技术领域Technical Field
本发明涉及医疗器械技术领域，具体涉及一种基于磁性颗粒的吻合口保护组件。The invention relates to the technical field of medical devices, and in particular to an anastomotic stoma protection component based on magnetic particles.
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 position of the inner surface of the intestine corresponding to 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, the sleeve can be directly removed without a second operation. 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.

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1～4所示，为本发明第一实施例的基于磁性颗粒的吻合口保护组件的结构示意图。在该实施例中，所述基于磁性颗粒的吻合口保护组件包括：保护套1，位于所述肠道组件9的内部与所述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；第一固定部件，设置于所述肠道组件9的外壁；以及第二固定部件，设置于所述保护套1的内表面与所述第一固定部件相对应的位置。所述保护套1位于肠道组织9内部与吻合口相对应的位置，即保护套1的两端分别位于吻合口的两侧，全面覆盖吻合口，所述吻合口保护组件贴合被保护组织的组织壁。所述保护套1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。As shown in Figures 1 to 4, it is a schematic diagram of the structure of the anastomotic stoma protection component based on magnetic particles according to the first embodiment of the present invention. In this embodiment, the anastomotic stoma protection component based on magnetic particles includes: a protective sleeve 1, which is located in the position corresponding to the anastomotic stoma inside the intestinal component 9, and protects the inner surface of the anastomotic stoma, and does not contaminate the anastomotic stoma during the process of guiding the intestinal contents to pass through; a first fixing component, which is arranged on the outer wall of the intestinal component 9; and a second fixing component, which is arranged on the inner surface of the protective sleeve 1 at a position corresponding to the first fixing component. The protective sleeve 1 is located in the intestinal tissue 9 at a position corresponding to the anastomotic stoma, that is, the two ends of the protective sleeve 1 are respectively located on both sides of the anastomotic stoma, fully covering the anastomotic stoma, and the anastomotic stoma protection component adheres to the tissue wall of the protected tissue. The protective sleeve 1 protects the inner surface of the anastomotic stoma, and does not contaminate the anastomotic stoma during the process of guiding the intestinal contents to pass through.
为了实现所述保护套1的固定，所述第一固定部件包括第一吸引部，所述第二固定部件中包括第二吸引部，且所述第一吸引部与所述第二吸引部通过磁性吸附而相对固定。所述第一吸引部和/或所述第二吸引部中分布有磁性颗粒。为了实现第一吸引部和第二吸引部分的相互磁性吸附，所述第一吸引部的位置与所述第二吸引部的位置相对应，相对应的一组所述第一吸引部和所述第二吸引部均具有磁性，或一个具有磁性，另一个不具有磁性而可被磁性吸引。具有磁性的吸引部例如可以采用分布有磁性颗粒的形式，或者采用本身具有磁性的材料，而不具有磁性而可被磁性吸引则可以采用如铁、镍等亲磁性金属。在该实施例中，第一磁性部和第二磁性部均分布有磁性颗粒。但本发明不限于此，在其他实施例中，也可以第一磁性部分布有磁性颗粒，第二磁性部没有磁性颗粒，或者第一磁性部没有磁性颗粒，第二磁性部分布有磁性颗粒，或者部分第一磁性部分布有磁性颗粒，部分第二磁性部分布有磁性颗粒等等，均属于本发明的保护范围之内。In order to achieve the fixation of the protective cover 1, the first fixing component includes a first attraction part, the second fixing component includes a second attraction part, and the first attraction part and the second attraction part are relatively fixed by magnetic adsorption. Magnetic particles are distributed in the first attraction part and/or the second attraction part. In order to achieve the mutual magnetic adsorption of the first attraction part and the second attraction part, the position of the first attraction part corresponds to the position of the second attraction part, and a corresponding set of the first attraction part and the second attraction part are both magnetic, or one is magnetic and the other is not magnetic but can be attracted by magnetism. The magnetic attraction part can, for example, be in the form of distributed magnetic particles, or a material that is magnetic itself, while a non-magnetic but magnetically attracted metal such as iron and nickel can be used. In this embodiment, magnetic particles are distributed in the first magnetic part and the second magnetic part. However, the present invention is not limited to this. In other embodiments, the first magnetic part can be distributed with magnetic particles, the second magnetic part has no magnetic particles, or the first magnetic part has no magnetic particles, the second magnetic part has magnetic particles, or part of the first magnetic part is distributed with magnetic particles, part of the second magnetic part is distributed with magnetic particles, etc., all of which belong to the protection scope of the present invention.
