Power driven bone crusher and method for bone crushing

Abstract

An apparatus for bone milling includes a housing defining a first opening, a second opening opposite the first opening, and a linear passage from the first opening to the second opening. The linear passage has a first surface with third opening there through and a second surface transverse to the first surface. A rotatable cutting member is insertable through the third opening to partially block the linear passage. The rotatable cutting member is positioned at a distance from the second surface of the linear passage corresponding to a predetermined bone chip size.

AI Technical Summary

Benefits of technology

Reduces the cost and time required for orthopedic procedures, increases surgical efficiency, and ensures uniform bone particle sizes, minimizing contamination risks.

Problems solved by technology

Existing bone mills are large, expensive devices which are cumbersome to use and clean and further require re-sterilization at the end of each procedure.

Such re-sterilization takes the form of expensive and time consuming gas sterilization or autoclave sterilization.

When using an autoclave sterilization process, the bone mills can be sterilized and available for reuse in less than a 24-hour period, however, the bone mills are not immediately available.

The resulting period required to re-sterilize the bone mills nevertheless increases the time which necessarily passes between procedures, thereby decreasing operating room and surgical efficiency.

The blade porosity hampers the effectiveness of the cleaning process, which furthers the possibility of contamination during subsequent use of the bone mill.

Additionally, existing mills may only have the capability to produce a single size of crushed bone particles.

As such, a surgical suite needs to have multiple devices to provide crushed bone at different sizes, which greatly increases the cost of having bone-milling capabilities.

Otherwise, a surgeon is disadvantageously forced to use crushed bone having a size either too large or too small for a particular surgical procedure, resulting in potential difficulties during an orthopedic procedure.
