At this time, the filled-out artificial bone or synthetic bone cause biological troubles with alveolar bones or adverse effects may be occasionally produced with poor grafting due to different tissues from the alveolar bones. By considering the problems, a method is employed that transplants patients' bones, namely, autologous bones, minimizing adverse effects in terms of tissue for the filling-out treatment, but it is not easy to harvest autologous bones and the expense for that is high so that the artificial bones or synthetic bones causing adverse effects as above are used in most occasions.
DISCLOSURE OF INVENTION

It is another object of the present invention to provide a surgical bone- collecting instrument which is easily manufactured by insert injection molding to greatly reduce the manufacturing cost. In order to achieve the above objects, a surgical bone-collecting instrument according to the present invention comprises a grip part formed in an insert injection molding in order for a blade to be placed at the front end thereof; a semicircular protrusion formed on the grip part, opposite to the blade, and forming a bone-passing opening together with the blade; cross walls formed opposite in left and right sides between the blade and the grip part and forming a storage space for collecting the harvested bones by the blade; locking protrusions formed on the upper parts of the left and right cross walls and forming guide grooves in the upper surfaces of the cross walls; and a cover having guide protrusions sliding along the guide grooves, and detachably coupled to the grip part by locking grooves formed to correspond to the locking protrusions.
At this time, in the preferred embodiment, the blade is formed of a stainless steel material, and the blade is formed slanted 70 ~90° toward the grip part.
Further, a slated surface is formed on the upper part of the semicircular protrusion in order for the harvested bones by the blade to easily move into the storage space.
Further, the cover has a storage space narrowed at front in order to be used as a surgical container for storing bones harvested by the blade.
BRIEF DESCRIPTION OF THE DRAWINGS The above objects and other features of the present invention will become more apparent by describing in detail a preferred embodiment thereof with reference to the attached drawings, in which:

BFST MODE FOR CARRYING OUT THE INVENTION Fig. 1 is an exploded perspective view for showing a surgical bone- collecting instrument according to an embodiment of the present invention, and Fig. 2 is a partially cross-sectioned view for showing a surgical bone-collecting instrument according to an embodiment of the present invention.
As shown in Fig. 1 and Fig. 2, a surgical bone-collecting instrument has a grip part 2 formed in an insert injection molding in order for a blade 1 to be placed at the front end thereof; the blade 1 being formed of a stainless steel material to have a certain strength and an anticorrosive property, a semicircular protrusion 3 formed on the grip part 2 and opposite to the blade 1 and forming a bone-passing opening 4 together with the blade 1 to pass harvested bones, cross walls 6 formed opposite in the left and right sides between the blade 1 and the grip part 2 and forming a storage space 7 for collecting the harvested bones by the blade 1 , a slated surface 13 formed on the semicircular protrusion 3 in order for the harvested bones by the blade 1 to easily move into the storage space 7, locking protrusions 8 formed on the upper parts of the left and right cross walls 6 and forming guide grooves 9 in the upper surfaces of the cross walls 6, and a cover having guide protrusions 10 sliding along the guide grooves 9, and detachably coupled to the grip part 2 by locking grooves 11 formed to correspond to the locking protrusions 8.
At this time, the cover 12 has a storage space narrowed at front in order to be used as a surgical container for storing bones harvested by the blade 1, the blade 1 is formed slanted 70 ~ 90° toward the grip part 2 to facilitate harvesting bones when the grip part 2 is held, a cross-sectioned shape of the grip part 2 is formed in a circle, a triangle, an ellipse, a polygon, or the like, and plural protrusions can be formed on the outer circumferential surface of the grip part 2 to prevent the instrument from slipping out when a surgeon holds the grip part 2. Of the drawings, a reference number 15, not described, denotes a reinforcing rib for building up strength around the cross walls 6 extendedly formed with respect to the grip part 2. Hereinafter, operations of the surgical bone-collecting instrument according to the present invention will be described in detail as below with reference to the accompanying drawings.
Fig. 3 is a view for showing a surgical bone-collecting instrument in use according to an embodiment of the present invention.
As shown in Fig. 3, an operator holds the grip part 2, closely touch a patient's bone with the blade 1 , and slowly scratch it with pressure to harvest a predetermined amount of bone. The harvested bone by the blade 1 passes through the bone-passing opening 4 formed between the blade 1 and the semicircular protrusion 3, moves to and is gathered in the storage space 7 formed by the cross walls 6 along the slanted surface 13 formed on the upper part of the semicircular protrusion 3.
At this time, the bone collected in the storage space 7 is prevented from loss by the cross walls 6 and the cover 12 so that all the collected bone can be used for transplanting, and it is not required to collect lots of bone from patient's bone since it is enough with an amount of bone necessary for transplanting.
In the meantime, if the bone-collecting job is completed as above, the grip part 2 is turned 180° for the bone stored in the storage space 7 to move into a storage space of the cover 12. Accordingly, the operator takes out the cover 12 from the grip part 2 in order for the bone stored in the cover 12 to be used for transplanting.
At this time, the cover 12 slides to be separated from the grip part 2 by the guide protrusions 10 of the cover 12 which are coupled to the guide grooves 9 formed on the upper parts of the cross walls 6, and the bone can be easily taken out of the cover 12 through the narrow portion formed on one side of the storage space of the cover 12.
In the meantime, some gums of the patient are cut open in case of transplanting the patient's bone, so it can be easily carried out to collect bone since portions for bone collection exist near the portion to be surgically treated.
INDUSTRIAL APPLICABILITY As stated above, the present invention has an advantage in that an operator can easily harvest a small amount of bone in state that he holds the grip part and closely touches patient' bone with the blade, the loss of bone can be prevented during collecting bone, and the bone-collecting instrument can be simply manufactured.
