技术领域Technical Field
本发明涉及医疗器械技术领域，具体涉及一种吻合口保护装置。The present invention relates to the technical field of medical devices, and in particular to an anastomotic stoma protection device.
背景技术Background technique
在肠道进行切割缝合手术后，为了避免排泄物对吻合口施加张力、或为了避免排泄物污染吻合口而造成吻合口感染，一般都需要对吻合口进行保护。After intestinal cutting and suturing surgery, the anastomosis generally needs to be protected to prevent excrement from exerting tension on the anastomosis or to prevent excrement from contaminating the anastomosis and causing anastomotic infection.
现有的吻合口保护方式一般为：在肠道内部设置管状套管，套管覆盖肠道内表面对应于吻合口的位置，通过套管将排泄物引流至人体外，不仅可以有效保护吻合口，还可以在吻合口生理组织生长好后，无需进行二次手术，直接取出套管即可。为了将套管更好地固定在所需要的位置，需要在套管的外部设置具有固定直径且配置为定位环绕肠道的固定带。然而，此固定带不可避免地会对肠道形成一定压力，会对肠道的正常蠕动形成阻碍，并且可能会因为固定带的持续压力造成吻合口附近供血不良等问题。The existing anastomotic protection method is generally: a tubular sleeve is set inside the intestine, the sleeve covers the inner surface of the intestine corresponding to the position of the anastomosis, and the excrement is drained out of the human body through the sleeve. It can not only effectively protect the anastomosis, but also after the physiological tissue of the anastomosis grows well, there is no need for a secondary operation, and the sleeve can be directly removed. In order to better fix the sleeve in the required position, it is necessary to set a fixing belt with a fixed diameter and configured to position and surround the intestine on the outside of the sleeve. However, this fixing belt will inevitably exert a certain pressure on the intestine, which will hinder the normal peristalsis of the intestine, and may cause problems such as poor blood supply near the anastomosis due to the continuous pressure of the fixing belt.

具体实施方式Detailed ways
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本发明将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构，因而将省略对它们的重复描述。Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.
本发明提供了一种吻合口保护装置，所述装置包括保护套、第一固定组件、第二固定组件和供电组件。所述保护套位于管状组织内部与吻合口相对应的位置，保护套对吻合口的内表面起到保护作用，在引导管状组织内容物通过的过程中不会污染吻合口。所述第一固定组件设置于所述管状组织的外壁，所述第一固定组件包括电磁发生部件，所述电磁发生部件在输入供电电流时可以产生磁性。所述供电组件与所述电磁发生部件电连接，用于对所述电磁发生部件供电。所述第二固定组件设置于所述保护套的内表面，所述第二固定组件本身具有磁性或者可被磁性吸引，与所述电磁发生部件通过磁性吸附而相对固定，因此通过第一固定组件和第二固定组件之间的磁性吸附，将保护套固定在需要的位置。The present invention provides an anastomotic stoma protection device, the device comprising a protective sleeve, a first fixing component, a second fixing component and a power supply component. The protective sleeve is located at a position corresponding to the anastomotic stoma inside the tubular tissue, and the protective sleeve protects the inner surface of the anastomotic stoma, and will not contaminate the anastomotic stoma during the process of guiding the contents of the tubular tissue to pass through. The first fixing component is arranged on the outer wall of the tubular tissue, and the first fixing component comprises an electromagnetic generating component, and the electromagnetic generating component can generate magnetism when a power supply current is input. The power supply component is electrically connected to the electromagnetic generating component and is used to supply power to the electromagnetic generating component. The second fixing component is arranged on the inner surface of the protective sleeve, and the second fixing component itself has magnetism or can be attracted by magnetism, and is relatively fixed to the electromagnetic generating component through magnetic adsorption, so that the protective sleeve is fixed at a desired position through magnetic adsorption between the first fixing component and the second fixing component.
由于该吻合口保护装置中只有第一固定组件和第二固定组件之间的磁性吸附位置是相对固定的，不会阻碍管状组织的正常蠕动，并且给管状组织提供周向伸缩的空间，保证吻合口附近正常的供血。第一固定组件包括可以通电而具有磁性的电磁发生部件，可以通过控制供电的通断来灵活控制电磁发生部件中的磁性有无，并且可以通过控制供电电流的大小和电磁发生部件的绕组匝数来灵活控制电磁发生部件中的磁性大小。Since only the magnetic adsorption position between the first fixing component and the second fixing component in the anastomotic stoma protection device is relatively fixed, it will not hinder the normal peristalsis of the tubular tissue, and provide the tubular tissue with circumferential expansion and contraction space, thereby ensuring the normal blood supply near the anastomotic stoma. The first fixing component includes an electromagnetic generating component that can be energized and has magnetism, and the presence or absence of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the on and off of the power supply, and the magnitude of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the magnitude of the power supply current and the number of turns of the winding of the electromagnetic generating component.
下面结合附图详细介绍本发明各个具体实施例的吻合口保护装置的结构，可以理解的是，各个具体实施例不作为本发明的保护范围的限制。在各个实施例中，以肠道组织为例进行说明。可理解的是，在其他实施方式中，所述管状组织不限于肠道组织，也可以为人体内的其他管状组织，例如消化道中其他位置的管状组织等，均属于本发明的保护范围之内。The structure of the anastomotic stoma protection device of each specific embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It can be understood that each specific embodiment is not intended to limit the protection scope of the present invention. In each embodiment, intestinal tissue is used as an example for illustration. It can be understood that in other embodiments, the tubular tissue is not limited to intestinal tissue, but can also be other tubular tissues in the human body, such as tubular tissues at other locations in the digestive tract, etc., all of which fall within the protection scope of the present invention.
如图1～8所示，为本发明第一实施例的吻合口保护装置应用于肠道组织9的结构示意图。如图1～4所示，所述吻合口保护装置包括：保护套1，位于肠道组织9内部与吻合口相对应的位置，对吻合口的内表面起到保护作用，在引导肠道内容物通过的过程中不会污染吻合口；第一固定组件，设置于所述肠道组织9的外壁，所述第一固定组件包括电磁发生部件；供电组件，与所述电磁发生部件电连接，用于对所述电磁发生部件供电；以及第二固定组件，设置于所述保护套1的内表面，所述第二固定组件与所述第一固定组件的电磁发生部件通过磁性吸附而相对固定。As shown in Figures 1 to 8, it is a schematic diagram of the structure of the anastomotic stoma protection device of the first embodiment of the present invention applied to the intestinal tissue 9. As shown in Figures 1 to 4, the anastomotic stoma protection device includes: a protective sleeve 1, which is located at a position corresponding to the anastomotic stoma inside the intestinal tissue 9, and protects the inner surface of the anastomotic stoma, and will not contaminate the anastomotic stoma during the process of guiding the intestinal contents to pass; a first fixing component, which is arranged on the outer wall of the intestinal tissue 9, and the first fixing component includes an electromagnetic generating component; a power supply component, which is electrically connected to the electromagnetic generating component and is used to supply power to the electromagnetic generating component; and a second fixing component, which is arranged on the inner surface of the protective sleeve 1, and the second fixing component and the electromagnetic generating component of the first fixing component are relatively fixed by magnetic adsorption.
