Percutaneous vertebroplasty (PVP) operating system capable of bilaterally injecting bone cement at same time

Abstract

The invention provides a percutaneous vertebroplasty (PVP) operating system capable of bilaterally injecting bone cement at the same time. The system comprises a puncture needle 1, a puncture needle 2, a connection pipe 3, a connection pipe 4, a three-way device 5 and a conveyor 6, the puncture needle 1 is connected with the connection pipe 3, the puncture needle 2 is connected with the connection pipe 4, the other end of the connection pipe 3 and the other end of the connection pipe 4 are connected with two ends of the three-way device 5, and the conveyor 6 is connected with the other end of the three-way device 5, wherein the three-way device 5 is provided with a switch 7.

Description

[0001] Technical field: [0002] The invention relates to a medical device, in particular to a vertebroplasty (PVP) operating system for bilateral bone cement injection for minimally invasive treatment of patients with osteoporotic compression fractures. [0003] Background technique: [0004] The clinical full name of vertebroplasty is percutaneous vertebroplasty (percutaneous vertebro plasty, PVP), which is a minimally invasive technique for the spine. Vertebral technology. It was invented and first applied by Deramond in 1984. In 1987, French physician Galibert first applied it to the treatment of vertebral hemangioma. In 1994, the United States first reported the application of PVP to the treatment of osteoporotic vertebral fractures. [0005] The pain relief mechanism of PVP may be the anchoring of bone cement in the fractured vertebral body, which fixes the micro-fractures in the osteoporotic vertebral body, increases the stability of the vertebral body, and thus reduces...

AI Technical Summary

Problems solved by technology

[0007] Traditional PVP surgery also has obvious deficiencies. First of all, the radiation exposure of doctors and patients is quite large, because repeated fluoroscopy is required to locate the puncture needle during the operation, and it is also necessary to repeatedly fluoroscopy the patient's vertebral body when injecting bone cement to determine the position and quantity of bone cement. Prevent leakage, so both doctors and patients have been exposed to a lot of X-rays; secondly, the working time of bone cement is limited, only 3-5 minutes, due to the cumbersome operation steps of PVP, it is easy to miss the best working time of bone cement

If the bone cement injection time is too late, it will harden and make it difficult to inject into the vertebral body, resulting in failure of the operation; if it is injected too early, it is not injected during the toothpaste period or the injection speed is too fast, there is a great risk that the bone cement will leak around the fractured vertebral body , causing serious adverse consequences
