Surgical device and method for bone surgery

Abstract

A surgical device ( 1 ) for bone surgery including a body ( 2 ) able to be gripped by the user and a tip ( 3 ) mounted at the head of the body and set in vibration at a modulated ultrasonic frequency to operate on bone tissue, the surgical device ( 1 ) being particularly suitable for oral surgical procedures such as bone sampling, excision of cysts, third molar extraction, preparation of alveolar sites, creation of an opening into the maxillary sinus (Caldwell Luc), elevation of the maxillary sinus by the crestal route and orthopedic and neurosurgical procedures such as osteoplasty, ostectomy and osteotomy.

1 . A surgical method for bone surgery, characterized in that it provides a surgical treatment on bone tissue by means of a tip set in vibration at a frequency in the ultrasound range.  
     
     
         2 . A surgical method according to  claim 1 , characterized in that it is used in orthopedic and neurological surgery.  
     
     
         3 . A surgical method according to  claim 1 , characterized in that it is used in osteotomy treatments.  
     
     
         4 . A surgical method according to  claim 3 , characterized in that said osteotomy treatment provides bone restriction, breaking the continuity of the skeletal segment, by means of a osteotome tip set in vibration at a frequency in the ultrasound range.  
     
     
         5 . A surgical method according to  claim 1 , characterized in that it is used in osteoplasty treatments.  
     
     
         6 . A surgical method according to  claim 1 , characterized in that it is used in ostectomy treatments.  
     
     
         7 . A surgical method according to  claim 1 , characterized in that it is used in oral, maxillo-facial and otorhino-laryngol surgical procedures.  
     
     
         8 . A surgical method according to  claim 7 , characterized in that it is used in surgical procedures for implantation on an edentulous ridge.  
     
     
         9 . A surgical method according to  claim 8 , characterized in that it comprises the following steps: 
 horizontal crestal incision on edentulous ridge, by a chisel tip operated by ultrasound, so that it performs an extremely precise and fine incision,    widening of said incision, by means of a chisel tip, with widened point, operated by ultrasound, to separate the vestibular cortical bone wall from the palatal one,    creation of at last one implant site on the bottom of the widened horizontal crestal incision, by means of an osteotome tip operated by ultrasound,    positioning of implants in the implant sites respectively.    
     
     
         10 . A surgical method according to  claim 7 , characterized in that it is used for bone tissue incisions for bone sampling in hardly accessible anatomical areas.  
     
     
         11 . A surgical method according to  claim 7 , characterized in that it is used for excision of at least one of cysts, inflammatory tissue or phlogistic tissue.  
     
     
         12 . A surgical method according to  claim 7 , characterized in that it is used for extraction of impacted third molars in the vicinity of the dental alveolus.  
     
     
         13 . A surgical method according to  claim 7 , characterized in that it is used for creation of a bone opening into the maxillary sinus (Caldwell-Luc) without damaging the sinusal membrane, and elevation thereof.  
     
     
         14 . A surgical method according to  claim 7 , characterized in that it is used for elevation of the maxillary sinus by the ethmoidal crest route.  
     
     
         15 . A surgical method according to  claim 1 , characterized in that it is used for vertebral laminectomy treatments.  
     
     
         16 . A surgical method according to  claim 7 , characterized in that it is used for hand and foot bone surgery.
