一种腹壁造瘘Ⅰ期修复的磁性装置A magnetic device for primary repair of abdominal wall fistula

技术领域technical field

本发明涉及一种医疗器械，具体涉及一种腹壁造瘘I期修复的磁性装置。The invention relates to a medical device, in particular to a magnetic device for primary repair of abdominal wall fistula.

背景技术Background technique

传统的腹壁造瘘修复技术是采用缝线设备来手工缝合，根据肠瘘的病理生理、修复机理及目前对于肠瘘的再认识，在肠瘘的急性期因感染和肠液等因素的存在，瘘口周围肠壁水肿脆弱，不论是单纯的修复，还是切除该段肠管后的肠管的端端吻合，使用传统的缝合设备均难以I期修复，所以增加了患者多次手术的痛苦且手术操作繁琐且并发症多。The traditional abdominal wall fistula repair technique is to use suture equipment to suture manually. According to the pathophysiology and repair mechanism of intestinal fistula and the current re-understanding of intestinal fistula, due to the existence of factors such as infection and intestinal fluid in the acute stage of intestinal fistula, fistula The intestinal wall around the mouth is edematous and fragile. Whether it is a simple repair or an end-to-end anastomosis of the intestinal tract after resection of the intestinal tract, it is difficult to repair it in the first stage using traditional suturing equipment, so it increases the pain of multiple operations for patients and the operation is cumbersome. And many complications.

发明内容Contents of the invention

为了克服上述现有技术存在的不足，本发明的目的在于提供一种腹壁造瘘I期修复的磁性装置，通过利用磁性吸引力完成一种腹壁造瘘I期修复，适用于各种情况的腹壁造瘘I期修复，不但大大简化手术操作，减低手术难度，简便易行，而且避免传统手工缝线设备缝合所带来的并发症，另外该装置最终可从体内取出，避免留在体内给病人带来不便和不适。In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a magnetic device for the first-stage repair of abdominal wall fistula, which can be used to complete the first-stage repair of abdominal wall fistula by using magnetic attraction force, and is suitable for abdominal walls in various situations. The one-stage repair of fistula not only greatly simplifies the operation, reduces the difficulty of operation, is simple and easy to perform, but also avoids the complications caused by traditional manual suture equipment. In addition, the device can be removed from the body eventually, avoiding leaving it in the body for the patient. cause inconvenience and discomfort.

为了达到上述目的，本发明所采用的技术方案是：In order to achieve the above object, the technical scheme adopted in the present invention is:

一种腹壁造瘘I期修复的磁性装置，由两个圆弧环柱状且大小相等的磁条1组成。A magnetic device for the first-stage repair of abdominal wall fistula, which is composed of two arc-shaped circular columnarmagnetic strips 1 of equal size.

所述的磁条1的表面均有钛或聚对二甲苯生物涂层，涂层的厚度为2纳米至20纳米。The surface of themagnetic strip 1 has a titanium or parylene biological coating, and the thickness of the coating is 2 nanometers to 20 nanometers.

通过利用两个磁条1的圆弧面朝上以及其侧壁贴合夹住正常肠壁组织完成腹壁造瘘I期修复，适用于各种腹壁造瘘I期修复，不但大大简化手术操作，减低手术难度，简便易行，而且避免传统手工缝线设备缝合所带来的并发症，另外该装置最终可从体内取出，避免留在体内给病人带来不便和不适。两个磁条的表面均有钛或聚对二甲苯生物涂层，能增强生物相容性。The first-stage repair of abdominal wall fistula is completed by using the arc surface of the twomagnetic strips 1 facing upwards and the side walls of them to clamp the normal intestinal wall tissue. It is suitable for the first-stage repair of various abdominal wall fistulas. It not only greatly simplifies the operation, It reduces the difficulty of the operation, is simple and easy to perform, and avoids the complications caused by traditional manual suture equipment. In addition, the device can be removed from the body in the end, avoiding the inconvenience and discomfort caused to the patient by staying in the body. Both strips have a titanium or parylene biocoating on the surface for enhanced biocompatibility.

具体实施方式Detailed ways

下面结合附图对本发明作更详细的说明。The present invention will be described in more detail below in conjunction with the accompanying drawings.

如图1所示，腹壁造瘘I期修复的磁性装置，由两个圆弧环柱状且大小相等的磁条1组成，所述的磁条1的表面均有钛或聚对二甲苯生物涂层，涂层的厚度为2纳米至20纳米。As shown in Figure 1, the magnetic device for the first-stage repair of abdominal wall fistula consists of two arc-shaped and equal-sizedmagnetic strips 1, and the surfaces of themagnetic strips 1 are all coated with titanium or parylene. layer, the thickness of the coating is 2 nm to 20 nm.

本发明的工作原理是：首先测量瘘口的内径，选择两个磁条1的宽度之和小于瘘口3的内径的腹壁造瘘I期修复的磁性装置，然后如图2和图3所示将两个磁条1置入瘘口3，围绕瘘口3的边缘适当缝几针牵引线并提起，将两个磁条1的圆弧面朝上以及其侧壁贴合夹住正常肠壁组织后，取掉缝线即可，最后如图4所示，在瘘口3修复完成时再取出磁条。对于瘘口3外置的情况，瘘口3修复后两个磁条由于位于皮下，只需局部麻醉下取出。The working principle of the present invention is: first measure the inner diameter of the fistula opening, select the magnetic device for the first-stage repair of abdominal wall fistula whose width sum of the twomagnetic strips 1 is smaller than the inner diameter of the fistula opening 3, and then as shown in Figure 2 and Figure 3 Put the twomagnetic strips 1 into the fistula opening 3, sew a few stitches of traction thread around the edge of the fistula opening 3 and lift it up, and put the arc surface of the twomagnetic strips 1 upwards and their side walls to clamp the normal intestinal wall After the organization, just take off the suture, finally as shown in Figure 4, take out the magnetic strip again when thefistula 3 is repaired. For the external situation of thefistula 3, after the repair of thefistula 3, the two magnetic strips only need to be taken out under local anesthesia because they are located under the skin.

本发明适用于各种腹壁造瘘I期修复，不但大大简化手术操作，减低手术难度，简便易行，而且避免传统手工缝线设备缝合所带来的并发症，另外另外该装置最终可从体内取出，避免留在体内给病人带来不便和不适。两个磁条的表面均有钛或聚对二甲苯生物涂层，能增强生物相容性。The present invention is suitable for the first-stage repair of various abdominal wall fistulas. It not only greatly simplifies the operation, reduces the difficulty of the operation, is simple and easy to perform, but also avoids the complications caused by traditional manual suture equipment. Take it out to avoid inconvenience and discomfort to the patient if left in the body. Both strips have a titanium or parylene biocoating on the surface for enhanced biocompatibility.
