Description
本發明是有關於一種仿生固定裝置，且特別是有關於一種具有撓性部的仿生固定裝置。 This invention relates to a biomimetic fixation device and, more particularly, to a biomimetic fixation device having a flexible portion.
隨著科技與醫學的進步，係採用例如是骨釘等植入物對人體內的生物組織進行固定，以作為意外傷害或自然老化之修復等醫療用途。 With advances in technology and medicine, implants such as bone nails are used to immobilize biological tissues in the human body for medical purposes such as accidental injury or repair of natural aging.
然而，習知的植入物之彈性模數(Modulus of Elasticity)(約100Gpa)遠大於人體生物組織之彈性模數(小於1Gpa)，當承受之外力過大時容易使生物體產生組織凹陷、壞死、磨損等問題，且植入物也可能因而發生鬆脫。一般來說，傳統的做法係將植入物進行特殊燒結或表面塗佈製程，再以雷射對植入物的表面進行處理，以加強骨整合。但此方式對於改善植入物之應力遮蔽效應有限，加上植入物本身體積較小，更增加了在製程上的困難程度。 However, the Modulus of Elasticity (about 100 GPa) of the conventional implant is much larger than the elastic modulus of the human biological tissue (less than 1 Gpa), and when the external force is too large, it is easy to cause the tissue to sag and necrosis. Problems such as wear and tear, and the implant may also be loosened. In general, the traditional practice is to perform a special sintering or surface coating process on the implant and then treat the surface of the implant with a laser to enhance osseointegration. However, this method has limited stress shielding effect for improving the implant, and the implant itself is small in size, which increases the difficulty in the process.
本發明係有關於一種具有撓性部的仿生固定裝置，利用積層製造製程技術在植入物之表面形成至少一溝槽，透過溝槽結構能有效降低植入物的彈性模數，避免因承受之外力過大使生物體產生組織凹陷、壞死、磨損，或植入物發生鬆脫的情況。 The invention relates to a biomimetic fixing device having a flexible portion, and at least one groove is formed on the surface of the implant by using a lamination manufacturing process technology, and the transmissive groove structure can effectively reduce the elastic modulus of the implant and avoid the bearing Excessive external force causes the organism to produce tissue depression, necrosis, wear, or loosening of the implant.
根據本發明，提出一種仿生固定裝置，包括一撓性部。撓性部包括至少一溝槽，溝槽位於撓性部之表面，且具有一第一端與一第二端。第一端與第二端之間具有一間距。溝槽係分散施加於仿生固定裝置的受力。 According to the present invention, a biomimetic fixture is provided that includes a flexure. The flexible portion includes at least one groove on the surface of the flexible portion and having a first end and a second end. There is a spacing between the first end and the second end. The grooves are distributed to the force applied to the bionic fixture.

以下係參照所附圖式詳細敘述本創作之實施例。圖式中相同的標號係用以標示相同或類似之部分。需注意的是，圖式係已簡化以利清楚說明實施例之內容，圖式上的尺寸比例並非按照實際產品等比例繪製，因此並非作為限縮本發明保護範圍之用。 Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals are used to designate the same or similar parts. It is to be noted that the drawings have been simplified to clearly illustrate the contents of the embodiments, and the dimensional ratios in the drawings are not drawn to the scale of the actual products, and thus are not intended to limit the scope of the present invention.

There is a spacing between the first end and the second end, that is, the first end and the second end are not connected to each other, and the groove is not formed as a closed area. In an embodiment of the invention, the grooves may be used to distribute the forces applied to the bionic fixture.
以下係以第一至第七實施例，並配合圖式第1A~7圖說明本發明之仿生固定裝置。在這些實施例中，將透過立體示意圖，或仿生固定裝置在不同平面上，其溝槽之軌跡進行說明。 Hereinafter, the bionic fixing device of the present invention will be described with reference to the first to seventh embodiments, together with the drawings 1A to 7 of the drawings. In these embodiments, the trajectory of the groove will be described by a three-dimensional diagram, or a bionic fixture on different planes.
