Description

一种临时的瓣膜和主动脉滤器一体化装置A temporary valve and aortic filter integrated device

技术领域technical field

背景技术Background technique

心脏瓣膜病是严重危害人类生命健康的疾病,随着人口老龄化时代的到来,越来越多主动脉瓣疾病患者呈现出高龄高危的特征。随着医学技术的发展,目前出现了经皮主动脉瓣植入术(TAVR),该手术以其小切口,低创伤,恢复快等特点被越来越多用于临床各类疾病的治疗。然而,由于该手术针对主动脉瓣狭窄患者,术中需要球囊扩张等危险操作,容易出现瓣膜球囊扩张后的继发严重主动脉瓣反流,继而导致患者血流动力学崩溃甚至死亡,因此在这一操作过程中,安置临时瓣膜来减少左室血液回流成为可能的预防该严重并发症的方式。同时,由于多数患者瓣叶有严重钙化,在球囊扩张过程中,瓣叶的钙化可能被球囊挤压脱落后经主动脉进入脑、四肢等脏器导致相关器官栓塞坏死的严重并发症,所以安置临时滤器节流脱落的钙化组织成为可行的干预手段。Heart valve disease is a disease that seriously endangers human life and health. With the advent of the ageing population, more and more patients with aortic valve disease are showing the characteristics of advanced age and high risk. With the development of medical technology, percutaneous aortic valve implantation (TAVR) has appeared, which is more and more used in the treatment of various clinical diseases due to its small incision, low trauma, and quick recovery. However, since this operation is aimed at patients with aortic valve stenosis and requires balloon dilation and other dangerous operations during the operation, it is prone to secondary severe aortic valve regurgitation after valve balloon dilation, which in turn leads to hemodynamic collapse and even death of the patient. Therefore, during this procedure, the placement of a temporary valve to reduce left ventricular regurgitation becomes a possible way to prevent this serious complication. At the same time, due to the severe calcification of valve leaflets in most patients, in the process of balloon expansion, the calcification of valve leaflets may be squeezed off by the balloon and then enter the brain, limbs and other organs through the aorta, resulting in serious complications of embolization and necrosis of related organs. Therefore, the placement of a temporary filter to restrict the shed calcified tissue has become a feasible intervention.

本实用新型的一种使用方法:A kind of using method of the present utility model:

步骤1,处于未充注造影剂状态的“C”型的球囊2呈卷曲状态,将此时的球囊2连带与所述球囊2的上端面固定连接的滤器4及与所述球囊2的下端面对称固定连接的两片瓣叶3环绕并贴紧于所述第二管道5的侧壁上;再将第二管道5连同裹好的球囊2置于所述输送管腔6的通道C中;Step 1, the "C"-shaped balloon 2 in a state of not being filled with a contrast agent is in a crimped state, and the balloon 2 at this time is connected with the filter 4 fixedly connected to the upper end surface of the balloon 2 and the balloon 2. The lower end of the balloon 2 is symmetrically and fixedly connected to the two leaflets 3 around and close to the side wall of the second pipe 5; then the second pipe 5 and the wrapped balloon 2 are placed in the delivery pipe In channel C of cavity 6;

步骤2,将导向丝经由一侧股动脉血管或其他血管入路穿入患者体内,沿主动脉抵达指定位置后,输送管腔6借助第二管道5与导向丝的连接,由导向丝牵引至指定位置;当输送管腔6到达指定位置后,伸出第二管道5,将球囊2部分置于患者升主动脉处;Step 2: The guide wire is inserted into the patient's body through one side of the femoral artery or other vascular access. After reaching the designated position along the aorta, the delivery lumen 6 is connected with the guide wire by the second pipeline 5, and the guide wire is drawn to the patient. The designated position; when the delivery lumen 6 reaches the designated position, the second conduit 5 is extended, and the balloon 2 is partially placed at the ascending aorta of the patient;

步骤3,将主动脉瓣扩张球囊经由另一侧股动脉或其他血管入路穿入患者体内并到达病变主动脉瓣上方,所述主动脉瓣扩张球囊为介入瓣膜介入过程中所需的用于扩张狭窄的主动脉瓣的球囊装置;Step 3, the aortic valve dilation balloon is inserted into the body of the patient through the other side of the femoral artery or other vascular access and reaches above the diseased aortic valve, the aortic valve dilation balloon is required in the process of interventional valve intervention. A balloon device for dilating a narrowed aortic valve;