如图2所示，在该实施例中，所述第一吸引部和所述第二吸引部中均分布有磁性颗粒，所述第一吸引部中的磁性颗粒磁性相同，所述第二吸引部中的磁性颗粒磁性相同，且所述所述第一吸引部中的磁性颗粒和所述第二吸引部中的磁性颗粒磁性相反。As shown in Figure 2, in this embodiment, magnetic particles are distributed in both the first attraction part and the second attraction part, the magnetic particles in the first attraction part have the same magnetic properties, the magnetic particles in the second attraction part have the same magnetic properties, and the magnetic particles in the first attraction part and the magnetic particles in the second attraction part have opposite magnetic properties.
所述外部磁性颗粒6可以以第一磁性颗粒涂层的形式涂覆于所述第一磁性部件的表面，例如涂覆于所述第一吸引部朝向所述肠道组件9的内表面。磁性颗粒可以与粘合剂、溶剂等制成磁性颗粒涂层，涂布在塑料或金属片基的表面。所述外部磁性颗粒6也可以以磁性颗粒掺杂的形式形成于所述第一吸引部中。所述内部磁性颗粒7可以以第二磁性颗粒涂层的形式涂覆于所述第二吸引部的表面，例如涂覆于所述第二吸引部朝向所述保护套1的外表面。磁性颗粒可以与粘合剂、溶剂等制成磁性颗粒涂层，涂布在塑料或金属片基的表面。所述内部磁性颗粒7也可以以磁性颗粒掺杂的形式形成于所述第二吸引部中。本发明的各个视图中的磁性颗粒的尺寸和分布方式仅为示例，实际应用中所采用的磁性颗粒的尺寸可以大于或小于图中示出的示例，磁性颗粒的分布可以是均匀分布，也可以是不均匀分布，均属于本发明的保护范围之内。The external magnetic particles 6 can be coated on the surface of the first magnetic component in the form of a first magnetic particle coating, for example, coated on the inner surface of the first attraction portion facing the intestinal component 9. Magnetic particles can be made into a magnetic particle coating with adhesives, solvents, etc., and coated on the surface of a plastic or metal sheet base. The external magnetic particles 6 can also be formed in the first attraction portion in the form of magnetic particle doping. The internal magnetic particles 7 can be coated on the surface of the second attraction portion in the form of a second magnetic particle coating, for example, coated on the outer surface of the second attraction portion facing the protective sleeve 1. Magnetic particles can be made into a magnetic particle coating with adhesives, solvents, etc., and coated on the surface of a plastic or metal sheet base. The internal magnetic particles 7 can also be formed in the second attraction portion in the form of magnetic particle doping. The size and distribution of the magnetic particles in the various views of the present invention are only examples. The size of the magnetic particles used in actual applications can be larger or smaller than the examples shown in the figures, and the distribution of the magnetic particles can be uniform or uneven, all of which fall within the scope of protection of the present invention.
