Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to three dimensional CT in a kind of art based on mobile convolution C-arm
Equipment.
Background technology
With the development of minimally invasive surgery, pedicle screw Internal fixation technology progressively turns into the routine of Thoracolumbar disk surgical operation
Operate, after thoracolumbar bursting fractures, the bone piece of fragmentation can be moved to the position of canalis spinalis, so as to spinal cord, circular cone or cauda equina nerve
Produce physical pressure.This disease may allow patient to lose, and part is felt or therefore motor function, backbone may also can be
Loss of stability.It is CT scan clinically to make a definite diagnosis the maximally effective auxiliary examination methods of this disease.AO parting A3 type Thoracolumbar disks are quick-fried
It is that sclerite bursts to surrounding to split Bone fracture characteristics, and compressing may be caused to produce nervous symptoms to dural sac, nerve root.And grind
Study carefully and show that A3 types fracture has humpback risk.Operative treatment is that the effective way of backbone, Ke Yijin are oppressed and stablized in solution
Hang Qian roads and posterior approach.Some patients receive the treatment of posterior Pedicle screw distraction reduction internal fixation operation, do not go
Laminectomy depressurizes.Between past 20 years, the application of pedicle screws fixation clinically is increasingly extensive, and posterior approach becomes
Must be more ripe, reach the reduction of the fracture, the purpose that vertebral canal volume recovers.But have scholar's discovery, small number of patients it is postoperative
CT scan shows the obvious bone piece that residual on canalis spinalis position still be present, and canalis spinalis caliber is not because operative treatment reaches just again
Often or close to normal level, pedicle screw position is also bad, iatrogenic nervous function damage occurs, causes doctors and patients double
Square relation becomes more nervous, therefore patient will receive further to treat.
Causing having its source in for this phenomenon, the key link in operation --- pedicle of vertebral arch implant surgery operates, Ji Jianggu
Surely centrum of the pedicle screw through pedicle of vertebral arch implantation backbone.Traditional pedicle of vertebral arch implant surgery operation is that doctor relies on
The specialized skills of oneself, the X light image that the C-arm according to operating room is shot, adjust operation pathway, complete pedicle of vertebral arch implantation hand
Art operates, and in the case of not opening patient's canalis spinalis in art, lacks the skill for being resetted to centrum rear wall and carrying out effective evaluation
Art, existing achievement in research do not provide the method for being capable of accurate evaluation canalis spinalis recovery situation.
In general C-arm x-ray equipment mainly includes apparatus body, C-arm, ray source and Imaging Plate；C-arm is slided
Dynamic to be arranged at apparatus body, so that C-arm can circumferentially be slid with relative device body, ray source is relative with Imaging Plate to be set
Put, be respectively arranged at the both ends of C-arm opening.This equipment typically only has perspective function, it will be appreciated that whether sclerite returns
Normal position, it usually needs centrum trailing edge " straight line " or " preceding camber line " are observed, so as to understand Spinal canal encroachment situation, with
The correlations such as the practical experience of operator, perspective technician are horizontal, C-arm perspective readability in itself, Perspective Conditions.Also
Have at present that mobile C-arm CT scanning range is smaller, three-dimensional reconstruction dynamic interference is big, and blind area is more, can not meet in operation precisely
The needs of assessment, different plus the professional standards of doctor, this may result in many operations and different degrees of sequelae occurs.
The content of the invention
For above technical problem, the present invention provides three-dimensional CT equipment in a kind of art based on mobile convolution C-arm, energy
Enough effectively solve that conventional c-arm CT equipment visual angle is single, scan blind spot is more, and can not in art flexible Application technical problem.
