管腔吻合支撑扩张器Lumen anastomosis support dilator

技术领域technical field

本发明涉及医疗外科手术管腔吻合辅助器械领域，尤其涉及一种管腔吻合支撑扩张器。The invention relates to the field of auxiliary instruments for lumen anastomosis in medical and surgical operations, in particular to a lumen anastomosis support expander.

背景技术Background technique

管腔吻合术是临床上一种基础手术形式，包括管腔损伤修复、管腔移植、管腔搭接、管腔缝合与修补等，可以用于血管、淋巴道、输精管、胆道、气管、支气管等领域，是常用的重建管腔功能的有效治疗方法。应用十分广泛，常见于各类外科手术中，比如皮瓣移植、断肢再植、血管意外损伤、器官移植、动静脉内瘘吻合、淋巴管吻合、输精管吻合、胆道吻合、气管吻合等等。伴随显微手术器械、显微缝线和手术显微镜的不断发展，手工小(微)管腔吻合技术逐步成熟，可吻合管腔的口径越来越细。然而即便对于经验丰富的外科手术医生来说，要完成一例完美的管腔吻合术也并不是很容易的，尤其是上面提到的小微管腔吻合术。Lumen anastomosis is a basic surgical form in clinical, including lumen damage repair, lumen transplantation, lumen overlap, lumen suture and repair, etc. It can be used for blood vessels, lymphatic channels, vas deferens, bile ducts, trachea, bronchi It is an effective treatment method commonly used to reconstruct lumen function. It is widely used in various surgical operations, such as flap transplantation, replantation of severed limbs, accidental vascular injury, organ transplantation, arteriovenous fistula anastomosis, lymphatic anastomosis, vas deferens anastomosis, biliary anastomosis, tracheal anastomosis, etc. With the continuous development of microsurgical instruments, micro sutures and operating microscopes, manual small (micro) lumen anastomosis technology has gradually matured, and the diameter of the anastomotic lumen is getting thinner and thinner. However, even for experienced surgeons, it is not easy to complete a perfect lumen anastomosis, especially the small microlumen anastomosis mentioned above.

首先管腔两个断端相对的吻合口要准确地对合，不能有扭转、狭窄、外翻或内翻情况，也就是说要求两断端对合时内膜对内膜，肌层对肌层。这样的愈合瘢痕最少，通畅率亦增高。所以要求两断端的口径尽量相等，可用等直径的扩张器或扩张管腔专用的镊子扩张，然而矛盾的是对于一些小管腔又非常重视无创伤技术，不许用镊子钳夹待吻合的管腔内膜和肌层，否则通畅率会降低。需要柔性或无创伤的内支撑来实现吻合口的对合。First of all, the anastomosis of the two opposite ends of the lumen should be accurately aligned, and there should be no torsion, stenosis, valgus or varus. Floor. Such healing scars are minimal and the patency rate is increased. Therefore, it is required that the diameters of the two ends should be as equal as possible, which can be expanded with an equal-diameter dilator or special forceps for expanding the lumen. However, the paradox is that for some small lumen, atraumatic techniques are attached great importance, and forceps are not allowed to clamp the tube to be anastomosed. endoluminal and muscularis, otherwise the patency rate will be reduced. A flexible or atraumatic inner support is required to achieve apposition of the anastomosis.

其次，以血管为例，血管作为一种管腔，对于血管吻合术来说，需要血管显露，控制血流才能提供无血视野完成手术操作；根据血管大小及解剖部位，选用不同类型的无损伤血管钳、柔软而有弹性的胶质带，或用球囊导管经血管腔内阻断血流。阻断血流后血管壁的弹性回缩、塌陷，管腔变小甚至闭塞，前后壁常相互贴合不易分开，对缝合操作造成很大障碍，缝合时还容易会刺穿对侧血管壁。操作难度大、效率低、耗时较长，导致血流阻断时间较长，风险大。一些医生会自制一些填塞物来辅助缝合，虽然可以解决部分问题，但效率仍不高、功能单一，且不规范。Secondly, taking the blood vessel as an example, the blood vessel is a kind of lumen. For vascular anastomosis, the blood vessel needs to be exposed and the blood flow can be controlled to provide a bloodless field of view to complete the operation; according to the size and anatomy of the blood vessel, different types of non-invasive Vascular forceps, soft and elastic colloidal strips, or balloon catheters are used to block blood flow through the lumen of the vessel. After the blood flow is blocked, the blood vessel wall elastically retracts and collapses, and the lumen becomes smaller or even blocked. The operation is difficult, inefficient, and time-consuming, resulting in a long blood flow blocking time and a high risk. Some doctors will make some self-made packing materials to assist suture. Although some problems can be solved, the efficiency is still low, the function is single, and it is not standardized.

