此类感测电极可设置在包括刚性主干结构的导管远侧端部处，或者设置在刚性臂上。
Such sensing electrodes may be disposed at a catheter distal end comprising a rigid backbone structure, or over stiff arms.
刚性主干结构可由例如脊制成，所述脊在其两个端部处固定到轴，例如组装成篮形导管。
A rigid backbone structure may be made, for example, of spines that are secured at both their ends to a shaft, e.g., assembled into a basket catheter.
另选地，足够刚性的臂可仅保持在一个端部。
Alternatively, arms that are stiff enough can be held at one end only.
然而，在一些情况下，刚性远侧端部可能存在问题。
In some cases, however, a rigid distal end may be problematic.
例如，当标测心肌以获取电信号时，由刚性结构或刚性构件制成的诊断导管可通过与组织机械接触而触发异位心跳(即，由于过早心跳而导致的不规则心律)。
For example, while mapping the myocardium to acquire electrical signals, diagnostic catheters made of rigid structures or stiff members can trigger ectopic heartbeats (i.e., irregular heart rhythm due to a premature heartbeat) by mechanical contact with the tissue.
还存在心肌被例如刚性脊的边缘穿孔的风险。
There is also a risk of perforation of the myocardium by, for example, the edge of a stiff spine.
下文所述的本发明的实施方案提供了包括多个柔性脊的多臂导管，在下文中称为“柔性多臂导管”。
Embodiments of the present invention that are described hereinafter provide a multi-arm catheter comprising multiple flexible spines, referred to hereinafter as a ‘flexible multi-arm catheter.’
柔性脊包括高密度的直接地相对的感测电极对。
The flexible spines comprise a high density of diametrically opposing sensing electrode-pairs.
多个柔性脊从装配有软导管的轴的远侧端部的中心向外延伸，然后朝向轴向内弯曲，并且在轴的远侧端部上沿近侧方向向后弯曲。
The multiple flexible spines extend outward from a center of the distal end of the shaft that the soft catheter is fitted at and then curve inward towards the shaft and backwards in the proximal direction over the distal end of the shaft.
每个柔性脊弯曲而不被锚定在其另一个端部处，例如，通过将拉伸材料嵌入脊中。
Each flexible spine bends without being anchored at its other end, e.g., by embedding tensile material in the spine.
换句话讲，给定的柔性脊具有连接到轴的远侧端部的相应第一端部和自支撑且未锚定的相应第二端部，其中脊朝近侧弯曲，使得第二端部比第一端部更近侧。
In other words, a given flexible spine has a respective first end that is connected to the distal end of the shaft and a respective second end that is free-standing and unanchored, wherein the spine is bent proximally such that the second end is more proximal than the first end.
一些公开的实施方案利用柔性电路板来构造脊，该脊在顶侧和底侧上(即，在柔性电路板的直接地相对的表面上)均具有电极。
Some disclosed embodiments utilize a flexible circuit board to construct spines that have electrodes on both the top-side and under-side (i.e., over diametrically opposing surfaces of the flexible circuit board).
此类几何形状使得能够在每个电极对位置测量来自两个相反方向的信号。
Such a geometry enables measuring signals from two opposing directions per each electrode-pair location.
当柔性脊完全延伸时，面向轴的电极通常将不与组织接触。
When the flexible spines are fully extended, the electrodes that face the shaft will typically not be in contact with tissue.
当脊仍被部分地推出护套时，当这些“内部”电极仍在外侧上时，这些电极可能具有重要的临床意义，并且感测可在导管仍处于紧凑形式、部分地折叠在护套中时开始。
These electrodes may be clinically significant when the spines are still partially advanced out of the sheath, when these ‘interior’ electrodes are still on the exterior side, and sensing may commence while the catheter is still in a compact form, being partially folded in the sheath.
在一些实施方案中，电路板由柔性材料制成，该柔性材料允许电路板紧密折叠，以便在两个相对侧上形成电极。
In some embodiments, the circuit board is made of a flexible material that allows the circuit board to be tightly folded, in order to form the electrodes on two opposing sides.
