Description
本發明是有關於一種內視鏡，特別是指一種較易於操作的內視鏡之膨脹氣囊擴張裝置。 The present invention relates to an endoscope, and more particularly to an inflated balloon expansion device of an easier-to-operate endoscope.
消化道阻塞或消化道狹窄會造成吞嚥困難及種種消化道阻塞的症狀。形成消化道阻塞及消化道狹窄的原因包括先天性食道閉鎖、誤吞入強酸或強鹼等化學藥劑使食道內黏膜灼傷、食道本身或食道周圍的腫瘤造成壓迫阻塞、逆流性食道炎，及食道括約肌失去功能產生食道弛緩不全，慢性消化性潰瘍、腫瘤癌症等。食道阻塞及食道狹窄的患者通常無法正常經口進食，需依賴管灌飲食，導致生活品質低落。而目前較為普遍之治療方式為食道擴張術，相較於食道切除手術，食道擴張術的手術風險較低、可降低發生併發症的機率，且能大幅降低患者的疼痛感及不適感。食道擴張術通常使用一擴張器來撐開一食道的一狹窄處，以達成食道擴張的目的。 Obstruction of the digestive tract or narrowing of the digestive tract can cause difficulty in swallowing and obstruction of various digestive tracts. Causes of gastrointestinal obstruction and digestive tract stenosis include congenital esophageal atresia, accidental ingestion of strong acid or alkali and other chemical agents to cause mucosal burns in the esophagus, compression of the esophagus itself or tumor around the esophagus, reflux esophagitis, and esophagus The sphincter loses function to produce esophageal achalasia, chronic peptic ulcer, tumor cancer, and the like. Patients with obstruction of the esophagus and stenosis of the esophagus are usually unable to eat normally by mouth, and need to rely on tube-drinking diet, resulting in low quality of life. At present, the more common treatment method is esophageal dilatation. Compared with esophagectomy, the risk of surgery for esophageal dilatation is lower, which can reduce the chance of complications, and can greatly reduce the pain and discomfort of patients. Esophageal dilation usually uses a dilator to open a narrow space in an esophagus for the purpose of esophage expansion.
參閱圖1，為目前現有的一種擴張器7，該擴張器7包括一導管71，及一鄰近該導管71前端的氣囊72，進行手術時，將該導管71經由一患者的上消化道穿過一食道的狹窄處後(圖未示)，進行充氣或充水使該氣囊72膨脹 ，即能使該狹窄處被撐開。施行上述之步驟時，假使單憑醫護人員的經驗及手感使用該擴張器7，會無法確定該導管71在該患者的食道內相對於該狹窄處的確切位置，且無法評估該氣囊72膨脹的程度是否恰當，若操作不當，該導管71會搓破該食道造成該食道穿孔或出血，也可能發生該氣囊72膨脹過度導致該食道被撐破的狀況，上述之情況皆會使該患者的縱膈腔感染並造成生命危險，所以使用該擴張器7時需在X光透視下操作，但如此一來，該患者及施行手術的醫護人員都必須長時間暴露於X光照射的環境下，產生危害健康的疑慮。 Referring to Fig. 1, there is a currently existing dilator 7, which includes a catheter 71, and an air bag 72 adjacent to the front end of the catheter 71. When performing surgery, the catheter 71 is passed through a patient's upper digestive tract. After the stenosis of an esophagus (not shown), inflation or water filling causes the balloon 72 to swell , that is, the narrow portion can be opened. When the above steps are performed, if the dilator 7 is used only by the experience and feel of the medical staff, the exact position of the catheter 71 in the esophagus of the patient relative to the stenosis cannot be determined, and the inflation of the balloon 72 cannot be evaluated. Whether the degree is appropriate, if the operation is improper, the catheter 71 may smash the esophagus to cause perforation or bleeding of the esophagus, and the balloon 72 may be over-expanded to cause the esophagus to be broken, and the above situation may cause the patient to be longitudinally The cavity is infected and life-threatening, so the use of the dilator 7 requires X-ray fluoroscopy, but in this case, the patient and the medical staff performing the surgery must be exposed to X-ray exposure for a long time. Health concerns.