在本方案中，在进行吻合手术时，医生可以利用器械(如显微镊、持针器等)夹持支撑主体，并将支撑主体放置于管腔中，当器械松开后，弹性材料或形状记忆材料制成的支撑主体可以回弹并适度撑起管腔，便于医生进行后续的吻合操作。当吻合完成一部分后，可以利用连接杆将支撑主体经未缝合的缺口处取出，并继续后续的缝合。因此，该管腔吻合支撑扩张器可快速扩张管腔，辅助手术治疗，减少管壁损伤，提高管腔吻合效率与成功率。In this solution, when performing anastomosis, the doctor can use instruments (such as micro forceps, needle holders, etc.) to hold the support body, and place the support body in the lumen. When the instrument is released, the elastic material or The support body made of shape memory material can rebound and prop up the lumen moderately, which is convenient for doctors to perform subsequent anastomosis operations. When a part of the anastomosis is completed, the supporting body can be taken out through the unsutured gap by using the connecting rod, and the subsequent suture can be continued.

较佳地，所述连接杆上设置有多个所述支撑主体。Preferably, a plurality of the supporting bodies are provided on the connecting rod.

在本方案中，多个支撑主体可以适用于多个管腔，而且多个支撑主体可以具有多种不同的外径，因此一个管腔吻合支撑扩张器可以适用于不同直径的管腔。In this solution, multiple support bodies may be applicable to multiple lumens, and multiple support bodies may have multiple different outer diameters, so one lumen anastomosis support dilator may be applicable to lumens with different diameters.

较佳地，所述连接杆的两端各设置有一所述支撑主体。Preferably, each of the two ends of the connecting rod is provided with the supporting body.

在本方案中，两个支撑主体可以分别置于两个待吻合的管腔中，因此利用一个管腔吻合支撑扩张器就可以实现两个管腔的吻合，使得缝合时两个管腔相对固定，便于缝合操作，同时减少手术中所需器材的数量。In this solution, the two support bodies can be placed in the two lumens to be anastomosed respectively, so the anastomosis of the two lumens can be achieved by using one lumen anastomosis support dilator, so that the two lumens are relatively fixed during suturing , to facilitate the suture operation, while reducing the number of equipment required in the operation.

较佳地，所述支撑主体为回转体。Preferably, the supporting body is a rotating body.

在本方案中，由于管腔的横截面大多基本为圆形，支撑主体为回转体能够较好地适配于管腔，以利于吻合手术。In this solution, since most of the cross-sections of the lumen are substantially circular, the supporting body is a rotatable body, which can be better adapted to the lumen, so as to facilitate anastomosis.

较佳地，所述支撑主体包括主体部，所述主体部的至少一端部设置有锥形部，所述锥形部的外径自所述主体部向外递减，所述主体部的最大外径大于所述锥形部的最大外径；Preferably, the support main body includes a main body portion, at least one end of the main body portion is provided with a tapered portion, the outer diameter of the tapered portion decreases outward from the main body portion, and the maximum outer diameter of the main body portion is greater than the maximum outer diameter of the tapered portion;

和/或，所述连接杆两端的两个所述支撑主体的轴心线之间的夹角为0-180°。And/or, the included angle between the axis lines of the two supporting bodies at both ends of the connecting rod is 0-180°.

在本方案中，主体部具有较大的外径，可用于支撑管腔，锥形部可以为圆锥、圆锥台等形状，锥形部能够方便地插入管腔中，从而使得整个支撑主体较为容易地进入管腔。支撑主体可以仅设置一个锥形部，也可以在主体部的两端各设置一个锥形部，以使得支撑主体能够从两个方向插入管腔中。即，支撑主体的形状可以为中间外径大两头外径小，或一端外径大一端外径小。具体地，支撑主体可以为球形、半球形、椭球形、半椭球型、圆锥形、圆台形、水滴型、橄榄型、葫芦型等类似形状。In this solution, the main body part has a larger outer diameter and can be used to support the lumen, and the conical part can be in the shape of a cone, a truncated cone, etc., and the conical part can be easily inserted into the lumen, thereby making the entire supporting body easier into the lumen. The support body may be provided with only one tapered portion, or one tapered portion may be provided at both ends of the body portion, so that the support body can be inserted into the lumen from two directions. That is, the shape of the support body may be such that the middle outer diameter is larger and the outer diameters are smaller at both ends, or the outer diameter at one end is larger and the outer diameter is smaller at the end. Specifically, the supporting body may be spherical, hemispherical, ellipsoidal, semi-ellipsoidal, conical, truncated, drop-shaped, olive-shaped, gourd-shaped, and the like.

由于两个待缝合管腔的开口之间可能具有不同的相对位置，因此连接杆两端的两个支撑主体的轴心线之间可以设置为共线、平行、或呈其他的角度，以适应不同情况的管腔吻合需要。Since the openings of the two lumens to be sutured may have different relative positions, the axis lines of the two supporting bodies at both ends of the connecting rod can be set to be collinear, parallel, or at other angles to suit different In cases where lumen anastomosis is required.

