In one embodiment, a tissue planing assembly includes a base frame, a plurality of disassemblable components assembled to the base frame and having a ready configuration, a sample conveyor, a blade assembly configured to be coupled to the base frame, a control unit communicatively coupled to the sample conveyor, and one or more component sensors communicatively coupled to the control unit. The plurality of disassemblable components is configured to support a tissue sample. The sample conveyor is configured to convey the tissue sample through the blade assembly. The one or more components sensors are configured to output a signal indicative of at least one of the plurality of disassemblable components missing from the ready configuration, wherein the control unit prohibits operation of the sample conveyor when at least one of the plurality of disassemblable components is missing from the ready configuration.

Tissue planing assemblies and methods

A method of preparing a reconstitutable implantable bone putty includes combining a bone matrix derived from human bone and gelatin particulates derived from human tissue at a concentration of the bone matrix by dry weight of 20 to 60 percent to form the reconstitutable implantable bone putty. Preparing the gelatin particulates includes supplying a gelatin precursor of bone or soft tissue from a human, treating the gelatin precursor with phosphoric acid to generate a gelatin-acid mixture, neutralizing the gelatin-acid mixture with an alkali to a pH between 6 and 8 to allow a gelatin-rich solution and a waste solution to separate, removing residual salts from the gelatin-rich solution to obtain purified gelatin, drying the purified gelatin, and reducing the purified gelatin to particulates having a largest dimension less than 300 &#x3bc;m. A method of preparing an implantable bone putty includes adding a reconstitution media to the reconstitutable implantable bone putty.
