Translated fromChinese技术领域technical field
本发明涉及医疗器具技术领域，具体涉及一种食道覆膜支架固定器。The invention relates to the technical field of medical appliances, in particular to an esophagus covered stent holder.
背景技术Background technique
在现代医学领域中，食道覆膜支架主要应用于三种情况：1、食管早癌、贲门早癌内镜下治疗术后吻合口严重狭窄或吻合口癌肿复发狭窄,无再次手术指征者；食管癌放疗后狭窄、晚期食管癌、贲门癌引起的食管、贲门狭窄梗阻；各种原因引起的食管良性狭窄。2、各种原因引起的食管瘘、食管纵膈瘘、食管穿孔和破裂、食管癌术后吻合口瘘。3、食管癌放疗前预先放置支架,防止放疗中因局部组织水肿形成食管狭窄、梗阻。由此可知，食道覆膜支架对于现代医学领域来说至关重要。In the field of modern medicine, esophageal covered stents are mainly used in three cases: 1. Patients with severe anastomotic stenosis or recurrence and stenosis of anastomotic cancer after endoscopic treatment of early esophageal cancer and early cardiac cancer, and there is no indication for reoperation ; Obstruction of esophagus and cardia stenosis caused by esophageal cancer after radiotherapy, advanced esophageal cancer, and cardia cancer; Benign esophagus stenosis caused by various reasons. 2. Esophageal fistula, esophageal mediastinal fistula, esophageal perforation and rupture, esophageal cancer postoperative anastomotic leakage caused by various reasons. 3. Pre-placed stents before radiotherapy for esophageal cancer to prevent esophageal stenosis and obstruction due to local tissue edema during radiotherapy. It can be seen that the esophageal stent-graft is of great importance to the field of modern medicine.
然而，传统的食道覆膜支架在医学临床实践中，却存在一些弊端，传统的食道覆膜支架需利用挂线避免食道覆膜支架在食道使用时出现移位下滑的现象，其线的材质大多数都是耐腐蚀，高强度的细尼龙线，考虑到病人进食等客观因素，一般是利用传统的挂耳式固定器与外挂线相连接，外挂线经鼻腔到食道对食道覆膜支架进行固定，然而因为食道食管主要由环节肌层(内层)和纵行肌层(外层)组成，这两种肌肉存在收缩蠕动现象，有一定程度会造成食道支架移位，而我们的食道支架挂线在食道蠕动的作用下，会有一定的张力跟重力，传统的挂耳式固定器，因为长时间食道的蠕动还有挂耳式的牵拉，极易造成鼻腔部的外挂线对鼻翼形成切割伤，尼龙线经过食道入口反复牵拉摩擦也会对食道入口造成切割伤，给病人造成极大的痛苦，若如此，则直接对病人造成二次伤害，另一方面，挂耳式固定器美观性较差且并不便于患者进行其他的生活自理行为，且在使用的过程中，挂耳式固定器容易出现滑脱的现象。因此，提出一种食道覆膜支架固定器来解决上述问题至关重要。However, the traditional esophageal stent-graft has some drawbacks in medical clinical practice. The traditional esophageal stent-graft needs to use the hanging wire to avoid the phenomenon of displacement and sliding of the esophageal stent-graft when it is used in the esophagus, and the material of the wire is large. Most of them are corrosion-resistant, high-strength thin nylon threads. Considering objective factors such as patient eating, traditional ear-mounted fixators are generally used to connect with external hanging wires, and the external hanging wires pass through the nasal cavity to the esophagus to fix the esophageal stent-graft. , However, because the esophagus is mainly composed of the annular muscle layer (inner layer) and the longitudinal muscle layer (outer layer), these two muscles have the phenomenon of contraction and peristalsis, which will cause the esophageal stent to shift to a certain extent, and our esophageal stent hangs Under the action of peristalsis of the esophagus, the thread will have a certain tension and gravity. The traditional hanging ear fixator, because of the long-term peristalsis of the esophagus and the hanging ear type pulling, it is very easy to cause the external hanging thread in the nasal cavity to form on the nose wing. Cut wounds, the repeated pulling and friction of the nylon thread through the esophagus entrance will also cause cutting wounds to the esophagus entrance, causing great pain to the patient. If so, it will directly cause secondary damage to the patient. On the other hand, the hanging ear fixator The aesthetics is poor, and it is not convenient for patients to perform other self-care behaviors, and in the process of use, the hanging ear fixator is prone to slippage. Therefore, it is very important to propose an esophageal stent-graft fixator to solve the above problems.

The esophagus covered stent holder is used in conjunction with the inflatable bag and the elastic bag. After the sleeve is sleeved on the patient's nose, the elastic bag can be used to adjust the inside of the inflatable bag according to the actual size of the patient's nose. Air injection is performed to make the cover seat and the patient's nose as close as possible, thereby further avoiding the possible falling off and loosening of the cover seat.