第1A圖繪示本發明第一實施例之仿生固定裝置1的示意圖。仿生固定裝置1包括一撓性部10，撓性部10包括一溝槽11，溝槽11位於撓性部10之表面，且溝槽11具有一第一端111與一第二端112，第一端111與第二端112之間具有一間距，也就是說，第一端111與第二端112彼此不相連，溝槽11不會形成為一封閉區域。 FIG. 1A is a schematic view showing a bionic fixation device 1 according to a first embodiment of the present invention. The bionic fixture 1 includes a flexible portion 10 including a groove 11 on the surface of the flexible portion 10, and the groove 11 has a first end 111 and a second end 112. There is a distance between the one end 111 and the second end 112, that is, the first end 111 and the second end 112 are not connected to each other, and the groove 11 is not formed as a closed area.
第1B圖繪示本發明第一實施例之仿生固定裝置1(在Y-Z平面)的側視圖。如第1B圖所示，本發明第一實施例之仿生固定裝置1的溝槽11，在Y-Z平面上係沿著一第一方向D1，在撓性部10之表面延伸。在本實施例中，第一方向D1係垂直於仿生固定裝置1的一受力方向。在一實施例中，仿生固定裝置1的受力方向例如是平行於Z方向。 Fig. 1B is a side view showing the bionic fixing device 1 (in the Y-Z plane) of the first embodiment of the present invention. As shown in Fig. 1B, the groove 11 of the bionic fixation device 1 of the first embodiment of the present invention extends in the Y-Z plane along a first direction D1 on the surface of the flexible portion 10. In the present embodiment, the first direction D1 is perpendicular to a direction of force of the bionic fixing device 1. In an embodiment, the direction of force of the biomimetic fixture 1 is, for example, parallel to the Z direction.
第1C圖繪示本發明第一實施例之仿生固定裝置1的溝槽11(在X-Y平面)的示意圖。第1C圖係自另一角度(另一平面)觀察仿生固定裝置1之溝槽11的結構。在本實施例中，仿生固定裝置1的溝槽11在一第一平面(X-Y平面)上係沿著一軌跡，在撓性部10之表面延伸。此處，第一平面係垂直於仿生固定裝置1的受力方向(Z方向)。舉例來說，如第1C圖所示，溝槽11在X-Y平面上係沿著軌跡T1，在撓性部10之表面延伸。 FIG. 1C is a schematic view showing the groove 11 (in the X-Y plane) of the bionic fixing device 1 of the first embodiment of the present invention. Fig. 1C is a view showing the structure of the groove 11 of the biomimetic fixing device 1 from another angle (another plane). In the present embodiment, the groove 11 of the bionic fixing device 1 extends along the surface of the flexible portion 10 along a trajectory in a first plane (X-Y plane). Here, the first plane is perpendicular to the direction of force (Z direction) of the biomimetic fixture 1. For example, as shown in FIG. 1C, the groove 11 extends along the track T1 in the X-Y plane on the surface of the flexible portion 10.
在本發明實施例中，軌跡係為一弧度小於2π的弧線，例如第1C圖中所繪示之軌跡T1，係為一沿著弧度0至π的弧線。但本發明並未限定於此，在不同實施例中，軌跡也可為沿著其他的弧度所形成之弧線。 In the embodiment of the present invention, the trajectory is an arc having an arc of less than 2π, for example, the trajectory T1 depicted in FIG. 1C is an arc along an arc of 0 to π. However, the present invention is not limited thereto, and in various embodiments, the trajectory may also be an arc formed along other radians.
第1D~1F圖繪示本發明其他實施例之仿生固定裝置1的溝槽11(在X-Y平面)的示意圖。在第1D圖中，軌跡T2例如是一沿著弧度π/2至3π/2的弧線；在第1E圖中，軌跡T3例如是一沿著弧度π至2π的弧線；在1F圖中，軌跡T4例如是一沿著弧度-π/2至π/2的弧線。 1D-1F are schematic views showing the groove 11 (in the X-Y plane) of the bionic fixation device 1 according to another embodiment of the present invention. In the 1D diagram, the trajectory T2 is, for example, an arc along an arc of π/2 to 3π/2; in the 1E diagram, the trajectory T3 is, for example, an arc along an arc of π to 2π; in the 1F map, the trajectory T4 is, for example, an arc along the arc of -π/2 to π/2.