由于该装置中只有第一固定组件和第二固定组件之间的磁性吸附位置是相对固定的，不会阻碍管状组织的正常蠕动，并且给管状组织提供周向伸缩的空间，保证吻合口附近正常的供血。第一固定组件中的电磁发生部件可在通过供电组件供电时产生磁性。因此可以通过控制供电的通断来灵活控制电磁发生部件中的磁性有无，并且可以通过控制供电电流的大小来灵活控制电磁发生部件中的磁性大小。Since only the magnetic adsorption position between the first fixing component and the second fixing component in the device is relatively fixed, it will not hinder the normal peristalsis of the tubular tissue, and provide the tubular tissue with space for circumferential expansion and contraction, thereby ensuring normal blood supply near the anastomosis. The electromagnetic generating component in the first fixing component can generate magnetism when powered by the power supply component. Therefore, the presence or absence of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the on and off of the power supply, and the magnitude of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the magnitude of the power supply current.
在该实施例中，所述电磁发生部件为电磁铁2。电磁铁是通电产生电磁的一种结构，在铁芯的外部缠绕与其功率相匹配的导电绕组，在向导电绕组中通电时，这种通有电流的绕组像磁铁一样具有磁性。因此，在该实施例中，也可以通过控制所述电磁铁2中的线圈匝数来调整电磁铁2中通入电流后产生的磁性大小。在其他可替代的实施方式中，所述电磁发生部件也可以采用其他结构，例如电磁线圈等，均属于本发明的保护范围之内。In this embodiment, the electromagnetic generating component is an electromagnet 2. An electromagnet is a structure that generates electromagnetism when electricity is supplied. A conductive winding matching its power is wound on the outside of an iron core. When electricity is supplied to the conductive winding, the winding with current supplied has magnetism like a magnet. Therefore, in this embodiment, the magnitude of magnetism generated after current is supplied to the electromagnet 2 can also be adjusted by controlling the number of turns of the coil in the electromagnet 2. In other alternative embodiments, the electromagnetic generating component can also adopt other structures, such as an electromagnetic coil, etc., all of which fall within the protection scope of the present invention.
如图1～4所示，在该实施例中，所述第一固定组件包括间隔设置的多个电磁铁2，所述多个电磁铁2沿所述肠道组织9的周向依次排布，以对所述保护套1形成一个均匀、稳定的固定。所述第二固定组件包括与所述电磁铁2一一对应的内部固定块3。所述内部固定块3可以采用自身不带磁性但可以被磁铁吸引的材料，例如铁、镍、钴等亲磁的金属及其合金等。或者，所述内部固定块3可以采用自身带有磁性的磁性材料，如磁铁等。在该实施例中，多个所述电磁铁2之间设有间隔，多个所述内部固定块3 之间设有间隔。电磁铁2和内部固定块3的数量也可以根据需要选择设置，并且电磁铁2和内部固定块3之间可以形成一一对应的关系，一对多的关系，或者多对一的关系等等，均属于本发明的保护范围之内。在其他可替代的实施方式中，电磁铁2也可以设置为1个和/或内部固定块3也可以设置为1个。As shown in Figures 1 to 4, in this embodiment, the first fixing component includes a plurality of electromagnets 2 arranged at intervals, and the plurality of electromagnets 2 are arranged in sequence along the circumference of the intestinal tissue 9 to form a uniform and stable fixation for the protective sleeve 1. The second fixing component includes an internal fixing block 3 corresponding to the electromagnet 2. The internal fixing block 3 can be made of a material that is not magnetic but can be attracted by a magnet, such as iron, nickel, cobalt and other magnetophilic metals and their alloys. Alternatively, the internal fixing block 3 can be made of a magnetic material that is magnetic, such as a magnet. In this embodiment, a plurality of the electromagnets 2 are provided with intervals, and a plurality of the internal fixing blocks 3 are provided with intervals. The number of the electromagnets 2 and the internal fixing blocks 3 can also be selected and set as needed, and a one-to-one correspondence, a one-to-many relationship, or a many-to-one relationship can be formed between the electromagnets 2 and the internal fixing blocks 3, all of which belong to the protection scope of the present invention. In other alternative embodiments, the electromagnet 2 can also be set to 1 and/or the internal fixing block 3 can also be set to 1.
如图2所示，所述保护套1为管状的保护套管，可以对吻合口形成周向的保护。所述保护套1可以为一个壁厚很薄的具有柔性的薄膜套管，例如橡胶薄膜套管、硅胶薄膜套管等，但本发明不限于此。在其他可替代的实施方式中，所述保护套1也可以采用其他形状，全部或部分覆盖所述吻合口的内壁，均属于本发明的保护范围之内。As shown in FIG. 2 , the protective sleeve 1 is a tubular protective sleeve that can provide circumferential protection for the anastomosis. The protective sleeve 1 can be a thin and flexible film sleeve, such as a rubber film sleeve, a silicone film sleeve, etc., but the present invention is not limited thereto. In other alternative embodiments, the protective sleeve 1 can also be in other shapes, covering the inner wall of the anastomosis in whole or in part, all of which are within the protection scope of the present invention.
所述固定组件优选设置于所述吻合口的上游一侧，用来固定保护套1，使得保护套1不至于向吻合口的下游一侧运动而失去对吻合口的保护。在本发明中，吻合口的上游指的是以肠道内容物沿肠道移动的方向为参照，肠道内容物沿肠道从吻合口的上游一侧向吻合口的下游一侧移动。在该吻合口保护装置应用于肠道低位时，保护套1引导排泄物沿肠道排出，从吻合口上游一侧移动至吻合口下游一侧。The fixing assembly is preferably disposed on the upstream side of the anastomosis to fix the protective sleeve 1 so that the protective sleeve 1 does not move to the downstream side of the anastomosis and lose protection of the anastomosis. In the present invention, the upstream of the anastomosis refers to the direction in which the intestinal contents move along the intestine, and the intestinal contents move along the intestine from the upstream side of the anastomosis to the downstream side of the anastomosis. When the anastomotic stoma protection device is applied to the lower part of the intestine, the protective sleeve 1 guides the excrement to be discharged along the intestine, moving from the upstream side of the anastomosis to the downstream side of the anastomosis.
