Description

Technical Field [0001] The present invention relates to a bone processing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bone processing apparatus capable of cutting unnecessary tissue attached to a bone and cutting the bone, and a processing method using the same.

Recently, the importance of biomaterials required for the development of medical technology and the increase of treatment for accidents, disasters and skeletal system related diseases are increasing day by day. Biomaterials are artificial, natural or composite materials other than medicines, and refer to materials used for treating, reinforcing, replacing, or restoring the function of tissues or organs of the human body in the human body for short or long term.

In the case of bone deformation due to the inherent or acquired bone disease of humans and damage due to external stimuli, a bone graft substitute is implanted into the patient in order to repair the bone defect site. In this case, A bone graft from a donor body, a sterilized sterilized whole bone graft material, a heterogeneous bone graft material derived from a pig or a bovine bone, and a synthetic bone graft material made of calcium and apatite.

Allogeneic bone graft materials have excellent bone regeneration ability and are used as filling materials in areas where bone regeneration is slow or impossible in orthopedics and dentistry fields. It is also used for replacing the bone loss site and reinforcing the joint fixation, and is also used for treatment of bone, bone trauma, and fracture.

The allogeneic bone graft material is made of a graft material, and unnecessary tissues (fascia, periosteum, fat, muscle, ligaments, etc.) attached to the bone are removed before the graft material is manufactured into the graft material, A preprocessing process is carried out to cut it to an appropriate size.

Conventionally, the task of removing unnecessary tissue has been manually removed by technicians using a small knife. In such a case, it takes a lot of time to work, resulting in low work efficiency and productivity, and sometimes passive work progresses to increase the fatigue of workers and injure them. In addition, the coated bone has been subjected to a cutting process using a conventional band saw to facilitate grinding. However, the fracture machine occupied a large space due to a large equipment, and it was impossible to disassemble and assemble it, making it difficult to clean equipment and sterilization. In addition, since the two processes are processed by using different equipment, there is a problem that the time and labor are reduced and the productivity and productivity are lowered.

Therefore, there is a need for a bone processing device that is efficient in bone processing and can increase productivity.

For example, a long bone having a diameter of 1 to 5 cm and a length of 15 to 50 cm was processed.

Since the bone thus collected has a considerable amount of unnecessary tissues attached thereto, it is necessary to remove foreign matter, which is an unnecessary tissue of the bone. More specifically, the trimming unit 210 is mounted on the rotating shaft 130 of the bone processing apparatus 10 of the present invention to drive the motor. When the foreign material of the bone is removed, the trimming means 210 attached to the rotary shaft 130 is removed, and the cutting means 220 is mounted and operated to cut the bone to be processed to a predetermined size.

Particularly, in cutting the bone, cutting water can be supplied to the cutting means 220 through the cutting water supply nozzle 310 to prevent damage to the bone by the heat generated in the cutting blade 221 of the cutting means 220 have.

The bone thus processed can be stored with a reagent treatment.
