Contractible minimally invasive intervertebral forming and fusing device

Abstract

The invention discloses a contractible minimally invasive intervertebral forming and fusing device. The contractible minimally invasive intervertebral forming and fusing device comprises a contractible supporting part, the supporting part comprises a side wall surrounding the periphery, an upper top face located at the upper end of the side wall and a lower bottom face located at the lower end ofthe side wall, and multiple partition plates are arranged in the inner space defined by the side wall and partition the inner space into multiple longitudinal chambers; through holes are formed in a part of partition plates, and the chambers are communicated to form one or more through regions; an opening part communicated with a guide pipe is formed in the side wall of the supporting part; the partition plate with the through holes is at least arranged in the through regions so that the guide pipe can be communicated with the through regions through the opening part of the side wall of the supporting part. The device can be compressed into a small size and enters the portion between any two adjacent centra of the human body through a small incision in minimally invasive surgery, after unfolding, the honeycomb supporting part is high in supporting performance and stable, the bone grafting area and space are increased, surgery operation time is short, and the contractible minimally invasive intervertebral forming and fusing device is simple and convenient.

Description

technical field

[0001] The invention relates to a compressible minimally invasive intervertebral fusion device. Background technique

[0002] With the increasing number of patients with spinal degenerative diseases, researchers have invented some artificial intervertebral discs or alternative intervertebral supports or fillers after long-term research. However, it is difficult for the existing intervertebral fusion device to be implanted in the intervertebral space in the minimally invasive surgical channel and maintain the stable support of the intervertebral space. It is often necessary to combine the posterior nail rod screw fixation system, and implant between the vertebral body endplates. In this solution, both the front and back of the vertebral body need to be fixed, the workload is heavy, the operation time is long, the operation area is large, the trauma is large, the cost is high, and the patient needs a long recovery period after operation. It is not conducive to...

Examples

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Such as figure 1 As shown, the shrinkable and expandable minimally invasive intervertebral fusion device of the present invention includes a catheter 2 and a support member 1 connected through the catheter. The support member 1 communicates with the conduit 2 through the mouth 111 opened on the side wall 11 .

[0025] The support member 1 includes a surrounding side wall 11, an upper top surface at the upper and lower ends of the side wall (the upper top surface is not shown in the internal structure diagram) and a lower bottom surface 12, and the inner space surrounded by the side wall 11 has A plurality of vertical partitions 13, the side walls and partitions are integrally formed, an...