如图2和图3所示，所述保护套1位于所述吻合口的上游的一端设置有支撑部11，所述支撑部11在所述保护套1的径向方向可伸缩。所述支撑部11在径向方向收缩时，所述保护套1可以整体放入肠道组织9内部或从肠道组织9内部取出，在所述保护套1放置到位之后，所述支撑部11 在径向方向扩张，以形成对保护套1的支撑，保持保护套1的位置。支撑部11可以采用可充气放气的环形气囊，在充气时处于径向扩张状态，在放气时处于径向收缩状态。所述支撑部11也可以采用其他的具有径向可伸缩的弹簧或径向可运动的滑块结构，能够实现支撑部11的外径增大或缩小即可。所述第一固定组件和第二固定组件设置于所述吻合口与所述支撑部11之间，通过与支撑部11的配合可以更好地将保护套1保持在吻合口位置。As shown in Figures 2 and 3, a support portion 11 is provided at one end of the protective sleeve 1 located upstream of the anastomosis, and the support portion 11 is retractable in the radial direction of the protective sleeve 1. When the support portion 11 contracts in the radial direction, the protective sleeve 1 can be placed in the intestinal tissue 9 as a whole or taken out from the intestinal tissue 9. After the protective sleeve 1 is placed in place, the support portion 11 expands in the radial direction to form a support for the protective sleeve 1 and maintain the position of the protective sleeve 1. The support portion 11 can adopt an inflatable and deflated annular airbag, which is in a radial expansion state when inflated and in a radial contraction state when deflated. The support portion 11 can also adopt other radially retractable springs or radially movable slider structures, which can increase or decrease the outer diameter of the support portion 11. The first fixing component and the second fixing component are arranged between the anastomosis and the support portion 11, and the protective sleeve 1 can be better maintained at the anastomotic position by cooperating with the support portion 11.
如图1所示，在该实施例中，所述供电组件包括供电线束6，所述供电线束6环绕所述肠道组织9的外壁，且分别与各个所述电磁铁2电连接。所述供电线束6可以与外部电源7电连接，外部电源7通过供电线束 6向电磁铁2的导电绕组供电，使得电磁铁2产生磁性。电磁铁2可以使用在通电时具有磁性，在断电时快速消磁的结构。在需要将电磁铁2固定于肠道组织9的外壁时，通过外部电源7在供电线束6中通电，从而使得电磁铁2与内部固定块3磁性吸附。在使用过程中，供电线束6持续为电磁铁2供电。内部固定块3为本身具有磁性的磁性块时，电磁铁2与内部固定块3的磁性相反。需要将电磁铁2从肠道组织9的外壁移除时，可以切断外部电源7对供电线束6的供电，使得电磁铁2失去磁性。通过控制供电线束6中供电电流的大小，也可以控制电磁铁2的磁性强度大小。在其他可替代的实施方式中，所述电磁铁2也可以采用在断电后缓慢消磁的结构，即在供电具有磁性之后，再断电时，能够保持一段时间磁性。As shown in FIG1 , in this embodiment, the power supply assembly includes a power supply harness 6, which surrounds the outer wall of the intestinal tissue 9 and is electrically connected to each of the electromagnets 2. The power supply harness 6 can be electrically connected to an external power source 7, and the external power source 7 supplies power to the conductive winding of the electromagnet 2 through the power supply harness 6, so that the electromagnet 2 generates magnetism. The electromagnet 2 can use a structure that has magnetism when powered on and quickly demagnetizes when powered off. When the electromagnet 2 needs to be fixed to the outer wall of the intestinal tissue 9, the power supply harness 6 is powered by the external power source 7, so that the electromagnet 2 and the internal fixing block 3 are magnetically adsorbed. During use, the power supply harness 6 continuously supplies power to the electromagnet 2. When the internal fixing block 3 is a magnetic block that is itself magnetic, the magnetism of the electromagnet 2 is opposite to that of the internal fixing block 3. When the electromagnet 2 needs to be removed from the outer wall of the intestinal tissue 9, the power supply of the external power source 7 to the power supply harness 6 can be cut off, so that the electromagnet 2 loses its magnetism. By controlling the magnitude of the power supply current in the power supply harness 6, the magnitude of the magnetic strength of the electromagnet 2 can also be controlled. In other alternative embodiments, the electromagnet 2 may also be structured to slowly demagnetize after power is cut off, that is, after being magnetic when powered on, it can maintain its magnetism for a period of time when power is cut off.
如图4所示，所述供电线束6包括多个线束承载部61和多个线束连接部62，所述线束承载部61为环状的中空结构，环绕于所述电磁铁2的外部，所述线束连接部62连接于两个相邻的所述线束承载部61之间，所述线束承载部61和所述线束连接部62组合形成环绕所述肠道组织9的外壁的环状结构。如图4所示，所述电磁铁2的侧面设置有沿周向的第一安装槽22，所述供电线束6的线束承载部61嵌设于所述第一安装槽22 中，从而保证所述电磁铁2与所述供电线束6之间稳定的连接。在另一可替代的实施方式中，也可以是所述供电线束6的线束承载部61的内侧面设置有沿周向的第一安装槽，所述电磁铁2嵌设于所述第一安装槽中。为了更方便地将电磁铁2安装于供电线束6和从供电线束6中移除，所述电磁铁2与所述安装孔的内壁相贴的各个侧壁具有圆角21结构。As shown in FIG4 , the power supply harness 6 includes a plurality of harness bearing parts 61 and a plurality of harness connecting parts 62. The harness bearing part 61 is an annular hollow structure surrounding the outside of the electromagnet 2. The harness connecting part 62 is connected between two adjacent harness bearing parts 61. The harness bearing part 61 and the harness connecting part 62 are combined to form an annular structure surrounding the outer wall of the intestinal tissue 9. As shown in FIG4 , a first mounting groove 22 along the circumferential direction is provided on the side of the electromagnet 2. The harness bearing part 61 of the power supply harness 6 is embedded in the first mounting groove 22, thereby ensuring a stable connection between the electromagnet 2 and the power supply harness 6. In another alternative embodiment, the inner side surface of the harness bearing part 61 of the power supply harness 6 may also be provided with a first mounting groove along the circumferential direction, and the electromagnet 2 is embedded in the first mounting groove. In order to more conveniently install the electromagnet 2 on and remove it from the power supply harness 6 , each side wall of the electromagnet 2 that is in contact with the inner wall of the installation hole has a rounded corner 21 structure.