如图1～3所示，所述第一吸引部包括第一固定块2，所述第二吸引部包括第二固定块3。所述第一固定块2设置于肠道组织9的外壁，所述第二固定块3设置于所述保护套1的内表面与所述第一固定块2相对应的位置，且所述第一固定块2和所述第二固定块3通过磁性吸附而相对固定，从而通过第一固定块2和第二固定块3的固定来保持保护套1相对于肠道组织9的位置。As shown in Figs. 1 to 3, the first suction part includes a first fixing block 2, and the second suction part includes a second fixing block 3. The first fixing block 2 is arranged on the outer wall of the intestinal tissue 9, and the second fixing block 3 is arranged on the inner surface of the protective sleeve 1 at a position corresponding to the first fixing block 2, and the first fixing block 2 and the second fixing block 3 are relatively fixed by magnetic adsorption, so that the position of the protective sleeve 1 relative to the intestinal tissue 9 is maintained by fixing the first fixing block 2 and the second fixing block 3.
所述第一固定部件和第二固定部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。在该吻合口保护组件应用于肠道低位时，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 first fixing component and the second fixing component are preferably arranged 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 the 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 as a reference, and the intestinal contents move along the intestine from the upstream side of the anastomosis to the downstream side of the anastomosis. When the anastomosis protection component 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.
由于该组件中只有第一固定块2和第二固定块3之间的磁性吸附位置是相对固定的，给肠道提供充足的周向伸缩的空间，保证吻合口附近正常的供血。在肠道组织9蠕动时，第一固定块2和第二固定块3可随肠道组织9蠕动而运动，相邻的两个第一固定块2之间的距离可以发生变化，相邻两个第二固定块3之间的距离也可以发生变化，从而使得吻合口保护组件整体形成一个周向可伸缩的结构。Since only the magnetic adsorption position between the first fixing block 2 and the second fixing block 3 is relatively fixed in the assembly, sufficient circumferential expansion space is provided for the intestine to ensure normal blood supply near the anastomosis. When the intestinal tissue 9 moves, the first fixing block 2 and the second fixing block 3 can move with the intestinal tissue 9, and the distance between two adjacent first fixing blocks 2 can change, and the distance between two adjacent second fixing blocks 3 can also change, so that the anastomosis protection assembly as a whole forms a circumferentially expandable structure.
如图2所示，在该实施例中，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 , in this embodiment, 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.
如图1和图2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，实现保护套1更好的与肠壁贴合密封，防止内容物进入吻合口处。支撑部11可以采用可充气放气的环形弹性气囊，该气囊的外壁具有弹性，例如可以是弹性橡胶、硅胶、TPU等，或者是薄的PC材质，在充气后与组织壁贴合，在有内容物经过时，周向长度可以变大，可好地贴合肠道。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。所述第一固定部件和第二固定部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 1 and 2, the protective sleeve 1 is provided with a support portion 11 at one end 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 or taken out from the intestinal tissue 9 as a whole. 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, so that the protective sleeve 1 can better fit and seal with the intestinal wall to prevent the contents from entering the anastomosis. The support portion 11 can adopt an inflatable and deflated annular elastic airbag, the outer wall of which is elastic, for example, it can be elastic rubber, silicone, TPU, etc., or a thin PC material, which fits with the tissue wall after inflation. When the contents pass through, the circumferential length can be enlarged, and the intestine can be well fitted. The support portion 11 can also adopt other radially retractable springs or radially movable slider structures, which can increase or reduce the outer diameter of the support portion 11. The first fixing component and the second fixing component are disposed between the anastomotic opening and the supporting portion 11 , and can better maintain the protective sleeve 1 at the anastomotic opening position by cooperating with the supporting portion 11 .
如图2和图3所示，所述组件包括多个所述第一固定块2和多个所述第二固定块3，所述第一固定块2和所述第二固定块3分别沿所述肠道组织9的周向依次排列，以对所述保护套1形成一个均匀、稳定的固定。在该实施例中，多个所述第一固定块2之间设有间隔，多个所述第二固定块3之间设有间隔。所述第一固定块2和第二固定块3的数量也可以根据需要选择设置，并且第一固定块2和第二固定块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，第一固定块2也可以设置为1个和/或第二固定块3也可以设置为1个。As shown in Figures 2 and 3, the component includes a plurality of first fixing blocks 2 and a plurality of second fixing blocks 3, and the first fixing blocks 2 and the second fixing blocks 3 are respectively arranged in sequence along the circumference of the intestinal tissue 9 to form a uniform and stable fixation for the protective sleeve 1. In this embodiment, a plurality of first fixing blocks 2 are provided with intervals, and a plurality of second fixing blocks 3 are provided with intervals. The number of the first fixing blocks 2 and the second fixing blocks 3 can also be selected and set as needed, and a one-to-one relationship, a one-to-many relationship, or a many-to-one relationship, etc. can be formed between the first fixing blocks 2 and the second fixing blocks 3, all of which fall within the scope of protection of the present invention. In other alternative embodiments, the first fixing block 2 can also be set to 1 and/or the second fixing block 3 can also be set to 1.