简而言之，本申请技术方案通过连贯而又紧凑的结构，从根本上解决了传统挂耳式固定器与外挂线容易对患者造成切割伤的问题，更进一步解决了传统挂耳式固定器存在容易脱落、不便于患者进行其他生活自理行为的问题。In short, the technical solution of the present application fundamentally solves the problem that the traditional ear-mounted fixator and the external hanging wire easily cause cutting injuries to the patient through a coherent and compact structure, and further solves the problem of the traditional ear-mounted fixator. There are problems of easy shedding and inconvenience for patients to carry out other self-care behaviors.

请参阅图1-5，本发明提供一种技术方案：一种食道覆膜支架固定器，包括食道覆膜支架2和与食道覆膜支架2固定连接的外挂线1，还包括用于防止外挂线1对患者造成切割伤的防护组件3；1-5, the present invention provides a technical solution: an esophagus covered stent holder, comprising an esophageal covered stent 2 and an external hanging wire 1 fixedly connected to the esophageal covered stent 2, and also includes an esophagus covered stent 2 for preventing external hanging. The protective component 3 for the cutting injury caused by the thread 1 to the patient;
防护组件3包括套设于外挂线1外部与外挂线1固定连接的软胶管301、用于对鼻部进行整体封套的套座302和用于对软胶管301与套座302进行可拆卸连接的锁扣机构4，套座302为顶部与底部开口的中空结构，套座302封套于患者鼻部通过锁扣机构4与外挂线1相固定形成对食道覆膜支架2的固定拉力，通过在外挂线1外部套设有软胶管301，利用软胶管301的柔软性，则可避免外挂线对食道入口处以及患者鼻翼造成切割伤，此外，利用锁扣机构将套座与软胶管相固定，使得在患者鼻翼处设置固定器，形成对软胶管以及外挂线的拉力，此处需要强调的是，在鼻部设置固定器相比较在耳部设置固定器，则有效减少对软胶管及外挂线的牵拉运动，理由是当患者自行进行其他自理活动时，鼻部运动幅度相比较头部两侧的耳部运动幅度明显较低，则更进一步的减少了外挂线及软胶管可能对食道覆膜支架的牵拉力，此外本申请技术方案通过将套座整体套设于鼻部，并且套座的顶部于底部皆为开口结构，则避免套座内部出现空气堵塞不流通，而降低患者使用舒适度的问题，另一方面，在本领域中存在将套座采用单独悬挂式挂设于单个鼻孔外部的支撑工具，本申请技术方案与之相比较，则明显更具人性化，利用鼻部的整体牵引力，而摆脱对单个鼻孔部位的牵引力，则更加提高患者的使用舒适度；The protective assembly 3 includes a
锁扣机构4包括设置于套座302后端的两个相邻隔板403、通过铰链设置于两个隔板403之间的压板402、设置于压板402表面的卡钉块401和开设于软胶管301厚度面上与卡钉块401相卡合的卡孔，压板402为一侧表面中部凹陷的开口结构，压板402的两侧对称设置有弹性限位键，且两个隔板403的厚度面上开设有与弹性限位键相卡合的限位孔，软胶管延伸至两个隔板403之间通过压板402转动构成卡钉块401卡合至卡孔的内侧且进一步通过弹性限位键卡合至限位孔的内侧形成压板402固定于两个隔板403之间对软胶管301的卡合力，当软胶管延伸至两个隔板403之间时，转动压板402，将卡钉块401卡合至卡孔内侧，并将弹性限位键顺势卡合至限位孔的内侧，则可在完成对压板固定的基础上，达到压板利用卡钉块对卡孔的卡合力，此时若需将软胶管与压板402相互分离拆卸时，仅仅需按压弹性限位键，使其脱离于限位孔的内侧，此时转动压板，便可将卡钉块于卡孔内侧取出，此处需要强调的是，本申请所提及的弹性限位键在已授权公开的实用新型案件“一种基于BIM的建筑施工模拟的装置”(CN208281424U)中，已对弹性限位键的结构原理进行公开，故本申请不再对此进行赘述；The locking mechanism 4 includes two adjacent partitions 403 arranged at the rear end of the
还包括加强套座302内侧与患者鼻部紧密相贴的膨胀组件5，膨胀组件5包括固定设置于套座302内侧的充气囊501和通过连接管与充气囊501连通设置的弹性囊体502，由于患者的鼻部大小不同，当套座302套设于患者鼻部后，可利用弹性囊体502对充气囊501内部进行注气，则可使得膨胀后的充气囊501与患者鼻部紧贴，以避免套座在使用过程中出现松动、滑落的现象，本申请需要强调的另外一点是，充气囊501表面开设有出气孔，且出气孔上封堵有塞体，当本装置需拆卸于患者鼻部时，可拔出塞体，将充气囊501内部气体排出。It also includes an expansion assembly 5 that strengthens the inner side of the
本发明中：连接管上设置有单向阀6，通过设置有单向阀，可避免出现气体回流的现象，而影响弹性囊体对充气囊内部进行注气。In the present invention, a one-way valve 6 is arranged on the connecting pipe, and by being provided with a one-way valve, the phenomenon of gas backflow can be avoided, which affects the elastic bag body to inject gas into the inflatable bag.
