内窥镜孔道缝合夹Endoscopic Orifice Suture Clip

技术领域technical field

本实用新型涉及医疗技术领域，具体而言，涉及一种内窥镜孔道缝合夹。The utility model relates to the field of medical technology, in particular to an endoscope hole suture clip.

背景技术Background technique

本实用新型对于背景技术的描述属于与本实用新型相关的相关技术，仅仅是用于说明和便于理解本实用新型的实用新型内容，不应理解为申请人明确认为或推定申请人认为是本实用新型在首次提出申请的申请日的现有技术。The description of the background technology of the present utility model belongs to the related technology related to the present utility model, and is only used to illustrate and facilitate the understanding of the utility model content of the present utility model. The new type of prior art on the filing date of the first application.

随着内镜微创技术发展，以前需要外科开腹或者腹腔镜处理的一些消化道疾病，比如消化道早期肿瘤，均能在消化内镜微创下治疗。在内镜微创手术过程中，消化道粘膜缺损缝合，包括消化道出血及穿孔，是最常见的问题。目前，主要使用的缺损缝合方法有，内镜夹，尼龙绳联合内镜夹荷包缝合及内镜缝合装置(OTSC)。内镜夹使用简单且费用较便宜，但是，对于较大的缺损或者困难部位的缺损难以发挥修补作用。OTSC由国外专家实用新型，费用昂贵，操作较复杂，需要前期的培训才能使用。因此，一种“内窥镜孔道缝合夹”被设计，该设计旨在能简单快捷及有效地对大的消化道缺损及困难操作部位的缺损进行夹持并缝合。With the development of minimally invasive endoscopic techniques, some gastrointestinal diseases that previously required surgical laparotomy or laparoscopy, such as early gastrointestinal tumors, can be treated with minimally invasive digestive endoscopy. During endoscopic minimally invasive surgery, suturing of gastrointestinal mucosal defects, including gastrointestinal bleeding and perforation, is the most common problem. At present, the main defect suturing methods are endoscopic clip, nylon rope combined with endoscopic clip purse-string suture and endoscopic suturing device (OTSC). Endoscope clips are easy to use and inexpensive, but they are difficult to repair for larger defects or defects in difficult parts. OTSC is a utility model developed by foreign experts, which is expensive and complicated to operate, and requires pre-training before it can be used. Therefore, an "endoscopic tunnel suture clip" is designed, which is designed to clamp and suture large alimentary tract defects and defects in difficult-to-operate sites simply, quickly and effectively.

第一滑槽111沿外壳110的轴向设置；外壳110上设置有贯穿外壳110 的第一通槽117。夹持芯100与外壳110固定连接。两个夹持部120通过转轴130安装在外壳110上，并可相对于外壳110转动，两个夹持部120位于第一通槽117内，第一通槽117上对称的两个槽壁上分别设置有第一滑槽111，第一滑槽111为贯穿外壳110的通孔，夹持部120上设置有第二滑槽121，第二滑槽121包括导向槽1211和限位槽1212。两个控制组件200 分别与两个夹持部120连接，两个控制组件200分别独立控制两个夹持部 120相对于夹持芯100打开或者闭合，以夹持目标物。The first slidinggroove 111 is disposed along the axial direction of thecasing 110 ; thecasing 110 is provided with a first throughgroove 117 penetrating thecasing 110 . The clampingcore 100 is fixedly connected to thehousing 110 . The two clampingparts 120 are mounted on thecasing 110 through therotating shaft 130 and can be rotated relative to thecasing 110 . The two clampingparts 120 are located in the first throughgroove 117 . First slidinggrooves 111 are respectively provided. The first slidinggrooves 111 are through holes passing through thehousing 110 . The clampingportion 120 is provided with a second slidinggroove 121 . The second slidinggrooves 121 include aguide groove 1211 and alimit groove 1212 . The twocontrol assemblies 200 are respectively connected with the two clampingparts 120, and the twocontrol assemblies 200 independently control the two clampingparts 120 to open or close relative to theclamping core 100 to clamp the target object.

如图2和图3所示，控制组件200包括：滑块211和控制件212。滑块 211设置在第二滑槽121内，并可在第二滑槽121内滑动，夹持部120与夹持芯100闭合后，滑块211能够卡入限位槽1212内。控制件212的一端与滑块211连接，另一端伸出外壳110，控制件212的一部分位于第一滑槽 111内，并可在第一滑槽111内滑动。As shown in FIG. 2 and FIG. 3 , thecontrol assembly 200 includes: aslider 211 and acontrol member 212 .

After the clampingportion 120 and theclamping core 100 are closed, the slidingblock 211 can be snapped into the limitinggroove 1212. One end of thecontrol member 212 is connected to theslider 211, and the other end extends out of thehousing 110. A part of thecontrol member 212 is located in thefirst chute 111 and can slide in thefirst chute 111.

在该实施例中，在夹持缺损创面时，向前推一控制件212，控制件212 在第二滑槽121内滑动，从而使夹持部120绕转轴130转动，夹持部120 与夹持芯100之间的距离变大，然后将缺损创面的一侧放置在夹持部120 与夹持芯100之间，向后拉控制件212，控制件212在第二滑槽121内滑动，从而使夹持部120绕转轴130转动，夹持部120与夹持芯100之间的距离变小，以夹持缺损创面的一侧。同理，然后打开另一个夹持部120，以夹持缺损创面的另一侧，即两个夹持部120可以分别单独夹持缺损创面的一部分，最终实现夹持整个缺损创面的功能，从而有效地解决了常规止血夹只可单侧夹持从而难以处理大尺寸的或者困难操作部位的缺损创面的难题。In this embodiment, when clamping the defect wound, acontrol member 212 is pushed forward, and thecontrol member 212 slides in thesecond chute 121, so that the clampingpart 120 rotates around therotating shaft 130, and the clampingpart 120 and the clamp The distance between the holdingcores 100 becomes larger, and then one side of the defect wound is placed between the clampingpart 120 and theclamping core 100, thecontrol member 212 is pulled back, and thecontrol member 212 slides in thesecond chute 121, Therefore, the clampingportion 120 is rotated around therotating shaft 130, and the distance between the clampingportion 120 and theclamping core 100 is reduced, so as to clamp one side of the defect wound. In the same way, the other clampingpart 120 is then opened to clamp the other side of the defect wound surface, that is, the two clampingparts 120 can respectively clamp a part of the defect wound surface, and finally realize the function of clamping the entire defect wound surface. It effectively solves the problem that conventional hemostatic clips can only be clamped on one side, which makes it difficult to treat large-sized or difficult-to-operate defect wounds.

另外，控制件212具有一定刚性，从而使滑块211与控制件212的行程的行程相同，操作者可通过控制件212和滑块211的配合控制夹持部120 在较小的范围内开闭，进而实现比较精密的缺损创面。可选地，控制件212 采用塑料制成，或者，控制件212采用金属制成。In addition, thecontrol member 212 has a certain rigidity, so that the stroke of theslider 211 and the stroke of thecontrol member 212 are the same, and the operator can control the clampingpart 120 to open and close in a relatively small range through the cooperation of thecontrol member 212 and theslider 211 , and then achieve a more precise defect wound.