可将具有高拉伸强度的薄材料诸如 或超高分子量聚乙烯(UHMWPE)夹置在折叠电路板的两个小面之间以迫使柔性电路板弯曲。
A thin material with high tensile strength, such as Vectran® or Ultra High Molecular Weight Polyethylene (UHMWPE), can be sandwiched between the two facets of the folded circuit board to force the flexible circuit board to bend.
所得的脊几何形状通过避免锋利边缘与心肌的接触来提供额外的结构和临床安全性。
The resulting spine geometry provides additional structural and clinical safety, by avoiding contact of sharp edges with the myocardium.
另选地或除此之外，柔性脊可包括一个或多个高拉伸强度纤维以控制其弯曲，诸如由液晶聚合物(LCP)、碳纤维、玻璃纤维和/或UHMWPE制成的纤维。
Alternatively, or additionally, the flexible spine may include one or more high-tensile-strength fibers to control its bending, such as ones made of Liquid Crystal Polymer (LCP), Carbon Fiber, Fiberglass, and/or UHMWPE.
在一些实施方案中，柔性电路具有以保持柔性脊的结构柔性的方式图案化为薄膜和/或嵌入纱线的电极导线。
In some embodiments, the flexible circuit has the electrodes conductive lines patterned as thin films and/or as an embedded yarn, in a way that maintains the structural flexibility of the flexible spine.
在一些实施方案中，用于迫使柔性电路板弯曲的材料的拉伸强度大于镍钛诺合金的拉伸强度。
In some embodiments, the tensile strength of the material used for forcing the flexible circuit board to bend is greater than that of Nitinol alloys.
即，对于相同的层或相同的纤维厚度，由使用上文列出的材料中的一种的层或纤维施加的张力高于如果由镍钛诺合金中的一种制成时的张力。
Namely, for a same layer or a same fiber-thickness, the tensile force exerted by the layer or a fiber using one of the above listed materials, is higher than if made of one of Nitinol alloys.
由镍钛诺合金制成的导管臂的示例为由Biosense Webster(Irvine，California)制造的 感测导管的臂。
An example of catheter arms that are made of a Nitinol alloy, are the arms of a Pentaray® sensing-catheter, made by Biosense Webster, Irvine, Calif.
本发明所公开的柔性多臂导管(其臂在从轴的远侧端部悬吊的同时朝近侧和向内自弯曲)可容纳具有高柔性和最小刚度的任何解剖结构。
The disclosed flexible multi-arm catheter, whose arms are self-bending proximally and inwardly while being suspended from the distal end of the shaft, can accommodate any anatomy with high flexibility and with minimum stiffness.
该设计允许医师安全地操纵心腔内的导管，并且以较小的异位搏动或穿孔风险从组织收集信号。
This design allows the physician to safely maneuver the catheter within a cardiac chamber and collect signals from tissue with less risk of ectopic beats or perforation.
因此，软多臂导管扩展了医师诊断某些心脏疾病的能力，尤其是在更易受心导管插入术的上述副作用影响的患者中。
The soft multi-arm catheter thus expands the capabilities of a physician to diagnose certain cardiac disorders, especially in patients who are more vulnerable to side-effects described above of cardiac catherization.
此外，柔性多臂设计可增加使用现有设计难以达到的解剖结构部分标测的可达性。
Moreover, the flexible multi-arm design can increase the accessibility to mapping of anatomy parts hard to access with existing designs.
图1为根据本发明的实施方案的基于导管的电解剖标测系统20的示意性图解。
FIG. 1 is a schematic, pictorial illustration of a catheter-based electro-anatomical mapping system 20, in accordance with an embodiment of the present invention.
系统20包括导管21，其中导管的轴22通过护套23插入患者28的心脏26中。
System 20 comprises a catheter 21, wherein a shaft 22 of the catheter is inserted into a heart 26 of a patient 28 through a sheath 23.
导管21的近侧端部连接到控制台31。
The proximal end of catheter 21 is connected to a control console 31.
