The present invention relates to a spinal fusion cage which is inserted between vertebral bodies in a state where the cage has the lowest height, is height-adjustable in the inserted state, and can simplify a height adjustment mechanism, thus making it possible to replace cages having heights in a certain range by a single cage. Therefore, manufacturers can reduce product groups that need to be produced, and can also reduce product stock. Further, in contrast to the conventional cages having predetermined heights at regular intervals, the height of the inventive cage can be linearly adjusted according to the distance between the vertebral bodies of a patient, and thus a surgery can be performed using the cage adjusted to an optimum height according to the patient's condition.

Height-adjustable spinal fusion cage

The present disclosure relates to an intervertebral fusion cage configured to be inserted between vertebral bodies in a lowest state and improving fixation by bone screws inserted through end plates. The intervertebral fusion cage of the present disclosure may replace intervertebral fusion cages having heights within a given range. Therefore, manufacturers may reduce the number of product groups and the amount of inventory. In addition, because the height of the intervertebral fusion cage of the present disclosure is linearly adjustable according to the distance between vertebral bodies of patients unlike conventional intervertebral fusion cages having heights preset at predetermined intervals, surgery may be performed at an optimal height according to the conditions of patients.

Height-adjustable intervertebral fusion cage

The present invention relates to a spinal fusion cage which is inserted between vertebral bodies with the lowest height and is height-adjustable in the inserted state, whereby cages having heights within a predetermined range can be replaced by a single cage. Therefore, manufacturers can reduce product groups that need to be produced, and can also reduce product stock. Further, in contrast to the conventional cages having predetermined heights at regular intervals, the height of the inventive cage can be linearly adjusted according to the distance between the vertebral bodies of a patient, and thus a surgery can be performed using the cage adjusted to an optimum height according to the patient's condition.

The present invention provides an oblique spinal fusion cage capable of executing a surgery even when there are a psoas muscle and a peritoneum along an operation route, which is performed in a direction inclined from a flank. The oblique spinal fusion cage has a curved shape as a whole so as to be stably seated in a space between vertebral bodies irrespective of a skill level of an operator, thereby preventing a medical accident that may occur in the patient.

The present invention provides a cage holder for a spinal fusion cage which is mounted on the spinal fusion cage, thereby allowing the spinal fusion cage to be stably inserted between vertebral bodies. The cage holder may be engaged with the spinal fusion cage to insert the spinal fusion cage between the vertebral bodies at the lowest height, and may be reliably separated from the spinal fusion cage after the surgery. In addition, when mounting the cage holder on a height adjustable spinal fusion cage, the cage holder may visually indicate an amount of change in the height of the spinal fusion cage.

Cage holder for spinal fusion cage

The present invention provides a spinal fusion cage that can be inserted between vertebral bodies at the lowest height, and the height thereof may be adjusted with being inserted, such that cages having different heights within a certain range may be replaced by one cage. Therefore, the number of product groups that should be produced is reduced and the amount in stock is also decreased on the manufacturer. In addition, unlike the cage having a predetermined height at a constant interval in the prior art, the height of the spinal fusion cage is linearly adjusted according to a spacing between vertebral bodies of a patient, such that the surgery may be performed at the optimal height according to spinal conditions of the patient.
