Description
Technical field
This utility model belongs to the improvement to operating theater instruments, and the full Microendoscopic percutaneous intervertebral disc operation fibrous ring be especially applied in minimally invasive spinal surgery field of surgery is sewed up.
Background technology
According to national health department's statistics, China intervertebral disk hernia patient is always in rising trend for many years, and is expanded to person between twenty and fifty by person in middle and old age with surprising rapidity year by year.This sick modal reason is that intervertebral disc each several part is as vertebral pulp, fibrous ring and cartilaginous lamina, especially vertebral pulp, after having degenerative change in various degree, under the effect of external force factor, the Anular disruption of intervertebral disc, nucleus pulposus protrudes from rear or intraspinal tube from part of breaking, and causes adjacent nerve roots to be stimulated or oppresses, thus generation pain, a series of clinical symptoms such as numb limbs and tense tendons, pain.Intervertebral disc lacks blood circulation gradually after growing up, and repair ability is poor.On the basis of above-mentioned factor effect, certain can cause intervertebral disc bear the risk factor that pressure raises suddenly, the poor vertebral pulp of elasticity namely may being made through becoming not too tough and tensile fibrous ring, causing Nucleus pulposus.Traditional operation method is excise outstanding vertebral pulp and free fibrous annulus tissue, and to remove the compressing of nerve root, but the drawback of this kind of operation method is that body surface otch is large.Under percutaneous endoscopic, intervertebral disc marrow nuclear excising art (Percutaneousendoscopiclumbardiscectomy) is one of Minimally Invasive Surgery for the treatment of prolapse of lumbar intervertebral disc at present, postoperative pain alleviates compared with conventional open intervertebral disc marrow nuclear excising art (Opendiscectomy), otch is little, go out insufficiency of blood, the advantages such as post-operative hospital stay is short, curative effect is close with open surgery.But no matter be open surgery or Minimally Invasive Surgery, Postoperative recurrent rate is higher is all one of limitation of resection of nucleus pulposus, having scholar to add up even can up to 15%.Have scholar to prove by experiment, the repairing of the postoperative fibrous ring of resection of nucleus pulposus contributes to reducing again outstanding relapse rate.The one of the main reasons of PELD post-operative complication is that the mechanical integrity of failed fibers ring is not repaired, but so far, go back neither one effectively and safety repair failed fibers ring method or equipment at full Microendoscopic.
Utility model content
The technical problem solved
By using full Microendoscopic minimal invasion intervertebral disc operation fibrous ring stiching instrument of the present utility model, smoothly under the Minimally Invasive Surgery narrow surgical visual field and working place, directly outside fibrous ring, Anular incision can be sewed up.
Technical scheme
A kind of full Microendoscopic minimal invasion intervertebral disc operation fibrous ring stiching instrument, comprise shank 1 and needle point 2, be bent into hook-type at described needle point 2, described needle point 2 front end is provided with threading hole 3.
Further, be the difference of cervical vertebra, thoracic vertebra or lumbar vertebra according to surgical object, the transverse width of described hook-type has 1.5mm, 2.0mm, 2.5mm tri-kinds of specifications.
Full Microendoscopic minimal invasion intervertebral disc operation fibrous ring stiching instrument of the present utility model, its threading hole 3 is circular or oval.
Beneficial effect
Effective fibrous ring having sewed up incision in operation, para-position is accurate, the technical problem that after solving intervertebral disc Minimally Invasive Surgery, fibrous ring is sewed up smoothly, decreases because para-position is forbidden to have the postoperative complication of nerve and blood vessel near impact simultaneously.

Detailed description of the invention
This description for the full Microendoscopic minimal invasion intervertebral disc operation fibrous ring stiching instrument of cervical operation, describes structure of the present utility model and detailed directions in detail:
As shown in Fig. 1 (a), stiching instrument adopts stainless steel material, and wherein 1 is shank, and 2 is needle point, and 3 is the hole on needle point, and the shape in this hole is circular or oval, for reaching the technique effect mated with cervical vertebra, the transverse width of hook-type is designed to 1.5mm.As shown in Figure 2, in minimal invasive surgical procedures, first service aisle 6 is set up, after vertebral pulp is disposed, by the hole 3 of absorbable thread through needle point front portion, then stiching instrument is entered service aisle 6 together with two lines, by endoscope to determine that it arrives the breakage of fibrous ring 5, apply the benefit of absorbable thread herein for taking out stitches, tissue antigen rejection is low, ensures the length long enough of line simultaneously.As shown in Figure 3, do needle point from inside to outside through the stitching action of damaged fibrous ring side, needle point exposes together with two lines from fibrous ring.As Fig. 4, Fig. 5, shown in Fig. 6, pin hole 3 and two lines are below certain about at Microendoscopic, single line after using elongated clamping device 7 to clamp pin hole, this line is extracted out from pin hole, then along the region that service aisle will be convenient to operation outside this root tape to service aisle, now, wireless in the pin hole of stiching instrument front end, again the needle point of stiching instrument is exited from aforesaid fibrous ring tube wall, also the region be convenient to operation is got back to along service aisle, outside service aisle, now there are two the end of a thread, one is stationary end outside always, one is the end of a thread end passed over from fibrous annulus tissue with elongated clamping device 7, stationary end is penetrated in stiching instrument pin hole, by service aisle, needle point is delivered to fibrous ring breakage, by stiching instrument from inside to outside through the opposite side of fibrous ring breakage, needle point exposes together with line from fibrous ring, that root free in two lines exposed after clamping pin hole with elongated clamping device 7 again, equally it is extracted out from pin hole, bring it to elongated clamping device 7 region be convenient to operation outside service aisle simultaneously, exit stiching instrument wireless in pin hole.As shown in Figure 7, now two the end of a thread of absorbable thread are all outside service aisle, but have been each passed through the relative two side of fibrous ring, outer by two the end of a thread knottings at service aisle, then are pushed to fibrous ring outside after being fixed by toe-in with knotting propeller.
Adopt stiching instrument of the present utility model, damaged fibrous ring is sewed up when can be conveniently implemented in intervertebral disc Minimally Invasive Surgery, fibrous ring is sewed up closely, skin and muscular tissue is cut on a large scale, simultaneously due to the involutory postoperative complication closely decreased because of neural near involutory bad impact and blood vessel without during routine operation.
Although embodiment of the present utility model is cervical vertebra, for thoracic vertebra and lumbar vertebra, compared with cervical vertebra, just cone is relative with the volume of fibrous ring increases, therefore the corresponding expansion of the lateral separation of stiching instrument front end hook-type, is respectively 2.0mm or 2.5mm, and its structure is similar to cervical vertebra stiching instrument with usage.
More than detailed description of the invention more of the present utility model; but this utility model is also not only confined to aforesaid way; all simple transformation to this utility model technical characteristic; such as constituent material is become other metals, pin hole from circle, elliptical deformation diamondwise, crotch-shaped is become semicircle, triangle, rhombus from hook-type from rustless steel, all will fall within protection domain of the present utility model.
