Technical field
The present invention relates to the field of medical instrument technology, predominantly establish bone caused by the removal lesion tissue of channel through bone
The prosthetic device in channel, specifically a kind of bone channel obturator.
Background technique
Cervical Disk Herniation is clinically relatively conventional one of spinal disease, and morbidity is only second to protrusion of lumber intervertebral disc.It is main
If due to cervical intervertebral disk nucleus pulposus, fibrous ring, cartilage plate, especially nucleus pulposus, after different degrees of retrogression pathological changes occur, outside
Under the action of boundary's factor, annulus fibrosus disci intervertebralis is caused to rupture, nucleus pulposus is prominent from rupture place or deviates from intraspinal tube, to make
Cause headache, dizziness such as spinal nerve root and compression of spinal cord at adjacent tissue；It is palpitaition, uncomfortable in chest；Neck acid is swollen, limitation of activity；
Shoulder back pain, upper limb numbness distending pain；The sings and symptoms such as gait unstability, weakness of limbs occur high paraplegia and jeopardize when serious
Life.
For herniation of cervical disc, therapeutic modality is broadly divided into conservative therapy and operative treatment, and conservative therapy includes
Drug, physical therapy etc. have certain effect to the state of an illness is alleviated.But when conservative therapy is invalid, when especially the state of an illness is heavier, operation is controlled
It treats and often can get satisfactory effect；Preceding road is treatment central type and other central herniation of cervical intervertebral disc through the full endoscopic technic of centrum
A kind of modus operandi, the structural schematic diagram for preceding road through the full endoscopic technic of centrum as shown in Fig. 10, surgical procedure are as follows: with
Preceding road minimal invasion mode establishes bone channel to prominent nucleus pulposus position adjacent to centrum drilling from pathological interspinal disk, and placement operation is logical
Road connects surgical endoscope, in direct view under endoscope using the disc tissue at nucleus pulposus clamp cleaning vertebral bone channel rear, extracts outstanding
Nucleus pulposus disc tissue.The art formula forms vertebral bone channel after centrum drills, this is to the postoperative centrum mechanical strength of patient and steady
It is qualitative to generate a degree of influence, have patient be filled with into vertebral bone channel tricalcium phosphate supporter and autologous spongiosa bone into
Row support is repaired.
Tricalcium phosphate supporter is applied in a kind of Intrapyramidal eyelid retractor, is as shown in Fig. 11 tricalcium phosphate supporter
Structural schematic diagram, in use, be implanted into vertebral bone channel as branch erect support firm effect, autologous spongiosa can be inserted
Bone promotes knitting, but tricalcium phosphate supporter volume is larger and size is fixed, and can not be implanted into vertebra by scope invasive manner
