Description
本創作是與可重複使用之手術器械有關，更詳而言之，是關於具有相對運動部件之手術器械(例如手術剪及鑷)，本創作於該類手術器械的工作部位以強化鍍層進行表面改質。This creation is related to reusable surgical instruments, and more specifically to surgical instruments (such as surgical scissors and sputum) with relatively moving parts. This work is performed on the working surface of such surgical instruments with a reinforced coating. Upgraded.
手術器械之表面光滑度與硬度會影響操作性，若以光滑度與硬度等物理特性不佳的手術器械進行手術，很可能面臨人體手術剪切部位劣質化的問題，面臨這類問題時就需要更換新器械。The surface smoothness and hardness of the surgical instrument will affect the operability. If the surgical instrument with poor physical properties such as smoothness and hardness is operated, it is likely to face the problem of poor quality of the surgical shearing part of the human body. Replace with new equipment.
選擇適合之材料被覆於手術器械表面，可增加器械表面之硬度、光滑度和抗腐蝕能力。如中華民國新型專利M322806案，該案提出在手術刀的刀刃部以化學氣相蒸鍍法或物理氣相蒸鍍法生成奈米鑽石薄膜或類鑽石碳膜。由於這一類的薄膜具有良好生物相容性、化學穩定性、且摩擦係數小、硬度高、耐磨損，因此鑽石膜鍍在手術刀的表面，增加了手術刀的使用壽命及性能。Choosing the right material to cover the surface of the surgical instrument increases the hardness, smoothness and corrosion resistance of the surface of the device. For example, in the case of the new patent of the Republic of China, M322806, the case proposed to produce a nano-diamond film or a diamond-like carbon film by chemical vapor deposition or physical vapor deposition at the blade edge of the scalpel. Because this type of film has good biocompatibility, chemical stability, and low friction coefficient, high hardness and wear resistance, the diamond film is plated on the surface of the scalpel, which increases the service life and performance of the scalpel.
目前，手術刀片多為用後即丟的拋棄式，上述專利案的技術若實現在拋棄式刀片上可能較不符合經濟效益。且上述專利技術是實現在手術刀件，手術刀件主要針對手術部位的組織切割，手術刀與組織的相對關係如同硬物質對應軟物質，軟物質受硬物質的力作用而被分割，但軟物質(即 組織)並沒有對硬物質(即手術刀)發生反作用力或者是磨擦力，因此手術刀的上的鍍膜密度及膜厚度不需太高，故採用物理或化學蒸鍍法即可實現。At present, the surgical blades are mostly discarded after use, and the technology of the above patents may be less economical if implemented on a disposable blade. And the above patented technology is realized in the scalpel, the scalpel is mainly for the tissue cutting of the surgical site, the relative relationship between the scalpel and the tissue is like the soft substance corresponding to the soft substance, the soft substance is divided by the force of the hard substance, but soft Substance The tissue does not have a reaction force or a frictional force on the hard substance (ie, the scalpel), so the coating density and film thickness on the scalpel need not be too high, so physical or chemical vapor deposition can be used.
但對於手術剪或手術鑷而言就有所不同了，因為手術剪或手術鑷除了對軟組織施力之外，手術剪之操作還涉及了兩個剪片之間的反覆磨擦，而手術鑷在夾取軟組織時，兩個鑷端彼此承受相對的反作用力及磨擦力，這些都會造成手術剪或手術鑷的工作端提早磨耗。而目前手術剪或鑷極少採用拋棄式，多需要重複消毒及再使用，因此實現在手術剪或鑷的鍍膜密度及厚度即必需因應重複消毒及再使用的過程，並且，手術剪或鑷的總體面積大，若是採取全面性鍍膜是不經濟的，因此必需控制鍍膜的位置。However, it is different for surgical scissors or surgical fistulas. Because surgical scissors or surgery remove the force on the soft tissue, the operation of the surgical scissors involves repeated friction between the two clips. When the soft tissue is gripped, the two ends end with each other with relative reaction and friction, which will cause the working end of the surgical scissors or surgical sputum to wear early. At present, surgical scissors or sputum are rarely disposable, and more need to be repeatedly sterilized and reused. Therefore, the density and thickness of the coating on the surgical scissors or sputum must be repeated for disinfection and reuse, and the overall surgical scissors or sputum The area is large, and it is uneconomical to adopt a comprehensive coating, so it is necessary to control the position of the coating.
