Description
本發明係關於一種截骨手術器械,更明確地說,係關於一種用於執行截骨手術,且為受術者量身訂製的截骨手術器械。 The present invention relates to an osteotomy surgical instrument, and more particularly to an osteotomy surgical instrument for performing an osteotomy procedure and tailored to the subject.
膝蓋是人體中承受力量最大的關節之一,一般人若是膝蓋曾有過運動傷害,或是步入中年階段,都有可能造成關節面的軟骨磨損,產生膝關節疼痛的症狀,導致生活日常功能的活動度受減。這就是退化性關節炎的成因。 The knee is one of the most powerful joints in the human body. If a person has had sports injuries on his knees or enters the middle age stage, it may cause cartilage wear on the articular surface, causing symptoms of knee pain, leading to daily life functions. The activity is reduced. This is the cause of degenerative arthritis.
過去的習知治療方法,係以植入人工關節來替換原有的膝關節。但是為了植入人工關節需要大量切除股骨、脛骨與髕骨等的關節面,來提供金屬與高分子植入物的固定。但由於植入物磨耗的緣故,此類全人工膝關節置換手術的有效使用期,最多為二十年,但常會併發手術後的感染、骨溶解與骨疏鬆問題,因而導致有可能必須再進行二次手術。再者,部分退化性關節炎的初期患者,其實僅內側關節面的軟骨磨損,並非有必要使用全人工關節置換,來將所有膝關節面切除。所以對於初期僅內側退化性關節炎患者,通常會施行高位脛骨截骨手術(HIGH TIBIAL OSTEOTOMY)。 In the past, the conventional treatment method was to replace the original knee joint with an artificial joint. However, in order to implant an artificial joint, it is necessary to remove a large number of articular surfaces such as the femur, the tibia and the tibia to provide fixation of the metal and the polymer implant. However, due to the wear of the implant, the effective use period of this type of total artificial knee replacement surgery is up to 20 years, but often the infection, osteolysis and osteoporosis problems after the operation, which may lead to the need for further Second surgery. Furthermore, in the initial stage of some patients with degenerative arthritis, only the cartilage of the medial articular surface is worn, and it is not necessary to use total artificial joint replacement to remove all knee articular surfaces. Therefore, for patients with only medial degenerative arthritis in the early stage, high-level tibia osteotomy (HIGH TIBIAL OSTEOTOMY) is usually performed.
高位脛骨截骨手術(HIGH TIBIAL OSTEOTOMY)係在患者的脛骨靠近膝蓋的內側上端開一道截口,再把截口撐開填入人造補骨後,同時以骨板與骨釘固定。藉此來矯正患者膝關節內翻的生物力學軸線。由於僅只在脛骨內側近端進行骨頭切開與角度調整,因此不會有任何骨質的大量移除,對於內側關節面軟骨所引起的膝關節疼痛患者,是很好的手術治療方式之一。 HIGH TIBIAL OSTEOTOMY is a kerf in the upper end of the patient's tibia near the knee, and then the ostium is opened and filled into the artificial bone, and the bone plate and the nail are fixed. Thereby to correct the biomechanical axis of the patient's knee varus. Since the bone incision and angle adjustment are only performed at the proximal end of the medial aspect of the humerus, there is no substantial removal of any bone mass, and it is one of the good surgical treatment methods for patients with knee joint pain caused by the medial articular surface cartilage.
不過,因為高位脛骨截骨手術需要將脛骨近端切出一道開口,其切入的位置、角度、深度與撐開高度等程序,皆需要在術前進行審慎評估。目前在進行本手術時,臨床醫師常只能藉由X光機的協助,再加上其個人的判斷,來決定上述截骨撐開的幾何參數。但每位退化性關節炎患者膝關節內翻的生物力學軸線狀況不一,上述的手術參數也是每個患者皆不同。考慮到上述個人膝關節內翻的生物力學軸線的不一狀況,在手術器械的設計上也必須將個人差異一併考量。 However, because the high tibial osteotomy requires cutting the proximal end of the humerus, procedures such as the location, angle, depth, and height of the iliac crest need to be carefully evaluated before surgery. At the time of the operation, clinicians often only rely on the assistance of the X-ray machine, coupled with their personal judgment, to determine the geometric parameters of the osteotomy. However, the biomechanical axis of knee varus varies from patient to degenerative arthritis, and the above surgical parameters are different for each patient. In view of the different conditions of the biomechanical axis of the above-mentioned individual knee varus, individual differences must also be considered in the design of surgical instruments.
