Description
Technical field
The present invention relates to a kind of 3D and print percutaneous puncture Thoracolumbar disk and surrounding tissue internal organs omniselector and air navigation aid thereof, belong to Medical Image Processing and application.
Background technology
Spinal column associated pain is the disease that causes due to various spinal column reasons of a class or syndrome.The common cause of disease has: intervertebral disc prolapse, compression fracture of vertabral body, sympathetic diseases related, back Pain-syndrome, discogenic pain, spinal stenosis, malignant disease etc..Raising and the quickening of disease rejuvenation trend along with aged tendency of population degree, spinal column associated pain, especially Thoracolumbar disk disc herniation, discogenic pain, osteoporotic vertebral fracture, malignant disease (such as malignant metastatic tumor of bone) etc. have become as threat national healthy and the commonly encountered diseases of quality of life, frequently-occurring disease.
The less invasive techniques for the treatment of spinal column associated pain has at present: the micro-wound pressure-reduced art of intervertebral disc (radio frequency, laser, plasma, ozone etc.) and enucleation (percutaneous foramen intervertebrale lens etc.), vertebroplasty, sympatholytic and radiofrequency ablation, lumbar spinal nerve block and radiofrequency ablation, Intraperitoneal chemohyperthermia and radiofrequency ablation etc..Puncture the key being precisely to ensure therapeutic effect, tradition minimally-invasive treatment, according to body surface anatomical structure, relies on individual's clinical experience to puncture, utilizes the auxiliary such as C arm, CT to guide, improve treatment accuracy, but complex operation step, positioning accurate parasexuality is poor, the longest, doctors and patients radiate greatly, to carrying out the patient of multiple location treatment, operating increasingly difficult, 3D printing technique makes personalized precisely puncture be possibly realized.
At present, Chinese patent literature CN104958099A discloses a kind of 3D and prints foramen intervertebrale lens targeting puncture percutaneous surgical guide, Chinese patent literature CN105193492A discloses the percutaneous cervical arc root guide plate that a kind of 3D prints, below it is all to utilize 3D technology to print a guide plate, on have the puncture post for puncturing, this guide plate is positioned at back by medical sheet of pasting.With upper guide plate only for single vertebral body and single intervertebral disc puncture site, for need to carry out the operation of multiple sites puncture at lumbar vertebra or thoracic vertebra and surrounding tissue internal organs, not only need to print multiple guide plate, time-consuming take material, increase treatment cost, and due to human waist and back skin slightly radian, arranging large stretch of guide plate pedestal that punctures at lower back can affect the trickle adjustment in puncture needle direction, and then affects puncture success rate.
The most often need to carry out multi-segmental (such as multiple compression fracture of vertabral body, multi-segmental intervertebral disk hernia etc.), multi-method (simultaneously combining the radio-frequency (RF) therapy etc. of vertebral body Tumors tissue as vertebral body metastatic tumo(u)r carries out vertebral body plastic operation), multipath (such as the bipolar radio frequency etc. of intervertebral disc prolapse) minimally-invasive treatment, the guider of the present invention can realize the accurate puncture in many sites, is greatly shortened operating time, reduces doctor and patient radiation while ensureing therapeutic effect, reducing complication.In addition, the guider of the present invention can be applied not only to spinal column associated pain, can be also used for the accurate puncture of thoracic vertebra, lumbar vertebra surrounding soft tissue and internal organs, as kidney and lungs puncture, the site of puncture that all iconographys can reach all can use the guider of the present invention to realize efficient precisely puncture.
Compared with above two invention, the guider design of the present invention is succinct, slideway area of base is little, it is more easy to fit with lower back, it also avoid bulk simultaneously and be attached at the puncture drawback that the visual field is narrow and small, be difficult to puncture needle finely tunes that the guide plate pedestal of lower back is brought, in addition, succinct design makes the guider compact of the present invention, print required consumptive material few, printing required time is short, substantially reduce the realization of the design-printing-Clinical practice one-stop service in path design-3D cycle time-write interval, beneficially guider.