如图2所示，所述第一固定块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，以实现第一固定块2与肠道组织9的外壁的更好贴合。所述第二固定块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，以实现第二固定块3与保护套1的内表面的更好贴合。As shown in Fig. 2, the surface of the first fixing block 2 opposite to the intestinal tissue 9 is an arcuate surface, the shape of which is substantially adapted to the outer wall of the intestinal tissue 9, so as to achieve a better fit between the first fixing block 2 and the outer wall of the intestinal tissue 9. The surface of the second fixing block 3 opposite to the protective sleeve 1 is an arcuate surface, the shape of which is substantially adapted to the inner surface of the protective sleeve 1, so as to achieve a better fit between the second 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，所述第一固定块2和/或第二固定块3的表面也可以是波浪形的。具体地，所述第一固定块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2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，增大第一固定块2与肠道组织9的接触面积，提高第一固定块2与肠道组织9的外壁的配合程度。所述第二固定块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2中S方向)有高低起伏的波浪形表面，增大第二固定块3与保护套1的接触面积，可以提高第二固定块3与保护套1的内壁的配合程度。Furthermore, in another alternative embodiment, the surface of the first fixing block 2 and/or the second fixing block 3 may also be wavy. Specifically, the surface of the first fixing block 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. 2 ), which can better adapt to the outer wall of the intestinal tissue 9, increase the contact area between the first fixing block 2 and the intestinal tissue 9, and improve the degree of fit between the first fixing block 2 and the outer wall of the intestinal tissue 9. The surface of the second 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. 2 ), which increases the contact area between the second fixing block 3 and the protective sleeve 1, and can improve the degree of fit between the second fixing block 3 and the inner wall of the protective sleeve 1.
如图2和图3所示，所述第一固定部件还包括承载所述第一固定块2的第一连接件4，所述第一连接件4在安装于所述肠道组件9处时，所述第一连接件4环绕所述肠道组织9的外壁，形成一个连接环状结构，从而与所述第一固定块2一起对保护套1形成一个周向的固定。所述第一连接件4包括第一承载部41和第一连接部42。所述第一承载部41与第一固定块2一一对应，且承载所对应的第一固定块2。所述第一连接部42连接于相邻两个所述第一承载部41之间。所述第一连接件4环绕所述肠道组件9的外壁时，所述第一连接件4是周向可伸缩的。进一步地，所述第一连接件4可以为弹性连接件，至少其第一连接部42是具有弹性的。因此，在肠道蠕动时，第一连接件4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。所述第一连接件4可以平行于支撑部11设置。As shown in Figures 2 and 3, the first fixing component also includes a first connector 4 that carries the first fixing block 2. When the first connector 4 is installed at the intestinal component 9, the first connector 4 surrounds the outer wall of the intestinal tissue 9 to form a connecting ring structure, thereby forming a circumferential fixation of the protective sleeve 1 together with the first fixing block 2. The first connector 4 includes a first bearing portion 41 and a first connecting portion 42. The first bearing portion 41 corresponds to the first fixing block 2 one by one and carries the corresponding first fixing block 2. The first connecting portion 42 is connected between two adjacent first bearing portions 41. When the first connector 4 surrounds the outer wall of the intestinal component 9, the first connector 4 is circumferentially retractable. Further, the first connector 4 can be an elastic connector, at least its first connecting portion 42 is elastic. Therefore, when the intestine moves, the first connector 4 can be elastically deformed with the movement 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 materials such as rubber and silicone. The first connecting member 4 may be disposed parallel to the supporting portion 11 .