參閱圖2與圖3，另一施行食道擴張術的方式是使用一內視鏡8來代替X光照射，該內視鏡8前端設有一攝影鏡頭81，進行手術時，將該內視鏡8及該擴張器7穿入該食道9內，並小心地穿過該食道9的狹窄處91後，控制彎曲該內視鏡8的前端使該攝影鏡頭81對準該狹窄處91，再調整該擴張器7於該食道9內的位置，使該擴張器7的氣囊72對應該狹窄處91的位置，隨後進行充氣使該氣囊72膨脹擴張該狹窄處91，使用上述之方式雖能達到擴張該狹窄處91的目的，且能避免長時間的X光照射，但通常該內視鏡8的直徑是大於該狹窄處91，且該內視鏡8及該擴張器7都必須穿過該狹窄處91才能夠進行擴張，不但操作上困難度高，且會增加患者的不適感與疼痛感。 Referring to FIG. 2 and FIG. 3, another way of performing esophageal dilation is to use an endoscope 8 instead of X-ray illumination. The front end of the endoscope 8 is provided with a photographic lens 81. When performing surgery, the endoscope 8 is used. And the dilator 7 penetrates into the esophagus 9 and carefully passes through the narrow portion 91 of the esophagus 9, and then controls the front end of the endoscope 8 to bend the photographic lens 81 to the narrow portion 91, and then adjusts the The position of the dilator 7 in the esophagus 9 causes the balloon 72 of the dilator 7 to correspond to the position of the stenosis 91, and then inflates the balloon 72 to expand and expand the stenosis 91, which can be expanded using the above-described manner. The purpose of the stenosis 91 is to avoid long-term X-ray irradiation, but generally the diameter of the endoscope 8 is larger than the stenosis 91, and the endoscope 8 and the dilator 7 must pass through the stenosis 91 can only expand, not only the difficulty of operation, but also increase the patient's discomfort and pain.
因此，本發明之目的，即在提供一種較易於操 作且能減輕病患手術時的不適感的內視鏡之膨脹氣囊擴張裝置。 Therefore, the object of the present invention is to provide a relatively easy to operate An inflatable balloon expansion device for an endoscope that can reduce the discomfort during surgery.
於是，本發明內視鏡之膨脹氣囊擴張裝置，適合設置於一內視鏡的導管，該導管具有一前端，及一相反於該前端的後端，該膨脹氣囊擴張裝置包含一氣囊，及一充氣管。 Therefore, the inflation balloon expansion device of the endoscope of the present invention is suitable for a catheter disposed in an endoscope having a front end and a rear end opposite to the front end, the inflation balloon expansion device comprising an air bag, and a Inflatable tube.
該氣囊具可充氣性且設置於該導管的外周面並鄰近該前端，該氣囊具有一環繞該導管的內環壁、分別位於該內環壁的兩相反側的一前側壁及一後側壁，及一充氣口，該後側壁遠離該導管的前端，該充氣口設置於該後側壁且鄰近該導管。 The air bag is inflatable and disposed on the outer circumferential surface of the duct and adjacent to the front end. The air bag has an inner ring wall surrounding the duct, and a front side wall and a rear side wall respectively on opposite sides of the inner ring wall. And an inflating port, the rear side wall being away from the front end of the duct, the inflating port being disposed on the rear side wall and adjacent to the duct.
該充氣管與該氣囊連接，該充氣管的一端插入該充氣口且遠離該前端。 The inflation tube is coupled to the air bag, and one end of the inflation tube is inserted into the inflation port and away from the front end.
本發明之功效在於，藉由該氣囊的充氣口遠離該內視鏡的前端之設置方式，僅需讓該導管穿過一體腔管道內的狹窄處，即可進行該氣囊的充氣膨脹，如此可避免該充氣管與該導管同時穿過該狹窄處，不但能降低操作該內視鏡時的困難度，且能減少患者的不適感。 The effect of the invention is that, by means of the arrangement of the inflation port of the airbag away from the front end of the endoscope, the inflation of the airbag can be performed only by passing the catheter through a narrow portion in the pipe of the integral cavity. Avoiding the inflation tube and the catheter passing through the narrow portion at the same time can not only reduce the difficulty in operating the endoscope, but also reduce the patient's discomfort.

The inflation balloon expansion device 5 includes an air bag 51, an inflation tube 52 connected to the air bag 51, and a check valve 53.
該氣囊51為彈性材質，具可充氣性且設置於該導管2的外周面21並鄰近該前端22，該氣囊51具有一環繞該導管2的內環壁511、一與該內環壁511相間隔設置的外環壁512、一前側壁513、一後側壁514、一充氣口515、一由該內環壁511圍繞界定出且能供該導管2穿設的穿孔516，及一由該內環壁511、該外環壁512、該前側壁513及該後側壁514共同圍繞界定的儲氣室517。 The air bag 51 is made of an elastic material and is inflatable and disposed on the outer peripheral surface 21 of the duct 2 adjacent to the front end 22. The air bag 51 has an inner ring wall 511 surrounding the duct 2 and a inner ring wall 511. An outer ring wall 512, a front side wall 513, a rear side wall 514, an inflation port 515, a perforation 516 defined by the inner ring wall 511 and capable of being passed through the duct 2, and a hole 516 The annular wall 511, the outer annular wall 512, the front side wall 513 and the rear side wall 514 collectively surround the defined gas storage chamber 517.
該前側壁513及該後側壁514分別位於該內環壁511的兩相反側，且該前側壁513鄰近該前端22，該後側壁514遠離該前端22。於本較佳實施例中，該穿孔516的內徑略小於該導管2的外徑。 The front side wall 513 and the rear side wall 514 are respectively located on opposite sides of the inner ring wall 511 , and the front side wall 513 is adjacent to the front end 22 , and the rear side wall 514 is away from the front end 22 . In the preferred embodiment, the inner diameter of the perforation 516 is slightly smaller than the outer diameter of the catheter 2.
