る。[0004] In order to collect the tendon for transplantation, a few cm incision is made on the tibia 11 side (near part a in FIG. 4) in order to reduce the skin notch after the operation, and then guided under the subcutaneous area in the chain line area in FIG. The plate is inserted, and the plate is fixed to the tibia 11 with a K-wire (Kirschner wire). After that, the patella tendon 10 in part a is cut off from the surroundings, and a part of the tibia 11 is cut off with a chisel and released. Next, a dual little blade cutter (not shown) is inserted subcutaneously from the incision of the part a, and the cutter is fed in the direction of arrow A in FIG. 4 to cut off both sides of the collection area of the patella tendon 10. Further, the cutter is cut through the outside of the skin at the part b in FIG. 4, and a chisel is inserted from the skin incision formed therein to cut the part b of the patella 17.

タで腱や骨を傷付ける。従って、膝蓋骨側骨片の切り取
りも脛骨側と同様に鑿で行わざるを得なかった。The conventional bone plug cutter is merely for cutting the bone and cannot be used for collecting a tendon for transplantation. When the cutter is inserted subcutaneously from the skin incision on the side of the femur to cut the patella, tendons and bones are damaged by the cutter. Therefore, cutting of the patella-side bone fragments had to be performed with a chisel, similarly to the tibia-side.
【０００９】ところが、鑿を使うと、作業性の悪さによ

も不可欠になる。[0009] However, the use of a chisel causes problems such as a long collection time due to poor workability, a problem that the incision does not become clean, and that the patella tendon and the patella are easily damaged. In addition, in this method, it is necessary to cut the tendon from the tibia side and then cut the patella from the opposite side, so that the incision between the patella tendon and the patella does not connect well, and trimming after collection is also indispensable.
【００１０】さらに、切り取り不良により、創部周辺の
知覚鈍麻、膝蓋骨側採骨部や膝蓋腱自体の圧痛、疼痛な
どの後遺症も生じ易くなる。[0010] In addition, due to poor cutting, sequelae such as hypoesthesia around the wound, tenderness and pain of the patella-side bone-collecting portion and the patella tendon tend to occur.

題としている。Therefore, the present invention provides a method for collecting tendons for transplantation,
An object of the present invention is to make it possible to cut a patella-side bone fragment with a bone plug cutter without damaging the patella or the patella.

る。In order to solve the above-mentioned problems, in a bone plug cutter according to the present invention, an object to be cut (bone fragments and tendons cut from a living body) is passed through the outer periphery of a cylindrical main body. Windows were provided to make it possible.
【００１３】このボーンプラグカッタは、先に述べた方

引き出す。A pull cord is attached to the loose tibia-side bone fragment, and the tibia-side bone fragment and the detached patella tendon connected to the tibia-side bone fragment are led into the main body from the distal end opening and pulled out from the window hole.
【００１５】こうすると、ボーンプラグカッタを脛骨側

脛骨側皮切部から外部に抜き取って採取が完了する。[0015] In this case, the bone plug cutter can be inserted subcutaneously from the skin incision on the tibia to the femur. When the tip of the bone plug cutter inserted under the skin reaches the position of the patella, the pulling cord is pulled to drive the cutting machine, and a part of the patella (portion b in FIG. 4) is scooped from below with the bone plug cutter that performs a rolling motion. In this way, the cutting is advanced while being taken into the main body, and after the cutting is completed, the tendon for transplantation is pulled out from the tibial skin incision to complete the collection.

膝蓋骨側採骨部や膝蓋腱の圧痛、疼痛などを消失させ或
いは軽減することができる。[Function] Unlike a chisel, a bone plug cutter does not damage surrounding bones and tissues more than necessary. According to the present invention, since the bone plug attached to one end of the tendon for transplantation can be cut off by the bone plug cutter, the desensitization around the wound after transplantation can be achieved.
The tenderness and pain of the patella-side bone extraction part and the patella tendon can be eliminated or reduced.
【００１７】また、周囲から切り離した腱を本体に引き

り口の移行がスムーズに行われ、骨片の切り口の乱れも
生じない。従って、切断後の骨片のトリミングも不要に
なる。Further, when the tendon cut off from the surroundings is passed through the main body and cutting is advanced from the tibia side, the cut is smoothly transferred from the tendon to the patella, and the cut of the bone fragment is not disturbed. Therefore, trimming of the bone fragment after cutting is not required.
【００１８】さらに、鑿による切り取りと違って、切断
が楽に迅速に行えるので、手術時間の短縮にもつなが
る。Furthermore, unlike cutting with a chisel, cutting can be performed easily and quickly, which leads to a reduction in operation time.

As an element that characterizes the present invention, a window hole 7 is provided on the outer periphery of the main body 2 so that a transplantable tendon cut out of a patient can be taken out. If the window hole 7 is a square hole, the strength of the main body is reduced due to the concentration of stress at the corner of the hole. Therefore, a rounded hole is preferable. Further, a slightly longer hole is preferable because the tendon can be easily extracted from the inside of the main body. As shown in FIG. 7, one end of the patella tendon 10 (the part where both sides are cut off from the periphery) with the tibial bone fragment 11 a is pulled out from the window hole 7 (the pulling-out is performed by using a drawstring attached to one end). 8), and the cutter 1 is inserted subcutaneously from the tibia skin incision. Then, the tendon is stretched straight with a drawstring, and the patella 17 is cut off with the cutter 1.
