Description
Technical field
Patent of the present invention is related to a kind of complete interior stitching devices of tissue repair, can realize tissue damage with simple and efficient
Sutured in complete.
Background technology
Meniscus injury is the damage of common motion of knee joint, its treatment method according to damage location, scope, type and
It is different.Such as expectant treatment, ablation, total resection, suture prosthetic, meniscus prosthetic displacement technique, allogeneic meniscus
Transplantation, engineered reconstruction etc., respectively there is each applicable part, clinically generally use arthroscope lower meniscus resection and half
Month plate suture and neoplasty.Now, it is increasingly recognised that the importance of meniscus biomechanical function, increasing evidence
Support retain periphery rupture meniscus, in addition meniscus joint nutrition, lubrication, stably, load transmit, buffering, this body-sensing
Effect in terms of feel and prevention osteoarthrosis, the rupture to meniscus periphery are repaired, and retain first quarter moon plate shape as far as possible
State, function and biomechanics characteristic, have become the standard for the treatment of.At present in the case where clinical setting allows, arthroscope is carried out as far as possible
Lower meniscus sutures, it has also become the main method of meniscus injury treatment.
Traditional arthroscope lower meniscus suture, surgeon can insert two sewing needles for being connected with suture in tissue
Portion, the wound site of organization internal is passed a suture through, suture knots in tissue and fixed.Meniscus injury sewing method
Mainly there are three kinds：Outside-interior suture；Interior-outer suture and complete interior suture.Outside-interior suture the advantages of be that otch is small, without special-purpose device
Tool, torn suitable for meniscus anterior angle；Interior-out-seam is properly used for relief angle and the outside of meniscus, and the visual field is good, and operation is more convenient,
But since it is desired that posterior incisions, damage the risk for hindering neurovascular structure；The advantages of being sutured in complete is that otch is small, without special-purpose device
Tool, the visual field is good, safe and simple, convenient and swift, is sutured suitable for first quarter moon board body part and relief angle.
Meniscus suture is required for extra otch by the way of interior-outer or outer-interior, to avoid neural blood vessel damage also
Need to separate institutional framework, and it is also possible to cause capsular ligament contracture, limitation of activity, neuroma row into.Due to
Excessive tissue has been ligatured in suture knots, it is not good enough to also result in suture tension force.Sewing method can be in no neural blood vessel in complete
Horizontally or vertically formula mattress suture is carried out under the risk of damage, is provided for doctor that firm, repetition has been given birth to, credible and time saving
Meniscus repair technology.
At present, the meniscus sewing system of Clinical practice has easy to operate, the advantages, wherein meniscus spiral shell such as development is fast
Nail, meniscus arrow are most popular meniscal repairs methods, but external biological mechanics study shows that its fixing intensity is relatively low.
Existing meniscus stitching unstrument has Meniscal CinchTM, SEQUENTTM,Deng product, generally existing is fixed
The problems such as nail individual is big, easily abjection, easily causes secondary injury to tissue, and doctor can not puncture again.

In the present embodiment, outer pin as shown in figure 4, interior pin as shown in figure 5, interior pin is placed in inside outer pin, outer pin is placed in depth
Degree is limited in pipe, and it is as shown in Figure 6 that depth limits pipe.First holdfast is completely disposed in the hollow tube chamber of outer pin, the positioning of the second holdfast
In the outer one end of pin needle tray away from needle point, as shown in Figure 7.
In use, depth restriction pipe, is adjusted to by depth needed for being determined first with meniscus depth probe outside joint
Required length, the graduation mark of outer pin needle point is referred to as reference, depth limits pipe without taking out, and taking-up can cause suture to relax
With prefabricated knot suture " tangling ".Depth limits pipe and can also used as slot sleeve pipe, can reduce scraping of the fat pad to implant,
Positioning of the sewing needle in intracavitary is helped, application method is to pin the deep sliding block of limit to cross outer pin needle point up to depth limits pipe, is sutured
Device enters in articular cavity along slot sleeve pipe, is removable sleeve pipe after sewing needle enters joint, limits deep sliding block and reposition limit
Deep degree continues to use as depth restriction pipe.
After the outer pin of the stitching devices of the invention enters joint, outer pin is positioned at the upper of tear portion under arthroscope
Side, distance tear edge about 5mm, outer pin puncture meniscus in place after, the push rod on driving handle, push rod connection interior pin promote
First holdfast moves to outside needle point, as shown in figure 8, push rod " " the first holdfast is released after sound, unclamping push rod resets push rod,
The positioning of the first holdfast is completed, as shown in Figure 9；Outer pin is repositioned to the lower section at tear position under arthroscope, now stitched
Zygonema tears edge about 5mm perpendicular through wound, entry point distance, after puncturing meniscal tissue in place, pushing away on driving handle
Bar, the interior pin of push rod connection promote the second holdfast to be moved to outside needle point, as shown in Figure 10, promote push rod " " the is released after sound
Two holdfasts, the positioning of the second holdfast is completed, as shown in figure 11；After second holdfast excites, stitching unstrument can take out out of articular cavity.Seam
Clutch exposes the free end of preset Slipped Clove Hitch suture, the first anchor can be shortened by pulling the free end of suture after intracavitary taking-up
Distance between nail and the second holdfast, close wound.Suture through knot thread cutter and is tightened up into free end, finally promotes trimming
Device top shoe, trimming action is completed, that is, completes the complete interior suture of meniscus.
In the present embodiment, the outer needle set of complete interior stitching devices has certain radian, in other embodiments, can also use straight
The outer pin of line style, meet the needs of meniscus multi-angle suture.
