胫骨截骨系统及其截骨量调整装置Tibial osteotomy system and its osteotomy volume adjustment device

技术领域technical field

本发明涉及医疗器械技术领域，特别是涉及一种胫骨截骨系统及其截骨量调整装置。The invention relates to the technical field of medical devices, in particular to a tibial osteotomy system and a device for adjusting the osteotomy amount.

背景技术Background technique

单髁膝关节置换手术过程中需要对胫骨侧进行截骨，以便安装合适的胫骨假体。截骨位置的准确性将直接影响到假体安装的结果，基于此，在膝关节置换手术中，通常采取胫骨截骨量微调装置对胫骨截骨板高度进行微调，使胫骨截骨板到达最合适的截骨位置，以便对胫骨平台的精确截骨。Unicondylar knee arthroplasty requires an osteotomy on the tibial side in order to install a suitable tibial component. The accuracy of the osteotomy position will directly affect the result of the prosthesis installation. Based on this, in knee replacement surgery, the tibial osteotomy volume fine-tuning device is usually used to fine-tune the height of the tibial osteotomy plate, so that the tibial osteotomy plate can reach the highest level. Proper osteotomy location for precise osteotomy of the tibial plateau.

传统的胫骨截骨量微调装置一般为螺纹微调式或卡扣式(即齿轮式)。The traditional tibial osteotomy volume fine-tuning device is generally a thread fine-tuning type or a snap-on type (ie, a gear type).

其中，螺纹微调式是将上端杆和下端杆通过螺纹连接一起，胫骨截骨板与上端杆相连接，通过旋转螺母使上端杆相对下端杆上下移动，进而实现胫骨截骨板的微调。这种结构，在螺纹旋转过程中，容易产生磨屑而引起卡顿，或因螺纹精度问题而容易发生卡顿，而且旋转力易导致上端杆偏移，另外锁合不稳定，易松脱。Among them, the thread fine-tuning type is that the upper end rod and the lower end rod are connected together by thread, the tibial osteotomy plate is connected with the upper end rod, and the upper end rod is moved up and down relative to the lower end rod by rotating the nut, thereby realizing the fine adjustment of the tibial osteotomy plate. In this structure, during the thread rotation process, it is easy to generate wear debris and cause jamming, or it is easy to cause jamming due to the problem of thread accuracy, and the rotation force is easy to cause the upper end rod to shift, and the locking is unstable and easy to loosen.

卡扣式微调方式大多是通过控制齿条之间的啮合或松脱来控制上端杆的锁合或移动，在齿条彼此之间处于松脱时，可以移动上端杆以调整连接于上端杆的胫骨截骨板的位置，在齿条彼此之间处于啮合时，齿条锁住上端杆的位置，以固定胫骨截骨板的位置。这种结构虽然锁合稳定可靠，但调节连续性差，无法满足对胫骨截骨板的位置的精准调节。Most of the snap-on fine-tuning methods control the locking or movement of the upper end rod by controlling the meshing or loosening between the racks. When the racks are loose from each other, the upper end rod can be moved to adjust the The position of the tibial osteotomy plate, when the racks are engaged with each other, the rack locks the position of the upper end rod to fix the position of the tibial osteotomy plate. Although this structure has stable and reliable locking, it has poor adjustment continuity and cannot meet the precise adjustment of the position of the tibial osteotomy plate.

结合图1所示，本发明提供的一种截骨量调整装置10，用于安装在胫骨截骨系统中，调整截骨的位置，从而满足对胫骨B平台精确截骨需要。Referring to Fig. 1, the present invention provides an osteotomyvolume adjustment device 10, which is used to be installed in a tibial osteotomy system to adjust the position of the osteotomy, so as to meet the needs of precise osteotomy of the tibial B platform.

在一实施例中，截骨量调整装置10包括第一杆件1和第二杆件2。通过调整第一杆件1和第二杆件2的相对位置，改变第一杆件1和第二杆件2的整体长度，从而适应截骨高度的需要。In one embodiment, the osteotomyamount adjustment device 10 includes afirst rod 1 and asecond rod 2 . By adjusting the relative positions of thefirst rod 1 and thesecond rod 2, the overall length of thefirst rod 1 and thesecond rod 2 is changed, so as to meet the needs of the osteotomy height.

例如，结合图2和图3所示，在本发明提供一种胫骨截骨系统中，截骨量调整装置10的第一杆件1和第二杆件2分别连接截骨导板20和抱踝器30。在使用胫骨截骨系统时，抱踝器30夹持固定在患者下肢(胫骨B)的靠近踝关节B2位置处，从而在截骨量调整装置10调整第一杆件1和第二杆件2的相对位置后，使得截骨导板20相对抱踝器30升降移动，由于抱踝器30被固定在胫骨B上，从而通过截骨量调整装置10调整截骨导板20的位置时，截骨导板20能够相对胫骨B移动，最终使得截骨导板20处于邻近胫骨B的关节面B1下方比较合适的距离处，这样截骨导板20的截骨槽21便能够引导截骨刀具对需要截骨的位置进行截骨。For example, as shown in FIG. 2 and FIG. 3 , in a tibial osteotomy system provided by the present invention, thefirst rod 1 and thesecond rod 2 of the osteotomyvolume adjustment device 10 are respectively connected to theosteotomy guide 20 and theankle hugging device 30. When using the tibial osteotomy system, theankle holder 30 is clamped and fixed at the position of the patient's lower limb (tibia B) near the ankle joint B2, so as to adjust thefirst rod 1 and thesecond rod 2 in the osteotomyamount adjustment device 10 After the relative position of theosteotomy guide plate 20 is moved up and down relative to theankle holder 30, since theankle holder 30 is fixed on the tibia B, when the position of theosteotomy guide plate 20 is adjusted by the osteotomyamount adjustment device 10, theosteotomy guide plate 20 can move relative to the tibia B, and finally make theosteotomy guide 20 at a suitable distance below the articular surface B1 adjacent to the tibia B, so that theosteotomy groove 21 of theosteotomy guide 20 can guide the osteotomy tool to the position that needs to be cut. Perform osteotomy.