步骤4,球囊2到达指定位置后,通过所述第一管道1及用于连接第一管道1与球囊2的连接管7对球囊2进行填充处理,原本干瘪的球囊2经由第一管道注射造影剂并因充注造影剂膨胀成“C”型;且因“C”型结构及球囊2本身的软性结构,球囊2的任一端可弯入另一端的内侧,球囊2会更加精确的适应贴合主动脉直径,同时由于主动脉非一致性直径情况,可以在操作过程中实时适应主动脉直径的变化,也不会因此剐蹭主动脉壁导致主动脉壁损伤而出现主动脉破裂等严重并发症;同时与球囊2连接的滤器4因其柔性结构也跟随撑开,所述滤器4的内侧一面关于所述第二管道5的外壁紧贴,所述滤器4的开口打开进入作业;所述与球囊2连接的双叶结构瓣叶3也对应撑开,所述两个瓣叶3的内侧一面关于所述第二管道5的外壁紧贴,并进入手术期间的临时工作状态;此时由于C型球囊结构,本装置的瓣膜和滤器自外包裹主动脉瓣扩张球囊远端的输送系统,当主动脉瓣球囊自体外注射造影剂充盈后,患者自体的瓣膜上的钙化组织部分松散脱落,经过本装置的瓣膜进入滤器4内部并被滤器4阻拦于滤器内,从而避免钙化组织径血流进入脑等脏器导致脑梗等脏器栓塞事件。同时由于主动脉瓣扩张球囊在充盈后会经由体外快速抽除造影剂从而恢复主动脉瓣前向血流,这一操作同时会导致严重主动脉瓣的毁坏从而出现主动脉瓣关闭不全,本装置的瓣膜可防止血流自主动脉弓及降主动脉回流回左室,避免左室血液瘀滞容量负荷增加而出现的循环崩溃这一严重心血管并发症;Step 4: After the balloon 2 reaches the designated position, the balloon 2 is filled through the first pipeline 1 and the connecting tube 7 used to connect the first pipeline 1 and the balloon 2, and the shriveled balloon 2 passes through the first pipeline 1 and the balloon 2. A pipeline injects contrast agent and expands into a "C" shape due to filling the contrast agent; and due to the "C" shape structure and the soft structure of the balloon 2 itself, either end of the balloon 2 can be bent into the inside of the other end, and the balloon Balloon 2 will more accurately fit the diameter of the aorta, and at the same time, due to the non-uniform diameter of the aorta, it can adapt to changes in the diameter of the aorta in real time during the operation, and will not rub against the aortic wall and cause damage to the aortic wall. Serious complications such as aortic rupture occur; at the same time, the filter 4 connected to the balloon 2 is also stretched due to its flexible structure, and the inner side of the filter 4 is in close contact with the outer wall of the second pipeline 5, and the filter 4 The opening of the valve is opened to enter the operation; the two-leaflet structure valve 3 connected to the balloon 2 is also correspondingly stretched, and the inner side of the two valve leaflets 3 is close to the outer wall of the second pipeline 5, and enters the operation. Temporary working state during the period; at this time, due to the C-shaped balloon structure, the valve and filter of the device wrap the delivery system at the distal end of the aortic valve dilation balloon from outside. Part of the calcified tissue on the autologous valve is loose and falls off, and enters the filter 4 through the valve of the device and is blocked by the filter 4 in the filter, thereby preventing the blood flow of the calcified tissue from entering the brain and other organs and causing cerebral infarction and other organ embolism events. At the same time, because the aortic valve dilation balloon will quickly remove the contrast agent through the external body after filling to restore the forward blood flow of the aortic valve, this operation will also cause serious damage to the aortic valve and cause aortic valve insufficiency. The valve of the device can prevent blood flow from the aortic arch and descending aorta back to the left ventricle, and avoid the serious cardiovascular complication of circulatory collapse caused by the increase of left ventricular blood stasis volume load;

步骤5,在主动脉瓣扩张球囊撤出体内至体外后,介入主动脉瓣输送系统可经由原主动脉瓣扩张球囊的导引丝平行并穿过本装置的瓣膜及滤器所构成的环抱结构并到达患者自体主动脉瓣位置,并根据介入瓣膜相关程序释放植入介入瓣膜。以上过程因球囊2的“C”型结构,可以更好地对应介入瓣膜、介入球囊等装置输送系统的直径变化,达到同一个临时的瓣膜滤器结构适应术中不同介入输送装置的直径变化,而始终紧密封闭升主动脉从而保证本装置的瓣膜与滤器与升主动脉及介入瓣膜、球囊输送系统的紧密贴合;Step 5: After the aortic valve dilation balloon is withdrawn from the body to the outside of the body, the interventional aortic valve delivery system can be paralleled through the guide wire of the original aortic valve dilation balloon and pass through the encircling structure formed by the valve and the filter of the device. And reach the position of the patient's native aortic valve, and release the implanted interventional valve according to the relevant procedures of the interventional valve. Due to the "C"-shaped structure of the balloon 2, the above process can better correspond to the diameter changes of the interventional valve, interventional balloon and other device delivery systems, so that the same temporary valve filter structure can adapt to the diameter changes of different interventional delivery devices during surgery. , and always tightly seal the ascending aorta to ensure the close fit of the valve and filter of the device with the ascending aorta, the interventional valve, and the balloon delivery system;

步骤6,手术结束后,撤离介入瓣膜输送系统,通过所述第一管道1对球囊2内部进行抽除造影剂,是球囊2恢复干瘪状态,再通过第二管道5收入输送管腔6中,由导向丝牵引出患者体内,最后再将导向丝抽出,并对伤口进行对应处理。Step 6: After the operation, the interventional valve delivery system is evacuated, and the inside of the balloon 2 is extracted through the first pipeline 1 to remove the contrast agent, so that the balloon 2 is restored to a shriveled state, and then is collected into the delivery lumen 6 through the second pipeline 5. In the middle, the guide wire is pulled out of the patient's body, and finally the guide wire is pulled out, and the wound is treated accordingly.
