以下參考本發明一實施型態中的骨固定板1的圖式來進行說明。骨固定板1係如圖1及圖2所示般，為具有直線狀縱軸A的板狀構件。骨固定板1於厚度方向觀察的俯視圖中呈T字型，具有：於一端側上的第一區域1A，其係直線狀地沿著垂直於縱軸A的橫軸B延伸；於另一端側上的第二區域1B，其係直線狀地沿著縱軸A延伸。 於以下說明當中，長度方向係與縱軸A平行之方向，寬度方向係與橫軸B平行之方向，厚度方向係垂直於縱軸A及橫軸B之厚度上的方向。長度、寬度、厚度係分別為長度方向、寬度方向及厚度方向之尺寸。The description will be made below with reference to the drawings of the bone fixation plate 1 in an embodiment of the present invention. The bone fixation plate 1 is a plate-shaped member having a linear longitudinal axis A as shown in FIGS. 1 and 2. The bone fixation plate 1 is T-shaped in a plan view viewed in the thickness direction, and has: a first area 1A on one end side, which linearly extends along a horizontal axis B perpendicular to the longitudinal axis A; on the other end side The upper second area 1B extends linearly along the longitudinal axis A. In the following description, the length direction is a direction parallel to the vertical axis A, the width direction is a direction parallel to the horizontal axis B, and the thickness direction is a direction perpendicular to the thickness of the vertical axis A and the horizontal axis B. Length, width, and thickness are the dimensions in the length direction, width direction, and thickness direction, respectively.

第一區域1A係比第二區域B還要往寬度方向之兩側突出，第一區域1A的寬度比第二區域1B的寬度還要大。此外，第一區域1A的長度小於第二區域1B的長度。The first area 1A protrudes further to both sides of the width direction than the second area B, and the width of the first area 1A is larger than the width of the second area 1B. In addition, the length of the first region 1A is smaller than the length of the second region 1B.

如圖1及圖3所示，骨固定板1具備分別貫穿於厚度方向的複數個插入孔2，各插入孔2係受到環狀的邊緣部3包圍。各插入孔2當中插有用於將骨固定板1固定至骨頭的螺釘S(參考圖6)。螺釘S係為於頭部外圍面上具有螺紋的鎖定螺釘(locking screw)。如圖4所示，插入孔2係為用於緊固螺釘S頭部的內螺紋。As shown in FIGS. 1 and 3, the bone fixation plate 1 includes a plurality of insertion holes 2 respectively penetrating in the thickness direction, and each insertion hole 2 is surrounded by an annular edge portion 3. A screw S for fixing the bone fixing plate 1 to the bone is inserted in each insertion hole 2 (refer to FIG. 6). The screw S is a locking screw with threads on the outer surface of the head. As shown in Fig. 4, the insertion hole 2 is an internal thread for fastening the head of the screw S.

第一區域1A具有一個以上的插入孔2，第二區域1B具有兩個以上的插入孔2。於參考圖式當中，第一區域1A具有兩個插入孔2，第二區域1B具有三個插入孔2。第一區域1A的插入孔2的數量亦可為僅有1個或是3個以上。第二區域1B的插入孔2的數量亦可為僅有2個或是4個以上。 第一區域1A的2個插入孔2係排列於寬度方向上，於寬度方向上往相反方向偏離縱軸A。第二區域1B的所有的插入孔2係於長度方向上互相間隔，並於縱軸A上排成一列。The first area 1A has one or more insertion holes 2, and the second area 1B has two or more insertion holes 2. In the reference drawings, the first area 1A has two insertion holes 2, and the second area 1B has three insertion holes 2. The number of insertion holes 2 in the first region 1A can also be only one or more than three. The number of insertion holes 2 in the second region 1B can also be only two or more than four. The two insertion holes 2 of the first region 1A are arranged in the width direction and deviate from the longitudinal axis A in the opposite direction in the width direction. All the insertion holes 2 in the second region 1B are spaced apart from each other in the length direction, and are arranged in a row on the longitudinal axis A.