需要说明的是，结合图2至图4所示，以胫骨B作为参考，截骨导板20作为引导截骨刀具对胫骨B进行截骨操作的结构件，截骨槽21贯穿截骨导板20相对的两个侧面(前后两侧)，从而在截骨导板20安装至胫骨B的截骨位置处时，截骨刀具能够穿过截骨槽21对胫骨B进行截骨操作。It should be noted that, with reference to the tibia B as shown in FIG. 2 to FIG. 4 , theosteotomy guide 20 is used as a structural component for guiding the osteotomy tool to perform the osteotomy operation on the tibia B, and theosteotomy groove 21 penetrates through theosteotomy guide 20 to face each other. so that when theosteotomy guide 20 is installed at the osteotomy position of the tibia B, the osteotomy tool can pass through theosteotomy slot 21 to perform the osteotomy operation on the tibia B.

由于截骨量调整装置10是通过调整第一杆件1和第二杆件2的彼此相对位置，以使得截骨导板20相对抱踝器30移动至需要截骨的位置处，因此，第一杆件1和第二杆件2中的一个与截骨导板20相连接，另一个与抱踝器30相连接即可。Because the osteotomyvolume adjusting device 10 adjusts the relative positions of thefirst rod 1 and thesecond rod 2 to each other, so that theosteotomy guide 20 moves relative to theankle holder 30 to the position where the osteotomy is required, therefore, the first One of therod member 1 and thesecond rod member 2 can be connected with theosteotomy guide 20 , and the other can be connected with theankle brace 30 .

如图2和图3所示，截骨导板20与第一杆件1的远离第二杆件2的一端相连接，抱踝器30与第二杆件2的远离第一杆件1的一端相连接。As shown in FIGS. 2 and 3 , theosteotomy guide 20 is connected with the end of thefirst rod 1 away from thesecond rod 2 , and theankle brace 30 is connected with the end of thesecond rod 2 away from thefirst rod 1 connected.

在一些实施方式中，抱踝器30与第二杆件2之间可以是通过横杆40相连接，以便利用横杆40将截骨量调整装置10保持在距离胫骨B一定距离处，截骨导板20便可以安装在距离胫骨B比较合适的距离处，以适应截骨需要。In some embodiments, theankle brace 30 and thesecond rod 2 may be connected by across bar 40, so that the osteotomyvolume adjusting device 10 can be kept at a certain distance from the tibia B by thecross bar 40, and the osteotomy Theguide plate 20 can be installed at a suitable distance from the tibia B to meet the needs of osteotomy.

第二杆件2与横杆40之间可以采取活动连接，在调整好两者的相对位置后，通过紧固件或锁紧结构锁定两者的相对位置，以确保对胫骨B进行截骨操作时，整个胫骨截骨系统的稳定性。在一些实施方式中，横杆40与第二杆件2为一体结构，即，横杆40与第二杆件2为一个结构件，两种通过一体成型的方式结合于一体，从而减少零部件数量及装配环节。An active connection can be adopted between thesecond rod 2 and thecross rod 40. After the relative positions of the two are adjusted, the relative positions of the two are locked by a fastener or a locking structure, so as to ensure the osteotomy of the tibia B. , the stability of the entire tibial osteotomy system. In some embodiments, thecross bar 40 and thesecond bar 2 are integral structures, that is, thecross bar 40 and thesecond bar 2 are one structure, and the two are integrated into one body by integral molding, thereby reducing the number of parts and components. quantity and assembly.

结合图1和图5所示，第一杆件1开设有第一导槽1c，第一导槽1c大致沿第一杆件1的长度方向延伸。第二杆件2插设于第一杆件1中，具体地，第一杆件1开设有插接腔1a，第一导槽1c贯穿插接腔1a的侧壁，以与插接腔1a相连通，第二杆件2可伸缩移动地插设于插接腔1a，继而第二杆件2能够稳定地沿插接腔1a相对第一杆件1移动，以调整截骨导板20的位置。With reference to FIGS. 1 and 5 , thefirst rod member 1 is provided with afirst guide groove 1 c , and thefirst guide groove 1 c extends substantially along the length direction of thefirst rod member 1 . Thesecond rod member 2 is inserted into thefirst rod member 1. Specifically, thefirst rod member 1 is provided with a plug-in cavity 1a, and thefirst guide groove 1c penetrates through the side wall of the plug-in cavity 1a to communicate with the plug-in cavity 1a. Thesecond rod 2 is telescopically inserted into the insertion cavity 1a, and then thesecond rod 2 can stably move relative to thefirst rod 1 along the insertion cavity 1a to adjust the position of theosteotomy guide 20 .