在该实施例中，所述供电线束6为弹性线束6，并且至少所述线束连接部62的位置处是具有弹性的，从而可以随肠道的蠕动发生弹性形变，而不会给肠道施加限制压力，给肠道提供了可伸缩的运动空间。在所述线束承载部61和所述线束连接部62都是弹性的时候，所述线束连接部62 的弹性优选大于所述线束承载部61的弹性，线束承载部61可以与电磁铁2形成更稳定的连接，线束连接部62的弹性变形力更好，可以提供更好的周向伸缩空间。In this embodiment, the power supply harness 6 is an elastic harness 6, and at least the position of the harness connection part 62 is elastic, so that it can be elastically deformed with the peristalsis of the intestine without applying restrictive pressure to the intestine, providing a retractable movement space for the intestine. When the harness bearing part 61 and the harness connection part 62 are both elastic, the elasticity of the harness connection part 62 is preferably greater than the elasticity of the harness bearing part 61, the harness bearing part 61 can form a more stable connection with the electromagnet 2, the harness connection part 62 has a better elastic deformation force, and can provide a better circumferential expansion space.
如图4所示，所述供电线束6还包括延伸部63，所述延伸部63的一端与所述线束连接部62相连接，所述延伸部63的另一端延伸出体外，所述延伸部63可以与外部电源电连接。As shown in FIG. 4 , the power supply harness 6 further includes an extension portion 63 , one end of which is connected to the harness connection portion 62 , and the other end of which extends out of the body. The extension portion 63 can be electrically connected to an external power source.
在该实施例中，为了方便供电线束6在肠道组织9处的安装和移除，所述供电线束6包括第一连接结构。如图6所示，在所述供电线束6安装于肠道组织9处时，所述供电线束6可在所述第一连接结构处连接而环绕所述肠道组织9的外壁，例如形成闭合的环状结构。所述供电线束6的环状结构也可以在连接端点64处断开，而使得所述供电线束6可以成为一个不封闭的环状或条状结构，从而可以从肠道组织9的外壁处脱离。所述供电线束6的连接端点64处的连接可以是通过卡扣、挂钩、粘接、附加固定件等方式，均属于本发明的保护范围之内。供电线束6可以有两种应用方式：一种方式是供电线束6初始状态是一个封闭的环，在需要从肠道组织9中移除时，将其第一连接结构处断开而脱离所述肠道组织9；另一种方式是供电线束6初始状态是一个不封闭的结构，安装在肠道组织9的外部之后，在连接结构处将其封闭成一个环。In this embodiment, in order to facilitate the installation and removal of the power supply harness 6 at the intestinal tissue 9, the power supply harness 6 includes a first connection structure. As shown in FIG6 , when the power supply harness 6 is installed at the intestinal tissue 9, the power supply harness 6 can be connected at the first connection structure to surround the outer wall of the intestinal tissue 9, for example, to form a closed ring structure. The ring structure of the power supply harness 6 can also be disconnected at the connection end 64, so that the power supply harness 6 can become an unclosed ring or strip structure, so that it can be detached from the outer wall of the intestinal tissue 9. The connection at the connection end 64 of the power supply harness 6 can be by means of snaps, hooks, bonding, additional fixings, etc., all of which belong to the protection scope of the present invention. The power supply harness 6 can be used in two ways: one way is that the power supply harness 6 is initially a closed ring, and when it needs to be removed from the intestinal tissue 9, it is disconnected at the first connection structure and detached from the intestinal tissue 9; the other way is that the power supply harness 6 is initially an unclosed structure, and after being installed outside the intestinal tissue 9, it is closed into a ring at the connection structure.
如图7所示，所述线束承载部61的宽度w11可以大于所述线束连接部62的宽度w13。由此，所述线束承载部61可以承载宽度较宽的电磁铁 2，以实现电磁铁2对保护套1更好的固定作用，并且线束连接部62的宽度较小，可以提高线束连接部62的弹性变形能力，对肠道组织9的蠕动影响大大降低。进一步地，所述线束承载部61的环形壁的宽度w12可以大于所述线束连接部62的宽度w13，提高所述线束承载部61与电磁铁2 的连接稳定性。如图8所示，所述线束承载部61的厚度t11可以与所述线束连接部62的厚度t12基本相等。在另一可替代的实施方式中，所述线束承载部61的厚度t11也可以大于所述线束连接部62的厚度t12，以承载较厚的电磁铁2，并且进一步提高线束连接部62的弹性变形能力，可以提供更好的周向伸缩空间。此处厚度方向即相当于形成环状结构后的供电线束6的径向方向(对应于保护套1的径向方向)。As shown in FIG7 , the width w11 of the harness bearing portion 61 may be greater than the width w13 of the harness connecting portion 62. Thus, the harness bearing portion 61 may bear the electromagnet 2 with a wider width, so as to achieve a better fixing effect of the electromagnet 2 on the protective sleeve 1, and the width of the harness connecting portion 62 is smaller, so as to improve the elastic deformation ability of the harness connecting portion 62, and greatly reduce the peristaltic effect on the intestinal tissue 9. Further, the width w12 of the annular wall of the harness bearing portion 61 may be greater than the width w13 of the harness connecting portion 62, so as to improve the connection stability between the harness bearing portion 61 and the electromagnet 2. As shown in FIG8 , the thickness t11 of the harness bearing portion 61 may be substantially equal to the thickness t12 of the harness connecting portion 62. In another alternative embodiment, the thickness t11 of the harness bearing portion 61 may also be greater than the thickness t12 of the harness connecting portion 62, so as to bear the thicker electromagnet 2, and further improve the elastic deformation ability of the harness connecting portion 62, so as to provide a better circumferential telescopic space. Here, the thickness direction is equivalent to the radial direction of the power supply harness 6 after the ring structure is formed (corresponding to the radial direction of the protective cover 1).
如图3和图4所示，所述电磁铁2与所述肠道组织9相对的表面为弧形表面，该弧形表面的形状与肠道组织9的外壁基本相适应，以实现电磁铁2与肠道组织9的外壁的更好贴合。所述内部固定块3与所述保护套1 相对的表面为弧形表面，该弧形表面的形状与保护套1的内表面基本相适应，以实现内部固定块3与保护套1的内表面的更好贴合。As shown in Fig. 3 and Fig. 4, the surface of the electromagnet 2 opposite to the intestinal tissue 9 is an arcuate surface, and the shape of the arcuate surface is basically adapted to the outer wall of the intestinal tissue 9, so as to achieve a better fit between the electromagnet 2 and the outer wall of the intestinal tissue 9. The surface of the internal fixing block 3 opposite to the protective sleeve 1 is an arcuate surface, and the shape of the arcuate surface is basically adapted to the inner surface of the protective sleeve 1, so as to achieve a better fit between the internal fixing block 3 and the inner surface of the protective sleeve 1.
