Foramen reaming tool used during transforaminal approach surgery under spinal endoscope

Abstract

The invention discloses a foramen reaming tool used during a transforaminal approach surgery under a spinal endoscope. The foramen reaming tool comprises at least one bone awl, at least one bone awl protective sleeve, a plurality of bone drills and at least one bone drill protective sleeve; each bone awl comprises a bone awl rod, a rotating handle and an awl head, the rotating handle is arranged at the tail end of the bone awl rod in a connected manner, the awl head is fixedly arranged at the head end of the bone awl rod, the bone awls include a first bone awl, and an awl head of the first bone awl is in the shape of a triangular pyramid; each bone drill comprises a bone drill rod, a rotating handle and a drill bit, the rotating handle is arranged at the tail end of the bone drill rod in a connected manner, the drill bit is fixedly arranged at the head end of the bone drill rod, and a through wire guide hole is arranged in the axial center of the bone drill; and the multiple bone drills at least include first bone drills and large-diameter bone drills, and outer diameters of the drill bits of the first bone drills and the large-diameter bone drills are sequentially increased. The foramen reaming tool has the advantages of reasonable design, capability of improving surgical safety, and the like.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to an intervertebral foramen reaming tool in transvertebral foramen approach surgery under the spinal endoscope. Background technique [0002] Lumbar intervertebral herniation (intervertebral disc herniation compresses the nerve, and the nerve is compressed by the intervertebral disc tissue, which is soft tissue), lumbar spinal stenosis (bone hyperplasia causes relatively narrow nerve passages and causes entrapment symptoms, and the nerve is compressed by bony tissue, which is hard tissue). tissue) is a common disease that has plagued patients for a long time. Most of the current treatment methods use open surgery, that is, posterior lumbar surgery, incision of the skin, peeling off the muscles, resection of the lumbar lamina, and resection of the protruding intervertebral disc tissue or hyperplastic bone tissue that compresses the nerves (surgical decompression). Surgical trauma i...

Problems solved by technology

[0003] However, the technical difficulty of this operation is accurate puncture positioning. The puncture needle must be close to the articular process wall. This problem makes clinicians spend a lot of time for accurate puncture and undergoes dozens of X-ray fluoroscopy positioning, causing serious harm to patients and doctors. Huge damage, moreover, using circumcision to resect the superior articular process may easily cause accidental injury to important soft tissues such as nerves and blood vessels around the circumference, and cause serious complications such as lower limb muscle paralysis and hemorrhage. Therefore, it is necessary to design some surgical tools to improve this method. technology