要注意的是，雖然本發明第1C圖所繪示之軌跡T1、第1D圖所繪示之軌跡T2、第1E圖所繪示之軌跡T3與第1F圖所繪示之軌跡T4皆為弧度為π的弧線，但本發明並未限定於此。相對地，本發明實施例之軌跡係為一弧度小於2π的弧線，也就是說，使仿生固定裝置1之溝槽11的第一端111與第二端112彼此不相連，即可作為本發明實施例之溝槽11。 It should be noted that although the track T1 shown in FIG. 1C of the present invention, the track T2 shown in FIG. 1D, the track T3 shown in FIG. 1E, and the track T4 shown in the first FIG. It is an arc of π, but the present invention is not limited thereto. In contrast, the trajectory of the embodiment of the present invention is an arc having an arc of less than 2π, that is, the first end 111 and the second end 112 of the groove 11 of the bionic fixing device 1 are not connected to each other, and thus can be used as the present invention. The trench 11 of the embodiment.
上述藉由第一平面(即X-Y平面)與第二平面(即Y-Z平面)觀察本發明第一實施例之溝槽11，係將本發明第一實施例之仿生固定裝置1簡化並以一圓柱、圓錐或類似的形狀表示，也就是說，溝槽11可大致上沿著例如是平行於圓柱或圓錐的圓周方向，在撓性部10之表面延伸。 The groove 11 of the first embodiment of the present invention is observed by the first plane (ie, the XY plane) and the second plane (ie, the YZ plane), and the bionic fixing device 1 of the first embodiment of the present invention is simplified and has a cylinder. The shape of the cone or the like is indicated, that is to say, the groove 11 can extend over the surface of the flexible portion 10 substantially along a circumferential direction, for example parallel to the cylinder or the cone.
由於本發明第一實施例之仿生固定裝置1具有溝槽11，可利用溝槽11所形成的微小空間作為承受外力時的緩衝。舉例來說，在本實施例中，假設對仿生固定裝置1施加平行於Z方向、大小為100N的外力，仿生固定裝置1會產生大約4.998×10-2mm之位移，此位移可作為承受外力時的緩衝，防止應力集中及應力遮蔽，有效降低仿生固定裝置1的彈性模數，避免鬆脫，或者讓生物體產生組織凹陷、壞死、磨損的情況。 Since the bionic fixing device 1 of the first embodiment of the present invention has the groove 11, the minute space formed by the groove 11 can be utilized as a buffer for receiving an external force. For example, in the present embodiment, assuming that an external force parallel to the Z direction and having a size of 100 N is applied to the bionic fixing device 1, the bionic fixing device 1 generates a displacement of about 4.998 × 10 -2 mm, which can be used as an external force. The buffering of the time prevents stress concentration and stress shielding, effectively reduces the elastic modulus of the bionic fixing device 1, avoids loosening, or causes the living body to have tissue depression, necrosis, and wear.
第2A圖繪示本發明第二實施例之仿生固定裝置2的示意圖。與第一實施例類似，仿生固定裝置2同樣包括一撓性部20。與第一實施例不同之處，係在於仿生固定裝置2包括一第一溝槽21與一第二溝槽22。第一溝槽21與第二溝槽22皆位撓性部20之表面，且具有一第一端與一第二端(未繪示)。同樣地，第一溝槽21與第二溝槽22個別的第一端與第二端之間具有一間距，也就是說，第一端與第二端彼此不相連，第一溝槽21與第二溝槽22皆不會形成為一封閉區域。 FIG. 2A is a schematic view showing the bionic fixing device 2 of the second embodiment of the present invention. Similar to the first embodiment, the biomimetic fixture 2 also includes a flexible portion 20. The difference from the first embodiment is that the biomimetic fixing device 2 includes a first groove 21 and a second groove 22. The first trench 21 and the second trench 22 are both on the surface of the flexible portion 20 and have a first end and a second end (not shown). Similarly, the first trench 21 and the second trench 22 have a spacing between the first end and the second end of the second trench 22, that is, the first end and the second end are not connected to each other, and the first trench 21 is Neither the second trench 22 is formed as a closed region.