较佳地，各个所述支撑主体的主体部的最大外径相同或不同。Preferably, the maximum outer diameters of the main body portions of each of the supporting bodies are the same or different.

在本方案中，同一连接杆上的两个支撑主体的主体部可以具有相同的最大外径，以适用于外径相同的管腔之间的吻合。此外，两个支撑主体也可以具有不同的最大外径，以适用于直径不同的管腔间的吻合。In this solution, the main body parts of the two supporting bodies on the same connecting rod may have the same maximum outer diameter, so as to be suitable for anastomosis between lumens with the same outer diameter. In addition, the two support bodies can also have different maximum outer diameters, so as to be suitable for anastomosis between lumens with different diameters.

较佳地，所述管腔吻合支撑扩张器还包括操作杆，所述操作杆的端部连接于所述连接杆的中部。Preferably, the lumen anastomosis support dilator further comprises an operating rod, and the end of the operating rod is connected to the middle part of the connecting rod.

在本方案中，利用操作杆能够推动、拉引支撑主体，以调整支撑主体的位置和角度，使用者可以利用操作杆将支撑主体从管腔中取出。In this solution, the support body can be pushed and pulled by the operating rod to adjust the position and angle of the support body, and the user can use the operating rod to take out the support body from the lumen.

较佳地，所述连接杆可弯折，以使得不同所述支撑主体之间的相对位置可调。Preferably, the connecting rod can be bent, so that the relative positions between the different supporting bodies can be adjusted.

在本方案中，由于连接杆可弯折，因此在取出支撑主体时，支撑主体的位置和角度可以自动调整，以避免损伤管腔。而且连接杆可以弯折为任意角度，能够适用于不同的吻合手术。连接杆可以为直杆，另外，由于特定吻合手术的需要，连接杆也可预塑为弯管。连接杆可以采用与支撑主体相同的材料，进一步地，连接杆可以与支撑主体一体成型。连接杆与支撑主体也可以由不同的材料制成，本领域的技术人员可以根据实际情况选择材料，进一步地，连接杆可以与支撑主体一体成型，但不限于一体成型。In this solution, since the connecting rod can be bent, when the support body is taken out, the position and angle of the support body can be automatically adjusted to avoid damage to the lumen. Moreover, the connecting rod can be bent into any angle, which can be applied to different anastomosis operations. The connecting rod can be a straight rod, or, due to the needs of specific anastomotic procedures, the connecting rod can also be pre-molded into a curved tube. The connecting rod can be made of the same material as the supporting body, and further, the connecting rod can be integrally formed with the supporting body. The connecting rod and the supporting body can also be made of different materials, and those skilled in the art can select materials according to actual conditions. Further, the connecting rod and the supporting body can be integrally formed, but not limited to integral forming.

较佳地，所述支撑主体设置有中空腔，所述支撑主体的一端开设有与所述中空腔相连通的通孔；或，所述支撑主体的两端分别开设有与所述中空腔相连通的通孔。Preferably, the support body is provided with a hollow cavity, and one end of the support body is provided with a through hole communicating with the hollow cavity; or, both ends of the support body are respectively provided with a hole connected with the hollow cavity. through holes.

在本方案中，支撑主体可以具有中空腔，以使得支撑主体容易被压缩。支撑主体开设有通孔，以便于中空腔的成型。若支撑主体的两端都开设有通孔，则中空腔为贯穿的，因此在吻合手术的过程中，管腔中的流体可以通过中空腔继续保持流动，可解决管腔缝合过程中由于中断管腔内部的流体流动而导致的管腔壁塌陷影响缝合的问题。支撑主体一端或两端的通孔可以为一个或多个。可以理解的是，支撑主体也可以不设置中空腔，从而使得支撑主体具有较大的支撑力。In this solution, the support body may have a hollow cavity so that the support body can be easily compressed. The support body is provided with a through hole to facilitate the molding of the hollow cavity. If both ends of the support body are provided with through holes, the hollow cavity is penetrating. Therefore, during the anastomosis operation, the fluid in the lumen can continue to flow through the hollow cavity, which can solve the problem of the interruption of the tube during the lumen suture process. Collapse of the lumen wall due to fluid flow inside the lumen affects the problem of suturing. There may be one or more through holes at one or both ends of the support body. It can be understood that, the support body may not be provided with a hollow cavity, so that the support body has a greater supporting force.

较佳地，所述连接杆开设有流体通道，所述流体通道与所述支撑主体的所述中空腔相连通。Preferably, the connecting rod is provided with a fluid channel, and the fluid channel communicates with the hollow cavity of the support body.

