Description
Technical Field
The utility model belongs to the technical field of auxiliary medical apparatus, concretely relates to supersound guide intervertebral foramen mirror puncture expansion stack cover.
Background
Lumbar intervertebral disc protrusion (LDH) is mostly generated on the basis of lumbar intervertebral disc degeneration, aseptic inflammation and immune inflammation are caused by nucleus pulposus tissue protrusion caused by rupture of fibrous rings, and spinal nerve root lesion is caused by mechanical compression of the protruded nucleus pulposus tissue, so that lumbago is accompanied by unilateral or bilateral lower limb radioactive pain and nerve dysfunction. Common treatment methods include conservative treatment, minimally invasive treatment, open surgery treatment and the like. As one of minimally invasive treatments, the transforaminal endoscopic surgery has obvious advantages in the aspects of traumatism, safety, complications and the like compared with the traditional surgery mode, and is rapidly developed in recent years. The success of the foraminoscopic procedure depends on whether the working cannula is placed at the target site under imaging guidance. The commonly used puncture guiding methods are X-ray and CT, but the above guiding methods have the problems of X-ray radiation, incapability of real-time guiding and the like. The ultrasound-assisted technique has unique advantages in the above aspects, and is gradually paid attention by operators. The existing transforaminal endoscope puncture and expansion set originally aims at facilitating the guidance under X-rays, cannot reflect the specific needle insertion depth in an ultrasonic image, only can display the plane where a puncture needle is located, and has no reference mark on an acoustic image. If the needle is inserted too deeply or too shallowly, the puncture position is not good at a light rate, and unnecessary damage (nerves and organs) may be caused at a heavy rate. Based on this, the utility model relates to an supersound guide intervertebral foramen mirror puncture expansion stack solves above-mentioned problem.
