Abstract
Description
本發明係關於一種骨板組件，特別是關於一種輔助金屬絲固定在骨骼上的骨板組件。 The present invention relates to a bone plate assembly, and more particularly to a bone plate assembly in which an auxiliary wire is fixed to a bone.
臨床上最常用以治療骨折的方法，就是由數個骨釘將一骨板結合定位於骨骼的骨折處；然而，當骨折處發生在接近關節部位時，為顧及鎖入骨釘時可能影響患者關節活動角度的問題，使得骨釘鎖入骨骼的結合角度與位置受到了很大的限制，從而容易無法提供某些骨塊穩定的固定效果，也因此易於術後因活動而導致骨板與骨骼之間產生位移，進而造成新生骨產生歪斜或變形的情況，甚至會造成骨折無法癒合。 The most common method used to treat fractures in clinical practice is to use a bone nail to position a bone plate in the fracture of the bone; however, when the fracture occurs close to the joint, it may affect the joint of the patient in order to take into account the locking of the nail. The problem of the angle of action makes the binding angle and position of the bone nail locked into the bone greatly restricted, so that it is easy to provide a stable fixation effect of certain bone blocks, and thus it is easy to cause bone plate and bone due to activity after surgery. Displacement occurs, which causes the new bone to be skewed or deformed, and even the fracture cannot heal.
目前，骨板是醫學臨床中用來固定人體內的骨骼，以維持骨骼對位的一種器械，現有的骨板通常是在板體上設置鎖定孔、導針孔和加壓孔，通過鎖定孔、導針孔和加壓孔來實現骨折端的連接定位，由於在臨床手術中，主刀醫師要不停的更換手術器械，而且骨板的安裝要與骨體的形狀相匹配，在骨板的安裝過程中要根據患者狀況選擇骨板的角度及其他固定方式如金屬絲或金屬繩索，現有的骨板結構中，由於沒有設置供金屬絲或金屬繩索的預安裝位置，金屬絲或金屬繩索安裝與骨板結合過程中會出現滑落問題。 At present, the bone plate is a device used in medical clinical practice to fix the bone in the human body to maintain the bone alignment. The existing bone plate usually has a locking hole, a guide pin hole and a pressing hole on the plate body, and the locking hole is passed through the locking hole. The needle hole and the pressure hole are used to realize the connection and positioning of the fracture end. In the clinical operation, the surgeon needs to continuously change the surgical instrument, and the bone plate is installed to match the shape of the bone body, and the bone plate is installed. During the process, the angle of the bone plate and other fixing methods such as wire or metal rope should be selected according to the patient's condition. In the existing bone plate structure, the wire or metal rope is installed and installed because there is no pre-installation position for the wire or metal rope. There is a slippage problem during the bone plate bonding process.

Degree, 95 degrees, 100 degrees, 120 degrees, 150 degrees, 175 degrees or 179 degrees, etc., but is not limited thereto. In addition, the screw holes 24 are arranged at equal intervals in a straight line, or the screw holes 24 may be alternately arranged in a staggered manner to improve the locking of the screws 102 on the bone 101. In this embodiment, a width of the body 2 is reduced from a center to the both ends of the body 2, and the body 2 is integrally formed.
依據上述的結構，如第2及3圖所示，在該骨骼101發生骨折之情況時，該骨釘104係藉由一導引器材與一螺合工具(未繪示)相互配合，使該骨釘104固定至該骨骼101的骨折患處，而該骨板組件100的穿孔23即套入該骨釘104上，並且利用該螺栓103穿過該穿孔23，進而與該骨釘104相螺合；接著，將其中一螺絲102穿過該墊附片4的對位孔40並穿過該本體2的螺合孔24而鎖合於該骨骼101上，其他的螺絲102則依序穿過該本體2的螺合孔24而鎖合在該骨骼101上，同時利用該金屬絲105在該骨骼101及骨板組件100外圍進行圈繞綁固，使該金屬絲105卡固在該鎖合面21及墊附片4的接合處，並且卡附在該卡槽20中，以強化該骨板組件100固定在該骨骼101的穩固程度，其中該墊附片4及卡槽20能夠提供該金屬絲105的固定效果，避免該金屬絲105產生滑脫的情形；其中，或者該墊附片4的對位孔40可選擇性的對位該等螺合孔24的其中一個，並不侷限於本發明的第1圖所示，進而使該本體2被固定在該骨骼101的骨折患處，而達到穩固的效果。另外，該鎖合面21遠離該穿孔23的一側形成該斜面211的設計，可用以使該本體2與該 骨骼101固定之前，可方便插入將該本體2插入於該骨骼101與肌肉(未繪示)的間隙內，以利於手術的操作。 According to the above structure, as shown in FIGS. 2 and 3, when the bone 101 is fractured, the bone nail 104 is coupled to a screwing tool (not shown) by a guiding device. The nail 104 is fixed to the fractured part of the bone 101, and the perforation 23 of the bone plate assembly 100 is inserted into the bone nail 104, and the bolt 103 is passed through the through hole 23 to be screwed with the nail 104. Then, one of the screws 102 passes through the alignment hole 40 of the pad attachment piece 4 and passes through the screw hole 24 of the body 2 to be locked to the bone 101, and the other screws 102 sequentially pass through the same. The threaded hole 24 of the body 2 is locked to the bone 101, and the wire 101 is used to entangle the bone 101 and the periphery of the bone plate assembly 100 to secure the wire 105 to the locking surface. The joint of the pad and the pad 4 is attached to the card slot 20 to enhance the stability of the bone plate assembly 100 to the bone 101, wherein the pad piece 4 and the card slot 20 can provide the metal. The fixing effect of the wire 105 avoids the occurrence of slippage of the wire 105; wherein, or the alignment hole 40 of the pad attached piece 4 is selective One of the alignment holes 24 is not limited to the first embodiment of the present invention, and the body 2 is fixed to the fracture site of the bone 101 to achieve a stable effect. In addition, a side of the locking surface 21 away from the through hole 23 forms a design of the inclined surface 211, and the body 2 can be used to Before the bone 101 is fixed, the body 2 can be easily inserted into the gap between the bone 101 and the muscle (not shown) to facilitate the operation of the operation.
如上所述，本發明的骨板組件100利用在該本體2上形成該卡槽20而與金屬絲105相配合固定，使該金屬絲105卡合固定在該墊附片4的一側以及該卡槽20上，而能夠避免該金屬絲105滑脫，藉此強化該本體2透過該骨釘104固定在該骨骼上的位置；另外，透過該墊附片的對位孔對位於相應的螺合孔並以該螺絲102加以固定，可增加該螺絲102的鎖固效果，進而提升該本體2固定在該骨骼101的穩定性。 As described above, the bone plate assembly 100 of the present invention is formed by being fixed to the wire 105 by forming the card slot 20 on the body 2, so that the wire 105 is snap-fitted to one side of the pad attaching piece 4 and The card slot 20 is configured to prevent the wire 105 from slipping off, thereby reinforcing the position of the body 2 fixed to the bone through the bone nail 104; in addition, the alignment hole pair passing through the pad attachment sheet is located at the corresponding screw The hole is fixed and fixed by the screw 102, so that the locking effect of the screw 102 can be increased, thereby improving the stability of the body 2 fixed to the bone 101.