在本方案中，管腔中的流体可以在中空腔内流动，中空腔中的流体可以经流体通道被引流至预设的位置，可以根据实际情况设置流体通道，以利于吻合手术的进行。具体地，可以使得中空腔的一端连通于所述流体通道，因此流入中空腔中的流体完全从流体通道中排出，或中空腔中的流体全部从流体通道注入。此外，当连接杆上设置有多个支撑主体时，各支撑主体的中空腔可以通过流体通道相连通，在缝合手术时，不同的支撑主体设置于不同的管腔中，一管腔中的流体可以经中空腔和流体通道流入另一管腔中，从而实现在进行缝合手术时，不同管腔之间能够连通。In this solution, the fluid in the lumen can flow in the hollow cavity, the fluid in the hollow cavity can be drained to a preset position through the fluid channel, and the fluid channel can be set according to the actual situation to facilitate the anastomosis operation. Specifically, one end of the hollow cavity can be communicated with the fluid channel, so the fluid flowing into the hollow cavity is completely discharged from the fluid channel, or the fluid in the hollow cavity is completely injected from the fluid channel. In addition, when a plurality of support bodies are provided on the connecting rod, the hollow cavities of each support body can be communicated through a fluid channel. During the suturing operation, different support bodies are arranged in different lumen, and the fluid in one lumen It is possible to flow into another lumen through the hollow lumen and fluid channel, thereby enabling communication between the different lumen during suturing.

本发明的积极进步效果在于：该管腔吻合支撑扩张器可以应用于管腔吻合手术，例如血管、淋巴道、输精管、胆道、气管、支气管等管腔的吻合。医生可以利用器械(如显微镊、持针器等)夹持支撑主体，并将支撑主体放置于管腔中，当器械松开后，弹性材料制成的支撑主体可以回弹并适度撑起管腔，便于医生进行后续的吻合操作。由于支撑主体具有贯穿的中空腔，因此在吻合手术的过程中，管腔中的流体可以通过中空腔继续保持流动，可解决管腔缝合过程中由于中断管腔内部的流体流动而导致的管腔壁塌陷影响缝合的问题。当缝合完成一部分后，可以利用连接杆将支撑主体经未缝合的缺口处取出，并完成后续的缝合。因此，该管腔吻合支撑扩张器可快速扩张管腔，并在管腔吻合过程中保持扩张状态，辅助手术操作，减少管壁损伤，提高吻合效率与成功率。The positive improvement effect of the present invention is that the lumen anastomosis support dilator can be applied to lumen anastomosis operations, such as anastomosis of blood vessels, lymphatic channels, vas deferens, bile ducts, trachea, bronchi and other lumen. The doctor can use instruments (such as micro forceps, needle holders, etc.) to hold the support body and place the support body in the lumen. When the instrument is released, the support body made of elastic material can rebound and moderately prop up The lumen is convenient for doctors to perform subsequent anastomosis operations. Since the support body has a hollow cavity through it, during the anastomosis procedure, the fluid in the lumen can continue to flow through the hollow cavity, which can solve the problem of the lumen caused by interrupting the fluid flow inside the lumen during the lumen suturing process. Wall collapse affects the problem of suture. When a part of the stitching is completed, the supporting body can be taken out through the unstitched gap by using the connecting rod, and the subsequent stitching can be completed. Therefore, the lumen anastomosis support dilator can rapidly expand the lumen, and maintain the expanded state during the lumen anastomosis, assist the surgical operation, reduce the damage of the tube wall, and improve the efficiency and success rate of anastomosis.

具体实施方式Detailed ways

下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在的实施例范围之中。The present invention is further described below by means of examples, but the present invention is not limited to the scope of the examples.

为更好的理解本发明，下面列出本发明应用的最常用的三种管腔缝合术类型：For a better understanding of the present invention, the three most common types of lumen sutures for which the present invention is applied are listed below:

1.端侧吻合术1. End-to-side anastomosis

端侧吻合术在临床上作旁路移植时广泛使用，一般受体管腔作纵直线切口或椭圆形切口，供体管腔端面修剪成斜面，长度大于受体管腔直径。End-to-side anastomosis is widely used in clinical bypass grafting. Generally, a longitudinal straight or oval incision is made in the recipient lumen, and the end face of the donor lumen is trimmed into a bevel, and the length is greater than the diameter of the recipient lumen.

2.端端吻合术2. End-to-end anastomosis

两缝合管腔101端面应尽可能相同，或可修剪成斜面来扩大吻合口面积。或者采用内部支撑方式来获取相近的缝合端面。The end faces of the twosuture lumens 101 should be the same as possible, or they can be trimmed into bevels to expand the area of the anastomosis. Or use internal support to obtain similar suture end faces.

3.侧侧吻合术3. Lateral anastomosis

侧侧吻合，通常将待吻合的两管腔靠近，并用特制的管腔钳夹住吻合部位的侧壁，做对应的纵向切口。For side-to-side anastomosis, the two lumens to be anastomosed are usually approached, and a special lumen clamp is used to clamp the side wall of the anastomosis site to make a corresponding longitudinal incision.