在本文所述的实施方案中，导管21可用于任何合适的诊断目的，诸如心脏26中组织的电生理标测和/或电解剖标测。
In the embodiment described herein, catheter 21 may be used for any suitable diagnostic purposes, such as electrophysiological mapping and/or electro-anatomical mapping of tissue in heart 26.
控制台31包括具有合适前端的处理器38，通常为通用计算机。
Console 31 comprises a processor 38, typically a general-purpose computer, with suitable front end.
控制台31还包括接口电路41，该接口电路用于从导管21接收信号，以及用于连接到处理器38控制的系统20的其他部件。
Console 31 comprises also an interface circuitry 41 for receiving signals from catheter 21, as well as for connecting to other components of system 20 that processor 38 controls.
医生30将轴22插入穿过躺在桌子29上的患者28的血管系统。
A physician 30 inserts shaft 22 through the vascular system of patient 28 lying on a table 29.
如在插图25中所见，导管21包括装配在轴22的远侧端部处的软多臂感测导管40(在被推出护套23之后)。
As seen in an inset 25, catheter 21 comprises a soft multi-arm sensing catheter 40 fitted at the distal end of shaft 22 (after being advanced outside sheath 23).
在轴22的插入期间，软多臂导管40由护套23保持在塌缩构型中。
During the insertion of shaft 22, soft multi-arm catheter 40 is maintained in a collapsed configuration by sheath 23.
通过将导管40包含在塌缩构型中，护套23还用于使目标位置沿途的血管创伤最小化。
By containing catheter 40 in a collapsed configuration, sheath 23 also serves to minimize vascular trauma along the way to target location.
医师30通过使用导管的近侧端部附近的操纵器32和/或来自护套23的偏转操纵轴22，来将软多臂导管40导航到心脏26中的目标位置。
Physician 30 navigates soft multi-arm catheter 40 to a target location in heart 26 by manipulating shaft 22 using a manipulator 32 near the proximal end of the catheter and/or deflection from the sheath 23.
一旦轴22的远侧端部到达目标位置，医师30回缩护套23，或推进轴22，从而使软多臂感测导管40伸展。
Once the distal end of shaft 22 has reached the target location, physician 30 retracts sheath 23, or advances shaft 22, letting soft multi-arm sensing catheter 40 expand.
然后，医师操作控制台31，以便使用电极24(见图2)感测来自目标位置处的组织的信号。
The physician then operates console 31 so as sense signals using electrodes 24 (seen in FIG. 2 ) from tissue at the target location.
尽管图示的实施方案具体地涉及软多臂感测导管40用于心脏组织的电生理感测的用途，但系统20的元件和本文所述的方法可另外地应用于控制多电极消融装置，诸如圆形消融导管、球囊消融导管和多臂消融装置。
Although the pictured embodiment relates specifically to the use of a soft multi-arm sensing catheter 40 for electrophysiological sensing of heart tissue, the elements of system 20 and the methods described herein may additionally be applied in controlling multi-electrode ablation devices, such as circular ablation catheters, balloon ablation catheters, and multi-arm ablation devices.
图2是根据本发明的实施方案的软多臂感测导管40的示意性图解。
FIG. 2 is a schematic, pictorial view of soft multi-arm sensing catheter 40, in accordance with an embodiment of the present invention.
如图所示，软多臂导管40装配在轴22的远侧端部上。
As seen, soft multi-arm catheter 40 is fitted on a distal end of shaft 22.
导管40由多个柔性脊制成，所述多个柔性脊从轴22的远侧端部的中心沿对角线向外延伸。
Catheter 40 is made of multiple flexible spines that extend diagonally outward from a center of the distal end of shaft 22.
脊随后在轴22的远侧端部上沿近侧方向向内弯曲，其中脊的另一个端部为自支撑且未锚定的。
The spines then bend inwardly, in the proximal direction, over the distal end of shaft 22, with their other end free-standing and unanchored.
