Disposable safe built-in peritoneal dialysis tunnel puncture needle

A disposable safe built-in peritoneal dialysis tunnel puncture needle comprises a puncture needle body and a hollow safety helmet, one end of the safety helmet is open, the tail end of the puncture needle body is connected with a catheter through a connecting device, and the disposable safe built-in peritoneal dialysis tunnel puncture needle is characterized in that the connecting device wraps the end of the catheter. And the connecting device wraps the end part of the catheter, so that the situation that the catheter is separated from the puncture needle due to the resistance of fat of a patient in the operation process is effectively reduced, and the success rate of the operation is improved. 一次性安全型内置式腹膜透析隧道穿刺针，包括穿刺针和中空的安全帽，安全帽一端开口，穿刺针尾端通过连接装置与导管连接，其特征在于连接装置包裹住导管的端部，本实用新型通过连接装置将导管和穿刺针连接在一起，且连接装置将导管的端部包裹住，从而有效减少在手术过程中，因为患者脂肪的阻力导致导管与穿刺针脱离，从而提高了手术的成功率。
