打結組成Knotted composition

一種打結機構，特別是一種打結組成。A knotting mechanism, especially a knotting composition.

隨著現代醫療科技越來越發達，對於手術之也跟著要求趨向以小傷口或是微創等為方向發展，不僅可以達到快速良好的傷口的復原效果，也有助於癒後傷疤的消逝及改善。現有技術中，一手術人員利用一手術縫合線縫合傷口時，通常是以手持一縫針連帶該手術縫合線之末端打結，使得使手術縫合線能將一傷口兩側的組織拉緊，並形成一固定結固定該手術縫合線的末端。As modern medical technology becomes more and more developed, surgeries are also required to be developed in the direction of small wounds or minimally invasive procedures. This can not only achieve fast and good wound recovery, but also help to fade and improve scars after healing. . In the prior art, when a surgeon uses a surgical suture to suture a wound, he usually holds a suture needle and knots the end of the surgical suture, so that the surgical suture can tighten the tissues on both sides of the wound and form a A secure knot secures the end of the surgical suture.

然而上述之現有技術中，需靠該手術人員以手部於該手術縫合線纏繞繫綁形成該固定結，繫綁的過程不僅複雜費時，且手術過程中，最講求的就是手術的時程，此時若是以上述的打結手段逐一於該傷口形成複數個該固定結，不僅整體時間冗長無效率，若是不慎沒有妥善繫綁，還容易導致該傷口裂開，影響的患者的復原效率。However, in the above-mentioned prior art, the operator needs to wrap and tie the surgical suture with his or her hands to form the fixed knot. The tying process is not only complicated and time-consuming, but also the most important thing during the operation is the duration of the operation. At this time, if the above-mentioned knotting method is used to form multiple fixed knots on the wound one by one, not only will the overall time be lengthy and inefficient, but if the wound is not tied properly, it will easily cause the wound to dehisce, affecting the patient's recovery efficiency.

The knotted assembly includes anouter tube 10 , aninner tube 20 , abinding wire 30 and aninsurance wire 40 . Theouter tube 10 and theinner tube 20 are both in the shape of a hollow straight rod, and theinner tube 20 is slidably inserted into theouter tube 10. At least a part of theinner tube 20 protrudes from theouter tube 10, wherein , theinner tube 20 axially penetrates an inner tube throughhole 22, and protrudes from at least a part of theouter tube 10. Theinner tube 20 can be further defined as alasso section 21, and the length of thelasso section 21 It can be adjusted through the sliding relationship of theinner tube 20 relative to theouter tube 10 .

該繫綁線材30軸向地穿設於該內管通孔22內，該繫綁線材30的其中一末端為一繫綁線段31，該繫綁線段31穿出該套索段21方向之該內管通孔22，且該繫綁線段31纏繞該套索段21形成有一預套索32。該預套索32包含形成於該繫綁線段31以及該套索段21之間的一緊束圈321以及纏繞於該套索段21上的一纏繞結322。Thetying wire 30 is axially inserted into the inner tube throughhole 22 . One end of thetying wire 30 is atying wire section 31 , and thetying wire section 31 passes through thelasso section 21 in the direction of thelasso section 21 . The inner tube has a throughhole 22, and thetying wire segment 31 is wound around thelasso segment 21 to form a pre-lasso 32. The pre-lasso 32 includes atightening loop 321 formed between the tyingline segment 31 and thenoose segment 21 and a windingknot 322 wound on thenoose segment 21 .

其中，該繫綁線材30的另一末端為一做動線段33，該緊束圈321之大小可以隨著該做動線段33相對該內管20移動而調整；該纏繞結322形成於該套索段21的方式並無限定，本實施例中，該繫綁線段31以一雙圈纏繞後形成一活結的方式於該套索段21上形成該纏繞結322。The other end of thebinding wire 30 is a movingwire segment 33, and the size of the tighteningring 321 can be adjusted as the movingwire segment 33 moves relative to theinner tube 20; the windingknot 322 is formed on the sleeve. The method of therope section 21 is not limited. In this embodiment, the tyingwire section 31 is wound in a double circle to form a slip knot to form the windingknot 322 on thelasso section 21 .

