技术领域technical field

本发明是关于一种内视镜装置，特别是关于一种可以对人体体腔进行医学检查的工具。The invention relates to an endoscope device, in particular to a tool capable of performing medical inspection on a body cavity of a human body.

背景技术Background technique

一般内视镜是一条特制的管子，主要由摄影装置及光源构成，接上显示器后可将身体内部的构造显示在屏幕上。医生通过观察屏幕上的影像诊断受检者的疾病。身体内部的器官，只要有孔道与身体外相通，就可以利用内视镜进行检查，例如喉内视镜(检查声带、咽喉等)是经由鼻腔置入内视镜；上消化道内视镜(检查食道、胃及十二指肠)是经口腔置入；大肠镜则经由肛门进入等。若无孔道可以借助，也可由手术建立孔道来实现，例如腹腔镜检查时需要在腹部打洞；关节镜需要切开关节周围的皮肤等。Generally, the endoscope is a special tube, which is mainly composed of a camera and a light source. After being connected to a monitor, the internal structure of the body can be displayed on the screen. The doctor diagnoses the subject's disease by observing the images on the screen. Internal organs of the body, as long as there is a channel that communicates with the outside of the body, can be checked with an endoscope. For example, a laryngoscope (to check the vocal cords, throat, etc.) is inserted through the nasal cavity; an upper gastrointestinal endoscope (to check Esophagus, stomach and duodenum) are inserted through the mouth; colonoscopy is inserted through the anus, etc. If there is no hole to use, it can also be achieved by establishing a hole through surgery. For example, a hole needs to be made in the abdomen during laparoscopy; arthroscopy needs to cut the skin around the joint, etc.

内视镜检查是一种具有侵袭性的检查方式，在内视镜进入人体的过程中常会引起受检者的不适，严重者甚至会导致休克；同时体内的器官十分柔软、脆弱，稍微不慎就可能被内视镜管子碰伤。再者，由于现有的内视镜造价较高，故每次使用后都需要进行清洗、消毒，供下一位受检者使用，经常会有因消毒不彻底，造成患者交叉感染的病例发生。因此如何在使用内视镜时不引起痛苦、更易操作、无交叉感染，一直是业界亟待克服的瓶颈。Endoscopic examination is an invasive examination method. When the endoscope enters the human body, it often causes discomfort to the subject, and in severe cases, it may even lead to shock. At the same time, the organs in the body are very soft and fragile. It may be bruised by the endoscope tube. Furthermore, due to the high cost of the existing endoscopes, they need to be cleaned and disinfected after each use for the next examinee to use. There are often cases of cross-infection of patients due to incomplete disinfection. . Therefore, how to use the endoscope without causing pain, making it easier to operate, and avoiding cross-infection has always been a bottleneck that needs to be overcome in the industry.

近年来由于影像技术及光学纤维仪器的突破，使得内视镜不论是在体积上或是柔软度上都有显著的进步，甚至已发展出可操控弯曲角度的内视镜，如美国专利第6,432,043号。该专利发明了一种用于插入气管的内视镜，该内视镜除了插入部分、把手操作部分外，进一步包括操控弯曲的机制以及使插入部分弯曲的机制。该弯曲机制包括一长形弹性构件，此弹性构件的一端是位于插入部分的末端，另一端则固定在操控弯曲的机制中的L形把手的一端。弹性构件是在内视镜管内随着插入部分延伸，L形把手则是短边端在管内，长边端在管外。医疗人员借由握着管外部分的把手，以推-拉的方式操控内视镜插入部分的弯曲角度。不过以此方式控制的弯曲角度仍有其限制，它无法窥视被检查器官内部的全貌。In recent years, due to breakthroughs in imaging technology and optical fiber instruments, endoscopes have made significant progress in both volume and flexibility, and even endoscopes that can control the bending angle have been developed, such as US Patent No. 6,432,043 Number. This patent discloses an endoscope for inserting into the trachea, the endoscope further includes a mechanism for controlling bending and a mechanism for bending the insertion part in addition to the insertion part and the handle operation part. The bending mechanism includes an elongated elastic member, one end of which is located at the end of the insertion portion, and the other end is fixed to one end of an L-shaped handle in the bending mechanism. The elastic member extends along with the insertion part in the endoscope tube, and the L-shaped handle is in the tube at the short side end and outside the tube at the long side end. The medical staff controls the bending angle of the insertion part of the endoscope in a push-pull manner by holding the handle of the outer part of the tube. However, the bending angle controlled in this way still has its limitations, and it cannot peek into the whole picture of the interior of the organ being inspected.