第2B圖繪示本發明第二實施例之仿生固定裝置2(在Y-Z平面)的側視圖。如第2B圖所示，本發明第二實施例之仿生固定裝置2的第一溝槽21，在Y-Z平面上係沿著一第一方向D1，在撓性部20之表面延伸。本發明第二實施例之仿生固定裝置2的第二溝槽22，在Y-Z平面上係沿著一第二方向D2，在撓性部20之表面延伸。在本實施例中，第一方向D1與第二方向D2係垂直於仿生固定裝置2的一受力方向(受力方向例如是平行於Z方向)，而第二方向D2與第一方向D1相反。 Fig. 2B is a side view showing the bionic fixing device 2 (in the Y-Z plane) of the second embodiment of the present invention. As shown in Fig. 2B, the first groove 21 of the bionic fixation device 2 of the second embodiment of the present invention extends in the Y-Z plane along a first direction D1 on the surface of the flexible portion 20. The second groove 22 of the bionic fixation device 2 of the second embodiment of the present invention extends in the Y-Z plane along a second direction D2 on the surface of the flexible portion 20. In this embodiment, the first direction D1 and the second direction D2 are perpendicular to a direction of force of the bionic fixing device 2 (the force direction is, for example, parallel to the Z direction), and the second direction D2 is opposite to the first direction D1. .
以下係自另一角度(另一平面)觀察仿生固定裝置2之第一溝槽21與第二溝槽22的結構。在本實施例中，仿生固定裝置2的第一溝槽21在X-Y平面上係沿著如第1C圖所示之軌跡T1，在撓性部20之表面延伸，也就是說，第一溝槽21係沿著弧度0至π的弧線，在撓性部20之表面延伸。仿生固定裝置2的第二溝槽22在X-Y平面上係沿著如第1E圖所示之軌跡T3，在撓性部20之表面延伸，也就是說，第二溝槽22係沿著 弧度π至2π的弧線，在撓性部20之表面延伸。 The structure of the first groove 21 and the second groove 22 of the biomimetic fixture 2 is observed from another angle (another plane). In the present embodiment, the first groove 21 of the bionic fixing device 2 extends along the surface T1 as shown in FIG. 1C on the XY plane, that is, on the surface of the flexible portion 20, that is, the first groove. The 21 series extends along the surface of the flexible portion 20 along an arc of curvature 0 to π. The second groove 22 of the biomimetic fixture 2 extends along the surface T3 as shown in FIG. 1E on the X-Y plane, and extends over the surface of the flexible portion 20, that is, the second groove 22 is along An arc having an arc of π to 2π extends on the surface of the flexible portion 20.
本發明第二實施例並未限定第一溝槽21與第二溝槽22皆為弧度為π的弧線。相對地，本發明實施例之軌跡係為一弧度小於2π的弧線，也就是說，使仿生固定裝置2之第一溝槽21與第二溝槽22個別的第一端與第二端彼此不相連，即可作為本實施例之溝槽。 The second embodiment of the present invention does not define that the first trench 21 and the second trench 22 are both arcs having an arc of π. In contrast, the trajectory of the embodiment of the present invention is an arc having an arc of less than 2π, that is, the first end and the second end of the first groove 21 and the second groove 22 of the bionic fixture 2 are not adjacent to each other. Connected, it can be used as the groove of this embodiment.
在本實施例中，假設對仿生固定裝置2施加平行於Z方向、大小為100N的外力，仿生固定裝置2會產生大約3.647×10-2mm之位移；假設外力大小增加為137N，仿生固定裝置2會產生大約4.996×10-2mm之位移。同樣地，這些位移可作為承受外力時的緩衝，有效降低仿生固定裝置2的彈性模數。 In the present embodiment, it is assumed that an external force parallel to the Z direction and having a size of 100 N is applied to the bionic fixing device 2, and the bionic fixing device 2 generates a displacement of about 3.647×10 -2 mm; assuming that the external force is increased to 137 N, the bionic fixing device 2 will produce a displacement of approximately 4.996 × 10 -2 mm. Similarly, these displacements can serve as a cushion for receiving an external force, effectively reducing the elastic modulus of the bionic fixing device 2.
第3A圖繪示本發明第三實施例之仿生固定裝置3的示意圖。與第二實施例類似，仿生固定裝置3同樣包括一撓性部30。與第二實施例不同之處，係在於仿生固定裝置3除了包括一第一溝槽31、一第二溝槽32以外，更包括一第三溝槽33與一第四溝槽34。第一溝槽31、第二溝槽32、第三溝槽33與第四溝槽34皆位於撓性部30之表面。 FIG. 3A is a schematic view showing the bionic fixation device 3 according to the third embodiment of the present invention. Similar to the second embodiment, the biomimetic fixture 3 also includes a flexible portion 30. The difference from the second embodiment is that the bionic fixing device 3 further includes a third groove 33 and a fourth groove 34 in addition to a first groove 31 and a second groove 32. The first trench 31, the second trench 32, the third trench 33, and the fourth trench 34 are all located on the surface of the flexible portion 30.