矩形感测电极24形式的多个金属元件在柔性脊27的两个小面上图案化，从而允许检测来自相反方向的信号。
A multiplicity of metallic elements in the form of rectangular sensing electrodes 24 are patterned over the two facets of flexible spines 27 so as to allow detection of signals from opposing directions.
在脊27被完全推出护套之前，在脊完全伸展之后面向轴的电极24可能仍然具有重要的临床意义。
Electrodes 24 that are facing the shaft after the spines fully expand may still be clinically significant prior to spines 27 being fully advanced out of the sheath.
当脊27被部分地推出时，此类内部电极在外侧上，并且感测可在导管仍处于紧凑形式、部分地折叠在护套中时开始。
When spines 27 are partially advanced out, such interior electrodes are on the exterior side, and sensing may commence while the catheter is still in a compact form, being partially folded in the sheath.
柔性脊27实际上是半浮动的，以便轻轻地适应脊可能接触的解剖结构。
Flexible spines 27 are practically semi-floating so as to gently accommodate an anatomy that the spines may come in contact with.
脊27的边缘指向轴22，以便避免脊的边缘与组织的尖锐接触。
The edges of spines 27 are pointing toward shaft 22 so as to avoid sharp contact of an edge of a spine with tissue.
脊27被设计成当向内按压时，例如当压靠在组织的表面上时，施加弹性反向力。
Spines 27 are designed to apply elastic opposing force when pressed inward, for example when pressed against a surface of tissue.
本发明涉及一种靴式辊(shoe roll，靴辊)端部模块，尤其涉及一种具有便于调整辊头(roll head)的位置的分度装置(indexing means)的靴式辊端部模块。
The invention pertains to a shoe roll end module and in particular, to a shoe roll end module having indexing means to facilitate adjustment of a roll head's position.
在现有技术的偏心靴式压榨辊中，带的旋转中心与辊的轴的中心之间存在偏心。
In prior art eccentric shoe press rolls, there is an eccentricity between the belt's rotating center and the center of the roll's axle.
偏心越大，辊的直径越大。
The eccentricity becomes the larger, the larger the diameter of the roll becomes.
与具有同心辊/带结构的几何形状相比，这种偏心使得脱水时间更长(当在机器运行方向上的靴长度比同心辊/带的长度长时)。
This eccentricity enables a longer water removal time than a geometry having concentric roll/belt structure (when the shoe length in machine running direction is longer than with concentric roll/belt).
如今，偏心和在保持所需的带张力的同时旋转辊头以调节带伸长或带缩短的需要导致辊端部零件相当复杂且制造昂贵。
Nowadays, the eccentricity and the need for rotating the roll head to adjust belt elongation or belt reduction while keeping the belt tension as required causes roll end pieces that are rather complex and expensive to manufacture.
此外，这种辊头结构的组装很慢并且需要大量的装配(fitting)工作，特别是在整个辊端部组件中。
Moreover, the assembly of such a roll head structure is slow and requires lot of fitting work especially in the whole roll end assembly.
这种单独的辊头和底座(pedestal，基座)结构可以例如在专利文件US 5733415A和专利文件EP 01619299B1中找到。
Examples of such separate roll head and pedestal structures can be found e.g. in document US 5 733 415 A and in document EP 01 619 299 B1.
因此，需要改进悬置结构(pending structure)，并提供靴式辊端部模块，该靴式辊端部模块具有能够改进靴式压榨中带的张力调节的辊头。
Thus, there is a need to improve the pending structures and to provide a shoe roll end module with a roll head capable of improving adjustment of a belt's tension in a shoe press.
根据本发明，一种靴式辊端部模块包括底座和辊头，该底座具有轴孔，该轴孔被构造为容纳靴式辊的轴，该辊头被构造为保持带。
According to the invention, a shoe roll end module comprises a pedestal, having an axle hole configured to accommodate an axle of a shoe roll and a roll head configured to hold a belt.
套圈(ferrule，套管)支撑在底座上并指向底座的内侧(朝向包括靴式辊的造纸机或纸板机的中心)。
A ferrule is supported on the pedestal and directed to an inner side of the pedestal (towards the center of a paper or board machine comprising the shoe roll).
