Description

Bone collector {Bone collector}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bone collecting device, and more particularly, to a bone collecting device that collects bone tissue of a patient, which is inhaled while blood is in operation, and can be utilized as a food material.

Bone materials are needed to fill the spaces between the bones or between the bones and the implants in the operations that require cutting or perforation of the bones, or in surgeries that replace bone defects with implants. In this case, the bone of another person, the patient's own bone, or an artificial bone molding material is used as a bone food material.

Although the bone of the autologous tissue is most preferable due to the rejection reaction and the like, in order to obtain the bone of the autologous tissue for surgery, a separate operation must be performed, and the amount of bone obtained therefrom is also limited.

Therefore, there is a need for a technique capable of recovering the bone of the autologous tissue, which is leaked at the time of surgery, without loss, for fusion.

US Pat. Nos. US8845605 and US8920393 disclose a bone collection device that alternately couples a first cover and a second cover. The above two patents have disadvantages in that it is difficult to replace the two covers and to discharge the collected bone (hereinafter referred to as a " cake ") after the bone collection is completed.

U.S. Patent No. 8845605 discloses a technique in which a bone is collected in a retainer having an elastic concave groove and is placed in a container and filled with liquid and then pressed by a press to push the bone tissue, Is removed. However, there is a problem in that a separate collecting device is required since the bone must be collected prior to the retainer.

Korean Patent KR1608240B is an improved version of U.S. Patent No. 8845605, in which a shaft of a press is formed into a tubular body to connect a suction device for providing a negative pressure therethrough, and a blood product containing bone material flowing through a suction port is pressed by a press, . However, when pressed by a press, the blood product can flow freely through the shaft tube body, and a complete cake can not be produced.
