Specific embodiment
A specific embodiment of the invention is further described with reference to the accompanying drawing.
In Fig. 1, including elastic thread 101, elastic thread work department 1011, elastic thread freedom portion 1012, inelastic suture102, sewing needle 103, tie point 104 etc..
As shown in Figure 1, the present invention is a kind of medical elastic cable architecture, including inelastic suture 102, the inelastic seam102 one end of zygonema connects sewing needle 103, and elastic thread 101 is in its natural state with inelastic suture 102 with row, and elastic thread101 are connected with inelastic suture 102 by two tie points 104, the elastic force between two tie points 104 under natural conditionsThe length of line 101 is equal to or slightly less than the length of inelastic suture 102, correspond on elastic thread 101 two tie points 104 itBetween part formed elastic thread work department 1011.
Elastic thread 101 is guided by inelastic suture 102 with row with elastic thread 101 by using inelastic suture 102Realize operation when smooth threading operation, this mode efficiently solve directly adopt in the prior art elastic thread 101 thread whenExisting threading and the problem of knotting, but from effect, this mode there exists a further problem in that, thread operation in operationWhen, tie point of the elastic thread 101 close to 103 side of sewing needle forms larger resistance between tissue, influences to thread efficiency.
In order to effectively improve threading efficiency, product of the present invention additionally provides further prioritization scheme: elastic thread 101 is also wrappedElastic thread freedom portion 1012 is included, one end of elastic thread freedom portion 1012 is drawn from adjoining tie point 104, elastic thread freedom portion1012 other end extends at sewing needle 103, and is connected with sewing needle 103.By by elastic thread 101, inelastic sutureBoth lines 102 are connected with sewing needle 103 simultaneously, so that operation threading smooth, when effectively reducing the threading of sewing needle 103Resistance, effectively improve operation threading efficiency.When due to operation, elastic thread 101, the length of inelastic suture 102 are longer, oftenA needle is sutured to be required to pull the end of a thread walking relatively long distance, the space that procedure efficiency also further increases.
In order to further increase operation threading efficiency, product of the present invention additionally provides following prioritization scheme: in elastic thread101, the both ends for the system that inelastic suture 102 is constituted are separately connected a sewing needle 103.It include a variety of realities under this designApply mode: one, with row, the length of inelastic suture 102 is big for elastic thread 101 under natural conditions and inelastic suture 102In elastic thread 101, the both ends of inelastic suture 102 are connected with a sewing needle 103 respectively；Two, elastic force can also be usedBoth line 101, inelastic sutures 102 one end is connected with a sewing needle 103 simultaneously, and the length of elastic thread 101 is less than nothingElastic force suture 102, the other end of elastic thread 101 are connected with inelastic suture 102, inelastic suture 102 it is anotherEnd connects another sewing needle 103；Three, wherein optimal scheme is, 101 length of elastic thread under natural conditions with it is inelasticThe equal length of suture 102, and the both ends of 102 the two of elastic thread 101 and inelastic suture are separately connected a sutureNeedle 103.In above-mentioned three kinds of schemes, the third scheme is optimal case, resistance when operation threading both can be effectively reduced, togetherWhen due to using both ends simultaneously thread modus operandi, theoretically can will operation threading the time reduce half.
In a particular application, in order to guarantee to realize elastic thread 101 and inelastic suture 102 in operation threading processSeveral tie points 104 can be arranged in synchronous walking again between elastic thread 101 and inelastic suture 102.
Optinal plan that there are many implementations of tie point 104, specifically: bonding knots, woollen yarn knitting.It equally can basisParticular condition in use needs, and multiple connections can be set between elastic thread work department 1011 and corresponding inelastic suturePoint, it should be noted that elastic thread work department 1011 is needed to remain nature, be worked for elastic thread in settingThe case where portion 1011 is provided with multiple tie points needs after threading knotting by elastic thread work department 1011 adjacent twoInelastic suture between a tie point is cut, to realize the effective stress of elastic thread work department 1011.
For convenience in the course of surgery, elastic thread 101 and inelastic suture 102 be also provided with some distinguishing characteristics withAchieve the purpose that conveniently to distinguish both threads.There are mainly two types of: one, elastic thread 101 and no bullet for specific set-up modeBoth power sutures 102 color is different；Two, elastic thread 101 is different with inelastic 102 the two diameter of suture.Two kinds of setting sidesFormula can be used individually, can also be combined with each other, be used simultaneously, it can be ensured that be carried out at the time of surgery, to both threads effectiveIt distinguishes, it is convenient that inelastic suture 102 is identified in threading, knotting and after knotting and inelastic suture 102 is correspondingIt is cut in the position of elastic thread work department 1011.
Sewing needle 103 in the present invention can be needed according to operation using staight needle or looper, inelastic suture 102, bulletThe line of force 101 can need to be specifically included an elastic thread 101 using multiply and cooperated more inelastic sutures according to the actual situation102 uses or more elastic threads 101 are with the inelastic use of suture 102 of unification root or elastic thread 101, inelastic suture 102It is all made of more set-up modes.
Using product of the present invention concrete application scene and it is corresponding use process is as follows: 1, treat vaginal relaxation: routinelyBraiding vagina elasticated net is walked with elastic thread system, target cavity diameter is tightened to, after cutting off sewing needle 103, with the suture at both ends103 dozens of surgeons' knots are fixed, after the completion of knotting, between two points of contact 104 of elastic thread work department 1011 any position detachment withoutStress is transferred on elastic thread 101 by elastic force suture 102, while cutting off extra elastic thread.Note that target cavity at this timeDiameter is exactly to want restorable chamber diameter after colpectasia.When the penis for being more than this chamber diameter enters, elastic thread is stretched expansion, justIt will receive holding for vagina.2, it treats stress incontinence: walking reinforcement and tightening sphincter urethrae position with elastic thread system,Urethral orifice is raised, then knot fixed with method identical with above-mentioned implementation 1 and is handled.
Novel and unique of the present invention, brief and practical, rich in creative and scientific.By facilitating no elastic force to elastic threadSuture, so that walk distribution of the elastic thread between tissue is become simple and easy, at the same also make the surgeons' knot finally fixed operateHas no difficulty.Meanwhile this system can make the building of elasticated net and being uniformly distributed easily and effectively for elastic force, can show idealIt is minimally invasive with amazing impression, women's stress incontinence is performed the operation and treated for vaginal contraction and is of great significance.