实施例1Example 1

如图1至图5所示为本发明实施例1的管腔吻合支撑扩张器，其包括支撑主体1和连接杆2，支撑主体1由弹性材料或形状记忆材料制成，即使发生变形也可以自膨胀为初始的形状，即能提供良好径向支撑作用，柔性外表面又不伤及管腔内表面，在特制器械的夹持下比较容易地回缩。支撑主体1用于至少部分地置于管腔101中以扩张管壁100，支撑主体1开设有贯穿的中空腔11；连接杆2连接于支撑主体1。As shown in FIGS. 1 to 5 , the lumen anastomosis support dilator according toEmbodiment 1 of the present invention includes asupport body 1 and a connectingrod 2 . Thesupport body 1 is made of elastic material or shape memory material, which can be used even if it is deformed.

Two lumen anastomosis support dilators are used, and thesupport body 1 of one lumen anastomosis support dilator is inserted into The end opening of onelumen 101 supports the tube wall 100 (the lumen anastomosis support dilator is not shown in the figure), and thesupport body 1 of the other lumen anastomosis support dilator is inserted into the side of theother lumen 101 The openings hold up thewall 100 , so that the end opening of onelumen 101 is sutured to the side opening of theother lumen 101 . During the anastomosis procedure, the fluid in thelumen 101 can continue to flow through thehollow lumen 11 . For the specific suturing process, reference may be made to the above-mentioned suturing process of end-to-end anastomosis, which will not be repeated here.

此外，如图5所示，还可以使用两个本实施例的管腔吻合支撑扩张器进行侧侧吻合术，具体可参见图5，利用两个管腔吻合支撑扩张器，分别将一支撑主体1从一管腔101的侧部开口插入管腔101中，以进行两个管腔101侧侧吻合。具体缝合过程可参考上述端端吻合术和端侧吻合术的缝合过程，在此不再赘述。In addition, as shown in FIG. 5 , two lumen anastomosis support dilators of the present embodiment can also be used for side-to-side anastomosis.

For the specific suturing process, reference may be made to the above-mentioned suturing process of end-to-end anastomosis and end-to-side anastomosis, which will not be repeated here.

连接杆2上可以设置有多个支撑主体1，因此利用一个管腔吻合支撑扩张器就可以进行两个管腔101间的吻合，而且，多个支撑主体1的主体部13可以具有多种不同的外径，因此一个管腔吻合支撑扩张器可以适用于不同直径的管腔101。在本实施例中，连接杆2的两端各设置有一支撑主体1，两个支撑主体1可以分别置于两个待吻合的管腔101中，因此利用一个管腔吻合支撑扩张器就可以实现两个管腔101的吻合，使得缝合时两个管腔101相对固定，便于缝合操作，同时减少手术中所需器材的数量。The connectingrod 2 may be provided with a plurality of supportingbodies 1, so that an anastomosis between twolumens 101 can be performed by using one lumen anastomosis support dilator, and themain body parts 13 of the plurality of supportingbodies 1 may have various different Therefore, one lumen anastomosis support dilator can be applied tolumen 101 of different diameters. In this embodiment, asupport body 1 is provided at each end of the connectingrod 2, and the twosupport bodies 1 can be respectively placed in the twolumen 101 to be anastomosed. Therefore, a lumen anastomosis support dilator can be used to realize the The anastomosis of the twolumens 101 makes the twolumens 101 relatively fixed during suture, which facilitates the suture operation and reduces the number of equipment required in the operation.

同一连接杆2上的两个支撑主体1可以具有相同的最大外径，以适用于直径相同的管腔101之间的吻合。此外，两个支撑主体1的主体部13也可以具有不同的最大外径，以适用于直径不同的管腔101间的吻合。在某些实施例中，连接杆2的中部也可以设置一个或多个支撑主体1，以满足不同的管腔吻合手术需要。The two supportingbodies 1 on the same connectingrod 2 may have the same maximum outer diameter, so as to be suitable for anastomosis betweenlumens 101 with the same diameter. In addition, themain body parts 13 of the two supportingbodies 1 may also have different maximum outer diameters, so as to be suitable for anastomosis betweenlumens 101 with different diameters. In some embodiments, one or more supportingbodies 1 may also be provided in the middle of the connectingrod 2 to meet the needs of different lumen anastomosis operations.

由于两个待缝合管腔的开口之间可能具有不同的相对位置，因此连接杆2两端的两个支撑主体1的轴心线之间的夹角可以为0-180°，以使得两个支撑主体1的轴心线之间可以设置为共线、平行或呈其他的角度，以适应不同情况的管腔吻合手术的需要。Since the openings of the two lumens to be sutured may have different relative positions, the included angle between the axis lines of the two supportingbodies 1 at both ends of the connectingrod 2 can be 0-180°, so that the two supports The axis lines of themain body 1 can be set to be collinear, parallel or at other angles, so as to meet the needs of lumen anastomosis in different situations.

