Abstract

A bone piece collector wherein a blade (4) coming into tight contact with the surface of a filter (2) under an appropriate pressure is provided in order to prevent lowering in the efficiency of suction work due to sampled bone chips adhering to the surface of the filter (2) in the bone piece collector provided in a suction line in order to sample a bone, i.e. a transplantation material in autologous bone transplantation, the blade (4) is rotated while being pressed against the surface of the filter (2) with a finger pressure or a motor drive force, and the sampled bone chips are moved in a certain direction so that clogging of the filter (2) is eliminated and the suction efficiency can be recovered at any time.

Claims

1. An autogenous bone collection device used along a suction path to suction objects such as cooling liquid, speckles of bone, saliva and blood, wherein after the speckles of bone are suctioned, the speckles of bone are separated from the other objects by a filter, comprising:

a blade rotatably contacting an inner wall of the filter, and the blade rotated to move obstructions stacked on a surface of the filter in an arbitrary direction to remove the obstructions of the filter, whereby suction efficiency is held constant; and

a suction nozzle side rotatably connected to the filter.

2. The autogenous bone collection device as claimed in claim 1, wherein the blade is fixed to a main body and rotated by a motor to move obstructions stacked on a surface of the filter in an arbitrary direction, to remove the obstructions of the filter, whereby suction efficiency is held constant.

3. The autogenous bone collection device as claimed in claim 1, wherein the speckles of bone collected in the filter are collected in an arbitrary position of the filter by rotating the blade, which contacts the inner wall of the filter.

4. The autogenous bone collection device as claimed in claim 1, wherein the autogenous bone collection device comprises a main body partially or entirely covered by a shrink film to prevent junction air leakage, the main body having an integrally formed air leak hole covered by the shrink film, and the shrink film not obstructing the rotation of the blade.

5. An autogenous bone collection device comprising:

a filter having an inner wall;

a blade, rotatably connected to the filter, contacting the inner wall of the filter, wherein the blade is rotated to remove obstructions on the filter; and

a suction nozzle side rotatably connected to the filter.

6. The autogenous bone collection device as claimed in claim 5, further comprising:

a motor, driving the blade, connected to the suction nozzle side.

7. The autogenous bone collection device as claimed in claim 6, further comprising:

a base, wherein the filter is connected between the suction nozzle side and the base; and

a shrink film covering the base.

8. The autogenous bone collection device as claimed in claim 5, wherein the filter has a net, and the blade has a contacting portion pressing against the net while rotating.

9. An autogenous bone collection device, comprising:

a suction nozzle side;

a base, configured to connect to a vacuum source and defining a suction path from the suction nozzle side to the base;

a filter, connected between the suction nozzle and the base, wherein the suction nozzle side is rotatable relative to the filter; and

a blade rotatably disposed in the filter, arranged such that during rotation thereof the blade contacts an inner wall of the filter so as to remove obstructions collected on the inner wall of the filter.
