Description
本發明是一種骨骼植入物,該骨骼植入物係屬於生物體植入或固定用物體,用以植入於生物骨骼之植入物。本發明的骨骼植入物特別指一種具有光滑處理面與粗糙處理面之構件結合面的骨骼植入物。The present invention is a bone implant that is an implant or fixation object for implantation into an implant of a biological bone. The bone implant of the present invention particularly refers to a bone implant having a component interface of a smooth treated surface and a rough treated surface.
隨著科技的日益發達,醫學技術也隨之蓬勃進展,縱使病患在原有生物體損壞後,亦可藉由一種人造件的置換技術取代原有生物體的機能,實為病患之一大福音,惟,先前的技術中所使用的植入物往往設計不周全。With the development of science and technology, medical technology has also prospered. Even if the patient is damaged by the original organism, the function of the original organism can be replaced by a replacement technique of artificial parts. Gospel, however, implants used in previous techniques are often not well designed.
如圖六所示,顯示了一種目前習用三件式骨骼植入物8,下方為植入基體810,中間為連接體820,上方另有一輔助連接件830。該輔助連接件830穿過連接體820,並插入植入基體810之內部。該輔助連接件830之前端部份設有外螺紋,植入基體810之內部設有內螺紋,藉此將該輔助連接件830、連接體820及植入基體810鎖固在一起。As shown in Fig. 6, a conventional three-piece bone implant 8 is shown, with an implant base 810 underneath, a connector 820 in the middle, and an auxiliary connector 830 on top. The auxiliary connector 830 passes through the connector 820 and is inserted into the interior of the implant base 810. The front end portion of the auxiliary connecting member 830 is provided with an external thread, and the inside of the implanting base 810 is internally threaded, thereby locking the auxiliary connecting member 830, the connecting body 820 and the implanting base 810 together.
圖七為圖六之三件式骨骼植入物分解狀態之剖面示意圖,該植入基體810與連接體820之結合面並非較穩固的接觸面,該連接體820與輔助連接件830間並非較穩固的接觸面,結合面更多且無法密合,經過長時間的使用則更容易使細菌侵入骨骼植入物而腐壞變形,且其植入基體810與連接體820之間及連接體820與輔助連接件830之間均無較穩固的結合面,經過長時間的使用容易滑動鬆脫,穩定性不佳。7 is a schematic cross-sectional view showing the exploded state of the three-piece bone implant of FIG. 6. The joint surface of the implant base 810 and the connecting body 820 is not a relatively stable contact surface, and the connecting body 820 and the auxiliary connecting member 830 are not The stable contact surface has more bonding surfaces and can not be closely adhered. After a long time of use, the bacteria are more likely to invade the bone implant and spoil and deform, and the implanted base 810 and the connecting body 820 and the connecting body 820 are connected. There is no relatively stable joint surface with the auxiliary connecting member 830, and it is easy to slide and loose after a long time of use, and the stability is not good.
如圖八所示,顯示了一種目前習用二件式的骨骼植入物7,下方為植入基體710,上方為連接體720。二件式的骨骼植入物7仍須藉由將一輔助固定件(圖未示)穿過連接體720,並插入植入基體710之內部。該輔助固定件之前端部份設有外螺紋(圖未示),植入基體710之內部設有內螺紋(圖未示),藉此將該輔助固定件、連接體720及植入基體710鎖固在一起。該植入基體710與連接體720之結合面並非較穩固的接觸面,結合面無法密合,經過長時間的使用,容易使細菌侵入骨骼植入物而腐壞變形,且其植入基體710與連接體720之間無較穩固的結合面,經過長時間的使用容易滑動鬆脫,穩定性不佳。As shown in Fig. 8, a two-piece bone implant 7 is shown, with an implant base 710 underneath and a connector 720 on top. The two-piece bone implant 7 still has to be inserted into the interior of the implant base 710 by passing an auxiliary fastener (not shown) through the connector 720. The front end portion of the auxiliary fixing member is provided with an external thread (not shown), and the inside of the implant base 710 is internally threaded (not shown), whereby the auxiliary fixing member, the connecting body 720 and the implanting base 710 are provided. Lock together. The bonding surface of the implanting substrate 710 and the connecting body 720 is not a relatively stable contact surface, and the bonding surface cannot be closely adhered. After a long period of use, the bacteria are easily invaded into the bone implant and spoiled and deformed, and the substrate 710 is implanted. There is no relatively stable joint surface with the connecting body 720, and it is easy to slide and loose after a long time of use, and the stability is not good.
如圖九所示,顯示了另一種目前習用的骨骼植入物9,其植入基體910與連接體920之間的結合面,雖另施以黏著劑940,但經過長時間的使用仍然造成滑動而鬆脫,該骨骼植入物9構件間仍無法有效緊密結合。As shown in FIG. 9, another currently used bone implant 9 is shown, which is implanted between the base 910 and the connecting body 920. Although an adhesive 940 is additionally applied, it is still caused by prolonged use. Sliding and loose, the bone implant 9 components are still unable to effectively bind tightly.
由以上習知技術之缺點,可知其骨骼植入物間的「結合面」,實具有許多待改進的空間,而藉由多年從事相關產業之研發與製造經驗,針對上述現有技術所面臨的問題加以探討研究,並積極的尋找解決之方法,經多次測試及改良後,終於創造出一種可確實改進上述缺失之骨骼植入物。From the shortcomings of the above-mentioned prior art, it can be known that the "joining surface" between the bone implants has many spaces to be improved, and the problems faced by the above-mentioned prior art are solved by years of experience in research and development and manufacturing of related industries.