需要说明的是，第一杆件1和第二杆件2之间也可以不采取插接的配合方式相连接，例如，在一些实施方式中，第一杆件1和第二杆件2之间可滑动低叠设在一起，并被配置为：当第一杆件1和第二杆件2相对滑动时，第一杆件1和第二杆件2的整体长度发生改变。从而通过这种结构形式，也能够通过调整第一杆件1和第二杆件2在长度方向上的相对位置，满足对截骨导板20的位置调整需要，从而使得截骨导板20能够被调整至合适高度进行截骨。第二杆件2上连接有第一轴6，第一轴6插设于第一导槽1c，且能够沿第一导槽1c移动。It should be noted that, thefirst rod member 1 and thesecond rod member 2 may not be connected by means of plugging. For example, in some embodiments, thefirst rod member 1 and thesecond rod member 2 They are slidably stacked together and configured so that when thefirst rod 1 and thesecond rod 2 slide relative to each other, the overall length of thefirst rod 1 and thesecond rod 2 changes. Therefore, through this structure, the relative position of thefirst rod 1 and thesecond rod 2 in the length direction can also be adjusted to meet the position adjustment needs of theosteotomy guide plate 20, so that theosteotomy guide plate 20 can be adjusted. Osteotomy is performed to the appropriate height. Afirst shaft 6 is connected to thesecond rod 2 , and thefirst shaft 6 is inserted into thefirst guide groove 1c and can move along thefirst guide groove 1c.

第一轴6可以是通过焊接或螺纹连接的方式与第二杆件2相连接。在一些实施方式中，第一轴6可以是插接固定于第二杆件2，例如，结合图6所示，第二杆件2上开设有插孔2c，第一轴6插接于插孔2c，以实现第一轴6与第二杆件2的连接。第一轴6也可以是与第二杆件2一体成型的。Thefirst shaft 6 may be connected with thesecond rod member 2 by welding or screwing. In some embodiments, thefirst shaft 6 may be plugged and fixed to thesecond rod member 2. For example, as shown in FIG. 6, thesecond rod member 2 is provided with asocket 2c, and thefirst shaft 6 is plugged into the plug Thehole 2c is used to realize the connection between thefirst shaft 6 and thesecond rod 2 . Thefirst shaft 6 can also be integrally formed with thesecond rod 2 .

由于第一轴6插设于第一导槽1c并且能够沿第一导槽1c移动，而第一导槽1c大致沿第一杆件1的长度方向延伸，从而第一轴6沿第一导槽1c移动时，与第一轴6相连接的第二杆件2将与第一杆件1彼此相对移动，从而第一杆件1和第二杆件2的结合后的长度将会得到适应性调整，这样分别与第一杆件1和第二杆件2相连接的截骨导板20和抱踝器30之间的距离能够被调整至合适状态，进而截骨导板20的位置进行调整，以适应截骨需要。Since thefirst shaft 6 is inserted into thefirst guide groove 1c and can move along thefirst guide groove 1c, and thefirst guide groove 1c extends substantially along the length direction of thefirst rod 1, thefirst shaft 6 moves along thefirst guide groove 1c. When theslot 1c moves, thesecond rod 2 connected with thefirst shaft 6 will move relative to thefirst rod 1, so that the combined length of thefirst rod 1 and thesecond rod 2 will be adapted In this way, the distance between theosteotomy guide 20 and theankle holder 30 connected with thefirst rod 1 and thesecond rod 2 can be adjusted to an appropriate state, and then the position of theosteotomy guide 20 can be adjusted. to meet the needs of osteotomy.

继续参阅图1所示，截骨量调整装置10包括调节件3，调节件3通过第一轴6与第二杆件2转动连接。具体地，由于第一轴6插设于第一导槽1c，从而第一轴6的部分结构凸出于第一杆件1的表面。结合图7所示，调节件3上开设有与第一轴6相配合的轴孔3c，第一轴6凸出于第一杆件1的表面的部分结构与轴孔3c相配合。Continuing to refer to FIG. 1 , the osteotomyamount adjusting device 10 includes an adjustingmember 3 , and the adjustingmember 3 is rotatably connected with thesecond rod member 2 through thefirst shaft 6 . Specifically, since thefirst shaft 6 is inserted into thefirst guide groove 1 c , part of the structure of thefirst shaft 6 protrudes from the surface of thefirst rod 1 . Referring to FIG. 7 , the adjustingmember 3 is provided with ashaft hole 3c which is matched with thefirst shaft 6 , and the partial structure of thefirst shaft 6 protruding from the surface of thefirst rod member 1 is matched with theshaft hole 3c.

调节件3与第一轴6之间可相对转动，或者，第一轴6与第二杆件2之间可相对转动，只要调节件3通过第一轴6与第二杆件2相连接后，调节件3能够相对第二杆件2转动即可，例如，在一些实施例中，第一轴6与调节件3之间以及第一轴6与第二杆件2之间均为转动连接。Theadjustment member 3 and thefirst shaft 6 can be rotated relative to each other, or thefirst shaft 6 and thesecond rod member 2 can be rotated relative to each other, as long as theadjustment member 3 is connected to thesecond rod member 2 through thefirst shaft 6 Theadjustment member 3 can rotate relative to thesecond rod member 2. For example, in some embodiments, thefirst shaft 6 and theadjustment member 3 and thefirst shaft 6 and thesecond rod member 2 are both rotationally connected .

