Universal centrum repositor used in orthopedic spinal surgery

Abstract

The invention relates to the technical field of orthopedics, and discloses a universal centrum repositor used in orthopedic spinal surgery. The universal centrum repositor comprises a bearing plate, wherein the front and back of the bearing plate are slidably connected with supporting walking mechanisms, the upper surface of the bearing plate is fixedly provided with a motor, the output end of the motor is fixedly connected with a driving bevel gear, and the two sides of the driving bevel gear are engaged with driven bevel gears. According to the universal centrum repositor used in the orthopedic spinal surgery, through the arrangement of the bearing plate, the motor, the driving bevel gear, the driven bevel gears, a driving motor and other structures, an adjusting lead screw is rotated to enable a pull rope to move, and clamping or separation of an upper rotating block and a lower transmission block is achieved; and a connecting plate is pulled to adjust the clamping angle of the upper rotating block and the lower transmission block, and therefore, width and height adjustment of the universal centrum repositor before use can be achieved through a single motor; and clamping reposition of the centrum can be achieved through matched use of a lead screw.

Description

technical field [0001] The invention relates to the technical field of orthopedics, in particular to a vertebral body universal reducer used in orthopedic spinal surgery. Background technique [0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. , the spectrum of orthopedic injuries has changed significantly, for example, bone and joint tuberculosis, osteomyelitis, polio and other diseases have decreased significantly, trauma caused by traffic accidents has increased significantly, and the spectrum of orthopedic injuries has changed, which requires orthopedics to keep pace with the times In recent years, with the development and progress of science and technology, orthopedics has made great progress in diagnosis and treatment. The establishment and deve...

Problems solved by technology

[0003] Vertebral body resetters are often used in some orthopedic spine operations. Commonly used vertebral body resetters are mostly divided into two types: manual adjustment and motor automatic adjustment. Among them, the manually adjusted vertebral body resetter not only adjusts the efficiency during operation It is relatively low and increases the labor intensity of medical staff, which is not conducive to surgical operations. Although the adjustment of the vertebral body resetter with automatic motor adjustment is relatively fast, it needs to achieve angle and height adjustments in different directions, resulting in internal The number of electrical drive equipment required is large, the structure is more complicated, and the cost is higher, which leads to inconvenient maintenance in the later period. For this reason, a vertebral body universal resetter used in orthopedic spinal surgery is proposed.
