Description
Technical field
This utility model relates to medical instruments field, particularly relates to positioner under a kind of foramen intervertebrale lens.
Background technology
Prolapse of lumbar intervertebral disc is one of orthopaedics common disease; Foramen intervertebrale lens surgical technic occupies more and more consequence in Wicresoft's intervertebral disc operation, and it is little that this technology has wound, recovers fast, few intercurrent disease, the advantages such as determined curative effect, economy, safety.Percutaneous foramen intervertebrale lens has one of difficult point and emphasis to be puncture technique, percutaneous foramen intervertebrale lens technological learning curve is longer, operation abecedarian does not often possess good three-dimensional imaginative power and clinical puncture procedure experience, the palm palm causes operation to carry out smoothly, operating time is caused to extend, corrective surgery pain increases, and patient and operative doctor x-ray Exposure increase, and even cause operative failure.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide positioner under a kind of foramen intervertebrale lens, and this positioner can improve accuracy and the success rate of the empty localised puncture of lumbar intervertebral foramen, reduces patient and patient's x-ray radiation amount, shorten operating time, reduce complication after puncture.
In order to realize above-mentioned object, this utility model have employed following technical scheme:
Positioner under a kind of foramen intervertebrale lens, comprises arc-shaped slide rail, localizer and guider; Described guider comprises the hollow guide pipe for placing puncture needle, and the end of arc-shaped slide rail is provided with slide rail guide part, and arc-shaped slide rail is fixing on the guides by slide rail guide part; The subscript of described arc-shaped slide rail is provided with angle, and the middle part of arc-shaped slide rail offers cambered way, and localizer is slidably arranged in cambered way; Localizer comprises the hollow positioning pipe for placing Kirschner wire, and is arranged on the positioning tooth on hollow positioning pipe inner end, and is arranged on hollow positioning pipe outer end knocks end.
As preferably, the positioning tooth on localizer is in the arc opening of arc-shaped slide rail, knocks end and is in outside the arc opening of arc-shaped slide rail.
As preferably, described localizer is slidably arranged in cambered way by adjusting device, and adjusting device comprises the slide mass be socketed in outside arc-shaped slide rail, and for locking the clamping screw of slide mass; During use, clamping screw can be unscrewed, the slip of manual operation slide mass and localizer.
As preferably, slide rail guide part is semicircle hollow sleeve, and the inner side of slide rail guide part is also provided with abrasionproof internal layer, and abrasionproof internal layer is threaded on the outer side surface of hollow guide pipe.
This utility model adopts technique scheme, under this foramen intervertebrale lens, positioner needs to be had an X-rayed down by C arm machine to determine lumbar intervertebral joint superior articular process's head end in the preoperative, localizer percutaneous in this device is inserted Kirschner wire to articular process head end, and knock localizer by hammer knock end, make it be fixed on articular process place; Then according to foramen intervertebrale lens technology determination entry point, and regulate this device, the guider in device is made to aim at entry point, puncture needle in guiding position from the inserting needle pricking method determined to articular process source, fastening nut, get and determine angle value and corresponding intervertebral foramina coronal plane angularity is close, take out Kirschner wire, remove sight.In sum, under this foramen intervertebrale lens, positioning device structure is reasonable, easy to operate, by two one line principles, on the basis determining entry point, determines articular process upper end fast, and determines inserting needle route; Thus improve accuracy and the success rate of the empty localised puncture of lumbar intervertebral foramen, reduce patient and patient's x-ray radiation amount, shorten operating time, reduce complication after puncture.
