Abstract
The utility model relates to an expansion assembly of vertebroplasty system for minimally invasive treatment for vertebral compression fracture, which comprises an expansion guiding tube and an expansion sleeve. The external diameter of the expansion guiding tube matches with the inner diameter of the expansion sleeve, an expansion guiding tube handle is arranged at the upper end of the expansion guiding tube and an expansion sleeve handle is positioned at the upper end of the expansion sleeve. The expansion guiding tube handle is in threaded connection with the expansion sleeve handle. By means of threaded connection, matching between a positioning block and a positioning groove and matching between a fastener and a fastener groove, perfect and reliable connection between the expansion guiding tube and the expansion sleeve is achieved. In addition, the expansion assembly of vertebroplasty system for minimally invasive treatment for vertebral compression fracture can be detached and mounted conveniently, and is reasonable in design and high in practicability.
Description
Technical field
This utility model relates to a kind of medical surgical instrument, particularly a kind of minimally-invasive treatment compression fracture of vertabral body vertebral plasty system Stent assembly.
Background technology
Along with the population senescence, osteoporosis becomes a kind of commonly encountered diseases of harm middle-aged and elderly people health.The total prevalence rate of China's mid-aged population osteoporosis is 12.4%, and prevalence increases with the age, and the sickness rate of osteoporotic compression fracture of vertabral body is 10% more than 60 years old.Vertebral compression fracture also can be caused by tumor invading, application class steroid hormone etc.Traditional treatment is an expectant treatment, comprise lie up, analgesic, physical therapy, support etc.But bed has more been quickened losing with muscle committee of bone and has been contracted, and pain increases the weight of thereupon.The osteoporosis centrum internal fixation is unreliable, and osteotomy orthopaedy is not greatly generally considered very much because of its wound behind the vertebral body kyphosis deformity vertebra.
