PROBLEM TO BE SOLVED: To provide a filling jig for artificial bone material capable of performing filling work with controlled amount of filling for a target site even to a deep part of a surgical field of the body without scattering or falling of material to the area around when filling a bone defective part with a powdery or granular artificial bone material.SOLUTION: The device according to the present invention is a filling jig for filling powdery or granular artificial bone material into a gap part of a bone and is composed of a funnel section and a throat section. The internal walls of the throat section is formed with ridges and grooves in a parallel direction with the central axis when viewed in a cross section, and the cross section of the throat section can be easily deformed by pressing with fingers. The artificial bone material is put into the inside of the throat section through the funnel section, and the discharge part of the throat section is brought near to the gap part of the bone to fill the gap part with the artificial bone material. If the inside of the throat section is blocked with the artificial bone material, pressing the throat section with fingers deforms the throat section, giving an effect like disentangling the throat section with fingers and releasing the blockage of internal walls of the throat section. This facilitates the filling of the artificial bone material during surgery, ensuring reliable filling work and shortened surgery time. |
