Description
本發明係一骨固定器，尤其指同時具有高安全性及高舒適性之互鎖式骨固定器。
The invention is a bone anchor, especially an interlocking bone anchor which has high safety and high comfort at the same time.
按，人體各部位之骨骼形狀各不相同且構造複雜，一旦發生骨折等傷害，而在醫學上提供治療與復健的方式通常需依據患部的骨骼結構而提供適當的治療。若遇車禍、跌倒等意外造成骨折之情形(例如：一般骨折或粉碎性骨折)、病患本身的骨質疏鬆或是骨折部位靠近關節甚至延伸至關節處，無法以石膏固定或其他治療方式時，骨板與骨釘是最常用於治療骨折的固定物。
由於科技的進步，新一代的骨釘骨板在近幾年陸續研發出來，以互鎖式骨板及骨釘為例，螺絲頭及骨板上之固定孔上都有螺紋，可以將螺絲直接鎖定在骨板上，使骨折的固定更堅固，不像傳統的設計，螺絲容易鬆脫，如此針對粉碎性骨折或骨質疏鬆患者，可以得到較好的固定。當骨關節面與肌肉組織接觸之區域發生骨折創傷時，由於骨板會覆蓋於關節面上方，因此骨板在植入病患體內肌肉組織較薄處時（如鎖骨、橈骨），會因骨板本身之厚度使病患在該處感到不適，甚至影響患者骨折部位的活動性，進而可能限制到復原後關節可活動之範圍，故，如何把骨板厚度降低，又要具有一定之固定力，實為現今所面臨之重要難題。
請一併參照第一A圖與第一B圖，如圖所示，其係為一般互鎖式骨板，當一螺絲1’由垂直方向鎖入一骨板2’時，藉由該螺絲1’之一螺絲頭10’外表面之一外螺牙102’與該骨板2’之一固定孔20’之一內螺牙202’相互鎖固，故除了該螺絲1’之該螺絲柱12’鎖於下方之骨頭(未圖示)外，具有更高之固定力。又如第二A圖與第二B圖，一般而言，無論是一般骨折或粉碎性骨折，為了增加固定力或拉緊該些骨塊而使之復原，該螺絲1’需傾斜而固定於骨頭上，尤其是需使用較薄之該骨板2’之部位（如鎖骨、手部），在薄化增加舒適度之同時，該螺絲頭10’外表面之該外螺牙102’大約會有一半的螺牙露出，其無法有效的與該骨板2’互鎖，當病患患處受到外力或有較大之動作時可能導致該螺絲1’與該骨板2’鬆脫而產生危險。再者，如第三圖所示，若為了增加固定力而增加該骨板2’之厚度T2（相較於第二A圖該骨板厚度T1），該骨板2’將使病患在該處感到不適，甚至影響患者骨折部位的活動性。
現今傳統之骨固定器尚有上述之該些缺失故研發新一代的骨固定器有其必要性。因此，如何突破、解決習知技術此類缺失問題，進而提升骨板之安全性、舒適性與其經濟效益，誠為業界或有智之士目前應努力解決、克服之重點項目。
緣此，本發明人有鑑於骨固定器之問題缺失及其結構設計上未臻理想之事實，本案發明人即著手研發其解決之方案，希望能開發出一種更具安全性、舒適性與經濟效益之互鎖式骨固定器，以服務社會大眾及促進此業之發展，遂經多時之構思而有本發明之產生。
According to the various parts of the human body, the bone shape is different and the structure is complex. Once a fracture or the like occurs, the medical treatment and rehabilitation methods usually provide appropriate treatment according to the bone structure of the affected part. In the event of a car accident, a fall, etc., such as a fracture (such as a general or comminuted fracture), osteoporosis of the patient itself, or a fracture site close to the joint or even to the joint, which cannot be fixed by plaster or other treatment. Bone plates and bone nails are the most commonly used fixes for the treatment of fractures.