进一步地，在另一种可替代的实施方式中，所述电磁铁2和/或内部固定块3的表面也可以是波浪形的。具体地，所述电磁铁2朝向所述肠道组织9的表面为沿所述肠道组织9的长度方向(如图3中S方向)有高低起伏的波浪形表面，可以更好地适应于肠道组织9的外壁，增大电磁铁2与肠道组织9的接触面积，提高电磁铁2与肠道组织9的外壁的配合程度。所述内部固定块3朝向所述保护套1的表面为沿所述肠道组织9的长度方向(如图3中S方向)有高低起伏的波浪形表面，增大内部固定块3与保护套1的接触面积，可以提高内部固定块3与保护套1的内壁的配合程度。Furthermore, in another alternative embodiment, the surface of the electromagnet 2 and/or the internal fixing block 3 may also be wavy. Specifically, the surface of the electromagnet 2 facing the intestinal tissue 9 is a wavy surface with ups and downs along the length direction of the intestinal tissue 9 (such as the S direction in FIG. 3 ), which can better adapt to the outer wall of the intestinal tissue 9, increase the contact area between the electromagnet 2 and the intestinal tissue 9, and improve the degree of fit between the electromagnet 2 and the outer wall of the intestinal tissue 9. The surface of the internal fixing block 3 facing the protective sleeve 1 is a wavy surface with ups and downs along the length direction of the intestinal tissue 9 (such as the S direction in FIG. 3 ), which increases the contact area between the internal fixing block 3 and the protective sleeve 1, and can improve the degree of fit between the internal fixing block 3 and the inner wall of the protective sleeve 1.
在该实施例中，所述第一固定组件还包括环绕所述肠道组织9的外壁的第一连接件4，所述第一连接件4包括承载所述电磁铁2的第一承载部 41和连接于相邻两个所述第一承载部41之间的第一连接部42，所述第一承载部41环绕于所述线束承载部61的外部。所述第一连接件4是弹性的，可以随肠道的蠕动发生弹性形变，而不会给肠道施加限制压力，给肠道提供了可伸缩的运动空间。例如，所述第一连接件4可以为橡胶、硅胶等材料制成的具有一定弹性的弹性连接件。在所述第一连接部42和第一承载部41均具有弹性时，所述第一承载部41的弹性可以小于所述第一连接部42的弹性。从而使得第一承载部41更好地固定电磁铁2，第一连接部42可以提供更好的周向伸缩能力。In this embodiment, the first fixing component also includes a first connector 4 surrounding the outer wall of the intestinal tissue 9, the first connector 4 includes a first bearing portion 41 bearing the electromagnet 2 and a first connecting portion 42 connected between two adjacent first bearing portions 41, and the first bearing portion 41 surrounds the outside of the harness bearing portion 61. The first connector 4 is elastic and can be elastically deformed with the peristalsis of the intestine without applying restrictive pressure to the intestine, providing a retractable movement space for the intestine. For example, the first connector 4 can be an elastic connector with a certain elasticity made of rubber, silicone and other materials. When both the first connecting portion 42 and the first bearing portion 41 are elastic, the elasticity of the first bearing portion 41 can be less than the elasticity of the first connecting portion 42. Thereby, the first bearing portion 41 can better fix the electromagnet 2, and the first connecting portion 42 can provide better circumferential telescopic ability.
如图5所示，所述第一连接件4进一步设置有连接结构，所述第一连接件4可在所述第二连接结构处连接而环绕所述肠道组织9的外壁，或者在所述第二连接结构处断开而脱离所述肠道组织9的外壁。图5中示出的连接结构为包括在两个端部分别设置的连接凸起43和连接凹槽44，连接凸起43嵌设于连接凹槽44时，第一连接件4为环状，连接凸起43与连接凹槽44分离时，第一连接件4为条状或其他不封闭的形状。在其他可替代的实施方式中，连接结构也可以采用其他的形式，例如在两个端部分别设置连接环和连接勾，将两者勾在一起或分离实现第一连接件4的两种状态，或者两个端部设置粘接结构，通过粘接或粘接分离实现第一连接件 4的两种状态等等。As shown in FIG5 , the first connecting member 4 is further provided with a connecting structure, and the first connecting member 4 can be connected at the second connecting structure to surround the outer wall of the intestinal tissue 9, or be disconnected at the second connecting structure to detach from the outer wall of the intestinal tissue 9. The connecting structure shown in FIG5 includes a connecting protrusion 43 and a connecting groove 44 respectively provided at two ends, and when the connecting protrusion 43 is embedded in the connecting groove 44, the first connecting member 4 is annular, and when the connecting protrusion 43 is separated from the connecting groove 44, the first connecting member 4 is strip-shaped or other non-closed shapes. In other alternative embodiments, the connecting structure may also take other forms, such as providing a connecting ring and a connecting hook at the two ends respectively, and hooking the two together or separating them to realize two states of the first connecting member 4, or providing an adhesive structure at the two ends, and realizing two states of the first connecting member 4 by bonding or bonding separation, and so on.
如图9所示，所述第一承载部41的宽度w21大于第一连接部42的宽度w23。由此，第一承载部41可以承载宽度较宽的电磁铁2，以实现电磁铁2对保护套1更好的固定作用，并且第一连接部42的宽度较小，可以提高第一连接部42的弹性变形能力，对肠道组织9的蠕动影响大大降低。进一步地，所述第一承载部41的环形壁的宽度w22可以大于第一连接部42的宽度w23，提高第一承载部41与电磁铁2的连接稳定性。在该实施例中，如图10所示，所述第一承载部41的厚度t21和第一连接部42 的厚度t22基本相等。在另一可替代的实施方式中，所述第一承载部41的厚度t21也可以大于第一连接部42的厚度t22。由此，第一承载部41可以承载厚度较厚的电磁铁2，以实现电磁铁2对保护套1更好的固定作用。并且第一连接部42的厚度较小，也可以进一步可以提高第一连接部42的弹性变形能力。此处厚度方向即相当于形成环状结构后的第一连接件4的径向方向(对应于保护套1的径向方向)。As shown in FIG9 , the width w21 of the first bearing portion 41 is greater than the width w23 of the first connecting portion 42. Thus, the first bearing portion 41 can carry the electromagnet 2 with a wider width to achieve a better fixing effect of the electromagnet 2 on the protective cover 1, and the width of the first connecting portion 42 is smaller, which can improve the elastic deformation ability of the first connecting portion 42, and greatly reduce the peristaltic effect on the intestinal tissue 9. Further, the width w22 of the annular wall of the first bearing portion 41 can be greater than the width w23 of the first connecting portion 42, thereby improving the connection stability between the first bearing portion 41 and the electromagnet 2. In this embodiment, as shown in FIG10 , the thickness t21 of the first bearing portion 41 and the thickness t22 of the first connecting portion 42 are substantially equal. In another alternative embodiment, the thickness t21 of the first bearing portion 41 can also be greater than the thickness t22 of the first connecting portion 42. Thus, the first bearing portion 41 can carry the electromagnet 2 with a thicker thickness to achieve a better fixing effect of the electromagnet 2 on the protective cover 1. Furthermore, the first connection portion 42 has a relatively small thickness, which can further improve the elastic deformation capability of the first connection portion 42. The thickness direction here is equivalent to the radial direction of the first connection member 4 after the annular structure is formed (corresponding to the radial direction of the protective sleeve 1).
