Embodiment 1

[0029] Such as Figure 1 to Figure 5 As shown, a fence-shaped bone cement spinal fusion device adopting balloon molding includes a balloon system and an endoscope system, and the balloon system adopted in the present invention includes an outer fence-shaped balloon 5 and a central butterfly-shaped balloon 6. Among them, the shape of the outer fence-shaped balloon 5 is irregular oval, the shape of the central butterfly-shaped balloon 5 is irregular butterfly-shaped, and the outer fence-shaped balloon 5 is placed in the central butterfly-shaped ball The outside of the capsule 6 needs to be fixedly connected by 8 balloon connecting bands 7 between the two, so that the two become a fixed balloon device, and finally the outer fence type balloon 5, the central butterfly balloon 6 and the balloon After the balloon connecting band 7 is fixedly connected, the whole scales into the balloon sleeve 1. Through the fixing effect of the balloon connecting band 7, it can effectively prevent t...

Embodiment 2

[0034] Such as Figure 1 to Figure 3As shown, by adopting the spinal fusion device made in the above-mentioned embodiment 1 to implement the intervertebral fusion operation, the balloon system of the present invention, when not in use, the outer fence-shaped balloon 5, the central butterfly-shaped balloon 6 and the balloon After the connecting band 7 is fixedly connected, the whole is zoomed into the balloon sleeve 1, such as figure 1 Shown; After utilizing cannula handle 2 to push forward, the balloon system of the present invention becomes shriveled contraction state, and this moment has not yet inflated, as figure 2 As shown; before the release of the balloon, the balloon can be implanted or explanted between the two vertebral body endplates through the minimally invasive incision through the endoscope system. After the butterfly balloon 6 is inflated, see the state image 3 , can make the two balloons inflate and expand, and then stretch the intervertebral endplate, rai...

Abstract

The invention provides a fence type bone cement spine fusion device formed by a balloon. The device comprises a balloon system and an endoscope system, wherein the outer side fence type balloon of the balloon system is fixedly connected with a central butterfly-shaped balloon through a balloon connecting belt, the outer side fence type balloon, the central butterfly-shaped balloon and the balloon connecting belt are fixedly connected to be integrally contracted into a balloon bushing, independent balloon inflating interfaces are designed at the rear end of the outer side fence type balloon and the rear end of the central butterfly-shaped balloon respectively, a bushing grab handle is arranged on the central butterfly-shaped balloon inflating interface and the outer side fence type balloon inflating interface in a sleeving mode, the endoscope system comprises a working sheath and an endoscope, the endoscope is matched and connected with the working sheath in a sleeving manner, the balloon bushing is matched and connected with an instrument channel of the endoscope in a sleeving manner, and the bushing grab handle is exposed out of the interface of the instrument channel. According to the invention, a surgical incision can be effectively reduced, and spinal column injury caused by application of an external fixation system is avoided.

Description

technical field [0001] The invention relates to the technical field of intervertebral fusion, in particular to a fence-type bone cement spinal fusion device formed by a balloon. Background technique [0002] In recent years, the proportion of spinal fusion in surgical operations has steadily increased. Most of the surgical procedures are performed using fusion cages. Specifically, after the fusion cage is embedded and fixed to reach the required intervertebral space, the bone graft is placed in the bone graft cavity. In the past, spinal fusion surgery needed to be completed with a fusion cage and an external fixation system, and the height of the intervertebral space was raised through external support, so as to restore the physiological structure of the spine. [0003] At present, most fusion cages on the market are of fixed size or expandable type. The height of fusion cages is often higher than that of the intervertebral space, and their volume is large. The original spi...