Due to the advancement of technology, a new generation of bone nail plate has been developed in recent years. Taking interlocking bone plates and bone nails as an example, the screw holes and the fixing holes on the bone plate are threaded, and the screws can be directly Locked on the bone plate, the fixation of the fracture is stronger, unlike the traditional design, the screw is easy to loose, so that for patients with comminuted fracture or osteoporosis, better fixation can be obtained. When a fracture occurs in the area where the joint surface of the bone and the muscle is in contact with the muscle tissue, since the bone plate covers the joint surface, the bone plate is implanted in the thinner part of the muscle tissue (such as the clavicle and the tibia). The thickness of the plate itself makes the patient feel uncomfortable there, and even affects the mobility of the fracture site of the patient, which may limit the range of motion of the joint after recovery. Therefore, how to reduce the thickness of the bone plate and have a certain fixing force It is an important problem facing today.
Please refer to the first A picture and the first B picture together, as shown in the figure, which is a general interlocking bone plate, when a screw 1' is locked into a bone plate 2' by a vertical direction, by the screw 1' one of the outer surface of one of the screw heads 10' and the external thread 102' of one of the fixing holes 20' of the bone plate 2' are interlocked with each other, so the screw column except the screw 1' The 12' locks to the underlying bone (not shown) and has a higher fixation force. Another example is the second A picture and the second B picture. Generally speaking, whether it is a general fracture or a comminuted fracture, in order to increase the fixing force or tighten the bone pieces to restore it, the screw 1' needs to be inclined and fixed. On the bone, especially in the thinner part of the bone plate 2' (such as the clavicle, hand), while the thinning increases the comfort, the outer thread 102' of the outer surface of the screw head 10' is about Half of the thread is exposed, and it cannot effectively interlock with the bone plate 2'. When the patient suffers from external force or has a large movement, the screw 1' and the bone plate 2' may be loosened and dangerous. . Furthermore, as shown in the third figure, if the thickness T2 of the bone plate 2' is increased in order to increase the fixing force (the thickness T1 of the bone plate compared to the second A figure), the bone plate 2' will cause the patient to It feels uncomfortable and even affects the mobility of the patient's fracture site.
Nowadays, the traditional bone fixers still have the above-mentioned defects, so it is necessary to develop a new generation of bone fixers. Therefore, how to break through and solve the problem of the lack of conventional technology, and thus improve the safety, comfort and economic benefits of the bone plate, is the key project that the industry or intelligent people should try to solve and overcome.
Therefore, the inventors of the present invention have developed a solution to the problem that the problem of the bone anchor is missing and the structural design is not ideal, and it is hoped that a more secure, comfortable and economical development can be developed. The benefit of the interlocking bone anchors is to serve the public and promote the development of this industry.