該保險線材40穿越於至少一部份的該預套索32以及該套索段21之間，且該保險線材40與該預套索32的至少一部份之間呈現相互扣勾的樣態。較佳的，該保險線材40之兩端朝向同一個方向延伸，使得該保險線材40的凹折處形成有一環形結構41，該保險線材40透過該環形結構41與該預套索32的至少一部份相互扣勾。更佳的，該保險線材40之兩端皆朝向該做動線段33之方向延伸，使得該預套索32經由該環形結構41扣勾時，可以保留於該套索段21上靠近該外管10的位置。Theinsurance wire 40 passes between at least a part of the pre-lasso 32 and thelasso section 21 , and theinsurance wire 40 and at least a part of the pre-lasso 32 are in a mutually interlocking manner. . Preferably, both ends of theinsurance wire 40 extend in the same direction, so that the recess of theinsurance wire 40 forms anannular structure 41, and theinsurance wire 40 passes through at least one of theannular structure 41 and the pre-lasso 32. Parts interlock with each other. Preferably, both ends of theinsurance wire 40 extend in the direction of the movingwire segment 33, so that when the pre-lasso 32 is hooked through theannular structure 41, it can remain on thelasso segment 21 close to the outer tube. 10 positions.

該保險線材40與該預套索32之間相互扣勾的結構關係，該保險線材40得以展現將該預套索32固定於該套索段21上的特性，使得以該活結呈現的該預套索32可以不易於該套索段21上鬆脫或是滑落，進而避免該預套索32在無法預期的狀況下滑脫。The mutual interlocking structural relationship between theinsurance wire 40 and the pre-lasso 32 allows theinsurance wire 40 to exhibit the characteristics of fixing the pre-lasso 32 to thelasso section 21, so that the slip knot appearsThe pre-lasso 32 can be prevented from loosening or slipping off thelasso section 21 , thereby preventing the pre-lasso 32 from slipping off under unexpected conditions.

請參考圖1至圖4，該保險線材40扣勾於該預套索32的位置並不限定，如圖1中，該保險線材40穿越該纏繞結322的該雙圈，使得該環形結構41可以扣勾於該雙圈，且該保險線材40之兩端皆朝向該做動線段33之方向延伸，如此該環形結構41便可以固定該雙圈於該套索段21上的相對位置。該保險線材40的設置，不僅是可以達到固定該預套索32的作用，於後續該保險線材40以該環形結構41與該預套索32一起形成為一固定結A時，還可以達到增加該固定結A尺寸之效果，其中，該預套索32形成為該固定結A之步驟以及特徵將進一步於後續詳述。Please refer to FIGS. 1 to 4 . The position where theinsurance wire 40 is hooked on the pre-lasso 32 is not limited. In FIG. 1 , theinsurance wire 40 passes through the double turns of the windingknot 322 , so that theannular structure 41 It can be hooked on the double loop, and both ends of theinsurance wire 40 extend toward the direction of the movingwire segment 33 , so that thering structure 41 can fix the relative position of the double loop on thelasso segment 21 . The arrangement of theinsurance wire 40 can not only achieve the function of fixing the pre-lasso 32, but also can increase the number of theinsurance wires 40 when they are later formed into a fixed knot A with thering structure 41 and the pre-lasso 32. The effect of the size of the fixed knot A, the steps and features of forming the pre-lasso 32 into the fixed knot A will be further described in detail later.

由於該纏繞結322形成於該套索段21的方式並無限定，如圖2本發明所提供之第二較佳實施例中，該繫綁線段31以一參圈纏繞形成該活結的方式於該套索段21上形成該纏繞結322，其中該保險線材40穿越該纏繞結322的該參圈，且該保險線材40之兩端皆朝向該做動線段33之方向延伸，如此該環形結構41便可以固定該參圈於該套索段21上的相對位置。該纏繞結322形成於該套索段21的圈數可以依據所需增加或減少，隨著該纏繞結322纏繞該套索段21的圈數增加，該預套索32於後續形成該固定結A的尺寸也可以隨之增加。There is no limit to the way in which the windingknot 322 is formed on thelasso section 21. In the second preferred embodiment of the present invention as shown in Figure 2, thebinding wire section 31 is wound in a loop to form the slip knot. The windingknot 322 is formed on thelasso section 21 , in which theinsurance wire 40 passes through the loop of the windingknot 322 , and both ends of theinsurance wire 40 extend towards the direction of the movingwire section 33 , so that thering structure 41 can fix the relative position of the reference loop on thelasso section 21. The number of turns of the windingknot 322 formed on thelasso section 21 can be increased or decreased as required. As the number of turns of the windingknot 322 around thelasso section 21 increases, the pre-lasso 32 will subsequently form the fixed knot. The size of A can also be increased accordingly.

