Embodiment Construction

[0025] refer to figure 1 and 2 , shows a method 100 and system 200 that may be used to process material for medical use. The methods and systems are discussed below with respect to autografts from patients, but are also applicable to materials such as allografts, synthetic materials, including one or more of autografts, allografts, and synthetic materials. combination within. Other materials may include bone morphogenetic protein (BMP), demineralized bone matrix, hydroxyapatite (HA), coral, and the like. In method 100 and system 200, a tissue sample 202 is obtained from a patient using known surgical bone harvesting techniques (step 102). Tissues harvested include bone and non-bone tissues such as muscle, periosteum, and connective tissue. The harvested tissue sample 202 is then placed into a bone stripper 204 (also referred to as a bone stripper) that removes tissue from the bone (step 104).

[0026] Stripping, as used herein, refers to the removal of non-osseous tissue...

Abstract

A system and method for treating bone is disclosed. A tissue separator is utilized to separate tissue, including at least one of muscle, periosteum, and connective tissue, from bone in a safe, sterile, and efficient manner. In one aspect, the particle reducer can include an impeller (206) positioned relative to a cutting surface on the drum (204). At least one of the impeller and the drum is rotated by the power source such that harvested tissue is in friction fit with the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.

Description

[0001] The patent application of this invention is an invention patent with the international application number PCT / US2010 / 061988, the international application date is December 23, 2010, and the application number entering the Chinese national phase is 201080065177.X, and the name is "Bone Treatment System and Method" Divisional application of the application. Background technique [0002] Granulated bone particles are used in a variety of medical and surgical procedures. For example, finely granulated bone particles can be used in spinal fusion to repair defects due to injury, graft surgery, or tissue reconstruction. In order to process bone for use in medical and surgical procedures, several bone processing steps are taken. In an example procedure, a tissue sample, including bone, is surgically removed (ie, harvested) from a patient. After the bone is removed from the patient, non-bone tissue (eg, muscle, periosteum, connective tissue) is removed from the bone to prepare...
