Abstract

The invention provides a lamina distraction device, which comprises: a distraction main body with a first distraction part; a moving assembly including a connecting piece and a flipping piece, the position of the first end of the connecting piece is adjustable The flipping part is hinged to the second end of the connecting part, and the flipping part has a second stretching part set corresponding to the first stretching part; the driving part is driven and connected with the flipping part to drive the flipping part Spread the body to move and flip. The technical solution provided by the present application can solve the problem in the prior art that the spinous process cannot be moved back while the gap is opened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lamina distraction device. Background technique [0002] Spinal laminoplasty is a surgical method in which one or both sides of the lamina are incised, and the lamina is shifted posterolaterally to expand the spinal canal. Conditions such as ossification of the posterior longitudinal ligament and multisegmental cervical spondylotic myelopathy. [0003] Spinal laminoplasty opens the lamina into two "door" shapes, which can expand the sagittal diameter of the spinal canal and conform to the cylindrical structure of the spine, so that the spinal cord can be evenly decompressed. In clinical practice, after the bilateral lamina is exposed through the posterior approach of the cervical spine, all the spinous processes of the "gate" are cut off as planned, the lamina is clamped from the center from bottom to top, and the ligaments above and below the "gate" (including the...