如圖3，本發明所提供之第三較佳實施例，該繫綁線段31同樣的以該參圈纏繞形成於該套索段21上形成該纏繞結322，於前述不同之處在於，該保險線材40穿越該參圈中位置於一自由端方向的其中一圈，使得該環形結構41僅扣勾位於自由端方向的該其中一圈，如此，其他二圈可以經由該保險線材40以及該其中一圈的抵靠保留於該套索段21上靠近該外管10的位置。由該環形結構41僅與該其中一圈相互扣勾，相較於第二實施例而言，該環形結構41的大小相對較小，於後續形成該固定結A的尺寸也相對的小於上述之第二實施例，使得本發明可以依據一欲打結的位置(如：傷口的部位或是組織的特性)等需求，經由調整該纏繞結322以及該環形結構41展現多樣的打結型態。As shown in FIG. 3 , in the third preferred embodiment provided by the present invention, the tyingwire segment 31 is also wound around thelasso segment 21 with the loop to form the windingknot 322 . The difference is that the Theinsurance wire 40 passes through one of the circles located in the free end direction, so that theannular structure 41 only hooks the one circle located in the free end direction. In this way, the other two circles can pass through theinsurance wire 40 and the The abutment of one ring remains on thelasso section 21 close to theouter tube 10 . Theannular structure 41 is only interlocked with one of the rings. Compared with the second embodiment, the size of theannular structure 41 is relatively smaller, and the size of the fixed knot A that is subsequently formed is also relatively smaller than the above. The second embodiment makesThe present invention can display various knotting patterns by adjusting the windingknot 322 and theannular structure 41 according to the requirements of a location to be knotted (such as the location of a wound or the characteristics of a tissue).

如圖4，該保險線材40不僅限於與該纏繞結322相互扣勾，該保險線材40亦可以穿越該緊束圈321的形式存在，本實施例中，該保險線材40形成該環形結構41與該緊束圈321相互扣勾，且該環形結構41位置於該緊束圈321與該纏繞結322連接處，其中，該保險線材40之兩端皆朝向該做動線段33之方向延伸，使得該環形結構41可以抵靠該纏繞結322，並將該纏繞結322保留於該套索段21上靠近該外管10的位置。As shown in Figure 4, theinsurance wire 40 is not limited to being interlocked with the windingknot 322. Theinsurance wire 40 can also exist in the form of passing through the tighteningring 321. In this embodiment, theinsurance wire 40 forms theannular structure 41 and The tightening rings 321 are interlocked with each other, and theannular structure 41 is located at the connection between the tighteningring 321 and the windingknot 322 , wherein both ends of theinsurance wire 40 extend toward the direction of the movingline segment 33 , so that Theannular structure 41 can abut the windingknot 322 and retain the windingknot 322 on thelasso section 21 close to theouter tube 10 .

進一步地，該保險線材40也可以形成一死結於該預套索32的至少一部份，該保險線材40所形成的該死結包含有與該預套索相互扣勾的該環形結構41以及一打結結構，如此，可以確保該保險線材40不會相對該預套索32位移。Furthermore, theinsurance wire 40 can also form a dead knot on at least a part of the pre-lasso 32. The dead knot formed by theinsurance wire 40 includes theannular structure 41 interlocking with the pre-lasso and a The knotted structure ensures that theinsurance wire 40 will not be displaced relative to the pre-lasso 32 .

配合參考圖1、圖5至圖7，其為本發明打結組成形成該固定結A之步驟示意圖，包含至少一條打結線材50，該打結線材50穿越該緊束圈321，位置於該緊束圈321內的該打結線材50可以界定為一打結線段51。Referring to Figures 1, 5 to 7, which are schematic diagrams of the steps of forming the fixed knot A according to the knotting composition of the present invention, including at least oneknotting wire 50, theknotting wire 50 passes through the tighteningcircle 321 and is located at the The knottedwire 50 within the tighteningcircle 321 can be defined as a knottedwire segment 51 .