所述第一承载部41与所述第一连接部42一体成型，且所述第一承载部41为环绕电磁铁2的中空环状结构，即所述第一承载部41中设置有安装孔，电磁铁2嵌设于安装孔中。在其他可替代的实施方式中，所述第一承载部41也可以采用其他的形状，并且也可以与第一连接部42独立成型并固定连接。如图4所示，在所述电磁铁2的侧面上至少部分设置有周向的第一安装槽22，环状的所述第一承载部41嵌设在所述第一安装槽22 中。在另一种可替代的实施方式中，也可以是所述第一承载部41的中空环状结构的边缘内侧至少部分设置有周向的安装槽，所述电磁铁2的侧面嵌设于所述安装槽中，从而实现所述电磁铁2与所述第一承载部41的稳定连接。在该实施例中，所述第一承载部41位于所述供电线束6的线束承载部61的外侧。The first bearing portion 41 and the first connecting portion 42 are integrally formed, and the first bearing portion 41 is a hollow annular structure surrounding the electromagnet 2, that is, a mounting hole is provided in the first bearing portion 41, and the electromagnet 2 is embedded in the mounting hole. In other alternative embodiments, the first bearing portion 41 may also adopt other shapes, and may also be independently formed and fixedly connected with the first connecting portion 42. As shown in Figure 4, a circumferential first mounting groove 22 is at least partially provided on the side of the electromagnet 2, and the annular first bearing portion 41 is embedded in the first mounting groove 22. In another alternative embodiment, the inner side of the edge of the hollow annular structure of the first bearing portion 41 may also be at least partially provided with a circumferential mounting groove, and the side of the electromagnet 2 is embedded in the mounting groove, so as to achieve a stable connection between the electromagnet 2 and the first bearing portion 41. In this embodiment, the first bearing portion 41 is located on the outside of the harness bearing portion 61 of the power supply harness 6.
所述第一连接件4可以部分或全部采用生物可吸收材料，例如采用生物可吸收的医用薄膜制成，在保证一定强度的情况下具有柔性或具有一定的弹性。从而省去了第二连接件5在术后移除的步骤。The first connecting member 4 may be partially or completely made of bioabsorbable material, such as a bioabsorbable medical film, which is flexible or elastic while ensuring a certain strength, thereby eliminating the need to remove the second connecting member 5 after surgery.
如图3所示，还可以进一步在保护套1的内表面设置有与所述内部固定块3一一对应的凹槽12，以更好地实现内部固定块3在保护套1内表面的定位。所述内部固定块3嵌设于所对应的凹槽12中，从而实现内部固定块3与保护套1的内表面的可拆卸固定。As shown in FIG3 , a groove 12 corresponding to the internal fixing block 3 may be further provided on the inner surface of the protective cover 1 to better position the internal fixing block 3 on the inner surface of the protective cover 1. The internal fixing block 3 is embedded in the corresponding groove 12, thereby realizing the detachable fixation of the internal fixing block 3 and the inner surface of the protective cover 1.
在该实施例中，所述内部固定块3可以部分或全部采用生物可吸收材料，例如采用生物可吸收铁基材料，或者磁化的生物可吸收铁基材料等等，从而省去了内部固定块3在术后移除的步骤。In this embodiment, the internal fixation block 3 may be partially or completely made of bioabsorbable materials, such as bioabsorbable iron-based materials, or magnetized bioabsorbable iron-based materials, etc., thereby eliminating the step of removing the internal fixation block 3 after surgery.
如图11所示，为本发明第二实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中，所述第一固定组件不包括第一连接件。供电线束6可以同时起到固定电磁铁2和为电磁铁2供电的作用。所述供电线束6可以采用上述第一实施例中的具体结构，但本发明不限于此。在其他可替代的实施方式中，所述供电线束6可以设计为其他结构，与电磁铁2可以通过其他方式连接，均属于本发明的保护范围之内。As shown in Figure 11, it is a schematic diagram of the structure of the anastomotic protection device of the second embodiment of the present invention applied to intestinal tissue. In this embodiment, the first fixing component does not include a first connecting member. The power supply harness 6 can simultaneously fix the electromagnet 2 and supply power to the electromagnet 2. The power supply harness 6 can adopt the specific structure of the above-mentioned first embodiment, but the present invention is not limited to this. In other alternative embodiments, the power supply harness 6 can be designed as other structures, and can be connected to the electromagnet 2 in other ways, all of which are within the protection scope of the present invention.
如图12所示，为本发明第三实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中，所述吻合口保护装置可以用于肠道高位的吻合口保护。在吻合口的上游一侧的肠道组织9外壁设置有一组电磁铁 2，对应地保护套1内部设置有内部固定块，在吻合口的下游一侧的肠道组织9外壁设置有另一组电磁铁2，对应地在保护套1内部设置有内部固定块。该种结构一方面可以大大节省了所需要的保护套1的长度，并且更方便手术过程中保护套1的放置和吻合口恢复后保护套1的移除，另一方面可以更好地将保护套1固定在需要的位置，保证使用过程中的稳定性。As shown in Figure 12, it is a schematic diagram of the structure of the anastomotic protection device of the third embodiment of the present invention applied to intestinal tissue. In this embodiment, the anastomotic protection device can be used for anastomotic protection at a high position of the intestine. A group of electromagnets 2 are arranged on the outer wall of the intestinal tissue 9 on the upstream side of the anastomosis, and an internal fixing block is correspondingly arranged inside the protective sleeve 1. Another group of electromagnets 2 are arranged on the outer wall of the intestinal tissue 9 on the downstream side of the anastomosis, and an internal fixing block is correspondingly arranged inside the protective sleeve 1. On the one hand, this structure can greatly save the required length of the protective sleeve 1, and is more convenient for the placement of the protective sleeve 1 during surgery and the removal of the protective sleeve 1 after the anastomosis is restored. On the other hand, the protective sleeve 1 can be better fixed in the required position to ensure stability during use.