第3B圖繪示本發明第三實施例之仿生固定裝置3(在Y-Z平面)的側視圖。本發明第三實施例之第一溝槽31與第三溝槽33類似於本發明第二實施例之第一溝槽21；本發明第三實施例之第二溝槽32與第四溝槽34類似於本發明第二實施例之第二溝槽22。此外，如第3A、3B圖所示，第一溝槽31、第二溝槽32、第三溝槽33與第四溝槽34係依序由上而 下形成於撓性部30之表面。但本發明並未限定於此，第一溝槽31、第二溝槽32、第三溝槽33與第四溝槽34在撓性部30之表面之順序也可與第3A、3B圖所繪示的結構不同。 Fig. 3B is a side view showing the bionic fixing device 3 (in the Y-Z plane) of the third embodiment of the present invention. The first trench 31 and the third trench 33 of the third embodiment of the present invention are similar to the first trench 21 of the second embodiment of the present invention; the second trench 32 and the fourth trench of the third embodiment of the present invention 34 is similar to the second trench 22 of the second embodiment of the present invention. In addition, as shown in FIGS. 3A and 3B, the first trench 31, the second trench 32, the third trench 33, and the fourth trench 34 are sequentially arranged. The lower surface is formed on the surface of the flexible portion 30. However, the present invention is not limited thereto, and the order of the first trench 31, the second trench 32, the third trench 33, and the fourth trench 34 on the surface of the flexible portion 30 may be the same as that of the third and third embodiments. The structure shown is different.
如第3B圖所示，本發明第三實施例之仿生固定裝置3的第一溝槽31與第三溝槽33，在Y-Z平面上係沿著一第一方向D1，在撓性部30之表面延伸。本發明第三實施例之仿生固定裝置3的第二溝槽32與第四溝槽34，在Y-Z平面上係沿著一第二方向D2，在撓性部30之表面延伸。在本實施例中，第一方向D1與第二方向D2係垂直於仿生固定裝置3的一受力方向(受力方向例如是平行於Z方向)，而第二方向D2與第一方向D1相反。 As shown in FIG. 3B, the first groove 31 and the third groove 33 of the bionic fixing device 3 according to the third embodiment of the present invention are along the first direction D1 in the YZ plane, and are in the flexible portion 30. The surface extends.

The structure shown is different.
本發明第五實施例之仿生固定裝置5與第四實施例之仿生固定裝置4之不同之處，係在於仿生固定裝置5第二溝槽52與第三溝槽53之順序與仿生固定裝置4第二溝槽42與第三溝槽43之順序相反。如第5B圖所示，本發明第五實施例之仿生固定裝置5的第二溝槽52類似於第四實施例之仿生固定結構4的第三溝槽43，在Y-Z平面上係沿著一第二方向D2，在撓性部50之表面延伸。本發明第五實施例之仿生固定裝置5的第三溝槽53類似於第四實施例之仿生固定結構4的第二溝槽42，在Y-Z平面上係沿著一第三方向D3，在撓性部50之表面延伸。 The bionic fixing device 5 of the fifth embodiment of the present invention is different from the bionic fixing device 4 of the fourth embodiment in the order of the second groove 52 and the third groove 53 of the bionic fixing device 5 and the bionic fixing device 4 The second groove 42 is opposite to the order of the third groove 43.

The surface of the sexual portion 50 extends.