结合图1和图7所示，调节件3上开设有第二导槽3b，第一杆件1设有第二轴7。第二轴7可以是通过插接的方式与第一杆件1相固定，例如，第一杆件1靠近端部位置处设有销孔1b，第二轴7与销孔1b插接配合，以固定在第一杆件1上。在其他实施方式中，第二轴7与第一杆件1螺纹连接、卡接、焊接或一体成型。对于第二轴7与第一杆件1之间的连接方式，在此不做限定。As shown in FIG. 1 and FIG. 7 , the adjustingmember 3 is provided with asecond guide groove 3 b , and thefirst rod member 1 is provided with asecond shaft 7 . Thesecond shaft 7 can be fixed to thefirst rod 1 by means of plugging. For example, thefirst rod 1 is provided with a pin hole 1b near the end, and thesecond shaft 7 is inserted and matched with the pin hole 1b. to be fixed on thefirst rod 1. In other embodiments, thesecond shaft 7 and thefirst rod member 1 are screwed, clamped, welded or integrally formed. The connection mode between thesecond shaft 7 and thefirst rod member 1 is not limited here.

以第一轴6与调节件3的交点(即轴孔3c)为圆心，第二导槽3b在各弧度上的半径不同，即第二导槽3b在各弧度上的点到轴孔3c的距离不同，优选为逐步增大或逐步减小。第二轴7插设于第二导槽3b，当调节件3绕第一轴6相对第一杆件1转动时，第二轴7沿第二导槽3b移动并靠近或远离第一轴6，以调整第一杆件1与第二杆件2在轴向上的相对位置，此处轴向是指沿第一杆件1或第二杆件2的长度方向。本文中的第一轴6沿第一导槽1c移动以及第二轴7沿第二导槽3b移动均是指相对移动，即相对移动的两方中的任意一方移动，而另一方静止，也可以是两方均移动。Taking the intersection of thefirst shaft 6 and the adjusting member 3 (ie, theshaft hole 3c) as the center of the circle, the radius of thesecond guide groove 3b on each radian is different, that is, the point of thesecond guide groove 3b on each radian to theshaft hole 3c. The distances are different, preferably gradually increasing or decreasing. Thesecond shaft 7 is inserted into thesecond guide groove 3b. When the adjustingmember 3 rotates relative to thefirst rod member 1 around thefirst shaft 6, thesecond shaft 7 moves along thesecond guide groove 3b and approaches or moves away from thefirst shaft 6 , to adjust the relative position of thefirst rod 1 and thesecond rod 2 in the axial direction, where the axial direction refers to the length direction of thefirst rod 1 or thesecond rod 2 . The movement of thefirst shaft 6 along thefirst guide groove 1c and the movement of thesecond shaft 7 along thesecond guide groove 3b herein both refer to relative movement, that is, either one of the two relative moving sides moves while the other is stationary, and Both parties can move.

需要说明的是，第二导槽3b可以是通槽，即贯穿调节件3的外表面。第二导槽3b也可以是盲槽，即不贯穿调节件3的外表面。It should be noted that, thesecond guide groove 3b may be a through groove, that is, penetrate through the outer surface of the adjustingmember 3 . Thesecond guide groove 3b may also be a blind groove, that is, it does not penetrate through the outer surface of the adjustingmember 3 .

该实施例中，利用调节件3上的第二导槽3b对第二轴7的约束，使得第二轴7沿第二导槽3b移动时，靠近或远离第一轴6，即第一轴6和第二轴7之间的距离得以调整，第二轴7设置于第一杆件1，从而第一轴6和第二轴7之间的距离变化时，第一轴6沿第一导槽1c移动，这样与第一轴6相连接的第二杆件2将相对第一杆件1移动，从而达到调整第一杆件1和第二杆件2在第一杆件1的长度方向上的相对位置，进而与第一杆件1相连接的截骨导板20相对第二杆件2上移或下移，实现截骨导板20位置调整的目的。第二轴7沿第二导槽3b移动时相对第一轴6的位置变化量是连续的，也即，第一轴6和第二轴7之间的距离能够被精确的控制，从而通过这种截骨量调整装置10调整截骨导板20相对胫骨B的截骨位置时，能够获得精确微调的效果。In this embodiment, thesecond shaft 7 is restrained by thesecond guide groove 3b on the adjustingmember 3, so that when thesecond shaft 7 moves along thesecond guide groove 3b, it approaches or moves away from thefirst shaft 6, that is, the first shaft The distance between thefirst shaft 6 and thesecond shaft 7 is adjusted, and thesecond shaft 7 is arranged on thefirst rod 1, so that when the distance between thefirst shaft 6 and thesecond shaft 7 changes, thefirst shaft 6 moves along the first guide. Thegroove 1c moves, so that thesecond rod 2 connected with thefirst shaft 6 will move relative to thefirst rod 1, so as to adjust the length direction of thefirst rod 1 and thesecond rod 2 in thefirst rod 1 Then, theosteotomy guide plate 20 connected with thefirst rod member 1 moves up or down relative to thesecond rod member 2 to achieve the purpose of adjusting the position of theosteotomy guide plate 20 . When thesecond shaft 7 moves along thesecond guide groove 3b, the positional change relative to thefirst shaft 6 is continuous, that is, the distance between thefirst shaft 6 and thesecond shaft 7 can be precisely controlled, so that through this When the osteotomyvolume adjusting device 10 adjusts the osteotomy position of theosteotomy guide plate 20 relative to the tibia B, the effect of precise fine adjustment can be obtained.

