Description

Technical Field

[0001] The present invention relates to the technical field of fracture reduction, and more specifically, to a spinal vertebral fracture reducer. Background Art

[0002] Spinal fractures often occur in the thoracic and lumbar regions, often caused by direct or indirect violence. For fractured vertebrae, the treatment is usually to restore the fracture site or replace it with a filler. When performing the above operations, it is usually necessary to use a reducer to reduce the size of the surgical incision.

[0003] However, most of the existing vertebral fracture reducers are simple instruments cast in one piece of metal material. When reducers with different operating angles are needed, different reducers need to be used. In addition, since the surface of the reducer is smooth, it is easy to slip when operating the filling piece or reducing the bone, which can easily cause the force to deviate and affect the nerve root, thereby reducing the effectiveness of the device.

[0012] The principle and beneficial effects of this technical solution:

[0013] (1) The adjustment component provided in the present invention can adjust the angle between the fixed plate and the hook plate, thereby saving the time of medical staff in changing tools. At the same time, the fixed plate and the hook plate can be adjusted to a colinear position, which is convenient for cleaning the rough surfaces of the fixed plate and the hook plate, thereby maintaining the cleanliness of the tool and the friction coefficient. When it is necessary to increase the angle between the fixed plate and the hook plate, the reel is started, and the output end of the reel will pull the pull rope, so that the connecting block connected to the free end of the pull rope pulls the traction belt. At this time, the traction belt will rotate the rotating shaft around which it is arranged, and the transmitter provided on the outside of the rotating shaft will rotate synchronously with the rotating shaft. The user can determine the current angle state of the tool through the sensor button corresponding to different angles of the transmitter. After adjusting to the appropriate angle, the reel is stopped. At this time, the coil spring connected between the other rotating shaft and the connecting frame will jointly position the hook plate with the reel; and when it is necessary to reduce the angle between the fixed plate and the hook plate, the reel releases the traction on the pull rope, and the coil spring will drive the hook plate close to the connecting frame, and finally reset the connecting frame.

[0014] (2) The lighting assembly provided in the present invention can enhance the clarity of operation during the use of the device and help the user to perform precise operations. When lighting is needed, the micro flashlight can be directly turned on, and the lighting end of the micro flashlight will illuminate the operating environment through the light-transmitting hole. When the micro flashlight needs to be removed for charging, the micro flashlight can be directly moved down along the card slot, and the micro flashlight can compress the first spring through the support plate, so that the first spring is compressed until the support plate rotates to a horizontal position. At this time, the micro flashlight can be removed by moving it outward along the side groove direction for charging.

[0015] (3) The handle provided in the present invention can improve the user's operating accuracy of the tool. At the same time, when the handle needs to be removed, the handle can be removed. When the handle needs to be removed, the button is pressed upward, and the button will compress the second spring through the limit plate. At the same time, the support plate connected to the top of the limit plate will lift up the two support blocks, so that the positioning plate connected to the top of the support block moves along the inclined groove. At this time, the positioning column connected to the opposite side of the positioning plate will slide along the positioning groove on the vertical plate at the same time until the positioning column is completely moved out of the positioning groove. At this time, the connecting frame can be lifted upward to make the vertical plate at the bottom of the connecting frame detach from the handle. BRIEF DESCRIPTION OF THE DRAWINGS
