具体实施方式detailed description
本实用新型的具体实施方式参见图1-4，一种组织分离器，包括塑料材质制作的导入器和分离器。导入器包括导入管8和锥形导向头9，锥形导向头9具有较好的导向作用，导入器为一定硬度的塑料制作，通过导入器的插入扩张为分离器建立导入通道。Referring to Fig. 1-4 for specific implementation of the present utility model, a tissue separator includes an introducer and a separator made of plastic material. The introducer includes an introduction tube 8 and a tapered guide head 9. The tapered guide head 9 has a good guiding effect. The introducer is made of plastic with a certain hardness. The insertion and expansion of the introducer establishes an introduction channel for the separator.
分离器包括连接管1，连接管1的后端连接有三通阀6，三通阀6的后端连接有注射器7；连接管1的前端连接有导入支撑管2，导入支撑管2的前端为弧形的盲端，导入支撑管2的管壁中设有若干个气腔5，靠近前端的支撑管的外壁裹设有球状囊3，位于球状囊3内腔的导入支撑管2的管壁设有若干个充气孔4。气腔5自中间向两端逐渐变薄，气腔5的厚度小于导入支撑管2的管壁的厚度，气腔5沿导入支撑管2的管壁的厚度方向呈单层分布，气腔5分布在导入支撑管2的不同横截面上。球状囊3和导入支撑管2为一体成型结构。球状囊3为聚乙烯球状囊3。The separator includes a connecting pipe 1, the rear end of the connecting pipe 1 is connected with a three-way valve 6, and the rear end of the three-way valve 6 is connected with a syringe 7; the front end of the connecting pipe 1 is connected with an introduction support pipe 2, and the front end of the introduction support pipe 2 is The arc-shaped blind end is provided with several air cavities 5 in the tube wall of the guide support tube 2, and the outer wall of the support tube near the front end is wrapped with a spherical capsule 3, and the tube wall of the guide support tube 2 located in the inner cavity of the spherical capsule 3 There are several air holes 4. The air cavity 5 gradually becomes thinner from the middle to both ends, the thickness of the air cavity 5 is smaller than the thickness of the tube wall leading into the support tube 2, and the air cavity 5 is distributed in a single layer along the thickness direction of the tube wall leading into the support tube 2, the air cavity 5 Distributed on different cross-sections of the lead-in support tube 2. The spherical capsule 3 and the introduction support tube 2 are integrally formed. The spherical capsule 3 is a polyethylene spherical capsule 3 .
气腔5的厚度小，显影面积大，不需要在导入支撑管2厚度方向设置多层气腔5，就能达到很好的显影效果，这样就能最大程度的降低管壁更薄，从而减小管径，管径越小，在医护人员操作时候就越能减轻患者的穿管痛苦。The thickness of the air chamber 5 is small, and the developing area is large. It is not necessary to arrange multi-layer air chambers 5 in the thickness direction of the leading support tube 2, so that a good developing effect can be achieved. Small tube diameter, the smaller the tube diameter, the more it can reduce the patient's pain when the medical staff operates the tube.
使用时，先通过导入器的插入扩张为分离器建立导入通道，然后将分离器沿通道植入（此时球状囊3紧贴导入支撑管2的外壁），通过超声设备可以显影出气腔5的位置，便于观察分离器的球状囊3是否到达预设位置，当球状囊3到达预设位置后，通过注射器7向球状囊3中通入空气、水或者其他液体，球状囊3逐渐变成球状达到分离组织的目的。When in use, first establish an introduction channel for the separator through the insertion and expansion of the introducer, and then implant the separator along the channel (at this time, the balloon 3 is close to the outer wall of the introduction support tube 2), and the air cavity 5 can be visualized by ultrasonic equipment position, it is convenient to observe whether the spherical capsule 3 of the separator reaches the preset position. When the spherical capsule 3 reaches the preset position, air, water or other liquids are passed into the spherical capsule 3 through the syringe 7, and the spherical capsule 3 gradually becomes spherical. To achieve the purpose of separating the organization.
