Description

本発明は、骨折治療用装置に関する。   The present invention relates to a fracture treatment device.

腕、脚等が骨折すると筋肉等の収縮力により腕等が収縮する。この収縮を伴う骨折を治療するには、軟部組織を切開し、ネールを骨の一端から他端へと骨髄内に挿入し、牽引装置又は人手により骨折した脚等を牽引して骨折前の状態まで引き伸ばしたうえで、骨の側面からネールに向かってスクリューを差し込み、スクリューをネールの孔にねじ込むことにより骨折線の両側の骨をネールに固定する。その後、切開部を縫合し、骨折部の組織の再生を待つ。   When an arm, leg or the like is broken, the arm or the like contracts due to the contraction force of the muscle or the like. To treat a fracture with this contraction, the soft tissue is incised, a nail is inserted into the bone marrow from one end of the bone to the other, and the fractured leg or the like is pulled by a pulling device or a human hand before the fracture. The bones on both sides of the fracture line are fixed to the nail by inserting a screw from the side of the bone toward the nail and screwing the screw into the hole of the nail. Thereafter, the incision is sutured and waiting for regeneration of the tissue at the fracture.

ところが、従来の骨折治療方法によれば、骨折した骨にネールを挿入した後牽引する場合に、骨折部が成人の脚のように比較的大きい部位であれば既存の牽引装置により牽引することができるが、骨折部位が脚よりも比較的小さい腕、小児の脚、小動物の脚等であるような場合は牽引装置を使用するのが困難である。従来そのような場合は人手で患者の腕、脚等を引っ張りながらネールへの固定を行わざるを得ず、手術が煩雑化し、また、ネールと骨との正確な位置合わせが困難になる場合もある。   However, according to a conventional fracture treatment method, when a nail is inserted into a fractured bone and then towed, if the fractured part is a relatively large part such as an adult leg, it can be pulled by an existing traction device. However, it is difficult to use the traction device when the fracture site is a relatively small arm, leg of a child, leg of a small animal, or the like. Conventionally, in such a case, it is necessary to manually fix the nail while pulling the patient's arm, leg, etc., the operation becomes complicated, and accurate alignment between the nail and the bone may be difficult. is there.

また、骨折の治療にあたり骨には刺入線材、スクリュー等をネールの孔に向かって通す必要があるが、その際術者はネールの孔を視認することができないので、穿孔が不正確になりやすく、手術が煩雑化する。   In addition, when treating fractures, it is necessary to pass a piercing wire, screw, etc. through the bone toward the nail hole, but the operator cannot see the hole in the nail at that time, so the perforation becomes inaccurate.

A head 18 a at the rear end of the feed screw rod 18 protrudes from the rear wall of the jig 4. A nut 21 is screwed into an intermediate portion of the feed screw rod 18, and a coupling screw 22 that penetrates the left and right slide walls 5 b of the traction slider 5 is screwed into the nut 21. Thereby, when the feed screw rod 18 is rotated, the nut 21 is screwed back and forth in the front-rear direction, and the traction slider 5 slides on the jig 4 together with the nut 21 in the front-rear direction.

牽引スライダ5の前端の枠部5aには治具4のガイド孔3aに連通する連通孔23が形成され、この連通孔23内に図7に示す第一の刺入線材6が挿入される。第一の刺入線材6は具体的にはキルシュナー鋼線である。第一の刺入線材6は連通孔23に直に挿入することも可能であるが、望ましくは図7に示す牽引スリーブ17を介して挿入される。この第一の刺入線材6の先端には図示しないがドリル刃が形成されている。図2に示すように、牽引スリーブ17が牽引スライダ5の連通孔23に挿入され骨折線を挟む一方の骨部Aに突き立てられ、牽引スリーブ17をガイドにして第一の刺入線材6が骨部Aに突き立てられる。   A communication hole 23 communicating with the guide hole 3 a of the jig 4 is formed in the frame portion 5 a at the front end of the traction slider 5, and the first insertion wire 6 shown in FIG. 7 is inserted into the communication hole 23. The first insertion wire 6 is specifically Kirschner steel wire. Although it is possible to insert the first insertion wire 6 directly into the communication hole 23, it is preferably inserted through the traction sleeve 17 shown in FIG. Although not shown, a drill blade is formed at the tip of the first insertion wire 6. As shown in FIG. 2, the traction sleeve 17 is inserted into the communication hole 23 of the traction slider 5 and protruded to one bone portion A sandwiching the fracture line, and the first insertion wire 6 is formed using the traction sleeve 17 as a guide. The bone part A is thrust.

