Description
Technical field
The invention patent relates to a kind of complete interior stitching devices of tissue repair, realization tissue damage that can be simple and efficient
Suture in complete.
Background technology
Meniscus injury is the damage of common motion of knee joint, therapy according to damage location, range, 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 place, 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, more and more evidences
Support the meniscus for retaining periphery rupture, meniscus is in joint nutrition, lubrication, stabilization, load transmission, buffering, this body-sensing in addition
Effect in terms of feel and prevention osteoarthrosis, repairs the rupture of meniscus periphery, retains meniscus 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 possible
Lower meniscus sutures, it has also become the main method of meniscus injury treatment.
Two sewing needles for being connected with suture can be inserted into tissue by traditional arthroscope lower meniscus suture, surgeon
Portion passes a suture through the wound site of organization internal, suture knots fix within the organization.Meniscus injury sewing method
There are mainly three types of：Outside-interior suture；Interior-outer suture and complete interior suture.Outside-interior suture the advantages of be that notch is small, be not necessarily to special-purpose device
Tool is suitable for meniscus anterior angle and tears；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 suture is that notch is small in complete, is not necessarily to special-purpose device
Tool, the visual field is good, safe and simple, convenient and efficient, is suitable for half a month board body part and relief angle sutures.
Meniscus suture is required for additional notch by the way of interior-outer or outer-interior, to avoid neural blood vessel damage also
Need to detach institutional framework, and it is also possible to cause capsular ligament contracture, limitation of activity, neuroma row at.Due to
Excessive tissue has been ligatured in suture knots, and it is not good enough to also result in suture tension.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.
Currently, 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,Equal products, generally existing are fixed
The problems such as nail individual is big, easily deviates from, and is easy to cause secondary injury to tissue, and doctor can not puncture again.

In the outer one end of needle needle tray far from needle point, as shown in Figure 7.
In use, determining required depth with meniscus depth probe first, depth restriction pipe is adjusted to outside joint
Required length can refer to the graduation mark of outer needle needle point as reference, and depth limits pipe without taking out, and taking-up can cause suture to relax
With prefabricated knot suture " tangling ".Depth limits pipe and also can be used as the use of slot casing, can reduce scraping of the fat pad to implantation material,
Help sewing needle in the positioning of intracavitary, application method is to pin the deep sliding block of limit to cross outer needle needle point up to depth limits pipe, is sutured
Device enters along slot casing in articular cavity, and casing can be removed after sewing needle enters joint, limits deep sliding block and repositions limit
Depth continues to use as depth restriction pipe.
After the outer needle of the stitching devices of the invention enters joint, outer needle is located in the upper of tear portion under arthroscope
Side, distance tearing edge about 5mm, outer pin puncture meniscus in place after, the push rod on driving handle, push rod connection interior needle push
First holdfast is moved to outside needle point, as shown in figure 8, push rod " " the first holdfast is released after sound, unclamping push rod makes push rod reset,
The positioning of the first holdfast is completed, as shown in Figure 9；Outer needle is repositioned to the lower section at tearing position under arthroscope, is stitched at this time
Zygonema tears edge about 5mm perpendicular through wound, entry point distance, after puncturing meniscal tissue in place, pushing away on driving handle
The interior needle of bar, push rod connection pushes the second holdfast to be moved to outside needle point, as shown in Figure 10, push push rod " " the is released after sound
Two holdfasts complete the positioning of the second holdfast, as shown in figure 11；After the excitation of second holdfast, 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 closes wound.Free end is passed through into knot thread cutter and tightens suture, finally pushes trimming
Device top shoe completes trimming action, that is, completes the complete interior suture of meniscus.