自另一角度(另一平面)觀察仿生固定裝置5之結構，在本實施例中，仿生固定裝置5的第二溝槽52在X-Y平面上係沿著如第1E圖 所示之軌跡T3，在撓性部50之表面延伸，也就是說，第二溝槽52係沿著弧度π至2π的弧線，在撓性部50之表面延伸。仿生固定裝置5的的第三溝槽53在X-Y平面上係沿著如第1F圖所示之軌跡T4，在撓性部50之表面延伸，也就是說，第三溝槽53係沿著弧度-π/2至π/2的弧線，在撓性部50之表面延伸。其它和第四實施例相同之處，在此不多加贅述。 The structure of the bionic fixing device 5 is observed from another angle (the other plane). In the present embodiment, the second groove 52 of the bionic fixing device 5 is along the X-Y plane along the first E-picture. The illustrated trajectory T3 extends over the surface of the flexure 50, that is, the second groove 52 extends along the surface of the flexure 50 along an arc of π to 2π. The third groove 53 of the biomimetic fixture 5 extends along the trajectory T4 as shown in FIG. 1F on the surface of the flexible portion 50 in the XY plane, that is, the third groove 53 is along the arc. An arc of -π/2 to π/2 extends on the surface of the flexible portion 50. Others are the same as the fourth embodiment, and are not described here.
本發明第五實施例之第一溝槽51、第二溝槽52、第三溝槽53與第四溝槽54係以弧度為π的弧線為例說明，但本發明並未限定於此。 In the fifth embodiment of the present invention, the first trench 51, the second trench 52, the third trench 53, and the fourth trench 54 are exemplified by an arc having an arc of π, but the present invention is not limited thereto.
在本實施例中，假設對仿生固定裝置5施加平行於Z方向、大小為100N的外力，仿生固定裝置5會產生大約1.087×10-1mm之位移，此位移可作為承受外力時的緩衝，有效降低仿生固定裝置5的彈性模數。 In the present embodiment, it is assumed that an external force parallel to the Z direction and having a size of 100 N is applied to the bionic fixing device 5, and the bionic fixing device 5 generates a displacement of about 1.087 × 10 -1 mm, which can be used as a buffer for receiving an external force. The elastic modulus of the bionic fixing device 5 is effectively reduced.
在上述第一至第五實施例中，皆對仿生固定裝置施加平行於Z方向、大小為100N的外力，並測定其產生的位移。同樣地，係以一比較例進行受力測試，並比較此比較例與上述第一至第五實施例之差異。在此，比較例係為一無撓性部的仿生固定裝置，也就是說，仿生固定裝置之表面不具有任何的溝槽與孔洞。 In the above-described first to fifth embodiments, external forces parallel to the Z direction and having a size of 100 N were applied to the bionic fixing device, and the displacement generated was measured.

對比較例之仿生固定裝置施加平行於Z方向、大小為100N的外力，比較例之仿生固定裝置會產生大約9.023×10-4mm之位移，此位移量明顯少於上述各實施例的位移量。也就是說，比較例之結構，作為承受外力時之緩衝的效果，明顯低於本發明各實施例之仿生固定裝置，容易產生鬆脫，或者讓生物體產生組織凹陷、壞死、磨損的情況。 An external force parallel to the Z direction and having a size of 100 N was applied to the bionic fixing device of the comparative example, and the bionic fixing device of the comparative example produced a displacement of about 9.023 × 10 -4 mm, which was significantly smaller than the displacement of each of the above embodiments. . That is to say, the structure of the comparative example has a effect of being buffered when subjected to an external force, and is significantly lower than the bionic fixing device of each embodiment of the present invention, which is liable to cause loosening, or causes the living body to have tissue depression, necrosis, and abrasion.

The fifth groove 65 and the sixth groove 66 are U-shaped on the surface of the flexible portion and opposed to each other. As shown, the fifth trench 65 and the sixth trench 66 may be disposed within the spacing S between the first ends 611, 621, 631, 641 and the second ends 612, 622, 632, 642, but The five trenches 65 and the sixth trenches 66 are not connected to the first trenches 61, the second trenches 62, the third trenches 63, and the fourth trenches 64.
此外，本發明第六實施例之仿生固定裝置6也可包括一螺紋部91。螺紋部91環繞於仿生固定裝置6之表面，且螺紋部91與撓性部60係為一體成型。螺紋部91可使仿生固定裝置6在植入生物體後，與植入之周邊的生物組織固定。 Further, the bionic fixing device 6 of the sixth embodiment of the present invention may also include a threaded portion 91. The threaded portion 91 surrounds the surface of the bionic fixing device 6, and the threaded portion 91 and the flexible portion 60 are integrally formed. The threaded portion 91 allows the biomimetic fixation device 6 to be fixed to the biological tissue surrounding the implant after implantation into the living body.