図2に示すように、治具4の前部グループのガイド孔3bには、図8に示す第二の刺入線材7が挿入される。第二の刺入線材7は具体的にはキルシュナー鋼線である。この第二の刺入線材7の先端にも図示しないドリル刃が形成される。第二の刺入線材7はガイド孔3bに直に挿入することも可能であるが、望ましくは図8に示す内外のガイドスリーブ24a,24bを介して挿入される。図2に示すように、外ガイドスリーブ24bが治具4のガイド孔3bに挿入され骨折線を挟む他方の骨部Bに突き立てられ、内ガイドスリーブ24aが外ガイドスリーブ24b内に挿入され、図示しないドリルで第二の刺入線材7が内ガイドスリーブ24aをガイドにして骨部Bに突き立てられる。   As shown in FIG. 2, the second insertion wire 7 shown in FIG. 8 is inserted into the guide hole 3 b of the front group of the jig 4. The second insertion wire 7 is specifically a Kirschner steel wire. A drill blade (not shown) is also formed at the tip of the second insertion wire 7. The second insertion wire 7 can be inserted directly into the guide hole 3b, but is preferably inserted through the inner and outer guide sleeves 24a and 24b shown in FIG. As shown in FIG. 2, the outer guide sleeve 24 b is inserted into the guide hole 3 b of the jig 4 and protrudes into the other bone B sandwiching the fracture line, and the inner guide sleeve 24 a is inserted into the outer guide sleeve 24 b. The second insertion wire 7 is thrust into the bone part B with the inner guide sleeve 24a as a guide by a drill (not shown).

また、図2に示すように、治具4の後部グループのガイド孔3aには、第三の刺入線材25及び内外のガイドスリーブ26a,26bが必要に応じて挿入される。この第三の刺入線材25及び内外のガイドスリーブ26a,26bは上記第二の刺入線材7及び内外のガイドスリーブ24a,24bと同様な構成である。   As shown in FIG. 2, a third insertion wire 25 and inner and outer guide sleeves 26a and 26b are inserted into the guide hole 3a of the rear group of the jig 4 as necessary. The third insertion wire 25 and the inner and outer guide sleeves 26a and 26b have the same configuration as the second insertion wire 7 and the inner and outer guide sleeves 24a and 24b.

上記第二及び第三の刺入線材7,25はネール2のネジ孔1を通るように骨部B,Aを横断するが、後述する手術の途中で抜き取られ、その跡に図19に示すようにスクリュー8が挿入され、このスクリュー8がネール2のネジ孔1に螺合する。   The second and third insertion wires 7 and 25 cross the bones B and A so as to pass through the screw holes 1 of the nail 2, but are extracted during the later-described operation, and the trace is shown in FIG. Thus, the screw 8 is inserted, and the screw 8 is screwed into the screw hole 1 of the nail 2.

次に、上記構成の骨折治療用装置の作用について説明する。   Next, an operation of the fracture treatment device having the above-described configuration will be described.

(1)図9に示すように、小動物の大腿骨の骨折を治療するものとし、この大腿骨に適合するネール2を選定し、このネール2をネールホルダ9に取り付ける。   (1) As shown in FIG. 9, a fracture of a femur of a small animal is to be treated, and a nail 2 that matches the femur is selected, and the nail 2 is attached to the nail holder 9.

また、小動物を側臥位にし、軟組織を切開し、骨折線を挟む近位側骨部Aに近位端から図示しない髄空リーマによってリーミングし、同じく遠位側骨部Bに近位端から髄空リーマによってリーミングし、両骨部A,Bの骨軸上に下孔を開ける。     Further, the small animal is placed in the lateral position, the soft tissue is incised, the proximal bone part A sandwiching the fracture line is reamed from the proximal end by a medullary reamer (not shown), and the distal bone part B is also medullary from the proximal end Reaming is performed with an empty reamer, and a pilot hole is opened on the bone axes of both bone parts A and B.