连接杆2可弯折，以使得连接杆2上不同支撑主体1之间的相对位置可调，防止在取出支撑主体1时损伤管腔101，连接杆2可以弯折为任意角度，以适用于不同的吻合手术。由于特定吻合手术的需要，连接杆2也可预塑为弯管，如在本实施例中，连接杆2与一支撑主体1的轴心线之间的夹角为45°。优选地，连接杆2可以为弹性材料或形状记忆材料制成，进一步地，连接杆2与支撑主体1可以为一体成型结构，连接杆2采用与支撑主体1相同的材料制成，其呈条状或柱状，根据需求可设置不同长度。连接杆2可以顺应性地发生形变，以实现管腔101的形状，同时还可以保持一定角度以便于控制支撑主体1的位置和角度。The connectingrod 2 can be bent, so that the relative positions between different supportingbodies 1 on the connectingrod 2 can be adjusted to prevent damage to thelumen 101 when the supportingbody 1 is taken out. The connectingrod 2 can be bent at any angle to be suitable for Different anastomosis procedures. Due to the needs of a specific anastomosis operation, the connectingrod 2 can also be pre-molded into a curved tube.

实施例2Example 2

如图6至图11为本发明实施例2的管腔吻合支撑扩张器，本实施例与实施例1基本相同，所不同的是：连接杆2的两端各设置有一支撑主体1的轴心线在一条直线上，两个支撑主体1的轴心线共线。因此本实施例中的管腔吻合支撑扩张器可以适用于端端吻合术(如图7和图11)。在手术时，用器械(如显微镊、持针器等)夹持支撑主体1，较为尖的端部作前进方向，分别放入两待缝合管腔101的端口内，用以获得基本相同的端面尺寸形状，连接杆2留于管腔101的外部。待缝合完成约三分之二左右，通过拉动管腔101外的连接杆2配合器械夹持支撑主体1外表，分别将两管腔101内的支撑主体1取出；然后继续缝合剩余部分至手术完成。6 to 11 are the lumen anastomosis support dilator according to the second embodiment of the present invention. This embodiment is basically the same as the first embodiment, the difference is that the two ends of the connectingrod 2 are each provided with an axis supporting themain body 1 The lines are on a straight line, and the axis lines of the two supportingbodies 1 are collinear. Therefore, the lumen anastomosis support dilator in this embodiment may be suitable for end-to-end anastomosis (as shown in FIG. 7 and FIG. 11 ). During the operation, the supportingbody 1 is clamped with instruments (such as micro tweezers, needle holders, etc.), and the sharper ends are placed in the forward direction, respectively, and placed into the ports of the twolumens 101 to be sutured, so as to obtain substantially the same The size and shape of the end face, the connectingrod 2 is left outside thelumen 101. After about two-thirds of the suture is completed, pull the connectingrod 2 outside thelumen 101 to cooperate with the instrument to clamp the outer surface of thesupport body 1, and take out thesupport body 1 in the twolumen 101 respectively; then continue to suture the remaining part until the operation is completed .

连接杆2还可以设有流体通道21，流体通道21的两端与支撑主体1的中空腔11相连通。管腔101中的流体可以在中空腔11内流动，中空腔11中的流体可以经流体通道21被引流至另一管腔中。The connectingrod 2 may also be provided with afluid channel 21 , and both ends of thefluid channel 21 are communicated with thehollow cavity 11 of thesupport body 1 . The fluid in thelumen 101 can flow in thehollow lumen 11 , and the fluid in thehollow lumen 11 can be drained into another lumen through thefluid channel 21 .

具体在本实施例中，中空腔11的一端连通于流体通道21，由于中空腔11的端部直接连通于流体通道21，因此流入中空腔11中的流体完全从流体通道21中排出，或中空腔11中的流体全部从流体通道21注入。Specifically in this embodiment, one end of thehollow cavity 11 is connected to thefluid channel 21. Since the end of thehollow cavity 11 is directly connected to thefluid channel 21, the fluid flowing into thehollow cavity 11 is completely discharged from thefluid channel 21, or thehollow cavity 11 is completely discharged from thefluid channel 21. The fluid in thecavity 11 is all injected from thefluid channel 21 .

例如在图7中，流体通道21的两端分别与一支撑主体1的中空腔11的端部连通，因此两个支撑主体1的中空腔11通过流体通道21相连通。不同的支撑主体1设置于不同的管腔101中，一管腔101中的流体可以经中空腔11和流体通道21流入另一管腔101中，从而实现在进行缝合手术时，不同管腔101之间能够连通，手术过程不会中断管腔101内流体的流动。For example, in FIG. 7 , both ends of thefluid channel 21 are respectively communicated with the ends of thehollow cavity 11 of a supportingbody 1 , so thehollow cavities 11 of the two supportingbodies 1 are communicated through thefluid channel 21 .Different support bodies 1 are arranged indifferent lumen 101, and the fluid in onelumen 101 can flow into anotherlumen 101 through thehollow lumen 11 and thefluid channel 21, so as to realize thedifferent lumen 101 during the suturing operation. Communication between them is possible, and the flow of fluid in thelumen 101 will not be interrupted during the surgical procedure.

