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 l

[0030] Including the following components, puncture needle 1 and puncture needle 2, connecting tube 3 and connecting tube 4, three-way device 5, conveyor 6, wherein, puncture needle 1 and connecting tube 3 are connected, and puncture needle 2 and connecting tube 4 are connected , the other end of the connecting pipe 3 and the connecting pipe 4 are connected to the two ends of the three-way device 5, and the conveyor 6 is connected to the other end of the three-way device 5, wherein the three-way device 5 is equipped with a switch 7, which can control the three-way The connection or disconnection of any channel of the device 5.

Embodiment 2

[0032] Method of use of the device of the present invention

[0033] Under X-ray fluoroscopy, the fractured vertebral body was confirmed, and the puncture needle 1 on one side was first inserted through the pedicle channel. figure 1 ), and then insert another puncture needle 2 through the pedicle channel on the other side.

[0034] The puncture needles 1 and 2 are hollow, and the ends of the body are connected with the connecting pipes 3 and 4 by nuts.

[0035] Two connecting pipes3,4( figure 2 ) is connected with the two outlets of the tee device 5 joint

[0036] Mix the bone cement powder and water, mix well, put the bone cement into the mixer, and empty the air.

[0037] The stirred bone cement is transported to the three-way device 5 through the conveyor 6, and the working channel is established at this time, and the bone cement is ready to be injected into the fractured vertebral body

[0038] Open the two valves 7 of the three-way interface to keep the unobstructed ...

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...