第二导槽3b可以是圆弧槽。例如，在一些实施方式中，结合图8所示，第二导槽3b为圆弧槽时，第二导槽3b在沿其中线方向上具有相对的第一端部3b1和第二端部3b2，第一端部3b1与第一轴6之间的距离r1为50mm，第二端部3b2到第一轴6之间的距离r2为10mm，r1和r2可取其他数值，只要二者不相等即可。结合图1所示，随着调节件3相对第二杆件2绕第一轴6的轴线转动，在第二轴7沿第二导槽3b由第一端部3b1朝第二端部3b2移动的过程中，第二轴7与第一轴6之间的相对距离逐渐缩小，由于第二轴7与第一杆件1之间的位置固定，从而第一轴6将沿第一导槽1c移动。由于第一轴6与第二杆件2之间的位置固定，从而随着第二轴7与第一轴6之间的相对距离逐渐缩小，第二杆件2与第一杆件1之间相对滑动，达到调整截骨导板20位置的需要。Thesecond guide groove 3b may be a circular arc groove. For example, in some embodiments, as shown in FIG. 8 , when thesecond guide groove 3b is a circular arc groove, thesecond guide groove 3b has an opposite first end 3b1 and a second end 3b2 along the centerline direction , the distance r1 between the first end 3b1 and thefirst shaft 6 is 50mm, the distance r2 between the second end 3b2 and thefirst shaft 6 is 10mm, r1 and r2 can take other values, as long as they are not equal Can. 1, as the adjustingmember 3 rotates relative to thesecond rod member 2 around the axis of thefirst shaft 6, thesecond shaft 7 moves along thesecond guide groove 3b from the first end 3b1 to the second end 3b2 During the process, the relative distance between thesecond shaft 7 and thefirst shaft 6 is gradually reduced. Since the position between thesecond shaft 7 and thefirst rod 1 is fixed, thefirst shaft 6 will follow thefirst guide groove 1c move. Since the position between thefirst shaft 6 and thesecond rod member 2 is fixed, as the relative distance between thesecond shaft 7 and thefirst shaft 6 gradually decreases, the distance between thesecond rod member 2 and thefirst rod member 1 is gradually reduced. Relative sliding, to meet the needs of adjusting the position of theosteotomy guide 20 .

在一些实施方式中，结合图8所示，在第二轴7与第二导槽3b的配合限位下，调节件3绕第一轴6的转动幅度β为10°～90°。In some embodiments, as shown in FIG. 8 , under the cooperating limit of thesecond shaft 7 and thesecond guide groove 3 b , the rotation range β of the adjustingmember 3 around thefirst shaft 6 is 10°˜90°.

需要说明的是，调节件3绕第一轴6的转动幅度β是指，通过驱使调节件3绕第一轴6转动使得第二轴7沿第二导槽3b的第一端部3b1运动到第二端部3b2时，调节件3转动的角度。It should be noted that the rotation amplitude β of the adjustingmember 3 around thefirst shaft 6 refers to that by driving the adjustingmember 3 to rotate around thefirst shaft 6, thesecond shaft 7 moves along the first end 3b1 of thesecond guide groove 3b to When the second end portion 3b2 is used, the rotation angle of the adjustingmember 3.

该实施例中，将调节件3绕第一轴6的转动幅度β控制在10°～90°，能够确保调节件3对第一轴6和第二轴7的相对位置进行调整时，具有足够大的调节行程，以便通过对第一轴6和第二轴7之间相对位置的调整，精确地调整第一杆件1和第二杆件2的相对位置，以适应截骨导板20的位置能够在比较大的范围内精确地移动，提高对截骨量的精准控制。如果转动幅度β小于10°，则第二导槽3b的倾斜过于陡峭，转动调节件3时，对第一轴6和第二轴7之间相对位置的调整变化过快，不利于对截骨量的精确控制。如果转动幅度β大于90°，则调节件3体积太大，不利于整个装置体积的紧凑性。In this embodiment, the rotation range β of the adjustingmember 3 around thefirst shaft 6 is controlled to be 10°˜90°, which can ensure that the adjustingmember 3 has sufficient power when adjusting the relative positions of thefirst shaft 6 and thesecond shaft 7 . Large adjustment stroke, so that by adjusting the relative position between thefirst shaft 6 and thesecond shaft 7, the relative position of thefirst rod 1 and thesecond rod 2 can be accurately adjusted to suit the position of theosteotomy guide 20 It can move accurately in a relatively large range and improve the precise control of the amount of osteotomy. If the rotation amplitude β is less than 10°, the inclination of thesecond guide groove 3b is too steep, and when the adjustingmember 3 is rotated, the adjustment of the relative position between thefirst shaft 6 and thesecond shaft 7 changes too quickly, which is not conducive to the osteotomy. precise control of the amount. If the rotation amplitude β is greater than 90°, the volume of the adjustingmember 3 is too large, which is not conducive to the compactness of the entire device volume.

