するようになっている。2. Description of the Related Art When an artificial ligament or an autologous ligament is used to reconstruct a damaged living ligament, staples have often been used to fix the reconstructed ligament. As shown in FIG. 12, the structure of the conventional staple is formed in a gate shape and includes a horizontal rod portion and a leg rod, and a projection is provided on the lower surface of the horizontal rod portion, or a chevron shape is formed on the outer surface of the leg rod. Some have a structure in which projections are protruded. The staple is driven into the bone at the end of the reconstructed ligament, and is fixed by sandwiching the reconstructed ligament between the horizontal rod and the surface of the bone.

や、ステープル固定部の痛みなどの問題点を生じる。However, the above-mentioned conventional staples fix the reconstructed ligaments with the compressive force between the horizontal rod of the staples and the bone surface, and thus the fixing force is weak. As shown in FIG. 13, two conventional staples are used to increase the fixing force of the staple, the reconstructed ligament is first fixed with one staple, the reconstructed ligament is turned back, and the second staple is driven close to the first staple. There was a double stapling method. In this method, if the staples do not come close to each other, the effect of increasing the fixing force cannot be exhibited.On the other hand, if the staples come close to each other, the staples that hold the staples to the bone come into close proximity to each other, so that the fixing force to the bone is reduced. Has the disadvantage of becoming weaker. This not only weakens the initial fixing force of the staple, but also causes problems such as a decrease in long-term holding power to the bone and a pain in the staple fixing portion.

For this purpose, it is conceivable to drive two staples at an angle to each other.However, when a conventional staple is driven with an inclination, the lower surface of the horizontal rod portion of the staple does not adhere to the bone and a gap is opened, so the ligament However, there was a drawback that the fixing force of the rubber was reduced. Even when the bone is not flat but spherical, the lower surface of the horizontal rod portion of the staple has a gap with the bone, and there is a disadvantage that the fixing force of the ligament is reduced. Conventionally, there have been some staples which have chevron-shaped projections on both leg rods to increase the fixing force to the bone, but have not obtained a long-term fixing force to the bone.

ることを特徴とする。The technical measures taken by the present invention to attain the above object are as follows. When performing the double stapling method using two staples as shown in FIG. In order to make the horizontal rods of the staples close to each other and to allow the horizontal rods of the staple to come close to each other, one of the staples has a structure in which a side surface of the horizontal rod of the staple is projected outward. If one of the staples is slanted and driven, the legs of the two staples can be separated from each other. For this reason, the length of the staple leg is changed so that the staple can be driven with an inclination. However, when the staples are slanted and driven, there is a gap between the horizontal staple and the bone surface with the conventional staples. It is characterized in that the leg is inclined linearly or in a curved shape from the leg toward the other leg. When a complementary plate having a linear or curved inclined surface or a curved plate as a whole is sandwiched between the staple and the bone, the surface in close contact with the bone increases, and the fixing force of the ligament increases. Further, in order to increase the stability of the supplementary plate, the place where the horizontal rod of the staple hits is formed in a concave shape. In order to make it difficult for the staples to come out of the bone and to make it easier to adhere to the bone,
A ceramic coating process is additionally provided on the outer peripheral surfaces of the two leg rods as rough mesh-like rough surfaces or lattice grooves.

The overhang of the overhang portion of the staple horizontal rod portion is about the same as or greater than the width of the staple horizontal rod portion, and similarly, the width of the complementary plate is at least 2-3 times the width of the staple horizontal rod portion. The same effect can be obtained even if the overhangs of the horizontal rod are on both sides of the horizontal rod. The length of the two leg rods of the inclined driving staple or the inclination angle of the staple having an inclined surface on the lower surface of the horizontal rod portion can be set arbitrarily, for example, 5 degrees or 10 degrees. Also, the curved shape of the lower surface of the horizontal rod portion can be arbitrarily set according to the shape of the bone. This is the same for the complementary plate. These staples can be used alone or in combination, and the fixing force is increased as compared with the conventional staples.
The rough surface or the lattice-shaped groove of the staple body may be two or three on the outer peripheral surface of the two legs.

る。FIGS. 9 to 11 show an embodiment of the invention according to claims 5 and 6, and FIGS. 9 and 10 show a fine mesh-shaped outer peripheral surface of both leg rods 1b and 1c in the staple body 1. FIG. It is made by processing the rough surface of irregularities and the lattice-like groove, and since there is no projection shape on the leg rod part when driving, the resistance with bone is reduced, the wear coefficient with bone is hard to rise and it is difficult to remove When the bone tissue enters into the concave portion or the groove portion 8 of the rough surface, the fixing strength of the staple with the bone increases. FIG. 11 shows a cross section in which a ceramic coating (for example, hydroxyapatite coating) 9 having an affinity for bone tissue is applied to the surfaces of the two legs 1b and 1c formed in the rough surface and the groove 8 described above. As a result, the outer surfaces of the legs 1b and 1c are flush,
Thereby, the resistance at the time of driving into the bone is reduced, and after the driving, the ceramic coating is integrated with the bone tissue, thereby contributing to preventing the staple from coming off. When the present invention (claims 5 and 6) is further added to claims 1 to 3, the fixing force and the fixing force of the staple increase.

A staple with a protrusion or a complementary plate can be obtained by enlarging an overhanging portion or increasing the width of the complementary plate. Compared to the staples with the conventional structure, not only the surface that holds the reconstructed ligament becomes wider, but also the degree of adhesion to the bone increases, the fixation force of the reconstructed ligament increases, and bone destruction can be reduced. Even if it is applied, the staple is hard to stick, so that the initial driving state can be maintained.

け、グラ付き防止に貢献する。According to the staple for fixing a ligament according to the present invention, the contact area for holding the reconstructed ligament is wider than that of the conventional staple, and the fixing force of the reconstructed ligament is increased. Further, even if the staple is driven in an inclined manner to the bone by the configuration of the second aspect, the straight or curved inclined surfaces on the lower surfaces of the horizontal rod portion and the overhanging portion can be in close contact with the bone tissue widely, which has occurred in the case of the conventional staple. The generation of the gap can be reliably eliminated. In the case of the configuration described in claim 3, it is possible to strike the bone accurately at an angle by one leg shortening. In the case of the configuration as set forth in claims 1 to 3, even if the double stapling method is fixed, two staples are projected by the angle of the horizontal rod portion of one of the staples, and the staples are driven at an angle. The two staple legs can be separated from each other while keeping the horizontal rods close to each other, and bone destruction can be minimized. According to the configuration of the fourth aspect, the linear or curved inclined surface on the lower surface of the complement plate can be in close contact with the bone tissue widely, and the generation of the gap generated in the case of the conventional staple can be surely eliminated. In the case of the configuration according to claim 5 and claim 6, damage to the bone tissue can be implanted to a minimum, and after the implantation, the bone tissue enters into the uneven rough surface or the lattice-like groove or the ceramic coating. The layers and bones are integrated, helping to remove staples and prevent sticking.
