Description
Technical field
The invention belongs to the bone surgery spinal surgery technical field of medical instruments of clinical medicine, be specifically related to a kind of breast pedicle of lumbar vertebra Fluoroscopy location dish for the prelocalization of breast lumbar surgery.
Background technology
Before thoracic vertebra or lumbar surgery, usually need clinically to carry out X-ray examination with accurate positioning operation sections and pedicle locations, traditional orientation tool as many pieces of Kirschner wires etc. need to be with immobilization with adhesive tape in skin, there is pair skin to cause the risk of stimulation, after perspective imaging, identification other to left and right sides and upper and lower relation is also more difficult, and need to adjust Kirschner wire position, consuming time longer.
Summary of the invention
Goal of the invention: the invention provides a kind of breast pedicle of lumbar vertebra Fluoroscopy location dish for the preoperative location of breast lumbar vertebra, its object be to facilitate adjust identification point position, be beneficial to and distinguish left and right sides not and upper and lower relation, minimizing perspective number of times, and accurately positioning operation sections and pedicle locations.
Technical scheme: the present invention implements by the following technical programs:
A kind of breast pedicle of lumbar vertebra Fluoroscopy location dish for the preoperative location of breast lumbar vertebra, it is characterized in that: this positioning disk by positioning disk framework, sliding bar, in minute vertical pole and positioning mark form, positioning disk framework is rectangle stable frame, article two, stringer frame transverse section is provided with groove, opening part is slightly narrow, positioning disk framework is macromolecular material, can see through X ray; The two ends of sliding bar are for expanding part, are contained in the groove of positioning disk framework and can move up and down and can not skid off; Two frames up and down of positioning disk framework are solid, with in a minute vertical pole be fixedly linked; Different some positioning marks are arranged on sliding bar, can move left and right.
The central authorities of sliding bar are provided with a metal wire, and during X-ray examination, metal wire can develop, more accurately to judge position location; Sliding bar outer wrapping macromolecular material, is convenient to control with the frictional force of positioning mark slidably and has no abnormal sound when the latter slides; Expand at sliding bar two ends, is positioned at positioning disk framework 1 stringer frame, and the two coupling is good, and what push away can slide up and down and do not deviate from; Sliding bar can suitably be adjusted according to the distance of upper hypocentrum pedicle of vertebral arch, accurately to locate pedicle of vertebral arch sections and position.
In the central authorities of minute vertical pole be provided with a metal wire, during X-ray examination, metal wire can develop, overlapping with position and the spinous process line of in guaranteeing minute vertical pole, wire diameter is little simultaneously, does not affect and observes and the position relationship of spinous process; Outer wrapping macromolecular material, does not develop, and does not affect perspective.
The section of sliding bar is oval or square, crosses positioning mark, and guarantees that positioning mark does not rotate.
Positioning mark is metal material, can not see through X ray.Positioning mark is different, to distinguish different pedicle of vertebral arch subpoints, and by the polygon of positioning mark itself, can locate the position of pedicle of vertebral arch projection, simultaneously in conjunction with sliding bar and in the relative position relation of minute image that vertical pole becomes, be more conducive to accurate location, and reduce perspective number of times.
Advantage and effect:
1, breast pedicle of lumbar vertebra Fluoroscopy location dish is integrated frame structure, directly places Rhizoma Atractylodis Macrocephalae district, easy to use;
2, each functional part is adjustable, is suitable for different build patients;
3, each Fluoroscopy location sign shape is different, be not convenient to recognize left and right sides not and upper and lower relation, by the polygon of positioning mark itself, can locate the position of pedicle of vertebral arch projection, simultaneously in conjunction with sliding bar and in the relative position relation of minute image that vertical pole becomes, be more conducive to accurate location, and reduce perspective number of times.
4, minute vertical pole projection mark in cut line edge, avoids otch deflection.

In figure, mark: 1. positioning disk framework, the anti-skidding edge of 1a. framework stringer frame groove, 1b. framework stringer frame groove, 2. sliding bar, 2a. sliding bar two ends expand portion, 2b. sliding bar pars intermedia, 3. in minute vertical pole, 4. positioning mark slidably.
the specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in the figure, positioning disk framework 1 is rectangle stable frame, and two stringer frame transverse section are " recessed " type groove 1b, and opening part is slightly narrow, anti-skidding edge 1a, consists of, and sliding bar 2 two ends are expanded part 2a and held wherein and not and can skid off; Upper and lower two frames are solid, with in a minute vertical pole 3 be closely connected; Positioning disk framework 1 is macromolecular material, can see through X ray.
Sliding bar 2 mid portion 2b sections are oval or square, cross slidably positioning mark 4, and guarantee that the latter does not rotate; Sliding bar 2 mid portion 2b central authorities are a metal wire, and during X-ray examination, metal wire can develop, more accurately to judge position location; Sliding bar 2 outer wrapping macromolecular materials, are convenient to control with the frictional force of positioning mark 4 slidably and have no abnormal sound when the latter slides; Expand at sliding bar 2 two ends, is positioned at positioning disk framework 1 stringer frame, and the two coupling is good, and what push away can slide up and down and do not deviate from; Sliding bar 2 can suitably be adjusted according to the distance of upper hypocentrum pedicle of vertebral arch, accurately to locate pedicle of vertebral arch sections and position.
In minute vertical pole 3 central authorities be a metal wire, during X-ray examination, metal wire can develop, overlapping with position and the spinous process line of in guaranteeing minute vertical pole, wire diameter is little simultaneously, does not affect and observes and the position relationship of spinous process; Outer wrapping macromolecular material, does not develop, and does not affect perspective.
Slidably positioning mark 4 is metal material, can not see through X ray; Positioning mark 4 shapes are different, be convenient to accurate positioning operation sections, pedicle locations and distinguish upper and lower relation, conventionally only by the polygon of positioning mark itself, can locate the position of pedicle of vertebral arch projection, simultaneously in conjunction with sliding bar and in the relative position relation of minute image that vertical pole becomes, be more conducive to accurate location, and reduce perspective number of times; Positioning mark 4 can move left and right on sliding bar 2 mid portion 2b, to be applicable to the difference of different patients both sides interpedicular distance.
The present invention is for the prelocalization of breast lumbar surgery, both can conveniently adjust identification point position, be beneficial to and distinguish left and right sides not and upper and lower relation, minimizing perspective number of times, accurately positioning operation sections and pedicle locations again.
After general anesthesia success, patient gets ventricumbent position (local anaesthesia patient directly gets ventricumbent position), and breast pedicle of lumbar vertebra Fluoroscopy location dish is placed in to lower back, roughly covers surgical target region, and in maintenance, minute vertical pole is consistent with spinous process line.Mobile C arm machine, perspective, adjusts positioning disk position if desired.Subpoint according to the corresponding relation labelling operation sections of Fluoroscopy location home position and pedicle of vertebral arch and pedicle of vertebral arch at body surface, labelling cut line.Routine disinfection, paving aseptic operation list, carries out next step operation technique.
