Abstract

The invention discloses a trial mold of an expandable intervertebral fusion device, which belongs to the field of intervertebral surgical instruments, and comprises a trial mold body and a fixing tube. It is set and screwed to the adjustment table. The test mold body includes two test modules. The test modules are slidably connected to the adjustment table. The adjacent side of the two test modules is provided with a guide surface that is in contact with the adjustment rod. The two guide surfaces are symmetrical. Set and tilt from one end close to the adjustment table to one end far away from the adjustment table. The application has the effect of improving the fitting degree of the size of the cage and the space between the two vertebral bodies.

Description

A trial model of an expandable intervertebral cage technical field [0001] The present invention relates to the field of intervertebral surgical instruments, in particular to a trial model of an expandable intervertebral cage. Background technique [0002] Intervertebral surgery is a common surgical operation for the treatment of lumbar spine diseases, such as intervertebral disc disease, lumbar instability, etc., These diseases are more common in middle-aged and elderly people, but as the sedentary problem in society becomes more and more serious, lumbar spine diseases tend to be younger. This treatment of lumbar spine disease becomes particularly critical. Spinal fusion is a kind of intervertebral surgery, and spinal fusion needs to use intervertebral cage, during operation, intervertebral fusion The articulator is implanted between the vertebral bodies of the spine to maintain the space between the two vertebral bodies for subsequent rehabilitation. In the process ...