再次参阅图1所示，截骨量调整装置10包括止动件4，止动件4能够沿第二杆件2的长度方向移动至与调节件3相抵持，以限制调节件3绕第一轴6转动，且止动件4能够沿第二杆件2的长度方向移动离开调节件3，以解除对调节件3的抵持限位。Referring to FIG. 1 again, the osteotomyamount adjustment device 10 includes astopper 4, which can move along the length direction of thesecond rod 2 to abut against theadjustment piece 3, so as to limit theadjustment piece 3 from wrapping around thefirst rod 2. Theshaft 6 rotates, and thestopper 4 can move away from the adjustingmember 3 along the length direction of thesecond rod member 2 to release the abutting limit on the adjustingmember 3 .

该实施例中，利用止动件4能够锁定好调节件3的位置，从而使得调节件3保持第一轴6和第二轴7的相对位置，进而使得第一杆件1和第二杆件2彼此相固定，以稳定地支撑截骨导板20。在需要对截骨导板20的位置进行调整时，只需要移开止动件4，使得止动件4解除对调节件3的位置锁定，便可以利用调节件3绕第一轴6的轴线转动来调整第一杆件1和第二杆件2的相对位置。In this embodiment, thestopper 4 can be used to lock the position of the adjustingmember 3, so that the adjustingmember 3 maintains the relative position of thefirst shaft 6 and thesecond shaft 7, thereby making thefirst rod 1 and thesecond rod 2 are fixed to each other to support theosteotomy guide 20 stably. When the position of theosteotomy guide 20 needs to be adjusted, it is only necessary to remove thestopper 4 so that thestopper 4 unlocks the position of theadjustment member 3, and theadjustment member 3 can be used to rotate around the axis of thefirst shaft 6 to adjust the relative position of thefirst rod 1 and thesecond rod 2.

结合图1、图7和图9所示，调节件3设有齿状边缘3a，止动件4包括主体部4b和位于主体部4b的锁止齿4a，当止动件4沿第二杆件2的长度方向移动至于调节件3相抵持时，锁止齿4a与齿状边缘3a相配合，从而锁定调节件3的位置，使得调节件3不能绕第一轴6相对第二杆件2转动，此时第一轴6和第二轴7的相对位置被锁定，以固定截骨导板20的位置。在需要调整截骨导板20的位置时，只需要将止动件4沿第二杆件2的长度方向移动离开调节件3，以解除述锁止齿4a与齿状边缘3a的配合即可。1, 7 and 9, the adjustingmember 3 is provided with atoothed edge 3a, and thestopper 4 includes amain body portion 4b and a lockingtooth 4a located in themain body portion 4b. When the length direction of themember 2 moves, when the adjustingmember 3 abuts against each other, the lockingteeth 4a cooperate with thetoothed edge 3a, thereby locking the position of the adjustingmember 3, so that the adjustingmember 3 cannot be relative to thesecond rod member 2 around thefirst axis 6 When rotated, the relative positions of thefirst shaft 6 and thesecond shaft 7 are locked to fix the position of theosteotomy guide 20 . When the position of theosteotomy guide plate 20 needs to be adjusted, it is only necessary to move thestopper 4 away from theadjustment element 3 along the length direction of thesecond rod 2 to release the engagement between the lockingteeth 4a and thetoothed edge 3a.

齿状边缘3a的啮合齿沿第一轴6的周向呈圆弧形排布，这样无论调节件3绕第一轴6的轴线转动至何种位置，锁止齿4a均能够与相应的啮合齿稳定啮合，以提高对调节件3的位置的锁定稳定性。The meshing teeth of thetoothed edge 3a are arranged in a circular arc along the circumferential direction of thefirst shaft 6, so that no matter what position the adjustingmember 3 rotates around the axis of thefirst shaft 6, the lockingteeth 4a can engage with the corresponding The teeth engage stably to improve the locking stability of the position of theadjustment piece 3 .

在一些实施方式中，齿状边缘3a的齿顶半径R为15mm～60mm，比如15mm、25mm、35mm、45mm、55mm或60mm。通过将齿状边缘3a的齿顶半径R控制在15mm～60mm，使得调节件3的齿状边缘3a到第一轴6的轴线的距离足够大，以便设置第二导槽3b时，可以将第二导槽3b对第二轴7相对第一轴6的移动的位移量设置的足够大，以提高截骨量的调节范围。同时，调节件3的体积也不至于过大而不利于整个装置的紧凑性。In some embodiments, the tip radius R of thetoothed edge 3a is 15mm-60mm, such as 15mm, 25mm, 35mm, 45mm, 55mm or 60mm. By controlling the tooth tip radius R of thetoothed edge 3a to be 15mm-60mm, the distance from thetoothed edge 3a of the adjustingmember 3 to the axis of thefirst shaft 6 is large enough, so that when thesecond guide groove 3b is provided, the first The displacement of thesecond shaft 7 relative to thefirst shaft 6 by the twoguide grooves 3b is set sufficiently large to improve the adjustment range of the osteotomy amount. At the same time, the volume of the adjustingmember 3 is not so large that it is not conducive to the compactness of the whole device.

结合图1和图9所示，止动件4呈环状，止动件4套设于第一杆件1或第二杆件2。Referring to FIGS. 1 and 9 , thestopper 4 is annular, and thestopper 4 is sleeved on thefirst rod 1 or thesecond rod 2 .

