-section substantially corresponding to a cross-section of said stump, said ring disposed with an axis perpendicular to an axis of said cylindrical stem, said stump having a tapered point having an external diameter decreasing toward said first free end of said stump, said implant being pointed and having an external thread, said tubular cylindrical bar comprising: a plate; and a ring at said second end of said tubular cylindrical bar, said ring of said tubular cylindrical bar having a substantially arched external profile defining a circular hole having a cross-section substantially identical to the cross-section of said stump, said ring of said tubular cylindrical bar having an axis perpendicular to an axis of said tubular bar; and a second clip comprising: a plate; a cylindrical stem protruding from said plate and adapted to be firmly inserted into said first free end of said tubular cylindrical bar; and two identical rings disposed on a back of said plate of said second clip, said two identical rings being in perfect specular position and separated by a space, each ring of said second clip having a substantially arched external profile and defining a circular hole having a cross-section substantially identical to a corresponding cross-section of said stump and disposed with an axis substantially perpendicular to an axis of said cylindrical stem of said second clip, the space between said two identical rings of said second clip suitable for receiving said ring of said tubular cylindrical bar or said first clip such that said stump can be received into the holes of the ring of said second clip and into the hole of said ring of said tubular cylindrical bar or said first clip.
