Description
Technical field
A kind of medical apparatus and instruments applied during the operation of a kind of medical apparatus and instruments, particularly pedicle applied when this utility model belongs to vertebral body operation, is particularly related to percutaneous cervical arc root guide plate that a kind of 3D prints and preparation method thereof.
Background technology
Relate to the Minimally Invasive Surgery operation of pedicle, comprise percutaneous vertbroplasty or balloon kyphoplasty or percutaneous cervical arc root fixation etc., current pedicle maximum difficult point of performing the operation accurately determines the entry point of pedicle and enters to follow closely direction.The modus operandi adopted has traditional cutting operation and the percutaneous surgery of Wicresoft.Traditional cutting operation determining that pedicle of vertebral arch has the guide plate related in this when entering to follow closely direction, owing to recognizing for the anatomic landmark of concrete vertebral body in art, so easily find the use location of guide plate.And Minimally Invasive Surgery is the operation of percutaneous, by vertebra skin of back, only can substantially determine vertebral body position, therefore be difficult to recognize definite operation vertebral body position by vertebral body dorsal skin merely, now in order to determine that more operation vertebral body needs to carry out x-ray bombardment and determine, determine pedicle enter to follow closely direction time also need to be determined by a large amount of X-ray scannings more.Therefore need a kind of pedicle of vertebral arch guide plate of applicable percutaneous cervical arc root operation easy to use, and can individuation be realized.
Along with the development of digitized and 3D printing technique, personalized treatment is realized at medical domain, the therapeutic device of preparation personalization becomes possibility, according to the scan-data of patient itself, carry out digital assay, carry out matching, forming personalized data, utilize 3D printing technique by the prosthese of design or apparatus printing shaping.
Less about the pedicle of vertebral arch guiding technique patent of percutaneous at present, although there is the pedicle of vertebral arch guide plate of percutaneous, 3D prints percutaneous cervical arc root guide plate 201420318412.5, but this guide plate only comprises one piece of guide plate and pedicle sleeve, determine any block vertebral body carry out performing the operation and guide plate placement location time still need X-ray to scan, the accurate placement to guide plate could be realized.Dependence to X-ray scanning in art when prior art guide plate still can not avoid percutaneous cervical arc root to perform the operation, the application of guide plate is comparatively complicated.
For the patent solving existing percutaneous cervical arc root guide plate is less and can not break away from the dependence of X-ray scanning in use procedure and use the problems such as convenient not, percutaneous cervical arc root guide plate that this utility model provides a kind of 3D to print and preparation method thereof.
Utility model content
Can not break away from the dependence of X-ray scanning in guide plate use procedure to overcome prior art and use the problems such as convenient not, the purpose of this utility model is to provide percutaneous cervical arc root guide plate that a kind of 3D that can solve the problem prints and preparation method thereof.