在一些实施方式中，截骨量调整装置10包括弹性件，如弹簧或橡胶等弹性体等等。弹性件设于第一杆件1与止动件4之间，或第二杆件2与止动件4之间，用于将止动件4弹性地抵持于调节件3。设于第一杆件1与止动件4之间是指，弹性件的一端与第一杆件1固定连接或抵接，另一端与止动件4固定连接或抵接。弹性件根据需要设为压缩状态或拉伸状态。In some embodiments, theosteotomy adjustment device 10 includes an elastic member, such as an elastic body such as a spring or rubber, and the like. The elastic piece is arranged between thefirst rod 1 and thestopper 4 , or between thesecond rod 2 and thestopper 4 , for elastically pressing thestopper 4 against theadjustment piece 3 . Disposed between thefirst rod 1 and thestopper 4 means that one end of the elastic piece is fixedly connected or abutted with thefirst rod 1 , and the other end is fixedly connected or abutted with thestopper 4 . The elastic member is set to a compressed state or a stretched state as required.

可选的，所述弹性件为弹簧5，弹簧5套设于第一杆件1或第二杆件2，并将止动件4弹性地抵持于调节件3。Optionally, the elastic member is aspring 5 , thespring 5 is sleeved on thefirst rod member 1 or thesecond rod member 2 , and elastically presses thestop member 4 against theadjustment member 3 .

第一杆件1或第二杆件2设有抵持面，例如阶梯槽或台阶面等。以第二杆件2为例，结合图6所示，第二杆件2包括两段彼此相连且径向尺寸不同的轴体2a、2b，这样，在两段轴体2a、2b的连接面形成台阶面，可选的，该台阶面朝远离轴体2a的方向凹陷，形成阶梯槽。弹簧5收容于阶梯槽，并与槽底面相抵接，这样弹簧5不会过分凸出于第二杆件2的表面，使得截骨量调整装置10的整体结构紧凑、小巧。抵持面的形式不局限于此，只要能保证弹簧5的一端能与其抵接或固定连接即可，例如也可以是设于第一杆件1或第二杆件2的凸缘，此时第一杆件1或第二杆件2不必设为粗细不同的两段。以图1为例，抵持面在止动件4左边时，弹性件设为拉伸状态；抵持面在止动件4右边时，弹性件设为压缩状态。Thefirst rod 1 or thesecond rod 2 is provided with a bearing surface, such as a stepped groove or a stepped surface. Taking thesecond rod 2 as an example, as shown in FIG. 6 , thesecond rod 2 includes twoshaft bodies 2a and 2b that are connected to each other and have different radial dimensions. A stepped surface is formed. Optionally, the stepped surface is recessed in a direction away from theshaft body 2a to form a stepped groove. Thespring 5 is accommodated in the stepped groove and abuts against the bottom surface of the groove, so that thespring 5 does not protrude too much from the surface of thesecond rod 2 , so that the overall structure of the osteotomyamount adjusting device 10 is compact and small. The form of the abutting surface is not limited to this, as long as it can ensure that one end of thespring 5 can abut or be fixedly connected to it, for example, it can also be a flange provided on thefirst rod 1 or thesecond rod 2. Thefirst rod member 1 or thesecond rod member 2 does not need to be provided in two sections with different thicknesses. Taking FIG. 1 as an example, when the abutting surface is on the left side of thestopper 4 , the elastic element is in a stretched state; when the abutting surface is on the right side of thestopper 4 , the elastic element is in a compressed state.

结合图1和图7所示，调节件3可以是镜面对称结构，形成有供第二杆件2穿过的避空位304，以便调节件3安装至第一杆件1时，第一杆件1的相对的两侧均具有相应的第二导槽3b、第二轴7等结构，使得调节件3与第一杆件1和第二杆件2之间的组装更为稳定。1 and FIG. 7 , the adjustingmember 3 may be a mirror-symmetrical structure, and aspace 304 for thesecond rod member 2 to pass through is formed, so that when the adjustingmember 3 is installed on thefirst rod member 1, the first rod member The opposite sides of the 1 have corresponding structures such as thesecond guide groove 3b, thesecond shaft 7, etc., so that the assembly between the adjustingmember 3 and thefirst rod member 1 and thesecond rod member 2 is more stable.

可以理解的是，调节件3呈镜面对称结构并不是必要的，如前述实施例中，只要调节件3能够通过第一轴6与第二杆件2转动连接，并通过设置第二导槽3b引导第二轴7滑动过程中靠近或远离第一轴6，便能够实现第一轴6与第二轴7之间相对距离的调整，以使得第一杆件1和第二杆件2沿第一杆件1的长度方向相对移动，进而调整截骨导板20的位置。It can be understood that it is not necessary for the adjustingmember 3 to have a mirror-symmetrical structure. As in the foregoing embodiment, as long as the adjustingmember 3 can be rotatably connected to thesecond rod member 2 through thefirst shaft 6, and thesecond guide groove 3b is provided by the adjustingmember 3. By guiding thesecond shaft 7 to approach or move away from thefirst shaft 6 during the sliding process, the relative distance between thefirst shaft 6 and thesecond shaft 7 can be adjusted, so that thefirst rod 1 and thesecond rod 2 can be adjusted along the The length direction of arod 1 is relatively moved, so as to adjust the position of theosteotomy guide 20 .