本創作之目的是在提供一種強化鍍層表面改質手術器械，所述的手術器械在本創作中是指具有相對運動部件且可重複消毒及再使用之手術器械，例如手術剪及手術鑷。本創作在這一類手術器械的工作部位(例如手術剪的刃部及背部，手術鑷的兩個鑷端)經由化學濺鍍法生成一高膜質密度的強化鍍層，該強化鍍層為類鑽石薄膜或類鑽石改質薄膜，強化鍍層的厚度為0.1~5μm，據此強化手術器械之工作部位的化學穩定性、銳利度、硬度、平滑度、抗磨耗性、生物相容性、可反覆清洗及消毒，並增加了手術剪及鑷的使用壽命。The purpose of this creation is to provide a reinforced coated surface modified surgical instrument, which in the present context refers to surgical instruments having relatively moving parts that can be repeatedly sterilized and reused, such as surgical scissors and surgical sputum. This work creates a high-density density-enhanced coating on the working parts of this type of surgical instrument (such as the blade and back of the surgical scissors, the two ends of the surgical file) by chemical sputtering, which is a diamond-like film or Diamond-like modified film, the thickness of the strengthened coating is 0.1~5μm, which strengthens the chemical stability, sharpness, hardness, smoothness, abrasion resistance, biocompatibility, reversible cleaning and disinfection of the working part of the surgical instrument. And increased the service life of surgical scissors and sputum.
化學濺鍍法生成類鑽石薄膜之技術可應用在以各種金屬材料製成之上述手術器械。強化鍍層除了披覆於手術器械的工作部位之外，也可披覆於整個手術器械的表面。The technique of chemically sputtering to produce a diamond-like film can be applied to the above surgical instruments made of various metal materials. The reinforced coating can be applied to the surface of the entire surgical instrument in addition to the working part of the surgical instrument.
本創作達成上述目的之強化鍍層表面改質手術器械，主要在一 具有相對運動部件的手術器械之工作部位披覆一經由化學濺鍍所生成之強化鍍層，該強化鍍層的厚度為0.1~5μm。該手術器械為手術剪及手術鑷，該工作部位是指該手術剪的兩個刃部及背部，以及該手術鑷的兩個鑷端。This invention aims to achieve the above-mentioned purpose of strengthening the surface modification of surgical instruments, mainly in one The working portion of the surgical instrument having the relatively moving member is coated with a reinforced coating formed by chemical sputtering having a thickness of 0.1 to 5 μm. The surgical instrument is a surgical scissors and a surgical file, and the working site refers to the two blades and the back of the surgical scissors, and the two ends of the surgical file.

為便於說明本案於上述新型內容一欄中所表示的中心思想，茲以具體實施例表達。實施例中各種不同物件係按適於說明之比例、尺寸、變形量或位移量而描繪，而非按實際元件的比例予以繪製，合先敘明。且以下的說明中，類似的元件是以相同的編號來表示。In order to facilitate the description of the central idea of the present invention in the column of the above novel content, it is expressed by a specific embodiment. Various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual elements, as set forth above. In the following description, like elements are denoted by the same reference numerals.
如第一圖至第四圖，實現本創作強化鍍層表面改質之手術器械是指具有相對運動部件且可重複消毒及再使用的，本創作是以手術剪10及手術鑷20為實施例。As shown in the first to fourth figures, the surgical instrument for realizing the surface modification of the enhanced plating of the present invention refers to a relatively movable part and can be repeatedly sterilized and reused. The present invention is an embodiment in which the surgical scissors 10 and the surgical file 20 are used.
第一圖及第二圖是描述該手術剪10於工作部位11經由化學濺鍍法生成一高膜質密度的強化鍍層12。所述的工作部位11是指手術剪10的二剪葉13,14之刃部15及背部16。該強化鍍層12為類鑽石薄膜或類鑽石改質薄膜。薄膜厚度為0.1~5μm。The first and second figures depict a stencil 12 in which the surgical scissors 10 produces a high film density via chemical sputtering at the working site 11. The working portion 11 refers to the blade portion 15 and the back portion 16 of the two blades 13 and 14 of the surgical scissors 10. The reinforced coating 12 is a diamond-like film or a diamond-like modified film. The film thickness is 0.1 to 5 μm.
