Medical engineering Background in the relevant art or science. Bone sutures are devices used in orthopedic surgery to treat injuries and conditions. They are useful for holding two pieces of bone together, such as joining fractured bone fragments or trimmed bone fragments. They can also be used to secure ligaments to bone, such as in tendon reconstruction surgery. Furthermore, they can be used to fix bones to control the growth of bone-forming plates in children. Osteogenesis plates are typically located at the ends of bones. In children, the osteogenesis plate can be divided into two regions based on bone growth: the central region and the marginal region. Growth in the central region causes bone elongation, while growth in the marginal region causes bone widening. The marginal region protrudes slightly from the plane of the surrounding bone. Growth of cells in both regions of the osteogenesis plate is necessary for bone to lengthen and enlarge in the appropriate proportions. Bone fixation surgery in children is used to control and correct bone length and deformities. This type of surgery can be divided into two types: temporary and permanent growth control. For temporary growth control, once the bone has grown to the desired shape after the initial fixation with bone sutures, a second surgery is required to remove the sutures. Surgical fixation of bone to control the growth of bone-forming plates in children can lead to several complications. These include: the metal suture pressing on the edge of the bone-forming plate, causing permanent cell death and preventing further growth; subsequent bone deformity; the suture becoming misaligned and piercing the center of the bone-forming plate, injuring and halting cell growth; the suture withdrawing from the bone due to insufficient fixation; and the suture fractureing due to inadequate strength. These complications are partly due to the design of conventional bone sutures. Traditional sutures have a straight central connecting rod, which may have sharp barbs protruding from the underside. When the suture is driven into the bone to prevent withdrawal, this rod presses on the raised edge of the osteoblast, causing permanent injury to the cells at the edge of the osteoblast. If the surgery aims only at temporary bone growth control, this can lead to subsequent problems. Furthermore, accurately centering the suture, ensuring its legs are evenly spaced from the osteoblast, is difficult due to the lack of a guiding device to aid in precise suture placement. The nature and purpose of the invention. Due to the aforementioned problems, a new type of bone suture was invented to reduce complications, make surgery more precise, and result in smaller incisions. Specifically, The lower surface of the connecting rod, which is the central part of the bone suture, is designed to be smooth and concave to prevent it from pressing down on the edges of the bone grafting plate. A mark indicates the appropriate depth of the suture insertion to prevent injury to the edges of the bone grafting plate from insertion too deeply or withdrawal of the suture from insertion too shallowly. The center of the bone graft has a hole for inserting a guide wire. During surgery, the center position of the bone graft plate can be determined by inserting the wire into the center, after verifying the position on an X-ray. Then, the suture is inserted through the hole of the bone suture along the guide wire, allowing for precise placement of the suture. To reinforce the bone suture connecting rod and to provide an anchor point for the bone suture holder for suture removal, a wider central section of the rod was designed with slanted extensions on both sides. When viewed in cross-section, this section forms a triangle. Having the attachment point concentrated only in the central area allows for easier removal of the bone suture holder by sliding it laterally over a shorter distance, resulting in a smaller incision. Extending from both ends of the connecting section of the bone suture, there are two protruding legs. The inner surface of these legs is smooth and parallel, while the outer surface has a wavy, ribbed appearance with inward and outward ridges along its entire length. The outer surface of this leg tapers slightly from the top down to the very end, becoming pointed. This tapering design, particularly on the outer surface, minimizes the width of the bone cavity surrounding the leg where the bone suture is inserted. As the bone suture expands due to bone growth, the ribs on this leg adhere more tightly to the bone, reducing the likelihood of suture withdrawal after surgery. Full disclosure of the invention. The bone suture is made of titanium and consists of two parts: the bridge and the leg. 1. Bridges are metal rods running transversely, with lengths ranging from 5 to 30 millimeters, widths from 2 to 6 millimeters, and heights from 3 to 8 millimeters. The top surface is straight (1), the bottom surface is flat and concave (2), there is a hole at the center for inserting a guide wire (cannulated hole) (3), the hole is sized from 1.2 to 2.0 millimeters, and in the middle of the weld pipe there is a widening section that extends diagonally to the sides (shelf) (4), when viewed in cross-section of this widening section on each side it forms a triangle. The ends of both connecting sections are notched at an angle with the lower angle point aligned with the highest point of the concave section of the lower surface (5). Both ends of this connecting piece will be attached to the leg section. 2. Legs are extensions from both ends of the connecting rod, with a length of 12 to 35 millimeters and a width of 2 to 6 millimeters. The top part is as wide as a connecting rod, and the section below gradually tapers. The inner surface of each leg is smooth and parallel to the outer surface, which has a wavy, ridged appearance that extends in and out almost the entire length and tapers slightly towards the end (6). The very end tapers down until it has a pointed shape (7). Brief description of the painting. Figure 1 shows the anterior aspect of the bone sutures.