结合图7所示，呈镜面对称结构的调节件3，包括间隔设置的第一导片301和第二导片302，第一导片301和第二导片302之间通过两间隔设置连接臂303相连，两连接臂303与第一导片301和第二导片302围合形成避空位304，调节件3安装至第一杆件1时，第一导片301和第二导片302分别位于第一杆件1的两侧，第二杆件2穿过避空位304并与第一杆件1相配合。Referring to FIG. 7 , the adjustingmember 3 with a mirror-symmetric structure includes afirst guide piece 301 and asecond guide piece 302 arranged at intervals, and connecting arms are arranged at two intervals between thefirst guide piece 301 and thesecond guide piece 302 303 is connected, and the two connectingarms 303 are enclosed with thefirst guide piece 301 and thesecond guide piece 302 to form a space-avoidingposition 304. When the adjustingmember 3 is installed on thefirst rod member 1, thefirst guide piece 301 and thesecond guide piece 302 are respectively Located on both sides of thefirst rod 1 , thesecond rod 2 passes through theempty space 304 and is matched with thefirst rod 1 .

第一导片301和第二导片302中的至少一个设置第二导槽3b，与第一杆件1相连接的第二轴7与相应侧的第二导槽3b滑动配合，便能够实现第二轴7沿第二导槽3b滑动过程中靠近或远离第一轴6，满足对第一轴6和第二轴7的之间距离调整。At least one of thefirst guide piece 301 and thesecond guide piece 302 is provided with asecond guide groove 3b, and thesecond shaft 7 connected with thefirst rod 1 is slidably matched with thesecond guide groove 3b on the corresponding side, so as to realize Thesecond shaft 7 approaches or moves away from thefirst shaft 6 during sliding along thesecond guide groove 3b, so as to satisfy the adjustment of the distance between thefirst shaft 6 and thesecond shaft 7 .

可以理解的是，在调节件3包括第一导片301和第二导片302的实施例中，第一导片301和第二导片302均与第二杆件2转动连接，且转动轴线同轴，从而使得调节件3能够相对第二杆件2转动。第一导片301、第二导片302与第二杆件2之间的转动可以是采取同一个第一轴6，以增强调节件3对第一杆件1和第二杆件2之间位置调整稳定性。在其他实施例中，也可以采取不同的第一轴6，只要与第一导片301、第二导片302相连接的第一轴6同轴设置即可。相应地，调节件3开设轴孔3c的实施例中，轴孔3c可以是设置在第一导片301、第二导片302其中任何一个上，或者，第一导片301、第二导片302上均开设轴孔3c。It can be understood that, in the embodiment in which the adjustingmember 3 includes thefirst guide piece 301 and thesecond guide piece 302, thefirst guide piece 301 and thesecond guide piece 302 are both rotatably connected with thesecond rod member 2, and the axis of rotation is Coaxial, so that the adjustingmember 3 can rotate relative to thesecond rod member 2 . The rotation between thefirst guide piece 301 , thesecond guide piece 302 and thesecond rod member 2 may adopt the samefirst axis 6 to enhance theadjustment member 3 between thefirst rod member 1 and thesecond rod member 2 Position adjustment stability. In other embodiments, differentfirst shafts 6 may also be adopted, as long as thefirst shafts 6 connected to thefirst guide piece 301 and thesecond guide piece 302 are coaxially arranged. Correspondingly, in the embodiment in which the adjustingmember 3 has theshaft hole 3c, theshaft hole 3c may be provided on any one of thefirst guide piece 301 and thesecond guide piece 302, or thefirst guide piece 301 and thesecond guide piece 302. 302 are provided with shaft holes 3c.

该实施例中，调节件3的齿状边缘3a可以是位于第一导片301、第二导片302的其中一个上，或者，第一导片301、第二导片302上均设置有齿状边缘3a，只要止动件4上的锁止齿4a能够与相应地齿状边缘3a相啮合对调节件3起到锁止效果即可。例如，结合图7和图9所示，在第一导片301、第二导片302上均设置有齿状边缘3a时，止动件4上至少设有两个锁止齿4，该两个锁止齿4分别与第一导片301、第二导片302上的齿状边缘3a相对应，从而在止动件4对调节件3的位置进行锁定时，这种结构设置能够有效提高锁定稳定性。该实施例中，止动件4也可以只设置一个锁止齿4，只要该锁止齿4能够与第一导片301和第二导片302其中一个的齿状边缘3a相配合，实现对调节件3进行锁定即可。In this embodiment, thetoothed edge 3a of the adjustingmember 3 may be located on one of thefirst guide piece 301 and thesecond guide piece 302 , or both thefirst guide piece 301 and thesecond guide piece 302 are provided with teeth As long as the lockingteeth 4a on thestopper 4 can engage with the correspondingtoothed edges 3a, it is sufficient to lock the adjustingmember 3. For example, as shown in FIG. 7 and FIG. 9 , when both thefirst guide piece 301 and thesecond guide piece 302 are provided withtoothed edges 3 a , thestopper 4 is provided with at least two lockingteeth 4 . The lockingteeth 4 correspond to thetoothed edges 3a on thefirst guide piece 301 and thesecond guide piece 302 respectively, so that when thestopper 4 locks the position of theadjustment piece 3, this structure arrangement can effectively improve the Lock stability. In this embodiment, thestopper 4 can also be provided with only onelocking tooth 4, as long as the lockingtooth 4 can cooperate with thetoothed edge 3a of one of thefirst guide piece 301 and thesecond guide piece 302 to achieve the Theadjustment part 3 can be locked.

需要说明的是，止动件4的设置位置和结构形式还可以是其它情形。It should be noted that the arrangement position and structural form of thestopper 4 may also be other situations.
