In FIG. 1, the upper side shows a state in which the suture thread 3 is locked to the suture thread locking member 4, and the lower side shows a state before the suture thread 3 is locked to the suture thread locking member 4. Show.

縫合針2は、例えば、略円弧状に形成された周知の縫合針が適用可能であり、縫合針本体の一端部に、縫合糸3を通す通し孔が形成されている。
縫合糸3は、周知の縫合糸が適用可能であり、縫合針2と接続される側は一本に形成されるとともに、縫合糸係止部材4と接続される側は縫合糸係止部材4の孔に通されて環状に形成されている。
As the suturing needle 2, for example, a well-known suturing needle formed in a substantially arc shape is applicable, and a through hole through which the suturing thread 3 is passed is formed at one end of the suturing needle body.
A well-known suture can be applied to the suture 3, and the side connected to the suture needle 2 is formed as one, and the side connected to the suture lock member 4 is the suture lock member 4. And is formed in an annular shape.

縫合糸係止部材4は、図2に示すように、第1壁部42Aと、第2壁部42Bと、第1壁部42Aの裏面に形成された第1補強壁部46Aと、第2壁部42Bの裏面に形成された補強壁部46Bと、縫合糸3の終了端側を係止する係止部44とを備え、第1壁部42Aと第2壁部42Bは接続部41を介して接続されている。   As shown in FIG. 2, the suture locking member 4 includes a first wall portion 42A, a second wall portion 42B, a first reinforcing wall portion 46A formed on the back surface of the first wall portion 42A, and a second wall portion 42A. A reinforcing wall portion 46B formed on the back surface of the wall portion 42B and a locking portion 44 for locking the end end side of the suture thread 3 are provided, and the first wall portion 42A and the second wall portion 42B connect the connecting portion 41. Connected through.

第1壁部42A及び第2壁部42Bは、例えば、図1、2に示すように、それぞれ円形膨出部材により構成され、それぞれ膨出する側を対向配置するとともに、第1壁部42A及び第2壁部42Bの中央部は、長手方向の中央部が円弧状に凹む略円柱状の接続部41により接続されており、この実施形態において、第1壁部42A、第2壁部42B及び接続部41は、シリコン等の弾性材料により一体に形成されている。   For example, as shown in FIGS. 1 and 2, the first wall portion 42 </ b> A and the second wall portion 42 </ b> B are each constituted by a circular bulging member, and the bulging sides are arranged opposite to each other, and the first wall portion 42 </ b> A and The central part of the second wall part 42B is connected by a substantially cylindrical connecting part 41 whose central part in the longitudinal direction is recessed in an arc shape. In this embodiment, the first wall part 42A, the second wall part 42B, The connecting portion 41 is integrally formed of an elastic material such as silicon.

係止部44は、第1壁部42Aと第2壁部42Bの間に形成され、引張力が作用した状態の縫合糸3に押圧されることにより、第1壁部42A第2壁部42Bが弾性変形して第1壁部と第2壁部の間に形成される収容部により構成されている。   The locking portion 44 is formed between the first wall portion 42A and the second wall portion 42B, and is pressed against the suture thread 3 in a state where a tensile force is applied, whereby the first wall portion 42A and the second wall portion 42B. Is formed by an accommodating portion formed between the first wall portion and the second wall portion by elastic deformation.

The suture thread 3 that is formed over and wound around the connection portion 41 is always accommodated in the accommodating portion between the first wall portion 42A and the second wall portion 42B.

ここで、接続部41に縫合糸3を巻き付ける、又は巻回するとは、接続部41に縫合糸3を複数回巻き付ける場合のほか、縫合糸3を接続部41の周囲に一周未満の範囲で接触させる場合を含み、縫合糸3が接続部41に密着した状態で巻き付けられることを要しない。   Here, the suture thread 3 is wound around or wound around the connecting portion 41, in addition to the case where the suture thread 3 is wound around the connecting portion 41 a plurality of times, and the suture thread 3 is brought into contact with the periphery of the connecting portion 41 within a range of less than one round. It is not necessary for the suture thread 3 to be wound in a state of being in close contact with the connection portion 41.

第1補強壁部46A、補強壁部46Bは、例えば、チタン等、生体に拒絶反応を生じにくい材料からなり、第1壁部42A、第2壁部42Bの背面と相補的な円形皿状に形成され、第1壁部42A、第2壁部42Bの背面に配置されて、第1壁部42A及び第2壁部42Bが互いに離間しすぎるのを抑制するようになっている。   The first reinforcing wall portion 46A and the reinforcing wall portion 46B are made of, for example, a material that hardly causes a rejection reaction in the living body, such as titanium, and have a circular dish shape complementary to the back surfaces of the first wall portion 42A and the second wall portion 42B. The first wall portion 42A and the second wall portion 42B are formed and arranged on the back surfaces of the first wall portion 42A and the second wall portion 42B so as to prevent the first wall portion 42A and the second wall portion 42B from being separated too much from each other.

また、縫合糸係止部材4には、第1壁部42A、第1補強壁部46A、接続部41、第2壁部42B、補強壁部46Bを貫通する貫通孔43が形成されていて、貫通孔43には縫合糸3を通すことができるようになっている。   Further, the suture locking member 4 is formed with a through-hole 43 penetrating the first wall portion 42A, the first reinforcing wall portion 46A, the connecting portion 41, the second wall portion 42B, and the reinforcing wall portion 46B.

(1) First, as shown in FIG. 3A, when a biological tissue T1 and a corresponding biological tissue T2 are sutured, for example, a suture needle along the arrow J from the biological tissue T2 to the biological tissue T1. Move 2
As a result, the living tissue T2 and the living tissue T1 are connected by the suture thread 3.
(2) Next, as shown in FIG. 3B, the suture needle 2 is moved along the arrow J and the suture thread 3 is pulled to close the gap between the living tissue T2 and the living tissue T1.
(3) Next, as shown in FIG. 3 (C), the suture needle 2 is moved in the direction of arrow J so that the suture needle 2 passes through the inside of the annular portion of the suture thread 3 and the predetermined range of the suture thread 3 Is pulled to apply a tensile force to make the suture 3 a linear rigid body, and is pressed between the first wall portion 42A and the second wall portion 42B of the suture locking member 4 to lock the suture thread. The suture thread 3 is accommodated in the locking portion 44 of the member 4.
(4) Next, as shown in FIG. 3D, the suture needle 2 is pulled in the direction of the arrow J, and the suture locking member 4 is fixed to the living tissue T2. Next, the suture needle 2 is moved in the direction of the arrow J1, and the suture thread 3 is wound around the locking portion 41 of the suture needle locking member 41, for example, a plurality of times.
The suture thread 3 accommodated in the locking portion 44 is sandwiched between the first wall portion 42A and the second wall portion 42B and held by the elastic force of the first wall portion 42A and the second wall portion 42B. The end side of the thread 3 is locked to the suture locking member 4.
