AI Technical Summary

Benefits of technology

This new type of device helps punch through hard tissue accurately without having safety systems or requiring precise measurements for finer precision than regular tools like common ones.

Problems solved by technology

This technical problem addressed in this patented text relates to both conventional regular bone tools with limited capabilities such as being safe without having an automatic lock mechanism or requiring manual measurement techniques that may lead to unsafe conditions during surgery due to potential hazards associated therewith.

Abstract

The self-locking refined quantitative osteotome includes one osteotome with screw hole, one osteotome sheath with slot to coat three sides of the osteotome, one locking screw, and one regulating screw connected between the stretched arm of the osteotome and the stretched arm of the osteotome sheath. The osteotome has scale in the position to combine with the osteotome sheath. The osteotome is provided in different sizes and its feeding depth may be controlled precisely, so that the present invention can control the bone taking amount and range quantitatively.
