Description
本創作係有關於一種骨釘結構，尤指針對一種具有複數切削槽之骨釘結構。 The present invention relates to a bone nail structure, in particular to a bone nail structure having a plurality of cutting grooves.
成人骨頭共有206塊，分為頭顱骨、軀幹骨、上肢骨、下肢骨四個部分。它們分佈在全身各部位，人體的骨頭具有支撐身體的作用，保護內部器官，而身體能夠做出各式各樣的姿勢與動作，大致是靠著骨頭、肌肉與各種關節的相互配合來達成。 There are 206 adult bones, which are divided into four parts: skull, trunk bone, upper limb bone and lower limb bone. They are distributed throughout the body. The bones of the human body support the body and protect the internal organs. The body can make a variety of postures and movements, which are basically achieved by the cooperation of bones, muscles and various joints.
人體所有的骨頭，從形狀和大小上各不相同，有的較大，如脛骨、肱骨等，有的則很小，如趾骨等。從形狀上大致可分為5種：長骨、短骨、扁平骨、不規則骨和含氣骨。 All the bones of the human body vary in shape and size, and some are large, such as the humerus and the tibia, while others are small, such as the phalanx. There are roughly five types of shapes: long bones, short bones, flat bones, irregular bones, and gas-containing bones.
而上述人體之骨頭於骨折時，其治療方法可利用開放復位內固定術，開放復位內固定術是切開患處的皮膚及肌肉等軟組織以暴露骨頭，在直視下進行整復骨折、脫位的手術。在開放復位的同時，把內固定器材安裝在患者體內，以固定骨折端者稱內固定術。再根據骨折的不同部位，可採用相適合的內固定方式，按具體需要，選擇相應的內固定器材，如不銹鋼絲、螺絲釘、骨圓針、鋼板、髓內針(釘)等。 When the bones of the above-mentioned human body are fractured, the treatment method can be performed by open reduction internal fixation, and the open reduction internal fixation is to open the soft tissue of the skin and muscles of the affected area to expose the bone, and perform the operation of repairing the fracture and dislocation under direct vision. At the same time of open reduction, the internal fixation equipment is installed in the patient's body, and the internal fixation is called to fix the fracture end. According to different parts of the fracture, suitable internal fixation can be adopted. According to specific needs, the corresponding internal fixation equipment, such as stainless steel wire, screw, bone round needle, steel plate, intramedullary nail (nail), etc., can be selected.
針對上述之內固定器材，其中螺絲釘係利用外觀上則是呈圓筒形，其表面刻有凹凸的溝稱為螺紋。此螺紋是一個環繞螺絲側面的 螺旋傾斜面，讓螺絲可應用螺旋機制緊鎖著於骨頭上。 In the above-mentioned internal fixed device, the screw is cylindrical in appearance, and the groove having the uneven surface on the surface is called a thread. This thread is a side of the surrounding screw The spiral inclined surface allows the screw to be locked to the bone using a screw mechanism.
習知骨釘結構僅對於骨釘前尖端結構上設有複數個切削槽，且習知骨釘結構其於骨釘本體也為整體直徑相同一致或為骨釘本體之直徑往該尖端慢慢遞減，其不具有刺激骨骼生長之結構。 The conventional nail structure only has a plurality of cutting grooves on the front tip structure of the nail, and the conventional bone nail structure also has the same overall diameter on the bone nail body or slowly decreases toward the tip of the bone nail body. It does not have a structure that stimulates bone growth.
故，本創作針對以上習知技術之缺點做進一步之改良，本創作為一種具有複數切削槽之骨釘，其係利用於該骨釘結構具有複數個切削槽，且該骨釘結構之螺紋部下端部分直徑較為上端螺紋部還大，係先以較粗之螺紋結構穿設於骨頭中，再穿設較細之螺紋部，此種骨釘結構設置於骨骼內時，於該螺紋部會產生間隙，用於晃動該骨釘結構以刺激骨骼生長。此為一種具有進步性及新穎性之創作。 Therefore, the present invention further improves the shortcomings of the above conventional techniques. The present invention is a bone nail having a plurality of cutting grooves, wherein the bone nail structure has a plurality of cutting grooves, and the thread portion of the bone nail structure The lower end portion has a larger diameter than the upper end thread portion, and is firstly threaded in the bone with a thicker thread structure, and then a thin thread portion is formed. When the bone nail structure is disposed in the bone, the thread portion is generated. A gap for swaying the bone nail structure to stimulate bone growth. This is a progressive and novel creation.
