Problems solved by technology

Existing tip designs for osteotomies have serrations at the tip that result in irregular bone cuts
The surgeon's motion to produce the cutting effect requires rotation of the hand piece, which requires the wrist and larger muscle groups to control the bone cut, resulting in imprecise bone cuts with this design
Also, some osteotomy tips have abrasive walls that rely on diamond coating to provide abrasiveness, generating excessive heat

Embodiment Construction

[0017] A surgical system for bone surgery according to the invention is provided with a handpiece comprising a tip capable of operating on bone tissue. For this purpose, various means other than the tip can be mounted on a suitable handpiece according to selected embodiments described below. The handpiece must provide external and / or internal flushing of the tip. Additionally, lighting can be provided for improved visibility.

[0018] The surgical system may also have a controller console with dedicated software to control the electrical sensitivity of the system and the selective application of vibrational energy. Optionally, the console's controller has a touchpad or keypad or foot pedal for operator input and control.

[0019] Control electronics allow the operator to control the application of vibratory energy, including modulation between low frequency pulses and high frequency pulses. In this way, the user controls the vibrational energy that is ultimately delivered t...

Abstract

A series of tips for use with an ultrasonic or piezoelectric dental surgical device dental are used in osteotomy, ostectomy and osteoplasty procedures or any procedure requiring removal or shaping of bone or other hard tissues. In some embodiments, fissures are provided in a cutting end of the tip to facilitate osteotomy. The tips are shaped so that they are comfortable for the surgeon to use in a proper position, so that when a handpiece to which the tips are releasably attached is held in the conventional manner, the geometry of the osteotomy will be precise and desirable. When energized, the tips readily cut through bone or facilitate shaping of skeletal structures at the surgical site. Methods for use of the tips and systems in which the tips provided the cutting function are also described.

Description

technical field [0001] The present invention relates to the field of surgical devices for osteotomy, osteoplasty and osteotomy, and in particular to tips for piezoelectric surgical systems used in oral surgery. technical background [0002] Orthopedic surgery involving cutting for the shaping of bone tissue ((osteotomy), (osteotomy), and (osteoplasty) is notoriously difficult and requires precision and the application of large mechanical forces to alter mineralization. Reshape bone or remove bone tissue. [0003] Traditionally, osteotomy, osteotomy, and osteoplasty have been performed using manual chisels and other hand-held instruments, rotary drills, oscillating saws, and reciprocating saws. Manual instruments have proven to give unsatisfactory results, usually in part because of the bone's tendency to shatter or crack in unpredictable ways. The limited applications of saws are limited to straight cuts. Saws also generate excessive vibration and are difficult to maneuve...