術者はネールホルダ9の取っ手9eを握り、図9に示すようにネール2を下孔に挿入する。ネール2は大腿骨の遠位側骨部Bの底に着いて停止する。     The operator grasps the handle 9e of the nail holder 9 and inserts the nail 2 into the prepared hole as shown in FIG. The nail 2 arrives at the bottom of the distal bone B of the femur and stops.

(2)図10に示すように、ネールホルダ9を介してネール2を治具4に連結する。これにより、治具4はネール2に平行に伸び、ネール2のネジ孔1が治具4のガイド孔3a,3bに正対する。   (2) As shown in FIG. 10, the nail 2 is connected to the jig 4 via the nail holder 9. As a result, the jig 4 extends parallel to the nail 2, and the screw hole 1 of the nail 2 faces the guide holes 3 a and 3 b of the jig 4.

(3)送りねじ棒18を回し、図11に示すように、牽引スライダ5を治具4上で前進位置へと移動させておく。牽引用の刺入線材として第一の刺入線材6を近位側の骨部Aの転子部に突き立てる。   (3) The feed screw rod 18 is rotated, and the traction slider 5 is moved to the advance position on the jig 4 as shown in FIG. The first piercing wire 6 is pushed as a trochanter portion of the proximal bone portion A as a piercing wire for traction.

この作業は次のようにして行う。まず、牽引スライダ5の連通孔23に牽引スリーブ17を挿入し、牽引スリーブ17の先端を骨部Aに突き立てる。次に、第一の刺入線材6を牽引スリーブ17内に挿入し、図示しないドリルで第一の刺入線材6をチャッキングして回転させ、骨部A内に挿入する。これにより、近位側の骨部Aが牽引スライダ5に連結される。   This work is performed as follows. First, the traction sleeve 17 is inserted into the communication hole 23 of the traction slider 5, and the tip of the traction sleeve 17 is pushed to the bone part A. Next, the first insertion wire 6 is inserted into the pulling sleeve 17, and the first insertion wire 6 is chucked and rotated with a drill (not shown) and inserted into the bone part A. As a result, the proximal bone portion A is connected to the traction slider 5.

(4)図12に示すように、第二の刺入線材7を治具4の前部グループのガイド孔3bから遠位側骨部Bに突き立ててネール2のネジ孔1に挿入する。   (4) As shown in FIG. 12, the second insertion wire 7 is inserted into the screw hole 1 of the nail 2 while protruding from the guide hole 3 b of the front group of the jig 4 to the distal bone part B.

この作業は次のようにして行う。まず、治具4のガイド孔3bに外ガイドスリーブ24bを挿入し、外ガイドスリーブ24bの先端を骨部Bに突き立てた後、内ガイドスリーブ24aを外ガイドスリーブ24b内に挿入する。内ガイドスリーブ24a内に第二の刺入線材7を挿入し図示しないドリルで回転させて骨部B内に挿入する。これにより、遠位側の骨部Bが治具4に連結され仮固定される。   This work is performed as follows. First, the outer guide sleeve 24 b is inserted into the guide hole 3 b of the jig 4, the tip of the outer guide sleeve 24 b is protruded to the bone part B, and then the inner guide sleeve 24 a is inserted into the outer guide sleeve 24 b. The second insertion wire 7 is inserted into the inner guide sleeve 24a, rotated by a drill (not shown), and inserted into the bone B. Thereby, the bone part B on the distal side is connected to the jig 4 and temporarily fixed.

この骨折治療用の治具4はネール2に連結した際にネール2のネジ孔1に夫々正対する複数個のガイド孔3a,3bを有することから、骨髄内に通することにより外部から見えなくなったネール2のネジ孔1に対し刺入線材7を簡易かつ正確に挿入することができる。   Since this fracture treatment jig 4 has a plurality of guide holes 3a and 3b that respectively face the screw holes 1 of the nail 2 when connected to the nail 2, it is invisible from the outside by passing through the bone marrow. The insertion wire 7 can be easily and accurately inserted into the screw hole 1 of the nail 2.