第7圖繪示本發明第七實施例之仿生固定裝置7的示意圖。仿生固定裝置7包括一撓性部70，撓性部70包括溝槽71。溝槽71在Y-Z平面上係沿著一第四方向D4，在撓性部70之表面延伸。在本實施例中，第四方向係平行於仿生固定裝置7的一受力方向。 FIG. 7 is a schematic view showing a bionic fixing device 7 according to a seventh embodiment of the present invention. The biomimetic fixture 7 includes a flexure 70 that includes a groove 71. The groove 71 extends along the surface of the flexible portion 70 along a fourth direction D4 in the Y-Z plane. In the present embodiment, the fourth direction is parallel to a direction of force of the bionic fixture 7.
在本發明第七實施例中，仿生固定裝置7更可包括複數個孔洞72、73、74。在本實施例中，孔洞72可例如是三角形，孔洞73可例如是梯形，孔洞74可例如是由三角形(或梯形)與矩形所組合成的幾何形狀。這些孔洞與溝槽71使撓性部70之表面形成複數個外力承受區75。 In the seventh embodiment of the present invention, the bionic fixing device 7 further includes a plurality of holes 72, 73, 74. In the present embodiment, the holes 72 may be, for example, triangular, and the holes 73 may be, for example, trapezoidal, and the holes 74 may be, for example, a geometric shape in which a triangle (or trapezoid) and a rectangle are combined. These holes and grooves 71 form a plurality of external force receiving regions 75 on the surface of the flexible portion 70.
在本實施例中，這些外力承受區75包括一第一子區域751與一第二子區域752。第一子區域751係於第一方向D1上延伸，第二子區域752與第一子區域751之夾角為第一夾角θ1，第一夾角θ1可例如介於0至45度，此外，第一方向D1垂直於仿生固定裝置7的受力方向。由於本發明第七實施例之仿生固定裝置7具有溝槽71與複數個孔洞72、73、74，使撓性部70之表面形成上述外力承受區，這樣的結構可使仿生固定裝置7 吸收更大的外力，防止應力集中及應力遮蔽，能有降低升固定裝置7的彈性模數，避免在承受外力時發生鬆脫情況。 In the present embodiment, the external force receiving regions 75 include a first sub-region 751 and a second sub-region 752. The first sub-region 751 extends in the first direction D1, the angle between the second sub-region 752 and the first sub-region 751 is a first angle θ1, and the first angle θ1 can be, for example, between 0 and 45 degrees. The direction D1 is perpendicular to the direction of force of the bionic fixture 7. Since the bionic fixing device 7 of the seventh embodiment of the present invention has the groove 71 and the plurality of holes 72, 73, 74, the surface of the flexible portion 70 forms the external force receiving portion, and such a structure enables the bionic fixing device 7 Absorbing a larger external force, preventing stress concentration and stress shielding, can reduce the elastic modulus of the lifting fixture 7, and avoid loosening when subjected to external force.
要注意的是，雖然本發明第七實施例係以孔洞72為三角形、孔洞73為梯形且孔洞74為由三角形(或梯形)與矩形所組合成的幾何形狀為例進行說明，但本發明並未限定於此。相對地，本發明實施例之孔洞的形狀係與溝槽71配合，以形成複數個外力承受區75，這些外力承受區75須包括一第一子區域751於第一方向D1上延伸，且包括一第二子區域752與第一子區域751之夾角介於0至45度。若夾角(第一夾角θ1)大於45度，則仿生固定裝置7之彈性模數將明顯增加。 It should be noted that although the seventh embodiment of the present invention is described by taking the hole 72 as a triangle, the hole 73 as a trapezoid, and the hole 74 as a geometric shape in which a triangle (or a trapezoid) and a rectangle are combined, the present invention is described. Not limited to this. In contrast, the shape of the hole in the embodiment of the present invention is matched with the groove 71 to form a plurality of external force receiving regions 75.

