6, JP-A-3-128061) These cements are kneaded with a hardening liquid to form a paste,
A method of applying directly to the affected area using a hand or a spatula or injecting into the affected area using an injector is used. In particular, the latter method allows deep and small injections into the affected area,
This is a preferable method because the cement after the operation is not dispersed in the body and the burden on the patient is small.

ペーストの粘度が高いからである。However, since there is no suitable injector at present, a commercially available injector is used. When using a commercially available syringe,
First, the piston of the syringe is pulled out, cement paste is put into the tubular portion, the piston is attached, and this is pushed to inject the cement paste into the affected area. At the time of this operation, the needle is removed from the beginning. Not using a needle
This is because the paste has a high viscosity.

大きくなるとの問題点があった。However, with the method using a syringe, the cement paste cannot be injected into the affected area at a deep location because the length of the discharge area is short. Moreover, since the cement paste is injected into the cement injector from the piston insertion port, the paste adheres to the wall of the storage part, and when the piston is inserted, the piston does not move smoothly. . If such a condition is reached, the operation will take a long time and the burden on the patient will increase.

況によっても異なるが2〜100cc程度である。In the present invention, the cement injection section and the cement storage section are in principle cylindrical bodies. However, an elliptic cylinder or a prism can be used in the range where the operation of the piston portion when the cement paste is injected into the affected area is smoothly performed. The volume of the cement storage portion is about 2 to 100 cc although it varies depending on the condition of the affected area.

出口は1個とは限らない。In the present invention, the cement discharge portion may have a cylindrical shape, a truncated cone shape with a narrowed tip side, or a shape similar to these. Also, the cement discharge part does not need to be integrally joined to the main body of the cement injection part,
It can be removable. In that case, the cement discharge part can be made to have a sufficient length at the time of manufacture, and can be cut to a length suitable for injecting the cement paste into the affected part during surgery. Although the cement discharge part is attached to the central part of the cement injection part in FIG. 1, it is not necessarily the central part and can be attached to any position. The discharge port 12 of the cement paste does not necessarily need to be at the forefront of the discharge part, and may be located on the side surface of the cement discharge part as shown in FIG. 3 or FIG. Further, the number of discharge ports is not limited to one.