第三圖及第四圖是描述該手術鑷20於工作部位21經由化學濺鍍法生成一高膜質密度的強化鍍層22。所述的工作部位21是指手術鑷的兩個鑷端23,24。薄膜厚度為0.1~5μm。The third and fourth figures depict the enhanced plating 22 of the surgical file 20 at the working site 21 to produce a high film density via chemical sputtering. The working site 21 refers to the two ends 23, 24 of the surgical file. The film thickness is 0.1 to 5 μm.
化學濺鍍法是一習知技術，且非本創作之專利重點，在此不予贅述。本創作採用化學濺鍍法對上述手術器械進行局部濺鍍，使強化鍍層12,22形成於手術器械的工作部位11,21，可節省濺鍍時間以及濺鍍成本；更重要的是，在手術器械的工作部位披覆強化鍍層12,22，據此強化手術器械之工作部位的化學穩定性、銳利度、硬度、平滑度、抗磨耗性、生物相容性、可反覆清洗及消毒，並增加了手術剪及鑷的使用壽命。The chemical sputtering method is a conventional technique and is not a patent focus of the present invention and will not be described herein. This creation uses chemical sputtering to locally sputter the surgical instruments, so that the reinforced coatings 12, 22 are formed on the working parts of the surgical instruments 11, 21, which can save the sputtering time and the cost of sputtering; more importantly, in the surgery The working part of the device is covered with a reinforced coating 12, 22, thereby enhancing the chemical stability, sharpness, hardness, smoothness, abrasion resistance, biocompatibility, reversible cleaning and disinfection of the working part of the surgical instrument, and increasing The service life of the surgical scissors and sputum.
特別是手術剪10與手術鑷20，它們都是具有相對運動部件的手術器械。手術剪10的兩個剪葉13,14透過相對運動形成的剪力剪斷手術部位的組織，它的刃部15除了剪切組織之外，也另外承受相對運動之磨擦力，所以它的磨耗率會比一般手術刀片為高；而手術鑷20在夾取組織時，兩個鑷端23,24亦承受彼此相對的反作用力及磨擦力，磨耗率也會比一般手術刀片為高，因此本創作特別在手術剪10的刃部15、背部16以及手術鑷20的兩個鑷端23,24披覆強化鍍層，以進行表面改質，從而達到上述的功效。In particular, the surgical scissors 10 and the surgical file 20 are surgical instruments having relatively moving parts. The two shear leaves 13, 14 of the surgical scissors 10 cut the tissue of the surgical site through the shear force formed by the relative motion, and the blade portion 15 is subjected to the relative motion friction force in addition to the shearing tissue, so that it is worn. The rate will be higher than that of the general surgical blade; while the surgical file 20 is gripping the tissue, the two ends 23, 24 are also subjected to opposite reaction forces and frictional forces, and the wear rate is higher than that of the general surgical blade, so In particular, the blade 15 of the surgical scissors 10, the back 16 and the two ends 23, 24 of the surgical file 20 are coated with a reinforced coating for surface modification to achieve the above-mentioned effects.
此外，本創作是以化學濺鍍法於手術器械的局部表面披覆強化鍍層，已知利用化學濺鍍法所生成的強化鍍層，它與手術器械的表面可產生強鍵結性，此鍵結性較一般蒸鍍法所形成之強化鍍層為強，因此本創作之手術器械可經反覆的消毒及使用。再者，本創作強化鍍膜的厚度為薄膜厚度為0.1~5μm，此厚度可再提昇薄膜的物理性能和機械性能，但不影響手術器械之運動及操作。In addition, the present invention uses a chemical sputtering method to coat the surface of the surgical instrument with a reinforced coating. It is known that the reinforced coating formed by the chemical sputtering method can produce strong bonding with the surface of the surgical instrument. The reinforced coating formed by the general vapor deposition method is stronger, so the surgical instrument of the present invention can be repeatedly disinfected and used. Furthermore, the thickness of the enhanced coating of the present invention is 0.1 to 5 μm, which can further improve the physical properties and mechanical properties of the film, but does not affect the movement and operation of the surgical instrument.
強化鍍層除了披覆於手術器械的工作部位之外，也可披覆於整個手術器械的表面。The reinforced coating can be applied to the surface of the entire surgical instrument in addition to the working part of the surgical instrument.