為使 貴審查委員對本發明之結構特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：
於先前技術之該些互鎖式骨固定器，大多數厚度較大之骨板具有較佳之固定力，但骨板之厚度較厚而導致病患之不適，故無法應用於需使用較薄骨板之患部(如鎖骨、手部)，而為了該些患處而設計之較薄之骨板，該螺絲需傾斜而固定於骨板上時，均有螺絲之螺牙露出而導致鎖固力不佳之情形，且該螺絲之凸出尖點易造成患處之皮膚凸出而感到不適，亦會影響皮膚外觀（肌肉較薄處），故設計此互鎖式骨固定器以達成高安全性與高舒適性之目標。
請參考第四圖，其係本發明互鎖式骨固定器之一較佳實施例之骨板區域剖視示意圖，如圖所示，本發明之一互鎖式骨固定器1係包含一骨板本體10，該骨板本體10上具有至少一固定孔102，為方便說明其技術內容，本實施例係將一連續內螺牙(圖中所標示之1042、1062、1082)分別以一第一內螺牙1042、一第二內螺牙1062及一第三內螺牙1082稱之，該固定孔102之內側具有一第一內側壁104及一第二內側壁106，該第一內側壁104之表面具有該第一內螺牙1042，該第二內側壁106之表面具有該第二內螺牙1062，該第一內螺牙1042之數量少於該第二內螺牙1062，其中該第一內側壁104進一步向上沿伸設有一側壁108，該側壁108之內側設有該第三內螺牙1082。
上述之該固定孔102可垂直設置於該骨板本體10，該固定孔102亦可傾斜設置於該骨板本體10，本實施例以該固定孔102為傾斜狀作一說明。再者，該第一內側壁104、該第二內側壁106及第三內側壁108之內側可形成倒錐狀、圓柱狀或其他形狀，本實施例之該固定孔102以倒錐狀作一說明，故該第一內側壁104、該第二內側壁106及第三內側壁108之內側由上至下呈內縮狀，該第一內側壁104及該第二內側壁106頂端之開口直徑D1大於該第一內側壁104及該第二內側壁106底端之開口直徑D2。該固定孔102除該第一內螺牙1042與該第二內螺牙1062能與一螺絲之螺絲頭(此未圖示)相互固鎖固外，更包含該第三內螺牙1082能與裸露出的螺絲頭(可相較於第二B圖)相互鎖固，故提升該互鎖式骨固定器1之鎖固力，如此使螺絲不輕易與該骨板本體10鬆脫分離，進而具有高安全性。此外，因具有該第三內螺牙1082之結構能增加鎖固力，故該固定孔102之結構應用於較薄厚度之骨板(如鎖骨、手部之骨板)，讓使病患之肌肉與皮膚不會感到不適，且傾斜之螺絲凸出尖點因該第三內側壁108而變得較滑順，降低患處之皮膚因凸出而感到不適，亦降低皮膚之外觀影響(較平滑)，進而具有高舒適性。
然，習知技術之骨固定器未包含該側壁108，故其鎖固力不佳，易因外力或病患之活動使螺絲與該骨板本體10分離，進而造成病患安全上之疑慮，本實發明解決上述之問題，透過該第三內螺牙1082以加強該骨板本體10之鎖固力，尤其較薄之骨板具有更佳之固定功效，再者，該第三內側壁108能增加該骨板本體10與螺絲之平滑性以降低患處之皮膚因凸出而感到不適，故能同時具有高安全性與高舒適性。
再者，請一併參閱第五圖，其係本發明互鎖式骨固定器之上述實施例之骨板區域剖視實施示意圖，如圖所示，其係以上述實施例為基礎，再進一步說明該互鎖式骨固定器1之使用狀態。其中，該第一內螺牙1042、該第二內螺牙1062及該第三內螺牙1082之螺距、導程、外徑、內徑及螺紋角可相同，再者，該第一內側壁104及該第二內側壁106之底端延伸環設有一第四內側壁109。此外，該互鎖式骨固定器1更包含至少一螺絲12，其係具有一螺絲頭122與一螺絲柱124，該螺絲頭122連接於該螺絲柱124之上，該螺絲頭122之直徑對應於該第一內側壁104、該第二內側壁106及該第三內側壁108之開口直徑，亦即該螺絲頭122由上至下呈內縮狀(倒錐狀)，其中該螺絲頭122之外側環設有第一螺牙部1222，該螺絲柱124之外側環設有第二螺牙部1242。
在使用時，由於該第一內螺牙1042、該第二內螺牙1062及該第三內螺牙1082之螺距、導程、外徑、內徑及螺紋角相同，該第一螺牙部1222可直接螺設於該第一內螺牙1042、該第二內螺牙1062及該第三內螺牙1082，該螺絲柱124穿設於該第四內側壁109之內側。透過上述各部會之螺固，可使該螺絲12與該骨板本體10相互鎖固，並進一步使部分之該螺絲柱124鎖固於一骨頭(未圖示)上，而該第三內螺牙1082可增加該螺絲頭122靠近該第一內螺牙1042之一側之鎖固的螺牙牙數，故能提升鎖固力。請進一步參閱第六圖，除上述情形外，若該固定孔102設置於該骨板本體10較薄之一邊緣100時，若不將該第一螺牙部1222之大部分外露而降低鎖固力，亦需透過該側壁108內側之該第三內螺牙1082以使該第一螺牙部1222與該固定孔102之互鎖固定力增加。
此外，再一併參閱第七圖與第八圖，其係上述實施例之骨板立體示意圖與骨板立體分解示意圖。於此可更清楚該骨板本體10之該固定孔102之整體立體結構，如圖所示，該骨板本體10具有複數該固定孔102及複數個該螺絲12，當該些固定孔102之該第一內螺牙1042之數量少於於該第二內螺牙1062（參第四圖），透過增設該側壁108內側以使該第一螺牙部1222與該固定孔102之互鎖固定力增加，其中，該側壁108與該骨板本體10最佳為一體成形，亦可使該側壁108額外設之於該第一內側壁104之延伸處（參第四圖），其均可達到增加鎖固力以達高安全性之目的，此外，該側壁108可呈玄月狀以包覆該螺絲12，更能使傾斜之螺絲凸出尖點因該第三內側壁108而變得較滑順，更提升患處之皮膚因該骨板本體10較平滑而感到之舒適性。
本發明之該互鎖式骨固定器藉1由前述構成，在保有較薄之該骨板本體10時，透過該側壁108以加強鎖固力，故能防止該骨板本體10與該螺絲12鬆脫而具有高安全，且較薄與較平滑之該骨板本體10能讓使病患之肌肉與皮膚不會感到不適，進而具有高活動性及高舒適性。
惟以上所述者，僅為本發明之較佳實施例而已，並非用來限定本發明實施之範圍，舉凡依本發明申請專利範圍所述之形狀、構造、特徵及精神所為之均等變化與修飾，均應包括於本發明之申請專利範圍內。

For a better understanding and understanding of the structural features and the achievable effects of the present invention, the preferred embodiments and detailed descriptions are provided as follows:
