Vertebral body universal repositor used in orthopedic spinal surgery

Abstract

The invention discloses a universal centrum repositor used in an orthopedic spinal operation, and relates to the technical field of medical instruments, the universal centrum repositor comprises a supporting column, a movable sleeving column and a transverse adjusting assembly are arranged in the supporting column, the movable sleeving column is arranged on the top surface of a top plate, and the transverse adjusting assembly is arranged on the top surface of the top plate; the movable sleeving column is arranged to be used for transversely adjusting the clamping assembly, the clamping assembly is arranged below the transverse adjusting assembly, the clamping assembly is arranged to be used for clamping the vertebral body of a patient, and by arranging the clamping assembly, when the vertebral body is clamped, a clamping frame only needs to be aligned to the vertebra needing to be clamped, and the vertebral body can be clamped through the clamping assembly; and then the threaded sleeve is held to rotate clockwise, so that the two movable blocks can be driven to move oppositely in the fixed connecting frame, and screwing can be stopped until the clamping frame can stably clamp the centrum needing to be clamped, so that the overall clamping convenience of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vertebral body universal reducer used in orthopedic spine 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 shape and function of this system. The spine consists of vertebrae and intervertebral discs. , is a very soft and movable structure. With the movement load of the body, the shape of the spine can change considerably. The movement of the spine depends on the integrity of the intervertebral disc and the harmony between the articular processes of the related vertebrae. When the spine is injured, it needs to be When performing repair surgery, a vertebral body universal reducer is usually used for auxiliary surgery to ensure the normal impleme...