如图4所示，所述第一连接件4可以进一步设置有连接结构，所述第一连接件4可在所述连接结构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，或者在所述连接结构处断开而脱离所述肠道组织9的外壁。即第一连接件4可以有两种状态：封闭的环状或不封闭形状。第一连接件4可以有两种应用方式：一种方式是第一连接件4初始状态是一个封闭的环，在需要从肠道组织9中移除时，将其连接结构处断开而脱离所述肠道组织9；另一种方式是第一连接件4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。图4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。在需要将第一固定块2放置于肠道组织9的外壁时，可以将第一连接件4和第一固定块2作为一个整体一起放入到腹腔中去，此时第一连接件4是一个不封闭的环，或者是一个长条形结构，其具有两个端部，并且将第一连接件4环绕肠道组织9的外壁后，将第一连接件4的两个端部彼此连接而形成具有接口的封闭的环形。该接口处的连接可以通过卡接、附加固定件的连接等方式。As shown in FIG. 4 , the first connector 4 may be further provided with a connecting structure, and the first connector 4 may be connected to the connecting structure to surround the outer wall of the intestinal tissue 9, for example, to form a closed ring structure, or be disconnected at the connecting structure to detach from the outer wall of the intestinal tissue 9. That is, the first connector 4 may have two states: a closed ring or an open shape. The first connector 4 may be used in two ways: one way is that the first connector 4 is initially a closed ring, and when it needs to be removed from the intestinal tissue 9, it is disconnected at the connecting structure to detach from the intestinal tissue 9; the other way is that the first connector 4 is initially an open structure, and after being installed on the outside of the intestinal tissue 9, it is closed into a ring at the connecting structure. The connecting structure shown in FIG. 4 includes a connecting protrusion 43 and a connecting groove 44 respectively arranged at two ends. When the connecting protrusion 43 is embedded in the connecting groove 44, the first connector 4 is annular, and when the connecting protrusion 43 is separated from the connecting groove 44, the first connector 4 is strip-shaped or other open shapes. In other alternative embodiments, the connection structure may also be in other forms, for example, a connection ring and a connection hook are respectively provided at the two ends, and the two are hooked together or separated to realize the two states of the first connection member 4, or an adhesive structure is provided at the two ends, and the two states of the first connection member 4 are realized by bonding or bonding separation, etc. When the first fixing block 2 needs to be placed on the outer wall of the intestinal tissue 9, the first connection member 4 and the first fixing block 2 can be put into the abdominal cavity as a whole. At this time, the first connection member 4 is an unclosed ring, or a long strip structure, which has two ends, and after the first connection member 4 is wrapped around the outer wall of the intestinal tissue 9, the two ends of the first connection member 4 are connected to each other to form a closed ring with an interface. The connection at the interface can be achieved by means of snap connection, connection with additional fixings, etc.
如图3所示，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为环绕第一固定块2的中空环状结构，即所述第一承载部41中设置有安装孔，第一固定块2嵌设于安装孔中。为了更方便地将第一固定块2安装于第一连接件4和从第一连接件4中移除，所述第一固定块2与所述安装孔的内壁相贴的各个侧壁具有圆角21结构。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3所示，在所述第一固定块2的侧面上至少部分设置有周向的第一固定块安装槽22，环状的所述第一承载部41嵌设在所述第一固定块安装槽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第一固定块安装槽，所述第一固定块2的侧面嵌设于所述第一固定块安装槽中，从而实现所述第一固定块2与所述第一承载部41的稳定连接。As shown in FIG3 , 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 first fixed block 2, that is, a mounting hole is provided in the first bearing portion 41, and the first fixed block 2 is embedded in the mounting hole. In order to more conveniently install the first fixed block 2 on the first connecting member 4 and remove it from the first connecting member 4, each side wall of the first fixed block 2 that is in contact with the inner wall of the mounting hole has a rounded corner 21 structure. In other alternative embodiments, the first bearing portion 41 may also adopt other shapes, and may also be independently formed and fixedly connected to the first connecting portion 42. As shown in FIG3 , a circumferential first fixed block mounting groove 22 is at least partially provided on the side surface of the first fixed block 2, and the annular first bearing portion 41 is embedded in the first fixed block 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 be at least partially provided with a circumferential first fixing block mounting groove, and the side surface of the first fixing block 2 may be embedded in the first fixing block mounting groove, thereby achieving a stable connection between the first fixing block 2 and the first bearing portion 41.
