Description
Technical field
This utility model belongs to medical apparatus field, is specifically related to a kind of vertebra posting facilitating Thoracolumbar disk operation consent to locate.
Background technology
Thoracolumbar disk operation is a large class operation common in orthopaedics vertebra, and the advantage of minimally invasive spine surgical is that otch is little, and preoperative body surface location is very important for minimally invasive spine surgical accurately, if locate inaccurate, otch just certainly will be caused to extend, thus increases damage.Vertebra localization method the most frequently used is clinically Kirschner wire positioning mode at present.But Kirschner wire positioning mode because of perspective view limited, can only 2 ~ 3 vertebral bodys, and respectively centered by sick vertebra row transverse section, coronalplane and sagittal plane repeatedly irradiate location, need repeatedly move C-arm X-ray machine and Kirschner wire, Fluoroscopy location can determine pedicle of vertebral arch repeatedly, this not only extends operating time, and adds the radiation injury that patient and medical worker be subject to.
Other conventional spinal localization methods have a lot: (1) anterior superior iliac spine positioning mode; (2) rib positioning mode; (3) vertebra form positioning mode is hindered; (4) skin marker thing positioning mode etc.These methods mainly rely on bone mark to locate vertebral body, often by the impact of many factors, as divide a word with a hyphen at the end of a line variation, the position of patient, the experience etc. of patient of vertebral body can cause vertebra localization mistake in art.
Cai Junfeng etc. devise spinal column positioning rule and are applied in the prelocalization of thoracic and lumbar vertebral posterior surgery; Tan Qing reality etc. devises lumbar vertebra locator application in the preoperative location of Microendoscopic; Xu Haiyun etc. devise the application of pedicle of vertebral arch network for location pedicle of vertebral arch location in balloon angioplasty balloon kyphoplasty art; He Shisheng etc. devise Wicresoft's locator application in the preoperative location of minimal invasive lumbar surgery.These different apparatuses meet the feature of related surgical mode, have certain advantage, but simultaneously also there are some defects, as: orientation tool structure is too complicated, scale marker design is unreasonable, length and width do not meet Thoracolumbar disk anatomical features etc.
Summary of the invention
The purpose of this utility model is for existing Thoracolumbar disk location of operation complex steps, patient and medical worker are subject to the larger deficiency of the radiation of C arm machine, a kind of vertebra posting is provided, its structure is simple, adopt vertebra posting to position before Thoracolumbar disk surgery, location is convenient, and C arm machine is carried out once irradiating and just can accurately be located, shorten operating time, decrease the radiation injury that patient and medical worker are subject to.
In order to solve the problems of the technologies described above, this utility model by the following technical solutions:
This utility model comprise framework, horizontal divider, longitudinal subdivision bar, to line raised line, indicia patterns frame, connecting rod, gear and rotating shaft; Described framework is rectangular, and four horizontal dividers are all fixed with framework, and framework is longitudinally divided into five mark zones; Described longitudinal subdivision bar is fixed on the longitudinal centering line place of framework; In each mark zone, longitudinal frame of framework both sides is fixed with two of symmetry to line raised line; Described is arranged line raised line is vertical with longitudinal frame of framework, and aligns with the horizontal center line of mark zone to the centrage of line raised line; Symmetrically arranged two line raised line is fixed by connecting rod; Longitudinal subdivision bar is positioned at five mark zones and is respectively fixed with a different indicia patterns frame; Longitudinal frame of framework all offer in each mark zone with to the chute of tackling line raised line and form sliding pair, described chute is arranged along the longitudinal direction of framework; Every root forms gear pair to the teeth at line raised line top and a gear; Described gear is hinged in framework by rotating shaft, and the part gear teeth expose outside framework.
Described framework, horizontal divider, longitudinal subdivision bar, titanium alloy is to the material of line raised line, indicia patterns frame, connecting rod, gear and rotating shaft.
The longitudinal length of described mark zone is 30mm, is 10mm to the longitudinal length of line raised line.
Indicia patterns frame is from top to bottom respectively circular frame, rectangle frame, equilateral triangle frame, diamond and square-shaped frame.
The diameter of described circular frame, the longitudinal length of rectangle frame, the height of equilateral triangle frame, the diagonal line length of diamond are equal with the length of side of square-shaped frame, are equal to the longitudinal length to line raised line.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model structure is simple, and location is convenient, and C arm machine is carried out once irradiating and just can accurately be located, and has shortened operating time, decreases the radiation injury that patient and medical worker are subject to.
2, framework is longitudinally divided into five mark zones by this utility model, the longitudinal length of each mark zone is close to the length of vertebral segments, ensure that C arm machine irradiates maximum magnitude labelling vertebral segments quantity under definition, so as convenient, aim at lesion locations fast.
3, indicia patterns frame of the present utility model can know the mark zone identifying correspondence, avoids judging mark zone by accident, causes malpractice.
4, of the present utility modelly can be finely tuned by transmitting gear line raised line, to make the location of lesion locations in each mark zone more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
As illustrated in fig. 1 and 2, a kind of vertebra posting, comprise framework 1, horizontal divider 2, longitudinal subdivision bar 3, to line raised line 4, circular frame 5, rectangle frame 6, equilateral triangle frame 7, diamond 8, square-shaped frame 9, connecting rod 10, gear 11 and rotating shaft 12; Framework 1 is rectangular, and four horizontal dividers 2 are all fixed with framework 1, and framework 1 is longitudinally divided into five mark zones; Longitudinal subdivision bar 3 is fixed on the longitudinal centering line place of framework 1; In each mark zone, longitudinal frame of framework both sides is fixed with two of symmetry to line raised line 4; Arrange line raised line 4 is vertical with longitudinal frame of framework, and the centrage of line raised line 4 is alignd with the horizontal center line of mark zone; Symmetrically arranged two line raised line 4 is fixed by connecting rod 10; Longitudinal subdivision bar 3 is positioned at each mark zone and is fixed with circular frame 5, rectangle frame 6, equilateral triangle frame 7, diamond 8 and square-shaped frame 9 from top to bottom respectively.Framework 1, horizontal divider 2, longitudinal subdivision bar 3, titanium alloy is to the material of line raised line 4, circular frame 5, rectangle frame 6, equilateral triangle frame 7, diamond 8 and square-shaped frame 9.
The value of the longitudinal length a of mark zone is 30mm, and to the longitudinal length b=10mm of line raised line 4, the length of side of the diameter of circular frame 5, the longitudinal length of rectangle frame 6, the height of equilateral triangle frame 7, the diagonal line length of diamond 8 and square-shaped frame 9 is L=10mm.