骨固定板1係具有第一薄層區域4及第二薄層區域5。 第一薄層區域4係設置於第一區域1A及第二區域1B之間。第一薄層區域4的一端係連接至第一區域1A的2個插入孔2的邊緣部3；第一薄層區域4的另一端係連接至最靠第二區域1B一端側的插入孔2的邊緣部3。 第二薄層區域5設置於第二區域1B的插入孔2間，各第2薄層區域5的兩端連接至邊緣部3。 第一薄層區域4的長度大於第二薄層區域5的長度。The bone fixation plate 1 has a first thin layer area 4 and a second thin layer area 5. The first thin layer region 4 is disposed between the first region 1A and the second region 1B. One end of the first thin layer region 4 is connected to the edge portion 3 of the two insertion holes 2 of the first region 1A; the other end of the first thin layer region 4 is connected to the insertion hole 2 closest to the one end of the second region 1B的边部3。 The edge part 3. The second thin layer region 5 is provided between the insertion holes 2 of the second region 1B, and both ends of each second thin layer region 5 are connected to the edge portion 3. The length of the first thin layer region 4 is greater than the length of the second thin layer region 5.

如圖2及圖3所示，第一薄層區域4及第二薄層區域5的各個厚度係小於邊緣部3的厚度，各薄層區域4, 5與邊緣部3之間形成厚度方向上的高低差。因此，第一薄層區域4及第二薄層區域5分別具有低於邊緣部3的剛性，且於各薄層區域4, 5及邊緣部3之間，剛性為不連續地變化。此外，於參考圖式當中，邊緣部3的寬度方向的兩端部係經倒角處理，邊緣部3的厚度係指排除倒角部分及溝槽9(後述)的部分之厚度。 此外，第一薄層區域4及第二薄層區域5的寬度分別小於第二區域1B的邊緣部3的寬度。 此外，垂直於第一薄層區域4的縱軸A的橫向剖面於長度方向的大致全長上為一致不變，因此，第一薄層區域4的剛性於長度方向上係為固定。As shown in Figures 2 and 3, the thickness of each of the first thin layer region 4 and the second thin layer region 5 is smaller than the thickness of the edge portion 3. The thickness of each thin layer region 4, 5 and the edge portion 3 is formed in the thickness direction. The height difference. Therefore, the first thin layer region 4 and the second thin layer region 5 respectively have lower rigidity than the edge portion 3, and the rigidity varies discontinuously between the thin layer regions 4, 5 and the edge portion 3. In addition, in the reference drawings, both ends in the width direction of the edge portion 3 are chamfered, and the thickness of the edge portion 3 refers to the thickness of the portion excluding the chamfered portion and the groove 9 (described later). In addition, the widths of the first thin-layer region 4 and the second thin-layer region 5 are respectively smaller than the width of the edge portion 3 of the second region 1B. In addition, the transverse cross-section perpendicular to the longitudinal axis A of the first thin-layer region 4 is uniform over the substantially entire length in the longitudinal direction. Therefore, the rigidity of the first thin-layer region 4 is constant in the longitudinal direction.

骨固定板1的一端的側面上，形成有凹部6，其係於長度方向內側凹陷，且導銷P徑向嵌入其中。藉著使凹度6貼齊插入骨頭中的導銷P，可使骨固定板1對導銷P及骨頭作暫時性的定位。 也可以在第一區域1A及第二區域1B的至少其中之一設置導孔11，其中導孔11沿厚度方向貫穿並且導銷P插入到導孔11中。On the side surface of one end of the bone fixation plate 1, a recess 6 is formed, which is recessed in the longitudinal direction and the guide pin P is radially embedded in it. By making the concavity 6 fit the guide pin P inserted into the bone, the bone fixing plate 1 can temporarily position the guide pin P and the bone. It is also possible to provide a guide hole 11 in at least one of the first area 1A and the second area 1B, wherein the guide hole 11 penetrates in the thickness direction and the guide pin P is inserted into the guide hole 11.