辊头以可轴向移动的方式支撑在套圈上。
The roll head is supported on the ferrule in an axially movable manner.
优选地，套圈的内径可以被构造成超过轴的轴径，使得整个端部模块仅通过一次吊装(lift，提升)就可以装配到轴上。
Preferably, an inner diameter of the ferrule can be configured to exceed an axle diameter of the axle so that the whole end module can be fitted to the axle by only one lifting.
此外，至少两个杆状分度装置被引导穿过底座中的各个孔，并以等角度距离围绕轴孔以预定距离布置，并且被构造成控制辊头相对于所述端部模块中的底座的移动。
Moreover, at least two rod like indexing means are guided through respective bores in the pedestal and arranged with a predetermined distance around the axle hole in an equal angular distance, and being configured to control the movement of the roll head in relation to the pedestal in the said end module.
优选地，分度装置可以布置在套圈的径向外部。
Preferably, the indexing means can be arranged radially outside of the ferrule.
在需要调整带的张力或改变带的位置以减少带的磨损的情况下，以上述方式设置的杆状分度装置使得能够平滑和精确地控制辊头朝向底座的移动。
Provision of the rod like indexing means in the above-described manner enables a smooth and accurate control of the movement of the roll head towards the pedestal in a case where an adjustment of the belt's tension or a position change of the belt in order to reduce wear of the belt is required.
此外，由于提供了至少两个分度装置，因此可以避免由于分度装置卡住而发生的问题。
Moreover, problems occurring due to jamming of the indexing means can be avoided, since there are at least two indexing means provided.
在某些情况下，当重的外分度杆靠近套圈的外表面放置时，重的外分度杆可以控制头的移动。
In some cases a heavy outer indexing rod can control the movement of the head when placed close to ferrule's outer surface.
-移动装置包括缸(cylinder，汽缸)装置和弹簧装置(但也可包括螺杆装置或可替代地是螺杆装置)；
In particular, the indexing means can comprise control means and movement means; the control means can comprise rod-, nut-, head-, and scale-means; the movement means comprise cylinder means and spring means (but also or alternatively screw means); an annular cylinder can initiate every movement by relieving the indexing nuts so that those are easy to be turned to a selected position (This advantage is also explained in the description of Fig. 1 ).
有利地，每个分度装置可以形成为单作用环形缸，该单作用环形缸被构造成将辊头朝向底座推动。
Advantageously, each of the indexing means can be formed as a single action annular cylinder configured to urge the roll head towards the pedestal.
可选地，每个分度装置可以形成为螺杆，该螺杆与设置在连接到底座的分度螺母中的螺纹孔螺纹接合，并且该螺杆具有与底座的外侧接合的分度头。
Alternatively, each of the indexing means can be formed as a screw, the screw being in thread engagement with a thread bore provided in an indexing nut in connection to the pedestal and having an indexing head being in engagement with an outer side of the pedestal.
有利地，穿过底座的孔可以在其指向辊头的一侧具有容纳槽(accommodationpocket)，并且至少一个压缩弹簧被容纳在每个容纳槽中，用于分度返回移动装置。
Advantageously, the bores through the pedestal can have an accommodation pocket on their side directed to the roll head, and at least one compression spring is accommodated in each accommodation pocket for indexing return movement means.
此外，可以设置具有不同弹簧刚度(spring rate，弹簧劲度系数)的多个同轴布置的弹簧。
Moreover, a plurality of coaxially arranged springs having a different spring rate can be provided.
从而，可以确定偏置弹簧(biasing spring)的弹簧常数，使得即使螺杆与辊头中的螺纹孔螺纹接合，分度头的相对位置也保持不变。
Thereby, a spring constant of the biasing spring can be determined such, that, despite thread engagement of the screws with the thread bore in the roll head, relative positions of the indexing heads are maintained.