此外，在肠胃道内视镜检查方面，当内视镜插入体内后，需对该内视镜施力，使内视镜的插入部分沿着消化管道前进，当内视镜前端遇到消化道的转弯处时，常会对消化道的内壁造成伤害，例如易造成穿孔。为了解决此类问题，发展出无线内视镜，例如美国专利第6,402,686、6,402,687以及6,428,469号。其中美国专利第6,428,469号发明了一种胶囊内视镜，它包括影像单位、连接至影像单位的控制单位以及连接至控制单位的电源。当用胶囊内视镜进行检查时，受检者必需先吞服该内视镜，并长时间随身穿戴厚重的感应器，以接收由进入体内并沿消化道前进的胶囊内视镜传回的影像，同时储存至硬盘中，待检查结束后，即可使用计算机观看所拍摄的影像，以进行诊断。由于该胶囊内视镜的电源是依赖内置的电池，所以当电池的电力耗尽后(约8小时)就无法继续拍摄消化道内的情形。又，该胶囊内视镜是沿人体的消化道持续前进，故无法来回重复观看同一部位，且也有可能发生胶囊卡在肠道内等问题。同时，长时间穿戴厚重的感应器也会造成受检者的负担与不适。此外，倘若受检者途中因故脱下感应器，则会中断影像的储存，导致影像无法连贯，进而影响检查结果与病情诊断。再者，这种胶囊内视镜的造价较高，再加上上述种种使用上的问题，使得该产品迄今仍难以遍及。In addition, in terms of endoscopic examination of the gastrointestinal tract, when the endoscope is inserted into the body, it is necessary to apply force to the endoscope so that the insertion part of the endoscope advances along the digestive tract. When turning, it often causes damage to the inner wall of the digestive tract, such as perforation. In order to solve such problems, wireless endoscopes have been developed, such as US Pat. Nos. 6,402,686, 6,402,687 and 6,428,469. Among them, US Patent No. 6,428,469 has invented a capsule endoscope, which includes an imaging unit, a control unit connected to the imaging unit, and a power supply connected to the control unit. When checking with a capsule endoscope, the examinee must first swallow the endoscope and wear a heavy sensor for a long time to receive the information sent back by the capsule endoscope that enters the body and advances along the digestive tract. The images are stored in the hard disk at the same time. After the inspection is completed, the captured images can be viewed on the computer for diagnosis. Since the power supply of the capsule endoscope relies on the built-in battery, so when the power of the battery is exhausted (about 8 hours), the situation in the digestive tract cannot be continued. In addition, the capsule endoscope continues to advance along the digestive tract of the human body, so it is impossible to repeatedly view the same part back and forth, and problems such as the capsule getting stuck in the intestinal tract may also occur. At the same time, wearing a heavy sensor for a long time will also cause burden and discomfort to the examinee. In addition, if the subject takes off the sensor for some reason on the way, the storage of the image will be interrupted, causing the image to be incoherent, which will affect the test result and disease diagnosis. Furthermore, the high cost of this capsule endoscope, coupled with the above-mentioned various problems in use, makes this product still difficult to popularize so far.