骨固定板1具有於厚度方向上相對的一對表面7, 8。如圖5及圖6所示般，一邊的表面7係為配置於靠近骨頭側的內側表面，另一邊的表面8係為配置於骨頭相反側的外側表面。如圖5所示，內側表面7係於厚度方向上形成沿著縱軸A的凹陷－即溝槽9。將骨固定板1配置於骨X的彎曲表面時，內側表面7係於溝槽9的兩端與骨X接觸，以確保溝槽9的內部表面與骨X的表面之間的縫隙。The bone fixation plate 1 has a pair of surfaces 7, 8 opposite in the thickness direction. As shown in FIGS. 5 and 6, the surface 7 on one side is arranged on the inner surface near the bone, and the surface 8 on the other side is arranged on the outer surface on the opposite side of the bone. As shown in FIG. 5, the inner surface 7 is formed with a depression along the longitudinal axis A—that is, a groove 9 in the thickness direction. When the bone fixation plate 1 is arranged on the curved surface of the bone X, the inner surface 7 is tied to the two ends of the groove 9 in contact with the bone X to ensure a gap between the inner surface of the groove 9 and the surface of the bone X.

接著，針對骨固定板1的使用方法一例進行說明。 骨固定板1係使用於截骨手術或是骨折治療中。圖6係表示將骨固定板1使用於高位脛骨截骨手術(HTO, High tibial osteotomy)的例子。 於HTO當中，係由脛骨X的高位外側表面朝向內側，於相對於脛骨X的縱軸傾斜之方向形成2個切口，並使用特定的器具去除2個切口之間的骨片。於此狀態下，於骨片的切除部位的內側表面側上形成樞轉部H，切除部位的上側的骨骺X1能夠以樞轉部H為中心對骨幹X2作擺動。Next, an example of how to use the bone fixation plate 1 will be described. The bone fixation plate 1 is used in osteotomy or fracture treatment. Fig. 6 shows an example of using the bone fixation plate 1 for high tibial osteotomy (HTO, High tibial osteotomy). In HTO, two incisions are formed from the high lateral surface of the tibia X toward the inner side, in a direction inclined with respect to the longitudinal axis of the tibia X, and the bone fragments between the two incisions are removed using a specific tool. In this state, a pivot portion H is formed on the inner surface side of the excision site of the bone fragment, and the epiphysis X1 on the upper side of the excision site can swing the bone shaft X2 with the pivot portion H as the center.

接著，從內側將導銷P－也就是作為骨固定板1相對於脛骨X的位置基準的導銷P，插入至骨骺X1中，接著，將第一區域1A及第二區域1B分別配置於骨骺X1及骨幹X2的內側表面，使骨固定板1於凹部6處抵靠導銷P，藉此進行骨固定板1對骨骺X1及骨幹X2的定位。關於導銷P相對於骨骺X1的位置係設定為使得第一薄層區域4配置於樞轉部H。於此狀態下確認骨固定板1的形狀與脛骨X的形狀之間的差。Next, the guide pin P—that is, the guide pin P used as a reference for the position of the bone fixation plate 1 with respect to the tibia X—is inserted into the epiphysis X1 from the inside, and then the first region 1A and the second region 1B are respectively arranged in the epiphysis The inner surfaces of X1 and the bone X2 make the bone fixation plate 1 abut the guide pin P at the recess 6, thereby positioning the bone fixation plate 1 on the epiphysis X1 and the bone X2. The position of the guide pin P with respect to the epiphysis X1 is set so that the first thin-layer region 4 is arranged on the pivot H. In this state, the difference between the shape of the bone fixing plate 1 and the shape of the tibia X is confirmed.