該充氣口515呈細圓管狀且設置於該後側壁514並鄰近該導管2，該充氣管52的一端插入該充氣口515且與該儲氣室517相連通，另一端與該逆止閥53密合連接，於本較佳實施例中，該充氣管52的直徑小於該導管2的直徑。 The inflation port 515 is in a thin tubular shape and is disposed on the rear side wall 514 and adjacent to the conduit 2. One end of the inflation tube 52 is inserted into the inflation port 515 and communicates with the gas storage chamber 517, and the other end and the check valve 53 In the preferred embodiment, the diameter of the inflation tube 52 is smaller than the diameter of the catheter 2.
參閱圖4、圖5與圖6，欲進行食道100擴張的手術時，開啟該攝影鏡頭3及該發光元件4，將該導管2經由一患者的上消化道(圖未示)伸入至該患者的食道100並朝該狹窄處101的方向移動，該導管2的前端22會逐漸地撐開該狹窄處101，並能導引該導管2順利地通過該狹窄處101。 Referring to FIG. 4, FIG. 5 and FIG. 6, when the operation of the esophagus 100 is expanded, the photographic lens 3 and the illuminating element 4 are turned on, and the catheter 2 is inserted into the upper digestive tract (not shown) of the patient. The patient's esophagus 100 moves toward the stenosis 101, and the front end 22 of the catheter 2 gradually expands the stenosis 101 and guides the catheter 2 through the stenosis 101 smoothly.
參閱圖4與圖7，該導管2穿過該狹窄處101後，控制彎曲該導管2的前端22，使該攝影鏡頭3對準該 狹窄處101，並將該導管2穿伸至該氣囊51對應該狹窄處101的位置，即可進行該氣囊51的充氣膨脹。將一打氣裝置(圖未示)與該逆止閥53連接進行充氣，氣體會經由該逆止閥53及該充氣管52填入該氣囊51內部，且該逆止閥53能使打入該充氣管52的氣體單向穩定輸送至該氣囊51，該氣囊51隨者打入的氣體變多而膨脹並撐開該狹窄處101，此時，利用該攝影鏡頭3傳輸的影像，即能判斷該氣囊51的膨脹程度是否恰當且能斟酌手術所需的時間，達成使該狹窄處101擴張的目的。 Referring to FIG. 4 and FIG. 7, after the catheter 2 passes through the narrow portion 101, the front end 22 of the catheter 2 is controlled to be bent to align the photographic lens 3 with the photographic lens 3. The balloon 101 is inflated and expanded by penetrating the catheter 2 to the position where the balloon 51 corresponds to the stenosis 101. An air pumping device (not shown) is connected to the check valve 53 for inflation, and the gas is filled into the air bag 51 via the check valve 53 and the air tube 52, and the check valve 53 can be driven into the air bag 51. The gas of the inflation tube 52 is unidirectionally and stably delivered to the airbag 51, and the airbag 51 expands and expands the narrow portion 101 as the gas that is driven by the airbag 51. At this time, the image transmitted by the photographic lens 3 can be judged. Whether the degree of inflation of the airbag 51 is appropriate and the time required for the surgery can be considered, and the purpose of expanding the stenosis 101 is achieved.
在上述之較佳實施例中，該內視鏡1是以食道擴張的應用為例，但該內視鏡1的應用不限於食道，幽門、氣管或其它體腔內之管道皆可使用上述之較佳實施例的技術手段來進行擴張。 In the above preferred embodiment, the endoscope 1 is exemplified by the application of esophageal dilation, but the application of the endoscope 1 is not limited to the esophagus, and the pylorus, trachea or other body cavity can be used. The technical means of the preferred embodiment are for expansion.
綜上所述，利用該氣囊51的充氣口515位於該後側壁514且遠離該內視鏡的前端22之設置方式，僅需讓該導管2穿過該食道100的狹窄處101，即可進行該氣囊51的充氣膨脹，如此可避免同時讓該充氣管52與該導管2穿過該狹窄處101，不但能降低操作該內視鏡時的困難度、避免因操作不當所造成之食道100穿破或出血的情況，且能減少患者的不適感與疼痛感，本發明並可擴及應用於其他消化道，如胃、腸膽、胰臟等管腔狹窄病症之使用，故確實能達成本發明之目的。 In summary, the manner in which the inflation port 515 of the air bag 51 is located on the rear side wall 514 and away from the front end 22 of the endoscope is only required to pass the catheter 2 through the narrow portion 101 of the esophagus 100. The inflation of the airbag 51 is expanded, so that the inflation tube 52 and the catheter 2 can be prevented from passing through the narrow portion 101 at the same time, which not only reduces the difficulty in operating the endoscope, but also avoids the esophagus 100 worn by improper operation. In the case of broken or bleeding, and can reduce the patient's discomfort and pain, the present invention can be extended to other digestive tracts, such as the use of stenosis of the stomach, intestines, and pancreas, so it is possible to achieve this. The purpose of the invention.
惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申 請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto. The simple equivalent changes and modifications made by the patent scope and the contents of the patent specification are still within the scope of the invention.
