Description

Correction device for spinal deformity surgery

Technical field

The invention relates to the technical field of medical instruments, in particular to a spinal deformity surgical correction device. the

Background technique

At present, domestic spinal correction technology is mainly carried out through deformity-related segmental pedicle screws and connecting rods. Since spinal deformity surgery is a high-risk operation, the operation time of domestic commonly used techniques is long, and segmental pedicle screws and connecting rods are used. The technique is easy to injure and the surrounding related tissues have many complications. The use of force sensors and multi-stage simultaneous correction devices can reduce surgical complications and shorten operation time. With the rapid development of material science, sensor technology and biomechanics, various medical devices and equipment emerge in an endless stream. Force sensors have begun to be widely used. Doctors can judge the degree of spinal deformity correction based on the mechanical signals of multiple segments displayed by auxiliary devices. and whether it will damage the bone. In conventional surgery, it is necessary to implant pedicle screws and connect connecting rods in the vertebral body of the deformity-related segment, and rely on manual lifting and rotation to complete the correction of the deformity. However, this process cannot guarantee the complete correction of the deformity. Damage to bone and other soft tissues, so a spinal deformity correction device is needed to ensure the thoroughness of spinal deformity correction while minimizing the possibility of other tissue damage. the

The crossbeam is arranged in sequence and slides into multiple longitudinal horizontal groove sliding sleeves. The connecting plate is fixed on the plane of each longitudinal horizontal groove sliding sleeve, and the connecting plate is fixed at an angle of 90 degrees to the crossbeam. Horizontal horizontal groove sliding sleeve, the horizontal horizontal groove sliding sleeve slides into the horizontal square slider with multiple vertical positioning holes; one end of the horizontal square slider is inserted into the horizontal cylinder flange to fix, and the cylindrical flange plane end is fixed Connect the vertical vertical groove sliding sleeve, the vertical groove sliding sleeve slides and snaps into the vertical square sliding rod with multiple horizontal positioning holes; one end of the vertical square sliding rod is inserted into the vertical cylinder flange to fix, and the vertical cylinder The flat end of the body flange is fixedly connected to the lower horizontal horizontal groove sliding sleeve, and the lower horizontal horizontal groove sliding sleeve slides and snaps into the lower horizontal square slider with multiple vertical positioning holes, and is positioned and fixed by the vertical positioning holes; The horizontal square slider is parallel to the horizontal square slider; the horizontal vertebral body connecting rod is fixed on the lower horizontal horizontal groove sliding sleeve, the horizontal vertebral body connecting rod is parallel to the horizontal square sliding rod, the connecting hook is fixed at one end of the vertebral body connecting rod, and the vertebral body is connected The middle part of the rod is inserted into the pressure monitoring box. the

The working principle of the present invention is: the door-shaped frame formed by the bedside support bar and the crossbeam is fixedly connected with the sliding lifting guide rail system on both sides of the operating bed, and a plurality of longitudinal horizontal groove sliding sleeves can slide on the crossbeam, and are controlled by the crossbeam. The vertical positioning hole is fixed after positioning, the horizontal horizontal groove sliding sleeve is fixedly connected with the longitudinal horizontal groove sliding sleeve, the horizontal square sliding rod slides in the horizontal horizontal groove sliding sleeve, and is positioned by the vertical positioning hole on the square sliding rod Rear fixed; the vertical square slide bar can slide in the vertical vertical groove sliding sleeve, and fixed by the horizontal positioning hole on the square slide bar; the lower horizontal square slide bar can slide in the lower horizontal horizontal groove sliding sleeve, and It is positioned and fixed by the vertical positioning hole on the lower horizontal square sliding rod; when the present invention is used, multiple spinal deformity correction devices installed on both sides of the operating bed are used symmetrically in pairs, and multiple vertebral body connecting rods are paired and horizontally opposed. The connecting hooks on the connecting rods of the vertebral body correspond to each other. After the pedicle screw is placed, the patient is located in the horizontally opposite space of the connecting rods of the vertebral body. The rod and the lower horizontal square sliding rod move and push and pull in all directions in space. After the connecting hook is connected with the pedicle screw on the patient's spine, then the longitudinal horizontal groove sliding sleeve, the horizontal square sliding rod, The vertical square slide bar and the lower horizontal square slide bar are respectively moved or pushed and pulled for manual pressure, so as to correct the spinal deformity of the patient. The pressure monitoring box can constantly monitor the force and moment of the connecting hook at the end of the connecting rod of the vertebral body, and can give an alarm before the damage to the bone, thereby preventing the occurrence of bone damage. the

The invention can correct the patient's deformed spine in an all-round way during the operation, monitor the size of the orthopedic force constantly, prevent the occurrence of bone damage, and is flexible and convenient to operate, thus achieving the purpose of the invention. the
