Abstract
Description
本發明為一種粉末噴灑止血器的技術領域,尤其指一種用於人體且可於噴灑止血粉末之醫療器材。The present invention relates to the technical field of a powder spraying hemostatic device, in particular to a medical device used in the human body and capable of spraying hemostatic powder.
微創手術,是一種最現代及新主流的手術技巧。手術經由幾個微小傷口(約0.5-1.5公分)代替以往一個大傷口的開刀手術,配合先進清晰的內視鏡影像系統,醫師經由影像系統可清楚得知病灶位置,利用精密的機械手臂完成手術。因此手術傷口較小,術後疼痛減少、出血和感染機會也減少。復原時間短而美觀上也大為進步,對病人意義重大。Minimally invasive surgery is one of the most modern and new mainstream surgical techniques. The operation involves several small wounds (approximately 0.5-1.5 cm) instead of the previous large wound operation. With the advanced and clear endoscopic imaging system, the doctor can clearly know the location of the lesion through the imaging system, and the precise robotic arm is used to complete the operation. . Therefore, the surgical wound is smaller, the postoperative pain is reduced, the chance of bleeding and infection is also reduced. The recovery time is short and the aesthetics is also greatly improved, which is of great significance to the patient.
微創手術中雖可利用內視鏡觀察手術狀態,主要仍仰賴使用各式醫療器材進行操作,但手術過程中仍會產生一些無法預測的狀況,例如局部出血不止,此會危及患者生命,也可能造成內視鏡頭被遮蔽,影響手術進行,傳統開放式手術可投放大量止血粉末於出血處,達到快速止血的目的。為此,本發明人思考如何在微創手術中,在狹小的作業空間,利用細小噴管,配合內視鏡使用,在影像導引下,於止血處噴灑止血粉末,覆蓋出血處,達到止血的目的,如此就必須創新研究一組特殊專用的醫療器材。另外此醫療器材之粉末噴管在運作前,必須避免血液進入管內,因為此會導致止血粉末提前於管內與血液作用凝固造成管內阻塞,且也會有污染問題,如何也增加產品設計上的難度。Although endoscopy can be used in minimally invasive surgery to observe the status of the operation, it still relies mainly on the use of various medical equipment for operation, but there are still some unpredictable conditions during the operation, such as local bleeding, which will endanger the life of the patient. It may cause the endoscopic lens to be blocked and affect the operation. In traditional open surgery, a large amount of hemostatic powder can be put on the bleeding site to achieve the purpose of rapid hemostasis. For this reason, the inventor thinks about how to use a small nozzle in a small working space in a minimally invasive surgery to cooperate with an endoscope. Under the guidance of the image, hemostatic powder is sprayed on the hemostatic area to cover the bleeding area and achieve hemostasis. The purpose of this, so it is necessary to innovate and research a group of special dedicated medical equipment. In addition, the powder nozzle of this medical device must prevent blood from entering the tube before it is operated, because this will cause the hemostatic powder to coagulate in the tube in advance and the blood will coagulate in the tube, and there will also be pollution problems. How to increase the product design Difficulty.
為解決上述之問題,本發明之主要目的是提供一種粉末噴灑止血器,主要是利用氣體送進粉末,配合本發明採用的特殊氣流控制方式,在未噴出止血粉末前,維持小流量的氣流,保持管路暢通及防止血液進入。欲使用時再切換迴路送入大量間歇氣體推送止血粉末,精確讓止血粉末覆蓋出血處,以達止血之目的。In order to solve the above-mentioned problems, the main purpose of the present invention is to provide a powder spraying hemostatic device, which mainly uses gas to feed the powder, and cooperates with the special air flow control method adopted by the present invention to maintain a small flow of air flow before spraying the hemostatic powder. Keep the pipeline unobstructed and prevent blood from entering. When you want to use it, switch the loop and send a large amount of intermittent gas to push the hemostatic powder, so that the hemostatic powder can cover the bleeding site accurately to achieve the purpose of hemostasis.
為達上述之目的,本發明粉末噴灑止血器包括醫療級氣體產生器、氣體輸送控制器、粉末容器及粉末輸送管。醫療級氣體產生器設有主供氣管輸出氣體。氣體輸送控制器設有第一供氣管及第二供氣管,主供氣管連接於氣體輸送控制器。氣體輸送控制器控制第一供氣管與第二供氣管的供氣時機及流量。粉末容器設有容器接頭、單向供氣止逆閥、腔體,腔體內為止血粉末設置區域,單向供氣止逆閥位於腔體內且緊鄰容器接頭,前述第一供氣管連接於容器接頭,適時供氣至粉末容器內;粉末輸送管串接於粉末容器出口端,粉末輸送管內部具有一粉末通道,管壁另設有供氣歧管與粉末通道相通,第二供氣管連接於供氣歧管。粉末輸送管未端設有粉末噴出管。To achieve the above purpose, the powder spraying hemostatic device of the present invention includes a medical-grade gas generator, a gas delivery controller, a powder container and a powder delivery tube.

