Abstract

The invention discloses a fence-type endoscopic fusion device using absorbable materials, which includes an endoscope and a fusion assembly. The fusion assembly includes a balloon assembly, a bone cement input device and a bone graft assembly. The balloon assembly includes a balloon insertion assembly, Absorbable outer balloon and inner balloon, the bone graft assembly includes a pressurized bone graft funnel and a pressurized bone graft rod, the balloon assembly is used to open the intervertebral space and build a fenced absorbable cement structure, and the bone cement input device is used to Absorbable bone cement is injected, the bone graft assembly is used for pressurized bone graft, and the corresponding fusion method is disclosed. The invention adopts double balloon folding technology, the balloon volume is small, and the height of the intervertebral space can be stretched by the balloon pressure. Adjust the amount of bone graft according to clinical needs, change the current situation of uneven screw-rod reduction surgery, and improve the safety and efficiency of surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an endoscopic fusion device using absorbable materials to fence. Background technique [0002] In the past 30 years, with the improvement of the design of spinal internal fixation equipment and the improvement of surgical techniques, lumbar fusion technology has achieved rapid development in the medical field. Although various fusion methods can obtain ideal clinical curative effect, it has been found in clinical practice that the increase in fusion rate after lumbar fusion does not necessarily accompany the corresponding improvement in clinical curative effect. Faced with various new fusion technologies, how to make The correct choice has become a difficult problem for spine surgeons. [0003] Several considerations need to be considered for fusion and internal fixation technology at this stage: 1. The size of the trauma; 2. The material of the fusion device used to res...