如图6所示，所述第一承载部41的宽度w1大于第一连接部42的宽度w2。由此，第一承载部41可以承载宽度较宽的第一固定块2，以实现第一固定块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w5可以大于第一连接部42的宽度w2，提高第一承载部41与第一固定块2的连接稳定性。在该实施例中，如图8所示，所述第一承载部41的厚度t1和第一连接部42的厚度t2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t1也可以大于第一连接部42的厚度t2。由此，第一承载部41可以承载厚度较厚的第一固定块2，以实现第一固定块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 FIG6 , the width w1 of the first bearing portion 41 is greater than the width w2 of the first connecting portion 42. Thus, the first bearing portion 41 can bear the first fixing block 2 with a wider width, so as to achieve a better fixing effect of the first fixing block 2 on the protective sleeve 1, and the width of the first connecting portion 42 is smaller, so as to 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 w5 of the annular wall of the first bearing portion 41 can be greater than the width w2 of the first connecting portion 42, so as to improve the connection stability between the first bearing portion 41 and the first fixing block 2. In this embodiment, as shown in FIG8 , the thickness t1 of the first bearing portion 41 and the thickness t2 of the first connecting portion 42 are substantially equal. In another alternative embodiment, the thickness t1 of the first bearing portion 41 can also be greater than the thickness t2 of the first connecting portion 42. Thus, the first bearing portion 41 can bear the first fixing block 2 with a thicker thickness, so as to achieve a better fixing effect of the first fixing block 2 on the protective sleeve 1. And the thickness of the first connecting portion 42 is smaller, so as to further improve the elastic deformation ability of the first connecting portion 42. Here, the thickness direction is equivalent to the radial direction of the first connecting member 4 after the annular structure is formed (corresponding to the radial direction of the protective sleeve 1).
如图2所示，在该实施例中，所述第二固定部件还包括承载所述第二固定块3的第二连接件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，从而与所述第一固定块2一起对保护套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2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与第二固定块3一一对应，且承载所对应的第二固定块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。As shown in FIG. 2, in this embodiment, the second fixing component also includes a second connecting member 5 carrying the second fixing block 3. 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 first fixing block 2. 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 FIG. 2, 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 second fixing block 3 one by one and carries the corresponding second 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, and 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 a retractable movement space for the intestine. For example, the second connector 5 can be an elastic connector made of rubber, silicone or other materials with a certain elasticity. The second connector 5 can be arranged parallel to the support portion 11. The second connector 5 can be a closed ring structure or a connector with an interface, which is connected end to end to form a connection ring when installed at the intestinal component 9.