实施例2Example 2

图4A至图4C是本发明内视镜装置的实施例2，其中是使用引导套管122控制头部110弯曲的角度。首先将引导套管122自形状记忆性中空导管120后端套入，再向前推至头部110与形状记忆性中空导管120相连接处，使弯曲的形状记忆性中空导管120伸直，此时可借由操控引导套管122向前或往后移动的程度，控制头部110旋转的角度。再者，图4A至图4C也是具有各种不同弯曲形状的本发明内视镜装置，图4A为U形弯曲的内视镜装置；图4B为S形弯曲的内视镜装置；以及图4C为O形弯曲的内视镜装置。4A to 4C are Embodiment 2 of the endoscope device of the present invention, in which a guidingsleeve 122 is used to control the bending angle of thehead 110 . First, insert theguide sleeve 122 from the rear end of the shape-memoryhollow catheter 120, and then push it forward to the connection between thehead 110 and the shape-memoryhollow catheter 120, so that the curved shape-memoryhollow catheter 120 is straightened. During this time, the rotation angle of thehead 110 can be controlled by manipulating the degree of forward or backward movement of theguide sleeve 122 . Furthermore, Fig. 4A to Fig. 4C are also endoscope devices of the present invention with various curved shapes, Fig. 4A is a U-shaped curved endoscope device; Fig. 4B is an S-shaped curved endoscope device; and Fig. 4C It is an O-shaped curved endoscope device.

引导线121及引导套管122的材质并无特别限制，只要是具有组织兼容性，可用于体内手术的材质皆可。考虑到卫生性及为避免可能的感染，最好采用适于抛弃式的材质。相对于形状记忆性中空导管120，引导线121与引导套管122具有较大的坚韧性，可将原本为弯曲状的形状记忆性中空导管120伸直。此外，为使引导线121可滑顺地在形状记忆性中空导管120中前后移动，在引导线的外层涂覆一层自润性物质，例如特氟龙。The materials of the guide wire 121 and theguide cannula 122 are not particularly limited, as long as they are compatible with tissues, they can be used for in vivo surgery. Considering hygiene and avoiding possible infection, it is best to use materials suitable for disposables. Compared with the shape-memoryhollow catheter 120 , the guide wire 121 and theguide sheath 122 have greater toughness, and can straighten the originally curved shape-memoryhollow catheter 120 . In addition, in order to make the guide wire 121 move back and forth smoothly in the shape-memoryhollow catheter 120 , a layer of self-lubricating substance, such as Teflon, is coated on the outer layer of the guide wire.

图5A至图5D所示，是以检查人体的胃部为例，说明本发明内视镜装置10的使用方法。在进行内视镜检查前先将引导套管122自形状记忆性中空导管120后端套入，向前推至头部110与形状记忆性中空导管120邻接处，使弯曲的形状记忆性中空导管120伸直。自人体口腔中、经由食道将本发明内视镜装置10插入胃中，如图5A。当医生要观察胃内的其它区域时，可在口腔外将引导套管向上拉，使部分形状记忆性中空导管120恢复到其原本的弯曲状态，也就是借由形状记忆性中空导管120恢复弯曲程度，调整本发明内视镜装置10中摄影系统1133可拍摄的角度，如图5B至图D，图中空心箭头所指的方向表示引导套管122移动的方向，空心箭头的大小表示引导套管122的移动程度。当医生要观察胃内右半部时，只需在口腔外稍微旋转形状记忆性中空导管120即可。因此，本发明的内视镜装置10可借由操纵引导套管122向前推或往后拉，控制形状记忆性中空导管120恢复弯曲的程度以及旋转形状记忆性中空导管120，使本发明的内视镜装置10可全方位地观察人体休腔内部。As shown in FIG. 5A to FIG. 5D , the method of using theendoscope device 10 of the present invention is described by taking the examination of the stomach of a human body as an example. Before endoscopic examination, theguide sleeve 122 is inserted from the rear end of the shape-memoryhollow catheter 120, and pushed forward to the adjoining place between thehead 110 and the shape-memoryhollow catheter 120, so that the curved shape-memoryhollow catheter 120 straight. Insert theendoscopic device 10 of the present invention into the stomach from the oral cavity of the human body through the esophagus, as shown in FIG. 5A . When the doctor wants to observe other areas in the stomach, the guide sleeve can be pulled up outside the oral cavity to restore part of the shape-memoryhollow catheter 120 to its original bending state, that is, the shape-memoryhollow catheter 120 restores the bending Adjust the angle that can be photographed by thecamera system 1133 in theendoscope device 10 of the present invention, as shown in Figure 5B to Figure D, the direction pointed by the hollow arrow in the figure indicates the direction in which theguide sleeve 122 moves, and the size of the hollow arrow indicates the direction of the guide sleeve The degree of movement of thetube 122.
