Guide module having oblique installation pins

A guide module having oblique installation pins, the guide module comprising:

• a first installation pin unit comprising a first pin and a second pin;
• a second installation pin unit comprising a third pin and a fourth pin;
• a reposition guide unit configured to be in direct contact with an aligned bone having an osteotomy site,
• wherein,
• the reposition guide unit is configured to be in direct contact with both one side and an opposite side of the aligned bone with respect to the osteotomy site, and
• the reposition guide unit has a first reposition hole with a first central reposition hole axis, a second reposition hole with a second central reposition hole axis, a third reposition hole with a third central reposition hole axis, and a fourth reposition hole with a fourth central reposition hole axis;
• and
• a compression guide unit disposed adjacent to the reposition guide unit,
• wherein the compression guide unit has a first compression hole with a first central compression hole axis, a second compression hole with a second central compression hole axis, a third compression hole with a third central compression hole axis, and a fourth compression hole with a fourth central compression hole axis,
• wherein,
• the first pin is configured to simultaneously pass through the first reposition hole, the first compression hole, and a portion of the aligned bone,
• the second pin is configured to simultaneously pass through the second reposition hole, the second compression hole, and another portion of the aligned bone,
• the third pin is configured to simultaneously pass through the third reposition hole, the third compression hole, and another portion of the aligned bone,
• the fourth pin is configured to simultaneously pass through the fourth reposition hole, the fourth compression hole, and another portion of the aligned bone,
• the first pin and the second pin are located on the one side with respect to the osteotomy site,
• the second pin is located closer to the osteotomy site than the first pin,
• the third pin and the fourth pin are located on the opposite side with respect to the osteotomy site, and
• the first central reposition hole axis is spaced apart at a predetermined distance from the first central compression hole axis such that the first pin is tilted with respect to the first central compression hole axis when the first pin passes through the first reposition hole and the first compression hole,
• the second central reposition hole axis is spaced apart at a predetermined distance from the second central compression hole axis such that the second pin is tilted with respect to the second central compression hole axis when the second pin passes through the second reposition hole and the second compression hole,
• the third central reposition hole axis is spaced apart at a predetermined distance from the third central compression hole axis such that the third pin is tilted with respect to the third central compression hole axis when the third pin passes through the third reposition hole and the third compression hole,
• the fourth central reposition hole axis is spaced apart at a predetermined distance from the fourth central compression hole axis such that the fourth pin is tilted with respect to the fourth central compression hole axis when the fourth pin passes through the fourth reposition hole and the fourth compression hole.
