Description

A kind of elastic thread cord holder

Technical field

The utility model relates to medical facilities (consumptive material) correlative technology field, in particular to a kind of elastic thread cord holder.

Background technique

The most commonly seen disease of anorectum department has: mixed hemorrhoid, anal fistula, perianal abscess, anal fissure.Although disease is different, art In a most indispensable operation --- ligation, suture used is mostly non-absorbable silk thread in ligation operation.

Although silk thread ligation is operated in most commonly seen art, non-easy thing is operated in anal-surgery.Reason has three: One, the reason of operation of anorectum department is because of anatomical structure, ligation operation are mostly to operate under non-direct-view, belong to deep part knotting, operation is not Easily；Two, it is ligatured in anorectum department art, because ligation tissue is more, therefore opposite ligation site tissue tension is larger, when ligaturing first knot It easily loosens, causes ligation not tight, cause ligature surprisingly to fall off, situations such as big bleeding occur；Three, due to ligaturing tissue in art More, after partial ligation tissue necrosis, ligation site tissue attenuates, and ligation point tension reduces therewith, therefore easily causes the later period Ligation tissue necrosis is incomplete, and ligature does not fall off or falls off situations such as incomplete for a long time.

In addition to ligaturing operation, there are also a kind of distinctive operation-ligating method for treating anal fistula is generally usually used in height in anorectum department operation Position anal fistula or high perianal abscess.Principle are as follows: with the rubber ring (generally using the rubber ring of sterile rubber gloves collar extension) of tightening Slowly cutting muscle etc. tissue, play the role of protecting anus include about function, prevent bleeding.But during actual therapeutic, often The ligation later period can be encountered since partial ligation tissue has been turned off, ligation site tissue attenuates, therewith opposite of ligation point cushion rubber Power reduces, and the dynamics slowly cut is not achieved, therefore needs to tighten rubber ring again.Tightening cushion rubber operation again, needs mostly Injection local anaesthesia drug is uncomfortable with the rectal tenesmus of reduction of patient, pain again before operation, to patient bring greatest fear and Pain.

Therefore, it during actual operation, has invented and a kind of has been made of cored elastic thread by special knot tying fashion The method cut at the polycyclic elastic force constraint slip-knot of single set.

Among cored elastic thread parallel for several elastic force rubber bands (rubber), surface is wrapped by fabric (polyester fiber), in this way Design feature both maintained the telescopic resilience of elastic force rubber band；The wrapping of fabric can control the excessive tensile of elastic force rubber band again, prevent The only effect that elastic force rubber band tension reduces or is broken after excessive tensile, while increasing the intensity of elastic thread；Further more, fabric is vertical The wrapping of traversed by mistake, increases the skin-friction coefficient of cored elastic thread, and ligation point is not easy to slip after ligation, and knot is not easy pine It is de-.

So-called single polycyclic elastic force of set fetters slip-knot, and knotting method is as shown in Figure 1, i.e. multiple elastic force ring constraints are squeezed and worn Elastic thread more therebetween, make across elastic thread constraint position narrow, and both ends are relatively thick, squeeze and the change of form makes to rub It wipes power to become larger, fixes the elastic thread passed through, be not easy to slip.When specific operation, suitable number of rings can be selected according to actual needs, 1 The dynamics of the opposite constraint of ring is not good enough, and retraction is easy when ligaturing tension, and ligation ring dynamics reduces；4 ring phases to the dynamics of constraint too Greatly, operating difficulties when stringing, and be easy to break elastic thread；According to practical operation experience, the opposite constraint dynamics of 2 rings, 3 rings is moderate, Stringing operation is also easy, and 2 rings are more suitable for ligaturing the less operation of tissue, and 3 rings are more suitable for ligaturing the more operation of tissue.Therefore it is practical 2 rings, 3 rings are more suitable for when ligation operation, and 3 ring lists cover polycyclic elastic force and fetter slip-knot (i.e. elastic force coil) knotting method such as Fig. 1 institute Show, it is as shown in Figure 2 that 3 ring lists after knotting cover polycyclic elastic force constraint slip-knot (i.e. elastic force coil).The knotting method of other number of rings with This is similar, therefore no longer excessively repeats.

But certain utensil is needed to carry out compounding practice in actual use, to reach fixed elastic force knot while again The purpose that easily elastic thread stringing end can be shunk.

Summary of the invention