其次，藉著使骨固定板1於第一薄層區域4及第二薄層區域5中彎曲，來進行調整，使得骨固定板1的形狀配合脛骨X的內側表面的形狀。關於骨固定板1的彎曲處理，可使用例如專用的彎曲器。 然後，再次地，分別將第一區域1A及第二區域1B配置到骨骺X及骨幹X2的內側表面，並且藉著使骨固定板1於凹部6處抵靠導銷P，以進行骨固定板1相對於骨骺X1及骨幹X2的定位處理。Secondly, by bending the bone fixation plate 1 in the first thin-layer area 4 and the second thin-layer area 5, adjustment is performed so that the shape of the bone fixation plate 1 matches the shape of the inner surface of the tibia X. Regarding the bending process of the bone fixation plate 1, for example, a dedicated bender can be used. Then, again, the first area 1A and the second area 1B are respectively arranged on the inner surface of the epiphysis X and the bone shaft X2, and the bone fixation plate 1 is pressed against the guide pin P at the recess 6 to perform the bone fixation plate 1 Positioning relative to the epiphysis X1 and backbone X2.

接下來，將螺釘S經由第一區域1A的插入孔2內螺入骨骺X1，將螺釘S經由第二區域1B的插入孔2內螺入骨幹X2。各螺釘S被螺入至骨骺X1、骨幹X2直到頭部緊固於插入孔2內。藉著於樞轉部H的上下兩側的固定於骨骺X1及骨幹X2的骨固定板1，使得骨骺X1相對於骨幹X2以樞轉部H為軸所作擺動受到限制，並使骨骺X1相對於骨幹X2的位置穩定。Next, the screw S is screwed into the epiphysis X1 through the insertion hole 2 of the first area 1A, and the screw S is screwed into the bone X2 through the insertion hole 2 of the second area 1B. Each screw S is screwed into the epiphysis X1 and the bone shaft X2 until the head is fastened in the insertion hole 2. With the bone fixation plates 1 fixed to the epiphysis X1 and the bone X2 on the upper and lower sides of the pivoting portion H, the swing of the epiphysis X1 relative to the bone X2 about the pivot H as the axis is restricted, and the epiphysis X1 is relatively The position of backbone X2 is stable.

接著，將楔形的人造骨C插入至擴張的切割面Y之間的縫隙中，並且以跨越切割面之方式配置另一個骨固定板30於骨骺X1及骨幹X2的外側面，並將此骨固定板30以螺釘S固定於骨骺X1及骨幹X2。Next, insert the wedge-shaped artificial bone C into the gap between the expanded cutting surface Y, and place another bone fixation plate 30 on the outer surface of the epiphysis X1 and the diaphysis X2 so as to cross the cutting surface, and fix the bone The plate 30 is fixed to the epiphysis X1 and the bone shaft X2 with screws S.

為了獲得對骨固定板1的高固定力，必須於螺釘S的頭部與插入孔2之間具有高固定力。為此，插入孔2的邊緣部3必須具有高強度。此外，由於插入孔2的變形及損傷會導致螺釘S與插入孔2之間固定力降低，因此必須防止插入孔2的變形及損傷。In order to obtain a high fixing force to the bone fixing plate 1, it is necessary to have a high fixing force between the head of the screw S and the insertion hole 2. For this reason, the edge portion 3 of the insertion hole 2 must have high strength. In addition, since the deformation and damage of the insertion hole 2 will reduce the fixing force between the screw S and the insertion hole 2, it is necessary to prevent the deformation and damage of the insertion hole 2.

本實施型態之骨固定板1當中，於長度方向的複數處設置有比邊緣部3還要薄，剛性比邊緣部3低的薄層區域4, 5。因此能夠在防止插入孔2變形的同時，還可以選擇性地、輕易地將固定板1於薄層區域處4, 5作變形處理。據此，可在不影響骨固定板1對於骨頭的固定力情形下，容易地調整骨固定板1的形狀。In the bone fixation plate 1 of this embodiment, thin layer regions 4 and 5 that are thinner than the edge portion 3 and have lower rigidity than the edge portion 3 are provided at plural positions in the longitudinal direction. Therefore, while preventing the deformation of the insertion hole 2, it is also possible to selectively and easily deform the fixing plate 1 at the thin layer area 4, 5. Accordingly, the shape of the bone fixing plate 1 can be easily adjusted without affecting the fixing force of the bone fixing plate 1 to the bone.