首先，該固定結A欲形成時，拉動位置於該內管20內的該做動線段33，使得該緊束圈321經由該做動線段33收束而逐漸縮小並抵靠至該套索段21前端，此時該打結線段51隨著該緊束圈321的緊束，該打結線段51也一併的抵靠至該套索段21前端或是該套索段21的一外周圍表面。First, when the fixed knot A is to be formed, the movingline segment 33 located in theinner tube 20 is pulled, so that the tighteningring 321 is tightened through the movingline segment 33 and gradually shrinks and abuts against the lasso segment. 21 front end, at this time, the knottedline segment 51 follows the tightening of the tighteningring 321, and the knottedline segment 51 also abuts against the front end of thelasso segment 21 or an outer periphery of thelasso segment 21 surface.

隨著該做動線段33持續拉動，該緊束圈321帶動該內管20內相對外管10做動並移入至該外管10內，使得該套索段21之長度逐漸縮短，此時該纏繞結322以及該保險線材40經由該外管10推移，逐漸於該套索段21上朝向該自由端方向移動。需注意的是，該纏繞結322以及該保險線材40朝向該自由端方向移動時，該做動線段33仍是持續拉動，因此該緊束圈321仍保持緊束，而該保險線材40的配置可以防止該纏繞結322於該套索段21移動時提前鬆脫。As the movingwire segment 33 continues to pull, the tighteningring 321 drives theinner tube 20 to move relative to theouter tube 10 and move into theouter tube 10 , so that the length of thelasso segment 21 is gradually shortened. The windingknot 322 and theinsurance wire 40 are pushed through theouter tube 10 and gradually move on thelasso section 21 toward the free end. It should be noted that when the windingknot 322 and theinsurance wire 40 move toward the free end, theactuating wire segment 33 continues to pull, so the tighteningring 321 remains tight, and the configuration of theinsurance wire 40 This can prevent the windingknot 322 from loosening prematurely when thelasso section 21 moves.

接著，該做動線段33持續拉動，且該外管10持續推移該纏繞結322以及該保險線材40朝向該自由端方向移動，當該纏繞結322以及該保險線材40位置於當該套索段21上該自由端最末端外周圍時，該打結線段51經由緊束抵靠於該外管10該自由端該內管通孔22的開口。進一步地，該保險線材40透過該環形結構41可以將該纏繞結322留置於該內管該自由端最末端位置，可以防止該纏繞結322隨著該做動線段33帶動而掉落至該內管20之內管通孔22中，此特徵可以使得該纏繞結322或是於後續形成的該固定結A不需要限定其大小必需大於該內管20之管口，如此，便可以更加的靈活以及廣泛的使用本案所提供之打結組成。Then, theactuating wire segment 33 continues to pull, and theouter tube 10 continues to push the windingknot 322 and theinsurance wire 40 toward the free end direction. When the windingknot 322 and theinsurance wire 40 are positioned at thelasso segment 21 on the outer periphery of the outermost end of the free end, the knottedline segment 51 is tightly tied against the opening of the inner tube throughhole 22 at the free end of theouter tube 10 . Furthermore, theinsurance wire 40 can leave the windingknot 322 at the end position of the free end of the inner tube through theannular structure 41 to prevent the windingknot 322 from falling into the inner tube as the movingwire segment 33 drives it. In the inner tube throughhole 22 of thetube 20, this feature can make the windingknot 322 or the subsequently formed fixed knot A need not limit its size to be larger than the tube opening of theinner tube 20, so that it can be more flexible. As well as extensive use of the knotting composition provided by this case.

最後，當該套索段21完全的收入至該外管10內時，該纏繞結322以及該保險線材40完全脫離該套索段21，此時該纏繞結322內界定有一緊束空間。同時地，該做動線段33持續拉動，使得該束套圈22拉動該打結線段51反折形成一緊束環結構511深入該緊束空間，該纏繞結322經由該做動線段33持續拉動，使得該預套索32緊束該打結線段51以及該保險線材40形成該固定結A。Finally, when thelasso section 21 is completely retracted into theouter tube 10, the windingknot 322 and theinsurance wire 40 are completely separated from thelasso section 21. At this time, a tightening space is defined in the windingknot 322. At the same time, theactuating line segment 33 continues to pull, so that thebundle ferrule 22 pulls the knottedline segment 51 and folds it to form a tighteningring structure 511 that goes deep into the tightening space, and the windingknot 322 continues to pull through theactuating line segment 33 , so that the pre-lasso 32 tightly binds the knottedline segment 51 and theinsurance wire 40 to form the fixed knot A.

