技术领域Technical field
本发明涉及骨科医疗器械技术领域，特别涉及一种基于线缆的骨搬运装置。The present invention relates to the technical field of orthopedic medical devices, and in particular to a cable-based bone transport device.
背景技术Background technique
骨搬运装置是为了实现骨延长(和/或骨搬运)而专用的装置；其工作原理为：针对骨缺损的部位，将骨缺损的近端或远端截骨，并保留骨膜完整性，软组织和血供；之后将骨搬运装置固定于骨骼的两端，并对截断的搬运骨段进行牵拉，以使搬运骨段向缺损处缓慢移动，在此过程中人体机体组织的再生潜能被激活，使截骨间隙生长出新骨，最终达到修复骨缺损，延长骨短缩的目的。The bone transport device is a device specially designed to achieve bone lengthening (and/or bone transport); its working principle is: targeting the bone defect site, osteotomizing the proximal or distal end of the bone defect while retaining the integrity of the periosteum and soft tissue and blood supply; then the bone transport device is fixed on both ends of the bone, and the severed transport bone segment is stretched so that the transport bone segment slowly moves toward the defect. In this process, the regenerative potential of human body tissue is activated. , causing new bone to grow in the osteotomy gap, ultimately achieving the purpose of repairing bone defects and prolonging bone shortening.
现有的骨搬运装置采用环式外固定支架或单边外固定支架，并通过外固定钉或克氏针拉动游离骨的方式来进行牵拉，这种方案组装费时费力，操作繁琐，容易导致搬运骨段在牵拉过程中出现位置偏差，使得最终结合生长的新骨出现弯曲或偏移，且因外固定钉或克氏针是直接穿过皮肤固定于搬运骨段，故在牵拉过程中会破坏皮肤软组织的完整性，甚至可能损伤血管、神经组织，给病人造成痛苦的同时也增加了感染风险。The existing bone handling device uses a ring-type external fixation bracket or a unilateral external fixation bracket, and pulls the free bone through external fixation nails or Kirschner wires. This solution is time-consuming and labor-intensive to assemble, cumbersome to operate, and can easily lead to The position of the transported bone segment deviates during the pulling process, causing the new bone that will eventually grow together to bend or shift. Moreover, because the external fixation nails or Kirschner wires directly pass through the skin and are fixed to the transported bone segment, during the stretching process It will destroy the integrity of the skin and soft tissue, and may even damage blood vessels and nerve tissue, causing pain to the patient and increasing the risk of infection.

In one embodiment of a cable-based bone transporting device proposed by the present invention, the cable-based bone transporting device includes a fixed component, a transporting component, a moving component, an intramedullary component, and an intramedullary component. Nails 820 and cables 160; the handling assembly includes a first screw rod 220 and a second screw rod 230 that are parallel to each other; the number of fixing assemblies is at least 2; the fixing assembly is provided on the handling assembly; the fixing assembly is used to fix the handling assembly on The first bone 110 and the second bone 140 are respectively located at both ends of the transport bone segment 120; the intramedullary nails 820 are sequentially inserted into the intramedullary cavity of the first bone 110, the intramedullary cavity 130 of the transport bone segment, and the intramedullary cavity of the second bone. Cavity 150 (specifically, a transverse fixation rod (not shown) is passed between the intramedullary nail 820 and the first bone 110, so that one end of the intramedullary nail 820 is fixed to the first bone 110; the intramedullary nail 820 is connected to the first bone 110. A transverse fixing rod (not shown) is passed between the two bones 140, so that the other end of the intramedullary nail 820 is fixed to the second bone 140); the moving part is movably connected to the handling assembly; one end of the cable 160 is used for connection When transporting the bone segment 120, the other end of the cable 160 is used to pass through the intramedullary cavity 130 of the transported bone segment, then penetrate into the intramedullary cavity 150 of the second bone, then pass through the bone wall of the second bone 140 and then extend from the limb. And connected to the moving part; the moving part can move along the longitudinal axis of the first screw rod 220 in the direction close to the first bone 110 to drive the cable 160, and then drive the bone segment 120 to be moved close to the first bone 110 along the axis of the intramedullary nail 820. The second bone moves in the direction of 140 degrees.
本发明提出的基于线缆的骨搬运装置首先通过固定组件将第一骨110、第二骨140和搬运组件三者进行固定，从而保持第一骨110和第二骨140的相对位置；然后通过将线缆160的一端连接于搬运骨段120，将线缆160的另一端穿过搬运骨段的髓内腔130后，穿入第二骨的髓内腔150再穿过第二骨140的骨壁后从肢体伸出并连接于移动部件，使用时通过定期驱动移动部件，以带动线缆160(如附图1所示，具体实施中，移动部件以每天向上移动1mm的速度进行移动)，从而带动搬运骨段120向靠近第二骨140的方向移动(如附图1所示，带动搬运骨段120向下移动)，从而使搬运骨段120逐渐靠近第二骨140，以便于激活人体机体组织的再生潜能，在此过程中使得第一骨110和第二骨140之间长出新骨，最终使搬运骨段120与第二骨140接触，使搬运骨段120与第二骨140结合生长在一起；整个使用过程中，通过线缆160来径向拉动搬运骨段120沿髓内钉820向第二骨140靠近，能够避免搬运骨段120在牵拉过程中出现位置偏差，且线缆160通过一个小孔即可穿出肢体，避免在搬运骨段对皮肤软组织的破坏，从而大大减少病人的痛苦和感染风险。The cable-based bone handling device proposed by the present invention first fixes the first bone 110, the second bone 140 and the handling assembly through the fixing assembly, thereby maintaining the relative position of the first bone 110 and the second bone 140; and then through One end of the cable 160 is connected to the transport bone segment 120, and the other end of the cable 160 is passed through the intramedullary cavity 130 of the transport bone segment, then penetrates into the intramedullary cavity 150 of the second bone and then passes through the second bone 140.