(5)図13に示すように、送りねじ棒18を回して牽引スライダ5を治具4上で後方にスライドさせる。送りねじ棒18はその頭部18aに図示しないラチェットハンドル等の工具を係止することにより容易に回転させることができる。これにより第二の刺入線材7に対し第一の刺入線材6が後方に牽引され、骨折線を挟んで遠位の骨部Bに対し近位の骨部Aが骨折前の元の位置まで引き離される。   (5) As shown in FIG. 13, the feed screw rod 18 is rotated to slide the traction slider 5 backward on the jig 4. The feed screw rod 18 can be easily rotated by locking a tool such as a ratchet handle (not shown) to the head portion 18a. As a result, the first insertion wire 6 is pulled backward with respect to the second insertion wire 7, and the proximal bone part A with respect to the distal bone part B across the fracture line is the original position before the fracture. Pulled away.

(6)図14に示すように、近位の骨部Aに第一のスクリュー8aを挿入し、ネール2のネジ孔1と螺合させる。   (6) As shown in FIG. 14, the first screw 8 a is inserted into the proximal bone part A and screwed into the screw hole 1 of the nail 2.

この作業は(4)の場合とほぼ同様に行う。すなわち、治具4の後部グループのガイド孔3aに(4)の場合と同様な内外のガイドスリーブ24a,24bを挿入し、外ガイドスリーブ24bの先端を骨部Aに突き立てる。内ガイドスリーブ24a内に図示しないドリル刃を挿入して下孔をあけ内ガイドスリーブ24aを抜き取った跡に図示しないデプスゲージを挿入し、必要なスクリュー8の長さを測定する。デプスゲージを外ガイドスリーブ24b外に抜き取った後、再び内ガイドスリーブ24aを外ガイドスリーブ24b内に挿入し、図示しないタップにより骨部Aにタッピングを行う。その後、内ガイドスリーブ24aを外ガイドスリーブ24bから抜き取って外ガイドスリーブ24bを案内にして図示しないドライバで第一のスクリュー8aを骨部Aに挿入し、ネール2のネジ孔1と螺合させる。最後に外ガイドスリーブ24bをガイド孔3aから抜き取る。この第一のスクリュー8aにより近位側の骨部Aがネール2に本固定される。   This operation is performed in substantially the same manner as in the case of (4). That is, the inner and outer guide sleeves 24 a and 24 b similar to the case of (4) are inserted into the guide hole 3 a of the rear group of the jig 4, and the distal end of the outer guide sleeve 24 b is pushed to the bone part A. A drill blade (not shown) is inserted into the inner guide sleeve 24a to open a pilot hole, and a depth gauge (not shown) is inserted into the trace of the inner guide sleeve 24a being extracted, and the required length of the screw 8 is measured. After the depth gauge is pulled out of the outer guide sleeve 24b, the inner guide sleeve 24a is inserted into the outer guide sleeve 24b again, and tapping is performed on the bone portion A by a tap (not shown). Thereafter, the inner guide sleeve 24a is extracted from the outer guide sleeve 24b, and the first guide screw 8a is inserted into the bone part A with a driver (not shown) using the outer guide sleeve 24b as a guide, and is screwed into the screw hole 1 of the nail 2. Finally, the outer guide sleeve 24b is extracted from the guide hole 3a. The bone part A on the proximal side is permanently fixed to the nail 2 by the first screw 8a.

(7)図15に示すように、(6)と同様な作業を行って、第二のスクリュー8bを遠位側の骨部Bに挿入し、ネール2のネジ孔1と螺合させる。この第二のスクリュー8bにより遠位側の骨部Bがネール2に本固定される。   (7) As shown in FIG. 15, the same operation as in (6) is performed, and the second screw 8 b is inserted into the bone B on the distal side and screwed into the screw hole 1 of the nail 2. The bone B on the distal side is permanently fixed to the nail 2 by the second screw 8b.

