Embodiment 1

[0052] like Figure 1 to Figure 6 As shown, the specific solution given in this embodiment is that the fused main board and cover board are flat plates.

Embodiment 2

[0054] like Figure 6 to Figure 9 As shown, this embodiment provides a specific solution. The fusion main board and cover board are boards with a porous structure.

[0055] In addition, the width of the bottom plate 4 is required to be smaller than the distance between the two anti-loosening bolts 2;

Embodiment 3

[0057] like Figure 1 to Figure 6 As shown, the present embodiment provides a specific scheme that the bottom plate 4 is integrally formed with the bottom of one fusion side plate 30, and the bottom of the other fusion side plate 30 is provided with a slot 41 for inserting the bottom plate 4; there are also slots 41 on the slot 41. Lock nuts for locking the bottom plate 4.

Abstract

The invention discloses an interspinous fusion device which comprises a cover plate, anti-falling bolt pieces, a fusion main plate and a bottom plate. The fusion main plate comprises two fusion side plates which are oppositely arranged, and the two fusion side plates are respectively used for being arranged on both sides of a spinous process; the anti-falling bolt pieces penetrate through the fusion side plates to be fixed to the spinous process; a fusion cavity for filling bone blocks is formed between the two fusion side plates; the cover plate covers the fusion cavity and is fixedly connected with the upper parts of the two fusion side plates; and the bottom plate is arranged at the bottoms of the two fusion side plates and is connected with the two fusion side plates. The invention provides the interspinous fusion device. By the device, a minimally invasive surgery can be implemented on a patient suffering from instability of lumbar vertebrae and mild lumbar spondylolisthesis non-nervous symptoms, the spinous process is rapidly fixed and fused, and the surgery efficiency and safety are improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an interspinous process fusion device. Background technique [0002] With the development of spinal minimally invasive technology, spinal surgery is becoming more and more refined and minimally invasive, so that patients' complications and surgical risks are getting smaller and smaller. For patients with lumbar instability and mild spondylolisthesis without neurological symptoms, minimally invasive oblique lateral interbody fusion (OLIF) has become a minimally invasive spinal surgery hotspot for the treatment of such diseases. It utilizes the natural gap between the retroperitoneal abdominal aorta and the anterior edge of the psoas major, and is compatible with the traditional minimally invasive surgical methods of extreme lateral interbody fusion (XLIF) and lateral interbody fusion. Compared with direct lateral interbody fusion (DLIF), it can better protect the psoas major mu...