此外，於配置於樞轉部H的第一區域1A與第二區域1B之間的部分中不需要插入孔2。於此部分中可藉著設置具一致的橫向剖面的長條第一薄層區域4，達到具效果性地提升骨固定板1的變形自由度。也就是說，可容易地將第一薄層區域4於長度方向的任意位置上彎曲、扭曲成任意形狀。因此，也就可以容易地隨著患者的骨頭形狀來調整骨固定板1。In addition, the insertion hole 2 is not required in the portion disposed between the first area 1A and the second area 1B of the pivot portion H. In this part, a long first thin-layer region 4 with a uniform transverse cross-section can be provided to effectively improve the deformation freedom of the bone fixation plate 1. That is, the first thin layer region 4 can be easily bent and twisted into any shape at any position in the length direction. Therefore, the bone fixing plate 1 can be easily adjusted according to the bone shape of the patient.

此外，藉著於內側表面7形成溝槽9，可使得骨固定板1於寬度方向的2點上接觸骨X，以確保骨X的表面與溝槽9內表面之間的縫隙。據此，可減少與內側表面7與骨X之間的接觸面積，並降低骨固定板1所造成對於骨X表面血管之影響，且同時還能穩定骨固定板1相對於骨X的位置及姿態。 此外，可利用形成於骨固定板1一端的凹部6及導銷P，簡單地進行骨固定板1相對於骨X的定位。In addition, by forming the groove 9 on the inner surface 7, the bone fixation plate 1 can contact the bone X at two points in the width direction to ensure a gap between the surface of the bone X and the inner surface of the groove 9. Accordingly, the contact area between the inner surface 7 and the bone X can be reduced, and the influence of the bone fixation plate 1 on the blood vessels on the surface of the bone X can be reduced, and at the same time, the position of the bone fixation plate 1 relative to the bone X can be stabilized. attitude. In addition, the recess 6 and the guide pin P formed at one end of the bone fixation plate 1 can be used to easily position the bone fixation plate 1 with respect to the bone X.

此外，作為螺釘S，可藉著使用與插入孔2緊固的鎖定螺釘，以防止以螺釘S將骨固定板1固定於骨X之後，螺釘S往從骨X中掉出之方向移動，並維持骨固定板1對於骨X的固定力。 此外，配置於骨骺X1的第一區域1A的2個插入孔2係於寬度方向上排列。據此，可在將第一區域1A長度減少至與邊緣部3寬度同等程度的同時，並使用2根螺釘來將第一區域1A堅固地固定在骨骺X1。如此的短狀第一區域1A特別適合適用至短的骨骺X1。In addition, as the screw S, a locking screw fastened to the insertion hole 2 can be used to prevent the screw S from moving in the direction of falling out of the bone X after the bone fixing plate 1 is fixed to the bone X with the screw S, and The fixation force of the bone fixation plate 1 on the bone X is maintained. In addition, the two insertion holes 2 arranged in the first region 1A of the epiphysis X1 are aligned in the width direction. According to this, while reducing the length of the first region 1A to the same extent as the width of the edge portion 3, the first region 1A can be firmly fixed to the epiphysis X1 by using two screws. Such a short first region 1A is particularly suitable for the short epiphysis X1.

於上述實施型態當中已針對T字形骨固定板1進行說明，但骨固定板1的形狀可作適當變更。圖7及圖8係表示骨固定板1的變形例。 圖7的骨固定板10於厚度方向觀察的俯視圖中呈Y字形。具體來說，第一區域10A呈V字形，具有相對於縱軸A傾斜的2個部分，且比第二區域10B還要往寬度方向的兩側突出。第二區域10B與第二區域1B為相同構成。第一區域10A的2個插入孔2係於寬度方向上往相反方向偏離縱軸A。於第一區域1A的各插入孔2與第一薄層區域4之間，設置有與第二薄層區域5相同的薄層區域51。In the above embodiments, the T-shaped bone fixation plate 1 has been described, but the shape of the bone fixation plate 1 can be appropriately changed. FIGS. 7 and 8 show modified examples of the bone fixation plate 1. The bone fixation plate 10 of FIG. 7 has a Y-shape in a plan view viewed in the thickness direction. Specifically, the first region 10A has a V-shape, has two portions inclined with respect to the longitudinal axis A, and protrudes on both sides in the width direction than the second region 10B. The second area 10B and the second area 1B have the same configuration. The two insertion holes 2 of the first region 10A are offset from the longitudinal axis A in the opposite direction in the width direction. Between each insertion hole 2 of the first region 1A and the first thin layer region 4, the same thin layer region 51 as the second thin layer region 5 is provided.