(8)図16に示すように、(4)と同様な作業を行って、第三の刺入線材25を治具4の後部グループの他のガイド孔3aから近位側の骨部Aに突き立ててネール2のネジ孔1に挿入する。これにより、近位側の骨部Aが治具4に連結され仮固定される。   (8) As shown in FIG. 16, the same operation as in (4) is performed, and the third insertion wire 25 is moved from the other guide hole 3a of the rear group of the jig 4 to the bone A on the proximal side. Push it up and insert it into the screw hole 1 of the nail 2. Thereby, the bone part A on the proximal side is connected to the jig 4 and temporarily fixed.

(9)図17に示すように、(6)と同様な作業を行って、第三のスクリュー8cを遠位側の骨部Bに挿入し、ネール2のネジ孔1と螺合させる。遠位側の骨部Bはこの第三のスクリュー8cが(7)の第二のスクリュー8bに付加されることによってより強固にネール2に本固定される。この第三のスクリュー8cにより遠位側の骨部Bをネール2に固定する際、(8)で第三の刺入線材25にネール2が仮固定されているので、第三のスクリュー8cはネール2のネジ孔1に正確に螺合する。   (9) As shown in FIG. 17, the same operation as in (6) is performed, and the third screw 8 c is inserted into the bone B on the distal side and screwed into the screw hole 1 of the nail 2. The bone B on the distal side is firmly fixed to the nail 2 more firmly by adding the third screw 8c to the second screw 8b of (7). When the bone B on the distal side is fixed to the nail 2 by the third screw 8c, the nail 2 is temporarily fixed to the third insertion wire 25 in (8). It is screwed into the screw hole 1 of the nail 2 accurately.

(10)図18に示すように、(6)と同様な作業を行って、第四のスクリュー8dを近位側の骨部Aに挿入し、ネール2のネジ孔1と螺合させる。近位側の骨部Aはこの第四のスクリュー8dが(6)の第一のスクリュー8aに付加されることによってより強固にネール2に本固定される。   (10) As shown in FIG. 18, the same operation as in (6) is performed, and the fourth screw 8d is inserted into the proximal bone part A and screwed into the screw hole 1 of the nail 2. The proximal bone portion A is permanently fixed to the nail 2 by adding the fourth screw 8d to the first screw 8a of (6).

(11)図19に示すように、治具4及びネールホルダ9をネール2から取り外した後、ネール2の結合孔10をエンドキャップ27で塞ぐ。また、砕けた骨片を骨折線間に挿入し、所望の方法により固定する。   (11) As shown in FIG. 19, after removing the jig 4 and the nail holder 9 from the nail 2, the coupling hole 10 of the nail 2 is closed with an end cap 27. Moreover, the broken bone fragment is inserted between fracture lines and fixed by a desired method.

その後、軟組織を縫合し、骨折部の再生を待つ。骨折部が再生すると、必要に応じて再び軟組織を切開し、ネール2を大腿骨から抜き取る。   Thereafter, the soft tissue is sutured and the regeneration of the fracture is awaited. When the fracture portion is regenerated, the soft tissue is incised again as necessary, and the nail 2 is extracted from the femur.

なお、本発明は上記実施の形態に限定されるものではなく、例えば上記実施の形態では小動物の大腿骨の骨折治療について説明したが上腕骨、脛骨等他部位の骨折、人間の骨折の治療についても適用可能である。また、手術の手順も適宜変更可能である。また、牽引の際に他方の骨部に挿入する第二の刺入線材を省略することも可能である。すなわち、第一の刺入線材を介して一方の骨部を牽引スライダにより牽引すれば、他方の骨部はネールの先端に当たって止まるので、一方の骨部は他方の骨部に対し引き離されることになる。   Note that the present invention is not limited to the above embodiment. For example, in the above embodiment, the fracture treatment of the femur of a small animal has been described. However, the fracture of other parts such as the humerus and tibia, and the treatment of human fracture Is also applicable. In addition, the procedure of surgery can be changed as appropriate. It is also possible to omit the second insertion wire inserted into the other bone part during towing. That is, if one bone part is pulled by the traction slider via the first insertion wire, the other bone part hits the tip of the nail and stops, so that one bone part is pulled away from the other bone part.