此外，本發明上述各實施例，皆可以積層製造(Additive Manufacturing,AM)製程，達到上述複雜的微結構。其中無論是仿生固定裝置之撓性部、螺紋部與外力承受區等結構皆為一體成型。再者，本發明實施例之各種不同的孔洞大小、形狀與排列方式，也可輕易以積層製造製程完成。相對地，傳統以特殊燒結或表面塗佈製程，再以雷射進行開孔之製程方法，不僅製程複雜，製造成本也較高，不適於用以生產本發明實施例之結構。 In addition, all of the above embodiments of the present invention can be implemented by an additive manufacturing (AM) process to achieve the above-mentioned complicated microstructure. Among them, the flexible part of the bionic fixing device, the threaded part and the external force receiving area are integrally formed. Furthermore, the various hole sizes, shapes and arrangements of the embodiments of the present invention can also be easily accomplished by a laminate manufacturing process.

積層製造(AM)還具有快速原型(Rapid Prototyping,RP)、快速製造(Rapid Manufacturing,RM)或3D列印(3D Printing)等稱呼，2009年由美國材料試驗協會(American Society for Testing and Materials，ASTM)進行正名為積層製造。研究學者將積層製造分成七大類型，如下表一所示，包含：光聚合固化技術(Vat Photopolymerization)、材料噴塗成型技術(Material Jetting)、黏著劑噴塗成型技術(Binder Jetting)、材料擠製成型技術(Material Extrusion)、粉體熔化成型技術(Powder Bed Fusion)、疊層製造成型技術(Sheet Lamination與直接能量沉積技術(Directed Energy Deposition)。 The laminate manufacturing (AM) also has the titles of Rapid Prototyping (RP), Rapid Manufacturing (RM) or 3D Printing. In 2009, the American Society for Testing and Materials (American Society for Testing and Materials) ASTM) is called the manufacturing of laminates. Researchers divide laminated manufacturing into seven types, as shown in Table 1, including: Vat Photopolymerization, Material Jetting, Binder Jetting, and material extrusion. Material Extrusion, Powder Bed Fusion, Sheet Lamination and Directed Energy Deposition.
積層製造的製造特色，係在於將三維(3D)圖檔切成二維(2D)斷面，再依二維斷面逐層加工並逐層堆疊成三維物件。相對於傳統 的加工方式，積層製造製程可避免材料浪費，更適合高複雜形貌、客製化之中小量生產應用。 The manufacturing feature of laminated manufacturing is to cut three-dimensional (3D) image files into two-dimensional (2D) sections, and then process them layer by layer according to two-dimensional sections and stack them into three-dimensional objects layer by layer. Relative to tradition The processing method, the multi-layer manufacturing process can avoid material waste, and is more suitable for high-complexity, customized and small-scale production applications.
在製造本發明各實施例之仿生固定裝置時，係將這些仿生固定裝置的三維數位模型切層為20~50μm厚度的二維斷面，在低氧環境(O2濃度小於10,000ppm)之密封建構區中，透過一供料單元將粒徑小於25μm之粉體材料(金屬、合金、陶瓷或高分子生醫材料)，進行厚度20~50μm的平面鋪層。 In the manufacture of the biomimetic fixing device of each embodiment of the present invention, the three-dimensional digital model of the biomimetic fixing device is cut into a two-dimensional section having a thickness of 20 to 50 μm, and sealed in a low oxygen environment (O 2 concentration is less than 10,000 ppm). In the construction zone, a powder material (metal, alloy, ceramic or polymer biomedical material) having a particle diameter of less than 25 μm is deposited through a feeding unit to a flat layer having a thickness of 20 to 50 μm.
接著，再以光纖雷射光束(波長1070nm)，透過掃描振鏡導引聚焦光束(50~150μm)至鋪層之區域。聚焦光束依照所需之二維斷面移動(移動速度為500~1500mm/s)，使聚焦光束照射之粉體材料達到材料的熔點，進而反覆依二維斷面形狀堆疊成三維的仿生固定裝置。這樣的製程方式可達到傳統加工方式難以製作的複雜形貌、內流道與內結構。 Then, the laser beam (wavelength 1070 nm) is used to guide the focused beam (50-150 μm) through the scanning galvanometer to the area of the layer. The focused beam moves according to the required two-dimensional cross-section (moving speed is 500~1500mm/s), so that the powder material irradiated by the focused beam reaches the melting point of the material, and then stacked in a three-dimensional cross-sectional shape to form a three-dimensional bionic fixture. . Such a process can achieve complex topography, internal flow paths and internal structures that are difficult to fabricate in conventional processing methods.