In the interlocking bone anchors of the prior art, most of the thicker bone plates have a better fixing force, but the thickness of the bone plate is thicker and causes discomfort to the patient, so it cannot be applied to the use of thinner bone. The affected part of the board (such as the clavicle, the hand), and the thin bone plate designed for the affected part, the screw needs to be tilted and fixed on the bone plate, the screw thread is exposed, and the locking force is not In the best case, and the protruding point of the screw is easy to cause the skin of the affected area to bulge and feel uncomfortable, and also affect the appearance of the skin (thin muscles), so the interlocking bone anchor is designed to achieve high safety and high. The goal of comfort.
Please refer to the fourth figure, which is a cross-sectional view of a bone plate in a preferred embodiment of the interlocking bone anchor of the present invention. As shown in the figure, the interlocking bone anchor 1 of the present invention comprises a bone. The plate body 10 has at least one fixing hole 102 on the bone plate body 10. For convenience of description, the present embodiment uses a continuous internal thread (1042, 1062, 1082 indicated in the figure) as a first An inner thread 1042, a second inner thread 1062 and a third inner thread 1082 are said. The inner side of the fixing hole 102 has a first inner side wall 104 and a second inner side wall 106. The first inner side wall The surface of the first internal thread 104 has a second internal thread 1062, and the first internal thread 1042 is smaller than the second internal thread 1062. The first inner side wall 104 further defines a side wall 108 extending upwardly, and the third inner thread 1082 is disposed on the inner side of the side wall 108.
The fixing hole 102 can be vertically disposed on the bone plate body 10, and the fixing hole 102 can also be disposed obliquely on the bone plate body 10. In this embodiment, the fixing hole 102 is inclined. Furthermore, the inner side of the first inner side wall 104, the second inner side wall 106 and the third inner side wall 108 may be formed into an inverted cone shape, a column shape or other shapes. In the embodiment, the fixing hole 102 is formed in an inverted cone shape. The inner side of the first inner side wall 104, the second inner side wall 106, and the third inner side wall 108 are retracted from top to bottom, and the opening diameters of the first inner side wall 104 and the second inner side wall 106 are open. D1 is larger than the opening diameter D2 of the first inner side wall 104 and the bottom end of the second inner side wall 106. The fixing hole 102 further includes the first internal thread 1042 and the second internal thread 1062 being locked to a screw head (not shown), and further comprising the third internal thread 1082. The exposed screw heads (which can be locked compared to the second B) are mutually locked, so that the locking force of the interlocking bone anchor 1 is increased, so that the screws are not easily separated from the bone plate body 10, and thus High security. In addition, since the structure of the third internal thread 1082 can increase the locking force, the structure of the fixing hole 102 is applied to a thin-thickness bone plate (such as a bone plate of a clavicle or a hand), so that the patient is Muscle and skin do not feel uncomfortable, and the protruding point of the inclined screw becomes smoother due to the third inner side wall 108, which reduces the discomfort of the skin of the affected part due to the protrusion, and also reduces the appearance of the skin (smooth ), which in turn has high comfort.
