Bone cement push-injecting multi-section synchronous micro-controller applied to percutaneous vertebroplasty

Abstract

The invention provides a bone cement push-injecting multi-section synchronous micro-controller applied to percutaneous vertebroplasty. The micro-controller is designed into a one-inlet two-outlet shunting structure. The flow of two outlets can be adjusted through an adjusting screw, a scaleplate is installed beside the adjusting screw, scale marks are arranged on the scaleplate, the accurate position of the adjusting screw can be displayed, and the opening sizes of the two outlets and the flow of bone cement of the two outlets can be further calculated. If three push-injection points exist, one device can be connected to one outlet again. If four push-injecting points exist, devices can be connected to the two outlets respectively. If five or more push-injecting ports exist, sequential connection can be carried out with the similar method, and the flow of each outlet can be controlled by adjusting the adjusting screw on each device. By means of the device, multi-point simultaneous push-injecting can be achieved, the bone cement is push-injected at a time after being mixed at a time, and the setting time is easy to control. Only one push-injector is used for multiple points, and thecost is low. X-ray irradiation is carried out once, and the radiation quantity received by the patient is small.

Description

Technical field: [0001] The invention relates to a multi-segment synchronous microcontroller for bone cement injection applied in percutaneous vertebroplasty Background technique: [0002] With the advent of an aging society, the incidence of osteoporosis is increasing year by year, and the incidence of osteoporotic fracture (OPF) is also increasing. Common sites of OPF are the spine, hip, and distal forearm. Osteoporotic fractures in the spinal column, in particular, often occur with inadvertent small movements or injuries of the patient, resulting in severe pain and movement disorders, which have brought huge economic and living burdens to the society and the patient's family. In recent years, percutaneous bone cement perfusion vertebroplasty has been used to treat such injuries, and has achieved certain results, with the advantages of quick pain relief and good results. However, with the expansion of the number of clinical medical cases, it is also found that this type ...

However, with the expansion of the number of clinical medical cases, it is also found that this type of technology has certain defects

This type of equipment is used in a complete set, and a set of equipment can only be applied to one vertebral body, which is expensive

For patients with multiple segmental vertebral fractures, the economic burden is huge; moreover, bone cement injection at multiple segments or multiple puncture points cannot be performed at the same time during the surgical treatment, resulting in multiple X-ray fluoroscopy, and the patient received X-ray The amount of radiation radiation is too large; due to the limitation of the setting time of the bone cement, the operation time must be completed in the shortest possible time. If it is multi-segment or multi-point treatment, the bone cement may appear in the vertebral body due to the hardening of the bone cement. Poor diffusion, unable to push injection, unable to insert the puncture needle core, leading to complications such as tailing when the puncture needle is pulled out