一个管腔吻合支撑扩张器上的多个支撑主体1可以为相同的尺寸(如图6、图7、图9至图11)，也可以为不同的尺寸(如图8)。当管腔吻合支撑扩张器上设置有一大一小的两个支撑主体1时，管腔吻合支撑扩张器能够适配于多种直径的管腔101，提高管腔吻合支撑扩张器的适用范围，对于不同直径的管腔101，使用不同尺寸的支撑主体1。A plurality ofsupport bodies 1 on a lumen anastomosis support dilator may be of the same size (as shown in FIG. 6 , FIG. 7 , FIG. 9 to FIG. 11 ), or may be of different sizes (as shown in FIG. 8 ). When the lumen anastomosis support dilator is provided with two supportingbodies 1, one large and one small, the lumen anastomosis support dilator can be adapted to lumen 101 of various diameters, which improves the application range of the lumen anastomosis support dilator. Fordifferent diameter lumens 101, different sizes ofsupport bodies 1 are used.

所以可以不中断内部物质流动的情况下进行管腔吻合手术。在可替代的实施例中也可以使中空腔11的一端闭合、两端闭合或内部为实心结构，实心结构的支撑主体的支撑力更大；或者在连接杆2上不设置流体通道21或为实心结构，实心结构的连接杆的推拉力更大，以避免管腔101中的流体进入管腔吻合支撑扩张器中，这种情况适用于手术中需要中断管腔101内物质流动的情况。Therefore, an anastomosis can be performed without interrupting the flow of internal materials. In an alternative embodiment, thehollow cavity 11 can also be closed at one end, closed at both ends, or a solid structure inside, and the support body of the solid structure has a larger supporting force; With a solid structure, the connecting rod of the solid structure has a larger push-pull force to prevent fluid in thelumen 101 from entering the lumen anastomosis support dilator. This situation is suitable for the situation where the flow of substances in thelumen 101 needs to be interrupted during surgery.

管腔吻合支撑扩张器还包括操作杆3，具体地，如图9所示，操作杆3的端部连接于连接杆2的中部。利用操作杆3能够推动、拉引支撑主体1，以调整支撑主体1的位置和角度，使用者可以利用操作杆3将支撑主体1从管腔101中取出。The lumen anastomosis support dilator further includes an operatingrod 3 , specifically, as shown in FIG. 9 , the end of the operatingrod 3 is connected to the middle of the connectingrod 2 . Thesupport body 1 can be pushed and pulled by the operatingrod 3 to adjust the position and angle of thesupport body 1 , and the user can use the operatingrod 3 to take thesupport body 1 out of thelumen 101 .

实施例3Example 3

如图12至图16所示为本发明实施例3的管腔吻合支撑扩张器，本实施例与实施例1基本相同，所不同的是：连接杆2的两端各设置有一支撑主体1，两个支撑主体1的轴心线相互垂直。因此本实施例的管腔吻合支撑扩张器应用于端侧吻合术时，具体可参见图12，连接杆2为弯管，连接杆2上的两个支撑主体1的轴心线的延伸方向基本相互垂直。待吻合的两个管腔101中，一管腔101的侧部开设有开口，管腔吻合支撑扩张器的一个支撑主体1从该侧部开口塞入该管腔101中，另一支撑主体1则塞入到另一管腔101的端部开口中，塞入过程可以使用器械(如显微镊、持针器等)夹持支撑主体1以缩小其体积，同时利用支撑主体1的锥形部12作为前进的端部，以利于支撑主体1进入管腔101中。在部分完成缝合后，可以将支撑主体1从未缝合的缺口中取出，随后完成全部的缝合。Figures 12 to 16 show the lumen anastomosis support dilator according toEmbodiment 3 of the present invention. This embodiment is basically the same asEmbodiment 1, the difference is that each end of the connectingrod 2 is provided with a supportingbody 1, The axes of the two supportingbodies 1 are perpendicular to each other. Therefore, when the lumen anastomosis support dilator of this embodiment is applied to end-to-side anastomosis, see FIG. 12 for details. The connectingrod 2 is a curved tube, and the extension directions of the axis lines of the two supportingbodies 1 on the connectingrod 2 are basically perpendicular to each other. Among the twolumen 101 to be anastomosed, onelumen 101 is provided with an opening on the side, one supportingbody 1 of the lumen anastomosis supporting dilator is inserted into thelumen 101 from the side opening, and the other supportingbody 1 is inserted into thelumen 101. Then it is inserted into the end opening of theother lumen 101. In the process of inserting, thesupport body 1 can be clamped with instruments (such as micro forceps, needle holders, etc.) to reduce its volume, and the tapered shape of thesupport body 1 can be used at the same time. Theportion 12 serves as an advancing end to facilitate the entry of thesupport body 1 into thelumen 101 . After the stitching is partially completed, thesupport body 1 can be removed from the unstitched notch, and then the entire stitching is completed.

