隨著科技的發達以及人們生活品質提升,對於醫療技術需求日益增加,傳統的醫療器材亦趨多元化與人性化方向發展,相較早期注射器只要求能將藥物注入體內,因此常利用不當的輸送管線材料置入體內,產生許多後遺症,而現代注射器不僅需要安全無毒,更要求無痛精確,傳統經典注射器主要包含活塞桶及針頭,注射過程中透過活塞推送注射液經由中空針筒注入人體,因此,每當醫護人員施行注射都須相當注意注射深度是否到達患部,以及注射位置導致的失血問題以及減輕病患痛覺,稍有不慎即可能產生不必要的傷害。 With the development of science and technology and the improvement of people's quality of life, the demand for medical technology is increasing. Traditional medical equipment is also diversified and humanized. Compared with early syringes, only drugs can be injected into the body, so improper use is often used. The pipeline material is placed in the body, which produces many sequelae. Modern syringes not only need to be safe and non-toxic, but also require painless and precise. Traditional classic syringes mainly contain piston barrels and needles. During the injection process, the injection solution is injected through the hollow syringe into the human body through the piston. Whenever a medical professional performs an injection, he or she must pay considerable attention to whether the depth of the injection reaches the affected part, as well as the blood loss caused by the injection position and alleviate the pain of the patient. Unintentional injury may result in unnecessary injury.
但隨著科技發展日益月新,許多早期技術所遇到的困難都有解決方法,例如,就中國專利技術方面而言,中國發明專利公開第CN104840358A號、中國發明專利公開第CN104287960A號、中國實用新型專利公告第CN204009142U號等,均已揭露利用光纖作為針灸針頭,可輔助定位及能量療法,但並無揭露中空管設計,與注射及抽 吸需求作用不同;另外,在另一件中國發明專利公開第CN103648368A號中,則揭露一種多個腔管的針頭,其中腔管可作為注射藥品及抽吸組織或置入光纖形成光通道,本設計與傳統針頭差別在於腔管並無圓心設計,且光纖導管也並非依附於注射及抽吸管內壁或針頭外側;此外,在中國發明專利公開第CN1241443A號一案中,則揭露一種可輸液光纖針,光纖固定於針座芯,並置於針頭內管,針底座與輸液器相連,當針頭穿刺於血管中,光纖針可伸出針頭實施照射治療,並且具有輸液功能。 However, with the development of science and technology, the difficulties encountered in many early technologies have been solved.

In addition, in another Chinese Patent Publication No. CN103648368A, a needle of a plurality of lumens is disclosed, wherein the lumen can be used as an injection medicine and a suction tissue or an optical fiber to form an optical channel. The difference between the design and the traditional needle is that the lumen has no center design, and the fiber catheter is not attached to the inner wall of the injection and suction tube or the outside of the needle; in addition, in the case of Chinese Patent Publication No. CN1241443A, an infusion can be disclosed. The fiber needle is fixed to the needle core and placed in the inner tube of the needle. The needle base is connected to the infusion set. When the needle is punctured into the blood vessel, the fiber needle can extend out of the needle to perform irradiation treatment, and has an infusion function.

接著,請參考圖2及圖3,其中,圖2係為本發明的光纖注射及抽吸裝置中的針頭注射及抽吸端局部放大示意圖;而圖3係為本發明的光纖注射及抽吸裝置中的針頭剖面示意圖。首先,如圖2所示,本發明的針頭10為長直金屬導管設計,針頭10的針尖110為一圓柱斜面體,針頭10最外層為不鏽鋼針(Stainless Steel)11,例如:使用規格型號為21G的尺寸(內徑為0.5mm;外徑為0.8mm);而包覆在不鏽鋼針11內層為另一不鏽鋼針12,例如:使用規格型號為27G的尺寸(內徑為0.16mm;外徑為0.4mm)。很明顯的,不鏽鋼針12是被包覆在不鏽鋼針11中,並且將不鏽鋼針12外徑的部分圓周面與不鏽鋼針11內徑的部分圓周面黏著成一體。由於,不鏽鋼針11的內徑大於不鏽鋼針12的外徑,故當不鏽鋼針12與不鏽鋼針11的一部份黏著成一體後,會形成兩個通道,即流體通道15與光通道17;其中流體通道15為不鏽鋼針12與不鏽鋼針11之間的間隙(其間隙接近0.1mm),而光通道17就是不鏽鋼針11的內徑(內徑為0.5mm),如圖3的剖面圖所示。根據上述即圖2所示,本發明是將流體通道15作為注射及抽吸液體的通道,而光通道17作為光纖導線的通道。 2 and FIG. 3, wherein FIG. 2 is a partial enlarged view of the needle injection and suction end of the optical fiber injection and suction device of the present invention; and FIG. 3 is the optical fiber injection and suction of the present invention. A schematic view of the needle cross section in the device. First, as shown in FIG. 2, the needle 10 of the present invention is designed as a long straight metal conduit.

