Description
This utility model relates to a kind of operating assistive device that is used for, and exactly is to be used for the lumbar intervertebral disc localized medical apparatus and instruments that punctures.
At present, adopt puncture to cut for prolapse of lumbar intervertebral disc more and inhale treatment, compare with operation have painful little, go out insufficiency of blood, injury of the bone bone not, rehabilitation is fast, to advantages such as spinal stability have no effect, but the most important ring of puncture for treating is exactly to determine that puncture needle enters the optimum position and the puncture needle location of intervertebral space, mostly being free-standing exercise now in the hospital greatly does, during puncture, under the X-ray irradiation, carry out, have certain blindness, the puncture accuracy is relatively poor, be difficult to one-time puncture to the optimum position, often want repetitive operation for several times, also just be tending towards the optimum position, bring unnecessary misery to patient, make medical worker and patient be subjected to the irradiation of too much X ray simultaneously.
The purpose of this utility model is to provide a kind of adjustable lumbar vertebra intercalated disc puncture locator, makes that the puncture of blindness becomes the puncture that shoots the arrow at the target at present, guarantees that one-time puncture is to the optimum position.
The purpose of this utility model is achieved through the following technical solutions:
It comprises base 1, column 2 and platform 3 constitute, on platform 3, have chute 4, platform 3 surperficial along continuous straight runs are provided with a graduated scale 5, platform 3 is provided with slide plate 6, slide plate 6 intermediary slide rails 7 bottoms embed in the chute 4, slide plate 6 can slide on platform 3 surfaces along chute 4, fix one on the slide plate 6 and have graduated guide rail 8, guide pad 9 is set on the slide plate 6, guide pad 9 upper inclined surface have gathering sill 10, guide pad 9 fronts have one with the chute 11 of guide rail 8 matched in clearance, guide pad 9 slides along guide rail 8, guide pad 9 another sides are provided with adjusting knob 12, regulate arbitrarily by adjusting knob 12, fixed guide piece 9 height.
For when puncture the optimum position grasp more accurate, between platform 3 surperficial ends and chute 4, orthogonal bonding jumper 13a and 13b are set, bonding jumper 13a can horizontally slip along platform 3 surfaces, bonding jumper 13b and gathering sill 10 floor projections are at same straight line.
The percutaneous puncture lumbar intervertebral disc is cut and is inhaled the treatment prolapse of lumbar intervertebral disc, key is the location of puncture needle, through facts have proved, place, 1/3 center was the optimum position after puncture needle thrust intervertebral space, when adopting the operation of this puncture locator, patient is prostrate in this device below, under the X-ray irradiation bonding jumper 13a is aimed at patient's spinal column, and bonding jumper 13b aims at patient's intervertebral space centrage; Calculating site of puncture skin to the vertical dimension of optimum position by the CT sheet (is made as a), measure the horizontal range (be made as b) of site of puncture skin by the X-ray sheet to optimum position, moving metal bar 13a or slide plate 6 adjust point of puncture to bonding jumper 13a distance and are b, determine that then apart from point of puncture be position on the b place guide pad, the height of this position is transferred to a, puncture needle is put in the gathering sill 10, thrust in the patient body along gathering sill 10, utilize the congruent triangles principle, under the X-ray irradiation, can disposable exactly needle point be punctured to the intervertebral space optimum position.
Owing to adopt technique scheme, make the doctor under the guide of position finder, puncture, ground disposable puncture success ensures correctness, compared with prior art, generation and the medical personnel and patient's operating time under X-ray shines of the psoas major hematoma that puncture time and puncture caused have been reduced, alleviate the unnecessary misery of patient, improve therapeutic effect.