如图13～16所示，为本发明第四实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中，所述第二固定组件还包括第二连接件 5。所述第二连接件5安装于所述肠道组件9处时，所述第二连接件5环绕所述保护套1的内表面，而形成一个连接环状结构，从而与所述内部固定块3一起对保护套1形成一个周向的固定。所述第二连接件5与所述第一连接件4的位置相对应，形成对保护套1的固定环。如图14所示，所述第二连接件5包括第二承载部51和第二连接部52。所述第二承载部51 与内部固定块3一一对应，且承载所对应的内部固定块3。所述第二连接部52连接于相邻两个所述第二承载部51之间。所述第二连接件5安装于所述肠道组件9处时，所述第二连接件5是周向可伸缩的。进一步地，所述第二连接件5可以为弹性连接件，至少其第二连接部52是具有弹性的。因此，在肠道蠕动时，第二连接件5可以随肠道的蠕动发生弹性形变，而不会给肠道施加限制压力，给肠道提供了可伸缩的运动空间。例如，所述第二连接件5可以为橡胶、硅胶等材料制成的具有一定弹性的弹性连接件。所述第二连接件5可以平行于支撑部11设置。所述第二连接件5可以是一个封闭的环状结构，也可以是一个具有接口的连接件，安装于所述肠道组件9处时，首尾相接形成连接环。在所述第二连接部52和第二承载部51均具有弹性时，所述第二承载部51的弹性可以小于所述第二连接部52的弹性。从而使得第二承载部51更好地固定内部固定块3，第二连接部52可以提供更好的周向伸缩能力。As shown in Figures 13 to 16, it is a schematic diagram of the structure of the anastomotic protection device of the fourth embodiment of the present invention applied to intestinal tissue. In this embodiment, the second fixing component also includes a second connecting member 5. When the second connecting member 5 is installed at the intestinal component 9, the second connecting member 5 surrounds the inner surface of the protective sleeve 1 to form a connecting ring structure, thereby forming a circumferential fixation of the protective sleeve 1 together with the internal fixing block 3. The second connecting member 5 corresponds to the position of the first connecting member 4 to form a fixing ring for the protective sleeve 1. As shown in Figure 14, the second connecting member 5 includes a second bearing portion 51 and a second connecting portion 52. The second bearing portion 51 corresponds to the internal fixing block 3 one by one and carries the corresponding internal fixing block 3. The second connecting portion 52 is connected between two adjacent second bearing portions 51. When the second connecting member 5 is installed at the intestinal component 9, the second connecting member 5 is circumferentially retractable. Further, the second connecting member 5 can be an elastic connecting member, at least its second connecting portion 52 is elastic. Therefore, when the intestine moves, the second connecting member 5 can be elastically deformed with the movement of the intestine without applying restrictive pressure to the intestine, providing the intestine with a retractable movement space. For example, the second connecting member 5 can be an elastic connecting member with a certain elasticity made of rubber, silicone or other materials. The second connecting member 5 can be arranged parallel to the support portion 11. The second connecting member 5 can be a closed annular structure, or a connecting member with an interface, which is connected end to end to form a connecting ring when installed at the intestinal component 9. When the second connecting portion 52 and the second bearing portion 51 are both elastic, the elasticity of the second bearing portion 51 can be less than the elasticity of the second connecting portion 52. Thereby, the second bearing portion 51 can better fix the internal fixing block 3, and the second connecting portion 52 can provide better circumferential telescopic capability.
进一步地，所述第二连接件5可以部分或全部采用生物可吸收材料，例如采用生物可吸收的医用薄膜制成，在保证一定强度的情况下具有柔性或具有一定的弹性。从而省去了第二连接件5在术后移除的步骤。Furthermore, the second connecting member 5 may be partially or entirely made of bioabsorbable material, such as a bioabsorbable medical film, which is flexible or elastic while ensuring a certain strength, thereby eliminating the need for removing the second connecting member 5 after surgery.
如图15所示，在该实施例中，所述第二承载部51的宽度w31大于第二连接部52的宽度w33。由此，第二承载部51可以承载宽度较宽的内部固定块3，以实现内部固定块3对保护套1更好的固定作用，并且第二连接部52的宽度较小，可以提高第二连接部52的弹性变形能力，对肠道组织9的蠕动影响大大降低。进一步地，所述第二承载部51的环形壁的宽度w32可以大于第二连接部42的宽度w33，提高第二承载部51与内部固定块3的连接稳定性。在该实施例中，如图16所示，所述第二承载部51的厚度t31和第二连接部52的厚度t32基本相等。在另一可替代的实施方式中，所述第二承载部51的厚度t31也可以大于第二连接部52的厚度t32。由此，第二承载部51可以承载厚度较厚的内部固定块3，以实现内部固定块3对保护套1更好的固定作用。并且第二连接部52的厚度较小，也可以进一步可以提高第二连接部52的弹性变形能力。As shown in FIG. 15 , in this embodiment, the width w31 of the second bearing portion 51 is greater than the width w33 of the second connecting portion 52. Thus, the second bearing portion 51 can bear the internal fixing block 3 with a wider width, so as to achieve a better fixing effect of the internal fixing block 3 on the protective sleeve 1, and the width of the second connecting portion 52 is smaller, which can improve the elastic deformation ability of the second connecting portion 52, and greatly reduce the peristaltic effect on the intestinal tissue 9. Further, the width w32 of the annular wall of the second bearing portion 51 can be greater than the width w33 of the second connecting portion 42, so as to improve the connection stability between the second bearing portion 51 and the internal fixing block 3. In this embodiment, as shown in FIG. 16 , the thickness t31 of the second bearing portion 51 and the thickness t32 of the second connecting portion 52 are substantially equal. In another alternative embodiment, the thickness t31 of the second bearing portion 51 can also be greater than the thickness t32 of the second connecting portion 52. Thus, the second bearing portion 51 can bear the internal fixing block 3 with a thicker thickness, so as to achieve a better fixing effect of the internal fixing block 3 on the protective sleeve 1. Furthermore, the thickness of the second connection portion 52 is relatively small, and the elastic deformation capability of the second connection portion 52 can be further improved.
