Example Embodiment

[0014] The accompanying drawings are specific embodiments of the present invention. like Figure 1 to Figure 3 As shown, the percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing device includes a catheter sheath 1, a soft catheter 2, a guide wire 8, a push rod 9 and an exchange rod 10, wherein:

[0015] The catheter sheath 1 is a rigid hollow structure, and its shape is like an injection needle or a puncture needle. After puncturing the abdominal wall, it stays on the abdominal wall to support and protect the flexible catheter 2 and the guide wire 8 to enter and exit the abdominal cavity; the catheter sheath 1 can be inserted into the puncture Needle.

[0016] Soft catheter 2: its head end is provided with a circle of balloon 3, the balloon 3 and the soft catheter 2 can be integrally connected, the interior of the soft catheter 2 is tapered, the balloon 3 is connected to the channel 4, and the channel 4 is also integrally fixed in the soft catheter.

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a percutaneous minimally invasive intra-abdominal gastrointestinal tract pushing and pressing device. The catheter comprises a catheter sheath, a soft catheter, a guide wire and a push rod, the catheter sheath and the push rod are of hard hollow structures, a circle of balloon is arranged at the end of the soft catheter, the balloon is connected with a channel, and the channel and the soft catheter are fixed together; the soft catheter can penetrate through the catheter sheath, the inner wall of the end, provided with the balloon, of the soft catheter is conical, and the push rod is arranged on the guide wire in a sleeving mode and then penetrates into the soft catheter. An exchange rod is further arranged, the guide wire can be inserted into the exchange rod, and the exchange rod can be inserted into the puncture needle. In the using process, gastrointestinal tracts can be effectively avoided, the gastrointestinal tracts are prevented from being punctured, and therefore potential safety hazards are reduced.
