The utility model relates to a plastic drainage tube and a matching thrombectomy brush after cardiac surgery. The drainage tube comprises an anterior segment tube and a posterior segment tube. The anterior segment tube and a posterior segment tube adopt an integral structure, the material of which is soft silica gel, and the wall thickness of the anterior segment tube body is larger than that of the posterior segment tube body; the end of the anterior segment tube body is circular arc, and the tube wall of the anterior segment tube body is in the anterior segment tube body. Installed with a plastic wire, the plastic wire is parallel to the axial central line of the drainage pipe; at the front end of the front section of the tube body, there are several drainage side holes, and several drainage side holes are distributed in turn along the axial central line of the drainage pipe; the drainage side holes are located on the opposite wall of the plastic wire; at the front section of the tube body, there are several drainage side holes on the tube wall. A scale is set up, and the base axis of the scale is directly above the plastic metal wire, and the base axis of the scale is parallel to the plastic metal wire; the supporting de-embolization brush of the plastic drainage pipe consists of an elastic metal guide wire and a brush head, the brush head is located at the front end of the elastic metal guide wire, and the brush hair of the brush head is all backward inclined. Oblique.
【技术实现步骤摘要】
一种心脏术后可塑形引流管及配套除栓刷
本技术属于医疗器械
,特别是涉及一种心脏术后可塑形引流管及配套除栓刷。
技术介绍
目前,在胸骨正中进行开胸术后,胸骨后侧及右侧心包内需要常规留置引流管,因心脏左房后侧为卧位最低点,且心脏左室后侧为立位最低点,则经常有心包积液存留该处,而常规留置的传统引流管难以将这部分的心包积液引出,并且这部分的心包积液会对心脏形成压塞,因此需要额外进行心包穿刺或剑突下纵膈开窗,这不但增大了手术难度,而且也无形中也提高了手术风险。另外,传统引流管在插入引流部位后,将难以判断引流管前端的引流侧孔朝向,一旦引流侧孔朝向心脏,在引流过程中,由于负压会导致引流侧孔吸引并拉扯心脏,而心脏表面的微小血管会在吸引拉扯作用下,存在破裂并出血的危险,从而造成心脏的额外损伤。再有,少数患者在心脏术后的心包积液引流过程中,会在传统引流管的管体内出现血凝块等栓塞,从而导致引流不畅,而在引流不畅时,医生难以准确判断心包填塞情况,从而不可避免的影响到患者的病情。
技术实现思路
针对现有技术存在的问题,本技术提供一种心脏术后可塑形引流管及配套除栓刷,能够根据术中需要将引流管调整为合适的弯曲形状,能够使引流管前端准确到达心脏左房或左室后侧的心包积液位置;引流管在插入引流部位后,能够准确判断并控制引流侧孔的朝向,避免对心脏造成额外损伤;当引流管的管体内出现血凝块等栓塞而引流不畅时,能够快速清除管内血块栓塞,保证医生能够准确判断心包填塞情况,减少心包填塞对患者病情的影响。为了实现上述目的,本技术采用如下技术方案:一种心脏术后可塑形引流管,包括前段管体和后段管体,所述前段管体 ...