However, the bone holder of the prior art does not include the side wall 108, so the locking force is not good, and the screw is easily separated from the bone body 10 due to the external force or the activity of the patient, thereby causing the patient's safety concerns. The present invention solves the above problems, and the third internal thread 1082 is used to strengthen the locking force of the bone plate body 10, and the thinner bone plate has better fixing effect. Moreover, the third inner side wall 108 can The smoothness of the bone plate body 10 and the screw is increased to reduce the discomfort of the skin of the affected part due to the protrusion, so that high safety and high comfort can be simultaneously achieved.
In addition, please refer to FIG. 5, which is a schematic cross-sectional view of the bone plate region of the above embodiment of the interlocking bone anchor of the present invention, as shown in the figure, which is further based on the above embodiment. The state of use of the interlocking bone anchor 1 will be described. The pitch, lead, outer diameter, inner diameter, and thread angle of the first inner thread 1042, the second inner thread 1062, and the third inner thread 1082 may be the same. Further, the first inner side wall A fourth inner side wall 109 is defined in the bottom end of the 104 and the second inner side wall 106. In addition, the interlocking bone anchor 1 further includes at least one screw 12 having a screw head 122 and a screw post 124. The screw head 122 is connected to the screw post 124. The diameter of the screw head 122 corresponds to The opening diameter of the first inner side wall 104, the second inner side wall 106, and the third inner side wall 108, that is, the screw head 122 is constricted (upper tapered) from top to bottom, wherein the screw head 122 The outer ring is provided with a first threaded portion 1222, and the outer side ring of the screw post 124 is provided with a second threaded portion 1242.
In use, the first internal thread 10442, the second internal thread 1062 and the third internal thread 1082 have the same pitch, lead, outer diameter, inner diameter and thread angle, and the first screw portion The first internal thread 10442, the second internal thread 1062 and the third internal thread 1082 are directly threaded on the inner side of the fourth inner side wall 109. The screw 12 and the bone plate body 10 can be locked to each other through the screwing of the above-mentioned parts, and the screw post 124 is further locked to a bone (not shown), and the third internal screw The tooth 1082 can increase the number of the bolts of the screw head 122 close to one side of the first internal thread 1042, so that the locking force can be improved. Please refer to the sixth figure. In addition to the above, if the fixing hole 102 is disposed on one of the thin edges 100 of the bone plate body 10, if the majority of the first screw portion 1222 is not exposed, the locking is reduced. The force also needs to pass through the third internal thread 1082 on the inner side of the side wall 108 to increase the interlocking fixing force of the first screw portion 1222 and the fixing hole 102.
In addition, referring to FIG. 7 and FIG. 8 together, it is a perspective view of the bone plate of the above embodiment and a perspective exploded view of the bone plate. The overall three-dimensional structure of the fixing hole 102 of the bone plate body 10 can be more clearly seen. As shown in the figure, the bone plate body 10 has a plurality of the fixing holes 102 and a plurality of the screws 12, and when the fixing holes 102 are The first internal thread 1042 is smaller than the second internal thread 1062 (refer to the fourth figure), and the inner side of the side wall 108 is added to interlock the first screw portion 1222 with the fixing hole 102. The force is increased, wherein the sidewall 108 is optimally formed integrally with the bone plate body 10, and the sidewall 108 may be additionally disposed at an extension of the first inner sidewall 104 (refer to FIG. 4). The locking force is increased for the purpose of high safety. In addition, the side wall 108 can be shaped like a moon to cover the screw 12, and the protruding point of the inclined screw can be made more obvious by the third inner side wall 108. It is smooth and improves the comfort of the skin of the affected part due to the smoothness of the bone plate body 10.
The interlocking bone anchor of the present invention is constructed by the above, and when the thin plate body 10 is kept, the side wall 108 is transmitted to strengthen the locking force, so that the bone plate body 10 and the screw 12 can be prevented.
