Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of three-dimensional localization guider of percutaneous cervical arc root puncture.
Background technology
Because the superiority with spinal column three post fixed biologically terms of mechanics, way of escape pedicle nail technique for fixing is used widely in spinal surgery.Traditional modus operandi need extensively be peeled off paraspinal muscle, long-time retractor meat tissue, and operation wound is big, and is hemorrhage many, postoperative paraspinal muscle denervation, meat fiber scarring, shortcomings such as long-term low-back pain.Therefore, the percutaneous cervical arc root screw technology is more and more paid attention to, and develops rapidly.French scholar had started the percutaneous vertebroplasty in 1984, because it is used widely at spinal surgery having advantages such as wound is little, rapid-action, complication is few relatively aspect the diseases such as osteoporotic compression fracture, vertebral body metastatic tumo(u)r, vertebral body hemangioma.
Percutaneous cervical arc root screw technology and percutaneous vertebroplasty all need accurate in locating, percutaneous puncture pedicle of vertebral arch accurately.Human spine's anatomical features has determined accurate puncture pedicle of vertebral arch need determine three parameters: skin penetrating point, horizontal parallactic angle, sagittal parallactic angle.Spinal column breast lumbar vertebra form from top to bottom changes gradually, and the puncture parameter also changes gradually, also can change during Body Position Change, and the puncture parameter of hindering vertebra, sick vertebra also can change.Therefore, special tool(s) is auxiliary finishes the percutaneous cervical arc root screw technology down and the percutaneous vertebroplasty requires height to the patient not having, and increases puncture time and mortality, increases the risk of damaging adjacent tissue.
In the prior art, generally adopt Kirschner wire location, free-hand puncture under perspective again needs repeatedly positive side position perspective manually to adjust point of puncture and angle down, makes the amount of radiation that venipuncture difficulty is big, accuracy is not high, increased operator and patient.And there are some defectives in existing locating guide device from designing, and what have can only locate in normotopia; What have can only the determining section parameter, can not the three-dimensional localization guiding; Can three-dimensionally lead in the design that has, but can not locate, positive side position perspective can not be connected, and be difficult in practical operation, realize; What have can not fixed guide, and can mobile cause deviations, the employing that has in the use is that positioner is fixed on the sclerotin, is to have wound fixing, increases patient's wound.Therefore, if can provide a kind of three-dimensional localization guider of avoiding above-mentioned defective, can locate fast, accurately guiding can improve the puncture accuracy greatly, shortens operating time, reduces operator and patient's x-ray dose.
Be CN2776327Y " percutaneous vertebral body puncture locating guide device " as notification number, this guider comprises two groups of guiding mechanisms, and the adjustment process of every group of guiding mechanism is finished separately, and complicated operation makes operating time longer.Every group of guiding mechanism comprises a plurality of connecting rods that are hinged, and hinge is more, makes the locking of guiding mechanism unreliable, and locatees inaccurate.This guider has only a measuring device support bar, and one-time positioning can only puncture at two places, and efficient is lower.The slide block of this guider does not have the stopping means of vertical direction, and in operating process, guider landing from the measuring device support bar easily strengthens the risk of operation.This guider need bring misery to the patient, and need contact with patient's body from three spinal columns that are positioned the patient, and patient's body moves and makes the location inaccurate.
