The invention relates to the field of medical instruments, in particular to a visual lumbar vertebra screw turning device. The visual lumbar vertebra screw turning device comprises a rotating cylinder, an outer cylinder and a movable structure. Scale marks are arranged on the outer peripheral face of the outer cylinder in the axis direction of the outer cylinder, a strip-shaped hole is formed in the outer peripheral face of the outer cylinder in the axis direction of the outer cylinder, and the strip-shaped hole is adjacent to the scale marks. The movable structure comprises a movable block and an abutting block, and the movable block is connected with the abutting block; the movable block is matched with the strip-shaped hole in a sliding mode, and the abutting block abuts against the outer wall of the second subsection; the abutting block is used for driving the movable block to move relative to the strip-shaped hole when the second section rotates, so that the stroke of the lumbar vertebra screw under the driving action of the first section is shown through the scale marks. According to the visual lumbar screw turning device, the movement stroke of the lumbar screw can be determined according to the movement stroke of the movable block relative to the scale marks, and therefore the screwing-in amount of the lumbar screw can be determined.
Description
technical field [0001] The present application relates to the field of medical devices, in particular to a visual lumbar screw reversing device. Background technique [0002] At present, when the lumbar spine is diseased or injured, in order to treat or further recover, the surgery needs to perform fixed surgery on the lumbar spine, and it is common to install lumbar screws. In the prior art, when installing the lumbar screw, it is necessary to turn the lumbar screw through a U-turn device to fix the lumbar screw, but during the twisting process, the amount of screwing in of the lumbar screw cannot be determined. Contents of the invention [0003] The present application provides a visual lumbar screw head-turning device to improve the above problems. [0004] The present invention is specifically as follows: [0005] A visible lumbar screw head-turning device, which includes a rotating cylinder, an outer cylinder and a movable structure; [0006] The rotary drum includ...