當該套索段21完全的收入至該外管10內時，當該固定結A之尺寸大於該外管10該自由端的一開口，可以避免該固定結A形成時陷入該外管10的該開口，且該外管10也可以產生一抵靠作用，使得該固定結A形成時可以經由該外管10前端抵靠於欲打結的位置，進一步地達到防止該纏繞結322以及該保險線材40在脫離該套索段21的瞬間位移，避免該固定結A形成於不理想的位置。希望新增When thelasso section 21 is completely retracted into theouter tube 10, when the size of the fixed knot A is larger than an opening of the free end of theouter tube 10, it can prevent the fixed knot A from sinking into theouter tube 10 when formed. opening, and theouter tube 10 can also produce a resisting effect, so that when the fixed knot A is formed, the front end of theouter tube 10 can be pressed against the position to be knotted, thereby further preventing the entanglement of theknot 322 and the insurance wire. The instantaneous displacement of 40 when it is separated from thelasso section 21 prevents the fixed knot A from being formed in an undesirable position. Hope to add

本發明所提供之打結組成在該固定結A後，由於包含了該纏繞結322、該保險線材40以及緊束環結構511互相纏繞於其中，使得的彼此間接觸面增加，進一步的增加了該固定結A整體摩擦力，可以更佳的預防該固定結A鬆脫，尤其是應用於一單股線材上。另外的，也可以在該固定結A欲形成時，先將該保險線材40至該預套索32以及該套索段21之間抽離，如此，便可以依據需求縮小該固定結A形成後之尺寸。After the fixed knot A, the knotting composition provided by the present invention includes the windingknot 322, theinsurance wire 40 and the tighteningring structure 511 intertwined with each other, so that the contact surface between each other is increased, further increasing the The overall friction of the fixed knot A can better prevent the fixed knot A from loosening, especially when applied to a single wire. In addition, when the fixed knot A is to be formed, firstTheinsurance wire 40 is pulled away from the pre-lasso 32 and thelasso section 21, so that the size of the fixed knot A can be reduced according to needs.

本發明透過該保險線材固定該預套索，無須設置其他的一固定結構，使得本發明所提供之打結組成可以將整體體積設計至最小，也由於省略了該固定結構，使得管狀的該內管以及該外管可以是一軟質材料所形成，使得該打結組成可以適應於複雜以及狹小的空間中，有助於微創手術的使用與進步。The present invention fixes the pre-lasso through the insurance wire, without the need to provide another fixing structure, so that the knotting composition provided by the present invention can design the overall volume to a minimum, and because the fixing structure is omitted, the tubular inner The tube and the outer tube can be made of a soft material, so that the knotted composition can be adapted to complex and narrow spaces, which is helpful for the use and advancement of minimally invasive surgery.

本發明中，該繫綁線材30、該保險線材40以及該打結線材50並不限為相同類型或尺寸的線材，該繫綁線材30、該保險線材40以及該打結線材50亦不限定為手術縫合線，一使用者可以依據所需選擇該繫綁線材30、該保險線材40以及該打結線材50之大小、該纏繞結322形成於該套索段21的圈數、該保險線材40扣勾於該預套索32的位置以及該打結線材50穿入該緊束圈321的數量，進一步的調整該固定結A的尺寸，使的本發明極具應用性。另外，該繫綁線材30、該保險線材40以及該打結線材50並不限定為三條分開之線材，某些實施例上，該繫綁線材30與該保險線材40可以是相互連接的同一條線材，該繫綁線材30也可以與該打結線材50為相互連接的同一條線材，又或是該保險線材40與該打結線材50為相互連接的同一條線材。In the present invention, the bindingwire 30 , theinsurance wire 40 and theknotting wire 50 are not limited to wires of the same type or size, and thebinding wire 30 , theinsurance wire 40 and theknotting wire 50 are not limited to For surgical sutures, a user can select the size of the tyingwire 30, theinsurance wire 40 and theknotting wire 50, the number of turns of the windingknot 322 formed on thelasso section 21, and the insurance wire according to the needs. The position of the 40 buckle hooked on the pre-lasso 32 and the number of the knottedwires 50 penetrating into the tighteningring 321 can further adjust the size of the fixed knot A, making the present invention highly applicable. In addition, the bindingwire 30 , theinsurance wire 40 and theknotting wire 50 are not limited to three separate wires. In some embodiments, the bindingwire 30 and theinsurance wire 40 may be the same one connected to each other.
