Description
Technical field
The present invention relates to technical field of medical equipment, and in particular to a kind of bifilar monolock knot knotting instrument.
Background technology
The hold of surgical sutures knot is to maintaining wound approximation, ensuring that organization healing is all essential.Knot is released
Serious complication will be caused, operated particularly with the higher suture of some tension force, such as tendon is repaired, and such as knot, which is released, to be caused
Seam failure is, it is necessary to which second operation suture, secondary damage and financial burden are caused to patient.It is clinical in order to avoid knot is released
The fixing of knot is usually ensured using the quantity of increase knot, however as the increase of knot quantity, the volume of knot is inevitable
Increase, knot occupies that space is more big more influence operation technique, and the larger foreign matter agglomerate of knot formation will stimulate immunity of organism to arrange
Reprimand reaction, influences wound healing.
In order to improve the intensity of knot, the number of knot is reduced, in the prior art there is provided a kind of bifilar monolock knot（
Two-strand-overhand locking knot, TSOL）, it is multiple using braiding compared with the four directions knot of 4 unijunction compositions
Close high polymer suture（Fiberwire）When TSOL knot holding intensity it is high by 143%, using polydioxanone suture（PDS）When
The holding intensity of TSOL knots is high by 216%, using dacron suture（Treasure nation）When TSOL knot holding intensity it is high by 118%.As can be seen here
No matter which kind of material, the knot of TSOL knots releases that rate is relatively low, and the holding intensity of TSOL knots is also more stronger than four directions knot.
In addition to TSOL knots can provide more preferable mechanical property, do not increase the volume of knot compared with the knot of four directions, face
Bed is with the obvious advantage.High tension force is born for any required but the tissue repair of few suture number of times（Such as tendon or ligament reparation
Reparation）, this knotting method is there is provided another safer selection.But the knotting instrument that prior art is disclosed is to hold pin
Device and tweezers, if clinical training and good eye hand coordination mating capability without mass efficient, using existing instrument
Accomplishing fluently the knot has certain difficulty.
The clinical application tied with TSOL, being badly in need of a kind of simply and easily knotting instrument of invention can just better meet
The operation of doctor needs.
