Abstract
The invention relates to a medical appliance, in particular to a puncture location device for a minimal invasive lumbar surgery. The puncture location device comprises a locating ring, a locating needle and a puncture needle, wherein the locating ring is a fan-shaped device with a central angle of 105 degrees; a plurality of locating reference holes are formed at equal intervals in the locating ring; a depth control locking device is arranged at the tail end of the locating ring; the locating needle can penetrate through the depth control locking device and is fixed to the locating ring; the locating needle comprises a locating rod and a fixing rod; a needle head is arranged at one end of the locating rod; and the fixing rod is transversely and uniformly provided with concave rings. The puncture location device for the minimal invasive lumbar surgery is accurate in location and short in locating time.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of minimal invasive lumbar surgery puncture positioning device。
Background technology
Prolapse of lumbar intervertebral disc is the common cause of lumbago and skelalgia, is clinical common disease, and traditional therapy easily recurs and long term complication is more。The Therapeutic Method of prolapse of lumbar intervertebral disc except operation and expectant treatment except, minimally-invasive treatment be after develop direction。Use the accuracy that it is critical only that Needle localization of minimally-invasive treatment prolapse of lumbar intervertebral disc and the safety of therapeutic process。
At present, when positioning puncture in minimal invasive lumbar surgery, begin to learn the first step difficult point of doctor: use softer guiding pin to puncture from waist side rear, according to certain angle demand, be placed into superior articular process of lumbar vertebra position, then place service aisle at different levels；In the process, location generally will take for 40 minutes to 150 minutes, and patient is painful, it is difficult to adheres to prolonged operations, and puncture position is likely to undesirable, increases operating difficulty。And when positioning inaccurate, need to carry out repeated localised puncture, not only easily cause operation unexpected, also improve the probability that postoperative complication (hemorrhage, infection, gap turn narrow, nerve injury etc.) occurs, additionally, because repeated localised puncture brings ray frequently to throw photograph, patient and doctor are caused injury difficult to the appraisal, how to improve the positional accuracy that minimal invasive lumbar surgery punctures, become this area and be badly in need of solving the technical problem that。
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of accurate positioning and the minimal invasive lumbar surgery puncture positioning device that positioning time is short。
For realizing object above, the present invention is achieved by the following technical programs:
A kind of minimal invasive lumbar surgery puncture positioning device, including centring ring, positioning needle and puncture needle；Described centring ring is central angle is the fan-shaped device of 105 °, and centring ring is placed equidistant some location reference bore, and centring ring end arranges limited deep locking device, and described positioning needle may pass through the deep locking device of limit, is fixed on centring ring；Described positioning needle includes location bar and fixing bar, and bar one end, location is syringe needle, and fixing bar is laterally homogeneous is provided with scrobicular ring。
Further, described location reference point aperture is 4mm, and limitting deep locking device aperture is 6mm。
Further, described positioning needle syringe needle is provided with one layer of erosion shield。
Further, the pin length of described positioning needle is 140mm, and the location bar trans D of positioning needle is 3mm, and the fixing bar trans D of positioning needle is 6mm。
The invention provides a kind of positioning time short, the minimal invasive lumbar surgery puncture positioning device of accurate positioning, can effectively shorten the Needle localization time within 5min；Positioner is to utilize concentric circular principle, makes positioning needle syringe needle and puncture needle needle point point to same focus all the time, thus improve the degree of accuracy of location；And this device is easy to use, after fixing positioning needle, according to intervertebral disk hernia position, by puncture needle security protection on centring ring, it is achieved quick and precisely position。By this device, it is also possible to complete " percutaneous intervertebral disc cuts breath art ", " vertebral compression fracture minimally invasive centrum plasty "。
