Abstract

The invention discloses a boosting device for filling bone cement during percutaneous vertebroplasty. The boosting device is used for filling the bone cement during the percutaneous vertebroplasty and comprises a bone cement injection sleeve, a bone cement injection push rod, a push rod handle and a sleeve handle, wherein the push rod handle is fixed on the bone cement injection push rod, the sleeve handle is fixed on the bone cement injection sleeve, the bone cement injection push rod can be placed in the bone cement injection sleeve and can move back and forth, and the top end of the sleeve handle and the bottom of the push rod handle are provided with mutually coupled threads and the sleeve handle and the push rod handle can be fixed together through the threads. By using the boosting device to fill the bone cement during the percutaneous vertebroplasty, the advantages of convenience in operation, practicability and simplicity are achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a booster device for filling bone cement in percutaneous vertebroplasty. Background technique [0002] Vertebral fractures can lead to dysfunctional pain that lasts for several months. This pain can cause the patient to lose labor and exercise capacity, and can quickly cause loss of limb function, atelectasis and pneumonia, deep vein thrombosis and pulmonary embolism, etc. A fatal complication, vertebral body compression fractures were also the cause of many elderly people's inability to take care of themselves and loss of independent living in the past. The use of a large amount of drug treatment often causes drug side effects and drug dependence, and most patients do not accept or cannot tolerate surgical treatment. At present, percutaneous vertebroplasty is used to treat vertebral body compression fractures. It is guided by a C-arm machine to puncture the fractured vertebral body through t...
