Description
Technical field:
This utility model relates to a kind of making animal pathological model utensil, is specifically related to build the modeling utensil of animal prolapse of lumbar intervertebral disc pathological model.
Background technology:
Prolapse of lumbar intervertebral disc is the clinical commonly encountered diseases of orthopaedics, frequently-occurring disease, has a strong impact on people's live and work, but because of its definite pathology diease occurrence mechanism still not fully aware of, so its clinical efficacy is very dissatisfied.Chinese scholars has been carried out more animal model experiment research to this disease, but its model respectively has weak point, as silica gel tube or silica gel sheet are inserted the urgent nerve root of intraspinal pressure to make lumbar nerve roots chronic mild compressing model, but exist silica gel to substitute disc tissue, former intervertebral disc is organized intact, and has shortcomings such as vertebral body and the heavy damage of intervertebral space rear structure.There is the scholar after the excision of way of escape row semi-vertebral plate, will be transplanted to outside the die from body homology nucleus pulposus, produce model of lumbar intervertebral disc protrusion, this class model can make the disc tissue of transplanting break away from former self interior environment and rear structure and be subjected to heavy damage, be to have a certain distance between model and the actual prolapse of lumbar intervertebral disc, be difficult to build exactly the prolapse of lumbar intervertebral disc pathological model.At present, the people who suffers from the prolapse of lumbar intervertebral disc shape is comparatively common, if can design a kind of new apparatus of building animal pathology model of lumbar intervertebral disc protrusion, make its modeling type more approach the pathological state of human prolapse of lumbar intervertebral disc, will be significant to this sick pathology diease occurrence mechanism and study on prevention.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of modeling utensil that can build animal prolapse of lumbar intervertebral disc pathological model exactly is provided.
Technical problem of the present utility model is to realize by following technical scheme.It is characterized in that it is to be formed by the mutual successively fit of puncture needle, puncture needle tubing and adjustable pipe, wherein between puncture needle and the puncture needle tubing, be slidingly matched mutually between puncture needle tubing and the adjustable pipe, the adjustment screw that can set puncture needle tubing and adjustable pipe relative position is housed on the adjustable pipe, and puncture needle tubing outer wall upper end is processed with master scale; Described puncture needle is provided with two, and the one syringe needle is a declivous cutting edge, and its two syringe needle is a flat edge.
This utility model can be built the prolapse of lumbar intervertebral disc pathological model exactly, has reduced the destruction of intervertebral disc adjacent bone structure and vertebra proximity of muscle, ligament and blood vessel; Make outstanding tissue from this intervertebral disc itself and maintenance and best the getting in touch of former intervertebral disc; Outstanding disc tissue is not away from environment in former; Interior environment around canalis spinalis and the nerve root is not damaged, and wound is little, and is simple, convenient, the puncture accurate positioning, and also the modeling utensil is cheap, is the comparatively ideal modeling utensil of present prolapse of lumbar intervertebral disc animal model.
Description of drawings:
Fig. 1 is this utility model structural representation;
Fig. 2 is this utility model plagiocephaly puncture needle sketch map;
Fig. 3 is this utility model tack puncture needle sketch map;
Fig. 4 is this utility model user mode figure.
Among the figure:
1-liner core print; 2-needle tubing head; 3-hands handle;
The 4-needle tubing that punctures; The 5-adjustment screw; The 6-adjustable pipe;
The 7-puncture needle; The 8-plush copper.
The specific embodiment:
As shown in Figure 1, this utility model comprises puncture needle 7, puncture needle tubing 4 and adjustable pipe 6, described puncture needle 7 is placed in the puncture needle tubing 4, be slidingly matched each other, liner core print 1 is equipped with in described puncture needle 7 upper ends, extract in easy to use and insert, this liner core print 1 upper end is a disk-like structure, its periphery evenly is processed with teeth groove vertically, slide in the time of can avoiding holds, liner core print 1 lower end is a pyramidal structure, and the big end of taper is provided with plush copper 8, small end is fixedlyed connected with puncture needle 7 one ends, forms an integral body; Described puncture needle tubing 4 one ends also are provided with needle tubing head 2, offer the bellmouth that can cooperate in these needle tubing head 2 its upper ends with liner core print 1, the top in its hole offers groove, liner core print 1 plush copper 8 can snap in this groove, can prevent puncture needle 7 slippages, and needle tubing head 2 stage casings are provided with handle 3, grasp when being convenient to operate, in order to puncture, fixedlying connected with puncture needle tubing 4 upper ends in its lower end, also forms an overall structure.This utility model also is processed with master scale in puncture needle tubing 4 outer walls upper end, and its outside is with adjustable pipe 6, also is slidingly matched mutually between the two, offers screw hole on adjustable pipe 6 sidewalls, and 1～2 adjustment screw 5 is housed on it.By the scale of puncture on the needle tubing 4 can set its with adjustable pipe 6 between distance, tighten the position that can fix puncture needle tubing 4 and adjustable pipe 6, the distance of also having fixed puncture needle 7 and adjustable pipe 6 simultaneously by adjustment screw 5 then.
This utility model puncture needle 7 is provided with two, and one is a declivous cutting edge syringe needle as shown in Figure 2, and cutting edge is sharp, and its length is for when liner core print 1 plush copper is stuck in needle tubing head 2 grooves, and puncture needle 7 oblique swords just are positioned at outside puncture needle tubing 4 mouths of pipe, and the inclined-plane height is about 1mm.Tiltedly cutlery has the function of cutting disc tissue, when rotation advances dissection is arranged, and is convenient to annular and cuts thorn and enter, and is complete in the time of can making the tissue of incision enter in the puncture needle tubing 4.When from the place ahead modeling, with this puncture needle 7, can avoid cutting off anterior longitudinal ligament when entering anterior longitudinal ligament with oblique sword, can withdraw from this puncture needle 7 through behind the anterior longitudinal ligament; It two is a flat edge syringe needle shown in Figure 3, when liner core print 1 plush copper is stuck in needle tubing head 2 grooves, and the just flat puncture needle tubing of puncture needle 74 mouths of pipe, its shank length is fashionable isometric with puncture needle tubing 4 covers.When using puncture needle 7 to release disc tissue, just release the disc tissue in it, and do not damage DEEP STRUCTURE.
Fig. 4 has showed the embodiment of an application of this utility model.As shown in the figure, the present embodiment total length is 102mm, and puncture needle 7 total lengths are 102mm, and puncture needle tubing 4 total lengths are 95mm, and external diameter is 1.6mm, and internal diameter is 1.0mm, and adjustable pipe 6 total lengths are 60mm.During concrete operations, plush copper 8 on the lining core print 1 within the puncture needle 7 of the oblique sword of present embodiment band is placed in puncture needle tubing 4 upper grooves, the oblique sword of puncture needle 7 front ends just stretches out puncture needle tubing 4 mouths of pipe, choose the degree of depth of inserting needle earlier according to the vertebral body anteroposterior diameter of animal, and by adjustable pipe 6 control, the degree of depth of directly reading puncture needle 7 inserting needles from the scale of upper end.After being punctured to the predetermined degree of depth, will be with the puncture needle 7 of oblique sword to extract out, tack puncture needle 7 is inserted in the puncture needle tubing 4, and shift disc tissue the place ahead of posterior longitudinal ligament onto, cause typical intervertebral disc prolapse model.
