Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of fibrous ring plugging device.
Background technique
Resection of nucleus pulposus is one of common surgical intervention means, which is intended to the vertebra by extracing prominent, pressuring nerve
Disc tissue alleviates symptom, and surgical effect is good, but still the patients surgery for having 20%-25% or so is ineffective.Wherein
Most important reason is postoperative recurs.
Since fibrous ring blood supply is limited, self-repairing capability is very weak.It studies and has confirmed, the simple nucleus pulposus of interverbebral disc
The risk for extracing postoperative recurrence is related with the size of fibrous ring defect, and fibrous ring defect range is bigger, and Postoperative recurrent rate is higher.
Carragee etc. points out that fibrous ring defect width is more than 6mm2When, the postoperative rate that protrudes again is 27.3%, and other types interverbebral disc
Prominent patient's Postoperative recurrent rate is only 4.8%.Fibrous ring defect area is greater than 54mm2The re-treatm ent rate of patient's postoperative recurrence be
18%, and defect is less than 36mm2Re-treatm ent rate be only 4.7%.Re-treatm ent patient clinical is effect improved and final result is often not so good as
Initial surgery.Currently, clinically still lacking effective means processing fibrous ring defect.
Currently, American-European countries handles fibrous ring defect, Barricaid master using the medical instrument of Barricaid a kind of
To include the titanium anchor of lower section and the network polymers of top, the titanium anchor of lower section is inserted into the sclerotin of the next centrum when use,
Network polymers is opened in the intervertenral space at fibrous ring breach after Nuclectomy.The instrument there are the problem of have: 1, titanium anchor
There is certain destruction to the next vertebral fracture, more has implantation material abjection is may to sufferers of osteoporosis face；2, titanium anchor and network polymerization
It is connected between object with joint, fatigue, the possibility of fracture is inevitably had after applying for a long time；3, Barricaid is solid forms, and
It needs to be placed in titanium anchor in the next centrum sclerotin, traditional Nucleus resection application problem is little, but can not apply when Minimally Invasive Surgery；
4, can network polymers be tightly combined with fibrous ring breach, and there is presently no too many correlative studys.