在转动分度螺母以及环形缸减压时，偏置弹簧进行返回移动(这是每次移动的结束状态，从而消除了液压油泄漏)。
Biasing springs make the return movement when the indexing nuts are turned and the annular cylinder is depressurized (which is the end status of every movement so that hydraulic oil leakage is eliminated).
不需要恒定的压力，分度螺母和弹簧使辊头保持在其分度位置。
No constant pressure is needed and indexing nuts and springs keep the roll head on its indexed position.
有利地，每个分度装置可以形成为工作缸，其一端附接到辊头，其另一端附接在底座处。
Advantageously, each of the indexing means can be formed a as a working cylinder, having one of its ends attached with the roll head and having the other of its ends attached at the pedestal.
有利地，每个分度装置可以形成为杆，其一端附接到辊头，另一端被容纳在中空的分度螺母中，该分度螺母与杆螺纹接合。
Advantageously, each of the indexing means can be formed as a rod having one end attached to the roll head, and the other end accommodated in a hollow indexing nut, the indexing nut being in thread engagement with the rod.
优选地，杆可以被引导通过布置在底座的外侧或内侧处的滑动轴承衬套，并且螺杆与布置在底座外部的分度螺母螺纹接合。
Preferably, the rod can be guided through a slide bearing bush arranged at the outer side or inner side of the pedestal, and the screw is in thread engagement with an indexing nut being arranged outside of the pedestal.
此外，有利地，可以在底座的内侧处设置工作缸，该工作缸被构造为改变辊头位置。
Moreover, advantageously, a working cylinder can be provided at the inner side of the pedestal, the working cylinder being configured to change the roll head position.
靴式辊头可以包括控制器，该控制器被构造为同时接合(多个)分度装置。
The shoe roll head can comprise a controller configured to engage the indexing means simultaneously.
应当注意，分度装置的同时操作可以手动完成也可以自动完成。
It is to be noted, that simultaneous operation of the indexing means can be done manually as well as automatically.
在靴式辊头中，有利地，轴孔可以具有多边形截面，并且轴孔的一个或两个表面用作扭矩表面。
In the shoe roll head, advantageously, the axle hole can have a polygonal section and one or two surfaces of the axle hole serve as a torque surface.
这里，扭矩表面被定义为轴孔的表面，其被构造为吸收在靴式辊操作期间发生的轴的扭矩。
Here, a torque surface is defined as a surface of the axle hole, which is configured to absorb a torque of the axle occurring during operation of the shoe roll.
此外，具有来自底座的支撑的靴式辊端部模块使辊头的支撑进一步远离轴的受力部分，在该受力部分处，该轴的轮廓从轴颈(axle stub，轴短柱)变为压榨靴的支撑梁。
Moreover, the shoe roll end module with support from the pedestal moves the support of the roll head further away from the stressed part of the axle where its profile changes from an axle stub to a support beam for a press shoe.

In addition, the terms implant and prosthesis, and variations thereof, can be used interchangeably.
本公开涉及髓内植入物和压紧(压缩、压迫)仪器，所述压紧仪器在内部通过所述髓内植入物提供毗邻关节的多个骨骼部分或多个骨骼的压紧。
The present disclosure is directed to intramedullary implants and compression instruments that provide for compression of bone parts or bones adjoining a joint internally through the intramedullary implant.
以这种方式，可以实现更简单和更有效的压紧技术，这消除了与其他压紧技术或方法相关联的缺陷。
In this way, a simpler and more-effective compression technique can be carried out, which removes deficiencies associated with other compression techniques or methods.
参考图1，髓内植入物10以髓内钉(例如，IM踝钉)的形式示出。
Referring to FIG. 1, an intramedullary implant 10 is shown in the form of an intramedullary nail (e.g., an IM ankle nail).

FIG. 1 also illustrates a jig nose 60 and a compression instrument 90 attachable to jig nose 60 for applying compression across bone parts or bones adjoining a joint internally through implant 10.