本发明中：弹性囊体502的内部设置有复位弹簧，此处可参考说明书附图5，在弹性囊体内部设置有复位弹簧，其目的是，在医护人员按压弹性囊体502对充气囊进行注气时，弹性囊体在复位弹簧的作用下可尽快恢复形变，以便于医护人员持续按压弹性囊体的操作。In the present invention, the
本发明中：食道覆膜支架2包括第一固定块202和通过铰链设置于第一固定块202两侧的第二固定块201，此处将食道覆膜支架2细分为两个连接块，且第二固定块为活动设置于第一固定块的两侧，则避免食道覆膜支架深入患者食道内壁后，出现无法调节卡死至食道内壁的现象，而对患者造成伤害。In the present invention, the esophageal stent-graft 2 includes a
本发明中：第一固定块202和两个第二固定块201的顶部分别通过两个两个复位弹簧相连接，此处利用复位弹簧的弹性，进一步的使得第二固定块201尽可能的紧贴于患者食道内壁，且复位弹簧具有弹性，则避免出现第二固定块201卡死至食道内壁的现象。In the present invention, the tops of the
本发明中：两个第二固定块201相背的一侧均通过铰链设置有支撑板7，此处可参考说明书附图1，进一步可知在第二固定块的一侧活动设置有支撑板7，其目的是尽可能增加第二固定块与食道内壁的接触面积，从而减少第二固定块对食道内壁的压力，。In the present invention, the opposite side of the two second fixing blocks 201 is provided with a supporting plate 7 through a hinge. Here, referring to Figure 1 of the description, it is further known that a supporting plate 7 is movably arranged on one side of the second fixing block. , the purpose is to increase the contact area between the second fixing block and the inner wall of the esophagus as much as possible, thereby reducing the pressure of the second fixing block on the inner wall of the esophagus.
本发明中：支撑板7顶部至靠中部位置为中空结构，支撑板7底部至靠中部位置为实心结构，此处进一步将支撑板的具体结构进行限定，通过将其顶部设置为中空结构，底部设置为实心结构，增加支撑板底部的重心，则尽可能的使得支撑板7在食道内壁呈垂直状态，而避免出现支撑板混乱活动的现象。In the present invention: the top of the support plate 7 is a hollow structure to the middle position, and the bottom of the support plate 7 to the middle position is a solid structure. Here, the specific structure of the support plate is further limited. If it is set as a solid structure and the center of gravity of the bottom of the support plate is increased, the support plate 7 will be in a vertical state on the inner wall of the esophagus as much as possible, and the phenomenon of chaotic movement of the support plate will be avoided.
本发明中：两个第二固定块201的顶部均设置有连接绳，且两个连接绳相交构成对第二固定块施加拉力的勒紧绳8，此处需要强调的是，在利用食道支架助推器将食道覆膜支架推送至患者食壁时，软胶管延的端部可延伸至患者的口腔部位，则勒紧绳8一并采用软胶材质制作而成，随之延伸至患者的口腔部位，其目的是进一步的便于医护人员对第二固定块201的活动性进行控制，当第二固定块201伸入至患者食道内壁时，可拽拉勒紧绳，使得第二固定块201尽可能的向第一固定板一侧相靠拢，以便于食道覆膜支架整体伸入食道内壁，当食道覆膜支架到达食道内壁后，再松开对勒紧绳8的勒紧力，第二固定块便在复位弹簧的作用下尽可能的伸张，并使得支撑板7紧靠于食道内壁，此处需要强调的一点是，无论第二固定块如何活动，支撑板始终在其重力作用影响下，保持垂直分布状态，而不会出现卡死至食道内壁的现象。In the present invention: the tops of the two second fixing blocks 201 are provided with connecting ropes, and the intersection of the two connecting ropes constitutes the tightening rope 8 that exerts tension on the second fixing blocks. It should be emphasized here that when using the esophageal support When the booster pushes the esophageal stent-graft to the patient's esophagus, the end of the soft rubber tube can extend to the patient's oral cavity, and the tightening rope 8 is made of soft rubber material, and then extends to the patient's mouth. The purpose of the oral cavity is to further facilitate the medical staff to control the activity of the
