SURGICAL FORCEPS FOR LATERAL OSTEOTOMY OF NASAL BONE

摘要

This invention relates generally to surgical tools and more particularly to such tools and methods used in lateral Osteotomy of the nasal bone. The designing process was initiated by studding the basic anatomy of the nose. Lever 1 mechanism was studied to design the forceps. It is experimentally calculated that gripping force is 250N-450N. The length of forceps was designed such as to transfer sufficient force to break the bone. Considering the above dimension and tolerance space available inside the nose the designing was completed. A Rapid Prototype model of the designed model was generated so that the surgeon could examine the forceps closely and suggest for modification. The fabrication process was initiated after this. The fabricated forceps was given to the surgeon for inspection. After getting confirmation from the surgeon, cadaveric study was conducted. The cadaveric study and its observations are discussed in detail. Following invention is described in detail with the help of Figure 1 of sheet 1 showing the assembled view of nasal bone cutting forceps.