为方便起见，本公开的其余部分应涉及使用植入物10、夹具凸头60和压紧仪器90来将毗邻关节的骨骼压紧在一起，但是同样可以预期这种植入物和仪器可以替代地用于将骨骼碎片或骨骼部分压紧在一起(例如，在修复骨折的情况下)。
For the sake of convenience, the remainder of the disclosure shall refer to use of implant 10, jig nose 60, and compression instrument 90 to compress bones adjoining a joint together, although it is equally contemplated that such implants and instruments can instead be used to compress bone fragments or parts together (e.g., in the case of repairing a fracture).
图10A-D示出了植入物10。
FIGS. 10A-D illustrate implant 10.
植入物10可以具有轴部12，所述轴部12在轴部12的近侧部分和轴部12的远侧部分之间具有弯曲部11。
Implant 10 can have a shaft 12 with a bend 11 between a proximal section of shaft 12 and a distal section of shaft 12.
弯曲部11可以在约两度至约十五度(2-15°)之间的任何地方，在另一个示例中，在约五度至约十度(5-10°)之间的任何地方，或者在又一个示例中，为约五度(5°)。
Bend 11 can be anywhere between about two degrees to about fifteen degrees (2-15°), in another example anywhere between about five degrees to about ten degrees (5-10°), or in yet another example about five degrees (5°).
因此，轴部12的近侧部分可以限定轴线21，并且轴部12的远侧部分可以限定轴线23，并且轴线21、23可以相交以形成任何上述角度。
Thus, the proximal section of shaft 12 can define an axis 21 and the distal section of shaft 12 can define an axis 23, and the axes 21, 23 can intersect to form any of the aforementioned angles.
植入物10还可包括一组远侧开口14、16、18、20，所述一组远侧开口14、16、18、20用于接收骨螺钉52，如图9A-C所示。
Implant 10 can also include a set of distal openings 14, 16, 18, 20 for receiving bone screws 52, as shown in FIGS. 9A-C.
任何开口14、16、18、20可以以任何组合的形式带螺纹或不带螺纹。
Any of openings 14, 16, 18, 20 can be threaded or unthreaded, in any combination.
在一个示例中，开口14、16、18、20还可以基本垂直于轴线23布置，或者开口14、16、18、20中的任一个可以是类似于下面描述的第一狭槽(凹槽)24的狭槽。
Openings 14, 16, 18, 20 can also be arranged substantially perpendicular to axis 23, in an example, or any of openings 14, 16, 18, 20 can be a slot similar to first slot 24 described below.
植入物10还可以包括在轴部12的近侧部分处穿过轴部12的第一成角度开口22。
Implant 10 can further include a first angled opening 22 through shaft 12 at the proximal section of shaft 12.
在一个示例中，开口22可以向近侧以约三十五度至约五十度(35-50°)之间的角度穿过轴部12成角度，或者备选地向近侧相对于轴线21以约四十五度(45°)的角度成角度。
In an example, opening 22 can be angled through shaft 12 proximally by between about thirty five degrees to about fifty degrees (35-50°), or alternatively about forty five degrees (45°) proximally relative to axis 21.
开口22还可以向内侧(向中间)相对于延伸穿过患者脚踝的矢状平面41(如图9C所示)以大致在约二十度至约三十度(20-30°)之间的任何地方的角度成角度，在一示例中以约二十八度(28°)的角度成角度。
Opening 22 can also be angled approximately anywhere between about twenty degrees to about thirty degrees (20-30°), in an example about twenty eight degrees (28°), medially relative to a sagittal plane 41 extending through the patient's ankle, as illustrated in FIG. 9C.
如图9A-C所示，这可以产生如下情况，其中骨螺钉53可以向下穿过开口22插入患者的胫骨40和距骨44中。
As shown in FIGS. 9A-C, this can create a situation in which a bone screw 53 can be inserted downwardly through opening 22 and into a patient's tibia 40 and talus 44.
在一个示例中，螺钉53大约是六十二点五毫米(62.5mm)长并且当穿过开口22插入时可以延伸至胫骨40和距骨44中。
In an example, screw 53 is approximately sixty two and a half millimeters (62.5 mm) in length and can extend into tibia 40 and talus 44 when inserted through opening 22.