It is apparent that the stainless steel needle 12 is coated in the stainless steel needle 11, and a part of the circumferential surface of the outer diameter of the stainless steel needle 12 is adhered to a part of the circumferential surface of the inner diameter of the stainless steel needle 11. Since the inner diameter of the stainless steel needle 11 is larger than the outer diameter of the stainless steel needle 12, when the stainless steel needle 12 is adhered to a part of the stainless steel needle 11, two channels, that is, the fluid passage 15 and the light passage 17 are formed; The fluid passage 15 is a gap between the stainless steel needle 12 and the stainless steel needle 11 (the gap is close to 0.1 mm), and the light passage 17 is the inner diameter of the stainless steel needle 11 (the inner diameter is 0.5 mm), as shown in the cross-sectional view of FIG. . According to the above, which is shown in Fig. 2, the present invention uses the fluid passage 15 as a passage for injecting and sucking liquid, and the optical passage 17 serves as a passage for the optical fiber lead.
此外,如圖3所示,本發明的針頭10的最外一環為不鏽鋼針11,而內環為不鏽鋼針12,並且將不鏽鋼針12與不鏽鋼針11的一部份黏著成一體後,使得不鏽鋼針12的中心點形成一種偏心的結構,藉由此一偏心的結構,使得在不鏽鋼針12與不鏽鋼針11未連接的一部份,形成了流體通道15。另外,在不鏽鋼針11與不鏽鋼針11黏著的一邊,會在適當的位置上,形成一個貫穿不鏽鋼針12與不鏽鋼針11一邊的貫穿孔130,此貫穿孔130即是用來讓光纖導線50進入針頭10的地方。 In addition, as shown in FIG. 3, the outermost ring of the needle 10 of the present invention is a stainless steel needle 11, and the inner ring is a stainless steel needle 12, and the stainless steel needle 12 is adhered to a part of the stainless steel needle 11 to make stainless steel. The center point of the needle 12 forms an eccentric structure whereby an eccentric structure forms a fluid passage 15 in a portion where the stainless steel needle 12 and the stainless steel needle 11 are not connected. Further, on the side where the stainless steel needle 11 and the stainless steel needle 11 are adhered, a through hole 130 penetrating the side of the stainless steel needle 12 and the stainless steel needle 11 is formed at an appropriate position, and the through hole 130 is used to allow the optical fiber lead 50 to enter. The place where the needle 10 is.
請繼續參考圖2及圖3。如圖2所示,由於光通道17是作為光纖導線的通道,而為了避免人體的體液滲入光通道17,造成醫護人員可能被體液汙染;故在本發明的較佳實施例中,會將光通道17在靠近針尖110一端的開口處,充填具有高導光物14,用以封閉光通道17在靠近針尖110一端,以阻絕體液經由光通道17滲出,同時,也藉由此一高導光物14作為光纖導線50延伸進入針頭10的終端。而在本發明的另一較佳實施例中,也可以選擇將光通道17在靠近針尾端120的開口處,也使用高導光物14來封閉光通道17在靠近針端120的一端,除了阻絕注射及抽吸液體滲入光通道17外,也可以在將光纖導線50配置至針頭10內時,兩端都可以作為針尖,方便光纖導線50的組裝。而在本發明中的高導光物14,可以選擇使用一種PMMA的壓克力材料,但本發明並不加以限制。在針頭10靠近針尾端120一側,則形成一個貫穿至光通道17的貫穿孔130,此貫穿孔130可以讓光纖導線50通過,使得光纖導線50可以配置在光通道17中。而在本發明的一個較佳實施例中,高導光物14,可以是透明的材質,當針頭10尖端進入人體後,使人體後,可以將針頭10周圍局部組織的影像光源傳送至外部攝像機成像並顯示,藉此,除了可以提高注射及抽吸位置的準確性外,還可以作為探測裝置,提供醫護人員更精準的判斷針頭10所在的為置,以進一步提注射及抽吸位置的準確性。 Please continue to refer to Figure 2 and Figure 3.
