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.

这项拟议工作的目标是针对发展 一种机械外科设备，它将能够有效地和 有效去除牙周组织中的肉芽组织 做手术。目前外科手术中去除肉芽组织的方法 组织是非常耗时和费力的。此外，增加的 对再生手术的重视已经使目前的 可有效去除肉芽组织。次要的 目标是减少或消除相关的气溶胶污染 用目前使用的方法去除肉芽组织。 拟议的手术装置将包括一个改装的磨刀，在一个 抽吸管。将管子插入到手术中遇到的缺陷中 在那里吸力会把肉芽组织拉进管子里 Bur会“抓住”它，然后把它切开。吸力也会把水吸走。 目前与超声波有关的喷雾和颗粒污染 用于去除组织。 第一阶段的计划是集中在制造和体外 对机械肉芽组织清除器的性能进行了测试 有效、高效地去除组织。第二阶段计划将是 面向人体对该手术器械的评价 临床情况。