如图14所示，所述第二承载部51与所述第二连接部52一体成型，且所述第二承载部51为环绕内部固定块3的中空环状结构，即所述第二承载部51中设置有安装孔，内部固定块3嵌设于安装孔中。为了更方便地将内部固定块3安装于第二连接件5和从第二连接件5中移除，所述内部固定块3与所述安装孔的内壁相贴的各个侧壁具有圆角31结构。在其他可替代的实施方式中，所述第二承载部51也可以采用其他的形状，并且也可以与第二连接部52独立成型并固定连接。如图14所示，在所述内部固定块3的侧面上至少部分设置有周向的第二安装槽32，环状的所述第二承载部51嵌设在所述第二安装槽32中。在另一种可替代的实施方式中，也可以是所述第二承载部51的中空环状结构的边缘内侧至少部分设置有第二固定块周向的第二安装槽，所述内部固定块3的侧面嵌设于所述第二安装槽中，从而实现所述内部固定块3与所述第二承载部51的稳定连接。As shown in FIG. 14 , the second bearing portion 51 and the second connecting portion 52 are integrally formed, and the second bearing portion 51 is a hollow annular structure surrounding the internal fixing block 3, that is, a mounting hole is provided in the second bearing portion 51, and the internal fixing block 3 is embedded in the mounting hole. In order to more conveniently install the internal fixing block 3 on the second connecting member 5 and remove it from the second connecting member 5, each side wall of the internal fixing block 3 that is in contact with the inner wall of the mounting hole has a rounded corner 31 structure. In other alternative embodiments, the second bearing portion 51 may also adopt other shapes, and may also be independently formed and fixedly connected to the second connecting portion 52. As shown in FIG. 14 , a circumferential second mounting groove 32 is at least partially provided on the side surface of the internal fixing block 3, and the annular second bearing portion 51 is embedded in the second mounting groove 32. In another alternative embodiment, a second mounting groove circumferentially arranged on the inner side of the edge of the hollow annular structure of the second bearing portion 51 may be provided with at least a portion of a second mounting groove of the second fixing block, and the side surface of the internal fixing block 3 may be embedded in the second mounting groove, thereby achieving a stable connection between the internal fixing block 3 and the second bearing portion 51.
在该实施例中，所述第二连接件5也可以与所述保护套1一体成型。在一种可替代的实施方式中，所述第二连接件5也可以是与所述保护套1 分别成型后通过黏贴等方式固定在一起的。在另一种可替代的实施方式中，所述第二连接件5也可以是未提前固定在保护套1中，而是在手术时由医生放入到保护套1的对应位置。In this embodiment, the second connecting member 5 may also be integrally formed with the protective cover 1. In an alternative embodiment, the second connecting member 5 may also be separately formed from the protective cover 1 and fixed together by gluing or the like. In another alternative embodiment, the second connecting member 5 may not be fixed in advance in the protective cover 1, but may be placed in the corresponding position of the protective cover 1 by the doctor during surgery.
如图17所示，为本发明第五实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中，所述第二固定组件包括涂覆于所述保护套1的内表面的磁性颗粒涂层8，所述磁性颗粒涂层8的位置与所述电磁铁2相对应，磁性颗粒涂层8的磁性与电磁铁2通电时的磁性相反。磁性颗粒涂层8可以通过将磁性颗粒与粘合剂、溶剂等制成磁浆，涂布在保护套1的内表面。因此，第二固定组件与保护套1形成为一体结构，手术时可以一起放到肠道组织9内部需要的位置，术后吻合口恢复后可以一起从肠道组织9中取出。该实施例的第二固定组件结构也可以与上述各个实施例的电磁铁2的结构进行组合。同样地，通过控制磁性颗粒的分布密度和磁性颗粒的总数量，可以实现控制电磁铁2和磁性颗粒涂层8之间磁性吸附力大小的目的。并且，磁性颗粒涂层8与保护套1一体设置，省去了将第二固定组件安装到保护套1上和从保护套1中移除的步骤。并且，第二固定组件采用磁性颗粒涂层的方式，在保护套1的内部占用的空间更小。As shown in FIG. 17 , it is a schematic diagram of the structure of the anastomotic stoma protection device of the fifth embodiment of the present invention applied to intestinal tissue. In this embodiment, the second fixing component includes a magnetic particle coating 8 coated on the inner surface of the protective sleeve 1, and the position of the magnetic particle coating 8 corresponds to the electromagnet 2, and the magnetism of the magnetic particle coating 8 is opposite to the magnetism of the electromagnet 2 when it is energized. The magnetic particle coating 8 can be made into a magnetic slurry by mixing magnetic particles with adhesives, solvents, etc., and applied on the inner surface of the protective sleeve 1. Therefore, the second fixing component and the protective sleeve 1 form an integrated structure, which can be placed together at the required position inside the intestinal tissue 9 during surgery, and can be taken out from the intestinal tissue 9 together after the anastomosis is restored after surgery. The second fixing component structure of this embodiment can also be combined with the structure of the electromagnet 2 of each of the above embodiments. Similarly, by controlling the distribution density of the magnetic particles and the total number of magnetic particles, the purpose of controlling the magnitude of the magnetic adsorption force between the electromagnet 2 and the magnetic particle coating 8 can be achieved. In addition, the magnetic particle coating 8 is integrally arranged with the protective sleeve 1, eliminating the steps of installing the second fixing component on the protective sleeve 1 and removing it from the protective sleeve 1. In addition, the second fixing component adopts the method of magnetic particle coating, which occupies less space inside the protective sleeve 1.
如图18所示，为本发明第六实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中，全部或者部分所述内部固定块3的表面涂覆有磁性颗涂层或内部分布有磁性颗粒。各个所述内部固定块3的磁性颗粒磁性相同，且与所述电磁铁2的磁性相反。As shown in FIG18 , it is a schematic diagram of the structure of the anastomotic stoma protection device according to the sixth embodiment of the present invention applied to intestinal tissue. In this embodiment, the surface of all or part of the internal fixing block 3 is coated with a magnetic particle coating or magnetic particles are distributed inside. The magnetic particles of each internal fixing block 3 have the same magnetic properties and are opposite to the magnetic properties of the electromagnet 2.
本发明所提供的吻合口保护装置的各实施例的材质均为满足生物相容性的材质。The materials of the various embodiments of the anastomotic stoma protection device provided by the present invention are all materials that meet biocompatibility requirements.
本发明所提供的吻合口保护装置具有如下优点：The anastomotic stoma protection device provided by the present invention has the following advantages:

By setting the electromagnetic generating component and the power supply component, the presence or absence of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the on and off of the power supply, and the magnitude of magnetism in the electromagnetic generating component can be flexibly controlled by controlling the magnitude of the power supply current. The tubular tissue used in the anastomotic protection device of the present invention can be the intestine, or it can be other tubular tissues in the human body, such as tubular tissues in other positions in the digestive tract.