如图5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为环绕第二固定块3的中空环状结构，即所述第二承载部51中设置有安装孔，第二固定块3嵌设于安装孔中。为了更方便地将第二固定块3安装于第二连接件5和从第二连接件5中移除，所述第二固定块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5所示，在所述第二固定块3的侧面上至少部分设置有周向的第二固定块安装槽32，环状的所述第二承载部51嵌设在所述第二固定块安装槽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固定块安装槽，所述第二固定块3的侧面嵌设于所述第二固定块安装槽中，从而实现所述第二固定块3与所述第二承载部51的稳定连接。As shown in FIG5 , 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 second fixed block 3, that is, a mounting hole is provided in the second bearing portion 51, and the second fixed block 3 is embedded in the mounting hole. In order to more conveniently install the second fixed block 3 on the second connecting member 5 and remove it from the second connecting member 5, each side wall of the second fixed 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 FIG5 , a circumferential second fixed block mounting groove 32 is at least partially provided on the side surface of the second fixed block 3, and the annular second bearing portion 51 is embedded in the second fixed block mounting groove 32. In another alternative embodiment, the inner side of the edge of the hollow annular structure of the second bearing portion 51 may be at least partially provided with a second fixing block mounting groove circumferentially of the second fixing block, and the side surface of the second fixing block 3 may be embedded in the second fixing block mounting groove, thereby achieving a stable connection between the second 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 the protective cover 1 in advance, but may be placed in the corresponding position of the protective cover 1 by the doctor during surgery.
如图7所示，在该实施例中，所述第二承载部51的宽度w3大于第二连接部52的宽度w4。由此，第二承载部51可以承载宽度较宽的第二固定块3，以实现第二固定块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w6可以大于第二连接部42的宽度w4，提高第二承载部51与第二固定块3的连接稳定性。在该实施例中，如图8所示，所述第二承载部51的厚度t3和第二连接部52的厚度t4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t3也可以大于第二连接部52的厚度t4。由此，第二承载部51可以承载厚度较厚的第二固定块3，以实现第二固定块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. 7 , in this embodiment, the width w3 of the second bearing portion 51 is greater than the width w4 of the second connecting portion 52. Thus, the second bearing portion 51 can bear the second fixing block 3 with a wider width, so as to achieve a better fixing effect of the second fixing block 3 on the protective sleeve 1, and the width of the second connecting portion 52 is small, 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 w6 of the annular wall of the second bearing portion 51 can be greater than the width w4 of the second connecting portion 42, so as to improve the connection stability between the second bearing portion 51 and the second fixing block 3. In this embodiment, as shown in FIG. 8 , the thickness t3 of the second bearing portion 51 and the thickness t4 of the second connecting portion 52 are substantially equal. In another alternative embodiment, the thickness t3 of the second bearing portion 51 can also be greater than the thickness t4 of the second connecting portion 52. Thus, the second bearing portion 51 can bear the second fixing block 3 with a thicker thickness, so as to achieve a better fixing effect of the second fixing block 3 on the protective sleeve 1. And the thickness of the second connecting portion 52 is small, which can also further improve the elastic deformation ability of the second connecting portion 52.
如图9所示，为本发明第二实施例的吻合口保护组件应用于肠道组件的示意图。在该实施例中，所述第一固定部件中不包括第一连接件，多个第一固定块2彼此间隔设置并且彼此独立。所述第二固定部件中不包括第二连接件，多个第二固定块3彼此间隔设置并且彼此独立。所述第一固定块2的位置与所述第二固定块3的位置相对应。在手术时，可以首先将第二固定块3固定于保护套1的内表面，然后将第一固定块2一个个地放置于与第二固定块3相对应的位置处，实现第一固定块2和第二固定块3的相对固定。该种结构相比于第一实施例来说，省去了第一连接件的结构物，该组件具有更少的零部件。在未设置第一固定块2的位置处，该组件不会给组织施加任何压力，也就不会影响吻合口的正常供血。并且在肠道组织9蠕动时，多个第一固定块2之间的周向距离可以随肠道组织9蠕动自由增大或减小，即同样也给肠道组织9提供了周向的可伸缩空间。As shown in Figure 9, it is a schematic diagram of the anastomotic stoma protection component of the second embodiment of the present invention applied to the intestinal component. In this embodiment, the first fixing component does not include the first connecting member, and the plurality of first fixing blocks 2 are arranged at intervals and are independent of each other. The second fixing component does not include the second connecting member, and the plurality of second fixing blocks 3 are arranged at intervals and are independent of each other. The position of the first fixing block 2 corresponds to the position of the second fixing block 3.
