Embodiment 1

[0023] as attached figure 1 As shown, the vertebral body expansion device is composed of a balloon 1, a delivery tube 3, a glue injection tube 2, and a purple light lamp 4. The balloon 1 has an opening with threads, and one end of the delivery tube 3 is also threaded, the balloon 1 and the delivery tube 3 are connected by threads, the delivery tube 3 is a hollow structure, and the glue injection tube 2 passes through the delivery tube 3 Entering the inside of the balloon, the purple light lamp 4 is installed on the side surface of the glue outlet end of the glue injection tube 2 . The balloon is made of PCL degradable material with a molecular weight of 50,000.

[0024] When in use, the balloon is sent to the affected area through the delivery tube, and the glue injection tube 2 enters the inside of the balloon 1 through the channel inside the delivery tube 3. While the silk fibroin is being injected, the purple light is turned on. Exit the glue injection tube 2 and delivery...

Abstract

The invention relates to a centrum dilatation device and a use method. The centrum dilatation device provided by the invention is used for solving the problems of the existing centrum fracture treatment scheme that secondary fracture is easily caused due to the fact that bone cement is relied and the stress is large after bone cement shaping and other serious complications are caused by leakage ofthe bone cement; and a ball bag is degradable. The centrum dilatation device provided by the invention comprises the ball bag, a conveying pipe and a glue injection pipe, wherein one end of the ballbag is provided with a threaded opening, one end of the conveying pipe is accompanied with threads and is in detachable threaded connection with the ball bag, the conveying pipe is of a hollow structure, and the glue injection pipe can penetrate through the interior of the conveying pipe and enter the interior of the ball bag.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cone expansion device and a use method. Background technique [0002] With the aging of the population and people's emphasis on the quality of life, osteoporosis has gradually become a social problem that plagues the elderly. More and more attention has been paid to the medical and social problems brought about by senile osteoporosis and the fractures it causes. Osteoporotic fractures are serious consequences of osteoporosis. Due to decreased bone mass, decreased bone strength, and increased bone fragility, brittle fractures can be caused by minor injuries in daily activities. Most of these fractures are complete fractures, while bone Osteoarthritis vertebral compression fracture (OVCF) is the most common fracture. The healing process of this type of fracture is slow, the patient population is older, the surgical treatment is difficult and risky, and the clinical efficacy i...
