MECHANICAL REMOVAL OF PERIODONTAL GRANULATION TISSUE

这一拟议努力的目标是发展 该机械外科装置将能够有效地 有效地去除牙周中遇到的肉芽组织， 手术 目前用于肉芽切除手术的方法 组织是非常耗时和费力的。 此外，增加 对再生手术的强调已经使目前的 可有效去除肉芽组织。 次级 目的是减少或消除与空气污染相关的气溶胶污染， 用目前使用的去除肉芽组织的方法。 申报的手术器械将包括一个改良的钻头， 吸引管 该管插入手术遇到的缺陷 在那里抽吸将肉芽组织拉入管中， 钻头会“抓住”并切割它。吸力也会消除水分 目前，与超声波相关喷雾和微粒污染 用于组织切除。 第一阶段计划集中在制造和体外 测试机械肉芽组织去除器的能力， 有效地去除组织。 第二阶段计划将 旨在评估该手术器械在人体中的作用 临床情况。

The objective of this proposed effort is directed towards the development of a mechanical surgical device which will be capable of efficiently and effectively removing the granulation tissue encountered in periodontal surgery. Methods currently utilized in the surgical removal of granulation tissue are extremely time consuming and laborious. Further, the increased emphasis on regenerative surgery has strained the ability of the currently available armetarium to effectively remove granulation tissue. A secondary objective is to reduce or eliminate the aerosol contamination associated with currently used methods of granulation tissue removal. The proposed surgical device will consist of a modified bur running in a suction tube. The tube is inserted into surgically encountered defects where the suction will pull the granulation tissue into the tube and the bur will "grab" and cut it. The suction will also eliminate the water spray and particulate contamination associated with ultrasonics currently used for tissue removal. The Phase I program is concentrated towards the fabrication and in vitro testing of the mechanical granulation tissue remover for its ability to remove tissue effectively and efficiently. The Phase II program will be oriented toward the evaluation of this surgical instrument in human clinical situations.