如圖1及圖2所示,分別為本發明粉末噴灑止血器之立體圖及平面示意圖。本發明粉末噴灑止血器包括一醫療級氣體產生器1、一氣體輸送控制器2、一粉末容器3、以及一粉末輸送管4。醫療級氣體產生器1負責輸出氣體,經氣體輸送控制器2切換氣體送至粉末容器3及粉末輸送管4的時機。在尚未需供給粉末時,提供小流量氣體先經粉末輸送管4送出,維持管路暢通且避免血液回流。之後欲噴出粉末時,再供給大量氣體且將氣流切換至粉末容器3、經粉末輸送管4噴出粉末,使止血處被止血粉末所覆蓋,達到快速止血的目的。As shown in Figure 1 and Figure 2, respectively are a three-dimensional view and a schematic plan view of the powder spraying hemostatic device of the present invention. The powder spraying hemostatic device of the present invention includes a medical
接著就本發明各構件的結構作一詳細的說明:Then make a detailed description of the structure of each component of the present invention:
醫療級氣體產生器1為一空氣壓縮機內含醫療級過濾器,設有一主供氣管11讓產生的氣體輸出。The medical-
氣體輸送控制器2為一氣流切換用電子控制閥,主供氣管11連接於此。氣體輸送控制器2另設有第一供氣管21及第二供氣管22作為氣體的輸出管。氣體輸送控制器2控制第一供氣管21與第二供氣管22的供氣時機及流量。在本實施例中,氣體輸送控制器2在同一個時間中僅使第一供氣管21或第二供氣管22兩者其中之一供氣。第一供氣管21末端連接於粉末容器3,負責能供大流量的氣體,利用氣體將粉末容器3內的止血粉末5送出。第二供氣管22連接於粉末噴出管4側壁,此管主要提供小流量的氣體,維持管路的暢通。The
該粉末容器3為一長條狀的中空管件,由上而下分別為容器接頭31、單向供氣閥32、腔體33。該容器接頭31具有一大尺寸凸環311,此凸環311可在使用時利用其他機構或支架固定粉末容器3的位罝,使該粉末容器3呈直立狀或斜一角度狀。該腔體33內形成一腔室,此為止血粉末5的設置區域。腔體33為透明殼體,可在運作時立即觀察止血粉末是否噴出。止血粉末5並不限醫藥用品,也可為醫材、植物或食物粉末等,只要具有能在出血處提升止血之乾燥粉末皆可。單向供氣止逆閥32設於腔體33內位置緊鄰容器接頭31。單向供氣止逆閥32僅讓氣體由容器接頭31進入腔體33內,避免氣流切換時止血粉末5逆流至第一供氣管21內。腔體33出口是串接於粉末輸出管4。The
粉末輸送管4為三方向的T型分流管。該粉末輸送管4內部具有一粉末通道41,管壁另設有供氣歧管42與該粉末通道41相通。該粉末通道41入口是連通於粉末容器3內的腔室,出口位於 粉末輸送管4末端再設有一粉末噴出管43。該粉末噴出管43為一細長小管徑的管件,以利在手術中伸入體內的止血處。該止血粉末5的顆粒須小於粉末噴出管43管內徑30%,以利氣體能推送止血粉末5經狹長小管徑的粉末噴出管43噴出。該第二供氣管22是連接於該供氣歧管42處 。The
接著就本發明實際的運作流程作一詳細的說明:Next, a detailed description will be given of the actual operation process of the present invention:
在手術過程中,可配合內視鏡的操作將粉末噴出管43末端導引至出血處,在導引放置的過程中或等待運作的狀態下,如圖3所示,醫療級氣體產生器1持續產生氣體,經氣體輸送控制器2切換且提供小流量氣體經第二供氣管22、粉末輸出管4、粉末噴出管43送出,此小流量氣體,可維持粉末噴出管43暢通,避免異物或血液侵入粉末噴出管43內。During the operation, the end of the
如圖4所示,欲於出血處噴出粉末時,由氣體輸送控制器2進行切換,停止第二供氣管22的供氣,改由供給該第一供氣管21大量的氣體,而此方式可採間歇式大量氣體供氣,讓氣體通過粉末容器3內的單向供氣閥32,推送腔體33內的止血粉末5進入粉末輸送管4的粉末通道41內,最後經該粉末噴出管43於出血處噴出止血粉末5。其中該單向供氣止逆閥32可防止氣體停止時氣體及粉末產生逆流,避免粉末污染。另外本發明採用間歇的氣體可避免氣體因連續噴出時,粉末因架橋現象出現只噴出氣體不出粉末的現象,且氣體間歇動作也會減少粉末因過度飛揚的現象而影響附著效果。另外粉末容器3可呈直立狀設置,以利粉末有效地噴出。如此使本發明能滿足使用內視鏡,體腔內手術如腸胃道手術、或泌尿道手術中或腫瘤治療,可能需要快速止血的目的。As shown in Figure 4, when powder is to be sprayed from the bleeding area, the