圖8的骨固定板20由厚度方向觀察的俯視圖中呈I字形。具體地說，第一區域20A及第二區域20B沿著縱軸A直線狀延伸，第一區域20A及第二區域20B的所有插入孔2係沿著縱軸A而排列為一列。第一區域20A的2個插入孔2之間設置有與第二薄層區域5相同的薄層區域52。 骨固定板10, 20亦具有：形成於一端的側面的凹部6；以及形成於內側表面7的溝槽9。The bone fixation plate 20 of FIG. 8 has an I-shape in a plan view viewed from the thickness direction. Specifically, the first area 20A and the second area 20B extend linearly along the longitudinal axis A, and all the insertion holes 2 of the first area 20A and the second area 20B are arranged in a row along the longitudinal axis A. A thin layer region 52 identical to the second thin layer region 5 is provided between the two insertion holes 2 of the first region 20A. The bone fixation plates 10 and 20 also have: a recess 6 formed on the side surface of one end; and a groove 9 formed on the inner surface 7.

此外，上述HTO僅為骨固定板1, 10, 20使用方法的一例，骨固定板1, 10, 20可使用於其他部位及其他用途。可根據適用部位及用途，來變更骨固定板1, 10, 20的形狀及尺寸及插入孔2的數量。In addition, the above-mentioned HTO is only an example of how to use the bone fixation plates 1, 10, and 20, and the bone fixation plates 1, 10, and 20 can be used for other parts and other purposes. The shape and size of the bone fixation plates 1, 10, 20 and the number of insertion holes 2 can be changed according to the applicable part and purpose.

舉例來說，骨固定板1, 10, 20可與其他骨固定板30同樣地固定至脛骨X的外側表面。或者，骨固定板1, 10, 20亦可適用於大腿骨或是鎖骨等其他部位的骨頭。 骨固定板1, 10, 20亦可使用於任意部位骨頭之骨折治療。 亦可根據適用部位以及用途，將第一薄層區域4的長度設置為小於第二薄層區域5的長度。 此外，雖然於圖1及圖7當中，第一區域1A, 10A的2個插入孔2往寬度方向上的兩側偏離縱軸A，但第一區域的插入孔2之配置並不限定於此，亦可為第一區域的插入孔2的一部分或是全部於寬度方向往兩側或是一側偏離縱軸A。亦可根據第一區域的插入孔2的配置，來變更於俯視圖中的骨固定板之概略形狀。例如，於俯視圖呈L字形的骨固定板情況中，第一區域的插入孔2係往寬度方向上的一側偏離縱軸A。For example, the bone fixation plates 1, 10, 20 can be fixed to the outer surface of the tibia X in the same way as the other bone fixation plates 30. Alternatively, the bone fixation plates 1, 10, 20 can also be applied to bones in other parts such as the femur or the clavicle. Bone fixation plates 1, 10, 20 can also be used to treat bone fractures in any part. It is also possible to set the length of the first thin-layer region 4 to be smaller than the length of the second thin-layer region 5 according to the applicable location and purpose. In addition, although in FIGS. 1 and 7, the two insertion holes 2 of the first regions 1A and 10A deviate from the longitudinal axis A to both sides in the width direction, the arrangement of the insertion holes 2 of the first region is not limited to this It may also be that a part or all of the insertion hole 2 in the first region deviates from the longitudinal axis A on both sides or one side in the width direction. The general shape of the bone fixation plate in the plan view can also be changed according to the arrangement of the insertion holes 2 in the first region. For example, in the case of an L-shaped bone fixation plate in a plan view, the insertion hole 2 of the first region is offset from the longitudinal axis A to one side in the width direction.