上述弯杆可以为直接加工成型而得到的弯杆，也可以理解为实施例2中连接杆2为可弯折的材料，通过弯折实施例2中的直杆能够得到本实施例的弯杆。The above-mentioned bending rod can be a bending rod obtained by direct processing and molding, and it can also be understood that the connectingrod 2 in the second embodiment is a bendable material, and the bending rod of this embodiment can be obtained by bending the straight rod in the second embodiment. .

如图14所示，在侧部开口的管腔101中，由于支撑主体1具有中空腔11，因此该管腔101内的流体可以正常流动。而且连接杆2上还可以设置流体通道21，流体通道21可以将两个支撑主体1的中空腔11相连通，使得两个管腔101间的流体能够相流通。在可替代的实施例中，也可以不设置流体通道21(图12和图13)，或者改变流体通道21和中空腔11的导流方向，以满足不同的手术需要。As shown in FIG. 14 , in thelumen 101 with the side opening, since thesupport body 1 has thehollow cavity 11 , the fluid in thelumen 101 can flow normally. In addition, afluid channel 21 may be provided on the connectingrod 2 , and thefluid channel 21 can communicate with thehollow cavities 11 of the two supportingbodies 1 , so that the fluids between the twolumens 101 can communicate with each other. In alternative embodiments, thefluid channel 21 may not be provided ( FIG. 12 and FIG. 13 ), or the flow direction of thefluid channel 21 and thehollow cavity 11 may be changed to meet different surgical needs.

同一管腔吻合支撑扩张器上的支撑主体1可以为相同的外径(图12和图13)，也可以具有不同的形状和尺寸(图14至图16)，以适配于不同的管腔101，本领域的技术人员可以根据实际情况作出调整。Thesupport body 1 on the same lumen anastomosis support dilator can have the same outer diameter (Fig. 12 and Fig. 13), or can have different shapes and sizes (Fig. 14 to Fig. 16) to fitdifferent lumens 101. Those skilled in the art can make adjustments according to the actual situation.

如图17至图21所示为本发明实施例4的管腔吻合支撑扩张器，本实施例与实施例1基本相同，所不同的是：连接杆2的两端各设置有一支撑主体1，两个支撑主体1的轴心线相互平行。因此本实施例的管腔吻合支撑扩张器能够应用于侧侧吻合术，连接杆2呈V型，连接杆2上的两个支撑主体1并列地设置。此时两个待吻合的管腔101的侧部都开设有开口，两个支撑主体1分别对应从侧部开口塞入两个管腔101中，塞入过程可以使用器械(如显微镊、持针器等)夹持支撑主体1以缩小其体积，同时利用支撑主体1的锥形部12作为前进的端部，以利于支撑主体1进入管腔101中。在部分完成缝合后，可以将支撑主体1从未缝合的缺口中取出，随后完成全部的缝合。支撑主体1的中空腔11使得管腔101内的流体不被堵塞，且连接杆2上也可以设置有流体通道21，流体通道的两端分别与两个支撑主体1的中空腔11相连通，以使得两个管腔101间的流体能够相连通。在可替代的实施例中，也可以不设置流体通道21，或者改变流体通道21和中空腔11的导流方向，以满足不同的手术需要。Figures 17 to 21 show the lumen anastomosis support dilator according to Embodiment 4 of the present invention. This embodiment is basically the same asEmbodiment 1, the difference is that asupport body 1 is provided at each end of the connectingrod 2, The axes of the two supportingbodies 1 are parallel to each other. Therefore, the lumen anastomosis support dilator of this embodiment can be applied to side-to-side anastomosis, the connectingrod 2 is V-shaped, and the two supportingbodies 1 on the connectingrod 2 are arranged side by side. At this time, openings are provided on the sides of the twolumen 101 to be anastomosed, and the two supportingbodies 1 are respectively inserted into the twolumen 101 from the side openings. The inserting process can use instruments (such as micro forceps, Needle holder, etc.) to clamp thesupport body 1 to reduce its volume, and at the same time use the taperedportion 12 of thesupport body 1 as an advancing end to facilitate thesupport body 1 entering thelumen 101 . After the stitching is partially completed, thesupport body 1 can be removed from the unstitched notch, and then the entire stitching is completed. Thehollow cavity 11 of thesupport body 1 prevents the fluid in thelumen 101 from being blocked, and the connectingrod 2 may also be provided with afluid channel 21. Both ends of the fluid channel are communicated with the twohollow cavities 11 of thesupport body 1, respectively. So that the fluid between the twolumens 101 can be communicated.
